本文探讨了“力场”的使用，以方便计算机用户在指点任务中使用。第一项研究表明，通过使用看不见的力场来增强指向目标的功能，可以缩短指向时间，该力场会将屏幕光标扭曲到目标中心。进一步支持了力场的应用，因为我们展示了如何使用Fitts定律和力调整的难度指数来预测力增强指向的性能。在第二个研究中，比较了力场技术和粘性目标技术[20]在两种现实的指向情况下，其中涉及多个近距离放置的目标。结果表明，力场改善了瞄准性能，而粘性目标技术没有改善瞄准性能。
In this paper we explore the usage of "force fields" in order to facilitate the computer user during pointing tasks. The first study shows that pointing time can be reduced by enhancing a pointing target with an invisible force field that warps the screen cursor toward the target center. The application of force fields is further supported in that we show how performance of force enhanced pointing can be predicted by using Fitts' law and a force adjusted index of difficulty. In the second study, the force field technique is compared with the "sticky target" technique [20] in two realistic pointing situations which involve several closely placed targets. The results show that the force fields improve pointing performance and that the sticky target technique does not.
