Health literacy after traumatic brain injury: characterisation and control comparison.

Background Little is known about health literacy in traumatic brain injury (TBI) survivors. The aims of this study were to compare health literacy in individuals with TBI with that of a control group; to examine the association between health literacy in individuals with TBI and demographic, injury, and cognitive factors; and compare the relationship between health literacy and physical and mental health outcomes. Methods A cross-sectional observational study design was used. Adults (≥18years) were recruited from an outpatient research centre in Victoria, Australia. There were 209 participants with a complicated mild to severe TBI at least 1year previously (up to 30years 6months) and 206 control participants. Results Individuals with TBI did not have poorer health literacy than controls (IRR=1.31, P =0.102, CI95% [0.947, 1.812]). Further analysis could not be completed due to the highly skewed Health Literacy Assessment Using Talking Touchscreen Technology - Short Form (Health LiTT-SF) data. Conclusion Health literacy performance in individuals with TBI was not significantly different to controls. Premorbid education may provide a critical cognitive reserve upon which TBI survivors can draw to aid their health literacy. These findings are specific to the Health LiTT-SF measure only and require replication using more comprehensive health literacy measures in culturally diverse samples.

Embedded real-time ultrasound-based multi-touch system.

In this paper, an active ultrasound-based touchscreen technology is presented for real-time monitoring of multiple contacts on a glass panel of 20 × 19 cm. Both fundamental Lamb wave modes are generated by sending a linear chirp between 50 and 100 kHz to a single piezoelectric ceramic lead zirconate titanate. Measurement is performed using four piezoelectric ceramic lead zirconate titanate elements, and real-time localization and detection are performed on a system on module i.MX 8 M Nano. Results show that Lamb waves can be used for real-time multi-touch detection and localization on both sides of the panel. Moreover, the prototype developed allows for relative pressure measurement.

Chronic ecologically relevant stress effects on reverse-translated touchscreen assays of reward responsivity and attentional processes in male rats: Implications for depression.

Stagnation in the development of novel therapeutic strategies for treatment-resistant depression has encouraged continued interest in improving preclinical methods. One tactic prioritizes the reverse translation of behavioral tasks developed to objectively quantify depressive phenotypes in patient populations for their use in laboratory animals via touchscreen technology. After cross-species concordance in task outcomes under healthy conditions is confirmed, construct validity can be further enhanced by identifying environmental stressors that reliably produce deficits in task performance that resemble those in depressive participants. The present studies characterized in male rats the ability of two chronic ecologically relevant stressors, inescapable ice water or isolated restraint, to produce depressive-like behavioral phenotypes in the Probabilistic Reward Task (PRT) and Psychomotor Vigilance Task (PVT). These tasks previously have been reverse-translated using touchscreen technology for rodents and nonhuman primates to objectively quantify, respectively, reward responsivity (anhedonia) and attentional processes (impaired cognitive function), each of which are core features of major depressive disorder. In the PRT, both inescapable ice water and isolated restraint produced persistent anhedonic phenotypes compared to non-stressed control performance (i.e., significantly blunted response bias for the richly rewarded stimulus). In the PVT, both chronic stressors impaired attentional processing, revealed by increases in titrated reaction times; however, these deficits largely subsided by the end of the chronic condition. Taken together, these findings confirm the ability of reverse-translated touchscreen tasks to effectively generate behavioral phenotypes that exhibit expected deficits in performance outcomes following exposure to chronic ecologically relevant stress. In turn, this approach is well positioned to appraise the ability of candidate therapeutics to attenuate or reverse such behavioral deficits and, thereby, contribute to preclinical medications development for treatment-resistant depression.

Chinese early childhood educators’ beliefs and experiences around using touchscreens with children under three years of age

ABSTRACT Research shows that educators’ technology beliefs and experiences strongly shape their technology adoption and utilization in educational practices. This mixed-method study investigated very young children’s educators’ touchscreen use and their beliefs and experiences in China. Rich quantitative findings (N = 1276) revealed the availability of touchscreen devices mainly computers and laptops in early childhood educational settings and this technology provision aligns with Chinese traditional teacher-centred educational practices. Despite their highly reported digital skills, educators’ overall use of touchscreen technologies with very young children was low and there was a lack of confidence in using them with children. It appears that confidence is more influential for Chinese educators in deciding to use technology with very young children than their digital skills. Implications for educational policies and designing effective professional learning and development for early childhood educators to enhance their digital competence are discussed.

The research of touch screen usability in civil aircraft cockpit.

With the advancement of touch screen technology, the application of touch screens in civil aircraft cockpits has become increasingly popular. However, further analysis and research are required to fully promote its applications. The paper researched the usability of touch screens in aircraft cockpit considering the operation performance and subjective NASA-TLX workload evaluation, conducted experimental research on three touch gestures: click, drag, and zoom. Additionally, a comparative analysis was conducted on the touch performance under different layouts, positions, touch sizes, dragging direction angles, and zoom multiples. The touch performance indicators include operation time, error rate, operation speed, and workload. The experimental results show that the 21 mm size has the minimum operation time and workload, and 18 mm size has the lowest error rate in the clicking tasks. Additionally, the performance and workload of the captain's layout are better than those of the co-pilot's layout, and the performance of the center console position is best. The operation speed of the dragging tasks is faster when performed at position R3 compared to other positions. The dragging moving angles with better operation speed are 80°-190° and 250°-290°. The operation performance and workload of the zooming tasks vary depending on the zoom multiples. As the multiple increases, the operation time and workload also increase. There is no difference in operation performance or workload between zooming in and zooming out. The paper provides experimental support and suggestions based on human operation and subjective NASA-TLX workload evaluation for the application of touch screens in civil aircraft cockpits.

Adapted Home-Based Exercises in Dementia: An Exploratory Pre-post Pilot and Feasibility Study.

The goals of this exploratory pre-post pilot and feasibility study (NCT04916964) were to assess the feasibility and effectiveness of an adapted Test-and-Exercise home-based exercise program on basic functional mobility and executive functions in persons with prodromal or mild Alzheimer's disease. Participants followed an 8week exercise program at home, once per week with a physiotherapist and twice per week with their usual caregiver or independently. Functional mobility and executive functions were assessed before and after the intervention. Feasibility criteria were recruitment opportunity, participation agreement rate, cost adequacy, and drop-out rate. Twelve participants aged 80.83 ± 4.65years took part in the study. All the basic functional mobility measures showed small effect sizes. Concerning executive functions, 5 measures showed small to moderate effect sizes. The 4 feasibility criteria were met. A larger scale study would, however, need adaptations and prior research on the ability of this population to use touch-screen technology.

The advantages and comparison of resistive touch screens and capacitive touch screens

ATouch screens are an indispensable component in electronic products nowadays, and resistive and capacitive touch screens are the most common and widely used touch screens in touch screens. However, there is still a lack of intuitive literature to explain the differences and advantages between capacitive and resistive touch screens. This article provides a partial overview of the principles and structures of resistive and capacitive touch screen technologies and finally analyzes their respective advantages and disadvantages. The resistive touch screen is mainly divided into four-wire resistive touch screens and five-wire resistive touch screens. Its advantage over capacitive touch screens is that the process is more mature, and the product cost is lower. However, capacitive touch screens, due to their different working principles from resistive touch screens, can achieve multi-point touch, which is a significant feature. In capacitive touch screens, mutual capacitive projection capacitive touch screens have become the main favored technology in the touch screen industry due to their low power consumption, stable signal, and fast data collection speed. They are also an essential direction for the future development of touch screens.

Capturing Movement: A Tablet App, Geometry Touch, for Recording Onscreen Finger-Based Gesture Data

This paper presents a novel digital method of capturing finger-based gestures on touchscreen devices for the purposes of exploring tracing gestures in educational research. Given that tracing has been found to support cognition, learning and problem-solving in educational settings, data related to the performance of these gestures is increasingly of interest to researchers. Most educational research methods exploring the use of hand gestures rely on in-person data collection, whether through direct observation, or video recording of participants' behaviour for later analysis. These methods, while effective for observing gross movements, may not provide researchers with detailed insights into how learners interact with learning materials. Using custom tools to record touchscreen engagement on tablet computing devices can address this limitation, while also providing the means to visually represent touch-based interactions with these devices. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Geometry Touch</i> is an iPad app developed and tested by the primary author as part of a pilot study. The research study, theoretically grounded in Cognitive Load Theory, demonstrated that <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Geometry Touch</i> could efficiently collect data on touchscreen interactions, while also providing potential avenues to quantify touchscreen interactions through computational means. The purpose of this paper is to report on the development and testing of this app, while providing an explanation of how it was used as a method of data collection by leveraging touchscreen technology. The paper concludes by discussing how this digital method of capturing movement can provide further insight into how finger-based gestures can influence learning and as such, could increase the reach of gesture-based research.

Examining the Feasibility and Acceptability of Digital Cognitive Stimulation Therapy for Dementia Care in Jordan: A Qualitative Study.

The use of technology to deliver psychosocial interventions such as cognitive stimulation therapy (CST) to individuals with dementia may improve their cognition and quality of life. This study aimed to investigate the participants' experiences with digital CST in Jordanian care homes, as well as the acceptability of the digital CST intervention in Jordanian care homes and recommendations for refinement. A qualitative study design and semistructured interviews were used to obtain data from 20 people with dementia and 12 care home staff who were purposefully selected. Data were analyzed thematically and comparatively to explore the experiences and outcomes of the participants. This study was conducted from February to April 2023. Analysis of care home staff and residents' experiences revealed seven major themes: (a) personalized support and engagement, (b) positive impact on quality of life, (c) engagement and meaningful activities, (d) adaptable format and accessibility, (e) emotional connection and empowerment, (f) caregiver involvement and support, and (g) suggestions for improvement. The study's findings emphasize the necessity of tailored support, individualized difficulty levels, individualized material selection, emotional support, greater social connection, and caregiver participation in digital CST for people with dementia. Using digital touchscreen technology to deliver CST content has shown potential improvements, making interventions simpler for staff and more beneficial for individuals with dementia, thereby enhancing cognition and quality of life.

Improving Parents' Ability To Control Gadget Usage Among Children In Pre-School

Abstract. TK (Kindergarten) ABA Patukan conducted its online instruction using a variety of platforms throughout the Covid-19 Pandemic. The fact that children are particularly interested in today's technology is not incorrect. This is because modern technology has developed into a highly attractive object with an attractive appearance that also uses touchscreen technology to further its attractiveness. There are concerns associated with using technology for online learning for students' kids. Parents frequently complain to teachers that their kids are getting out of hand and refuse to do schoolwork if they can't use devices or play online games, and they also throw tantrums. Parents and teachers have never received health education about the mental health of preschoolers, particularly regarding the risks associated with gadget use in kids and how to regulate the growth and development of preschoolers. The solutions proposed include gadget addiction screening, child growth and development monitoring, health counselling regarding the risks of gadget addiction in kids, and teaching regarding the development of preschoolers. The majority of students' screening results for gadget addiction fell into the low category (51%); similarly, the majority of children's screening results for growth and development are age-appropriate (61%), and parental knowledge of how to manage gadgets for kids has increased from 69.74 to 77.71.

A Mixed Methods Approach to Analyzing Embodied Interaction: The Potentials of Integrated Mixed Methods Analysis of Video Interaction Data

Video has become a widespread tool for capturing naturalistic behavioral data. While mixed methods show great potential in understanding the active nature of children’s interaction, only a few studies have developed mixed methods for video-based interaction research. This paper presents a mixed methods embodied interaction model appropriate for studying complex embodied interaction and draws on methodological insights from a mixed methods project to capture changes in children’s interaction with touchscreen technologies. The paper details how integrated mixed methods analysis was needed to fully explain the results and how mono-method studies would provide misleading results. The theoretical advancements generated during the project illustrate how mixed methods for video-based studies have valuable properties for understanding complex interactional phenomena, such as learning.

Touching Disney: Loneliness and Sources of Comfort in the Digital Age

Reflecting on moving image affect and human-computer interaction, the following paper considers the connections between elective states of loneliness and different spectatorship habits, including excessive media consumption and escapism into nostalgic media texts. Comparing the experience of communal spectatorship fostered by the space of the cinema in the early twentieth century to the accessibility and endless choice of moving image content facilitated by streaming platforms, it also considers the cultural value and the status of moving image as a manifestation in the world. Drawing on examples from streaming platforms' content, and especially the model provided by Disney Plus, the following exploration illustrates the transformation of familiar media texts into emotionally charged objects of nostalgia, agents of deeply rooted childhood memories, and often, sources of comfort. Their presence on handheld devices facilitates new forms of engagement, including repetitive viewing, tactility and increased levels of intimacy and interactivity through the nature of touchscreens, including holding, scrolling, pinching, swiping and other performative gestures. Drawing on existing definitions of loneliness and emerging theories of audience engagement with touch-screen technologies, this paper considers practices of repetitive watching and binge-watching, new forms of viewing familiar content, as well as the spectators' historic relationship to Disney content, as responses to loneliness triggered by emotional or social isolation.

Unveiling the Nexus: Disentangling the Impact of Touch Screen Frequency in Electronic Media on Amplifying Control Perception, Elevating Psychological Ownership, and Igniting Intentions to Reuse Payment Services

This study explores the impact of touch screen technology on users’ sense of control and psychological ownership of electronic payment services. Through an examination of the influence of touch interface during transactions, this study investigates how enhancing feelings of influence and authority can increase motivation to reuse payment services. Dual surveys were conducted, revealing that increased touch input for the transaction amount enhances feelings of influence, which in turn augments the sense of authority. Additionally, the study found that the sense of belonging resulting from panel touch increases motivation for repeat transactions.

Characterizing touchscreen actions in technology-enhanced embodied learning for mathematics instruction in K-12 setting – A systematic review (2010–2023)

Touchscreen devices have become prominent in a variety of educational contexts due to their use of hands-on and interactive learning styles, and particularly for their direct engagement, rapid orientation, and multi-touch affordances, which textbooks and oral instruction may not always provide. As such, over the past decade, both the number of touchscreen applications for mathematics learning and the body of research examining their efficacy have increased. Yet, there are still few existing systematic reviews of how these touchscreen-based mathematics applications promote K-12 student learning. In response, this paper provides an in-depth examination of extant studies which adopt practices that utilize touchscreen technology for K-12 mathematics teaching and learning. The Web of Science database was searched for research published between 2010 and 2023, and 34 papers were chosen to review the empirical bases of touchscreen-based mathematics learning. These articles were analyzed based on the educational contexts found, touchscreen actions prompted, and the mathematical meanings elicited from these actions. Most significantly, we propose a touchscreen action matrix that characterizes the actions performed on the touchscreen platform and presents the mathematical meanings derived from these action categories. We hope that this review and characterization provide guidance for researchers, designers, and educators in eliciting mathematical knowing with action-based design in touchscreen medium.

Virtual Mouse Operations Using Webcam

With new changes seen in computer technology day by day, it has become quite essential for us to find specific new ways of interaction with computer systems as its need is increasing in society every day. Today, every device is making the use of touch screen technology on its systems, which isn't affordable to be used in all applications. A specific interactive module like a virtual mouse that makes use of Hand Tracking and Gestures that will help us to interact can be an alternative way for the traditional touch screen and the physical mouse. The objective is to create a Hand Tracking application that interacts with the system. This system proposed is a Computer Vision-based mouse cursor control system, which uses hand gestures that are being captured from a webcam through a Hand detection technique. This system allows the user to navigate the system cursor using their hand gestures that the computer webcam tracks and perform mouse operations like left- click, right-click, and double click using different hand gestures. Python and OpenCV library are used for real- time computer vision to implement the system. The camera output is displayed on the monitor.

Dynamic virtual assistance of I/O functionalities

With significant advancements being witnessed in the engineering industry daily, it has become increasingly vital for society to seek out particular new ways of interacting with computer technology and automation as their demand grows in society. Today, every device is developing the use of touch screen technology on its computer systems, although it is not cost-effective to use in all applications. A specialized system, similar to a virtual device, that provides object pursuit (tracking) and Gestures to let us engage; it might be an effective alternative to the standard touch screen and also the solid physical gadgets. The goal is to create an object pursuit (tracking) program that communicates with the computer system. This proposed model is a computer vision-based control system that involves hand movements taken from a digital camera via a hand detection technique implemented with OpenCV libraries. Our project applies gesture recognition as a topic that comes under two computer science fields augmented reality and human-computer interaction and we have created a virtual gesture system to elucidate human gestures through mathematical algorithms. Users can use simple finger or hand gestures to control or interact with the system without physically touching them and also included voice assistance to start and end the gesture controlling system. Gesture recognition can be viewed as a way for computers to begin to recognize human body language and signs, thus stuffing the void between computing systems and humans than the earliest text user interfaces or even graphical user interfaces, which still limit the majority of input to keyboard and mouse are may not be very efficient at all times. The algorithm is focused on deep learning for detecting the gestures. Hence, the proposed system will avoid the pandemic situation of COVID-19 spread by reducing the human interaction with the devices to control the system

Supporting people living with dementia in novel joint activities: Managing tablet computers

A bourgeoning number of studies have demonstrated that people living with dementia are capable of participating in a wide range of everyday activities when supported by care professionals or family carers. However, little remains known about the situated practices used by carers to support people living with dementia as active co-participants in novel joint activities. Taking the use of tablet computers as an example, this study focuses on the interactional organization of instructions in joint activities involving people living with dementia, who have no previous experiences of touchscreen technologies, and their carers. The study is based on forty-one video recordings of ten dyads, each comprising a person living with dementia and a carer, as they are using tablet computers with applications suited to individual interests. Drawing on multimodal interaction analysis, we show how the carers continually foster the accomplishment of their interlocutors, and rarely take over responsibility for closing an ongoing joint project themselves. Our findings suggest that the carers' instructions, realized as verbal and embodied directives, function as a form of scaffolding practice that facilitates the coordination of visual perception and embodied conduct for the participants living with dementia.

Lab cognition going wild: Implementing a new portable touchscreen system in vervet monkeys.

Touchscreen technology has provided researchers with opportunities to conduct well-controlled cognitive tests with captive animals, allowing researchers to isolate individuals, select participants based on specific traits, and control aspects of the environment. In this study, we aimed to investigate the potential utility of touchscreen technology for the study of cognition in wild vervet monkeys. We assessed the viability of touchscreen testing by comparing rates of participation between wild and sanctuary-housed vervets. Additionally, we compared performance on a simple associative learning task in order to verify that wild participants are able to engage meaningfully with a touchscreen task presented in their natural environment. We presented eight groups of vervet monkeys (four wild and four sanctuary groups, totalling 240 individuals) with a portable touchscreen device. The touchscreen displayed tasks in which food rewards could be gained by touching a stimulus displayed on the screen. We assessed individuals' likelihood of interacting with the touchscreen, their frequency of participation, and their performance on a simple associative learning task. We found that sanctuary-housed monkeys were more likely to interact with the touchscreen. Participation in wild vervet monkeys was influenced by sex and age. However, monkeys in the two contexts (sanctuary vs. wild) did not differ in their performance on a simple associative learning task. This study demonstrates that touchscreen technology can be successfully deployed in a population of wild primates. This gives us a starting point to test animal cognition under natural conditions that include varying group composition, environmental challenges and ongoing activities such as foraging, which are challenging to recreate in captivity. While rates of participation were lower than those found in captivity, reasonable sample sizes can be achieved, and wild primates can successfully learn touchscreen tasks in a manner comparable to their captive counterparts.
