The Wearable Prototype

My research focuses on assistive technology to aide mobility for the blind and low vision community, and hence a wearable technology is proposed. The wearable prototype consists of a small embedded computer, a lightweight stereo camera and an inertial measurement unit. The design is minimalistic and therefore unobtrusive, fulfilling a key practical requirement identified by the BLVs.

The following images depict my prototype of the wearable technology, in which it is built to augment the perception of a BLV along their navigation pathway.

Inserted pictures - 
A: a compact stereo camera and IMU (inertial measurement unit) sensors, 
B: an embedded processor,
C: a power source.

The following video shows some data sets collected using the stereo camera of the prototype. Several different surface discontinuities can be seen from the image (video) pair.
