    • A computer apparatus includes a computer processing unit including a processor device for operating upon data and providing data for display. The apparatus further includes a handheld input/output display unit. The display unit includes a housing sized to be grasped by a user's hand. A computer display is located within the housing at a position to allow the user to view the computer display through an eyepiece. A display driver is used for presenting data from the processing unit on the computer display. Navigational input tools are integrated with the computer display in the housing and operatively connected to provide user input to the processing unit. The navigational input tools are positioned for operation by one or more fingers of the user's grasping hand. The computer processing unit may be integrated within the housing of the handheld input/output display unit. The navigational input tools may include a mouse having a force actuated pointer and at least one button, e.g., a single button mouse or a two button mouse, or may include a three button interface.
    • 计算机装置包括计算机处理单元,其包括用于对数据进行操作并提供用于显示的数据的处理器装置。 该装置还包括手持输入/输出显示单元。 显示单元包括尺寸被用户的手掌握的外壳。 计算机显示器位于壳体内的允许用户通过目镜观看计算机显示器的位置。 显示驱动器用于在计算机显示器上显示来自处理单元的数据。 导航输入工具与壳体中的计算机显示器集成,并且可操作地连接以向用户输入到处理单元。 导航输入工具被定位成由用户抓握的手的一个或多个手指操作。 计算机处理单元可以集成在手持式输入/输出显示单元的外壳内。 导航输入工具可以包括具有力致动指示器和至少一个按钮(例如单个按钮鼠标或两个按钮鼠标)的鼠标,或者可以包括三个按钮接口。

    • A multi-band high-speed videometric head tracking system having a gradient reflector array attached to a helmet on a person's head, ultraviolet light source emitting light which is reflected by the reflector array to a video camera which provides an image to a spot location estimator providing accurate locations of spots in the image representing the reflectors' reflecting light to image location accuracies within a pixel of the image. The location information from the spot location estimator goes to a track point 3-D location and helmet LOS estimator that provides location and orientation information to a Kalman Filter that accurately estimates and predicts the helmet position at faster rates than would be possible for a process that uses just the image-based measurements of the helmet.

    • A head mounted display includes a head suspension apparatus and a display coupled thereto. In a stationary state, the display is maintained in a desired position relative to the head suspension apparatus. Further, in a release state, the display is always freely movable both vertically and horizontally relative to the head suspension apparatus. In addition, the display may also always be freely rotatable about an axis of the display as well as vertically and horizontally. The coupling of the display to the head suspension apparatus may be attained using a slide bar and hinge mechanism that forms a rigid triangular structure when the display is in the stationary state. Further, the head suspension apparatus may include an adjustable temporal support element for positioning about the circumference of a user's head and an adjustable crown support connected to the temporal support with the crown support including channels for allowing electrical connection lines to move freely therein.
    • 头戴显示器包括头悬挂装置和耦合到其上的显示器。 在静止状态下,显示器保持在相对于磁头悬挂装置的期望位置。 此外,在释放状态下,显示器总是能够相对于头部悬挂装置垂直和水平地自由移动。 此外,显示器也可以总是围绕显示器的轴线以及垂直和水平自由旋转。 可以使用当显示器处于静止状态时形成刚性三角形结构的滑动杆和铰链机构来实现显示器与头部悬挂装置的联接。 此外,头悬挂装置可以包括用于围绕使用者头部的圆周定位的可调节的时间支撑元件和连接到时间支撑件的可调节冠部支撑件,其中冠部支撑件包括用于允许电连接线路在其中自由移动的通道。
