The Tobii Gaze SDK version 4.0.3 and the companion .NET SDK version 2.0.3 are now available for download.
The release includes a new tool for calculating the display area and a new calibration sample written in C#/WPF, as well as some bug fixes.
Configuring the active display area just got a whole lot easier for setups where the eye tracker is mounted on a display monitor, or on something that resembles a monitor. The new display area calculator tool is an html page which guides you through the setup process. It is available in the tools directory in the SDK packages.
