Modern Blind Stick

We wanted to make use of the belongings a blind person uses on a day to day basis (cane and smartphone). Our product is a simple cane with object detection sensors and a slot to place a smartphone, thereby having two major functionalities. The object detection sensors placed at the bottom would detect the obstacle and alert the person about the same with a beep. This is done to prevent the person to avoid the obstacles like potholes (a major problem in India) during rainy seasons or any other time. This is the first feature of our product. The second feature of our product is to detect what's in front of the person. The camera of the person's smartphone would capture the image in front of him/her with a click of a button on the stick, which would then be analyzed by Google's cloud vision API. The text about the items in front of him would then be read out to the person using text to speech software.
