Techniques for enabling multiple mutually untrusted applications to concurrently generate augmented reality presentations

An augmented reality system, comprising:

• at least one environmental sensor device;
• at least one motion sensor device;
• at least one presentation device;
• and
• an augmented reality platform device communicatively coupled to the at least one environmental sensor device, the at least one motion sensor device, and the at least one presentation device;
• wherein the augmented reality platform device includes at least one processor and a non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by the at least one processor, cause the augmented reality system to perform actions for presenting augmented-reality annotations of real-world objects, the actions comprising:
• detecting, by the augmented reality system, a real-world object
• creating, by an operating system of the augmented reality system, a software object that represents the real-world object;
• receiving, by the operating system, a first request from a first application to present a first virtual object, the first request referencing the software object;
• determining, by the operating system, a first location for the first virtual object, wherein the first location is associated with the real-world object;
• and
• presenting, by the augmented reality system, the first virtual object at the first location.

A computer-implemented method of presenting augmented-reality annotations of real-world objects, the method comprising:

• receiving, by an augmented reality system, a reservation from a first application, wherein the reservation specifies a location reserved by the first application;
• receiving, by the augmented reality system, a request from a second application to generate a presentation;
• in response to determining that the presentation would not conflict with the reservation, generating, by the augmented reality system, the presentation;
• and
• in response to determining that the presentation would conflict with the reservation, deconflicting, by the augmented reality system, the presentation and the reservation.
