This research aims to leverage digital drawing as a non-verbal language to transcend the communication barriers faced by individuals with partial to complete locked-in syndrome (LIS). It will explore the possibility of using the human body as an interface, through assistive technology, in accordance with its limitation in functionality, to facilitate social reconnection and emotional expression through drawing. This approach is grounded in the understanding that creative expression and communication are fundamental human needs and can significantly impact the well-being and quality of life of individuals with severe motor impairments. This paper will focus on the development of the drawing activities. These activities will run under a mixed reality set that can be tailored by caregivers or therapists to the end-user's needs and preferences, ensuring functionality and user satisfaction through an accessible, enriching, and emotionally rewarding experience.
