Factors Affecting Customer Satisfaction and Loyalty in Online Food Delivery Service during the COVID-19 Pandemic: Its Relation with Open Innovation

Online food delivery service (OFDS) has been widely utilized during the new normal of the COVID-19 pandemic, especially in a developing country such as Indonesia. The purpose of this study was to determine factors influencing customer satisfaction and loyalty in OFDS during the new normal of the COVID-19 pandemic in Indonesia by utilizing the extended theory of planned behavior (TPB) approach. A total of 253 respondents voluntarily participated and answered 65 questions. Structural equation modeling (SEM) indicated that hedonic motivation (HM) was found to have the highest effect on customer satisfaction, followed by price (P), information quality (IQ), and promotion (PRO). Interestingly, this study found out that usability factors, such as navigational design (ND) and perceived ease of use (PEOU) were not significant to customer satisfaction and loyalty in OFDS during the new normal of COVID-19. This study can be the theoretical foundation that could be very beneficial for OFDS investors, IT engineers, and even academicians. Finally, this study can be applied and extended to determine factors influencing customer satisfaction and loyalty in OFDS during the new normal of COVID-19 in other countries.

Mini-Map for Gamers Who Walk and Teleport in a Virtual Stronghold

Studies of the effectiveness of multimedia cartography products may include mini-map design for navigation. In this study, we have touched upon designing gameplay to indicate the impact of the mini-map on the time effectiveness of a player that can walk or teleport himself/herself along marked out points in virtual topographic space. The eye-tracking examination of gamers’ effectiveness in a non-complex game of collecting coins in a reconstructed stronghold on the holm provided us with a new perspective on the role of mini-maps. The more time gamers took to examine the mini-map, the more time they needed to finish the game, thus decreasing their effectiveness. The teleporting gamers had significantly higher time effectiveness than walking gamers, however, the data obtained showed only a minor difference between the proportions of the mini-map examination time to the total game time for walking and teleportation.

Tablets for problem-solving through a flow theory: the impact of navigation and visual appearance on perceived performance and efficiency

PurposeThe paper aims to investigate how a tablet's design features, namely, its navigation design and visual appearance, influence users' enjoyment, concentration and control, when using tablets for problem-solving, and thereafter how their core flow experiences impact their perceived performance and efficiency with problem-solving.Design/methodology/approachThis study uses a field survey approach to engage 87 participants in a decision sciences class to use eTextbooks and a few other associated educational apps including CourseSmart app for e-notes and highlighting, sketchbook app and a calculator app in tablets to resolve class problems at a large US university.FindingsThis study finds that the tablet's interface design features (navigation and visual appearance) make users engrossed in their problem-solving processes with perceived enjoyment, concentration and control.

More in-depth user flow experience design associated with tablet use for problem-solving contexts should be further advocated in order to provide more engaging and meaningful flow experiences to users.Originality/valueThis study shows that the design of the tablet interface can engage users in problem-solving processes in both affective and cognitive ways. It provides valuable insights on tablet interface design for problem-solving.

FEATURES OF BOUNDARY ELEMENT METHOD APPLICATION FOR SOLUTIONS OF BOUNDARY-VALUE PROBLEMS IN MOVING BOUNDARY DOMAINS

Summary. The motion of a fluid with a free surface is the subject of a separate section of theoretical hydromechanics. The development of this direction is stimulated by numerous applications to modern technologies, especially for the design and operation of hydraulic structures, shipbuilding and navigation, the study of ebbs and flows, tsunamis and other natural phenomena. The complexity of setting and solving this class of problems lies in the presence of a moving boundary of the solution area, called the free surface. From a mathematical point of view, the peculiarity of the considered class of problems lies in a specific non-linearity: a solution-dependent change in time of the shape of the solution area. Assuming the fluid to be incompressible and in viscid, under the conditions of the potentiality of the field of body forces and the potentiality of the flow at the initial moment of time, we obtain that the flow is described by the Laplace equation for the velocity potential with the traditional boundary conditions of non-flow at the solid boundaries of the flow region, as well as special boundary conditions at the free boundary, one of which, the Cauchy-Lagrange integral, contains a quadratic nonlinearity in the flow velocity. The assumption made about the potentiality of the alternating field of body forces greatly simplifies the formulation of the problem and allows us to consider the problem formulated above as a model one for a wide class of fluid flows with a free surface. For the numerical solution of the problem described above, a regular version of the boundary element method was used. The use of regular algorithms of the boundary element method makes it possible to bypass numerous computational limitations and improve in one way or another the approximations of the shape of the moving boundary, known and unknown functions on it. To do this, the Laplace equation was transformed into a boundary integral equation of potential theory, and the time interval in which the flow field is studied was divided into the corresponding number of sufficiently small intervals. At each time step, the resulting boundary integral equation was solved using the standard algorithm of the boundary element method. The calculation of the new position of the free boundary of the flow was carried out using the Euler scheme.

Navigation Design and Library Terminology

The University Library at California State University, Stanislaus is not only undergoing a library building renovation, but a website redesign as well. The library conducted a user-centered usability study to collect data in order to best lead the library website “renovation.” A prototype was created to assess an audience-based navigation design, homepage content framework, and heading terminology. The usability study consisted of 38 student participants. It was determined that a topic-based navigation design will be implemented instead of an audience-based navigation, a search-all search box will be integrated, and the headings and menu links will be modified to avoid ambiguous library terminology. Further research on different navigation and content designs, and usability design approaches, will be explored for future studies.

Research and verification of the autonomous navigation technology of GNSS

This paper discusses the important role of autonomous navigation capability in the development of Global Navigation Satellite Systems (GNSS) based on the current status of major GNSS designs. The architecture design for autonomous navigation by a GNSS, mainly comprising the system composition and operational process, is discussed in detail. The key technology that maintains the time and spatial reference of an autonomous navigation system is also discussed. This paper then studies the filtering algorithm, the filtering state noise covariance matrix, and the processing method of satellite-borne data based on inter-satellite observations. It also proposes a semi-autonomous navigation method based on ground observation data (anchor stations), and compares the performances of automatic navigation with different layouts and numbers of anchor stations and different observation periods. The autonomous navigation performance was evaluated in a ground-simulation test system under different GNSS deployment stages and operation modes. The accuracy of orbit determination and time synchronization of GNSS were then verified in fully autonomous and semi-autonomous navigation modes. The results provide an important reference for automating the navigation service of GNSS.

Natural Interaction Design for Navigation in Virtual Environment of Sino-Portuguese Architecture in Museum

Virtual Environment (VE) is an artificial environment created for providing the information in Virtual Reality (VR). The audiences are able to obtain the information via interaction to the environment. Virtual Reality for Culture heritage buildings, which are inherited from past generations and maintained in the present, is an interested topic because its contents often built for giving the information and knowledge about the past to the new generation in virtual museums. However, there is a limitation of Virtual Reality (VR) applications in reproducing cultural sites as most of these applications are not successful in catching public’s attention and involvement. In this research, we focus on using Natural Interaction (NI) interfaces based on a body movement in Virtual Reality for museums to grab attention from audience and to increase public’s involvement. This paper presents the development of Natural Interaction using Microsoft Kinect to define the new grammar of gesture for Sino Portuguese Architecture which is a cultural heritage of Thailand. Results of early tests improved the prototype in progress which alllows more complexity in natural interchanges and connection between users and virtual world. The final result was evaluated after the system was installed in Peranakannitat museum and by interviewing 6 docents. It was found that our system was easy to use as it took only about 3 - 5 min to familiarize the system for navigation in the virtual environment without recognizing the grammar of gesture commands.

A Submillimeter Level Relative Navigation Technology for Spacecraft Formation Flying in Highly Elliptical Orbit.

Spacecraft formation flying (SFF) in highly elliptical orbit (HEO) has attracted a great deal of attention in many space exploration applications, while precise guidance, navigation, and control (GNC) technology—especially precise ranging—are the basis of success for such SFF missions. In this paper, we introduce a novel K-band microwave ranging (MWR) equipment for the on-orbit verification of submillimeter-level precise ranging technology in future HEO SFF missions. The ranging technique is a synchronous dual one-way ranging (DOWR) microwave phase accumulation system, which achieved a ranging accuracy of tens of microns in the laboratory environment. The detailed design and development process of the MWR equipment are provided, ranging error sources are analyzed, and relative orbit dynamic models for HEO formation scenes are given with real perturbations considered. Moreover, an adaptive Kalman filter algorithm is introduced for SFF relative navigation design, incorporating process noise uncertainty. The performance of SFF relative navigation while using MWR is tested in a hardware-in-the-loop (HIL) simulation system within a high-precision six degrees of freedom (6-DOF) moving platform. The final range estimation errors from MWR using the adaptive filter were less than 35 m and 8.5 m/s for range rate, demonstrating the promising accuracy for future HEO formation mission applications.

A review of algorithms and techniques for image-based recognition and inference in mobile robotic systems

Autonomous vehicles include driverless, self-driving and robotic cars, and other platforms capable of sensing and interacting with its environment and navigating without human help. On the other hand, semiautonomous vehicles achieve partial realization of autonomy with human intervention, for example, in driver-assisted vehicles. Autonomous vehicles first interact with their surrounding using mounted sensors. Typically, visual sensors are used to acquire images, and computer vision techniques, signal processing, machine learning, and other techniques are applied to acquire, process, and extract information. The control subsystem interprets sensory information to identify appropriate navigation path to its destination and action plan to carry out tasks. Feedbacks are also elicited from the environment to improve upon its behavior. To increase sensing accuracy, autonomous vehicles are equipped with many sensors [light detection and ranging (LiDARs), infrared, sonar, inertial measurement units, etc.], as well as communication subsystem. Autonomous vehicles face several challenges such as unknown environments, blind spots (unseen views), non-line-of-sight scenarios, poor performance of sensors due to weather conditions, sensor errors, false alarms, limited energy, limited computational resources, algorithmic complexity, human–machine communications, size, and weight constraints. To tackle these problems, several algorithmic approaches have been implemented covering design of sensors, processing, control, and navigation. The review seeks to provide up-to-date information on the requirements, algorithms, and main challenges in the use of machine vision–based techniques for navigation and control in autonomous vehicles. An application using land-based vehicle as an Internet of Thing-enabled platform for pedestrian detection and tracking is also presented.

User-centered system design for assisted navigation of visually impaired individuals in outdoor cultural environments

The marginalization of people with disabilities, such as visually impaired individuals (VIIs), has driven scientists to take advantage of the fast growth of smart technologies and develop smart assistive systems (SASs) to bring VIIs back to social life, education and even to culture. Our research focuses on developing a human–computer interactive system that will guide VIIs in outdoor cultural environments by offering universal access to cultural information, social networking and safe navigation among other services. The VI users interact with computer-based SAS to control the system during its operation, while having access to remote connection with non-VIIs for external guidance and company. The development of such a system needs a user-centered design (UCD) that incorporates the elicitation of the necessary requirements for a satisfying operation for the VI users. In this paper, we present a novel SAS system for VIIs and its design considerations, which follow a UCD approach to determine a set of operational, functional, ergonomic, environmental and optional requirements of the system. Both VIIs and non-VIIs took part in a series of interviews and questionnaires, from which data were analyzed to form the requirements of the system for both the on-site and remote use. The final requirements are tested by trials and their evaluation and results are presented. The experimental investigations gave significant feedback for the development of the system, throughout the design process. The most important contribution of this study is the derivation of requirements applicable not only to the specific system under investigation, but also to other relevant SASs for VIIs.

Background. Provided stronger demands of people towards healthcare systems, changes in the legal framework and increasing competition, medical institutions are seeking new approaches and mechanisms for improving comfort of medical care services. Navigation support as part of the visualisation system in a medical unit should comply with certain standards of colour design and its comfortable presentation to patients.Objectives. To formulate basic principles for effective colour navigation support in medical facilities using best national and foreign practices of colour design for navigation and visualisation solutions in healthcare.Мethods. Relevant publications were mined in Scopus, Web of Science, MedLine, the Cochrane Library, Elibrary and PubMed. Search depth by time was limited to 10 years. Main keyword queries were «lean production» [«бережливое производство»], «lean healthcare» [«бережливое здравоохранение»], «lean medicine», «navigation» [«навигация»], «visualization» [«визуализация»], «бережливая поликлиника», «квалиметрия». The obtained data were interpreted using legal, historical, descriptive analytical methods, content analysis.Results. Colour solutions in the Russian healthcare system are implemented in a variety of ways to support data visualisation. As part of a visual and tactile navigation system, the colour solutions serve to highlight individual navigation objects, pattern space, order and structure navigation elements, emphasise and manage relevant textual information. Incorrect colour navigation support can lead to wastes of lean principles in the main, auxiliary and maintenance processes in a medical facility. The Russian federal legislation does not currently regulate colour solutions for visualisation support in medical institutions.Conclusion. Colour solutions being part of navigation support systems should be regulated by federal and regional legal acts to allow qualimetric assessment and improvement of navigation and visual systems in medical facilities. A high-quality design of navigation support requires detailed information about the managed institution.

State of the Science of Dimensions of Nurses' User Experience When Using an Electronic Health Record.

This integrative review synthesized relevant studies in the last decade associated to nurses' experience with the electronic health record using Robert and Lesage's dimensions of User Experience: functional, physical, perceptual, cognitive, psychological, and social. A comprehensive search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance across four electronic databases. We included articles if they were specific to nurses' electronic health record experience and workflow, published between January 2008 and June 2018, and available in English. The search resulted in 793 records with 26 articles included in the final analysis. Articles ranged from quantitative, qualitative, mixed-methods, and quality improvement studies. Across studies, the suboptimal design of the electronic health record affected the functional experience of nurses, often resulting in interruptions. The navigational design contributed to nurses' perceptual experience leading to many workarounds and workflow mismatches. Most of the studies reported overall satisfaction with the electronic health record that represented the psychological dimension of nurses' experience. Communication barriers due to the use of the electronic health record prevented nurses from having meaningful interaction with other clinicians and patients. Although nurses reported substandard user experience, many stated that reverting to a linear paper-based system was not an option.

Secure communication system in maritime navigation using state observer with linear matrix inequality

ABSTRACT With emerge of smart navigation, the secure communication issues have drawn extensive attention on maritime agendas between ships or with the shore. This paper presents a chaotic secure communication scheme by using observer design for maritime navigation and transportation systems. The proposed scheme involves three key factors: chaotic encryption, state observer, and chaotic decryption. The chaotic system, as the encryption keys carrying confidential information, will be sent from transmitter to the receiver through a public channel. It is obvious that the fewer signals are transmitted on the public channel, the higher security of the communication system is possible. A state observer is designed to estimate all system states when only partial states are detectable on the public channel. The robust observer gain is implemented in terms of linear matrix inequality (LMI) for convex optimization. The process of information encryption and recovery has been discussed in detail. From the simulation results, it is found that the observer-based method can robustly estimate full state variables by using system output signals with LMI optimization. Based on these updated states with the the state observer, the original information is accurately recovered for safe navigation of vessels with reliability and efficiency.

성학십도 VR: 융합 연구를 통한 가상의 철학적 사유 공간 디자인

Our society is confronting a new technological revolution. This revolution will change the way we live and work. A true understanding of humanity and human beings will aid in the development of a better co-existing human-technology relationship. In this study, we attempted to foster an understanding humanity based on the perspective of Toegye Yi Hwang’s Ten Diagrams on Sage Learning, called Sunghaksipdo in Korean. From its inception, Virtual Reality has been distinctly effective at providing immersive perspective-taking experiences. However, for this project, we focused on the use of a VR-enhanced environment as an introspective tool. To accomplish this, we constructed a transdisciplinary study by creating a Ten Diagrams on Sage Learning virtual reality environment, called Sunghaksipdo VR. The purpose of this study is to explore technological opportunities for cultivating a public understanding of Neo-Confucianism by creating “Taegukdo”, the first diagram in the Ten Diagrams on Sage Learning. First, we examined three background theories: Neo-Confucianism, virtual reality for the Ten Diagrams on Sage Learning, and spiritual experience. Then, with a deep understanding of these theories, we designed and developed the Sunghaksipdo VR. The major principle we followed was the HMD-based VR Environment design process. Specifically, we conducted the design process in two phases to create appropriate content, then administered a pilot user study with our first prototype. This pilot study had two main purposes: to evaluate user content comprehension and overall user experience. In brief, the results showed that the content creation was quite successful. Most users were very satisfied with this introspective VR experience, and they also wanted to see more content related to Eastern philosophical thought through this kind of vivid visualization. When it comes to user experience, we still need to improve some navigation design features and propose better ideas to decrease VR use-associated physical fatigue. Ultimately, we hope to use VR technology to provide users spiritual experiences.
