Vision based interface system for hands free control of an intelligent wheelchair

Abstract: Background: Due to the shift of the age structure in today's populations, the necessities for developing the devices or technologies to support them have been increasing. Traditionally, the wheelchair, including powered and manual ones, is the most popular and important rehabilitation/ assistive device for the disabled and the elderly. However, it is still highly restricted especially for severely disabled. As a solution to this, the Intelligent Wheelchairs (IWs) have received considerable attention as mobilit… Show more

“…Apart from using these singlemodality human bio-signals, computer vision information, speech information and multi-modality signals have been studied and applied as wheelchair control interface. Ju and Shin et al introduced a vision based intelligent wheelchair system developed for people with quadriplegic in [9]. Li and Tan [10] proposed a bimodal wheelchair control approach by integrating vision and speech signals.…”

“…With the recent advancement of machine and computing ability, many HMIs have been developed from computer vision information [11], speech information and multi-modality phenomenon. Ju and Shin et al introduce a vision-based intelligent wheelchair system developed for people with quadriplegic [6]. Li and Tan [7] propose a bimodal wheelchair control approach by integrating vision and speech controls.…”

“…For this reason they are used as assistive robots, attracting the attention of many research groups around the world. Some authors focus their attention on the human-machine interface, proposing alternatives to the control input such as electromyography (EMG) [2,3], bioimpedance [4], BrainComputer Interface (BCI) [5], face detection [6][7][8], or hybrid approaches [9,10]. Others propose different control strategies in order to ensure velocity control, safety and robustness.…”
