Aug 05, 2010· I'm not a technical guy, but I do know that the iPad screen works by sensing the electrical capacitance of your fingers. It is not a pressure-sensitive screen like those used in some smartphones, PDAs and gaming devices that use a traditional stylus.
The big drawback of capacitative screens is that they don't work well, or at all, when the user's fingers are covered by electrically insulating material, like gloves.
Unlike the screen on your iPad, a resistive screen will work with anything. It doesn't matter if you are wearing gloves or are using a regular old pen (not the ink nib!) to input touches. Most resistive touch screens that you find in the wild do not support multi-touch, but it is possible to do with this technology.
Chemeli, The chip that controls the touch screen "scans" along, selecting in turn each column of the x axis, then reads a signal from the y axis that is (roughly) zero if not touched, or a number proportional to the height if there is a touch.

When you touch the screen, you interrupt the sound beams and absorb some of their energy. The screen's microchip controller figures out from this where exactly you touched the screen. ... How Does a Touch Screen Work? by Leon Gray. Gareth Stevens, 2014. A …
How does the resistive touch screen work? When you press your finger on a resistive screen, the top, flexible layer touches the bottom one, and the interruption in the electrical current is noted by the device, and it calculates the precise location of the point of contact.
Resistive touch is one of the cheapest touch technologies out there. A resistive touchscreen responds to pressure and doesn't care what object applies the pressure. A finger, glove or stylus will all work. Swiping and multi touch do not work, because this technology only registers one touch point.

A touchscreen, or touch screen, is an input device and normally layered on the top of an electronic visual display of an information processing system.A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work ...
How do touch-sensitive screens work? With a little electrical help from the human body, touchscreens can tell where our fingers are pointing… By Sajan Saini. Touchscreens have used a variety of techniques over the last two decades to detect the placement of a finger on a screen — ranging from mechanical, optical, and electrical sensing.
When you touch a conductive material to this screen, some of that electrical charge transfers over to whatever is touching it. But the material must be conductive or the device won't register a touch. In other words, you can use anything to touch a resistive screen to register a charge but only conductive material will work on a capacitive system.
A resistive system registers a touch as long as the two layers make contact, which means that it doesn't matter if you touch it with your finger or a rubber ball. A capacitive system, on the other hand, must have a conductive input, usually your finger, in order to register a touch.
The touch screen responds to touch, but the cursor does not move as expected or is more than half an inch (1.3 cm) away from the point of contact. Your touch screen might …
