Produkt- Service-System für haptische Mixed-Reality-Anwendungen

Max Pötter, TU Dresden, 2021


Despite the massive interest in haptic feedback in mixed reality, the widerange of applications, and the prosperous outlook for the mixed realitymarket, few haptic technologies are commercially available.

<marked>FingerTac<marked> is a haptic feedback thimble device

The FingerTac is a haptic feedback thimble device developed at German Aerospace Center (DLR). It enables simultaneous interaction with virtual and real elements while offering an immersive experience.

Introducing <marked>vibrotactile feedback at the fingertip<marked> without obstructing the main interaction area

The FingerTac introduces vibrotactile feedback at the fingertip without obstructing the main interaction area of the finger. Its predecessor was attached to the inner of the distal phalanx, preventing grasping and sensing of physical objects. This resulted in the need for the current configuration of the FingerTac, which enables simultaneous tactile interaction with virtual and physical objects, which is its main feature.

Make your ideas tangible

Increase <marked>interactions<marked> through

Simplify/ de-clutter

Haptic feedback can be used to substitute or relief other modalities, simplifying the interaction, making it perceived with less effort or increase the comfort.


Object interactions can be based on human interaction patterns to reach a more seamless, intuitive or emotional experience

Safety feature

Due to the seamless integration, haptic feedback can be used in critical situations without disrupting the users' perception.

Provide guidance

Haptic feedback can be used to create intuitive guiding systems by utilising multiple actuators or directional feedback.


Haptic feedback can be used to communicate brand values or brand specific characteristics.

Tailored feedback

Digital haptic feedback allows to tailor the feedback to each interaction.

Object design

Haptic feedback can lead to different product designs by replacing mechanical interfaces with surface haptics.


Haptic feedback can be utilised to make interactions more rich, prominent or to add  a certain characteristic.


Haptic feedback is great for inclusive interactions and support application for both visually or hearing impaired users.
