Envisioning the (In)Visibility of Discreet andWearable AAC Devices

High-tech augmentative and alternative communication (AAC) devices can offer vital communication support for those with complex communication needs (CCNs). Unfortunately, these devices are rarely adopted. Abandonment has been linked to many factors commonly, stigma resulting from the visibility of the device and its intrusion into other essential modes of communication like body language. However, visible AAC is strategically useful for setting conversational expectations. In this work, we explore how we might envision AAC to address these tensions directly. We conduct user-centred design activities to build three high-fidelity AAC prototypes with different communities with CCNs, specialists and stakeholders. The prototypes demonstrate different form factors, visibility and modes of input/output. Subsequently, we conduct two qualitative focus groups using convergent and divergent co-design methods with people with the language impairment aphasia - supporting ideation of seven discreet and wearable low-fidelity AAC prototypes and critique of the three high-fidelity prototypes.
