i hope it detects every kind of obstacle and not at the end of the time because at the end time they cannot decide to where to go . so there must be good range by the way what i think is it will work great only in those smartphones who are having best camera . because smart phones with low quality couldnot detect the lines easily so its difficult for them ? .
When blind people open camera at the striped lines and shake mobile back and forth, there will be vibrations if the lines are found creating a direction for routes for those people to walk with freedom and independence. Also there is no any audio interference for notification. They can happily go anywhere and participate in many social activities without any obstruction or wearable gadget.
great idea behind it and i hope many blind people will get benefit from it . great hunt friend keep on hunting 😊
