Foveated sensors are multiresolution hardware devices that allow image data to be collected with higher resolution concentrated at a fixation point.
An advantage to using foveated sensor hardware is that the image collection and encoding can occur much faster than in a system that post-processes a high resolution image in software.
Standard gaze-contingent rendering (top row) updates the image according to the current gaze prediction.
Due to the system latency, during a saccade, there is a significant mismatch between the rendering and the actual gaze position (b, c).
For example, when viewing an image on a computer monitor, one may specify a fixation using a pointing device, like a computer mouse.
