Release of Gazer Application

We are happy to announce the first public release of Gazer. This is the first broadly available application that allows people to perceive 3D images through dynamic depth of field and eye-tracking technology. This is a new way to show depth in images without requiring a 3D screen. Our technology takes advantage of an eye-tracker (a device that knows where you are looking on the screen) to simulate the focusing process of your eyes’ lens. When you are looking at an object that is close in real life, your eye puts that object in focus, but everything else that is significantly further or closer than the object of interest, appears blurred. Our new application uses this effect to generate a new sensation of depth.

This kind of 3D is particularly suitable for images taken by light-field cameras, such as the Lytro Illum cameras, which have been heralded as the next step in photography.

Our team at the University of St Andrews has been working on the research behind this under a project funded by the European Union. In order for the viewer to work, it is necessary to have an eye-tracking input device, i.e, a Tobii EyeX compatible device. The software is open-source and free to use by anyone who wants to explore images with depth in a new way.
