HAPTICORE is our innovative haptic force feedback technology for rotary encoders in human-machine interfaces (HMI). What distinguishes us from any other rotary on the market is the ability to generate haptic feedback patterns that are fully programmable. One single rotary can create an unlimited amount of different haptic feedback patterns.

Every element of our haptic feedback, such as strength, number, and spacing of ticks, rotation resistances, or position of end stops, can be customized via software. This allows you to design perfectly tailored haptic patterns for every interaction in your user interface – all with just a single device.

We create real mechanical force feedback, no vibration, no motor – using Magneto-Rheological Fluid (MRF), a smart liquid, as the core of our HAPTICORE technology. Its use allows us to generate a superior haptic sensation to any other programmable haptic feedback device on the market.

Enabling you to build the best control concept for your product: intuitive, accurate, fast, and personalized!

Flexibility of virtual controls – Operating convenience of mechanical encoders

Contrary to traditional rotary encoders, our products can switch between different haptic force feedback patterns and do so in real-time. This allows you to tailor your haptic feedback perfectly to every menu entity in your user interface.

But why not use a touch screen?

What makes touchscreens so versatile is their ability to create custom virtual controls for every interaction. Yet, they have a fundamental limitation – you only see but do not feel what you are doing. On top of that, the application environment (water drops, fingerprints, lighting) or other influences can make touchscreens impractical or downright impossible to use.

With the HAPTICORE technology, you retain the flexibility of virtual controls but combine them with the operating convenience, especially in blind operation, of traditional rotary encoders.

How does it work?

The HAPTICORE controller contains a chamber filled with MRF, rollers, and a coil. The MRF changes its state from a liquid to a semisolid when a magnetic field is applied.

While the MRF is liquid, the rollers can rotate uninhibited, allowing the HAPTICORE to spin freely.

By applying electricity to the coil, we create a magnetic field, which changes the MRFs viscosity and stops rollers’ rotation.

By controlling the electricity’s duration and strength on the coil via software, we create our haptic force feedback patterns.

The HAPTICORE’s rotation is detected via a magnetic sensor with a finer resolution than 0.1 degrees.

Our haptic force feedback is only limited by your imagination

With our fully programmable technology, any haptic feedback pattern can be created for a more intuitive and tailored user experience. The rotation angles, rotation resistance, the number and strength of ticks per rotation can be combined and customized to your needs. But the HAPTICORE can not only adapt its haptic feedback pattern, but also the feel of every haptic sensation can be adjusted via software. Here are some examples of haptic feedback patterns:

Soft tick

Medium tick

Rough tick


Customize the number of ticks per rotation, spacing, and each tick’s strength.

Tick mode 1

Tick mode 2

Tick mode 3

Tick mode 4

Tick modes

Not only the number, spacing, and strength of ticks can be customized, but also the haptic sensation of each tick can be personalized via software.



Clockwise / Counterclockwise

Free rotation in one direction and a full rotation lock in the other, regardless of position.

Low resistance 

Medium resistance 

High resistance 

Rotation resistance

Increase the force required to turn the HAPTICORE controller. Customers in many industries associate knobs with higher resistance with quality. With our rotary, you can customize the torque required to turn the knob to your customers’ expectations.


Barrier with ticks

Barrier with increasing force


The HAPTICORE allows you to adapt the rotary’s rotation range to each interaction by placing barriers at desired angles (e.g., +/- 90°). These barriers can be combined with other haptic modes to create navigations patterns that amplify your user interfaces’ intuitiveness.

Speed adaptive feedback 1

Speed adaptive feedback 2

Speed adaptive feedback

HAPTICORE can adapt the haptic pattern not only to the application requirements but also to real-time user behavior by adjusting the haptic feedback based on the rotation speed.

Contrasting directional feedback 1

Contrasting directional feedback 2

Contrasting directional scrolling

The HAPTICORE can create different haptic feedback patterns in either direction. Any combination of ticks, barriers, or free rotation is possible.
