Description
本發明相關於一種應用於虛擬實境之電競座艙,尤指一種可在虛擬實境應用中提供高自由度顯示、自動視角切換、自動環繞音效控制,以及情境系統之電競座艙。
虛擬實境(virtual reality, VR)是利用電腦技術模擬出一個立體且高擬真的三維空間,當使用者穿戴特殊顯示裝置進入後,會產生好像處在現實中的錯覺。在這虛擬實境空間中,操作者可以和虛擬物件或其他玩家互動。由於VR應用強調的是使用者在虛擬世界中的沉浸感,因此除了須滿足在虛擬世界中的操控駕馭之外,更希望獲得的不僅只是視覺以及聲音的感受,進一步也希望能夠同時提升人體五感的體驗。
應用於虛擬實境之電競座艙包含一顯示裝置、設置於一底座上之一可調式座椅、一自由度調整裝置,以及一系統端。該自由度調整裝置包含複數個垂直軌道,設置於該底座上;複數個環狀軌道,以可移動方式架設於該複數個垂直軌道上,用來透過沿著該複數個垂直軌道上下移動來提供一垂直方向的一第一自由度,以及透過在該複數個垂直軌道左右轉動來提供一水平方向的一第二自由度;一視線偵測裝置,設置於該複數個環狀軌道中一第一環狀軌道上,用來在一使用者坐上該可調式座椅後偵測該使用者的視線變化或頭部角度以提供一視線資料;以及一顯示器調整裝置,以可移動方式架設在該複數個環狀軌道中一第二環狀軌道上,用來乘載該顯示裝置並提供相關於該顯示裝置之仰角的一第三自由度。該系統端包含一主機和一微控制器。主機用來提供一虛擬實境應用所需之一影音資料。該微控制器用來依據該影音資料來控制該可調式座椅之角度和傾斜度、控制該複數個環狀軌道沿著該複數個垂直軌道上下移動以調整該顯示裝置的高度,以及控制該複數個環狀軌道在該複數個垂直軌道上左右轉動以調整該顯示裝置的方位。
第1圖為本發明實施例中一種應用於虛擬實境之電競座艙100的功能方塊圖。電競座艙100包含一系統端10、一可調式座椅20、一顯示裝置30、一自由度調整裝置40、一環繞音響組50、一情境營造裝置60,以及一操作平台70。
系統端10包含一主機12、一圖像處理單元14,以及一微控制器16。主機12可提供不同VR應用所需之影音資料,圖像處理單元14可處理主機12所提供之VR影像資料以呈現在顯示裝置30上,而微控制器16可依據主機12所提供之VR影音資料來控制電競座艙100中各元件以提供相對應之視覺、音響和情境效果。在本發明實施例中,在不妨礙VR應用的前提下,系統端10可設置在電競座艙10中任何合適位置。然而,系統端10之實作方式並不限定本發明之範疇。
第2A圖至第2C圖為本發明實施例電競座艙100中可調式座椅20、顯示裝置30和自由度調整裝置40實作方式之外觀示意圖。可調式座椅20可設置在一底座5上,微控制器16(未顯示在第2A圖至第2C圖中)可依據主機12(未顯示在第2A圖至第2C圖中)所提供之VR影音資料來控制可調式座椅20內設置之旋轉馬達22和傾斜度控制器24(可設置於可調式座椅20內),進而在特定VR應用的過程中改變可調式座椅20之角度和傾斜度。自由度調整裝置40包含環狀軌道A1
~AM
、垂直軌道B1
~BN
、視線偵測裝置C1
~CP
,以及一顯示器調整裝置44,其中M、N和P為大於1之整數。垂直軌道B1
~BN
固定在底座5上,用來乘載環狀軌道A1
~AM
。當環狀軌道A1
~AM
以可移動方式架設於垂直軌道B1
~BN
上:當環狀軌道A1
~AM
沿著垂直軌道B1
~BN
上下移動時,可在VR應用中提供垂直方向的自由度,如第2A圖和第2B圖所示;當環狀軌道A1
~AM
在垂直軌道B1
~BN
左右旋轉時,可在VR應用中提供水平環繞的自由度,如第2B圖和第2C圖所示。顯示裝置30包含螢幕D1
~DQ
(Q為正整數),其固定於顯示器調整裝置44之上,而顯示器調整裝置44以可移動方式架設在環狀軌道A1
~AM
之上。顯示器調整裝置44因角度問題未顯示在第2A圖至第2C圖中,但在說明書後續內容和圖式將會說明其實施方式。為了說明目的,第2A圖至第2C圖顯示了M=2、N=3、P=4和Q=3時之實施例,然而M、N 、P和Q之值並不限定本發明之範疇。
第3A圖和第3B圖為本發明實施例電競座艙100中座椅20、顯示裝置30和自由度調整裝置40實作方式之側視圖。在此實施例中,顯示器調整裝置44可包含垂直滑軌45、滑塊46、搖桿47,以及連桿48等元件以控制螢幕D1
~D3
之作動。垂直滑軌45固定在環狀軌道A1
~A2
中至少一環狀軌道上,而滑塊46可在垂直滑軌45內做垂直方向的移動。每一搖桿47包含兩個可旋轉接點J1
和J2
,可旋轉接點J1
連結至顯示裝置30中一相對應螢幕上方,而可旋轉接點J2
連結至相對應垂直軌道45。連桿48包含一可旋轉接點J3
和一不可旋轉接點J4
,可旋轉接點J3
連結至顯示裝置30中一相對應螢幕下方,而不可旋轉接點J4
固定在相對應滑塊46上。視線偵測裝置C1
~C4
可包含複數個相機或紅外線感測器,用來在使用者坐上可調式座椅20後隨時偵測使用者的視線變化或頭部角度。依據視線偵測裝置C1
~C4
提供的視線資料,顯示器調整裝置44可透過滑塊46在垂直滑軌45內的移動來調整螢幕D1
~DQ
的仰角,進而在VR應用中提供偏擺(yaw)的自由度。本發明之顯示器調整裝置44可採用不同機構來調整螢幕D1
~DQ
的仰角,第3A圖和第3B圖所示之實施例並不限定本發明之範疇。
第4A圖和第4B圖為本發明實施例電競座艙100中座椅20、顯示裝置30和環繞音響組50實作方式之示意圖。如第4A圖之上視圖所示,環繞音響組50包含複數組揚聲器E1
~ER
(R為大於1之整數),設置於環狀軌道A1
~AM
上不同位置以提供環繞音效。如第4B圖之外觀圖所示,顯示裝置30之螢幕D1
~DQ
可設置在環狀軌道A1
上,而環繞音響組50可設置在環狀軌道A2
上。微控制器16可依據主機12所提供之VR影音資料來控制環繞音響組50中不同音響之音量和音效以提供相對應之環繞立體聲。為了說明目的,第4A圖和第4B圖顯示了R=6時之實施例,然而環繞音響組50所包含音響數量和在環狀軌道上之設置位置並不限定本發明之範疇。
第5A圖和第5B圖為本發明實施例中可調式座椅20、顯示裝置30、自由度調整裝置40和環繞音響組50作動時之示意圖。假設依據目前VR應用的內容,在使用者的正左方和正右方需要製造特定音效,此時環繞音響組50中的音響E3
和E6
會運作,而其它音響不會發聲。若視線偵測裝置C1
~C4
判斷使用者的視線從身體正前方的螢幕D2
移向身體右前方的螢幕D3
(如第5A圖所示),此時系統端10之微控制器16(未顯示在第5A圖和第5B圖中)會控制環狀軌道A1
~AM
以順時針方向做相對應轉動,使得架設在環狀軌道A1
~AM
上的營幕D1
~D3
和音響E1
~E6
都能隨著使用者視線轉動(如第5B圖所示),如此環繞音響組50中的音響E3
和E6
會維持在使用者的正左方和正右方製造特定音效。此外,可調式座椅20可利用旋轉馬達22(如第3A圖和第3B圖所示)來調整使用者的身體角度。透過控制可調式座椅20、顯示裝置30和環繞音響組50隨著使用者視線自動旋轉,使用者在VR應用中不需要分神去切換至其它螢幕的視角,而環繞立體聲之效果也不會因為使用者身體方位調整而產生混亂。
人眼在視物的過程中並不會注意到全部的細節,而是只有中間視覺焦點附近是清晰的,因此即使目標物在人眼視角涵蓋範圍內,人還是習慣會轉頭朝向真正要注意的目標。除了前述提及隨著使用者視線自動旋轉顯示裝置30之位置,本發明另可使用注視點渲染技術(foveated rendering) 來減輕系統運算負擔或降低對電腦性能的要求。第6A圖至第6C圖為本發明實施例中顯示裝置30使用注視點渲染技術時之示意圖。第6A圖至第6C圖分別顯示使用者的視線從螢幕D2
移向螢幕D3
的過程,而螢幕D1
~D3
中所示的數字代表在使用者視線轉動的過程中每一螢幕的解析度。在第6A圖所示的狀態下,視線偵測裝置C1
~C4
判斷使用者正視前方,此時負責人眼可專注範圍之螢幕D2
