Integrating Smartphone Sensor Technology to Enhance Fine Motor and Working Memory Skills in Pediatric Obesity: A Gamified Approach

Childhood obesity remains a pervasive global challenge, often accompanied by deficits in working memory and fine motor skills among affected children. These deficits detrimentally impact academic performance. Despite limited evidence, home-based interventions targeting both fine motor skills and working memory remain underexplored. Leveraging game-based approaches holds promise in behavior modification, self-management of chronic conditions, therapy adherence, and patient monitoring. In this study, a novel smartphone-based game was meticulously developed to target the enhancement of working memory and fine motor skills in a cohort of thirty-two obese or overweight children. Over two weeks, participants engaged in regular gameplay sessions within the comfort of their homes. Pretest and post-test assessments yielded compelling evidence of significant improvements, with statistical significance established at a robust 95% confidence level. Notably, participants exhibited a progressive trend of improvement in their gameplay performance. Recognizing the profound impact of academic achievement on future socioeconomic trajectories, regardless of weight management outcomes, the importance of bolstering cognitive skills cannot be overstated. This innovative intervention offers a pragmatic and cost-effective solution to empower children to cultivate essential cognitive abilities within their home environment. By fostering the development of working memory and fine motor skills, this intervention holds promise in facilitating improved academic performance and, consequently, enhancing long-term prospects for these children.

Assessing implicit computational thinking in game‐based learning: A logical puzzle game study

AbstractTo date, extensive work has been devoted to incorporating computational thinking in K‐12 education. Recognizing students' computational thinking stages in game‐based learning environments is essential to capture unproductive learning and provide appropriate scaffolding. However, few reliable and valid computational thinking measures have been developed, especially in games, where computational knowledge acquisition and computational skill construction are implicit. This study introduced an innovative approach to explore students' implicit computational thinking through various explicit factors in game‐based learning, with a specific focus on Zoombinis, a logical puzzle‐based game designed to enhance students' computational thinking skills. Our results showed that factors such as duration, accuracy, number of actions and puzzle difficulty were significantly related to students' computational thinking stages, while gender and grade level were not. Besides, findings indicated gameplay performance has the potential to reveal students' computational thinking stages and skills. Effective performance (shorter duration, fewer actions and higher accuracy) indicated practical problem‐solving strategies and systematic computational thinking stages (eg, Algorithm Design). This work helps simplify the process of implicit computational thinking assessment in games by observing the explicit factors and gameplay performance. These insights will serve to enhance the application of gamification in K‐12 computational thinking education, offering a more efficient method to understanding and fostering students' computational thinking skills. Practitioner notesWhat is already known about this topic Game‐based learning is a pedagogical framework for developing computational thinking in K‐12 education. Computational thinking assessment in games faces difficulties because students' knowledge acquisition and skill construction are implicit. Qualitative methods have widely been used to measure students' computational thinking skills in game‐based learning environments. What this paper adds Categorize students' computational thinking experiences into distinct stages and analyse recurrent patterns employed at each stage through sequential analysis. This approach serves as inspiration for advancing the assessment of stage‐based implicit learning with machine learning methods. Gameplay performance and puzzle difficulty significantly relate to students' computational thinking skills. Researchers and instructors can assess students' implicit computational thinking by observing their real‐time gameplay actions. High‐performing students can develop practical problem‐solving strategies and exhibit systematic computational thinking stages, while low‐performing students may need appropriate interventions to enhance their computational thinking practices. Implications for practice and/or policy Introduce a practical method with the potential for generalization across various game‐based learning to better understand learning processes by analysing significant correlations between certain gameplay variables and implicit learning stages. Allow unproductive learning detection and timely intervention by modelling the reflection of gameplay variables in students' implicit learning processes, helping improve knowledge mastery and skill construction in games. Further investigations on the causal relationship between gameplay performance and implicit learning skills, with careful consideration of more performance factors, are expected.

Pedaling to Performance: Exploring the Effects of Pre-Tournament Cycling on Rocket League Esports Performance

ABSTRACT Purpose Exercise has been well documented to elicit cognitive benefits; therefore, we aimed to examine the effect on performance of a single bout of cycling exercise before an esports tournament. Methods Twenty healthy males (age, 24 ± 6 yr; height, 177.3 ± 7.3 cm; body mass, 80.7 ± 20.9 kg; ranked between Gold 1 and Champion 3) participated in a randomized, counterbalanced crossover study involving 1) a 20-min cycling exercise bout at 60%–70% heart rate reserve or 2) 20 min of rest before competing in an esports tournament. Tournaments consisted of 10 paired, rank-matched Rocket League 1 vs. 1 matches played in three series. Participants were assessed before and after the tournament for hemodynamics, cognition, and gameplay mechanics. Heart rate was monitored throughout the tournament, with gameplay performance and post-match surveys completed after each match. Results Exercising before the tournament led to higher initial fatigue (P = 0.002), higher average heart rates throughout the tournament (P < 0.001), lower perceived individual performance in series 1 (P = 0.03), lower overall perceived opponent performance (P = 0.03), and improved goal percentage in series 3 (P = 0.04) compared with rest. Participant save percentage decreased over time in both conditions (P = 0.04). No differences were observed in cognition measures, gameplay mechanics, or hemodynamics. Conclusions A single bout of cycling exercise completed before a Rocket League 1 vs. 1 tournament had no negative effects on performance or wins. It did, however, lower perceived match performance and fatigue at the beginning of the tournament while improving goal percentage during the last series.

Prophylactic Knee Bracing in Offensive Linemen of the National Football League: A Retrospective Analysis of Usage Trends, Player Performance, and Major Knee Injury.

Offensive linemen in American football are prone to high-energy valgus forces to the knee, leading to associated injuries. Some offensive linemen in the National Football League (NFL) wear prophylactic knee braces (PKB) to prevent ligamentous injury. This purpose of the study was to compare injury rates and performance between NFL offensive linemen who wear PKB and those who do not. It was hypothesized that brace wear would be associated with fewer major knee injuries and no difference in gameplay performance. Cohort study; Level of evidence, 3. For the 2014 through 2020 NFL seasons, offensive linemen with at least 200 game snaps per regular season were identified. Players were grouped by PKB status (bracers vs nonbracers) based on visualization of bilateral, dual-hinged metal knee braces as part of gameday uniforms on publicly available imaging databases and/or game videos. Major knee injuries, defined as those requiring the missing of games, were identified using publicly available data. Performance was assessed with Pro Football Focus grades for each season. Rates of major knee injury were compared between groups with the 2-sample Z test for proportions, and performance grades were compared with the unpaired t test. For the cumulative study period, bracers demonstrated a significantly lower rate of major knee injuries than nonbracers (0.013 vs 0.049 injuries per player, respectively; P = .04). Isolated MCL injury was the most common injury for nonbracers. There was no group difference in performance for the cumulative study period or during most individual seasons. Yearly prevalence of PKB usage declined steadily from 16.3% in 2014 to 5.6% in 2020. A subgroup analysis of rookie players demonstrated an overall downtrend in usage during the study period as well. Results indicated that knee brace prophylaxis by NFL offensive linemen was associated with a reduced risk of major knee injury without a significant difference in performance when compared with nonbracers. Despite this, the prevalence of PKB declined over the study period.

Exploring the effect of the Group Size and Feedback of non-player character spectators in virtual reality exergames.

Despite the widespread interest in leveraging non-player characters (NPCs) to enhance gameplay experiences, there is a gap in understanding of how NPC spectators (i.e., those virtual characters in the scene that watch users' actions) affect players. For instance, the impact of NPC spectators' presence and feedback on players' performance and experience has not been studied, especially in virtual reality (VR) exergames. This paper aims to fill this gap and reports two user studies that assess their effect on such games. Study 1 explored the impact of having NPC spectators present and their feedback available in a gesture-based VR exergame and found having NPC spectators and their feedback could improve players' game performance, experience, and exertion. Based on Study 1's results, we further explored two characteristics of the spectators-their group size (small/large) and their feedback (with/without). The results show that (1) a large spectator number is more helpful since it improves the overall game experience (higher competence, flow, immersion), increases AvgHR% (the average heart rate percentage divided by the maximum heart rate), and enhances performance (improved players' combo performance and increased gesture success rate for particular gesture); (2) spectator feedback is instrumental in improving players' performance (higher gesture success rates, more combos performed successfully, more monster's combos prevented), enhancing game experience (positive affect, competence, flow, and immersion), and reducing negative game experience, increasing exertion (AvgHR% and burned more calories). Based on the results, we derived two main design recommendations for VR exergames that could pave the way for improving gameplay performance and game experience, especially among young adults.

Effects of Failure on California Sea Lion (Zalophus californianus) Gameplay Strategies and Interest in a Cognitive Task: Implications for Cognitive Enrichment in Pinnipeds

Cognitive enrichment for professionally managed species has become more prevalent in recent years in both zoological and research settings and has been encouraged as a means of welfare enhancement. However, the task’s difficulty must be specifically tailored as it can impact the successful nature of the sessions, as tasks that are too simple or difficult may not be perceived as enriching by the animals. While pinnipeds are common in zoos, aquariums, and research facilities, few studies have explored the use of cognitively challenging enrichment in this species, and the level of difficulty and presence of failure on animal success and engagement in this type of session has not been assessed. In this study, gameplay strategies during computerized enrichment sessions were evaluated before and after a game that introduced failure, or the loss of opportunity to complete a level for a reward after an incorrect movement. Interest in participation during the session, measured as the latency without contact, was also tested as a proxy for this enrichment’s effect on welfare. When incorrect movements resulted in a short pause and removed the opportunity to finish individual levels for a reward, all three sea lions tested significantly reduced the amount of time spent on each of several strategies they employed, but significantly increased the number of button presses per strategy, suggesting the animals focused on more precise movements as their proficiency improved. Two sea lions also showed a significant decline in latency without contact following the introduction of failure in the form of a single opportunity to complete a task for a reward after previously having unlimited opportunities, while one maintained a low latency without contact across both test conditions. The results suggest that more cognitively challenging tasks incorporating failure did not cause a reduction in gameplay performance and session interest in sea lions. Individual variation was also noted in strategy use, emphasizing the importance of evaluating the individual in terms of enrichment provision.

Investigation of visual and game-playing performance under different genders, display and operation interfaces

Technological progress has led to 3D displays becoming a trend in the market, yet few studies have evaluated 3D techniques in head-mounted displays (HMD) under different topics simultaneously, such as gender and operation interfaces. This study investigated these research issues to examine the effect of gender (male, female), display interface (2D TV, 3D HMD), and operation interface (joystick, keyboard) on usability, accuracy, change of critical flicker frequency (change of CFF), Simulator Sickness Questionnaire (SSQ), and iGroup Presence Questionnaire (IPQ). Thirty participants with no NBA2K15 basketball game-playing experience were recruited in the experiment. The results showed significant effects of gender on accuracy, usability, and change of CFF, where males demonstrated higher accuracy, lower usability, and lower visual fatigue. In addition, display interface had significant effects on usability, SSQ and IPQ. The 2D TV was associated with higher usability and lower SSQ and IPQ. Furthermore, the operation interface had significant effects on accuracy, usability, change of CFF, and IPQ. The joystick led to a higher usability and IPQ but a lower change of CFF. The results provide suggestions to game players that choosing 2D TVs with joysticks generates greater usability. In addition, although they achieved a higher presence, players also had greater visual fatigue when wearing HMDs. This study concluded that males have better performance in accuracy and visual fatigue while females have better usability when playing basketball games.

Evaluating the effectiveness of game-based learning for teaching refugee children Arabic using the integrated LEAGUÊ-GQM approach

ABSTRACT Game-based learning (GBL) is widely utilised in various domains and continues to receive interest and attention from researchers and practitioners alike. However, there is still a lack of empirical evidence concerning its effectiveness, making GBL evaluation a critical undertaking. This paper proposes an integrated approach for planning and executing GBL evaluation studies and presents its application by evaluating the effectiveness of a GBL approach to improve the Arabic reading skills of migrant refugee children in an informal learning setup. The study focuses on how children’s age group, learning modality preference, and prior mobile experience affect their learning, usability, and gameplay performance. A quasi-experiment with a one-group pretest-posttest design was conducted with 30 children (5–10 years old) from migrant refugee backgrounds. The results show a statistically significant improvement in their reading assessment score. The results also outline a clear impact of children’s age groups on their learning gain, usability score, and total levels played. Moreover, learning modality preference and prior mobile experience both had a statistically significant effect related to usability and gameplay performance parameters. However, no effect was found on learning gain. Based on the findings, some design recommendations are suggested for more inclusive design focusing on user characteristics.

Connecting symbolic fractions to their underlying proportions using iterative partitioning.

Fractions are a challenging mathematics topic for many elementary and middle school students, and even for adults. However, a growing body of developmental research suggests that young children can reason about visually presented proportions, well before fraction instruction, providing insight into how fractions might be introduced to improve learning. We designed a card game to teach first and second grade children (N = 195, including a racially and economically diverse sample from the United States) about fractions in one of three ways. In the Actively Divided condition we iteratively divided an area model into equal-sized units, in the Predivided condition we used an area model with the end-state of the Actively Divided condition, and in the Nondivided condition we used a continuous representation of the fraction magnitude that was not divided into unit-sized parts. Children in the actively divided condition demonstrated larger improvements matching symbolic fractions and visual fractions (i.e., pie charts) than children in the other two conditions. Posthoc analyses of children's gameplay revealed that the actively divided condition may have provided a more optimal level of difficulty for young children than the predivided condition, which was particularly difficult, and the nondivided condition, which was trivially easy. These differences in gameplay performance provide insights into possible mechanisms for our results. We discuss open research questions highlighted by this work and implications of these findings for both the development of proportional reasoning and fraction learning.

The entity belief of concentration ability predicts cognitive load, failure-attribution, and flow experience when using a virtual reality device

ABSTRACT Attentional control theory indicates that concentration is considered an important variable that contributes to learning. There are some devices for players to practice their concentration, but there are few virtual reality (VR) designs which can increase the level of difficulty for students to discipline their mental concentration with incongruent hands-on movement. To address this gap, a VR system named Tracking Fun was designed, which requires hand-eye coordination to move a ball to a target hole. To explore the effect of playing Tracking-fun on players’ concentration performance, the study explored the relationship among entity beliefs of concentration ability (EBCA), intrinsic cognitive load (ICL), failure attribution of VR operation (FAVRO), flow experience, and gameplay performance. Students from a skills-based senior high school took part in this experimental research, and 259 valid questionnaires were returned. The research results showed that: EBCA can positively predict cognitive load; EBCA can positively predict FAVRO; ICL and flow have a negative correlation; FAVRO can negatively predict flow experience when interacting with VR; and flow can negatively predict gameplay performance. Based on the results, enriching the opportunity and difficulty level of Tracking-fun can enhance players’ concentration. Follow-up research suggestions are proposed.

Effects of a two-stage physical education teacher education programme on preservice teachers’ specialised content knowledge and students’ game-play in a student-centred Sport Education-Step Game approach

This study aimed to examine the effects of a physical education teacher education programme on (a) preservice teachers’ (PSTs') specialised content knowledge (SCK), and (b) the game-play development of their students, during a student-centred Sport Education-Step Game Approach (SE-SGA) unit. Three PSTs selected by convenience sampling (22–24 years old), their 60 eighth-grade students (three classes: 38 boys, 22 girls, Mage = 13.3), and a mentoring team (one teacher educator, one university supervisor, and one cooperating teacher) participated in the study. The PSTs participated in a two-stage programme where they learned how to teach volleyball using SE-SGA, and then implemented an SE-SGA unit during their school placement. Using audio/video data from 30 lessons, we examined PSTs' SCK (content development, depth of content knowledge) on a lesson-by-lesson basis. We also assessed the 2v2 game-play performance of PSTs’ students across three assessment points. Descriptive statistics were computed for SCK scores and repeated measures analysis of variances were used to analyse variance in game-play variables over time. Results showed improvement in PSTs’ SCK and students’ game-play. The PSTs showed strong SCK, with index levels above the 3.0 cut point, and progressive use of informing, refining, and applying-game tasks over time. Students improved in most game-play variables (namely ‘serve’, ‘reception’, ‘setting’) and the ‘game performance index’ over time. Student game-play development seemed to be strongly influenced by an interdependent interaction between PSTs’ SCK and additional situated, model-based features of content development (i.e. extensive application of knowledge in competition events, the problem-solving focus of the refining tasks).

A Systematic Review of the Effects of Caffeine on Basketball Performance Outcomes

Simple SummaryCaffeine is a stimulant of the central nervous system widely utilized by many athletes to enhance endurance, strength, and power-based sports performances. Whether ergogenic enhancements following caffeine ingestion result in improvements in sports-specific skills performance has received less attention. In basketball, the ability to execute certain tasks with accuracy, such as shooting and passing, are key factors affecting the outcome of the sport. Besides being able to excel in accuracy-based tasks, the possession of strong physical attributes, including vertical jump height, sprint speed and agility, are also key components to basketball performance. In this review, an overview of the effects of caffeine on basketball-related skill tasks and physical aspects of performance deemed important for the game is provided. One of the key focal points is that the efficacy of caffeine is influenced by a multitude of determinants that have an overall impact on the ergogenic capacity of caffeine. Proper awareness of these determinants allows basketball players, coaches, and trainers to have better insights and knowledge in applying caffeine to improve basketball-related performances.Caffeine is an ergogenic aid in many sports, including basketball. This systematic review examines the effects of caffeine on basketball-related skill tasks along with physical aspects of performance deemed important for the game. A systematic search was conducted across three databases (PubMed, SPORTDiscus and Web of Science) to identify randomized-controlled trials which examined the effect of caffeine on basketball performance outcomes including: free-throw, 3-point shooting accuracy, dribbling speed, vertical jump height, and linear and repeated sprints. Forty-six articles were identified of which 10 met the inclusion criteria. Improvements in vertical jump were identified in four of five studies, agility in two of four studies, and in linear and repeated sprints in two of three studies. No deterioration in basketball skills performance was observed in any studies. It is suggested that caffeine is useful for basketball players to improve the physical aspects of their game-play performance but there is little evidence of any change in skill-based performance at present. Further research should clarify the effects of caffeine on basketball performance in women and the role of individual genetic variation on caffeine metabolism. Basketball players and coaches should be aware of the properties of caffeine before ingesting it as an ergogenic supplement.

Gestalt perception: A game designed to explore players’ gameplay self-efficacy and anxiety reflected in their learning effects

Gestalt perception relates to inferring a holistic scene from separate elements. Using this theory, an application game named Gestalt Puzzle was designed for students to play by recognizing a few parts of an image to reason the whole image of a particular object. Cognitive style can be divided into field independence (FI) and field dependence (FD) depending on individuals’ ability to identify minor components of a whole image. To understand the gameplay learning effect, this study explored how players’ field-independent cognitive style (FI-CS) interacted with their gameplay performance as the two types of cognitive styles were mediated by their self-efficacy and gameplay anxiety in a competition setting. Data from 112 sixth-grade students were collected for confirmatory factor analysis with structural equation modeling. First, participants completed a trial to familiarize themselves with the functions and mechanism of the game; second, all of the participants were divided into teams to compete against each other for 15 minutes by identifying Chinese paintings; they then completed a questionnaire. The results of this study indicated that FI-CS was positively related to gameplay self-efficacy, but negatively related to gameplay anxiety; perceived utility value could be positively predicted by gameplay self-efficacy, but negatively predicted by gameplay anxiety; and perceived value was positively related to game performance. Moreover, FI-CS was positively related to perceived value mediated by gameplay self-efficacy and gameplay anxiety. The implication of this study is that the Gestalt perception game may engage FI-CS learners with higher levels of gameplay self-efficacy, perceived value, and performance, but a lower level of gameplay anxiety. The present study findings imply that teachers can use Gestalt perception games to promote students’ learning of Taiwanese culture.

An Evaluation of the Relationship Between Perceptions and Performance of Students in a Serious Game

The growing interest in the use of digital games for education resulted in the expansion of the field of game-based learning. There have been several research on the perceptions and attitudes of students towards the use of games for learning. These studies have tried to understand what students make of the use of digital games for learning, as it is believed that the views of users and their acceptance of new technologies play a crucial role in ensuring successful outcomes. However, it is unclear whether there is any relationship between experiences, perceptions towards games and gameplay performance in a learning game. Understanding this relationship is important for game developers to effectively design and develop games, and for educators to be able to determine how to best deploy games for educational purposes. This study examines how the experiences and perceptions of engineering students towards digital games for engineering education influence their use and performance in a serious game called CosmiClean. Findings suggest that while students are enthusiastic about digital learning games, there was no relationship between their perceptions of games for learning and their gameplay performance. However, a relationship was found between the game experiences of students and their gameplay performance.

Improving Monte Carlo Tree Search Policies in StarCraft via Probabilistic Models Learned from Replay Data

Applying game-tree search techniques to RTS games poses a significant challenge, given the large branching factors involved. This paper studies an approach to incorporate knowledge learned offline from game replays to guide the search process. Specifically, we propose to learn Naive Bayesian models predicting the probability of action execution in different game states, and use them to inform the search process of Monte Carlo Tree Search. We evaluate the effect of incorporating these models into several Multiarmed Bandit policies for MCTS in the context of StarCraft, showing a significant improvement in gameplay performance.

An Adversarial Search Method Based on an Iterative Optimal Strategy

A deeper game-tree search can yield a higher decision quality in a heuristic minimax algorithm. However, exceptions can occur as a result of pathological nodes, which are considered to exist in all game trees and can cause a deeper game-tree search, resulting in worse play. To reduce the impact of pathological nodes on the search quality, we propose an iterative optimal minimax (IOM) algorithm by optimizing the backup rule of the classic minimax algorithm. The main idea is that calculating the state values of the intermediate nodes involves not only the static evaluation function involved but also a search into the future, where the latter is given a higher weight. We experimentally demonstrated that the proposed IOM algorithm improved game-playing performance compared to the existing algorithms.

An Automated Mobile Game-based Screening Tool for Patients with Alcohol Dependence

Traditional methods for screening and diagnosis of alcohol dependence are typically administered by trained clinicians in medical settings and often rely on interview responses. These self-reports can be unintentionally or deliberately false, and misleading answers can, in turn, lead to inaccurate assessment and diagnosis. In this study, we examine the use of user-game interaction patterns on mobile games to develop an automated diagnostic and screening tool for alcohol-dependent patients. Our approach relies on the capture of interaction patterns during gameplay, while potential patients engage with popular mobile games on smartphones. The captured signals include gameplay performance, touch gestures, and device motion, with the intention of identifying patients with alcohol dependence. We evaluate the classification performance of various supervised learning algorithms on data collected from 40 patients and 40 age-matched healthy adults. The results show that patients with alcohol dependence can be automatically identified accurately using the ensemble of touch, device motion, and gameplay performance features on 3-minute samples (accuracy=0.95, sensitivity=0.95, and specificity=0.95). The present findings provide strong evidence suggesting the potential use of user-game interaction metrics on existing mobile games as discriminant features for developing an implicit measure to identify alcohol dependence conditions. In addition to supporting healthcare professionals in clinical decision-making, the game-based self-screening method could be used as a novel strategy to promote alcohol dependence screening, especially outside of clinical settings.

Game Running Performance and Fitness in Women's Futsal.

The study aimed to verify possible associations between game-play running performance and outcomes derived from fitness (running) tests in female futsal players. Sixteen women professional elite futsal players from a 1st division league team (19.2±2 years-old, 4.3±2.1 years of experience) participated. Firstly, a graded incremental treadmill test was adopted to determine maximal oxygen uptake (VO2max). Following 72 h of laboratory protocol, players were asked to perform a repeated-sprint test on a court (8×40 m with two 180° change-of-directions). Twenty-four hours after, players participated in a one-off friendly game (two 20-min half-times). A computerized automatic image recognition software (DVIDEOW; 30 Hz) allowed to determine game running performance variables. Fatigue index and best time in the court test and VO2max and its attached speed derived from laboratory-based test showed significant moderate-to-moderately high correlations (r=- 0.59-0.76; p<0.05) with some game running performance outputs, notably related to high-intensity running. In conclusion, the present study provided initial evidence on associations between two fitness tests and one-off game running performance in female futsal. Information derived from the work potentially help conditioning professionals working with female futsal athletes gain awareness about some properties of common testing tools.

Results and Guidelines From a Repeated-Measures Design Experiment Comparing Standing and Seated Full-Body Gesture-Based Immersive Virtual Reality Exergames: Within-Subjects Evaluation.

BackgroundAlthough full-body seated exercises have been studied in a wide range of settings (ie, homes, hospitals, and daycare centers), they have rarely been converted to seated exergames. In addition, there is an increasing number of studies on immersive virtual reality (iVR) full-body gesture-based standing exergames, but the suitability and usefulness of seated exergames remain largely unexplored.ObjectiveThis study aimed to evaluate the difference between playing a full-body gesture-based iVR standing exergame and seated exergame in terms of gameplay performance, intrinsic motivation, and motion sickness.MethodsA total of 52 participants completed the experiment. The order of the game mode (standing and sitting) was counterbalanced. Gameplay performance was evaluated by action or gesture completion time and the number of missed gestures. Exertion was measured by the average heart rate (HR) percentage (AvgHR%), increased HR%, calories burned, and the Borg 6-20 questionnaire. Intrinsic motivation was assessed with the Intrinsic Motivation Inventory (IMI), whereas motion sickness was assessed via the Motion Sickness Assessment Questionnaire (MSAQ). In addition, we measured the fear of falling using a 10-point Likert scale questionnaire.ResultsPlayers missed more gestures in the seated exergame than in the standing exergame, but the overall miss rate was low (2.3/120, 1.9%). The analysis yielded significantly higher AvgHR%, increased HR%, calories burned, and Borg 6-20 rating of perceived exertion values for the seated exergame (all P<.001). The seated exergame was rated significantly higher on peripheral sickness (P=.02) and sopite-related sickness (MSAQ) (P=.004) than the standing exergame. The score of the subscale “value/usefulness” from IMI was reported to be higher for the seated exergame than the standing exergame. There was no significant difference between the seated exergame and standing exergame in terms of intrinsic motivation (interest/enjoyment, P=.96; perceived competence, P=.26; pressure/tension, P=.42) and the fear of falling (P=.25).ConclusionsSeated iVR full-body gesture-based exergames can be valuable complements to standing exergames. Seated exergames have the potential to lead to higher exertion, provide higher value to players, and be more applicable in small spaces compared with standing exergames. However, gestures for seated exergames need to be designed carefully to minimize motion sickness, and more time should be given to users to perform gestures in seated exergames compared with standing exergames.
