Development of Human Interface Devices for Psychological Research

Abstract

Following by the recent development of enhanced cameras, the technology of human sensing has become more advanced to automatically extract useful information from camera images. In psychological research, this technology will enable automation of behavior analysis during conversation, eye-tracking from ordinary cameras, and enhancement on the testing procedure based on eye movement characteristics for eidetic imagery studies. Here, we demonstrated an omnidirectional camera to analyze behaviors（utterances,  facial expressions, head-nod, and -posture） of participants in a conversation, a gaze-keyboard to demonstrate eye-tracking using a built-in laptop camera, and a customized software and hardware system for eidetic imagery tests.
