Publication number: 20240134184Abstract: An image display system includes an optical subsystem configured to emit a modulated light beam, and a scanning mirror for generating a reflected light beam that is scanned according to randomly selected or pseudo-randomly selected scan patterns to generate multiple image fields of a multiple interlaced scan image. A plurality of different scan patterns can be cycled through, randomly or pseudo-randomly selected, for the different image fields to reduce artifacts that may be observed while viewing a projected image.Type: ApplicationFiled: December 29, 2023Publication date: April 25, 2024Applicant: Magic Leap, Inc.Inventors: Lionel Ernest Edwin, Björn Nicolaas Servatius Vlaskamp, Samuel A.

Publication number: 20230333369Abstract: Optical systems and methods for operation thereof are disclosed. A delimited zone is defined as a function of distance from the optical system based on a VAC limit, the delimited zone having at least one distance threshold. A virtual distance of a virtual depth plane from the optical system at which a virtual object is to be displayed is determined. It is determined whether the virtual distance is outside the delimited zone by comparing the virtual distance to the at least one distance threshold. A collimated pixel beam associated with the virtual object is generated by a projector of the optical system. The collimated pixel beam is modified to generate a modified pixel beam if the virtual distance is outside the delimited zone. Modifying the collimated pixel beam includes converging the collimated pixel beam and/or reducing a diameter of the collimated pixel beam.Type: ApplicationFiled: June 23, 2023Publication date: October 19, 2023Applicant: Magic Leap, Inc.Inventors: Michael Anthony Klug, William Hudson Welch, Jason Schaefer, Björn Nicolaas Servatius Vlaskamp, Robert D.

Publication number: 20230099062Abstract: Augmented and virtual reality display systems increase viewer comfort by reducing viewer exposure to virtual content that causes undesirable accommodation-vergence mismatches (AVM). The display systems limit displaying content that exceeds an accommodation-vergence mismatch threshold, which may define a volume around the viewer. The volume may be subdivided into two or more zones, including an innermost loss-of-fusion zone (LoF) in which no content is displayed, and one or more outer AVM zones in which the displaying of content may be stopped, or clipped, under certain conditions. For example, content may be clipped if the viewer is verging within an AVM zone and if the content is displayed within the AVM zone for more than a threshold duration. A further possible condition for clipping content is that the user is verging on that content.Type: ApplicationFiled: December 8, 2022Publication date: March 30, 2023Inventors: Brian David Schwab, Randall E.

Publication number: 20200043362Abstract: There is provided an apparatus and method of operating the apparatus to guide a user in a long-term memory training session. One or more items are rendered to the user in the long-term memory training session (202). A request is initiated for the user to recall at least one rendered item that directly precedes the request (204). A memory strategy applied by the user to the long-term memory training session is determined based on a response received from the user to the request (206). When the memory strategy applied by the user to the long-term memory training session is determined to be a working memory strategy (208), an action is initiated to guide the user to apply a long-term memory strategy to the long-term memory training session (210).Type: ApplicationFiled: October 5, 2017Publication date: February 6, 2020Inventors: Björn Nicolaas Servatius VLASKAMP, Laura KLAMING
