摘要： A computer receives animated images together with a real world image. The computer then superimposes the animated images onto the real world image. The result is a combined animated/real image which forms the virtual world. The combined image is capable of moving as the user's head moves. Thus, complicated virtual worlds may be created without the programming complexity which would result if the entire image were animated.

摘要： A head-coupled display device for use in presenting electronically generated visual images to a viewer. The device includes a headpiece worn by a viewer, and an image display screen mounted in the headpiece for presenting electronically generated images. A fresnel lens is positioned adjacent the screen for focusing images from the screen at a selected position for viewing as a virtual image. The lens has a set of concentric converging rings whose surface curvatures act to minimize rectilinear distortion of the virtual images perceived by the viewer over the entire field of view of the image.

摘要： A computer display displays a data flow network as a plurality of interconnected units. An interactive program allows the appearance of the plurality of interconnected units to be changed. The data flow network then is automatically altered to correspond with the visual changes. The interconnected units of the data flow network represent inputs, functions and outputs of the data flow network. Inputs represent control signals to manipulate the data flow network, functions modify the value of inputs according to the type of the function unit and outputs represent the x, y or z value of a point in a three-dimensional coordinate system of the virtual world.

摘要： A distributed animation comprising a plurality of processors wherein each processor is responsible for rendering only a portion of the entire image. After the plurality of processors compute their respective images, the image data is communicated to a buffer. The buffer also receives image data from other sources. The buffer combines the image data from all sources into a single image frame which is then stored in a frame buffer. The buffer comprises a plurality of buffer elements, each buffer element being associated with a single graphics element (processor or video source). Each buffer element includes an input terminal for receiving pixel data from its corresponding graphics element, an output terminal for outputting pixel data, and a second input terminal for receiving pixel data from the output terminal of a previous buffer element. The pixel data typically includes a Z value which provides the depth location in the image of the object represented by that pixel. The Z value of the pixel received on the first input terminal is compared to the Z value of the pixel received on the second input terminal, and the multiplexer outputs the pixel value that is "closer" in the image.

摘要： A radiation source directs radiation toward a radiation sensor in such a way that the intensity of radiation sensed by the radiation sensor alternates in a periodic manner as the radiation source moves radially relative to the radiation sensor. The radiation sensor generates either a "1" or a "0" depending upon whether the intensity of the radiation sensed by the radiation sensor is above or below a particular reference value. Thus, the angular position of the radiation source relative to the radiation sensor is indicated by an alternating series of "1"s and "0"s. A multi-bit binary value which indicates the absolute position of the radiation source relative to the radiation sensor can be generated. In this case, a band of radiation is directed toward the radiation sensor. The radiation band is separated into a plurality of portions, the intensity of each successive portion being twice the frequency of the preceding portion. Each portion of the radiation band impinges upon a corresponding sensor. The signal generated by each sensor element is thus one bit of a multi-bit binary value which varies as the radiation source moves radially relative to the radiation sensor.
摘要翻译：辐射源以辐射传感器的方式将辐射引向辐射传感器，使得当辐射源相对于辐射传感器径向地移动时，辐射传感器感测到的辐射强度以周期性方式交替。辐射传感器根据辐射传感器感测到的辐射强度是高于还是低于特定参考值，产生“1”或“0”。因此，辐射源相对于辐射传感器的角度位置由“1”和“0”的交替系列表示。可以产生指示辐射源相对于辐射传感器的绝对位置的多位二进制值。在这种情况下，辐射带指向辐射传感器。辐射带被分成多个部分，每个连续部分的强度是前一部分的频率的两倍。辐射带的每个部分照射在相应的传感器上。因此，由每个传感器元件产生的信号是随着辐射源相对于辐射传感器径向移动而变化的多位二进制值的一位。

摘要： Apparatus is disclosed for generating control signals for the manipulation of virtual objects in a computer system according to the gestures and positions of an operator's hand or other body part. The apparatus includes a glove worn on the hand which includes sensors for detecting the gestures of the hand, as well as hand position sensing means coupled to the glove and to the computer system for detecting the position of the hand with respect to the system. The computer system includes circuitry connected to receive the gesture signals and the hand position signals for generating control signals in response thereto. Typically, the control signals are used to manipulate a graphical representation of the operator's hand which is displayed on a monitor coupled to the computer system, and the graphical representations of the operator's hand manipulates virtual objects or tools also displayed by the computer.

摘要： A computer model of a virtual environment is continuously modified by input from various participants. The virtual environment is displayed to the participants using sensory displays such as head-mounted visual and auditory displays which travel with the wearer and track the position and orientation of the wearer's head in space. Participants can look at each other within the virtual environment and see virtual body images of the other participants in a manner similar to the way that people in a physical environment see each other. Each participant can also look at his or her own virtual body in exactly the same manner that a person in a physical environment can look at his or her own real body. The participants may work on a common task together and view the results of each other's actions.
