Hapticore ®

Haptic feedback, software-controlled & in real time

The first rotary encoder in the world
with fully programmable haptic feedback

Haptic feedback, software-controlled, and in real time:

this is Hapticore®, the world’s first fully programmable haptic force feedback technology in man-machine interfaces - based on our MRF technology.

Universally applicable


What distinguishes our products from other rotary encoders in the market is the unique possibility to generate every conceivable haptic feedback pattern by means of software.

Our products combine the flexibility of virtual controls with the tactile feedback of traditional encoders:

one single rotary wheel can produce an unlimited number of different tactile sensations - thus, we are able to create an input device with perfectly tailored haptic feedback patterns for each and every interaction in your user interface.

Hapticore ® technology


The core of the Hapticore ®technology is magnetorheological fluid (MRF).

By means of this technology we can generate a better haptic feel than with any other programmable haptic feedback device in the market.

The function of Hapticore ®


Hapticore®push-turn actuators contain a chamber filled with MRF, rollers, and a coil. As long as the MRF is liquid, the rolls can turn without obstruction so that Hapticore®can rotate freely.

An electric current applied to the coil generates a magnetic field at the coil which changes the viscosity of the MRF, i.e. the latter becomes solid. As a result, the rotation of the rollers is stopped. By controlling the duration and strength of the current on the coil via the software, we produce our haptic force feedback patterns.

Thus, all feedback elements such as strength, the numbers and intervals of ticks, turning resistance, or the position of end stops can be freely customized.

This is how you can design perfectly customized haptic feedback patterns for each and every interaction in your user interface by means of only one device.
