The tool of choice in human factors automotive research worldwide, faceLAB® v4 builds on its reputation as an all weather, all condition human performance measurement system. This new tracker introduces Precision Gaze mode, for those simulation installations where fidelity of feedback is everything.

With its simple and reusable calibration process, faceLAB® gets your team on the road and collecting data quickly. Its unique 3D world model system enables automatic data collation, for gathering data on interaction with physical objects inside the vehicle. Useful for in-vehicle telematics experiments, driver behaviour analysis or the evaluation of cognitive workload, fatigue or distraction levels of drivers of all vehicles.

faceLAB® produces accurate data on-time, in the toughest of tracking environments. From outdoor intelligent vehicle or aerospace studies through to screen & web usability, stimulus response and laboratory environments, faceLAB® provides high accuracy and tolerance to a wide range of operational conditions.

When combined with world model items, faceLAB clearly shows the gaze intersection with specific items within the environment in real time.

New in faceLAB® v4 is a leading-edge active illumination technique, increasing the fidelity and accuracy of gaze assessment. Track each eye independently, and if the subject is close enough, even track pupil size and vergence. If conditions degrade, faceLAB® continues to maintain the confidence of its classic, robust tracking system by default. Analyse and model fatigue and drowsiness in real-time with faceLAB®'s true blink analysis and PERCLOS fatigue assessment, including data on the minutia of eyelid behavior. Measurements are taken accurately on eyelid position rather than bright pupil or corneal occlusion.

Eliminate the hassle of interference, setup and correlation issues associated with traditional contact-based tracking methods—faceLAB® does not use any RF, ultrasonic or electromagnetic systems. Our unique visual tracking system provides a single stream of data. No need to stitch or align multiple tracking devices to obtain a result. No painstaking calibration of separate head tracking systems—faceLAB® itself caters to changes in pose or the movement of a subject. Specific techniques have been implemented in faceLAB® v4 to enable easier calibration of children and uncooperative subjects.

Minimise the time, cost and headache associated with experiments with faceLAB®'s unparalleled ease of use, quality of support and user-friendly interface. faceLAB®'s hallmark automatic initialisation feature has been improved, and now produces raw gaze output automatically, as well as head position and blink events over a wider field of view. Laboratory or simulator implementations are further enhanced—a wide variety of digital simulation platforms and third-party analysis tools are now natively supported. Get direct representation of subject interaction inside your simulation environment, in real-time, and synchronised correctly to the experiment. Don't restrict your eye tracking experiments to screens—faceLAB® continues to offer a fully integrated 3D world model that encompasses physical objects as well as displays.

The Video Overlay Kit (VOK) option for faceLAB allows real-time overlay of head-pose and eye gaze data with the subject's actual viewing patterns of live video.

Maintain data and tracking integrity through a range of lighting and movement conditions. faceLAB® immediately recovers if a subject leaves the field of view, and the system is robust to occlusion or sudden movement. Work with all faces and all eye types, with or without contact lenses and with most eye-glasses. Work in bright sunlight or at night time, with subjects close to the camera or several metres away. Even if you can't see the eyes—if the subject is wearing sunglasses for instance—faceLAB® still finds the head pose, eyes and mouth, and continues to produce accurate, robust and reliable data. Added flexibility is provided with the new ultra-wide field of view mode, allowing experiments with distant subjects or a variable experimental area. Reduce the amount of data stored or transmitted with variable width logging—capture only the data you need, and send it across a network where you need it.

Develop real-time applications using the faceLAB® freely available SDK, enabling other systems to localise salient facial features such as the eyes and mouth, in real-time, across standard network interfaces.

Seeing Machines has simplified the path to commercialising products based on faceLAB® technology with a licensable core now available.

Advantages

• gaze data, head position and blink information;
• outdoor or indoor, day and night operation;
• PERCLOS analysis at 60Hz, as well as raw eyelid position estimation for creation of new metrics or visible fatigue models;
• robust operation, tolerant to extremes of lighting conditions including sunlight;
• ability to tolerate rapid or sudden movement of drivers—naturalistic behavior is OK;
• ultra wide field of view head mode if head tracking only is required;
• real-time as well as smoothed (accurate) data transmitted across common network interfaces;
• flexible file format—choose what data you want to transmit or store;
• time-synchronisation possible across multiple devices utilising a standard NTP synch protocol;
