Have you ever used an iPod (capacitive touchpad) scroll wheel?
A good physical knob is still better, but a touch wheel can be made pretty decent.
- gugagore 7y agoI wonder if it's much easier to process the signal (at the level of measuring and interpreting the capacitances) if you assume a one-dimensional user input. I'm not sure what signal processing happens when sliding on a touchscreen/trackpad.
- sgustard 7y agoThe iPod wheel has a physical barrier acting as an affordance for your finger to trace. It certainly works better than it would just floating in space in the middle of a touch screen.
- PhasmaFelis 7y agoA iPod touchwheel can be used without looking at it. It's much more like a knob than a touchscreen display, even if it uses similar technology.
