Communication for people with motor impairments is a difficult, yet necessary, task in daily activities. To do so, soft keyboards, digital counterpart of physical keyboards, are used. Depending on their features, several designs can be considered, however their thoughtful evaluation in real-life is not feasible. Therefore, it becomes necessary to filter the possible configurations wisely, taking advantage of simulation tools. This paper presents STAACS3, a Simulation Tool for AAC with Single-Switch scanning, that allows to model and simulate the performance of any type of scanning keyboard regardless of its keys configuration, scanning strategy or prediction systems.
