Laboratories

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.

Touch X (3D Systems)

Haptic (force-feedback) devices can provide force to users, for simulating the touch feeling of virtual objects. Laboratory 1074 haptic device.

Touch X (3D Systems)

6-degree-of-freedom positional sensing
3-degree-of-freedom force feedback
Automatic workspace calibration
Compact footprint, quick installation and ease-of-use

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.

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

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

{ __( ‘Manage my cookie choices’, ‘the-dustpress-theme’ ) }

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.

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.
