Context-aware gaze prediction applied to game level design, level-of-detail and stereo manipulation
Abstract
The prediction of visual attention can significantly improve many aspects of computer graphics and games. For example, image synthesis can be accelerated by reducing complex computations on non-attended scene regions. Current gaze prediction models often fail to accurately predict user fixations since they include limited information about the context of the scene; they commonly rely on low level image features such as luminance, contrast and motion. These features do not drive user attention reliably when interacting with an interactive synthetic scene, e.g. in a video game. In such cases the user is in control of the view-port consciously ignoring low level salient features in order to navigate the scene or perform a task. This dissertation contributes two novel predictive scene context-based models of attention that yield more accurate attention predictions than those derived from state-of-the-art methods. Both models presented take into account critical high level scene context fea ...
