Profile

I am currently a doctoral candidate in the department of computer science supervised by Prof. Dr. Reinhard Klein (University of Bonn, Institute of Computer Science II -- Computer Graphics) and Prof. Dr. André Hinkenjann (BRSU, Institute for Visual Computing). My doctoral project is titled "Natural two-handed interaction for virtual environments".

The major goal of this work is to facilitate manipulation (select, rotate, translate, deselect) of virtual objects in virtual environments (e.g. a CAVE or a PowerWall) in a way we are used to manipulate real objects. I.e. to grasping (select) the virtual objects with one's own hands as if it was a real object, interact with it (rotate, translate) and release it (deselect). Especially in large-volume virtual environments this is realised via mediating devices such as game controllers (e.g. Wii-Mote) or special input devices.

Challenges:

  • Tracking of bare hands considering the high complexity/dimensionality of hand motions.
  • Virtual grasping, detection of object (de)selection and transformation, i.e. answering the following questions: "When has an object been grasped, when has it been released and what was done with the object?".
  • Exploration of multi-modal feedback in order to provide means of orientation in the virtual work and the current status of the interaction.

My Phd project is supported by the 2014 scholarship from the equality body of Bonn-Rhein-Sieg University.
