- acct-litter-al 1y agoI once put some aluminum duct tape completely over the touch pad of an old laptop to see what would happen. Turns out it induced enough "eddy currents" to make the mouse move around the screen without me touching it--in a way, visualizing the currents! I connected the foil to ground using a small strip of the tape to the ground metal of a USB port on the side and it disabled the touch pad.
- acct-litter-al 1y agoLooking back, it would have been interesting to code up a program to record the movement of the mouse as a trail of pixels...
- KeplerBoy 1y agoIf you ever want to do this keep in mind to reconfigure the mouse as a digital pointing device (tablet like), otherwise the mouse acceleration will mess up your position measurement.

- svnt 1y agoNo, you need roughly a small human's worth of ground mass for most capacitive touch sensors to register a touch.
- bigyikes 1y agoTape a wire to the trackpad and hold the wire?
- stavros 1y agoHow do capacitive pens work?
- svnt 1y agoYou electrically couple to the pen, unless they are active devices, in which case they generate a signal.
- stavros 1y agoThat can't be, they work with gloves and things. My gloves even have a thing at the end that works with the touchscreen.
- svnt 1y agoYou’ll have to be more descriptive for me to have any hope of answering. If by your gloves have a thing at the end you mean a patch of special fabric, yes, that fabric conducts from your skin to the screen.

- sanex 1y agoIf you don't have ground human presumably you can substitute ground beef or ground turkey.
