Capacitive sensing. In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric constant different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity ...
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. Touchscreens are commonly found in smartphones, tablets, laptops ...
Projected capacitance touchscreens and keypads. Single wire plot for 32 input, diagonally wired, projected capacitance touchscreen film. 32 input diagonally wired touchscreen These do not use diodes but rely on the change in capacitance between crossing conductive tracks to detect the proximity of one or more fingers through non-conducting ...
Resistive touchscreen technology works well with almost any stylus-like object, and can also be operated with gloved fingers and bare fingers alike. In some circumstances, this is more desirable than a capacitive touchscreen, which needs a capacitive pointer, such as a bare finger (though some capacitive sensors can detect gloves and some gloves can work with all capacitive screens).
3M Expands Surface Capacitive Touchscreen System Offering Polished-like touchscreen helps enhance interactive high-definition 3D graphics METHUEN, Mass.--(BUSINESS WIRE)-- As an innovation leader ...
Touch switch. A touch switch is a type of switch that only has to be touched by an object to operate. It is used in many lamps and wall switches that have a metal exterior as well as on public computer terminals. A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor.
Visualplanet Ltd specialises in the manufacture and global distribution of projected capacitance interactive touch screen foils, which are designed to be used in a wide variety of Touch Screen applications from through-window touch to direct integration into LCD Screens.

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. For example, the present shoulder-worn implementation allows users to manipulate interfaces projected onto ...
