Gazepoint Biometrics

Gazepoint Biometrics

Gazepoint Biometrics is a research-grade hardware kit designed to record physiological signals and participant self-reported engagement. The system measures heart rate and galvanic skin response (GSR), also known as EDA (Electrodermal Activity), and an additional dial allows the participant to provide an analog engagement score ranging from 0% to 100%.

The kit can operate standalone, without an eye tracker, or be paired with a Gazepoint GP3 ​​60 Hz or GP3 HD 150 Hz device. In this combined configuration, biometric data can be recorded and synchronized with gaze direction data and—in the case of an eye tracker—pupil size.

The Hardware Only version is primarily intended for researchers and developers who wish to use their own software or the included API/SDK. The eye tracker and the full Gazepoint Analysis UX license are not included.

Software Required for Operation

Gazepoint Control

Gazepoint Control is the basic component that handles communication with the hardware. The manufacturer describes how to start the system by:
connecting the finger sensor to the module with the dial,
connecting the module to the computer's USB port,
enabling the Biometrics function in Gazepoint Control.

The program acts as a server, sharing biometric data with the Gazepoint Analysis application or with your own software using the API.

OpenGaze API and SDK

The API and SDK are included with the purchase of the Hardware Only version. They enable you to create your own applications for:
initiating registration,
receiving biometric data in real time,
synchronizing data with eye tracking,
adding your own event markers,
saving data in your own research system,
and further processing the data in Python, MATLAB, or another environment.

Communication takes place via a TCP/IP connection to the Gazepoint Control server.

Gazepoint Analysis UX Edition – optional, additional fee

Gazepoint Analysis UX Edition is required if the user wants to use a ready-made interface for visualizing biometric data without developing their own application.
The software offers, among other things:
biometric data visualization,
synchronization of biometric data with eye tracking,
heat maps,
fixation paths,
screen image capture,
support for images, videos, and websites,
dynamic AOIs (Areas of Interest),
participant voice recording,
webcam image recording,
export of data and test results.

The "Biometrics Data Visual Display" feature requires the Gazepoint Biometrics bundle. Gazepoint Analysis UX is not listed as part of the current Hardware Only bundle and requires a separate license.

Eye tracker – optional

Gazepoint Biometrics does not require an eye tracker to record heart rate, GSR, and self-assessment of engagement. The GP3 or GP3 HD eye tracker is only needed if the test also includes:
gaze point,
fixations,
eye movement,
pupil diameter,
and
associating a physiological response with a specific element of the viewed material.

The manufacturer confirms that the system can operate independently and integrate with GP3 and GP3 HD devices.
