Turn laptop touchpad into a drawing pad in Windows

Solution 1:

Press and hold with the left or right hand, draw with a stylus.

Solution 2:

I just use my fingers. If you have enough patience, it'll work eventually. I usually hold down with my left hand and draw with my right - do whatever is comfortable for you. A website I use is aggie.io , but you can use paint or whatever is convenient for you. I inserted an example of a drawing I did.

Solution 3:

If you're using Asus/RoG, you can probably be provided with Asus Touchpad Handwriting software. You should be able to find generic software/libraries like this (Sourceforge Link) or this GitHub repo as well to achieve the same

You can use this for adding signature to email or documents as well. It works surprisingly well

Note that to save what you have drawn on the touchpad, you need to take screenshot and save it. Simplest option is to use OneNote clipping tool or Windows 10 inbuilt screenclipping Win+Shift+S
