Mutual capacitance allows multi-touch operation where multiple fingers, palms or styli can be accurately tracked at the same time. [10] Self-capacitance sensors can have the same X-Y grid as mutual capacitance sensors, but the columns and rows operate independently. With self-capacitance, current senses the capacitive load of a finger on each ...
Back side of a Multitouch Globe, based on projected capacitive touch (PCT) technology Schema of projected-capacitive touchscreen Projected capacitive touch (PCT; also PCAP) technology is a variant of capacitive touch technology but where sensitivity to touch, accuracy, resolution and speed of touch have been greatly improved by the use of a ...

Video demonstrating the operation of a touch-sensitive lamp A touch-sensitive lamp is a combination of a lamp and a touch switch. They act on the principle of body capacitance, activated by human touch rather than a flip, push-button, or other mechanical switch. They are popular as desk and nightstand lamps. Touch-sensitive lamp switches may be ...
Projected capacitance is used to allow interactivity through any non-metallic surface and involves the relationship between a conductive pad and a third object. In touch screen applications, the third object can be a human finger. Capacitance forms between the user's fingers and the wires in the conductive pad.
In 1999, Gary Zalewski patented a system of moveable children's blocks containing sensors and displays for teaching spelling and sentence composition. [ 13 ] Tangible Engine is a proprietary authoring application used to build object-recognition interfaces for projected-capacitive touch tables.
