Yesterday we saw the awesome ‘Minority Report’ Kinect hack, today we have another one, this time in the form of an air guitar, which was created by Chris O’Shea.
Chris created this fun hack using a Microsoft Kinect, with c++m openFrameworks and openCV and some drivers to get the Kinect to detect himself playing an air guitar.
In 2007 I attempted to make a simple Air Guitar prototype using a stereo camera (watch video). Unfortunately it didn’t work very well.
Now that the much anticipated Xbox Kinect camera was out and opening up by the way, I wanted to port this demo to explore what the potential of interactive music games could be in the future & also just to experiment with the Kinect. So here is the outcome so far…
Technical Details of the Kinect Air Guitar Hack
The Kinect Air Guitar hack is an impressive demonstration of how motion-sensing technology can be used creatively. Chris O’Shea utilized the Microsoft Kinect, which is primarily known for its use in gaming, to detect his movements and translate them into musical notes. The Kinect sensor is equipped with an RGB camera and depth sensor, which allows it to capture a 3D representation of the environment. By using c++m openFrameworks and openCV, Chris was able to process the data from the Kinect and create an interactive air guitar experience.
The software setup involved several components. OpenFrameworks is an open-source C++ toolkit designed for creative coding, while openCV is a library of programming functions mainly aimed at real-time computer vision. These tools allowed Chris to track his hand movements and simulate the strumming and fretting actions of playing a guitar. The drivers used enabled the Kinect to interface with the computer, making it possible to capture and interpret the user’s gestures accurately.
Potential and Future Applications
The Kinect Air Guitar hack is not just a fun experiment; it also showcases the potential for future interactive music games and applications. Imagine a world where musicians can perform without physical instruments, using only their movements to create music. This could revolutionize live performances, making them more dynamic and visually engaging.
Moreover, the technology could be used for educational purposes. Music teachers could use similar setups to teach students how to play instruments in a more interactive and engaging way. This could be particularly beneficial for remote learning, where physical instruments might not be readily available.
Another exciting application could be in the field of physical therapy. Patients recovering from injuries could use motion-sensing technology to perform exercises that are both therapeutic and entertaining. This could make the rehabilitation process more enjoyable and less monotonous.
You can see full details of how it was done over on Chris’s website.
