Abstract:
This paper reports on our user modelling work based on an empirical study of users' behaviour while driving a power wheelchair with a safety assistant. The focus was on persons with visual perceptional deficits, who show deficits to control a power wheelchair safely if no additional assistance system is available. Our major concern is to identify users' behavioural patterns which lead to the intervention of the safety assistant, although the empirical study itself covers many different research aspects. The goal of the current work is twofold: to adapt the safety assistance for users with hemianopsia who lost one half of their visual field and to improve their navigation skill in narrow space via suitable interaction.
