Existing near-eye display designs struggle to balance between multiple trade-offs such as form factor, weight, computational requirements, and battery life. These design trade-offs are major obstacles on the path towards an all-day usable near-eye display. In this work, we address these trade-offs by, paradoxically, removing the display from near-eye displays. We present the beaming displays, a new type of near-eye display system that uses a projector and an all passive wearable headset. We modify an off-the-shelf projector with additional lenses. We install such a projector to the environment to beam images from a distance to a passive wearable headset. The beaming projection system tracks the current position of a wearable headset to project distortion-free images with correct perspectives. In our system, a wearable headset guides the beamed images to a user's retina, which are then perceived as an augmented scene within a user's field of view. In addition to providing the system design of the beaming display, we provide a physical prototype and show that the beaming display can provide resolutions as high as consumer-level near-eye displays. We also discuss the different aspects of the design space for our proposal.

喜气洋洋的显示器

现有的近眼显示器设计难以在多种权衡之间取得平衡，例如外形、重量、计算要求和电池寿命。这些设计权衡是实现全天可用近眼显示器的主要障碍。在这项工作中，我们通过从近眼显示器中移除显示器来解决这些权衡问题。我们展示了发光显示器，这是一种使用投影仪和全无源可穿戴耳机的新型近眼显示系统。我们用额外的镜头修改了现成的投影仪。我们将这样的投影仪安装到环境中，从远处将图像传输到无源可穿戴耳机。光束投影系统跟踪可穿戴耳机的当前位置，以正确的视角投射无失真的图像。在我们的系统中，可穿戴式耳机将传送的图像引导至用户的视网膜，然后在用户的视野内将其视为增强场景。除了提供光束显示器的系统设计外，我们还提供了一个物理原型，并展示了光束显示器可以提供与消费级近眼显示器一样高的分辨率。我们还讨论了我们提案的设计空间的不同方面。
