We have seen Kinect used in a variety of clever ways over the last few months, but some students at the [University of Konstanz] have taken Kinect hacking to a whole new level of usefulness. Rather than use it to control lightning or to kick around some boxes using Garry’s Mod, they are using it to develop Navigational Aids for the Visually Impaired, or NAVI for short.
A helmet-mounted Kinect sensor is placed on the subject’s head and connected to a laptop, which is stored in the user’s backpack. The Kinect is interfaced using custom software that utilizes depth information to generate a virtual map of the environment. The computer sends information to an Arduino board, which then relays those signals to one of three waist-belt mounted LilyPad Arduinos. The LilyPads control three motors, which vibrate in order to alert the user to obstacles. The group even added voice notifications via specialized markers, allowing them to prompt the user to the presence of doors and other specific items of note.
It really is a great use of the Kinect sensor, we can’t wait to see more projects like this in the future.
Stick around to see a quick video of NAVI in use.
