Patent number: 11715331Abstract: A disclosed computer-implemented method may include directing a display device included in a head-mounted display worn by a user to illuminate, via a projection of a line at an illumination time, a portion of a cornea of the user. The method may further include detecting, via an image sensor at a detection time, a portion of the projection of the line reflected by the portion of the cornea of the user and identifying a distortion of the projection of the line reflected by the portion of the cornea of the user. The method may also include determining a shape of the cornea of the user based on the illumination time, the detection time, and the distortion of the projection of the line reflected by the portion of the cornea. Various other methods, systems, apparatuses, and computer-readable media are also disclosed.Type: GrantFiled: April 1, 2021Date of Patent: August 1, 2023Assignee: Meta Platforms Technologies, LLCInventors: Alexander Jobe Fix, Dmitri Model, Mohammadhossein Daraeihajitooei, Javier San Agustin Lopez, Mohamed Hegazy, Scott Robert Ramsby, Sebastian Sztuk

Patent number: 11669160Abstract: Various aspects of the subject technology relate to prediction of eye movements of a user of a head-mountable display device. Predictive foveated display systems and methods, using the predicted eye movements are also disclosed. Predictive variable focus display systems and methods using the predicted eye movements are also disclosed. Predicting eye movements may include predicting a future gaze location and/or predicting a future vergence plane for the user's eyes, based on the current motion of one or both of the user's eyes. The predicted gaze location may be used to pre-render a foveated display image frame with a high-resolution region at the predicted gaze location. The predicted vergence plane may be used to modify an image plane of a display assembly to mitigate or avoid a vergence/accommodation conflict for the user.Type: GrantFiled: September 20, 2021Date of Patent: June 6, 2023Assignee: Meta Platforms Technologies, LLCInventors: Sebastian Sztuk, Javier San Agustin Lopez, Steven Paul Lansel

Patent number: 10984756Abstract: A display system divides a screen into regions and applies a different set of rendering/encoding parameters to each region. The system applies a first set of parameters to a first region that is being viewed by a fovea of an eye of a user. The system may also apply a second set of parameters to a second region that is being viewed by a parafovea of the eye, and apply a third set of parameters to a third region that is being viewed by the area of the eye outside of the parafovea. The first set of parameters are selected to yield relatively high image quality, while the second set of parameters are yield intermediate quality, and the third set of parameters yield lower quality. As a result, the second region and the third region can be rendered, encoded, and transmitted with less computing power and less bandwidth.Type: GrantFiled: June 26, 2019Date of Patent: April 20, 2021Assignee: Facebook Technologies, LLCInventors: Martin Henrik Tall, Javier San Agustin Lopez, Rasmus Dahl
