Our eyes are a great gift that we all take for granted. You can’t get around easily if you can’t see properly. But technology is going to make life much easier for visually-impaired individuals. Take this acoustic navigation system. It is a wearable device that provides hands-free guidance and obstacle-detection.
The system has two parts: a head-mounted navigation device and a tactile sensor that can be worn on the user’s finger. Both systems rely on ultrasonic rangefinder modules to detect obstacles and provide feedback. Technologies like this can make a big difference in people’s lives, don’t you think?
