雖然目前已有許多使用Fitts’ Law實驗以及模型的研究，但並沒有針對現有績效評估指標進行分析的研究。本研究主要目的為使用Fitts’ Law模組適應性來探討人員績效變異性。本研究招募了14位非人因工程領域、平均年齡為23.86歲(標準差 = 3.03)之受試者，本研究採用兩種任務進行實驗(距離任務以及綜合測試)，實驗中的裝置以動感式無線空中滑鼠作為控制器，讓任務中需點擊的游標以一維向度與離散的方式出現，並將各個實驗接劃分成三種速度，讓受測者使用慣用手以及非慣用手進行測試。本研究分析了25種績效指標，並將此25種績效指標區分成三個群組分別為速度組、準確組以及複合組，本研究將所有測試得到之數據以平均數的方式進行成對比較排列。並且產生可以被使用的評估方式以及建議。結果建議了平均值與移動平均之變異數、整體誤差率以及綜合生產率(grand throughput)。生產率(throughput)是一個從Fitts’ Law被使用以來扮演著一個被推崇的綜合性績效指標，其可以用來衡量速度的績效以及生產率的非零截距線性迴歸方程式，並強烈的推薦將每一次的實驗數據進行線性的迴歸分析。最後，本研究亦提出可使用製程能力有助於簡單的進行運算進行評估並替代落點位置的結果。

Although many studies have been done by applying Fitts’ Law experiment and modelling, there has been no work that analyzing the existing performance measures together. The aim of this research was to investigate the human performance measures based on Fitts’ Law model adaptations with respect to human performance variability. Fourteen novice participants recruited as the voluntary participants with the average age was 23.86 years (SD = 3.03). The experiment conducted with two type of tasks (distance task and combination task), both dominant and non-dominant hand, and three different pointer speeds by applying one-dimensional discrete pointing task, using an air-mouse as the only pointing device. There were twenty-five performance measures, classified into the speed, accuracy, and the composite group were analyzed in this study. The investigation was mainly based on the mean order result of the pairwise comparison. It resulted the evaluation and recommendations of the performance measures to be used. The result recommends the report of average and coefficient of variation of the movement time, overall error percentage, and the grand throughput. The throughput as a composite performance measure was recommended to be used since the index of performance found to be a speed index of performance and the regression throughput was influenced by the non-zero intercept value in the linear regression equation. It was also strongly recommended to employ the data per trial to perform the linear regression analysis. Finally, the use of process capability was proposed because it might be useful to compliment the report due to its simple calculation and to substitute the report of landing position result.
