There are millions of people worldwide who are unable to reliably use natural speech for daily communication who come to use augmentative and alternative communication (AAC). AAC can take multiple forms, including high-tech AAC systems that make use of computer-based technology, such as mobile phones and tablets. There are multiple design options for high-tech AAC, with one option being grid-based displays where items to communicate are laid out in a row-column grid. This work studies how people using grid based AAC systems complete two different types of tasks: requesting and interpersonal. In addition to studying how the tasks are generally completed, this work also studies the impact of grid size and user demographics on how the tasks are completed. This work uses small, medium, and large grid sizes and focuses on participant major as the targeted demographic, with participants majoring in special education or computer science. Participants in this study are asked to complete a series of ten tasks using a grid based AAC system configured with one of the three grid sizes and a post-survey asking for their experience using this system. No statistically significant difference was found when analyzing the task response data by grid size or major but asking participants to tell a joke proved to be a consistent outlier in the analysis. Despite finding no statistical significance between tasks, the analysis of the survey data indicated that participants reported experiencing differences based on the grid size of their system. Common experiences were found when analyzing by major, with both majors indicating the same frustrations of organization and rate of communication.
