This is an attempt to help blind people get a visual representation of their surroundings to get transmitted to them. The setup is made up of a camera that records the surroundings of the device’s user. The recorded video signal is converted into black and white. The signal is converted to black and white because black and white pictures are basically an array of white light signals with different brightness levels. It is the relative brightness of different points of the display panel that gives the illusion of an image or video signal. This video signal is then transmitted to the output of the panel, which is a surface that is attached to a part of the skin that is somewhat flat and spacious. I would recommend the stomach or chest and back regions as ideal places for our display panels. Smaller display panels can be placed on the palm of the user’s hand. The output panel can be constructed as an array of blunt needles that press on the user’s skin at different points. The force exerted by a needle is directly proportional to the brightness of the spots that it corresponds to on the black and white image. Instead of the needles pushing the user’s skin at different spots, they can be designed so that the tips of the output needles vibrate. Here more vibration is perceived at points that correspond to the brighter brighter parts of the black and white display. With a little practice, a blind person can get accustomed to interpreting the touch signals as visual signals. The display can be adapted have zooming properties and 360 vision.
