| Abstract: | This research involves the use of an assistive robot which helps elderly people perform physical exercises. The robot presents a physical exercise on the screen which the elderly person has to copy. A camera observes the exercise performed by the elderly person. There are two ways in order to navigate though the exercises namely, in-air gestures and touch. The senior can perform a gesture or press screen buttons. By means of an experimental comparative study, this research aims to discover among others, whether the elderly people have a preference towards an interaction modality. No significant differences were found between the interaction modalities on the technology acceptance measures on effort, ease, anxiety, performance and attitude. The scores on these measures were very high for both interaction modalities, indicating that both modalities were accepted by the elderly people. In the final interview, participants were more positive about the use of gestures than about the use of the touch modality. Most participants had a preference to use in-air gestures for the interaction with the robot because they could express themselves more using gestures as opposed to pressing touch screen buttons. An extra reason to prefer gestures were the physical constraints of many of the participants. In the touch interface they had to walk towards the robot in order to touch the screen. Of the 100 in-air gestures which are interpreted as such by the participants 93 in-air gestures were recognized as such by the gesture recognition system. Elderly participants who were unable to perform the desired gesture were disregarded in determining the quality of the gesture recognition. |
