IntelliGaze prototype debuts at COGAIN meeting.
The IntelliGazeTM prototype system has been successfully demonstrated at the annual COGAIN meeting in Leicester, UK 3-4 September 2007.
The IG-30 system hardware uses a modular approach enabling gaze interaction on most existing computers. The camera and illumination unit is fully self-contained, connecting to the host computer via a USB2 port.
Using the provided VESA-mount adapter, the camera and illumination unit can be attached to most TFT screens.
The separation of dedicated devices from the standard PC components ensures a longer product lifetime as consumer PC components are usually upgraded every 2-3 years driven by more demanding operating systems, like Windows VISTA. The use of industrial grade camera components ensures the availability of stable drivers for current and future operating systems.
Through the Application Center, the user's desktop can be pre-configured and the application's behavior can be adopted to the users needs. It enables the operator to configure the gaze interaction parameters,i.e. which mouse data will be generated by the framework, whether to support a switching device etc.
After the easy configuration, the application will be available through a gaze activated start button on the Application Center desktop.
The operator might restrict the access to a limited number of applications in order to limit the complexity of the gaze controlled scenario.
The Application Center has been designed as a multi-lingual application. Current options include German and an English modules, and will be extended to all European languages on demand.
Because the system has no adjustable hardware parts, the positioning with respect to the user is the only remaining task before the first gaze calibration can be started.
An easy-to-understand tracking status indicator helps the operator set-up the system. Head-location as well as eye tracking status are accessible to the operator without the need to understand the internal processing at all, while showing enough information to sort out any issues that may arise.
The system needs to be calibrated to the individual subject once after system set-up. The quick interactive calibration is performed by following an animated dot with your eyes and fixating on several locations on the screen. A typical calibration takes less then 30s.
The calibration routine can be adapted to individual requirements by selecting the number of fixation targets, manual or fully automatic operation, target size, etc.. The calibration can also take into account limited vision on a particular eye or strabism.
After the calibration, which already checks for valid data at each point, the user will receive a graphical feedback of the calibration results for both eyes. This allows even the untrained user to estimate the achieved accuracy and whether he should try the automatically-suggested improvement run.
