Smart Wheelchair.


About 36 million people worldwide are blind. For many of these people, navigating new spaces can be a cumbersome or frustrating experience as they listen and feel their way around their environment.

Our project seeks to utilize the spatial mapping power of the Microsoft HoloLens augmented reality device in order to help users navigate in unfamiliar environments.  This could improve independence for blind people by allowing them to find and read objects such as bus stops without sighted assistance.

The proposed system includes a depth camera for acquiring the depth information of the surroundings, an ultrasonic rangefinder consisting of an ultrasonic sensor and a MCU (Microprogrammed Control Unit) for measuring the obstacle distance, an embedded CPU (Central Processing Unit) board acting as main processing module, which does such operations as depth image processing, data fusion, AR rendering, guiding sound synthesis, etc., a pair of AR glasses to display the visual enhancement information and an earphone to play the guiding sound.
