Summary
A prototype electronic device for aiding the visually impaired in independent travel is reported in the paper. The device contains a stereovision module consisting of 2 MPix resolution digital cameras, a sound card and a processor that controls image acquisition and data recording from linear acceleration and angular velocity sensors. The modules communicate with a computer via single USB 2.0 interface (USB 2.0 hub is used). The device is powered directly from the USB port. Electrical current drawn by the module does not exceed 450 mA. This prototype system is a key element in electronic travel aid for the visually impaired.
