Design and implementation of a Vision Stick with Outdoor/Indoor Guiding Systems and Smart Detection and Emergency Features

A smart vision stick, used to powerfully help visually impaired people with new attractive features, is designed and tested. The stick comprises mainly of three parts namely, an indoor/outdoor guiding system, an emergency system and a smart detection system. The stick is designed such that the user can interact with it via a set of voice recognition commands that allow him to specify the destination name and then receiving a response from the stick immediately with full instructions that describes the directions and distances. For the outdoor guiding scenario a real time google map is used via a developed mobile application. The indoor guiding system is developed based upon a set of predefined locations with an accelerometer that help in measuring distances. Finally, a commercially available Global Position System (GPS) unit is used for the smart emergency system that ensures users' safety in any unusual condition.
