The Atlantic has pointed out a video of a tech demonstration from the early 90s:
Today, we are living the dream of the nineties — at least when it comes to technology. The virtual realities we imagined are now available in toy stores. Microsoft’s $150 Kinect, a depth and motion-sensing camera originally designed for video games, has become a ubiquitous hackable interface for countless developers, musicians, and artists. Long before the Kinect powered musical performances like this, however, Vincent John Vincent and the 20th Century Kid performed this amazing demonstration of pioneering gesture-controlled video technology, below.
Worth watching for 90sness - Weird Al Yankovic introduces the demo along with some robotic presenter:
The video description is worth reading as well:
This is the future of Kinect Musical Performance. Vincent John Vincent invented video gesture control virtual reality with Francis MacDougall in 1986. By 1991 they had a fully dynamic immersive video gesture control virtual reality system. Vincent started performing around the world in 1986. He created a whole new genre of performance technology and hundreds of virtual performance instrument scenes, including musical scales, soundscapes, virtual drum kits, virtual juggling, virtual dance and a world of other creative landscapes. He is the President and Co-Founder of GestureTek, the worlds leading Video Gesture Control company. They and their company, Gesturetek, wented on to invent may more video gesture control products, including interactive surfaces and 3D video gesture control (2000), which is the technology behind the Kinect.. GestureTek holds over 18 patents, and has licensed patents and technology to Microsofy for the XBOX, and to Sony for the PlayStation, etc. www.vjvincent.com , www.gesturetek.com
