무대극 공연을 위한 다면 영상 솔루션 콘셉트 디자인 연구 = Study on Multi-display Solution Concept Design for Stage Performance

다국어 초록 (Multilingual Abstract)

(Background and Purpose)In the field of stage performance, using projection mapping makes it possible to express conversion of space-time seamlessly and allows audience to be immersed in the story of a play more deeply. Recently more complex screen and interaction based visual effects have been increasingly required in that field. But technical barriers, system complexity and constraints of the theater environment are becoming obstacles that make it difficult to try ever new attempts or expressions using entire space of a stage. So this study deals with contextual research for understanding latent needs, environmental specialties and inefficiency factors in terms of working level to build design directions. And we defined new multi-display solution concept and the composition of interface based on the directions. (Method)Especially we have used an iterative design process based on repetitive prototyping and pilot performance to find subtle issues and understand competing claims in the live performance. Therefore we had taken part in stage performance making process using our prototype program as system operator and interviewed the working level experts. Through the steps, we defined the design directions and the design concepts of system and interface. (Results)Through the field centered research, we built following 5 design directions. (1)Support for the methods to filter problems related to visual effects out in the planning stage in advance. (2)Support for challenging and experimental video production method. (3)Support for rapid projection mapping and calibration techniques optimized on the theater environment. (4)Support for intuitive control interface to operate the system stably. (5)Support for trouble handling methods for prompt response during live performance. It means it should be able to support new and experimental attempts and consider the seamless performance operation simultaneously. (Conclusions)For that, this research suggests some concepts for the new multi-display control program including following functions. (1)In the planning step, stage 3d simulator will help user to imagine look of the stage easily and find unsuspected conflicts related to lights, stage sets, video and visual devices without building real stage. (2)In the step of building stage, automatic screen extractor, manual screen editor and remote-monitoring are included to raise work efficiency for the projection mapping and calibration. (3)In the rehearsal step, through the partial edit concept for video mapping witch has area cropping and warping function, we try to secure high degree of freedom on instant change and raise resource recyclability. (4)In the system operating step, refinement of control interface and duplex system will make it raise stability during live performance. And we include interactive visual control concept to make synchronization to be more natural between movie and actor. (5)In the post processing step, it will offer the operation information report including working list, error report, device resource usage and operator‘s message based on timeline. Through these functions, we suggest new multi-display solution considering the distinct characteristics of the live performance field and high quality multi-projection mapping.
