The mobile device operates when the user presses a central button scanning the surrounding area for the closest infrared emitter signal. Emitters may be located in facilities such as bathrooms, offices and retail stores. Once the signal is received by the device, the corresponding audible message is activated in order to communicate the details of the location to the user.
The ergonomic curved design of the hand held device complements the anatomical nature of the hand, which results in maximum comfort. The textured surface provides tactile feedback and minimizes slippage in the hand. In short, SUAM achieves audio signaling serving as a user-friendly, unobtrusive guide for the blind or visually impaired.
