This study investigates the barriers to the effective adoption of gaze-based Augmentative and Alternative Communication (AAC) technology, specifically Google’s free ‘Look to Speak’ app in Ghana. While such technology holds promise for individuals with complex communication difficulties, especially in low resource settings, the research highlights that technology alone is insufficient for successful implementation. The study identifies significant deficits in social, technical, and service infrastructure that impede adoption, potentially outweighing any functional benefits of the technology itself. The research identified critical challenges in the form of a lack of readily available technical support for device maintenance and software updates, coupled with limited access to trained speech and language therapists (SLTs) and caregivers capable of supporting users. The paper emphasises the importance of ‘human infrastructure’, including the availability of informed caregivers and community support, and ‘service infrastructure’, encompassing provision, policy, and personnel within assistive technology services. The research proposes a "technology deficit model" where inadequacies in human and service infrastructure significantly diminish the potential impact of technological innovations.
