Employing use-cases for piecewise evaluation of requirements and claims.
ABSTRACT Motivation -- Complex design specifications must be partitioned in manageable pieces to be able to evaluate them in separate experiments. No methodology existed to deal with this task. Research approach -- Practical experience in Situated Cognitive Engineering and the Mission Execution Crew Assistant is combined with a theoretical perspective on the relation between use-cases, requirements and claims. Findings/design -- Hierarchical clustering is an effective method for partitioning a design specification. Use-cases provide a good criterion based on which to cluster the requirements and claims. Originality/Value -- A new method and tool are presented for organising requirements and for systematising the evaluation of a complex design specification. Take away message -- Piecewise evaluation benefits from a use-case-based partitioning of the design specification combined with an experimental stance on requirements and claims.

ABSTRACT: Social embodied agents may mitigate moments of apathy and confusion that older adults can experience at home. Based on a literature study, use cases, requirements and claims were specified. In an experiment with 29 older adults (aged 70+), it was studied to what extent a virtual agent and three robots (i.e., the Nao, iCat and Nabaztag) provide a platform to support these use cases, requirements and claims. Participants seemed to evaluate the agents mainly in terms of three generic components: the perceived level of realism, intellectuality and friendliness. A more serious and agreeable appearance improved the appreciation of the agent's actions. Especially facial realism appeared to be important for trust, social presence, perceived sociability and perceived enjoyment.Social Robotics - Third International Conference, ICSR 2011, Amsterdam, The Netherlands, November 24-25, 2011.
