Affective interpretations of assisted driving interventions on a smart-wheelchair : an exploratory study Estrada Gaspar, Ariadna M.


Allocating authority appropriately between humans and machines in shared control applications is crucial for the performance of the system. Particularly in the context of collaborative wheelchairs, the arbitration should be sensitive to user needs and preferences in order to avoid confusion and frustration. Current approaches to shared control for wheelchair navigation have been designed to handle objective and functional information such as goals and system states with limited analyses to subjective information such as the user’s feelings when an assisted driving intervention is introduced. This thesis explores user affective responses on smart-wheelchairs as a potential communication channel through which users could interact more effectively with their smart mobility device. We present an implementation of shared control paradigms from the smart-wheelchair literature and results from a study where participants reported their affective interpretation of the emerging behaviours.
