Patent number: 11917126Abstract: 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.Type: GrantFiled: February 24, 2023Date of Patent: February 27, 2024Assignee: Tobii ABInventors: Jonas Andersson, Anders Clausen, Richard Hainzl, Anders Kingbäck, Simon Olin, Mark Ryan, Daniel Tornéus, Björn Nutti, Torbjörn Sundberg, Catarina Tidbeck, Ralf Biedert, Niklas Blomqvist, Dennis Rådell, Robin Thunström

Patent number: 8792910Abstract: A method and service-related nodes for providing a deferred distance notification for at least two user devices. A Location-based gateway receives a request for a deferred distance notification for user devices, and sends a request to a Location enabler for the location of the user devices. The gateway receives location data from the Location enabler, and monitors the fulfillment of user device distance-related event criteria. When a user device distance-related event criterion is fulfilled, the gateway triggers the deferred distance notification, and sends the notification of the user device distance event to an application node. The application node sends a location request after which the Application node receives the notification. Distance notification can thus be provided to a user requesting a location-deferred service, such that the location of entire groups of users can be revealed to the requesting party.Type: GrantFiled: October 23, 2009Date of Patent: July 29, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Kermit Qiu, Bjorn Andersson, Vitomir Ilic, Johan Bolin, Ake Busin
