We have considered several different design options for Visioneer such as a bracelet, necklace/pendent, pin, glasses, headband, and assistive case attachment.  Each option has both pros and cons.  Finally we narrowed it down to a design involving both glasses and a headband.  The glasses allows the user to "look around" for traffic and provides a good height for obstacle avoidance.  The headband will hold the power source and help to balance out the overall weight.  This design also allows us to use a bone conduction transducer that provides the best audio signal reception and vibration feedback. 

Based on the component list, schematic, and results of camera experiment, we've come up with the following initial 3D design.

We 3D printed the glasses frame and headband to test for comfort and wearability.
