据RoadtoVR报道，Facebook首席执行官扎克伯格早在今年5月就谈及了“Quest Pro”，称这款头显可能包括面部和眼部追踪传感器，上个月Quest v32软件更新证实了扎克伯格的说法，Quest v32可支持Quest Pro以及面部及眼动追踪。
Reddit用户“Reggy04”在对Quest v32软件深入研究时发现了一些字符串，其中不仅包含了Quest Pro的名称，还包括了面部及跟动追踪功能，这意味着Quest Pro将采用大量传感器。
据说Quest Pro传感器可以改善目前的手势追踪功能，Quest Pro会估算用户手部大小及其移动方式，以完全支持用户手部的VR交互行为”。
不仅如此Quest Pro还内置了眼动追踪传感器，可用于注视点渲染和更智能的UI导航等多任务处理，以下这些字符则是关于眼动追踪的测试代码，与许多此类校准测试一样，用户需要注视虚拟对象，以便系统能够正确模拟眼动行为。
“\”FOLLOW THE TARGET WITH YOUR GAZE\””
“\”EYE CALIBRATION FAILED\””
“\”EYE MOVEMENT ESTIMATION COMPLETE\””
同时，v32更新还提到了面部跟踪，该追踪方式对社交VR交互很重要，通过以下测试代码，用户可以表达微笑、皱眉、愤怒露齿及惊讶等面部情绪。
“COPY THE DIFFERENT EXPRESSIONS\””
“\”SMILE NATURALLY UNTIL THE CALIBRATION IS COMPLETE. YOU MAY NEED TO HOLD THIS POSE FOR A FEW SECONDS.\””
“\”SHOW AN ANGRY EXPRESSION UNTIL THE CALIBRATION IS COMPLETE. YOU MAY NEED TO HOLD THIS POSE FOR A FEW SECONDS.\””
“\”FROWN NATURALLY UNTIL THE CALIBRATION IS COMPLETE. YOU MAY NEED TO HOLD THIS POSE FOR A FEW SECONDS.\””
“\”SHOW A SURPRISED EXPRESSION UNTIL THE CALIBRATION IS COMPLETE. YOU MAY NEED TO HOLD THIS POSE FOR A FEW SECONDS.\””
“\”FAILED TO CALIBRATE THE EXPRESSION. RETRYING…\””
“\”FACE MOVEMENT ESTIMATION COMPLETE\””
此外，Reggy04还发现了滑动镜头代码，这可能意味着Quest Pro包括某种形式的瞳孔间距（IPD）硬件调整，就像Oculus Rift一样，需要用户移动镜头以获得清晰的画面。
“\”SLIDE THE LENSES CLOSER TOGETHER OR FURTHER APART TO IMPROVE VISUAL CLARITY.\””
最后，Reggy04指出以下代码特别针对Quest Pro添加，旨在提供与 Rift S一样的深度镜头调整。
“\”PRESS AND HOLD THE DEPTH BUTTON AND MOVE THE HEADSET CLOSER OR FURTHER AWAY FROM YOUR FACE. THE LENSES SHOULD BE CLOSE TO YOUR EYES, BUT NOT CAUSE DISCOMFORT.\””
“\”ADJUST LENS DEPTH\””
“\”TURN THE WHEEL LEFT OR RIGHT TO ADJUST TIGHTNESS. THE FRONT PADDING SHOULD FIT DIRECTLY OVER YOUR FOREHEAD.\””
值得一提的是，Facebook Connect大会将于10月28日举行，届时我们或许能获得Quest Pro的进一步消息。
