visionear's second feature can tell the blind what colour is in front of them. There are also several mobile applications for this ,but the colours provided are too many. they give around 360 shades of colour. "The blind only need to know the basic colour. For example ,blue-not navy blue,sea blue,or any other shade of blue,"said Nick.
The third feature was quite beyond our expectations. The blind need the gadget to help them check whether the lights in the room are turned on or off , otherwise they would end up paying higher electricity blils. The Visionear camera focuses on the most luminous spot in the room - the light . If there is a spot,it means the light is turned on.
