At two previous ICDVRAT conferences (2018, 2022) the authors reported on the concept, and then development phase of a tangible toy that could be used to assist in the diagnosis of autism in preschool children. Here, results of the first round of testing on the intended user group are reported. Results show variation between pre-school neurodivergent and neurotypical populations as predicted in terms of speed and accuracy of movement. Fine motor movement can be a potential biomarker for autism that would be less dependent on observational data, and more objective.
