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

Patent number: 10921896Abstract: An augmented reality (AR) device can access a library of applications or user interfaces (UIs) designed to control a set of devices. The AR device can determine which UI to present based on detection of a device to be controlled near the AR device. For example, a user wearing an AR device may look at a thermostat placed on a wall and a UI to control the thermostat may be presented to the user. The determination that the user is looking at the thermostat may be made by correlating the gaze tracking information of the user-facing camera with the location of the thermostat in an image captured by a world-facing camera. Determination of the location of the thermostat in the image can be performed using image recognition technology. The UI can be selected based on a database record pairing the UI with the thermostat.Type: GrantFiled: March 16, 2016Date of Patent: February 16, 2021Assignee: Facebook Technologies, LLCInventors: Javier San Agustin Lopez, Martin Henrik Tall, Rasmus Dahl, Jonas Priesum

Patent number: 10715824Abstract: Systems and methods for reducing, with minimal loss, optical sensor data to be conveyed to another system for processing. An eye tracking device, such as a head-mounted display (HMD), includes a sensor and circuitry. The sensor generates image data of an eye. The circuitry receives the image data, and assigns pixels of the image data to a feature region of the eye by comparing pixel values of the pixels to a threshold value. A feature region refers to an eye region of interest for eye tracking, such as a pupil or glint. The circuitry generates encoded image data by apply an encoding algorithm, such as a run-length encoding algorithm or contour encoding algorithm, to the image data for the pixels of the feature region. The circuitry transmits the encoded image data, having a smaller data size than the image data received from the sensor, for gaze contingent content rendering.Type: GrantFiled: March 16, 2017Date of Patent: July 14, 2020Assignee: Facebook Technologies, LLCInventors: Martin Henrik Tall, Sune Loje, Javier San Agustin Lopez

Patent number: 10013056Abstract: A user of a computing device may interact with and control objects and applications displayed on the computing device through the user's eye movement. Detected gaze locations are correlated with actions performed by the user and compared with typical gaze locations for those actions. Based on differences between the detected and expected gaze locations, the eye tracking system can be recalibrated. An area around a gaze location encompassing a set of likely active locations can be enlarged, effectively prompting the user to interact with the desired active location again. The enlarging of the area serves to separate the active locations on the screen, reducing the probability of interpreting the user's gaze incorrectly.Type: GrantFiled: October 31, 2017Date of Patent: July 3, 2018Assignee: Facebook, Inc.Inventors: Javier San Augustin Lopez, Martin Henrik Tall, Benjamin Antoine Georges Lefaudeux, Henrik Hegner Tomra Skovsgaard

Patent number: 9961258Abstract: Eye tracking technology may be used in a wide range of lighting conditions and with many different and varying light levels. In some embodiments, an eye tracking device may employ active illumination (e.g., in the form of infrared light-emitting diodes (LEDs)). However, employing active illumination may reduce the battery life of the device. Under some circumstances (e.g., in a dark environment), the light intensity may be excessive and could be reduced, thereby reducing energy consumption and extending the battery life of the device. An algorithm may be used to adjust the duration of light in eye tracking systems that employ active illumination.Type: GrantFiled: February 23, 2016Date of Patent: May 1, 2018Assignee: Facebook, Inc.Inventors: Martin Henrik Tall, Sebastian Sztuk, Javier San Agustin Lopez, Rasmus Dahl

Patent number: 9952666Abstract: Methods and systems to facilitate eye tracking control on mobile devices are provided. An image of a portion of a user is received at an eye tracking device, where the image includes reflections caused by light emitted on the user from one or more light sources located within the eye tracking device. One or more eye features associated with an eye of the user is detected using the reflections. Point of regard information is determined using the one or more eye features, where the point of regard information indicates a location on a display of a computing device coupled to the eye tracking device at which the user was looking when the image of the portion of the user was taken. The point of regard information is sent to an application capable of performing a subsequent operation using the point of regard information.Type: GrantFiled: March 8, 2017Date of Patent: April 24, 2018Assignee: Facebook, Inc.Inventors: Sebastian Sztuk, Martin Henrik Tall, Javier San Agustin Lopez
