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).
These guidelines are less relevant for the bulk of modern touch devices which use capacitive or resistive touch technology. [ 101 ] [ 102 ] From the mid-2000s, makers of operating systems for smartphones have promulgated standards, but these vary between manufacturers, and allow for significant variation in size based on technology changes, so ...
In 1976 a new x-y capacitive screen, based on the capacitance touch screens developed in 1972 by Danish electronics engineer Bent Stumpe, was developed at CERN. [ 1 ] [ 17 ] This technology, allowing an exact location of the different touch points, was used to develop a new type of human machine interface (HMI) for the control room of the Super ...

Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).
Some capacitive touch-screens can detect the size of the touched area and the pressure used. [123] Since mid-2010s, most tablets use capacitive touchscreens with multi-touch, unlike earlier resistive touchscreen devices which users needed styluses to perform inputs.
Capacitive (also called passive) styluses emulate a finger by using a tip made of rubber or conductive foam; or metal such as copper. They do not need to be powered and can be used on any multi-touch surface that a finger can be used, typically capacitive screens that are common in smart phones and tablet computers. Stylus tips made of rubber ...
HTC opted for resistive technology for the touchscreen. The reason cited by Horace Luke, HTC's Chief Innovation Officer, was that the resistive touch screen is better for Asian character recognition. [13] However, the buttons beneath the screen, as well as being pressable buttons, have capacitive touch sensitivity.
