Our Design

Below is concept art for "The Speed Stick."

What the art shows is a blind person being alerted that there is an object in front of them before the end of their stick makes contact with the object.  This is being performed with a microcontroller interfacing with an ultrasonic range finder and a cell phone vibrator.

There is, however, one additional functionality to "The Speed Stick."  Our device can also determine if there is an object moving toward it at a speed above a certain threshold.  It then communicates this information to the user with a unique vibration pattern so that they are aware that there is an object moving toward them.
