Project involvement:

• Organic Interfaces
  • DRAGON - a novel interaction technique for frame-accurate navigation in video scenes
  • PocketDRAGON - saving screen real estate when scrolling through videos by using DRAGON for the iPhone
  • DRAGONEye - a real-time version of DRAGON that does not need pre-processing and is robust agains object occlusions
  • TWEND: Twisting and Bending as new Interaction Gesture in Mobile Devices
  • Fly: an organic presentation tool
• Personal Orchestra (Audio Processing)
• PhaVoRIT - a Phase Vocoder for Real-Time Interactive Time-Stretching - Diploma thesis

Side projects:

• The i10 diploma thesis template is now ready for download!
  • Please report to me any problems you might encounter while using the template.
• Working on a OmniGraffle Stencil file (896.72 Kb) containing some of the devices we have in the MediaSpace.
