The practical meaning of Fitts’ law

The practical meaning of Fitts’ law for the HCI community was explained in the preface – it takes more timeto hit a target if it is further away or smaller. There is no reason making a big deal of it and it is definitely notworth the several hundred publications on the topic. Fights for the most exact formula predicting targetacquisition times do not bring any benefit and have no implication on practical design issues.Fitts’ law experiments suit perfectly for student exercises. The software is easy to program on any platform,the user study does not take much time, and the measured data are the base for exercising statisticalmethods. There are many pointing devices, mouse devices, trackballs, touchpads and joysticks, which allowmany variations for a different exercise in the next course.Of course the concept of limited information transmission from a human to a device has relevance forhuman computer interaction. Therefore it seems natural that the HCI community does research on this topic.However, the concept is well-known for more than half a century and there was a lot of psycho-motorresearch done already and therefore the concept is also well-understood, at least outside HCI.It seems that the motivation for Fitts’ law research by the HCI community is the scientific claim. Fitts’formula is the only non-trivial formula in HCI and has a relation to Shannon’s information theory which isdefinitely hard science. Therefore Fitts’ law could support the scientific claim of a community which mostlydeals with soft design issues. However, if people do research on a naïve level it can also prove the opposite.

在實踐意義費茨法則的HCI社區解釋在序言中-它需要更多的時間
要擊中目標，如果它更遠或更小，沒有理由作出大不了和它絕對不是。
值得數百出版物的話題。打架最準確公式預測目標
採集時間不會帶來任何好處，沒有任何意義實際設計問題。
費茨法則實驗完全滿足對於學生練習。該軟件易於程序在任何平台上，
用戶研究並不需要太多的時間，測量數據基礎行使統計
方法有許多指點設備，鼠標設備，軌跡球，觸摸板和操縱桿，這讓
許多變化對於不同的練習在下一療程。
當然，概念有限的信息傳輸從人到設備具有相關性，為
人機交互，所以很自然的人機交互社會並研究關於這一主題。
然而，這一概念眾所周知超過半個世紀，並有一個很大的心理運動
的研究已經完成，因此，概念也是很好理解的，至少外界HCI，
似乎動機費茨法則研究由HCI科學界索賠費茨
公式是唯一的非普通式人機交互，並且具有關係香農信息論這是
硬科學肯定。因此費茨法則可支持的社區裡面的科學索賠大多
涉及軟設計問題。但是，如果人們做研究上的幼稚程度它也可以證明相反。
