Previous work on characterising the variety of interaction devices has focused either on physical properties of the devices or the range of behaviours that they can invoke. This work sets out a new approach to evaluating the usability of devices, one that accounts for the cognitive resources needed to use the device to perform particular tasks. The framework draws its expressive power from a technique called syndetic modelling that allows the description of both the device and cognitive resources to be captured in a common representation. In this paper syndesis provides a foundation for examining the coordinate spaces and transformations that are needed both by the operator and the computer system in performing tasks with a given device.
