This paper explores how seniors perceive Voice User Interfaces (VUIs) and the factors that shape those perceptions. An experiment was administered to 15 seniors (over age of 65), in which the participants searched for information using a traditional keyboard/mouse interface and an experimental voice/touch interface. Throughout the experiment, the participants were observed and interviewed by an investigator. An analysis of the data collected showed that seniors perceive meaningful differences between the two interfaces in terms of learnability, usability, ease of understanding and helpfulness. The data also shows that seniors’ perceptions of the interfaces were most strongly influenced by familiarity, usability, habit, aversion to typing, and efficiency of voice input. These findings have implications for improving the design of VUIs for seniors and accommodating universal accessibility.
