“… Error rate: the number of errors/mistakes committed during all tasks.  Usability: participants were asked to complete a modified version of the Telehealth Usability Questionnaire (TUQ) [23,24]. The TUQ is a qualitative survey covering six factors -usefulness, ease of use and learnability, interface quality, interaction quality, reliability, satisfaction and future use [23,24].…”

Background: A mobile health system called iMHere (interactive Mobile Health and Rehabilitation) was developed to support individuals with chronic conditions and disability in their self-management regimens. The initial design of iMHere, however, lacked sufficient accessibility for users with a myriad of dexterity impairments. The accessibility of self-management apps is essential in ensuring usability. Objective: This study aims to increase the usability of the iMHere system for users with dexterity impairments by increasing the app's accessibility. Methods: We targeted accessibility redesign by focusing on the physical presentation and the navigability of the iMHere apps. Six participants presenting with dexterity impairments were included in the usability study of the original and redesigned apps. Results: We report a trend toward a lower number of touches needed to complete tasks (p=0.088) and time to complete individual tasks (p=0.057) in the redesigned app compared to the original app. Significantly lower time for users to complete all tasks (p=0.006) and significantly lower error rate (p=0.013) was seen with use of the redesigned app compared to the original app. In fact, no errors occurred with use of the redesigned app. Participant-reported overall average usability of the redesigned app (p=0.007) and usability of individual modules (p<0.001) were significantly higher than that of the original app due mostly to better ease of use and learnability, interface quality, and reliability. Conclusion: Improved usability was achieved with the use of a redesigned app. This study offers insight regarding the importance of personalization in enhancing accessibility and also identifies strategies for improving usability in app development.

“…VISYTER is ''a platform for building TR [telerehabilitation] applications that takes into account the diverse settings and requirements of various rehabilitation services.'' 18 The architecture of VISYTER combines three unique concepts to deliver telerehabilitation: a software application that can be installed easily, a set of off-the-shelf hardware to minimize cost, and a secure server system as the backbone of the service. VISYTER was designed to comply with standards for privacy and security of personal information (i.e., the Health Insurance Portability and Accountability Act) and uses industry standard security policies, including an authentication system for all users, which also controls the user's access to specific clinic ''rooms'' or venues, and encryption of all user authentication and the communications between the sites (video and voice) using a symmetric encryption key.…”

Introduction: The Autism Diagnostic Observation Schedule (ADOS) Module 4 is an autism assessment designed for verbally fluent adolescents and adults. Because of a shortage of available clinical expertise, it can be difficult for adults to receive a proper autism spectrum disorder (ASD) diagnostic assessment. A potential option to address this shortage is remote assessment. The objective of this study was to examine the feasibility, usability, and reliability of administering the ADOS Module 4 remotely using the Versatile and Integrated System for Telerehabilitation (VISYTER). Materials and Methods: VISYTER consists of computer stations at the client site and clinician site for video communication and a Web portal for managing and coordinating the assessment process. Twenty-three adults with an ASD diagnosis participated in a within-subject crossover design study in which both a remote ADOS and a face-to-face ADOS were administered. After completing the remote ADOS, participants completed a satisfaction survey. Results: Participant satisfaction with the remote ADOS delivery system was high. The kappa value was greater than 0.61 on 21 of 31 ADOS items. There was substantial agreement on ADOS classification (i.e., diagnosis) between assessments delivered face-to-face versus assessments delivered remotely (interclass coefficient = 0.92). Nonagreement may have been due to outside factors or practice effect despite a washout period. Conclusions: The results of this study demonstrate that an autism assessment designed to be delivered face to face can be administered remotely using an integrated Web-based system with high levels of usability and reliability.

Abstract-Telerehabilitation (TR) is getting ever more popular because it is effective in bringing rehabilitation services to rural populations by means of audiovisual systems and its initial implementation studies presented encouraging results. TR is proven to be helpful, with benefits in terms of reduced travel time, cost, and availability of specialists' support in local communities. However, TR systems that are usable under low-bandwidth network environments are rare. This article introduces the development of a TR system with customized consultation categories for users to choose from, depending on requirements. Each category, with its preset parameter values, is discussed in detail by demonstrating relevant rehabilitation exercises. A novel bandwidth adaptation algorithm is also presented for optimal utilization of the dynamic network conditions, which ensures the system functionality even under narrow-bandwidth environments. Experiment results show that the system is able to perform effectively in each consultation category while the rehabilitation exercises are being performed. The proposed algorithm is also verified for its ability to adapt the content quality and effectively utilize the network under constrained conditions. A survey conducted on the video quality of the system under low-bandwidth conditions shows encouraging results for a large-scale deployment of the application.
