Healthcare is an important part of life in most societies that attract a significant amount of public investment. Primary healthcare is a fundamental branch of the healthcare system where patients and doctors initially meet. Family Medicine Information Systems are developed in an effort to ease the daily work of family doctors with the help of information technology. Such systems are generally used for handling critical tasks such as managing health records of patients, monitoring pregnancy and keeping track of children&rsquo / s vaccination. Like any medical information technology, the usability of such systems is a vital concern for enabling efficient and effective primary healthcare operations. Family Medicine is a recently established practice in Turkey and there are a number of systems in service to aid the daily work of family doctors. However, none of these systems have been subjected to a systematic usability analysis. In this study, a usability analysis of a popular Family Medicine Information System used in Turkey is conducted. By combining several usability evaluation techniques, the study identified several important usability issues and provided recommendations for further improving the system. The main usability issue observed in the system was the overall complexity of the information presented at the main interface that often confused and misled the users. In order to address this problem, it is suggested that features related to the most frequent family medicine operations should be placed on the main screen, whereas remaining features should be organized under auxiliary pages with clear navigation aids.

<p>An application was developed to explore user interactions with the holographic sign language interpreters within HoloLens MR classrooms for Deaf and Hard of Hearing (DHH) students. The proposed system aims to enhance DHH students’ learning efficacy. Despite the ongoing advancement of assistive technology and the trend to adopt Mixed Reality applications into education, not much existing research provides user study or design guidelines for HoloLens development targeting the DHH community. The developed HoloLens application projects a holographic American Sign Language (ASL) avatar that signs the lecture while a speaking instructor is teaching. The usability test focused on avatar manipulation (move, rotate, and resize) and avatar framing (full-body and half-body displays) within the MR classroom. A mixed-method approach was used to analyze quantitative and qualitative data through test recordings, surveys, and interviews. The result shows user preferences toward viewing holographic signing avatars in the MR space and user acceptability toward such applications</p>

Age-related physical and cognitive changes hinder the ability of older adults to operate smartphones. While many user interface (UI) heuristics exist today, there is a need for an updated set designed specifically to assess the usability of mobile devices for an older audience. Smartphone evaluation heuristics for older adults based on age-related changes in vision, hearing, attention, memory and motor control were developed in this thesis by analyzing literature on age-related physical and cognitive changes impacting smartphone usability. Support for heuristics was found by gathering information on how older adults use cell phones through interviews and an online survey. It was demonstrated that strength of support for some heuristics increases with age. The evaluated heuristics provide usability practitioners and designers with a framework for evaluating the usability of smartphones for older adults.
