Finger Tracking - TechViz - Touch parts of your 3D model

Finger Tracking

Use your hands in your Virtual and Augmented Reality experience

Finger tracking enables users to see virtual avatars of their hands, mimicking with precision the movements of hands and fingers. This is key in many use cases to truly interact with the model and even touch* virtual objects with the millimeter-accuracy of the fingers’ position and movements.

*touch = you can feel the touch using haptic feedback, depending on the selected device. A visual feedback is also possible through 3D collision detection.

Feel each part of your model at your fingertips

TechViz finger-tracking allows you to add external sensors such as tracking gloves and force-feedback devices. While interacting with your CAD model without controllers, you will be able to feel vibrations or create a physical resistance when grabbing virtual objects.

Key advantages

Low-friction and high-fidelity interactions in VR

Visualize a more accurate representation of your fingers and observe collisions with products with sound, colors and haptic feedback (with a compatible device).

More realistic simulations in the virtual world

Enhance the realism of your simulations with interactions that closely mirrors real life and a deeper sense of presence and immersion.

Quick to setup, simulate multiple variants

Store and evaluate them again whenever you want.

Use Cases

Better ergonomic and reachability studies

Evaluate if users can operate in the real environment and access the controls. It can also be used to measure the time to perform a given task.

Cockpit design

Analyze reachability and accessibility of the different controls. Check ergonomics of the onboard HMI. Using haptic feedback, the fully-immersive experience is even more realistic, offering more accurate customer perception.

Assessment of 2D interfaces within 3D models

Insert non-3D elements within your 3D CAD models to assess in-car human machine interfaces (HMI).

Fully immersive design reviews

Participate in VR project reviews with finger tracking to speed up design-to-market processes – even with participants that are new to VR

How does finger tracking work?

Finger-tracking happens when the augmented and virtual reality headset, external cameras or finger-tracking sensors can track your hand and finger’s position, pace, and orientation. The tracking data is then analyzed by your VR software into a real-time representation of your fingers and your interactions with the CAD model inside the virtual world.


The AR/VR system natively includes Finger-tracking

The tracking originates from your head-mounted device’s cameras and is called inside-out tracking. It uses the difference in pixels to determine your fingers’ movements.

This is the case for several VR headsets like HTC Vive Focus 3 and Meta Quest 2.


The AR/VR system relies on Ultraleap SDK

The immersive virtual reality system features Ultraleap’s optical tracking software.

It can either be integrated inside the head-mounted display’s cameras (like in Varjo XR-3 and VR-3) or displayed through an external module (such as Pimax vision 5K and 8K and Pico Neo 3)


The AR/VR system relies on an external tracking system

For specialized use cases and older VR systems, you will need a tracking sensor device.

TechViz Finger Tracking is compatible with the professional devices: ART Finger Tracking, Vibro Tactile Finger Tracking, CyberGlove and UltraLeap.
