Patent number: 6999239Abstract: This invention has incorporated projective optics and phase conjugate material thus eliminating the requisite use of an external phase conjugate material to provide a see-through head mounted projective display. A key component of the invention is the use of optical imaging technology in combination with projective optics to make this revolutionary technology work. In previous head mounted projective displays the phase conjugate material had to be placed in the environment to display images, but in this invention one is not limited to the use of an external phase conjugate material but further extends its use to outdoor see-through augmented reality to produce images using the see-through head mounted projective display system. Furthermore, this invention extends the use of projective head mounted displays to clinical guided surgery, surgery medical, an outdoor augmented see-through virtual environment for military training and wearable computers.Type: GrantFiled: May 13, 2005Date of Patent: February 14, 2006Assignee: Research Foundation of the University of Central Florida, IncInventors: Ricardo F.

Patent number: 6804066Abstract: The projection lens system is designed for the head mounted projective display (HMPD) system to provide a wide field of view up to seventy degrees. The lens is optimized from a double-Gauss lens composed of two singlet lenses, one diffractive optical element (DOE) lens, one aspheric lens and a stop surface in the middle of the lens said lens has a focal length as low as approximately 23.9 mm whereby it has a field of view (FOV) of up to approximately 70 degrees and more. The lens can be combined with an additional field lens whereby the resulting lens combination provides improved image quality and/or field of view beyond approximately 70 degrees.Type: GrantFiled: November 1, 2002Date of Patent: October 12, 2004Assignee: University of Central FloridaInventors: Yonggang Ha, Jannick Rolland

Patent number: 6731434Abstract: A compact, ultra-light and high-performance projection optics lens assembly using Diffractive Optics Technology, plastic and glass optics, and Aspheric optics has been designed with only four elements. The lens may be included as is, or scaled to be included in all instruments using conventional Double-Gauss lens forms. The preferred lens is only 20 mm in diameter and 15 mm long has a weight of only 8 g. Thus, two lenses for head mounted stereo displays is only 16 g. Such a stereo display, known as a head-mounted projective display (HMPD), consists of a pair of miniature projection lenses, beam splitters, and miniature displays mounted on the helmet, and retro-reflective sheeting materials placed strategically in the environment.Type: GrantFiled: March 1, 2002Date of Patent: May 4, 2004Assignee: University of Central FloridaInventors: Hong Hua, Jannick Rolland

Patent number: 6708142Abstract: An algorithim for modeling the interaction of two colliding rigid objects. The algorithm allows the search of the optimal position and stabilization of two rigid objects when they are in contact due to a force pushing them against each other. The method does use mathematical integration and does not use any initial acceleration or speed conditioning for the results. The pushing direction can be changed at any time of the search for a correct specification. The moving solid is translated and rotated incrementally toward the equilibrium position and orientation in a non-natural way but leading to the same final attitude in a large range of initial conditions. One important novelty of this algorithm is the modeling of rotations involved for the moving object to go toward the natural position and orientation it should adopt. This can be done by the detection of torque during the search and the determination of the center of rotation in a quadratic time.Type: GrantFiled: January 12, 2000Date of Patent: March 16, 2004Assignee: University of Central FloridaInventors: Yoahan Baillot, Jannick Rolland

Patent number: 6433760Abstract: The eye-tracking system is based on the reflection of four light emitting diodes (LED)s at the cornea of user's eve. The LEDs emit infrared light at 900 nanometers and the virtual images formed behind the cornea as well as a near infrared image of the pupil are displayed on a charged couple device (CCD) sensor. The optical system used to display virtual environments is also used to conjugate the virtual images of the LEDs to the CCD sensor. This optimizes the integration of eyetracking system into the head mounted device (HMD). The four LEDs are laid out around the imaging (optical) system and their beam (rays) impinge directly on the eye by reflection on the hot mirror. Then the light reflected by the cornea is reflected again by the hot mirror, goes through the optical system and the cold mirror to be imaged on the sensor.Type: GrantFiled: December 23, 1999Date of Patent: August 13, 2002Assignee: University of Central FloridaInventors: Laurent Vaissie, Jannick Rolland
