  The increasing prevalence of Autism Spectrum Disorder and Attention-Deficit/
Hyperactivity Disorder among students highlights the need to improve evaluation
and diagnostic techniques, as well as effective tools to mitigate the negative
consequences associated with these disorders. With the widespread use of
touchscreen mobile devices, there is an opportunity to gather comprehensive
data beyond visual cues. These devices enable the collection and visualization
of information on velocity profiles and the time taken to complete drawing and
handwriting tasks. These data can be leveraged to develop new
neuropsychological tests based on the velocity profile that assists in
distinguishing between challenging cases of ASD and ADHD that are difficult to
differentiate in clinical practice. In this paper, we present a proof of
concept that compares and combines the results obtained from standardized tasks
in the NEPSY-II assessment with a proposed observational scale based on the
visual analysis of the velocity profile collected using digital tablets.
