This paper presents the usability assessment of the design of an Internet of Medical Things (IoMT) system for older adults; the evaluation, using heuristics, was held early on the design process to assess potential problems with the system and was found to be an efficient method to find issues with the application design and led to significant usability improvements on the IoMT platform.

Mobility is a key component for older adults to maintain wellness and health while aging-in-place independently. However, older adults with mobility impairments may experience challenges in remaining socially connected. Telepresence systems hold much potential to help older adults with mobility impairments. However, telepresence systems are not specifically designed with this population’s capabilities and limitations in mind – creating many potential usability barriers. We conducted a heuristic evaluation of three telepresence systems. The results of the evaluation indicated a range of design issues. Issues related to the base height, un-adjustable screen height, camera resolution, microphone/speaker quality, and sensor sensitivity were categorized as hardware problems. Usability issues caused by poor network connectivity, lack of privacy settings, lack of notifications of the system status, and limited control of the system were identified as software problems. It is critical that designers consider and address these findings to ensure that telepresence systems are usable by individuals with a wide range of abilities.

Smart Home Technology

Smart home technology can help older adults maintain independent lifestyles. Recent technological advancements have made smart home technology less expensive and more attainable for the average consumer. Older adults with limited technology experience can benefit from smart home systems with more natural interactions. One such example is the smart speaker, a device with a voice user interface. However, smart speakers are not explicitly designed for older adult use, thereby raising usability concerns. We conducted a heuristic evaluation of a smart speaker system. The results revealed several violations of both Nielsen’s and additional heuristics. Voiced agent interactions were rigid, unnatural, and uninformative. The companion mobile application was difficult to navigate and used low-contrast imagery. Future considerations of age-related differences will make smart speakers and other voice-user interfaces more usable for the aging population.

Usage Data

Objective: To assess the usability and acceptance of activity tracking technologies by older adults. Method: First in our multimethod approach, we conducted heuristic evaluations of two activity trackers that revealed potential usability barriers to acceptance. Next, questionnaires and interviews were administered to 16 older adults ( Mage = 70, SDage = 3.09, rangeage = 65-75) before and after a 28-day field study to understand facilitators and additional barriers to acceptance. These measurements were supplemented with diary and usage data and assessed whether and why users overcame usability issues. Results: The heuristic evaluation revealed usability barriers in System Status Visibility, Error Prevention, and Consistency and Standards. The field study revealed additional barriers (e.g., accuracy, format) and acceptance-facilitators (e.g., goal tracking, usefulness, encouragement). Discussion: The acceptance of wellness management technologies, such as activity trackers, may be increased by addressing acceptance-barriers during deployment (e.g., providing tutorials on features that were challenging, communicating usefulness).

Medication Reminder

For older adults, managing medications can be a burden and could lead to medication non-adherence. To decrease risks associated with medication non-adherence, healthcare providers may recommend medication reminder apps as an assistive tool. However, these apps are often not designed with consideration of older adults’ needs, capabilities, and limitations. To identify whether available apps are suitable for older adults, we conducted an in-depth cognitive walkthrough and a heuristic evaluation of the most commonly downloaded medication reminder app. Findings revealed three main issues: 1) difficulty in navigation, 2) poor visibility, and 3) a lack of transparency. We also selected the top five downloaded medication reminder apps and categorized user reviews to assess app functionality and usability problems. The results of our analysis provide guidance for app design for older adult users to provide effective tools for managing medications and supporting patient/user health.

The aim of this paper is to present a non-exhaustive set of 36 design patterns for interactive social applications used by older adults. This proposal represents a reliable starting point for designers/developers to easily incorporate usability in interfaces for said technology promoting technology acceptance, use and adoption among older adults. The proposed patterns were based on previous efforts commonly presented as a design criteria and guidelines to describe usability issues in this kind of interfaces, reinforcing those alternatives by specifying related usability issues and providing solutions in a pattern-fashion useful for designers/developers. Pertinence of the patterns was analyzed through a usability study implementing «heuristic evaluation» technique (frequently used in Human-Computer Interaction to obtain users’ perception on a particular design). The study was conducted from two perspectives: the vantage point from experts, and the perception of a social group of older adults. The analysis revealed the proposed patterns are conducive to create well-designed interfaces able to provide a better user experience, encouraging a positive impact in the quality of life in older adults. El objetivo de este artículo fue proponer una colección no exhaustiva de 36 patrones para el diseño de interacciones en aplicaciones sociales para adultos mayores. La propuesta representa un punto de partida confiable para facilitar, a diseñadores/desarrolladores, la integración de usabilidad en las interfaces de estas tecnologías con el fin de fomentar su aceptación, uso y adopción entre los adultos mayores. Esta propuesta se basa en esfuerzos previos comúnmente expresados como criterios y guías de diseño para definir los posibles problemas de usabilidad en este tipo de interfaces, y se concentra en reforzar estos enfoques mediante la integración de una mayor descripción de tales anomalías y alternativas de solución bajo una estructura de patrones útil para los diseñadores/desarrolladores. Se realizó un estudio de usabilidad con la técnica «evaluación heurística» (comúnmente utilizada en interacción hombre-máquina para obtener la percepción de los usuarios sobre un diseño particular). El trabajo se llevó a cabo desde dos perspectivas: el punto de vista de expertos técnicos y la percepción de un grupo social de adultos mayores. Los resultados reflejaron que los patrones propuestos propician la creación de interfaces bien diseñadas capaces de ofrecer una mejor experiencia de uso y promueven un impacto positivo en la calidad de vida de los adultos mayores.

Age Related Changes

Older adults may benefit from using activity monitoring technologies to support health and wellness management. However, adoption of such technologies is contingent upon ease of use considerations. Age-related changes in cognitive and physical capabilities impact usability. Heuristic evaluation of two such technologies revealed important ease of use design issues that may be particularly problematic for this user group. Case studies of four older adults’ usage experiences over a two-week period revealed additional usability challenges. Human factors involvement in product development should address these issues to enable older adults to use these potentially beneficial technologies.

Cognitive Control

Abstract Cognitive control constrains retrieval processing and so restricts what comes to mind as input to the attribution system. We review evidence that older adults, patients with Alzheimer's disease, and people with traumatic brain injury exert less cognitive control during retrieval, and so are susceptible to memory misattributions in the form of dramatic levels of false remembering.
