I assume, that actions like turning/twisting do not work well on touch screens. you can do sliders but for somethings that may not give the correct control. I can probably turn a knob at finer increments than I can slide my finger on the screen.
- ddingus 7y agoIt is all about haptic feedback, and low latency between action and outcome. You can twist virtually with good precision. But, what is much harder is the feel, state of the knob, particularly when it is released and then gripped again. Mechanically, the structure of the knob can take some energy input, and it serves as a mechanical pivot, or fulcrum, depending on how people use a knob. Without all those physical things, people lack the complex frames of reference needed for fine, "thought is action" type control.

- ddingus 7y agoYes. And state comms. Where that input device is matters.
- jacobolus 7y ago> actions like turning/twisting do not work well on touch screens 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.
