Intelligent assistive sensors and smart systems for the control and analysis of driver reaction times

Intelligent assistive sensors and smart systems for powered wheelchairs are presented and used to analyze ways to improve mobility and enhance the quality of life of powered wheelchair users. Time-delays are introduced to investigate their effects. Systems interpret joystick signals and sensor signals and then mix them together. Ultrasonics are used to identify hazards and the intelligent systems suggest safer directions and speeds. Wheelchair drivers were observed while they completed tasks. Time-delays were introduced, wheelchair users undertook tests with and without intelligent systems, as delays were extended then more failures were recorded. Systems were practically tested. Results from drivers completing a series of timed routes are presented Results are compared and contrasted with recent systems and systems presented in this paper outperformed recent systems. Also the level of support provided by the systems should be adjusted depending on conditions and environments. Clinical trials will be conducted at Chailey Heritage Foundation as part of broader research conducted by the authors.
