The Visually Impaired usually encounters various difficulties when going out on their own. To improve their mobility, there are some kinds of tools and technologies available in the market. For instance, blind canes are used to extend the user's range of tactile sensation; and guide dogs can lead the user to his/her destination and assist them to avoid obstacles and irregularities on the road. Also, GPS devices can assist the user by providing orientation and navigation information. And LSCM has developed a cost-effective robot vision and sensing technology for mobility assistance. The technology has been developed to simulate important functionalities provided by guide dogs, including obstacle avoidance and guidance. It is equipped with navigation and locationing functions that can provide walking guidance to the user for free walking and going to the target destination.
