Patent number: 10504287Abstract: A redundant tracking system comprising multiple redundant tracking sub-systems, enabling seamless transitions between such tracking sub-systems, provides a solution to this problem by merging multiple tracking approaches into a single tracking system. This system is able to combine tracking objects with six degrees of freedom (6DoF) and 3DoF through combining and transitioning between multiple tracking systems based on the availability of tracking indicia tracked by the tracking systems. Thus, as the indicia tracked by any one tracking system becomes unavailable, the redundant tracking system seamlessly switches between tracking in 6DoF and 3DoF thereby providing the user with an uninterrupted experience.Type: GrantFiled: October 24, 2017Date of Patent: December 10, 2019Assignee: Snap Inc.Inventors: Andrew James McPhee, Samuel Edward Hare, Peicheng Yu, Robert Cornelius Murphy, Dhritiman Sagar
