Dr. Seifert has crownd his contributions and work for the institute of media informatics with a dissertation - title Mobile mediated interaction with pervasive displays - in 2015. The pdh thesis is available here for download.


Hover Pad: Interacting with Autonomous and Self-Actuated Displays in Space

In this work, we investigate the use of autonomous, self-actuated displays that can freely move and hold their position and orientation in space without the need for users holding them at all times. We illustrate various stages of such a display’s autonomy ranging from manual to fully autonomous, which – depending on the tasks – facilitate the interaction. Further, we discuss possible motion control mechanisms for these displays and present several interaction techniques made possible by such displays. We designed a toolkit – Hover Pad – that enables exploring five degrees of freedom of self-actuated and autonomous displays and the developed control and interaction techniques.
