Active haptic renderings need not only mimic the physical characteristics of a mechanical control such as a knob or slider. They must also elicit a comparable subjective experience from a human who uses the physical control. We compare the results of automated and human captures of 4 salient static and dynamic physical parameters for 5 mechanical test knobs. The automated captures were accomplished using our custom rotary Haptic Camera tool. Human captures were accomplished through user studies in which users matched active haptic renderings to passive mechanical test knobs by adjusting the parameters of the model for the active knob. Both quantitative and qualitative results from the experiments support the hypothesis that the renderings evoke a subjective experience similar to the mechanical knob.
