SentiGaze technology capabilities
SentiGaze is a proprietary gaze tracking technology which is designed to be used on a common PC with a common camera. The possible applications of the gaze tracking technology include:
- Heat map based reasearch and analytics for single and multiple subjects:
- usability of websites and applications.
- film screening.
- advertising research for both TV and static ads (posters, product placement etc).
- Device and application control:
- full or auxiliary control of an application or device.
- working with multiple screens.
- video games.
- accessibility for disabled people.
- Medical and scientific research.
SentiGaze technology has these capabilities for gaze tracking and session recording:
- Simple usage: SentiGaze technology is designed to work with regular webcams and requires no specific hardware like specialized gaze-tracking cameras or fixing person's head in a rigid position. Proprietary algorithms are used to detect subjects's eyes on the captured video track movement. No physical contact required at any stage of gaze tracking.
- Adaptive to screen size and distance from screen: A simple short procedure calibrates SentiGaze fro specific environment before gaze tracking session. Users are guided to fix their gaze at several points on the screen during the calibration procedure.
- Real-time gaze tracking: SentiGaze tracks user's gaze and provides results in real time. The gaze tracking session can be also saved for future use.
- Heat map generation: Gaze tracking session can be represented as a heat map which can be generated an top of screen contents like web pages, applications, static images or videos. Live preview of the heat maps is available. SentiGaze generates heat maps for single subjects and can also summarize individual heat maps for multiple subjects gaze statistics.
- Application control: SentiGaze funtionality can be used for enabling computer, device or application control using gaze as a pointer. The possible applications may range from gaze-controlled software to additional input method for computer games.
- Accessibility: Specialized software for disabled people can be developed to provide gaze-based control where other accessibility options are not suitable.
- Compatible with other Neurotechnology products: SentiGaze can be used with other Neurotechnology products for applications which require additional biometric data.
Recommendations and Specifications
- Camera should be placed under the screen. Laptop build-in cameras are not suitable due to their fixed placement, thus a separate external webcam is recommended.
- User should be positioned at 45-80 cm (1'6"-4'0") from the screen. 60 cm (3'0") is the optimal distance from the screen for convenient gaze tracking.
- Screen sizes up to 24" (61 cm) are supported by SentiGaze.
- Calibration should be performed before a user will start working with SentGaze based application at particular computer and camera. The calibration process is simple and convenient, as it guides the user to gaze at specific points on the screen. Three calibration modes with 9, 12 and 16 points are available; more points increase the accuracy of gaze tracking.
- Binocular eye data is used for gaze tracking.
- Tracking performance is more than 30 frames per second on a PC with Intel Core i7-3770 processor running at 3.4 GHz clock rate.
