Haptic devices

Ultrasound haptic devices

Ultrahaptics Stratos Explore has a 256-transducer array for providing mid-air touchless haptic feedback via ultrasound. A Leap Motion camera module performs hand tracking and gesture recognition. Haptic sensations can be programmatically generated, for example on a fingertip while tapping a virtual button. We have also constructed our own scalable ultrasound haptics array (8×8 of 40 kHz actuators).

Reachin Display

Reachin display with a haptic device (e.g., Omega haptic device) provides the user with a 3D haptic user interface.

  • 3D stereo via the mirror
  • Integrating 3D vision with haptics
  • Using proxy method
  • Reachin API supporting

Touch X (3D Systems)

HaptikFabriken Polhem

  • Polhem is a haptic device with 6 degree of freedom (DoF) input and 3 DoF output haptic (force) feedback.
  • The detachable end-effector (stylus) can be easily customized and extended with other devices thanks to its independent wireless communication with the computer.
  • A pair of surgical scissors has been developed as a new end-effector​. It combines the force feedback of the cutting motion of scissors with the 3D position-based force feedback provided by the Polhem device.

Falcon (Novint)

Falcon (Novint)

  • 3-degree-of-freedom positional sensing

Omega Haptic Device

The Omega device provides 3D active force feedback for virtual objects, which has been used in many applications, such as virtual simulations, training systems and research.

•3-degree-of-freedom positional sensing
•3-degree-of-freedom force feedback
•Automatic workspace calibration
•Maximum force can reach 12 N

HaptX Glove DK2

Haptx glove is a wearable haptic device which supports hand-based motions as the input with haptic (both tactile and force) feedback.

  • Pneumatic actuation based tactile and force feedback through exo-glove with forearm anchor
  • 133 points of tactile feedback per hand
  • Exotendons apply up to 175 N of resistive force per hand / palm area
  • 30 DoF per hand with sub-millimeter precision using Vive trackers and onboard IMU
  • No occlusion, no perceivable latency, room scale movements
  • SDK with extensive support for unity and unreal with demo apps and API module


TeslaSuit is an full body suit with electrotactile full body feedback combined with body and bio tracking for interaction.

  • Tactile feedback: 80 channels of electrostimulation with Pulse Amp: 0-15 mA per channel, Pulse Width: 1-260 ms per channel and Freq: 1-300 Hz per channel (design studio + haptic primitives)
  • Connectivity: Bluetooth or WiFi
  • Motion Tracking: 10 internal sensors
  • Comes with rechargeable battery bank (needed for vest and pants 8h)
  • SDK has extensive support for unity and unreal with demo apps and API module, designer, calibration tool and much more
  • Setup and tracking requires time for each user. Suit needs to be calibrated every time (zonal) and should tightly fit the user at pressure points

Interaction devices

  • Tactile feedback devices, for example, Immersion Cyber Gloves ®
  • Force feedback devices
  • Touch input devices
  • 6 DOF input devices
  • Many other kinds of input devices

Commercial consumer lvl HMDs

We have large selection of commercial consumer level HMDs for various demonstrators and experiments.

Prototype: Superwide field-of-view (FOV) optical design for HMD

Our superwide field-of-view (FOV) optical design for HMD exceeds the full human FOV. 

Ultrasound haptics interaction

We have merged ultrasound haptics to head-mounted displays (HMD) and to mid-air fogscreens. The user can thus feel virtual objects in thin air. We have also investigated ultrasound haptics in other use scenarios such as in cars. 

Advanced visual display devices

Mid-air FogScreen

The FogScreen enables permeable, high-quality projected images hovering in thin air. Its micron-scale fog particles are dry to touch, and the screen feels just like air to the hand. The user can unobtrusively interact with the screen and walk or reach through it. The screen also stays clean and hygienic. The figure shows an example of an interactive, educational application of a small FogScreen.
