I always wondered if one could repurpose side-mounted fingerprint sensors (ex. Samsung Galaxy Fold) as a swipe-to-scroll mechanism.
There also used to be some lovely touchpad tech called "chiral scroll", which allowed for iPod-like scrolling. No idea where that went, patent hell?

Given how fp sensors are capacitive, this should totally be doable. Several phones (including my pixel 5) allow using rear fp sensors for opening/closing the notification shade. > "chiral scroll" Aah.. I miss that on my framework laptop. I had it on my old HP ProBook in the Synaptics settings. Chiral and (1 finger) edge scrolling were amazing. I'd suggest using ZMK/QMK and a touchpad from mouser if anyone wants to DIY one today.
- imp0cat 2y agoMy last Samsung with a back-mounted fingerprint sensor (A40) could do that (there was an option in the settings to enable scrolling with the fingerprint sensor).
