Designing for disability is a very specialised area as it requires interdisciplinary expertise, and designing assistive devices for children with communication disorder, is especially a challenge as these users are incapable of providing adequate and coherent feedback. With the adoption of participatory design approach, in collaboration with experts/professionals/educators, as pivotal stakeholders and a proxy for the end-users; a game-based, multi-sensory learning aid has been developed to train children on the concept of sense organs. Several concepts were generated and evaluated through special educator participation and based on a preliminary survey of external special educators as evaluators, the prototype was found to be suitable for the target user to enhance their communication skills. This paper captures a research through design perspective on the design of customisable solutions for beneficiary user groups, who are unable to offer feedback.
