This is a case for my DIY visual impairment aid. It uses haptic and sound feedback with a distance sensor to let people know how far they are from objects. It fits together with two M3 screws and even has braille for the buttons! For step-by-step instructions on how to make your own and a demonstration video, check out the instructable here: http://www.instructables.com/id/VIA-Visual-Impairment-Aid-Haptic-Sound-Feedbac/

Hi, i work in the blind and vision impaired sector, and have been developing some similar projects. i have looked at your design and do believe that with some modifications to the components used to build it, that you can infact reduse the size of it considerably. however i do not find it entirely necessary. i have done some work with sensory devices that included haptic and auditory feedback, that fit into a light weight case roughly the size of a smart watch. however when we are teaching mobility services to the vision impaired, one of the first things we teach is to have the nuckls flat and fingers and wrists pointing dow, so as not to bump into anything and cause unessecary injury to the hands and fingers. this technique is called bumpers down. if ytour device was to be used in the way that you have prescribed, it would allow for finger injury, or the sensors would be obstructed by the hands and fingers, where the proper safety techniques followed. i do not mean to souynd negative i love the device and i believe that it has many aplications.
i do not think that it should be used to replace traditional mobility aids (cane and guide dog) because they serve more purposes than just identifying obstacles, but i do think this would work very well as an addition to these services. if the device was adjusted to be fitted to a cane or a harness, then i think it could serve several great purposes in orientation mobility, particularly in teaching safe practice in vision impaired children. if you are interested i would love to discuss this further and with your permission, run some design tests and simulations.

very very good project

Nice project! Maybe a little big? Could be nice to be as small as a watch...

Hah alright, well good luck fitting the components in a watch. It's more than just a case if you look at the instructable.
