The overall goal of the Deepview Project is to create displays that can actively support and enhance the perception of the user. We achieve this through the use of real-time eye-tracking, which can be used to adapt what is shown on the display in response to the user’s gaze. Through this technique we are able to influence the perception of the user by controlling what is seen and where it is seen, even without the user noticing the manipulation. Since the manipulation is happening on a perceptual level and in response to the user’s gaze, we call this a perceptual gaze-contingent display.

With our research we have managed to enhance the perception of depth, as well as the perception of colour and contrast. These enhancements can benefit a wide range of applications. For example, astronomers extract their insights from looking at different representations of their measures from the universe, doctors’ diagnostics often depend on the ability to see and interpret patterns in a magnetic resonance images (MRIs) or tomographic images (CTs), and security guard’s effectiveness depends on being able to spot crime on a large array of CCTV images. Applying these results in a productive environment is now more achievable than ever. Affordable and easy to use eye-tracking technology is starting to reach the consumer market, so eye-tracking applications can now easily be deployed to a wide audience.

While our research is only starting to uncover the true potential of perceptual gaze-contingent displays, we firmly believe that we are close to a future where the display in front of you will not just passively present content but will actively augment your perception.
