Patent number: 10718942Abstract: An eye tracking system for a NED device includes sensors that are directed toward and angularly offset from a user's eyes in a manner that causes circular features (e.g., irises and/or pupils) of the user's eyes to appear elliptical within sensor planes that correspond to the individual sensors. The eye tracking system determines parameters associated with detected ellipses and then uses these parameters to generate 3D propagations from the detected ellipses back to the user's eyes. By analyzing these 3D propagations with respect to ocular rotation models that represent how the pupils and iris rotate about the center of the eye, the eye tracking system determines pupil orientation parameters that define physical characteristics of the user's eyes. The pupil orientation parameters may then be used to determine interpupillary distance and/or vergence of the user's visual axis that extend from the user's fovea.Type: GrantFiled: October 23, 2018Date of Patent: July 21, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Sergio Ortiz Egea, Venkata Satya Reghavendra Bulusu, Bernard C.

Patent number: 10718986Abstract: An object is to provide a display device that performs accurate display. A circuit is formed using a transistor that includes an oxide semiconductor and has a low off-state current. A precharge circuit or an inspection circuit is formed in addition to a pixel circuit. The off-state current is low because the oxide semiconductor is used. Thus, it is not likely that a signal or voltage is leaked in the precharge circuit or the inspection circuit to cause defective display. As a result, a display device that performs accurate display can be provided.Type: GrantFiled: May 29, 2018Date of Patent: July 21, 2020Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Hajime Kimura, Atsushi Umezaki
