Max completed his PhD on capturing the expressiveness of touch on interactive surfaces at the Media Computing Group under the supervision of Prof. Dr. Jan Borchers in 2013. To find out what he did next, check out our alumni page.
I was a PhD student at Media Computing Group from September 2008 to December 2013. I was conducting research on how to better capture the expressiveness of touch on a variety of interactive surfaces. My project heritage can be found here (internal access only).
Touch interfaces provide great flexibility in designing an UI. However, the actual experience is often frustrating due to bad touch recognition. We saw that the relative location of the predecessor of a touch has a significant impact on the orientation and position of the touch ellipsis. We exploited this effect on an off-the-shelf touch display and showed that with only minimal preparation the touch accuracy of standard hardware can be improved allowing better recognition rates or more UI components on the same screen.

3D Displays can be controlled using direct manipulation. This, however, introduces problems as the "direct" notion means that our object should stick to our fingers during interaction. However, on a viewer-centric display, head movements will also translate the object. We compared different methods to cope with these constrains.

TaPS Widgets enable private spaces on Tabletops using a tangible widget. TaPS widgets do not need wearable hardware, scale well with additional users, require only low-cost hardware, and do not suffer from concurrent access conflicts.
