1st International Workshop on Pervasive Eye Tracking and Mobile Eye-Based Interaction

During the UbiComp 2011 in Beijing in September the 1st International Workshop on Pervasive Eye Tracking and Mobile Eye-Based Interaction (PETMEI) will be held. Keynote speaker is Jeff B. Pelz who has considerable experience with eye tracking during natural tasks. The call for paper is out, see details below.
"Recent developments in mobile eye tracking equipment and automated eye movement analysis point the way toward unobtrusive eye-based human-computer interfaces that are pervasively usable in everyday life. We call this new paradigm pervasive eye tracking – continuous eye monitoring and analysis 24/7. The potential applications for the ability to track and analyze eye movements anywhere and anytime call for new research to further develop and understand visual behaviour and eye-based interaction in daily life settings. PETMEI 2011 will focus on pervasive eye tracking as a trailblazer for mobile eye-based interaction and eye-based context-awareness. We provide a forum for researchers from human-computer interaction, context-aware computing, and eye tracking to discuss techniques and applications that go beyond classical eye tracking and stationary eye-based interaction. We want to stimulate and explore the creativity of these communities with respect to the implications, key research challenges, and new applications for pervasive eye tracking in ubiquitous computing. The long-term goal is to create a strong interdisciplinary research community linking these fields together and to establish the workshop as the premier forum for research on pervasive eye tracking."

Specs for SMI GazeWear released

The specifications for the SMI GazeWear has just been announced. The head mounted tracker takes the shape of a pair of glasses and has a impressive set of features. It offers 30Hz binocular tracking (both eyes) at 0.5 deg accuracy with automatic parallax compensation for accurate gaze estimation over distances above 40cm. The dark pupil, corneal reflection based system has a tracking range of 70° horizontal / 55°. vertical angle. SMI has managed to squeeze in a HD scene camera located in the center of the frame which offers 1280x960 resolution at 30 frames per second. However, the viewing angle is slightly smaller than the tracking range at 63° horizontal and 41° vertical angle. The weight of the device is specified to 75 grams with the dimensions of 173x58x168mm (w/h/d) and is estimated to fit subjects above age 7.

SMI GazeWear
A mobile recording unit is offered which stores data on a SD card, weighs 420 grams, and has minimum of 40 minutes recording time. However, a subnotebook can be used to extend recording time towards two hours.   

With the new tracker SMI seriously improves their offering in the head mounted segment with a form factor that certainly appears more attractive to a wide range of applications. The specs stands up well against the Tobii glasses which has a similar form but is limited to monocular tracking and a lower resolution scene camera.  No details on availability is provided other than "coming soon", something we heard since late December. Once they are out the game is on. 

The flyer may be downloaded as pdf.

Development of a head-mounted, eye-tracking system for dogs (Williams et al, 2011)

Fiona Williams, Daniel Milss and Kun Guo at the University of Lincoln have developed a head mounted eye tracking system for our four legged friends. Using a special construct based on a head strap and a muzzle the device was mounted on the head of the dog where a dichroic mirror placed in front of one of the eyes reflects the IR image back to the camera.


The device was adapted from a VisionTrack system by IScan/Polhemus and contains two miniature cameras, one for the eye and one for the scene which is connected to a host workstation. When used with human subject such setup provides 0.3 deg. of accuracy according to the manufacturer. Williams et al obtained an accuracy of 2-3 deg. from a single dog when using a special calibration method containing five points located on a cross which was mounted at the tip of the muzzle. Using positive reenforcement the dog was gradually trained to wear and fixate targets which I'm sure wasn't an easy task.


Abstract:
Growing interest in canine cognition and visual perception has promoted research into the allocation of visual attention during free-viewing tasks in the dog. The techniques currently available to study this (i.e. preferential looking) have, however, lacked spatial accuracy, permitting only gross judgements of the location of the dog’s point of gaze and are limited to a laboratory setting. Here we describe a mobile, head-mounted, video-based, eye-tracking system and a procedure for achieving standardised calibration allowing an output with accuracy of 2–3◦. The setup allows free movement of dogs; in addition the procedure does not involve extensive training skills, and is completely non-invasive. This apparatus has the potential to allow the study of gaze patterns in a variety of research applications and could enhance the study of areas such as canine vision, cognition and social interactions.

Fraunhofer CMOS-OLED Headmounted display with integrated eye tracker

"The Fraunhofer IPMS works on the integration of sensors and microdisplays on CMOS backplane for several years now. For example the researchers have developed a bidirectional microdisplay, which could be used in Head-Mounted Displays (HMD) for gaze triggered augmented-reality (AR) aplications. The chips contain both an active OLED matrix and therein integrated photodetectors. The combination of both matrixes in one chip is an essential possibility for system integrators to design smaller, lightweight and portable systems with both functionalities." (Press release)
"Rigo Herold, PhD student at Fraunhofer IPMS and participant of the development team, declares: This unique device enables the design of a new generation of small AR-HMDs with advanced functionality. The OLED microdisplay based Eyetracking HMD enables the user on the one hand to overlay the view of the real world with virtual contents, for example to watch videos at jog. And on the other hand the user can select the next video triggered only by his gaze without using his hands." (Press release)

Sensor integrates both OLED display and CMOS imaging sensor. 

Rigo Herold will present the system at the SID 2011 exhibitor forum at May 17, 2011 4:00 p.m.: Eyecatcher: The Bi-Directional OLED Microdisplay with the following specs:
  • Monochrome 
  • Special Eyetracking-Algorithm for HMDs based on bidirectional microdisplays
  • Front brightness: > 1500 cd/m²

Poster was presented at ISSCC 2011 : Industry Demonstration Session (IDS). Click to enlarge

In addition there is a paper titled "Bidirectional OLED microdisplay: Combining display and image sensor functionality into a monolithic CMOS chip" published with the following abstract:. 

"Microdisplays based on organic light-emitting diodes (OLEDs) achieve high optical performance with excellent contrast ratio and large dynamic range at low power consumption. The direct light emission from the OLED enables small devices without additional backlight, making them suitable for mobile near-to-eye (NTE) applications such as viewfinders or head-mounted displays (HMD). In these applications the microdisplay acts typically as a purely unidirectional output device [1–3]. With the integration of an additional image sensor, the functionality of the microdisplay can be extended to a bidirectional optical input/output device. The major aim is the implementation of eye-tracking capabilities in see-through HMD applications to achieve gaze-based human-display-interaction." Available at IEEE Xplore.

AutomotiveUI'11 - 3rd International Conference On Automotive User Interfaces and Interactive Vehicular Applications

"In-car interactive technology is becoming ubiquitous and cars are increasingly connected to the outside world. Drivers and passengers use this technology because it provides valuable services. Some technology, such as collision warning systems, assists drivers in performing their primary in-vehicle task (driving). Other technology provides information on myriad subjects or offers entertainment to the driver and passengers.

The challenge that arises from the proliferation of in-car devices is that they may distract drivers from the primary task of driving, with possibly disastrous results. Thus, one of the major goals of this conference is to explore ways in which in-car user interfaces can be designed so as to lessen driver distraction while still enabling valuable services. This is challenging, especially given that the design of in-car devices, which was historically the responsibility of car manufacturers and their parts suppliers, is now a responsibility shared among a large and ever-changing group of parties. These parties include car OEMs, Tier 1 and Tier 2 suppliers of factory-installed electronics, as well as the manufacturers of hardware and software that is brought into the car, for example on personal navigation devices, smartphones, and tablets.

As we consider driving safety, our focus in designing in-car user interfaces should not be purely on eliminating distractions. In-car user interfaces also offer the opportunity to improve the driver¹s performance, for example by increasing her awareness of upcoming hazards. They can also enhance the experience of all kinds of passengers in the car. To this end, a further goal of AutomotiveUI 2011 is the exploration of in-car interfaces that address the varying needs of different types of users (including disabled drivers, elderly drivers or passengers, and the users of rear-seat entertainment systems). Overall our goal is to advance the state of the art in vehicular user experiences, in order to make cars both safer and more enjoyable places to spend time." http://www.auto-ui.org


Topics include, but are not limited to:
* new concepts for in-car user interfaces
* multimodal in-car user interfaces
* in-car speech and audio user interfaces
* text input and output while driving
* multimedia interfaces for in-car entertainment
