[tpsully]’s Radar Glasses are designed as some way of sensing the sector with out some great benefits of customary imaginative and prescient. They include a distance sensor at the entrance and a vibration motor fastened to the bridge for haptic comments. The little motor vibrates in share to the sensor’s readings, offering hands-free and intuitive comments to the wearer. Impressed partially by means of his personal stories with brief blindness, [tpsully] prototyped the glasses from an accessibility standpoint.
The sensor is a VL53L1X time-of-flight sensor, a LiDAR sensor that measures distances with the assistance of pulsed laser gentle. The glasses don’t in truth use RADAR (which is radio-based), however the operation is in a way moderately identical.
The VL53L1X has a most vary of as much as 4 meters (more or less 13 ft) in a somewhat slender box of view. A person due to this fact scans their setting by means of sweeping their head throughout a desired house, feeling the vibration depth trade in reaction, and letting them building up a form of psychological intensity map of the speedy house. This bodily scanning resembles RADAR antenna sweeps, and serves necessarily the similar objective.
There are every other tasks with identical concepts, such because the wrist-mounted virtual white cane and the hip-mounted Stroll-Bot which integrates more than one angles of sensing, however one thing in regards to the glasses shape issue turns out attractively intuitive.
Because of [Daniel] for the top, and needless to say in case you have one thing you’d love to tell us about, the information line is the place you’ll be able to do this.
