The ultimate keyboard - made with light?
Chicago (IL) - After countless prototype demonstrations, the virtual keyboard finally has made it into production. Several companies worked on the development of the technology, but only one firm appears to have cleared all hurdles to be able to offer a stable commercial product.
A full-size keyboard for your cell phone or PDA everywhere you go, integrated in every device - too good to be true? For about four years, Canesta has been promoting its electronic perception technology, consisting of 3D camera with light source as well as sensors being able to recognize and interpret movements within the camera's sight. The flagship application was a keyboard that was projected to the space in front of a PDA offering users an alternative to folding keyboards or handwriting on a PDA.
Similar projects have been underway at a number of other companies, including Nokia. The foundation of most virtual keyboards was developed by VKB, a company based in Israel that licensed the technology base to interested organizations. Firms such as Canesta have been quiet about their technology in recent months and even removed content relating to their research from their web sites. Instead, Canesta regiustered a range of patents and now sells its 3D sensor technology as development kit to developers.
Just when we started to believe a virtual keyboard would remain science-fiction, Hutchison Harbour Ring (HHR) has begun manufacturing a commercial version of the keyboard. HHR is a subsidiary of Hutchison Whampoa, Hong Kong-based company with the hands of its 170,000 employees in telecom technologies, real estate, retail and manufacturing and energy supply.
