Nescher, Thomas and Kunz, Andreas M. (2012): Analysis of Short Term Path Prediction of Human Locomotion for Augmented and Virtual Reality Applications. In: Proceedings of the 2012 International Conference on Cyberworlds CW 2012 September 25-27, 2012, Darmstadt, Germany. pp. 15-22.

“When human locomotion is used to interact with virtual or augmented environments, the system’s immersion could be improved by providing reliable information about the user’s walking intention. Such a prediction can be derived from tracking data to determine the future walking direction. This paper analyses how tracking data relates to navigation decisions from an egocentric view in order to achieve a reliable and stable path prediction. Since tracking data is noisy, a smoothening is required that eliminates oscillations while still recognizing trends in human locomotion. Thus, we analyze different approaches for path prediction, determine relevant setting values, and verify the results by a user study. Results indicate that robust short term prediction of human locomotion is possible but care must be taken when designing such a predictor. ”

Nescher, Thomas and Kunz, Andreas M. (2011): An interactive whiteboard for immersive telecollaboration. In Lecture Notes in Computer Science, pp. 1-10.

“In this paper, we present CollaBoard, a collaboration system that gives a higher feeling of presence to the local auditory and to the persons on the remote site. By overlaying the remote life-sized video image atop the shared artifacts on the common whiteboard and by keeping the whiteboard’s content editable at both sites, it creates a higher involvement of the remote partners into a collaborative teamwork. All deictic gestures of the remote user are shown in the right context with the shared artifacts on the common whiteboard and thus preserve their meaning. The paper describes the hardware setup, as well as the software implementation and the performed user studies with two identical interconnected systems. ”

Kunz, Andreas M., Nescher, Thomas and Küchler, Martin (2010): CollaBoard: A Novel Interactive Electronic Whiteboard for Remote Collaboration with People on Content. In: 2010 International Conference on Cyberworlds - Cyberworldds 2010 October 20-22, 2010, Singapur, Singapore. .

“In this paper, we present a device called _CollaBoard_. It was developed in the context of ongoing CSCW research efforts in developing groupware that mediates remote collaboration processes. CollaBoard combines video- and data-conferencing by overlaying a life-sized video showing the entire upper body of remote people in front of the displayed shared content. By doing so, CollaBoard shows pose, gaze, and gestures of remote partners, preserves the meaning of users_ deictic gestures when pointing at displayed shared artifacts, and keeps shared artifacts editable at both conference sites. For this, a new whiteboard software is also introduced, which allows a real-time synchronization of the generated artifacts. Finally, the functionality of two interconnected CollaBoard prototypes was verified in a usability assessment.”

Hofer, Ramon, Nescher, Thomas and Kunz, Andreas M. (2009): QualiTrack: Highspeed TUI Tracking for Tabletop Applications. In: Gross, T. (ed.) Proceedings of Interact 2009 August 24-28, 2009, Uppsala. pp. 332-335.

“In this paper, we present a new technology to track multiple active Tangible User Interfaces (TUI) on a projection table. We use a commercial high speed infrared tracking camera with modified firmware. With a special tracking method, we reach update rates of up to 250 Hz with low latencies. At this tracking rate, we are able to track the position, state and the orientation of more than 10 active TUIs on the table. For this, we use specified bit codes which are transmitted by the devices. We developed dedicated hardware (SyncUnit) and software to keep the devices and the high speed camera synchronized. The system of camera, SyncUnit, and devices is fully hardware controlled and delivers event coded tracking data for further usage in interactive applications. ”
