Is there an HMI solution that is equally intuitive for everyone to use?
The "placeable rotary knob" from the pre-series development stage can be used on different user interfaces (touchscreen, center console, door control module). This enables flexible multi-modal operation.
It can also be ordered multiple times so that the individual rotary knobs remain in their respective operating locations - as if they were permanently installed.
The 360-degree rotary push knob is supplied with either active or passive haptic feedback. It can be placed on different surfaces such as leather, wood, glass or plastic. A wide variety of personalization options are also available: gold-plated, studded with rhinestones or classically simple. If you prefer to use a pure touchscreen, you can simply remove the knob and hide it in the glove compartment.
The car of the future is versatile in terms of the interior, dashboard and center console. In autonomous driving, the multimedia display doubles in size and the steering wheel folds away. Functions are selected via integrated control elements, touch screen and touchpad with active, haptic feedback. Smart surfaces have integrated control elements.
Preh presented innovative automotive control systems (HMI) for the center console (center stack) at the IAA. Central display contents can be moved to the instrument cluster using gesture control. When functions are selected on the touch screen, you get visual and haptic feedback. A rotary knob connects conventional, mechanical operating elements with the digital world of displays. Various functions can be accommodated in small spaces.
At the IAA, Preh Automotive showed new possibilities of integrating 'haptic landscapes' into a touchscreen. Up to now, the driver has not received any feedback from the system via a touchscreen when performing functions. The solution presented provides haptic feedback by pressing vibrating buttons and sliders on the screen. The driver thus receives noticeable feedback from his selection of functions.
Preh shows new ways in HMI design with a vehicle door operating module concept. The module has a completely closed surface. Icons for function selection become visible when the hand approaches. They can also be felt through tactile contours and active haptic feedback confirms each function selected.
Thanks to specially developed actuator and sensor technology, there are no moving parts. The operating module can thus be inserted into the vehicle door without a gap. Individual design of the perceptible contours and use of different surface materials are possible.
