Self-calibration of an Assistive Device to Adapt to Different Users and Environments.

Abstract

In this paper, we describe the implementation of a strategy to increase the robustness of an assistive device to changes of the user and/or the environment. The device is a smart handle that can be mounted on an electric wheelchair or trolley. This handlebar replaces the attendant joystick to achieve a more intuitive driving. In spite of having been successfully tested, there are concerns about its behavior when the driver or the surroundings change. Sensors have been added to the system to detect these changes and re-calibrate the system accordingly.
