Wheelchairs play an important role for people living with locomotor impairments. However, power wheelchair users frequently report both minor and major accidents. The goal of this paper is to advocate for the use of robotic technology, in particular sensor-based detection and automatic classification of activities, to track and characterize activities onboard smart wheelchairs. Experiments were conducted...
This paper presents a method to automatically recognize events and driving activities during the use of a powered wheelchair (PW). The method uses a support vector machine classifier, trained from sensor-based data from a datalogging platform installed on the PW. Data from a 3D accelerometer positioned on the back of the PW were collected in a laboratory space during PW driving tasks. 16-segmented...
