Distance Visualization for HMD Interaction


In this project the student should think about various methods to support the depth perception in a 3DUI scenario including an Head Mounted-Display (HMD) with a rigidly mounted finger tracking device. The finger tracking is used to track user's finger with respect to the HMD, such that the user can interact with virtual graphics shown in 3D space. As an example you might think of a virtual object (e.g. globe) and a user that might want to rotate this object. The idea is to rotate the virtual object, just like it would happen in a real-world (physical) scenario. The setup so far shows that it is hard for the user to understand when he touches the virtual object, maybe due to missing haptic and/or visual feedback.

The students' task is to think about visual methods that support user's depth perception in the above AR (Augmented Reality) interaction scenario. At least three promising methods should be implemented by the student and a scientific evaluation should be carried out to proof if these methods support the user task or not. The underlying principles in depth perception of the human eye/brain have been subject to researchers since many years, especially in the context of VR. This experiment should evaluate the applicability of some of these findings in AR scenarios in a simple way.
