A Smart 'Virtual Eye' Mobile Prototype System For The Visually Impaired

摘要

This article presents a wearable mobile smart prototype system that can be used as the "virtual eyes" to assist visually impaired to navigate their surroundings. The smart system consists of two units: (1) an imbedded wearable smart sensor unit that uses ultrasound sensor to detect objects in front and sends the data to the other unit through Bluetooth; and (2) a smartphone that processes the detected object data from the other unit, utilizes the smartphone GPS unit to obtain orientation and location information, and feeds the visually impaired the critical surrounding information in real-time through Text-to-Speak (TTS) and/or vibrate warning signals.
