Past Projects When bigger is better. Why are two screens better than one for solving problems? You can only see a small part of one screen. That much screen space should not matter. But the effect on problem solving is actually quite large (for tasks that require integration of information across screens). We found that the effect can actually vary drammatically across situations and is overall driven by three factors: extra time taken to memorize content, the time to find content located externally, and the time to actively place copies/summaries of content into additional display areas. Solving big problems with a little brain. Estimates of visual working memory size put it around 2 to 5 chunks of information, depending on the person. That is a tiny amount of information. Yet, all humans can solving fairly complex visual problems, some in ways that are much more efficent than computers, integrating global information into local activities. How can that be done using such a small visual working memory? We collected and analyzed eye-tracking data and bulding computational models of visual problem solving to uncover the answer. |
