ACT-Droid is a tool for directly connecting ACT-R with Android applications on smartphones or tablets. The advantage of this tool is that no prototyping of the application is needed. This tool is especially useful to evaluate applications according to usability by using general modeling approaches.ACT-R model: "Modeling of Visual Search and Influence of Item Similarity"
Lindner, Stefan ; Rußwinkel, Nele ; Ahrlt, Lennart ; Neufeld, Max ; Schattenhofer, Lukas (2017-05-31)
A modeling approach addressing visual search in an array of items of differing similarity is introduced. The model is able to capture the effects found in a study that varies target-distractor similarity (low vs. high), distractor-distractor similarity (low vs. high) of icons, target presence (present vs. absent) and the set size (8, 16 or 24 icons). To be able to simulate human visual search i...Towards a General Model of Repeated App Usage
Prezenski, Sabine ; Russwinkel, Nele (2016)
The main challenge of implementing cognitive models for usability testing lies in reducing the modeling effort, while including all relevant cognitive mechanisms, such as learning and relearning, in the model. In this paper we introduce a general cognitive modeling approach with ACT-R for hierarchical, list-based smartphone apps. These apps support the task of selecting a target, via navigating...
