摘要： The system displays an image portraying a virtual space as viewed by a virtual camera at a first location on a spatially navigable camera surface within the virtual space. A user begins a drag operation. Based on the dragging, the virtual camera is spatially translated from the first location on the spatially navigable region to a second location on the spatially navigable region. The orientation of the virtual camera at the second location may be automatically set to either point towards the pre-defined look-at point or to point in a direction normal to the spatially navigable region at the second location. The system then displays an image portraying the virtual space in accordance with the location and orientation of the virtual camera at the second location in the spatially navigable camera surface. While the drag operation continues, the system determines that further translating the virtual camera would place the virtual camera beyond the spatially navigable region. In response, the system begins displaying a transition, which may be an interpolated animation of the virtual camera, an animation semi-transparently blended with a slate, a pre-authored animation of the virtual camera, or other visual effect. While further continuing to drag, and based on the same, the system either advances display of the transition, reverses display of the transition, or otherwise temporally controls the display of the transition.
摘要翻译：该系统显示在虚拟空间内的空间可导航的相机表面上的第一位置处的虚拟照相机所观察到的描绘虚拟空间的图像。用户开始拖动操作。基于拖动，虚拟相机在空间上可导航区域上的第一位置被空间转换到空间可导航区域上的第二位置。可以将第二位置处的虚拟相机的方向自动设置为指向预定义的观看点或指向与第二位置处的空间可导航区域垂直的方向。然后，系统根据虚拟相机在空间可导航相机表面的第二位置处的位置和方位来显示描绘虚拟空间的图像。当拖动操作继续时，系统确定进一步翻译虚拟相机将使虚拟相机超出空间可通航区域。作为响应，系统开始显示转换，其可以是虚拟相机的内插动画，与平板半透明混合的动画，虚拟相机的预创作动画或其他视觉效果。在进一步继续拖动的同时，该系统可以提前显示转换，反转转换的显示，或以其他方式临时控制转换的显示。

摘要： The present invention is a system that creates a volumetric display and a user controllable volumetric pointer within the volumetric display. The user can point by aiming a beam which is vector, planar or tangent based, positioning a device in three-dimensions in association with the display, touching a digitizing surface of the display enclosure or otherwise inputting position coordinates. The cursor can take a number of different forms including a ray, a point, a volume and a plane. The ray can include a ring, a bead, a segmented wand, a cone and a cylinder. The user designates an input position and the system maps the input position to a 3D cursor position within the volumetric display. The system also determines whether any object has been designated by the cursor by determining whether the object is within a region of influence of the cursor. The system also performs any function activated in association with the designation.

摘要： The present invention is a system that allows a number of 3D volumetric display or output configurations, such as dome, cubical and cylindrical volumetric displays, to interact with a number of different input configurations, such as a three-dimensional position sensing system having a volume sensing field, a planar position sensing system having a digitizing tablet, and a non-planar position sensing system having a sensing grid formed on a dome. The user interacts via the input configurations, such as by moving a digitizing stylus on the sensing grid formed on the dome enclosure surface. This interaction affects the content of the volumetric display by mapping positions and corresponding vectors of the stylus to a moving cursor within the 3D display space of the volumetric display that is offset from a tip of the stylus along the vector.

摘要： A system that provides a bimanual user interface in which an input device is provided for each of the users hands, a left hand (LH) device and a right hand (RH) device. The input devices are used in conjunction with a large format, upright, human scale display at which the user can stand and upon which the input devices are moved. The positions of the input devices on the display are marked by displayed cursors. The system detects the position of the input devices relative to the display and draws a vector corresponding to unfastened tape between positions of cursors of the corresponding input devices and pointing from the LH device to the RH device. By changing the state of the LH input device the unfastened tape can be fastened or pinned along the vector as the user moves the LH device toward the RH device. By changing the state of the RH device, the tape can be unfastened by moving the LH device away from the RH device. Straight lines are drawn by holding the RH fixed while the LH pins the tape. Curves are drawn by moving the RH device while the LH device pins the tape. The switch between straight and curved lines occurs without an explicit mode switch simply by keeping the RH device fixed or moving it. The radius of the curvature of curved lines corresponds to the separation between the LH and RH devices.
摘要翻译：一种提供双手（LH）装置和右手（RH）装置）的双手用户界面的系统，其中为每个用户手，左手（LH）装置和右手（RH）装置提供输入装置。输入设备与大尺寸，直立的人体尺寸显示器结合使用，用户可以在该尺寸显示器上移动输入设备。显示器上的输入设备的位置由显示的光标标记。该系统相对于显示器检测输入装置的位置，并且在相应输入装置的光标位置和从LH装置指向RH装置的位置之间绘制与未松开带对应的矢量。通过改变LH输入设备的状态，当用户将LH设备朝向RH设备移动时，松开的胶带可以沿矢量被固定或固定。通过改变RH装置的状态，可以通过将LH装置移离RH装置来松开带子。当LH固定磁带时，通过保持RH固定来绘制直线。在LH设备插入磁带的同时移动RH设备来绘制曲线。直线和曲线之间的切换通过简单地通过保持RH装置固定或移动而没有明确的模式切换而发生。曲线曲率的半径对应于LH和RH装置之间的间隔。

摘要： The present invention is a system that manages a volumetric display using volume windows. The volume windows have the typical functions, such as minimize, resize, etc., which operate in a volume. When initiated by an application a volume window is assigned to the application in a volume window data structure. Application data produced by the application is assigned to the windows responsive to which applications are assigned to which windows in the volume window data structure. Input events are assigned to the windows responsive to whether they are spatial or non-spatial. Spatial events are assigned to the window surrounding the event or cursor where a policy resolves situations where more than one window surrounds the cursor. Non-spatial events are assigned to the active or working window.

摘要： The present invention is a system that allows a user to physically rotate a three-dimensional volumetric display enclosure with a corresponding rotation of the display contents. The rotation of the enclosure is sampled with an encoder and the display is virtually rotated by a computer maintaining the scene by an amount corresponding to the physical rotation before being rendered. This allows the user to remain in one position while viewing different parts of the displayed scene corresponding to different viewpoints. The display contents can be rotated in direct correspondence with the display enclosure or with a gain (positive or negative) that accelerates the rotation of the contents with respect to the physical rotation of the enclosure. Any display widgets in the scene, such as a virtual keyboard, can be maintained stationary with respect to the user while scene contents rotate by applying a negative rotational gain to the widgets. The rotation can also be controlled by a time value such that the rotation continues until a specified time is reached or expires.

摘要： A system that has a flexible tape input device with bend and twist sensors spaced along the tape and a curve generation system producing a virtual B-spline tape curve using the bend and twist information. A shape of the tape can be physically constrained to assist a user in obtaining and holding a desired shape. A world position sensor senses the real world position and orientation for the tape in world space and the virtual curve is placed in a scene responsive to the position and orientation. The curve at a desired location can be input into a virtual scene. The virtual curve can be used to create, control and edit 3D curves, surfaces and objects in real time. The tape can also act as a shape scanning device as well as a command input device.
