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.

We conducted a systematic literature review of the human factors literature at the intersection of voice user interfaces (VUI) and older adults among Human Factors publications. Our review was limited to research published in the past 50 years (1970 – 2020) in either the journal Human Factors or the Proceedings of the Human Factors and Ergonomics Society. While we included a broad array of search terms related to VUIs, we found very few articles about VUIs that were specifically focused on designing for older adults or used older adults as participants in studies. Of the 26 human factors publications we did find that were related to this topic, most found older adults take more time to operate VUIs and/or made more errors than younger adults, whereas a minority of publications found no age-related differences. We concluded that age-related differences in the use of VUIs are likely task specific.

This paper studies the usability methodologies for spoken dialogue web interfaces along with the appropriate designer-needs analysis. The work unfolds a theoretical perspective to the methods that are extensively used and provides a framework description for creating and testing usable content and applications for conversational interfaces. The main concerns include the design issues for usability testing and evaluation during the development lifecycle, the basic customer experience metrics and the problems that arise after the deployment of real-life systems. Through the discussion of the evaluation and testing methods, this paper argues on the importance and the potential of wizard-based functional assessment and usability testing for deployed systems, presenting an appropriate environment as part of an integrated development framework.

Telepresence has the potential to assist older adults to stay socially connected and to access telehealth. Telepresence was initially created for office use, thus the usability of telepresence for older adults remains unknown and there is a lack of design recommendations, particularly those with an emphasis on users’ age-related needs and limitations. To bridge the gap, this study assessed two telepresence user interfaces (UIs). One UI was designed to mimic common features founds in commercially available telepresence systems. Another UI was designed based on design guidelines for older adults. Each UI was integrated to a virtual driving environment created via Unity. To assess the usability of both UIs, thirty older adults participated in usability testing. Questionnaires and semi-structured interview were administered following each UI test sessions. Results of this study provide insight on what usability features are critical for the aging population to use telepresence, such as high color contrast, automated controls, and consistent icons.

This paper describes and analyzes the state of research in Voice User Interfaces (VUIs) in Latin America based on the review of scientific documents published in SCOPUS from 1999 to June 2020, through a bibliometric analysis. We analyzed 419 academic papers. Although a gradual increase is observed over the years, the number of published documents has increased considerably since 2014. Brazil (44%) and Mexico (28%) are the countries with more documents published. Co-authorship occurs between Latin American countries (Brazil, Argentina, Mexico, Ecuador, and Costa Rica). However, the mayor collaboration from Latin American countries occurs with the United States, France, Germany, Spain, Portugal, the United Kingdom, and Japan. The main researched topics are studies of automatic speech recognition, artificial intelligence, speech processing, and human-computer interaction, which have grown over the past few years. Natural language processing, conversational agents, user experience, and chatbots are keywords related to more recent studies. Our analysis reveals that the primary active research developed in the short-term future are personal assistants and assistive technology using voice user interfaces.
