An ePartner is a personal computer application that helps its user to achieve personal goals such as managing his or her health related behaviors concerning nutrition, exercise and medication. The aim of the first phase of the ‘ePartners that Care’ project is to achieve a general method and framework for the incremental development of such ePartners. The method of situated Cognitive Engineering (sCE), focusing on the functional specifications, has been used as starting point. As a complement, this report aims at establishing well-structured, substantiated and reusable design specifications of the shape (“look and feel”) of the user-ePartner interaction. ---- First, we identified basic characteristics of the user-ePartner dialogue and derived a first set of general interaction requirements from these characteristics. For example, requirements were specified for the adaptive response to cognitive, social and affective processes, the adaptive dialogue style, the choice of modalities and the initiative in the interaction. ---- Second, we tailored and worked out an interaction design pattern technique that complements the functional or task-level design specification of the sCE-methodology. Specifications of interaction design have the advantage that they provide (a) a common and well-structured format for reusable specifications of best practices, (b) a common vocabulary for ePartner development in multidisciplinairy teams, and (c) clear components for validation of interaction design solutions. ---- Third, we generated an example pattern specification for different types of Praise with their interrelationships and dependencies on user and context characteristics. It is a concise and coherent specification that can be easily applied and tested in future prototypes. More general, the method of situated Cognitive Engineering (sCE) has been improved and extended to generate and test interaction shapes in a structured way, aiming at concise and coherent specifications that can be easily shared, refined and re-used. ---- In the next phase, we will continue to build an interaction design pattern library that is explicitly tailored to ePartner functions. The development of this library will entail both the creation of new patterns and the incorporation of patterns from other sources via pattern mining. In current and future ePartner applications, different patterns will be instantiated and further tested. sCET will be further improved to facilitate this process of generation, refinement, validation, structuring and re-use of interaction design patterns.
