Wheelchair Users' Psychological Barrier Estimation Based On Inertial And Vital Data

Wheelchair users face many "barriers" that interrupt their movement outside. In order to support wheelchair users' comfortable movement, many studies use crowd-sourcing to understand the "barriers". However, barriers can be classified into physical barriers and psychological barriers, and many studies focused on only physical barriers. Psychological barriers disrupt the wheelchair users by increasing the level of stress. For example, too much traffic or inadequate visibility make the users anxious or stressed. It is important to understand psychological barriers to support wheelchair users' safe/comfort movement. We focus on the psychological barriers and propose a method for estimating the impact of such barriers. As the metric, we use "ride comfort". This paper gathers and processes inertial and vital data to propose a ride comfort estimation method.
