    Abstract: A parameter of a consumption item (fuel, life) consumed as a game progresses is calculated. When a setting of a game termination condition changes, a rate of change of the parameter of the consumption item is changed according to the change of the setting. The game termination condition is a condition relating to the number of laps on a course, a time limit of a game or a game quota. The rate of change of the parameter of the consumption item is increased as the number of laps on a course is reduced, as the time limit of a game is shortened, or as the game quota is reduced. When a value of the parameter of the consumption item becomes equal to zero as a game progresses, the movement or motion of an object is disabled. The parameter of the consumption item is changed from an initial value set by a player with the rate of change which has been specified based on the game termination condition set by the player.

    Abstract: This invention provides in a safe and effective manner the experience of observing potential collision obstacles or other hazard images to the human operator of an otherwise conventional vehicle, (such as an automobile or aircraft) moving in a normal manner in a natural environment (such as an outdoor test track). The invention incorporates in addition to the mobile vehicle, computer-based image generation devices, and position, velocity, acceleration, measurement instruments to enable the simulated visual hazard images, including operator perception of and response to those hazard images. Making the actual moving vehicle part of the simulated hazard encounter means the vestibular (motion) cues and visual cues of the natural environment are very realistic, while only the computer-generated hazard images imposed on the natural environment view are virtual.

    Abstract: Aircraft flight data collection is enhanced by changing the data sampling rate as a function of an operational condition of the aircraft, such as its flight phase. An algorithm is used to determine the flight phase. Then, the data is collected at a first sampling rate when the flight phase is one of a first set of flight phases and collected at a second sampling rate when the flight phase is one of a second set of flight phases. The second sampling rate is greater than the first sampling rate to maximize the data storage capacity of the system. Generally, the higher sampling rate is used with transient flight phases such as takeoff and thrust reverse.

  • Patent number: 6574352
    Abstract: A method for anticipation and tracking eye movement for head tracked projectors which divides a projection surface into spherical triangles and uses interpolating calibration values stored at each vertex of the triangle. A calibration map is used that contains information about the relationship between the user's head orientation and where they are looking with their eyes at each calibration point. The projection surface is divided into spherical triangles which are searched to find the triangle which contain the user's interpolated view point by performing a dot product test between the interpolated view point and the unit normal vectors inside the three planes that make up the sides of the spherical triangle extended back to the eye point. When a dot product test fails for any side of the triangle the pointer is followed to the adjacent triangle where the test starts over.

  • Patent number: 6552699
    Abstract: A projector system has an image display with at least two image display portions each displaying a respective image. At least two projection assemblies are provided, each associated with a respective image display portion. These projection assemblies each receive a respective image from the respective image display portion and project this image onto the projection screen. The projection assemblies each include a system for independently and selectively locating the projected image on the screen. The projection assembly includes a stationary mirror supported adjacent the image display portion receiving the image therefrom and reflecting said image outwardly from the image display to the movable mirror. Preferably, the stationary mirror has an upper end portion and a lower edge portion. The lower edge portion is adjacent the image display portion and the mirror extends obliquely upwardly therefrom.

  • Patent number: 6454419
    Abstract: An image of the display screen including an indicated position is captured, and a low resolution image is produced from the captured high resolution image. A low resolution pixel corresponding to the indicated position is found within the low resolution image, and the indicated position is then found within the captured image based on a unit area that is associated with the low resolution pixel corresponding to the indicated position.

  • Patent number: 6437759
    Abstract: A vehicle simulator having a projection system for projecting a generated scene and symbology onto a common viewing screen. Tracking apparatus is provided for providing position and/or angular orientation signals representative of the eye of a person viewing the projected scene and symbology. An image generation system is included for generating the scene and symbology for the projection system, such scene and symbology being generated as a function of the position and/or angular orientation signals provided by the tracking apparatus. Such symbology is representative of symbology produced by a head-up display. The image generation system generates the scene and symbology with characteristics which simulate vignetting and/or occulting effect characteristics of the head-up display.

  • Patent number: 6283758
    Abstract: A simulator system in which a visual display assembly is arranged to present an image to be viewed on a display surface and a viewing station is positioned in front of the display surface such that a person looking from a predetermined eyepoint defined within the viewing station can see the display surface through a viewing window defined by the viewing station. The viewing station is displaceable relative to the visual display assembly between first and second positions to adjust the position of the display surface relative to the viewing window when viewed from the eyepoint. During displacement of the viewing station between the two positions, the viewing station is rotated about the eyepoint. The actuator is arranged such that the rate of rotation of the viewing station increases with distance from the first and second positions to a maximum when the viewing station is in an intermediate position.

  • Patent number: 6224218
    Abstract: An off-axis backscreen visual display system having an increased vertical field of view (FOV) is disclosed. The lower edge of the backscreen member in the display system is contoured in accordance with the structure of the aircraft and the observer's point of view. The contouring of the lower edge of the backscreen increases the upward FOV coverage without changing the eyepoint/display relationship.

  • Patent number: 6224380
    Abstract: The portable and compact motion simulator (10) comprises of a platform (22), a support base (20), one powered and controlled extensible member (24), and a motion base controller (26). The simulator can be used like a seat cushion that can be placed on a chair or can be part of a chair. The platform (22) is driven by the said extensible member (24) via a motion base controller (26) to effect motion along the single degree-of-freedom in synchronization with audio and visual images. The said motion base controller (26) provides computing resources to operate and control the motion simulator (10), thereby eliminating the need for computing resources external to the motion simulator (10). A dynamics control means (40) optimizes the dynamic performance of the motion base in accordance with the weight of the patron (02). The portable and compact motion simulator (10) is designed to simulate motion for a patron playing an interactive computer game or participating in a virtual reality experience.
