Effect of scenario media on elder adults' evaluation of human-robot interaction

Abstract

When evaluating user attitudes toward social robots in human-robot interactions (HRIs), one should exploit the rich contextual information in the HRI. Such information is usually represented as HRI scenarios, which can be conveyed using different media. We investigated how different media of scenarios might influence elder adults' evaluation of social robots. Three media (text, video, and live interaction) were used to elicit user acceptance and feedback, where the content of scenarios was kept similar. We found that multiple aspects of user acceptance were influenced by the scenario media. Moreover, more design problems were elicited when users were exposed to media with higher fidelity. The results shed light on the selection of scenario media in HRI evaluation.
