Cog-Pack(trade mark) Eye/Head/Gaze/Heatmap/3D Display Documentation
Abstract
Viewing physiological signals can take many forms. Historically, electro-mechanical devices contained the elements required to display the waveforms. These devices used mechanically driven rolls of paper tape with pens to transcribe the waveforms of interest over time. A modern example that may be familiar to many is the polygraph machine. A polygraph machine typically displays blood pressure, pulse rate, respiration, and skin conductivity to the examiner. From these waveforms, the examiner then determines the validity of a test subject's statements. Given the new emphasis on digital technologies and the rise of software-based solutions, many physiological devices still present the waveform data to a user as a strip-chart. These strip-charts are useful for many physiological data types, but not all. In some circumstances, three dimensional (3D) models may provide greater insight. For Eye, Head, and Gaze-based data-types, as well as a few additional derived types, creating and displaying a 3D world model may afford a more comprehensive view of a participant's interaction with task elements. Additionally, when presenting data in real-time from more open-ended experimental design constructs, further consideration in the presentation of these data can be constructed. This document discusses the approach taken in COG Pack to not only display those data-types but permits many additional controls and adjustments.
