This configuration enables the nose pad to be positioned in place, in other words, enables the visual recognition position fin the virtual-image display device to be adjusted in an easy and rapid manner by a method of rotating the pad L, R and retaining it at an appropriate position, thereby meeting various requirements made by unspecified individuals such as making adjustment according to the shape of their own nose. | 2019-08-01 |
20190235255 | SYSTEM, HEAD MOUNTED DEVICE (HMD) AND METHOD FOR ADJUSTING A POSITION OF AN HMD WORN BY A USER - The present disclosure provides embodiments of improved systems, head mounted devices (HMDs) and methods for adjusting a position of an HMD with respect to a user based on one or more measurements, which are specific to the user. One embodiment of the improved method includes receiving data from an eye tracking system of an HMD worn by a user, where the data is generated by the eye tracking system in response to the user gazing upon a virtual image plane of the HMD; using the received data to calculate a distance between the virtual image plane of the HMD and a pupil plane of the user; and adjusting a position of the HMD with respect to the user based on the calculated distance. | 2019-08-01 |
20190235256 | Anamorphic Illumination Optics For A MEMS Spatial Light Modulator - A system including two dimensional, microelectromechanical system (MEMS) based spatial light modulators and anamorphic optics for improved contrast is provided. Generally, the system comprises an array of modulators having a plurality of pixels along a longitudinal axis, each pixel comprising a plurality of modulators along a transverse axis of the array. An illumination source including a laser and anamorphic optics for focuses light from the laser onto the array, and imaging optics focus modulated light from the array onto an image plane. The anamorphic optics are configured to provide a transverse numerical aperture (NA) along the transverse axis of the array that is smaller than a diffraction angle of the modulated light reflected from the array along a transverse axis of the image plane, and a longitudinal NA along the longitudinal axis of the array that is greater than the transverse NA. Other embodiments are also provided. | 2019-08-01 |
