Abstract

Introduction: Computational solutions have great potential to support communication for people with Complex Communication Needs (CCN). However; the high cost and the complexity of these applications remains a barrier to both adoption and the development of novel interaction techniques. Objective: Our main goal was to provide an open-source customizable board software that simplifies the authoring process and mitigates technology abandonment resulting from the complexity of current solutions. Methodology: To define system requirements; we conducted a systematic literature review and workshops with occupational therapists. Results: The resulting solution features functionalities such as intuitive customization of pictographic grids and support for alternative interaction methods; including scanning; ensuring accessibility for users with diverse needs.

Keywords: AAC, CCN, Assistive Technology, Pictographic Board
