Description

重定向虛擬實境空間系統及其方法 Redirecting virtual reality space system and method
一種重定向系統及其方法,尤指一種應用於虛擬實境領域之重定向虛擬實境空間系統及其方法。 A redirection system and method, especially a redirection virtual reality space system and method applied in the field of virtual reality.
在科技發展快速的時代,以往需要透過電視或電腦螢幕呈現之電玩已無法滿足現今的使用者。為了讓使用者得到更真切的遊戲感受,虛擬實境遊戲孕育而生。各家廠商皆朝向讓穿戴著虛擬實境裝置的使用者猶如身臨其境,且不受真實空間所限制之方向進行改善。 In the era of rapid technological development, video games that used to be presented on TV or computer screens cannot satisfy today's users. In order to let users get a more real game experience, virtual reality games are born. Various manufacturers are making improvements in the direction of making users wearing virtual reality devices feel as if they are on the scene without being restricted by real space.
市面上有一種柱元陣列式全向的跑步機,包括行走平台和陣列式全向驅動元件。此跑步機可用於虛擬實境領域中為用戶提供無限的自由行走空間。跑步機的全向驅動元件採用柱元陣列式結構。此柱元陣列式結構運轉慣性小且對轉彎半徑無限制。因此跑步機可準確快速地跟蹤用戶的運動。跑步機藉由幾個不同高度、不同傾斜角的行走平台相互拼接,來模擬各種複雜地形中的行走運動及上下台階運動。然而,使用者於使用時須將身體吊掛著來搭配跑步機使用。這樣的使用方式會讓使用者有被帶著移動,而非由自身自主移動的感覺。 There is a column element array type omnidirectional treadmill on the market, which includes a walking platform and an array type omnidirectional driving element. This treadmill can be used in the field of virtual reality to provide users with unlimited free walking space. The omnidirectional driving element of the treadmill adopts a column element array structure. The column element array structure has small operating inertia and has no restriction on turning radius. Therefore, the treadmill can accurately and quickly track the user's movement. The treadmill uses several walking platforms with different heights and different inclination angles to be joined to each other to simulate the walking movement and the movement of up and down steps in various complex terrain. However, the user must hang his body to match the treadmill when using it. This way of use will give the user the feeling of being carried and moved, rather than moving by themselves.
又如紐約州立大學石溪分校、英偉達和Adobe於GTC 2018大會上所發表之重定向行走技術,其原理是利用了人類視覺的掃視抑制的 自然特性。掃視抑制係為人類視覺因為產生短暫的類失明,而隱藏了小幅度的轉動。當使用者向前行走並環視場景時,場景將慢慢地由系統端往目標位置多旋轉幾度。使用者每次環視均只多旋轉幾度,讓使用者在不知不覺中改變了物理世界的行走方向,進而創建一種彷彿以直線行走在虛擬空間的幻覺。然而,此技術具有一些問題,如:此技術藉由依靠相對視覺誤差欺騙大腦,讓使用者呈現在物理空間中走一小步,但在虛擬世界中卻邁出一大步,因而讓使用者的體驗感受不夠擬真;此技術需要夠大的物理空間讓使用者使用;當使用者行走並環視場景時,場景的旋轉可能會使使用者暈眩。由以上各種問題可知此是以確有加以改善之必要課題。 Another example is the redirection walking technology published by the State University of New York, Stony Brook, NVIDIA and Adobe at the GTC 2018 conference. The principle is to use the saccade suppression of human vision. Natural characteristics. Saccadic inhibition is that human vision hides a small amount of rotation due to transient blindness. When the user walks forward and looks around the scene, the scene will slowly rotate a few more degrees from the system to the target position. The user only rotates a few more degrees each time he looks around, allowing the user to unknowingly change the walking direction of the physical world, thereby creating an illusion of walking in a virtual space in a straight line. However, this technology has some problems. For example, this technology deceives the brain by relying on relative visual errors, allowing the user to take a small step in the physical space, but takes a big step in the virtual world, thus allowing the user The experience is not realistic enough; this technology requires a large enough physical space for the user to use; when the user walks and looks around the scene, the rotation of the scene may make the user dizzy. From the above problems, it can be seen that this is a necessary issue to be improved.

請參閱圖3,圖3為本發明重定向虛擬實境空間方法之一具體實施例之流程圖。於一具體實施例中,本發明之重定向虛擬實境空間方法包含以下步驟:S10:提供承載使用者之步行平台10,步行平台10設置有複數個轉盤組件100以供使用者於複數個轉盤組件100上移動;S12:偵測使用者之面對方向以及位於步行平台10的位置以產生定位訊號S1;S14:根據定位訊號S1產生重定向訊號S3,此重定向訊號S3包含各個轉盤組 件100所需之旋轉方向、角度及速度;以及S16:根據重定向訊號S3旋轉各個轉盤組件100,使使用者朝向鄰近的轉盤組件100移動;在使用者持續使用本發明時,本發明將會持續的或間歇的執行以上步驟,並會再從步驟S16回到步驟S12繼續運作。於另一具體實施例中,重定向訊號S3係根據定位訊號S1及由虛擬實境穿戴式裝置2產生具有使用者的欲行路徑的欲行訊號S2所產生。 Please refer to FIG. 3, which is a flowchart of a specific embodiment of a method for redirecting a virtual reality space according to the present invention. In a specific embodiment, the method for reorienting the virtual reality space of the present invention includes the following steps: S10: providing a walking platform 10 for carrying users, and the walking platform 10 is provided with a plurality of turntable assemblies 100 for the user to move on the plurality of turntables The component 100 moves up; S12: detects the user’s facing direction and the position on the walking platform 10 to generate a positioning signal S1; S14: generates a redirection signal S3 according to the positioning signal S1, and the redirection signal S3 includes each turntable group Rotation direction, angle and speed required for the piece 100; and S16: Rotate each turntable assembly 100 according to the redirection signal S3 so that the user moves toward the adjacent turntable assembly 100; when the user continues to use the present invention, the present invention will The above steps are executed continuously or intermittently, and the operation will continue from step S16 back to step S12. In another specific embodiment, the redirection signal S3 is generated based on the positioning signal S1 and the desire signal S2 generated by the virtual reality wearable device 2 having the user's desired path.
藉由上述之步驟,請參閱圖4,圖4為本發明重定向虛擬實境空間方法之一實施例之使用示意圖。圖4中的圖示分別代表:實心圓點為使用者欲移動到的位置、空心圓點為使用者原本的位置、實線箭頭為使用者欲行走的路徑,以及虛線箭頭為轉盤組件100所旋轉的方向。在此實施例中,使用者在虛擬實境中認知自身所行走的路徑為直線。然而,使用者實際上卻是在三個不同的轉盤組件100上移動。為了清楚解說,將轉盤組件100加上編號a、b、c。使用者實際上所行走的路徑係從a轉盤組件100移動至b轉盤組件100。接著,b轉盤組件100旋轉讓使用者面對c轉盤組件100。最後,使用者從b轉盤組件100移動至c轉盤組件100。需注意的是,於此實施例中,示意圖中的使用者可以持續的走動,而不需要站在b轉盤組件100後待b轉盤組件100旋轉至使使用者面對c轉盤組件100後才開始繼續走動。亦即轉盤組件100的旋轉並不會影響使用者的移動。 With the above steps, please refer to FIG. 4, which is a schematic diagram of an embodiment of the method for redirecting a virtual reality space according to the present invention. The icons in Figure 4 respectively represent: the solid circle is the position the user wants to move to, the hollow circle is the user's original position, the solid arrow is the path the user wants to walk, and the dashed arrow is the position of the turntable assembly 100 The direction of rotation. In this embodiment, the user recognizes that the path he walks is a straight line in the virtual reality. However, the user actually moves on three different turntable assemblies 100. For clear explanation, the turntable assembly 100 is numbered a, b, and c. The path actually traveled by the user moves from the a turntable assembly 100 to the b turntable assembly 100. Then, the b-turntable assembly 100 is rotated so that the user faces the c-turntable assembly 100. Finally, the user moves from the b turntable assembly 100 to the c turntable assembly 100. It should be noted that in this embodiment, the user in the schematic diagram can walk continuously, without standing behind the b-turntable assembly 100 and waiting for the b-turntable assembly 100 to rotate until the user faces the c-turntable assembly 100. Keep walking around. That is, the rotation of the turntable assembly 100 does not affect the movement of the user.
請複參閱圖3,在本發明之一具體實施例中,於步驟S12後,更包含以下步驟:S13:偵測使用者所處位置與各個轉盤組件100之盤周緣間是否小於限定距 離;當偵測使用者所處位置與各個轉盤組件100之盤周緣間小於限定距離時,則產生定位訊號S1。若當偵測使用者所處位置與各個轉盤組件100之盤周緣間未小於限定距離時,則重新偵測使用者之面對方向以及位於步行平台10的位置。然而,不管使用者所處位置與各個轉盤組件100之盤周緣間是否小於限定距離,轉盤組件100皆可持續作動。此步驟S13係藉由限定距離來決定是否要再次提供定位訊號S1。藉由步驟S13讓使用者所處位置附近之各個轉盤組件100能有足夠的反應時間,進而提高使用者於步行平台10上移動的流暢度。 Please refer to FIG. 3 again.

If it is detected that the distance between the position of the user and the periphery of each turntable 100 is not less than the limited distance, the facing direction of the user and the position on the walking platform 10 are detected again. However, regardless of whether the position of the user is less than a limited distance from the periphery of each turntable 100, the turntable 100 can continue to operate. This step S13 determines whether to provide the positioning signal S1 again by limiting the distance.

請參閱圖7,圖7為本發明重定向虛擬實境空間方法之一具體實施例之流程圖。在一具體實施例中,於步驟S14中更包含以下子步驟:S140:接收定位訊號S1;S145:根據定位訊號S1之使用者所在位置,判斷使用者與步行平台10周緣間是否小於限定距離;當判斷使用者與步行平台10周緣間小於限定距離時發出安全訊號S5,並執行步驟S146 S146:接收安全訊號S5,增加使用者的站立位置所對應的轉盤組件100之旋 轉速度,並回到步驟S140;當判斷使用者與步行平台10周緣間未小於限定距離時發出安全訊號S5,則執行步驟S143 S143:產生重定向訊號S3;藉由上述步驟,確保使用者能持續保持移動於步行平台10上。 Please refer to FIG. 7, which is a flowchart of a specific embodiment of a method for redirecting a virtual reality space according to the present invention. In a specific embodiment, step S14 further includes the following sub-steps: S140: receiving the positioning signal S1; S145: judging whether the user and the periphery of the walking platform 10 are less than a limited distance according to the location of the user in the positioning signal S1; When it is determined that the distance between the user and the periphery of the walking platform 10 is less than the limited distance, a safety signal S5 is issued, and steps S146 and S146 are received: the safety signal S5 is received, and the rotation of the turntable assembly 100 corresponding to the standing position of the user is increased. Turn speed and return to step S140; when it is determined that the distance between the user and the periphery of the walking platform 10 is not less than the limited distance, the safety signal S5 is issued, then steps S143 and S143 are generated: a redirection signal S3 is generated; Keep moving on the walking platform 10 continuously.
於上述之具體實施例中,重定向訊號S3係根據下列情況之優先順序來產生:1.使用者與步行平台10周緣是否小於限定距離;2.轉盤組件100所需的轉動角度是否超過感知角度;3.使用者是否往各轉盤組件100之盤面中心移動;其中,感知角度係為使用者開始查覺到轉盤組件100在旋轉的角度。於本發明之一具體實施例中,感知角度為30度。於本發明再一具體實施例中,重定向訊號S3係由控制單元14根據定位訊號S1及欲行訊號S2進行計算而得。 In the above specific embodiment, the redirection signal S3 is generated according to the priority order of the following situations: 1. Whether the user and the periphery of the walking platform 10 are less than a limited distance; 2. Whether the rotation angle required by the turntable 100 exceeds the sensing angle 3. Whether the user moves to the center of the disk surface of each turntable assembly 100; wherein, the perception angle is the angle at which the user starts to perceive the turntable assembly 100 to rotate. In a specific embodiment of the present invention, the perception angle is 30 degrees. In another specific embodiment of the present invention, the redirection signal S3 is calculated by the control unit 14 based on the positioning signal S1 and the desired signal S2.
於一較佳具體實施例中,雖然使用者的感知角度有限,但當轉盤組件100的盤面較大時,由於使用者在轉盤組件100上移動的時間跟距離都會增加,而讓轉盤組件100能在有限的旋轉速度下,旋轉更大的角度但卻不會被使用者察覺。另外,當使用者移動速度較快時,使用者對於轉盤組件100正在移動的敏感度會下降。因此轉盤組件100的旋轉速度和角度可以在不被使用者察覺到的情況下進行增加。 In a preferred embodiment, although the user’s perception angle is limited, when the disk surface of the turntable assembly 100 is large, the time and distance the user moves on the turntable assembly 100 will increase, so that the turntable assembly 100 can With a limited rotation speed, it can rotate at a larger angle without being noticed by the user. In addition, when the user moves faster, the user's sensitivity to the movement of the turntable assembly 100 will decrease. Therefore, the rotation speed and angle of the turntable assembly 100 can be increased without being noticed by the user.
請參閱圖8,圖8係為本發明重定向虛擬實境空間方法之一具體實施例之使用示意圖。圖8中的圖示分別代表:實心圓點為使用者欲移動到的位置、空心圓點為使用者原本的位置、實線箭頭為使用者欲行走的路徑,以及虛線箭頭為轉盤組件100所旋轉的方向。為了更加清楚解說,將轉 盤組件100加上編號d、e、f、g。在此實施例中,使用者在虛擬實境中認知自身所行走的路徑為直線。使用者實際上所行走的路徑係從d轉盤組件100移動至e轉盤組件100。然而,若要讓使用者繼續往前走,則必須轉動e轉盤組件100,以讓使用者往f轉盤組件100或g轉盤組件100移動。但如圖7中所示,若要讓使用者往f轉盤組件100移動,則e轉盤組件100必須旋轉180度。而若要讓使用者往g轉盤組件100移動,則e轉盤組件100則必須旋轉45度。在此兩種情況下,本發明將選擇讓使用者往所需旋轉角度較小的g轉盤組件100移動。這樣的選擇係為了讓使用者不會對於旋轉的感受太大。 Please refer to FIG. 8. FIG. 8 is a schematic diagram of a specific embodiment of a method for redirecting a virtual reality space according to the present invention. The icons in Figure 8 respectively represent: the solid circle is the position the user wants to move to, the hollow circle is the user's original position, the solid arrow is the path the user wants to walk, and the dashed arrow is the position of the turntable assembly 100 The direction of rotation. In order to explain more clearly, we will turn The disk assembly 100 is numbered d, e, f, and g. In this embodiment, the user recognizes that the path he walks is a straight line in the virtual reality. The path actually traveled by the user moves from the d-turntable assembly 100 to the e-turntable assembly 100. However, if the user wants to move forward, he must rotate the e-disk assembly 100 so that the user can move to the f-disk assembly 100 or the g-disk assembly 100. However, as shown in FIG. 7, if the user wants to move the f-turntable assembly 100, the e-turntable assembly 100 must be rotated 180 degrees. To allow the user to move to the g-turntable assembly 100, the e-turntable assembly 100 must be rotated by 45 degrees. In both cases, the present invention will choose to allow the user to move the g-disk assembly 100 with a smaller required rotation angle. This choice is to prevent the user from experiencing too much rotation.
然而,旋轉45度將超過感知角度30度,請參考圖9,圖9為本發明重定向虛擬實境空間方法之一具體實施例之使用示意圖。圖9中的圖示分別代表:實心圓點為使用者欲移動到的位置、空心圓點為使用者原本的位置、實線箭頭為使用者欲行走的路徑,以及虛線箭頭為轉盤組件100所旋轉的方向。並且為了更加清楚解說,將轉盤組件100加上編號d、e、f、g。為了讓使用者不要感受到旋轉組件100正在旋轉,將旋轉角度從45度修正成30度。意即讓使用者從往g轉盤組件100之盤面中心修正成往盤面邊緣移動。雖然轉盤組件100在轉動時係以讓使用者往盤面中心移動為目標,但為了考慮到使用者的使用感受,則需將旋轉角度重新計算並修正成不超過感知角度。 However, the rotation of 45 degrees will exceed the perception angle of 30 degrees. Please refer to FIG. 9, which is a schematic diagram of a specific embodiment of the method for reorienting the virtual reality space of the present invention. The icons in FIG. 9 respectively represent: the solid circle is the position the user wants to move to, the hollow circle is the user's original position, the solid arrow is the path the user wants to walk, and the dashed arrow is the position of the turntable assembly 100 The direction of rotation. In order to explain more clearly, the turntable assembly 100 is numbered d, e, f, and g. In order to prevent the user from feeling that the rotating assembly 100 is rotating, the angle of rotation is corrected from 45 degrees to 30 degrees. This means that the user is allowed to move from the center of the disk surface of the g turntable assembly 100 to the edge of the disk surface. Although the turntable assembly 100 aims to allow the user to move to the center of the disk surface when rotating, in order to take into account the user's experience, the rotation angle needs to be recalculated and corrected to not exceed the perceived angle.
於一較佳具體實施例中,轉盤組件100的旋轉速度將會與使用者所處的位置與承載使用者的旋轉組件100之盤面中心距離成反比。因為當旋轉角度相同時,位於盤面中心位置之旋轉所位移的距離會小於位於盤面周緣位置。因此若使用者位於盤面周圍的位置,則必須降低轉盤組件100 的旋轉速度,以避免讓使用者感受到轉盤組件100正在旋轉。基於前述理由,控制元件14根據定位訊號S1進行計算重定向訊號S3時,同時預估了使用者位於各個轉盤組件100上移動的時間,並以此判斷轉盤組件100的旋轉速度。於另一具體實施例中,上述之重定向訊號S3係由控制單元14根據定位訊號S1及欲行訊號S2進行計算而得。 In a preferred embodiment, the rotation speed of the turntable assembly 100 will be inversely proportional to the position of the user and the distance between the center of the disk surface of the rotating assembly 100 carrying the user. Because when the rotation angle is the same, the distance of the rotation at the center of the disk surface will be smaller than that at the periphery of the disk surface. Therefore, if the user is located around the disc surface, the turntable assembly 100 must be lowered The rotation speed is to avoid the user feeling that the turntable assembly 100 is rotating. For the foregoing reasons, when the control element 14 calculates the redirection signal S3 according to the positioning signal S1, it also estimates the time when the user moves on each turntable assembly 100, and judges the rotation speed of the turntable assembly 100 accordingly. In another specific embodiment, the aforementioned redirection signal S3 is calculated by the control unit 14 according to the positioning signal S1 and the desired signal S2.
相較於習知技術,本發明之重定向虛擬實境空間系統1及其方法藉由不同的轉盤組件100旋轉所需之旋轉方向、角度及速度,讓使用者在不知不覺中被限制在特定的物理空間中。因此不需要太大的物理空間,就可以讓使用者盡情體驗虛擬實境。除此之外,使用者可以正常及自主的方式進行移動,不需如習知技術般需藉由牽引來控制使用者的身體。藉由本發明,能讓使用者在體驗虛擬實境時更有身臨其境的感受。 Compared with the prior art, the redirecting virtual reality space system 1 and method of the present invention uses different rotation directions, angles, and speeds required for the rotation of the turntable assembly 100, so that the user is unconsciously restricted to In a specific physical space. Therefore, users can enjoy the virtual reality without much physical space. In addition, the user can move in a normal and autonomous manner, and does not need to control the user's body by traction as in the conventional technology. With the present invention, the user can have a more immersive experience when experiencing virtual reality.
藉由以上具體實施例之詳述,係希望能更加清楚描述本發明之特徵與精神,而並非以上述所揭露的具體實施例來對本發明之範疇加以限制。相反地,其目的是希望能涵蓋各種改變及具相等性的安排於本發明所欲申請之專利範圍的範疇內。 Based on the detailed description of the above specific embodiments, it is hoped that the characteristics and spirit of the present invention can be described more clearly, rather than limiting the scope of the present invention by the specific embodiments disclosed above.
