GLASSES TO ASSIST A BLIND OR VISUALLY IMPAIRED PERSON
A multifunction device capable of communicating different information in the most varied competitions to children, adults and the elderly who are blind and partially sighted. The technology detects obstacles remotely via ultrasonic sensors and communicates to the user via haptic actuators placed on the rods of a pair of glasses, as well as the hands that can thus be used to use a white cane or guide dog.
These glasses can distinguish between distant obstacles (up to 8 metres) and proximity obstacles (< 2 metres). For distant obstacles, the system can also indicate whether the obstacle is on the right or left side, and for proximity obstacles the detection is frontal and is communicated to the user via vibration of the nasal support of the glasses. The daily needs of a blind person include being able 1) to detect an obstacle (obstacle detection mode) and 2) to be guided to a specific destination (navigation mode). The technology can be used by external devices as an output interface to communicate useful information to guide e.g. a patient in a hospital or other public institution, or in work situations. It is possible to equip the device with audio feedback by integrating bone-conduction earphones to provide specific and non-invasive information during the most critical phases of mobility.
- Stand-alone devices to attach to any glasses frame;
- Mounting kit for replacing only one part of the device in the case of malfunctioning;
- Device for better guidance in indoor and outdoor environments;
- Device adaptable to any need, even with audio integration.
- Feedback on the presence of obstacles according to direction (right and left);
- Feedback on presence of obstacles based on proximity (different intensity and frequency);
- Information on lighted/unlighted environment;
- Integration with other devices, such as smartphones or smartwatches, using dedicated app and, for example, interactive Google Maps.
