ABSTRACT
Recently, personal digital assistance (PDA) and PC with touch panel are in widespread use in Japan. Although touch panel operation including intuitive manipulation is low-skilled interface for young individuals, the user experience could be influenced by various effects. Therefore, the characteristics of the touch panel operation should be considered. In this study, the touch panel operation of evacuation route map on a PDA were compared with the handling a sheet of printed evacuation route map through experiments. The evacuation route map on the PDA included two semi-transparent buttons for zooming and the map position was moved by mbbing the touch panel with a finger. The regular evacuation route map was printed in black and white onto a sheet of A4 paper. Ten participants of each tried to walk from the specified location to the evacuation center using different types of evacuation route map; however, we focused on the participants' operation of the map. As the results, the participant's haptic interaction with the map was found, and it was revealed that the haptic interaction was useful for understanding
the present location and planning the evacuation route; however, the map on the screen with touch panel prevented the user from haptic interaction, and the user experienced some kind of frustration.
