Eyetracking |
improves image retrievalRecent experiments have shown that visual target selection is significantly faster with an eyetracker than with a mouse. This mechanism has now been developed into an interface for image retrieval in which the user is able to search a database of images for a target image just using eye movement. A network of pre-computed inter-image similarities are used to provide successive displays of thumbnail images that are similar to the images that attracted attention in previous displays. The VIDEO shows the fixations and saccades during a typical search. The target image is in the top left corner and the action stops as soon as the target image is retrieved.
