摘要： A visual display device is provided for delivering a generated image, preferably combinable with environment light, to the eye of a user. The device is lightweight and compact but yields a high quality image. In one embodiment, a shroud protects from stray light and holds optical elements in desired alignment. In one embodiment an image generator is masked by at least two masks to provide for a high quality image without waste. In one embodiment, a removably mounted shield or activatable device and convert the apparatus from a see-through device to an immersion device and back again. In one embodiment, the device can be comfortably mounted to the user's head while still allowing for use of conventional eyeglasses. A tracker for outputting an indication of the orientation, attitude and/or position of a head-mounted display (HMD) may be provided. The tracker can be configured so that it is incorporated in the HMD housing and/or can be easily decoupled from the HMD, so that the HMD can be used without the tracker (e.g. for watching movies). Preferably, decoupling involves unplugging a single electrical connector (such as a cable) and unfastening a mechanical connection (such as a strap). Preferably the tracker provides pass-through of signal to the HMD and, when the tracker is coupled to the HMD, only a single cable or other data link connects the HMD-tracker combination to the host computer. In one embodiment, the tracker uses magnetic sensors. In another embodiment, one or more inertial sensors, such as a rate gyro and/or accelerometers are used.
摘要翻译：提供了一种视觉显示装置，用于将生成的图像优选地与环境光组合到用户的眼睛。该设备重量轻且紧凑，但产生高质量的图像。在一个实施例中，护罩防止杂散光并且保持所需对准的光学元件。在一个实施例中，图像发生器被至少两个掩模掩蔽以提供高质量的图像而不浪费。在一个实施例中，可移除地安装的屏蔽或可激活装置并且将装置从透视装置转换成浸没装置并再次返回。在一个实施例中，该装置可以舒适地安装到用户的头部，同时仍然允许使用常规的眼镜。可以提供用于输出头戴式显示器（HMD）的取向，姿态和/或位置的指示的跟踪器。跟踪器可被配置成使得它被并入HMD壳体中和/或可以容易地与HMD分离，使得HMD可以在没有跟踪器的情况下使用（例如用于观看电影）。优选地，解耦包括拔掉单个电连接器（例如电缆）并松开机械连接（例如带）。优选地，跟踪器向HMD提供信号传递，并且当跟踪器耦合到HMD时，只有单个电缆或其它数据链路将HMD跟踪器组合连接到主计算机。在一个实施例中，跟踪器使用磁性传感器。在另一个实施例中，使用一个或多个惯性传感器，例如速率陀螺仪和/或加速度计。
