The user-resource-task model in intelligent interaction space

The essence of intelligent interaction space is that humans employ resources to complete tasks. This paper firstly established the three element models of intelligent space, and put forward two key obstacles to the development of interaction technology, including the cognitive gap between tasks and resources, and the cognitive burden between users and resources. Then task analysis and ability matching method were proposed to solve the cognitive gap, and model inversion method was presented to deal with cognitive burden, whose usability was certified by demonstration experiments.
