  Screening for any of the Autism Spectrum Disorders is a complicated process
often involving a hybrid of behavioural observations and questionnaire based
tests. Typically carried out in a controlled setting, this process requires
trained clinicians or psychiatrists for such assessments. Riding on the wave of
technical advancement in mobile platforms, several attempts have been made at
incorporating such assessments on mobile and tablet devices. In this paper we
analyse videos generated using one such screening test. This paper reports the
first use of the efficacy of using the observer's distance from the display
screen while administering a sensory sensitivity test as a behavioural marker
for autism for children aged 2-7 years The potential for using a test such as
this in casual home settings is promising.
