Grab It! Design of Physical Markers for Tangible AR

This project is already assigned.


Tangible Augmented Reality (TAR) is based on the combination of physical objects with markers. For instance, a simple QR code-based marker could be added to a cube to augment it. TAR allows users to interact with the AR application by directly manipulating the object in six degrees of freedom. When used for educational purposes, TAR can intensify the application of learning content and spatial learning.

3D printing allows for the quick production of new physical objects. These objects could also feature elements that are easily recognizable by AR systems. In this way, 3D printing might allow for the development of physical markers that are especially suited for realizing TAR interactions.


The goal of this project is to investigate the feasibility of this approach. During the project, physical markers shall be created that can easily be recognized by TAR systems. Subsequently, the usability as well as user experience shall be evaluated by comparing interactions with physical markers to interactions with de-facto state-of-the-art image target-based markers. Finally, design guidelines and recommendations shall be derived.
