A Theoretical Framework of Haptic Processing in Automotive User Interfaces and Its Implications on Design and Engineering

“…How are the haptic impulses interpreted?). This separation can also be found in Bubb et al (2015). We will follow a psychological view, where we differentiate between search and confirmation haptics.…”

“…Regarding hedonic aspects, surface haptics refers to the use of haptics to evoke aesthetical evaluations. For example, certain surface materials are used to underline certain associations, such as perceived quality, coziness, or warmth, connected to the car (Bubb et al, 2015, p. 285). However, in automotive user interfaces surface properties such as joints, edges, recesses, other surface geometries, and textures can also have a clear functional reason, for instance, to support drivers in the blind operation of car interfaces to free up visual resources for the primary driving task.…”

“…Within confirmation haptics, there is a differentiation between translational and rotational control elements (Bubb et al, 2015). These mainly involve orthogonal movements, such as button presses, or rotary movements (turning knobs).…”

“…By turning the knob, the mechanics snap into a detent—producing a click feeling (Reisinger, 2009). The haptic feedback is defined by specifically designed force-displacement-curves (Kühner, 2014; Bubb et al, 2015). Figure 3 depicts characteristic haptic curves of translational and rotational control elements.…”
