什麼是全像投影?What is a hologram?

HoloLens 可讓您建立全像 影像,也就是像真實物件一樣,在世界周圍出現的燈光和音效物件。HoloLens lets you create holograms, which are objects made of light and sound that appear in the world around you like real objects. 全像投影會回應您的 注視手勢語音命令Holograms respond to your gaze, gestures, and voice commands. 他們甚至可以與您的 真實世界表面 互動。They can even interact with real-world surfaces around you. 透過全像投影,您可以建立屬於自己世界的數位物件。With holograms, you can create digital objects that are part of your world.

全像是由燈光和音效組成A hologram is made of light and sound

HoloLens 轉譯的全像是在使用者的眼睛前方,直接顯示于全像攝影框架中。The holograms that HoloLens renders appear in the holographic frame directly in front of the user's eyes. 全像是將燈光添加到您的世界,這表示您可以看到顯示器的光線和周圍的光線。Holograms add light to your world, which means that you see both the light from the display and the light from your surroundings. HoloLens 不會從您的眼睛中移除光線,所以無法使用黑色色彩來轉譯全像影像。HoloLens doesn't remove light from your eyes, so holograms can't be rendered with the color black. 相反地,黑色內容會顯示為透明。Instead, black content appears as transparent.

全像影像可以有許多不同的外觀和行為。Holograms can have many different appearances and behaviors. 有些是真實且穩固的,有些則是編排卡通和 ethereal。Some are realistic and solid, and others are cartoonish and ethereal. 您可以使用全像投影來醒目提示您的環境中的功能,或使用它們作為應用程式使用者介面中的元素。You can use holograms to highlight features in your surroundings or use them as elements in your app's user interface.

全像投影也 可以製作音效,看起來就像是來自您周圍的特定位置。Holograms can also make sounds, which will appear to come from a specific place in your surroundings. 在 HoloLens 上,音效來自兩個位于您的耳上方的喇叭,而不會加以涵蓋。On HoloLens, sound comes from two speakers that are located directly above your ears, without covering them. 就像顯示器一樣,喇叭是加總的,會在不封鎖環境音效的情況下引進新聲音。Similar to the displays, the speakers are additive, introducing new sounds without blocking the sounds from your environment.



您可以將全息圖放在世界或標記中A hologram can be placed in the world or tag along with you

當您有特定的全息圖位置時,可以將它精確地 在世界各地。When you have a particular location for a hologram, you can place it precisely at that point in the world. 當您四處解說時,會根據您的世界來看,全像是穩定的。As you walk around, the hologram appears stable based on the world around you. 如果您使用 空間錨點 來釘選物件,則當您稍後返回時,系統甚至可以記得您離開該物件的位置。If you use a spatial anchor to pin the object, the system can even remember where you left it when you come back later.

有些全息圖案會改為遵循使用者,無論使用者在何處都能自行定位。Some holograms follow the user instead, positioning themselves based on the user no matter where they walk. 您甚至可以選擇將一段時間帶到一段時間,然後在到達另一個房間之後,將它放在牆上。You may even choose to bring a hologram with you for a while and then place it on the wall once you get to another room.

最佳作法Best practices

  • 在某些案例中,您可能會要求在整個體驗中,全像全像的全像是,Some scenarios may demand that holograms remain easily discoverable or visible throughout the experience. 這種定位有兩種高階方法。There are two high-level approaches to this kind of positioning. 讓我們將其稱為「 顯示鎖定 」和「 主體鎖定」。Let's call them "display-locked" and "body-locked".
    • 顯示鎖定的內容會 positionally 「鎖定」至裝置顯示。Display-locked content is positionally "locked" to the device display. 這種類型的內容很難處理,因為有許多原因,包括非自然的「clingyness」,讓許多使用者感到挫折,並且想要「搖動」。This type of content is tricky for several reasons, including an unnatural feeling of "clingyness" that makes many users frustrated and wanting to "shake it off." 一般情況下,許多設計師都發現更適合用來避免顯示鎖定的內容。In general, many designers have found it better to avoid display-locking content.
    • 主體鎖定的方法遠 forgivable。The body-locked approach is far more forgivable. 本文-鎖定是指您在3d 空間中 tether 使用者的內文或注視向量。Body-locking is when you tether a hologram to the user's body or gaze vector in 3d space. 許多經驗都採用了內文鎖定行為,其中的全像是使用者注視的,這可讓使用者旋轉其內文,並在空間中移動,而不會遺失全像影像。Many experiences have adopted a body-locking behavior where the hologram "follows" the users gaze, which allows the user to rotate their body and move through space without losing the hologram. 合併延遲有助於讓全息圖移動感覺更自然。Incorporating a delay helps the hologram movement feel more natural. 比方說,Windows 全像是 Windows 全像的時候,在使用者的外觀鎖定之後,會在使用者看起來像是一種非常有彈性的延遲,在使用者關閉其前端時使用變化。For example, some core UI of the Windows Holographic OS uses a variation on body-locking that follows the user's gaze with a gentle, elastic-like delay while the user turns their head.
  • 將全像觀賞距離的全像是大約是1-2 的計量離 head。Place the hologram at a comfortable viewing distance typically about 1-2 meters away from the head.
  • 針對必須持續在全像全像框架中的元素提供漂移量,或考慮在使用者變更其觀點時,將內容以動畫顯示到顯示器的一端。Provide a drift amount for elements that must be continually in the holographic frame, or consider animating your content to one side of the display when the user changes their point of view.

將全像全區放在最理想的區域,介於 1.25 m 和 5 m 之間Place holograms in the optimal zone - between 1.25 m and 5 m

這兩個計量最適合,而且體驗將會降低從1計量取得的更接近程度。Two meters is the most optimal, and the experience will degrade the closer you get from 1 meter. 在距離超過1個計量的距離中,定期移至深度的全像是很可能會造成問題,而不是固定的全像投影。At distances nearer than 1 meter, holograms that regularly move in depth are more likely to be problematic than stationary holograms. 當內容太近時,請考慮以適當的方式裁剪或淡化內容,如此您就不會讓使用者進入未預期的體驗。Consider gracefully clipping or fading out your content when it gets too close so you don't jar the user into an unexpected experience.

從使用者處放置全像影像的最佳距離。



與您和您的世界互動的全像影像A hologram interacts with you and your world

全像全像光和音效;它們也是您世界上的有效部分。Holograms aren't only about light and sound; they're also an active part of your world. 以您手中的手中看看您的手中的手,然後您就可以開始使用全像投影。Gaze at a hologram and gesture with your hand, and a hologram can start to follow you. 提供聲音命令給全像影像,並可回復。Give a voice command to a hologram, and it can reply.

全像是可讓您無法在別處進行個人互動。Holograms enable personal interactions that aren't possible elsewhere. 由於 HoloLens 知道世界的所在位置,因此當您四處移動空間時,全像全像的字元可以直接在眼睛中看到。Because the HoloLens knows where it is in the world, a holographic character can look you directly in the eyes as you walk around the room.

全息圖也可以與您的環境互動。A hologram can also interact with your surroundings. 例如,您可以將全息的彈跳球放在資料表上方。For example, you can place a holographic bouncing ball above a table. 然後,利用點 一下,觀賞球彈,然後在到達表格時音效。Then, with an air tap, watch the ball bounce, and make sound when it hits the table.

實際的物件也可以 pixels occluded 全像影像。Holograms can also be occluded by real-world objects. 例如,全像攝影的字元可能會讓您看不到幕後的大門。For example, a holographic character might walk through a door and behind a wall, out of your sight.

整合全像影像和真實世界的秘訣Tips for integrating holograms and the real world

  • 對齊 gravitational 規則可讓您更輕鬆地與可信相關的影像。Aligning to gravitational rules makes holograms easier to relate to and more believable. 例如:將全像狗放在地面上 & 花瓶在資料表上,而不是讓它們浮在空間中。for example: Place a holographic dog on the ground & a vase on the table rather than have them floating in space.
  • 許多設計人員發現,他們可以藉由在桌上的表面上建立「負陰影」來整合更可信的全像投影。Many designers have found that they can integrate more believable holograms by creating a "negative shadow" on the surface that the hologram is sitting on. 若要這麼做,您可以在全像是建立全像影像,然後從發光減去「陰影」。They do this by creating a soft glow on the ground around the hologram and then subtracting the "shadow" from the glow. 軟性發光與真實世界的光線整合,其使用陰影來地面環境中的全像影像。The soft glow integrates with the light from the real world, which uses the shadow to ground the hologram in the environment.
