In: Proceedings of the 2010 International Conference on Multimodal Interfaces 2010. p. 33.
In this paper we propose new quantitative metrics that express the characteristics of current general practices in slide-based presentation methodology. The proposed metrics are numerical expressions of: 'To what extent are the materials being presented in the prepared order?' and 'What is the degree of separation between the displays of the presenter and the audience?'. Through the use of these metrics, it becomes possible to quantitatively evaluate various extended methods designed to improve presentations. We illustrate examples of calculation and visualization for the proposed metrics.

Current user interface techniques such as WIMP or the desktop metaphor do not support real world tasks, because the focus of these user interfaces is only on human-computer interactions, not on human-real world interactions. In this paper, we propose a method of building computer augmented environments using a situation-aware portable device. This device, called NaviCam, has the ability to recognize the user's situation by detecting color-code IDs in real world environments. It displays situation sensitive information by superimposing messages on its video see-through screen. Combination of ID-awareness and portable video-see-through display solves several problems with current ubiquitous computers systems and augmented reality systems.

Takeuchi, Akikazu and Nagao, Katashi (1993): Communicative Facial Displays as a New Conversational Modality. In: Ashlund, Stacey, Mullet, Kevin, Henderson, Austin, Hollnagel, Erik and White, Ted (eds.) Proceedings of the ACM CHI 93 Human Factors in Computing Systems Conference April 24-29, 1993, Amsterdam, The Netherlands. pp. 187-193.
The human face is an independent communication channel that conveys emotional and conversational signals encoded as facial displays. Facial displays can be viewed as communicative signals that help coordinate conversation. We are attempting to introduce facial displays into computer-human interaction as a new modality. This will make the interaction tighter and more efficient while lessening the cognitive load. As the first step, a speech dialogue system was selected to investigate the power of communicative facial displays. We analyzed the conversations between users and the speech dialogue system, to which facial displays had been added. We found that conversation with the system featuring facial displays was more successful than that with a system without facial displays.
