An optical mouse is a computer mouse which uses a miniature camera and digital image processing to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse and its need for frequent cleaning. The earliest optical mice detected movement on prepared surfaces, however they never gained ...
A pointing stick (or trackpoint, also referred to generically as a nub, nipple or clit) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the ...
The Mouseless is a proposed input device for personal computers. A prototype Mouseless, designed by Pranav Mistry of the MIT Media Lab. [1] Mouseless replaces conventional hardware mouse with a set of infrared laser strobe, an infrared camera and image recognition software. The laser beam is optically split into a wide beam illuminating an ...
A typical wireless computer mouse. A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a ...
A laser or beamer projects visible virtual keyboard onto level surface. It is a modern input device. A sensor or camera in the projector picks up finger movements. Software converts the coordinates to identify actions or characters. [1] Some devices project a second (invisible infrared) beam above the virtual keyboard.
Definition. 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 ...
Today we feature a study that makes good on science envisioned by H.G. Wells over 100 years ago in "The Invisible Man". Applying a food-safe dye that absorbs light onto the skin of a mouse makes ...
Touchpad. A touchpad or trackpad is a type of pointing device. Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to 2D motion, to control a pointer in a graphical user interface on a computer screen.
