Estimating Cognitive Performance Changes Based on Psychophysiological Sensor in the Smartphone: A Proposed Model

In the last few years, the approach to introducing cognitive performance automatically gained significant scientific interest. Likewise, cognitive performance observation research using the method of collecting the results of objective measurements that occur in everyday life. Today almost everyone has a smartphone, and they have become partners in living their daily lives. The smartphone has been equipped with various kinds of sensors to facilitate its use and for its full features. The existence of sensors on a smartphone is also the potential to be used to obtain information and the user’s situation for a long time and does not disturb the user. Therefore, research using smartphone sensing provides research opportunities in the field of psychology, especially for observing the cognitive performance of users. This study aimed to investigate the possibility of using smartphones as a medium to detect cognitive performance in general outside laboratory conditions.
