Within a distributed live production, two locally separated markerless tracking systems where used simultaneously alongside a virtual studio. The production was based on a fully tracked actor, cyborg (half actor, half graphics), avatar, and a bot. All participants could interact and throw a virtual disc. This setup is compared and mapped to Milgram's continuum and technical challenges are described.}, language = {en} } @inproceedings{DaemenHaufsBrusbergHerder2013, author = {Daemen, Jeff and Haufs-Brusberg, Peter and Herder, Jens}, title = {Markerless Actor Tracking for Virtual (TV) Studio Applications}, series = {2013 International Joint Conference on Awareness Science and Technology \& Ubi-Media Computing (iCAST 2013 \& UMEDIA 2013)}, booktitle = {2013 International Joint Conference on Awareness Science and Technology \& Ubi-Media Computing (iCAST 2013 \& UMEDIA 2013)}, publisher = {IEEE}, address = {Aizu-Wakamatsu}, isbn = {978-1-4799-2364-9}, doi = {10.1109/ICAwST.2013.6765544}, pages = {790 -- 795}, year = {2013}, abstract = {Virtual (tv) studios gain much more acceptance through improvements in computer graphics and camera tracking. Still commercial studios cannot have full interaction between actors and virtual scene because actors data are not completely digital available as well as the feedback for actors is still not sufficient. Markerless full body tracking might revolutionize virtual studio technology as it allows better interaction between real and virtual world. This article reports about using a markerless actor tracking in a virtual studio with a tracking volume of nearly 40 cubic meter enabling up to three actors within the green box. The tracking is used for resolving the occlusion between virtual objects and actors so that the Tenderer can output automatically a mask for virtual objects in the foreground in case the actor is behind. It is also used for triggering functions scripted within the Tenderer engine, which are attached to virtual objects, starting any kind of action (e.g., animation). Last but not least the system is used for controlling avatars within the virtual set. All tracking and rendering is done within a studio frame rate of 50 Hz with about 3 frames delay. The markerless actor tracking within virtual studios is evaluated by experts using an interview approach. The statistical evaluation is based on a questionnaire.}, language = {en} }
