Abstract [en]

Motion capturing technology has been used for quite a while and several research has been done within this area. Nevertheless, we discovered open issues within current motion capturing environments. In this paper we provide a state-of-the-art overview of the addressed research areas and show issues with current motion capturing environments. Observations, interviews and questionnaires have been used to reveal the challenges actors are currently facing in a motion capturing environment. Furthermore, the idea to create a more immersive motion capturing environment to improve the acting performances and motion capturing outcomes as a potential solution is introduced. It is hereby the goal to explain the found open issues and the developed ideas which shall serve for further research as a basis. Moreover, a methodology to address the interaction and systems design issues is proposed. A future outcome could be that motion capture actors are able to perform more naturally, especially if using a non-body-worn solution.

Abstract [en]

Current and future animations seek for realistic motions to create a perception of authentic and human-like animations. A technology widely used for such purposes is motion capture. Therefore, to create such human-like animations, motion capture actors enrich the movements of digital avatars with realistic and believable motions and emotions.

Acting for motion capture, as it is performed today, does not provide a natural acting environment. This is mostly because motion capture actors do not see and feel the virtual environment they act for, while acting. In many cases this can result in unnatural motions such as stiff looking and emotionless movements.

To investigate ways to solve this, we first identify the challenges actors are facing as well as concepts to support a motion capture actor. Furthermore, we discussed, how the task of supporting motion capture actors was approached and which factors were discovered to provide support when designing and im- plementing a solution. Initial prototypes have been created to address the men- tioned issues and to find suitable solutions to support and immerse motion cap- ture actors during their performance. For this thesis, one goal was to conduct research by focusing on the question: What are the experiential qualities of immersion in an interactive system to create an immersive acting environment that supports motion capture actors.

The developed application provides a flexibility to set up and modify digital assets and scenes quickly and with an easy to use interface. Furthermore, the prototype helps to provide an understanding on which hardware and software prototypes can be designed and used to build an immersive motion capture environment. The built prototype allows to investigate user experiences, user tests and the satisfaction of users and their effects on motion capture acting.

Abstract [en]

Current and future animations seek for realistic motions to create an illusion of authentic and believable animations. A technology widely used to support this process is motion capture. Therefore, motion capture actors are used to enrich the movements of digital avatars with suitable and believable motions and emotions.

Acting for motion capture, as it is performed today, is a challenging work environment for actors and directors. Short preparation times, minimalistic scenery, limited information about characters and the performance as well as memorizing movements and spatial positions requires actors who are trained and able to highly rely on their acting and imagination skills. In many cases these circumstances can lead to performances with unnatural motions such as stiff looking and emotionless movements, as well as less believable characters. To compensate this, time-consuming repetitions of performances or post-processing of motion capture recordings is needed.

To improve this, we explore the possibilities of acting support and immersion through an interactive system supporting motion capture actors during their performances. In this process, we use an approach that combines research methods from interaction design and computer science. For our research, we firstly identify the challenges actors are facing in motion capture, as well as suggest possible concepts to support the actors. Thereafter, we explore initial prototypes built to support actors during their performance in a motion capture studio. The resulting insights from these initial prototypes led to the design exploration and development of a mixed reality head-mounted projection display that allows showing virtual scenery to the actors and provides real-time acting support. Thereafter, we describe our developed mixed reality application and our findings on how hardware and software prototypes can be designed as acting support, usable in a motion capture environment. A working prototype allowing to evaluate actors' experiences and performances was built as a proof-of-concept.

Additionally, we explored the possibility to use our developed mixed reality prototype in other fields and investigated its applicability for computer games and as an industrial simulator application.

Finally, we conducted user studies with traditionally trained theatre and TV actors, experienced motion capture actors and experts, evaluating the experiences with our prototype. The results of these user studies indicate that our application makes it easier for motion capture actors to get into demanded moods and to understand the acting scenario. Furthermore, we show a prototype that complies with the requirements of a motion capture environment, that has the potential to improve motion capture acting results and supports actors with their performances.
