  1. BACKGROUND: Today, various emerging assistive applications (apps) running on smartphones have been introduced such as Seeing AI, TapTapSee, and BeMyEyes apps. The assistive apps are designed to assist people with visual impairment in navigating unfamiliar environments, reading text, identifying objects and persons. Yet, little is known about how those with visual impairment perceive the assistive apps. OBJECTIVE: This study aims to advance knowledge of user experience with those assistive apps. METHODS: To address the knowledge gap, this study conducted phone interviews with a convenience sample of 30 individuals with visual impairment. RESULTS: The results indicated that those with visual impairment showed a range of preferences, needs, and concerns about user interfaces and interactions with the assistive apps. DISCUSSIONS: Given their needs and concerns, this study offered a set of facilitators to promote user adoption of the assistive apps, which should be valuable guidance to user interface/interaction designers in the field.

  2. People can visualize their spontaneous and voluntary emotions via facial expressions, which play a critical role in social interactions. However, less is known about mechanisms of spontaneous emotion expressions, especially in adults with visual impairment and blindness. Nineteen adults with visual impairment and blindness participated in interviews where the spontaneous facial expressions were observed and analyzed via the Facial Action Coding System (FACS). We found a set of Action Units, primarily engaged in expressing the spontaneous emotions, which were likely to be affected by participants’ different characteristics. The results of this study could serve as evidence to suggest that adults with visual impairment and blindness show individual differences in spontaneous facial expressions of emotions.
  3. Today, a great number of people with visual impairment take advantage of mainstream technology via assistive technology. User involvement in the systems development life cycle contributes to addressing user needs accurately. This article presents practical strategies to facilitate participatory design approaches involving users with visual impairment. Both researchers and professional designers will benefit these practical strategies by using them as action checklists for preparing, conducting, and concluding a participatory design session ethically and responsibly.
  4. BACKGROUND: Although a number of research studies on sensor technology for smart home environments have been conducted, there is still lack of consideration of human factors in implementing sensor technology in the home of older adults with visual disabilities. OBJECTIVE: This paper aims to advance knowledge of how sensor technology (e.g., Microsoft Kinect) should be implemented in the home of those with visual disabilities. METHODS: A convenience sample of 20 older adults with visual disabilities allowed us to observe their home environments and interview about the activities of daily living, which were analyzed via the inductive content analysis. RESULTS: Sensor technology should be integrated in the living environments of those with visual disabilities by considering various contexts, including people, tasks, tools, and environments (i.e., level-1 categories), which were further broken down into 22 level-2 categories and 28 level-3 categories. Each sub-category included adequate guidelines, which were also sorted by sensor location, sensor type, and data analysis. CONCLUSIONS: The guidelines will be helpful for researchers and professionals in implementing sensor technology in the home of older adults with visual disabilities.
