The Touch Sight camera is designed by Chueh Lee from Samsung China to allow visually impaired users to "touch" a photo. Additionally, it records a few seconds of sound with each picture:
The user can then use the sound as reference when reviewing and managing the photos. Touch Sight does not have an LCD but instead has a lightweight, flexible Braille display sheet which displays a 3D image by embossing the surface, allowing the user to touch their photo. The sound file and picture document combine to become a touchable photo that is saved in the device and can be uploaded to share with others–and downloaded to other Touch Sight cameras.
It isn't clear whether the Braille 'display' can be used as a kind of touch viewfinder when composing the shot. If so it could even become a kind of visual aid for everyday use! [via Reaction!]
