Development of a frequency-separated knob with variable change rates by rotation speed
We applied the principle of frequency separation to the design of knobs and related it to the study of control-display gain. We developed a prototype of a speed frequency-separated knob that shows change rates varying depending on its rotation speed. We conducted two experiments to examine whether the newly developed knob enhances users' task performance. The results showed that the newly designed speed frequency-separated knob was effective in enhancing task performance. The results can offer useful information when developing guidelines for designing a knob.
