We are only as blind as we want to be. In this paper, The Lé Vision is one assistive technology product that is focused on helping people with vision loss to be able to read. The device recognizes texts, snaps a picture, and relays the message to the user via an audio outlet device. The device is small, portable, and discreet allowing users to blend in with the crowd. To reduce the creation cost, we used a single-board computer, such as Raspberry Pi. It also provides obstacle detection enhancing the travelling experience of the visually impaired. We attach ultrasonic sensors for measuring the distance, interfaced to the Arduino. The presence of an obstacle is intimated via haptic feedback.
