A wearable computer vision device developed by Harvard Medical School scientists may help reduce collisions and other accidents for the blind and visually impaired.
The device includes a data recording unit enclosed in a sling backpack with a camera on the strap, and two Bluetooth-connected wristbands.
The researchers said a processing unit records images from the camera and analyzes collision risk based on the motion of incoming and surrounding objects within the field of view.
The left-hand or right-hand wristband will vibrate an alert depending on which side a potential collision is coming from, while both wristbands vibrate when a potential head-on collision is detected.
Data from the study showed the solution cut the risk for collisions and falls by nearly 40% compared with other mobility aids, when used in combination with a long cane or guide dog.
