Paper Abstract

Applying the principle of mechatronics, this paper presents design considerations for a new type of sensor-embedded 'smart' long cane which can serve as an orientation and travel aid for the blind. The smart long cane uses a set of miniaturized ultrasonic sensors to detect obstacles along the travel path, and provide human voice feedback on the obstacle's height and distance to guide the cane user away for head collisions and subsequent injuries. Topics discussed include sensor array design, placement, and integration, structure of the embedded software, and ergonomic issues for the new cane design.
