A touchscreen (or touch screen) is a type of display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device.
In computing, multi-touch is technology which enables a touchpad or touchscreen to recognize more than one [7] [8] or more than two [9] points of contact with the surface. Apple popularized the term "multi-touch" in 2007 with which it implemented additional functionality, such as pinch to zoom or to activate certain subroutines attached to predefined gestures.
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 ...
The DiamondTouch table is a front-projected interactive display that allows up to four users to sit face to face and work together on the same screen. [7] The DiamondTouch hardware enables a class of software known as "single-display groupware " [ 8 ] where collaborative work is supported by computer interfaces that allow participants to be ...
A dual-touchscreen is a computer or phone display setup which uses two screens, either or both of which could be touch-capable, to display both elements of the computer's graphical user interface and virtualized implementations of common input devices, including virtual keyboards. Usually, in a dual-touchscreen computer or computing device, the ...
Microsoft PixelSense (formerly called Microsoft Surface) was an interactive surface computing platform that allowed one or more people to use and touch real-world objects, and share digital content at the same time.
Sensacell is an interactive interface technology developed by the Sensacell Corporation. A Sensacell surface functions is an interactive touchscreen display, but on a large-scale framework. Individual tile-like modules—each containing LED ( Light-emitting diode ) lighting and capacitive sensors—are connected in an open-ended array.
Surface haptics refers to the production of variable forces on a user's finger as it interacts with a surface such as a touchscreen. Notable introductions include: Tanvas [68] uses an electrostatic technology [69] to control the in-plane forces experienced by a fingertip, as a programmable function of the finger's motion.
