Virtual object display interface between a wearable device and a mobile device

A system for displaying a virtual object comprising:

• a wearable device comprising a processor, a memory, and a display characterized by a field of view;
• a mobile device comprising a mobile camera;
• programming in the memory, wherein execution of the programming by the processor configures the wearable device to perform functions, including functions to:
• capture frames of video data with the mobile camera, wherein the mobile device is in motion along a course relative to a three-dimensional coordinate system;
• estimate a wearable device position relative to the three-dimensional coordinate system;
• calculate a virtual path based on the course traversed by the mobile device, wherein at least a portion of the virtual path is located outside the field of view;
• and
• present on the display a virtual object along the virtual path as an overlay relative to the mobile device and in accordance with the wearable device position.

A non-transitory computer-readable medium storing program code which, when executed, is operative to cause an electronic processor to perform the steps of:

• capturing frames of video data with a mobile camera coupled to a mobile device in motion along a course relative to a three-dimensional coordinate system;
• estimating a wearable device position relative to the three-dimensional coordinate system, the wearable device comprising the electronic processor and a semi-transparent display characterized by a field of view;
• calculating a virtual path based on the course traversed by the mobile device, wherein at least a portion of the virtual path is located outside the field of view;
• and
• presenting on the display a virtual object along the virtual path as an overlay relative to the mobile device and in accordance with the wearable device position.
