Virtual touch screen technology can also be applied to turn non-touch displays into interactive, touch-capable surfaces using a Kinect sensor in combination with a projector. [14] This type of application allows virtual touch technology to enhance personal display usage as well as better communication and presentation of data to be used in ...
OmniTouch is a wearable computer, depth-sensing camera and projection system that enables interactive multitouch interfaces on everyday surface. Beyond the shoulder-worn system, there is no instrumentation of the user or the environment.
Users can press the buttons directly, with their fingers, much like a touch screen. Skinput is an input technology that uses bio-acoustic sensing to localize finger taps on the skin. When augmented with a pico-projector, the device can provide a direct manipulation, graphical user interface on the body.
The resulting resistive technology touch screen was first shown on the World's Fair at Knoxville in 1982. [20] 1982 MULTI-TOUCH CAMERA - Multi-touch technology began in 1982, when the University of Toronto's Input Research Group developed the first human-input multi-touch system, using a frosted-glass panel with a camera placed behind the glass.
In the old technology, the computer's "vision" was created by a near-infrared, 850-nanometer-wavelength LED light source aimed at the surface. When an object touched the tabletop, the light was reflected to multiple infrared cameras with a net resolution of 1024×768, allowing it to sense, and react to items touching the tabletop.
TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of ...
Many electronic visual displays are informally referred to as touch screens. Starting in the early 2000s, flat-panel displays began to dominate the industry, as cathode-ray tubes (CRT) were phased out, especially for computer applications. Starting in the mid 2010s, curved display panels began to be used in televisions, computer monitors, and ...
In 2002, start-up company Canesta developed a projection keyboard using their proprietary "electronic perception technology." [2] [3] [4] The company subsequently licensed the technology to Celluon of Korea. [5] A proposed system called the P-ISM combines the technology with a small video projector to create a portable computer the size of a ...
