How It Works

Some of the companies making these solutions and devices include Canesta, Samsung, Senseboard Technologies, Virtual Devices (Figure 46-1), and VKB. Canesta has developed an “electronic perception technology” that can form electronic images of nearby objects in three dimensions. Instead of the flat, two-dimensional image created by digital cameras and digital videos, the Canesta technology can determine the distance of every pixel in the image in real time, giving it the ability to “see” objects and to enable applications to take appropriate actions based upon this information. The solution has widespread applicability beyond virtual keyboards; it could help computers see the physical world and react to it. Some sample applications include vehicle control, airport security, and national security, among many other possibilities.
