Meta 執行長Mark Elliot Zuckerberg 於2021年的Facebook Connect 會議上強調元宇宙(Metaverse)是下一個前線，並說出「從現在開始，我們將以元宇宙為優先，而不是Facebook」，預告未來發展主力將放在自家的頭戴式裝置Oculus上。與此同時，數位晶片相關公司的股票隨之大漲，有許多人都期待元宇宙實際生成的那天。
頭戴式裝置是元宇宙不可或缺的存在，使用者在戴上裝置後，便會有身臨其境的「沉浸式」體驗。但這類裝置有極大的致命缺點，在長時間使用後會有超越普通3C裝置的疲憊感，甚至會有頭暈、頭痛、噁心、想吐等症狀。此類裝置的發展超過20年，但VAC(Vergence Accommodation)仍然沒有一個客觀的評估標準。
本篇論文提出一種全新的頭戴式裝置評估系統，主要使用本實驗室開發的高動態範圍 Shack-Hartmann 波前檢測器，利用客製化超大邊長23mm正方形微透鏡陣列(MLA)以及大片幅波前檢測器進行量測工具，待測物使用中強光電提供之混合實鏡(MR)裝置，透過在上面顯示直徑為20 Pixel之白點，並利用程式控制改變光場位置以完成不同視場的量測。最後使用入射光角度回推成像位置，並取得光源的光強、像差等各種資訊。
量測系統為初步架構，未來仍有許多的改善空間，在科技進步下，能擁有更多不同的待測物，產生更多可參考數據，以期對頭戴式裝置建立一客觀且通用的評估標準。

Meta CEO Mark Elliot Zuckerberg emphasized at the Facebook Connect conference in 2021 that the Metaverse is the next frontier, and said that "from now on, we will prioritize the Metaverse, not Facebook,", the main force of future development will be on headset “Oculus”. At the same time, stocks of digital chip-related companies have soared, and people are looking forward to the day when the Metaverse actually takes shape.
Head-mounted devices are an indispensable existence in the Metaverse. After wearing the device, users will have an "immersive" experience. However, the device has a huge fatal disadvantage. After long-term use, it will feel more tired than ordinary 3C devices, and even have symptoms such as dizziness, headache, nausea, and vomiting. Such devices have been developed for more than 20 years, but there is still no objective evaluation criterion.
This paper proposes a new head-mounted device evaluation system, which mainly uses the high dynamic range Shack-Hartmann wavefront detector developed in our laboratory, and uses a customized super large 23mm square microlens array (MLA) and large format the wavefront detector is used as a measurement tool. The object to be measured uses the mixed Reality (MR) device provided by the medium-intensity photoelectricity. By displaying a white spot with a diameter of 20 pixels on it, and using program control to change the position of the light field to complete different views. Field measurement. Finally, use the angle of incident light to push back the imaging position, and obtain various information such as light intensity and aberration of the light source.
The measurement system is a preliminary structure, and there is still a lot of room for improvement in the future. With the advancement of science and technology, it can have more different objects to be measured, and generate more reference data, in order to establish an objective and general evaluation of head-mounted devices.
