Cirque trackpad news
Cirque trackpad in action, build log, and 3D-printable holders – shared by leo_beekeeb and milkycowdan.
Published July 10, 2022
We've seen some projects with the Cirque touch sensor recently (Chunky iterations, Fusion, Rocksolid), and there were two interesting posts about this trackpad last week.
Daniel Kao aka milkycowdan shared a demo video after posting his Cirque implementation (back in May this year).
Was requested to show a video of the trackpad in use. […] I've switched over to a 40mm with flat overlay because hover issues on curved overlay were too annoying to deal with – milkycowdan.
The video demonstrates inertial cursor and circular scroll. Scroll is started with a touch on the outer ring; a touch starting on the side closer to keys triggers vertical scroll, and touch starting on the other side triggers horizontal scroll.
Daniel adds that the bigger active area is also easier to find since the curved overlay had thick inactive areas around the outer perimeter. He found 3x attenuation to be best, rather than the 4x suggested by Cirque sample code.
