Methods and systems of a handheld spatially aware mixed-reality projection platform

A computerized system for augmenting a physical space with projected media content using a handheld spatially aware mixed reality projection device comprising:

• a processor;
• a memory containing instructions that when executed on the processor, causes the processor to perform operations that:
• with a mapping application in the handheld spatially aware mixed-reality projection device, relocalize the handheld spatially aware mixed-reality projection device based on a virtual three-dimensional map of a physical environment, wherein the relocalizing generates pose information of the handheld spatially aware mixed-reality projection device in the physical environment with respect to the virtual three-dimensional map;
• share the set of three-dimensional pose information with a game engine application of the handheld spatially aware mixed-reality projection device;
• with the game engine application, placing the handheld spatially aware mixed-reality projection device in a set of equivalent virtual world coordinates and corresponding orientation of the handheld spatially aware mixed-reality projection device in the virtual three-dimensional map of the space;
• wherein the virtual three-dimensional map of the physical space is augmented with digital media content to create a virtual environment;
• detecting that the handheld spatially aware mixed-reality projection device is pointing at a physical structure that corresponds to an image target;
• and
• using a laser projector in the handheld spatially aware mixed-reality projection device, wherein the handheld spatially aware mixed-reality projection device creates a projection field, wherein the spatially mapped digital media content is revealed from the virtual environment overlaid onto the physical environment.
