A First Step towards a Generalized Physiological Measurement Framework

Abstract

Physiological measures are often used to infer the cognitive state of a user in a training or experimental environment. The use of multiple devices can provide increased insight to the user's state. Two key issues when using multiple sensing devices are the need for low-level knowledge of the sensors for interfacing and software design for reuse. In this paper, an integration of real-time eye tracking and arousal measurement within a simulated environment is presented. The system is a preliminary realization of a general framework for integrating physiological measurement devices with live, virtual, and constructive environments and extends previous work integrating arousal and eye tracking. The data are time-stamped in the context of the simulation and can be “replayed” in the simulation for post-hoc analysis.
