Wait how can he use a smartphone since they use your body heat to determine where you tapped.

Because they don't

Uhhh, that's not how touchscreens works.

Actually, that's how better touchscreens work. My old phone could anything touching it with enough pressure, be it a tablet pen on my finger....and would go nuts whenever I pulled it out to use it in a light rain, ing every single drop as a press or long press.

My new phone, while not expensive, is overall better, and only s skin (and hopefully certain pens designed for it). The only logical difference between the two is the temperature associated with your skin. Because they do make thermal sensors that aren't too expensive.

No, no they don't... unless I'm missing something REALLY new. Most modern touch screens are capacitive touchscreens, which, to put it in simple , have have a field of electricity running through them, and human skin touching it disrupt the electrical field, making it the 'touch'. Wearing gloves and getting anything else non-conductive in-between shields your fingers hence why it doesn't work with gloves and whatnot.

Older touchscreens are resistive - basically two sheets of material with sensors between then. Putting force on the screens activates the sensor, so it works with anything.

I assume some devices are a mix of both since you can use both your fingers and a stylus. But no, heat does not factor in to it. It's your skins electrical properties that make some touchscreens work.

~the more you know~

Actually, stylus pens nibs have conductive rubber and a coil with a chip to mimic a finger, so scratch the last part.
