Popis: This article presents a system for predicting the icon a user will select from an icon toolbar, based on command use frequency and mouse trajectory. The system differs from previous systems in 2 important ways: First, the prediction system does not initiate any action. Instead, it predicts where the mouse is moving and subtly "suggests" a command for the user to verify. Second, the system takes into account the relative likelihood of commands being used when making its predictions. Initial testing suggested that a system that only predicted the most frequently used icon choices was better than one that predicted all choices. A study with 12 test users using a mouse and 10 using a trackpad found substantial benefits of this "limited prediction system." The system resulted in a mean reduction in time to issue a command of 41% for trackpad users and 25% for mouse users. Trackpad users, but not mouse users, preferred the prediction system to the traditional way of pointing. These results suggest that a predic...
