In future video communication services, the user's communication device, such as PC, laptop, PDA or mobile phone is equipped with new interaction modalities. These can be cameras and microphones on the capturing side and speech synthesis and video/3D graphics on the rendering side. Haptic and tactile interfaces become also available. These modalities help the user to interact more intuitive with complex...
The rapid increase in the availability of geospatial data has motivated the effort to seamlessly integrate this information into an information-rich and realistic 3D environment. However, heterogeneous data sources with varying degrees of consistency and accuracy pose a challenge to such efforts. We describe the geospatial decision making (GeoDec) system, which accurately integrates satellite imagery,...
In this paper, we discuss a user interface issue with regard to automatic video editing based on the speaker's intentions. In our experiments, the subjects used previously developed video capturing system to employ 4 types of editing methods by making 3 types of presentations. Subjective evaluation revealed that the editing method that used behaviors-for-attention obtained a good score for a presentation...
We present an interactive workspace that integrates wiki collaboration in knowledge-building activities with face-to-face scenarios like brainstorming or problem solving sessions. A wiki serves as the repository for knowledge elements, which are presented to co-located users in form of a concept map projected on a table. A computer vision module tracks multiple hands and fingers on the table surface...
Interactivity is a key concept in modern content-based retrieval. Therefore, in addition to the ability to learn from user generated data, easy and intuitive to use interfaces are an important area of research in (multi)media retrieval. In this contribution, we focus on the latter aspect and present how different modalities like speech and gestures on super sized touch screen facilities may be integrated...
The informal information can be so intuitive, emotional, personal, honest and subjective that it is very difficult to get them from the formal media. In this paper, we demonstrate a multimedia informal communication support system whose basic architecture is a combination of a wearable computer, a see-through head mounted display, a bone conduction speaker, and a 3D-pen. The user can create a "multimedia"...
Group-to-individual (G2I) distributed meeting is an important but understudied area. Because of the asymmetry between different parties in G2I meetings, it has two unique challenges: l)the remote participant tends to be ignored by the local participants; and 2) the remote participant has inferior audio, video, and data experience than the local participants. To address these issues, in this paper...
We have developed several basic components for our virtualized classroom project: automated data collection, intelligent media integration, and flexible user interfaces. As an example of media integration, we show that when the PPT slides are projected onto the digital whiteboard where the instructor annotates, modifies, or expands the PPT presentation, geometrically registering high-resolution images...
Recently, mobile TV is becoming a mainstream service in mobile broadcasting scenario, where requires lots of mobile factors such as robust transmission, high performance and easy interface and so on. As mobile broadcasting services are being highlighted, the easy interface and appropriate application are increasingly in demand. In most mobile scenarios, where users may actually share their attention...
Recently, the concept of behavioral media using a mobile robot has emerged in tele-robotics, where the mobile robot behaves as a user's second body or an agent in a remote site. An important issue in behavioral media is how to control the robot intuitively immersing a user into a remote site. This paper describes a new approach which combines locomotion interface and immersive projection display of...
