摘要： Techniques for interacting with a first computing device based on gaze information are described. In an example, the first computing device captures a gaze direction of a first user of the first computing device by using an eye tracking device. The first computing device determines if the gaze direction of the first user is directed to a first display. Further, the first computing device receives information regarding if a gaze direction of a second user is directed to a second display. If the gaze direction of the first user is directed to the first display and the gaze direction of the second user is directed to the second display, the first computing device continuously updates content on the first display. If the gaze direction of the second user is not directed to the second display, the first computing device pauses the content on the first display.

摘要： Techniques for interacting with a first computing device based on gaze information are described. In an example, the first computing device captures a gaze direction of a first user of the first computing device by using an eye tracking device. The first computing device displays a representation of a second user on a display of the first computing device. Further, the first computing device receives from the first user, communication data generated by an input device. The first computing device determines if the gaze direction of the first user is directed to the representation of the second user. If the gaze direction of the first user is directed to the representation of the second user, the first computing device transmits the communication data to a second computing device of the second user.

摘要： Disclosed is a method for switching user input modality of a displaying device displaying an interactable region. The displaying device is in communication with a first input modality and a second input modality. The first input modality is an eye tracker configured to determine gaze data of a user and the second input modality is an input modality other than an eye tracker configured to determine a pointing ray. The first input modality is selected as the input modality of the displaying device. The method comprises determining whether the pointing ray of the second input modality is intersecting with the interactable region. The method further comprises, based on the determining switching the input modality of the displaying device to the second input modality when the pointing ray of the second input modality is intersecting with the interactable region.

摘要： An augmented reality, virtual reality, or other wearable apparatus comprises an eye tracking device comprising an image sensor, a lens, and one or more processors. In some embodiments, the lens comprises a marker, and the one or more processors are configured to receive an image from the image sensor, wherein the image shows the marker, determine a distance from the image sensor to the marker based on the image, and change a calibration parameter of an eye tracking algorithm based on the distance. In some embodiments, the one or more processors are configured to receive image data from the image sensor, wherein the image data corresponds to an image as observed through the lens, determine a level or pattern of pincushion distortion in the image based on the image data, and change a calibration parameter of an eye tracking algorithm based on the level or the pattern of pincushion distortion.
