本研究主要以虛擬實境裝置，檢測不同經驗水平的球員在面對虛擬進攻者在籃球中
變化動作方向的跳投情形下，預測判斷的精準度是否存有差異，且以數學模型τ 來
做為評估。本研究招募8 名一般大專生與8 名大專校隊籃球員，以虛擬實境裝置呈
現三種不同類型的跳投動作(非欺瞞動作、換手變向突破、跨下後側步) ，同步與動
作分析系統擷取身體肢段變化訊號，因而分析出質心τ。並且以獨立樣本t 檢定
(Independent Sample t test)比較兩個不同經驗組別（校隊與一般生組）於不同動作類
型—真實或欺瞞的啟動時間、預測錯誤方向上的初始移動的距離與虛擬進攻者到攔
截區域最終的距離差的差異，顯著水準將定為p <.05。研究結果當中，校隊生與一
般生相比在面對不同種類的動作時，啟動時間上皆有顯著性的差異;在面對欺瞞對做
時，校隊生在預測錯誤方向上的初始移動的距離皆比一般生更長且有顯著性的差異。
且與防守者與虛擬進攻者到攔截區域最終的距離差方面，無變向運球突破，校隊生
的平均距離差皆較小，且統計結果顯示有顯著的差異。面對欺瞞動作時，在換手變
向運球突破中校隊生的平均距離差皆較小，但在統計結果顯示，在最終向左向時沒
有顯著的差異;而在向右時有顯著的差異。面對跨下運球後側步時，一般生在最終向
左或向右的距離差都高於校隊生且在統計上有顯著的差異。另外，知覺τ 與動態τ
之間的關係的結果顯示，校隊生在面對不同類型動作，相關性的平均值都高於一般
生，但在統計結果顯示，並非皆有顯著上的差異。總結來說，校隊生在面對不同類
型的動作時，都能更快的判斷出進攻意圖且最終與進攻者的距離差較小;校隊生與一
般生相比，在面對欺瞞與非欺瞞影像時似乎更適應於接收誠實的訊號。

This research mainly uses virtual reality devices to detect whether there is a
difference in the accuracy of prediction and judgment when players with different
levels of experience facing a jump shot in which a virtual attacker changes the
direction of action in basketball, using the mathematical model τ as an evaluation.
This study recruited 8 junior college students and 8 college basketball players to
present three different types of jump shots with virtual reality devices, using
synchronized and the motion analysis system to capture the change signal of the
body limbs, and thus analyzes the center of mass τ. Compared with general
students, there is a significant difference in the starting time of the school team
students when facing different types of actions. And in terms of the final distance
difference between the defender and the virtual attacker to the interception area,
the average distance difference between the school team students is small, and the
statistical results show significant differences. In the face of deception, the average
distance difference of the lieutenant school students in the change of hands and
dribble breakthrough is small, but the statistical results show that there is no
significant difference in the final leftward direction; while there is a significant
difference in the rightward direction. Compared with the general students, the
school team students face deception and non-deception It seems to be more
suitable for receiving honest signals when taking images.
