Haptic Vest and Haptic Toolkit


[Main Project Page] | [Haptic Vest 1] | [Haptic Vest 2]



Haptic Vest is a vest that enables vision-impaired users to experience their surroundings by vibratory actuations on the belly. A person can feel a depth image of what is in front of them. An Asus Xtion depth camera mounted on the chest captures the area in front of a person. This is then translated into PWM values to control an array of vibration motors. Each vibration motor represents a pixel of the downscaled image, and the intensity of the vibration displays how far away on object at this position is. This project was formerly called OpenVNAVI and was developed by David Sanchez. It was later renamed to VibroVision and then to HaptiVest.

Besides from the setup for controlling large numbers of vibration motors we also develop a more general toolkit for using multiple sorts of sensors and actuators called YAWN.

  • Jun 13, 2017: Our Haptic Vest 2.0, a wearable vest that renders depth images from a front-facing camera onto the wearer's torso using an array of vibration motors, enabling people with vision impairments to avoid obstacles while walking, was featured in a dedicated TV report in WDR Lokalzeit Aachen today. The report (in German) starts at 14'50" into the program (local cached copy).
