How to use: Open Argos, hand your phone in front of the traffic light that you want to detect its color. Double tap any place of the screen, a voice message of whether the traffic light is red or white will be delivered. If no traffic light is detected, voice message "no traffic detected" will be delivered. In addition to voice message, the phone will also vibrate three times if it's white light, and vibrate one time if it's red light.
Although it's a primitive APP, we want to at least help people suffering from visual impairment to have a more convenient life.
