Abstract: A surgical simulator provides both visual and tactile feedback in order to realistically portray an actual surgical procedure. The visual feedback is provided through an SGI graphics computer which drives a monitor to display two images of an eye at slightly different perspectives. A set of optics, which preferably mimics an actual surgical microscope, combines the two images to form a stereo image of the eye. An instrument for simulating a surgical tool is connected through three sets of levers and hinges to three servo-motors which collectively generate a resistive force along any direction. The forces provided to the instrument are modeled after forces measured during an actual procedure and therefore accurately simulate the feel of a surgical procedure. The position and orientation of the instrument is transmitted to the SGI graphics computer which manipulates the eye based upon the position and motion of the instrument and updates the image of the eye to display a manipulated eye.

Abstract: A motion-base ride simulator includes a passenger cabin which is carried by a plurality of actuators within a limited operating envelope. During operation of the ride the movements of the passenger cabin simulate G-forces associated with an audio-visual presentation to the passengers within the cabin.

In order to facilitate one or both of passenger ingress and egress of the cabin, the motion base is so associated with a stationary passenger platform that the passenger cabin may be moved to a passenger access position immediately adjacent to but not touching an adjacent edge of this platform. In this passenger access position of the cabin passengers may enter into or leave from the passenger cabin without use of a movable passenger platform.

Abstract: One embodiment of an autostart driver in the host device detects insertion of a storage media into a peripheral, searches for a file of a predetermined name in the storage media and automatically starts an application listed in instructions in the file.

Abstract: A method of identifying strengths and weaknesses in a student's ability to use their sensory channels which integrates five basic processes into a series of testing procedures. First, the nature of the test is specified, either by a teacher or by a pre-programmed default stored in the memory of a computer. Second, test material suitable for use with a test of the specified nature is identified and extracted from the memory of the computer and then presented to the student using the outputs of the computer. The responses of the student through the inputs of the computer are then recorded and analyzed for patterns which are capable of being correlated with deficiencies in the sensory channels under test. Finally, procedures are recommended for remediating the deficiencies identified by analysis of the performance data.

Abstract: An apparatus and method for improving physical coordination and ability to react to moving and stationary objects is disclosed herein. A pair of voltage controlled liquid crystal lenses (14, 16) are mounted in a support frame (12) which is worn by a user in the same manner as conventional eyeglasses.
