A Low Vision scenario is one where the person still has some sight available which he/she can use. However, what defines the situation as Low Vision-specific, is the fact that the person requires one or more of several image enhancements in order to see an image clearly. When referring to a text document for example, these enhancements may include magnification, contrast or colour manipulation or any combination of these. In some cases, the addition of speech will make the information even further accessible, especially where the Low Vision person finds that his/her available sight changes through the course of a day. Information can be made accessible through magnification, contrast manipulation, colour manipulation and Speech.
There are cases where no amount of magnification, contrast or colour manipulation can enhance an image in order to make it “visible” to the user, even where such a user still has some sight left. Naturally, in a case where the user has no light perception at all, sight is unavailable and the solution requires other inputs. In both of the above descriptions, we are faced with a Blindness scenario. A Blindness solution relies on two primary features namely Audio and Tactile. We define Audio as the use of speech, real or synthetic, to read information to the user. Tactile on the other hand is the use of either Braille or Tactile graphics to represent images or information to the user.
