Abstract

Our final goal is to utilise a cognition viewpoint for the engineering of a better design of human communication tools. In this paper, we extend the concept of affordance to cover human-to-human communication and propose the novel concept of 'human affordance', which is afforded from humans, not artefacts. As one possible utilisation of the concept, we introduce the example of affordance in evaluating the strength of agreement/disagreement phrases. In text-based communication, it is important for mutual understanding to effectively afford information about how a person feels about the text itself. This paper presents experimental results on over/underestimation in understanding the strength of agreement/disagreement in text-based communication. The human affordance identified in typical agreement/disagreement phrases is analysed in order to explore how to better augment human affordance in text-based communication.
