The need for a special housing for the blind should be judged against the objective of blind welfare and the design should be as a determent to him to regain his confidence in leading a normal life. Any unusual design features should be kept to minimum. Because blind people function efficiently by relying on memory and the following design guidelines are important. Depending on the cause of diminished vision, altering the interior can help to improve eyesight and prevent falls. Options are numerous, but should include the following as a minimum:
Light levels may need to be raised (or lowered depending on the disease).
Lighting should be located to avoid glare and shadows.
Dramatic changes in light levels should be avoided.
Signage should include raised letters (Braille) and sufficient type size for ease of reading.
Changes in elevations, such as steps, should be avoided. If required, they should be clearly demarcated.
Edges of tables and other surfaces, such as counters, should be clearly delineated by a change in surface texture and/or color.
Auditory and tactile design qualities should be enhanced, as these senses are more acute in people with visual challenges.
Simply put these are the important features;
Design around hearing and touch
Floor to be kept of sufficient hardness & non-slippery
