本文提出了一个系统，用于预测用户将从图标工具栏中选择的图标，基于命令使用频率和鼠标轨迹。该系统在两个重要方面与以前的系统不同：首先，预测系统不会启动任何操作。相反，它预测鼠标移动的位置，并巧妙地“建议”一个命令供用户验证。第二，系统在进行预测时考虑命令被使用的相对可能性。最初的测试表明，一个只预测最常用图标选择的系统比一个预测所有选择的系统更好。一项对12名使用鼠标和10名使用触控板的测试用户进行的研究发现，这种“有限预测系统”有很大的好处。“该系统使触控板用户发出命令的时间平均减少了41%，鼠标用户减少了25%。触控板用户（而不是鼠标用户）更喜欢预测系统，而不是传统的指向方式。这些结果表明，像这里描述的预测系统有可能减少发布命令所需的时间和精力。该系统的实用性似乎在笔记本电脑和其他使用触控板作为主要定点设备的设备中尤其重要。
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 prediction system such as the one described here has the potential to reduce the time and effort required to issue commands. The utility of the system appears to be especially great in laptops and other devices that use trackpads as their primary pointing devices.
