Resource-Based Models of Visual Interaction: Understanding Errors
VLHCC '05: Proceedings of the 2005 IEEE Symposium on Visual Languages and Human-Centric ComputingPages 137–144https://doi.org/10.1109/VLHCC.2005.55We propose a resource-based model of human-computer interaction, and discuss how WIP-POG, a rule-based language for multiset transformations, can support such a model. WIPPOG is here adopted as an enactment mechanism for task models expressed by a visual ...
