Two experiments examined the effects of interactive tutorial features (compared to “passive” features) on learning spatial tasks, an area seldom explored in interactivity research. Experiment 1 results indicated that for simple spatial tasks, interactive tutorials hindered learning for participants of higher spatial ability but improved learning for lower-ability participants. This interaction ...

In this paper, the possibilities of using visual and textual information are investigated to improve the ranking of photos from Flickr about famous places. We have elaborated improved textual features based on standard ones and visual features e.g. face feature for measure the relative face area on the images. These heuristic features have been used for the solution in the MediaEval 2013 Retrie...
