摘要

頭戴式顯示器產品從過往軍用頭盔到智慧型眼鏡等穿戴式裝置，引領出科技的進步帶來智慧生活的隨身化。然而，目前的智慧型眼鏡的產品大多有凸出一光棒於眼鏡前方，眼睛透過光棒的分光稜鏡觀看投射影像，除影響外觀和重量平衡之外，為避免光棒影響視線，多將光棒裝在視野的角落，使用者觀看其中影像或訊息時，眼睛必須往該角落轉動，此行為既不自然亦不符合人因視覺。
本研究針對此問題先使用光學模擬進行不同的頭戴式顯示所需要之合光元件進行體積的縮小，進一步拋棄傳統光棒的需求，使得頭戴式顯示產品外觀可以和一般眼鏡或者擋風鏡片一樣可透視，且影像可以視應用需求顯示在視野的中央或旁邊，應用範圍及使用便利性都可明顯提高，以符合消費者的期待。

Application of Head-Mounted Display (HMD) to wearable devices such as military helmets and smart glasses brings us a further step to smart life. However, most of existing smart glasses are equipped with projecting light bars in front of glasses. When people see projected images through splitting prism of the light bar, they may feel the appearance and balance of weights affected. In addition, most light bars are placed at the corner of field of view, enforcing users to rotate their eyes to the corner to read messages or images. This design is neither natural nor fits human visual behavior.
The research is aimed at resolving the problem by using optical simulators to simulate different combiner of HMD to narrow the volume of HMD. We hope to make HMD see-through like general glasses or windshield and reduce demand for traditional light bars. In addition, the image can be displayed next to or in the middle of the field of view depending on users’ needs. The enhancement of application scope and convenience can better satisfy customers’ anticipation.
