Older Adults' Perception and Use of Voice User Interfaces: A Preliminary Review of the Computing Literature

Voice User Interfaces (VUIs) are quickly becoming ubiquitous. The natural language interface of VUIs may be more usable for some groups of users, such as those who may face challenges using physical input methods including older adults and people living with a disability. This study explores research on the use of VUIs by one such group, older adults. We conducted a systematic literature review of research published in the Association of Computing Machinery Digital Library that addresses perception and use of VUIs by older adults. We identified an emerging body of research examining older adults' use and perceptions of VUIs. This research revealed several potential benefits of voice interaction for older adults while also highlighting how the novelty of the technology may be a barrier to adoption. We conclude with a call for further HCI research in this area.
