Visually handicapped people are facing difficulties to perform everyday communications. Sometimes, bad eye sight occurs to many people for reduced self confidence due to not being able to perform independently. This is an innovative concept device that will help visually handicapped people when they are in a mobile situation.

One good example of such situations is when a visual handicapped person wants to illuminate for instance images or illustrations which can... (more...)
