Abstract. Implementation of adequate conversational structures is a key issue in developing successful interactive user interfaces. A way of testing the adequacy of the structures is to prove the correct orientation of each communicative action towards a preceding action. We refer to this orientation leading to a certain response as the affordance of the communicative action. In this paper we present a case study where affordances of implemented conversational structures (including verbal and graphical elements) in a multimodal medical QA system are identified applying Conversation Analysis (CA) tools and tested using the Cognitive Walkthrough (CW) method. The CW method was modified to fit the conversational approach and tested with five expert evaluators. Results showed that the affordance analysis helps detecting inefficient constructions leading to disruptions in the dialog flow, spots unnecessary functions and provides important insights on systems easy-of-use.

“…Much work has been done to integrate synthetic personae into electronic display systems, notably in entertainment, CAE and e-retail contexts (see Dehn and van Mulken, 2000 for an overview). Cassell et al (2000) describe Rea, a conversational synthetic persona which will accept speech input from users and generate task oriented dialogues mediated by detecting conversational cues (via video input) from the user. Rea has been demonstrated acting as a real estate sales advisor.…”

This paper reports on and discusses recent research into software agent mediated retailing and considers how it may act as a catalyst to the formation of local electronic retail communities. Each member of the e-retail community has their own software agent that acts on their behalf. Their software agent acts as an electronic Personal Sales Assistant (ePSA), interacting with the person and assisting with the selection and purchase of products. We consider issues that arise when each person can express their likes and dislikes for various aspects of the product range to their software agent, both in terms of the software agent's ability to serve them better, and how such preferences may be shared with others in the larger community to help them -and others in the community -make better and more informed choices. The investigations reported use the MAPPA system, an experimental kiosk based e-retail system. MAPPA integrates a software agent based architecture, a novel form of product display and the use of an animated character agent to enhance the user's sense of personalisation. We report on user evaluation studies of the MAPPA system to investigate the effectiveness of the character agent as an interface to the e-retail system using both conventional usability evaluation techniques and eye-tracking technology. We also describe a simulation program that allows us to investigate the dynamics of e-retail community cohesion when a number of different parameters are considered, including the characteristics of the individual community members and the algorithms employed by the software agents to share information. Lastly, we develop and discuss notions of loyalty, trust, reputation and preference, four issues critical to the development and maintenance of the relationships between individual people, their personal software agents, businesses and the larger e-retail connected community. We propose these issues as "supra-functional" criteria for human-computer interaction design in this area.

Abstract. Cognitive appraisal theories, which link human emotional experience to their interpretations of events happening in the environment, are leading approaches to model emotions. In this paper, we investigate the computational modeling of appraisal in a multi-agent decisiontheoretic framework using POMDP based agents. We illustrate how five key appraisal dimensions (motivational relevance, motivation congruence, accountability, control and novelty) can be derived from the processes and information required for the agent's decision-making and belief maintenance. Through this illustration, we not only provide a solution for computationally modeling emotion in POMDP based agents, but also demonstrate the tight relationship between emotion and cognition. Our model of appraisal is applied to three different scenarios to illustrate its usage. We also discuss how the modeling of theory of mind (recursive beliefs about self and others) is critical for simulating social emotions.
