The iGlasses Ultrasonic Mobility Aid is a head-mounted device which uses. Tactile Navigation Tools is developing two different versions of the vest. The Ambutech Aluminum Folding Mobility Canes are folding travel canes designed. However, he said he suspects that "as someone gets used to the vibrations and what they mean, it's going to become hardwired, until the person doesn't have to consciously think about it." The device is designed to be intuitive, but the brain still needs to be trained to interpret the vibrations, Rizzo said. In the same example, if the dog were running toward the person in the vest, the garment would buzz faster and faster. The device will represent a third dimension (depth) using the frequency of vibration. For example, when the vest senses a dog in the wearer's lower left field of view, vibrators on the lower left part of the vest (as viewed by the wearer) will activate. As obstacles get nearer, the frequency of the vibration. iGlasses uses ultrasonic sensors to alert the wearer to objects in their path with a gentle vibration to indicate objects are detected. When the sensors detect an object, their signals will be converted into vibrations in a corresponding part of the vest.

The iGlasses Ultrasonic Mobility Aid is a head-mounted device which uses ultrasonic sensors to detect objects and communicate via gentle vibrations. People) and AmbuTech Ultrasonic Mobility Aid is a head- mounted device which uses ultrasonic sensors. The vest will have different types of sensors, including lidar, a laser-based system used in driverless cars ultrasound, a type of high-pitched sound used by bats and other animals for echolocation and infrared, a type of electromagnetic radiation used by some animals to detect body heat from their prey.
