摘要
This study aims to conduct objective user evaluation of mental commitment robots for elderly care using psychophysiological methods, including heart rate, skin temperature, skin conductance, and eye gaze data. In stage 1, four males and five females aged from 57 to 67 years old were recruited to interact with eight robot prototypes. The purpose was to validate whether the measures are capable of differentiating the semi-elderly and elderly users feelings about the robots, as well as capturing a rough preference of the robots anthropomorphism, size, weight, voice pitch, and covering material. In stage 2, two teleoperated robots and two autonomous robots were adopted in real human-robot interaction (HRI) with six males and 10 females aged from 52 to 80 years old. The results reflect the semi-elderly and elderly users preference in real HRIs, which may facilitate the developers to respond to the market more closely and effectively.
