Abstract:
Response of the autonomic nervous system can be assessed by quantifying the
dilation of the pupil of a human placed under suitable luminous conditions. When the
intensity of the surrounding light is low, human’s pupil dilates to capture a maximum
number of photons. At the same time dilation is affected by Human Autonomic nervous
System response. The aim of this paper is to assess the effects of stress on pupil through
Autonomic Nervous System that an Individual experiences, with a view to apply it in a
practical manner for detecting a lie during the course of interrogation. The paper presents
two point algorithm devised specifically for pupil detection under Infrared rays at higher
speed as compared to present day Algorithm and suggest research methodology for
future.
