Having a virtual talking face along with a virtual body increases immersion in VR applications. As virtual reality (VR) techniques develop, various applications are increasing including multi-user social networking and education applications that involve talking avatars. Due to a lack of sensory information for full face and body motion capture in consumer-grade VR, most VR applications do not show a synced talking face and body. We propose a novel method, targeted for VR applications, for talking face synced with audio with an upper-body inverse kinematics. Our system presents a mirrored avatar of a user himself in single-user applications. We implement the mirroring in a single user environment and by visualizing a synced conversational partner in multi-user environment. We found that a realistic talking face avatar is more influential than an un-synced talking avatar or an invisible avatar.

The purpose of this paper is to examine the problems caused by the lack of institutional establishment of broadcasting contents' concept, to present the categories and significance of broadcast contents concepts, and to promote discussions on defining broadcasting contents concepts. As the pattern of enjoying contents becomes fragmented, broadcasting contents such as dramas, entertainment, and documentaries are enjoyed in various ways through N-screens, beyond the distribution structure of the traditional broadcasting industry. But, the concept of broadcasting contents is subordinate to(or even absent from) the distribution structure of the broadcasting industry. This paper seeks to correct this problem by proposing a new definition of broadcasting contents. First of all, as a result of looking at the need to define the concept of broadcasting contents in various ways in principle, legal, and industrial aspects, broadcasting contents needed to be defined as a new concept independent of broadcasting media. Based on this, the existing discussions on the concept and type of broadcasting contents were reviewed to confirm the direction for establishing broadcasting contents concepts, and to define broadcasting contents into higher categories (liberal arts, entertainment), and lower categories ('documentaries, current affairs, education', 'dramas, animation, music, variety, sports').

The purpose of this study was to present a educational content developed for training of dental extraction skill in a virtual environment. The development of the content consists of five steps: learning content analysis, draw a design model, development, test of validity, rectification and complete of the content. We developed the virtual reality (VR) simulator with producing an animation of surgical stages on the 3D models of human face for simulating dental extraction procedure. The results of validity tests for the content were mean 4.81 (SD, 0.72) for interface validity and mean 4.66 (SD, 0.71) for content validity, which represents strong evidence for the validity of the content. The data of the study indicates that the educational content developed for training of dental extraction skill using VR technology can be suitable to improve surgical skill of dental extraction in clinical field. We expect that further development of the education contents based on the VR technology to improve various surgical skills in clinical field will be addressed in the future.
