The Science Behind Touchscreen Gloves
Touchscreen gloves are commonly used with smartphones, tablet computers, human machine interfaces (HMIs) and other touchscreen devices. They look and feel like regular gloves, but there's one unique feature differentiating them from traditional gloves: They work with all touchscreen devices.
It's no secret that regular gloves aren't compatible with all touchscreen devices. If you own a capacitive smartphone, for example, you probably won't be able to control it while wearing regular gloves. Touchscreen gloves differ in the sense that they can be worn while using a capacitive smartphone or device.
Capacitive Touchscreen Technology
To better understand how touchscreen gloves work, you must look at capacitive touchscreen technology. There are nearly a half-dozen different types of touchscreen technologies, the two most common of which include resistive and capacitive. Resistive touchscreen technology uses pressure to detect touch commands. When you press the display interface, you'll inadvertently push the top layer into an underlying bottom layer. The resistive device then identifies the location where these two layers met, processing it as the location for your touch command.
Capacitive touchscreen devices work in a completely different way. Rather than identifying touch commands using pressure, they rely on capacitance. Capacitive touchscreen devices feature a top layer of glass that's coated with a transparent conductive material, usually indium tin oxide (ITO). When you press the display interface, your finger will absorb some of the electricity flowing through the conductive material, which the device uses as the location of your touch command.
