Providing positional information using beacon devices

An article of manufacture comprising a tangible medium, that is not a transitory propagating signal, encoding computer-readable instructions that, when applied to a computer system, instruct the computer system to perform a method comprising:

• receiving a plurality of signals at a first sensor of a hybrid reality (HR) system respectively from a plurality of beacon devices located along a path through a real-world environment, wherein the plurality of signals are invisible to a user of the HR system;
• determining positions of the plurality of beacon devices based on the signals;
• rendering an image of a plurality of virtual light beams respectively projecting from the positions of the plurality of beacon devices on a display of the HR system showing the path through the real-world environment in a field of view of the user;
• and
• modulating the plurality of virtual light beams based on a length of time that the respective plurality of signals have been received from the respective plurality of beacon devices.

A head-mounted display (HMD) comprising:

• a display;
• a structure, coupled to the display and adapted to position the display in a field of view (FOV) of a user;
• a sensor;
• and
• a processor, coupled to the display and the sensor, the processor configured to:
• receive a plurality of signal using the sensor, at the HMD respectively from a plurality of beacon devices located along a path through a real-world environment, wherein the plurality of signals are invisible to the user;
• determine positions of the plurality of beacon devices based on the signals;
• render an image of a plurality of virtual light beams respectively projecting from the positions of the plurality of beacon devices on the display showing the path through the real-world environment in the field of view of the user;
• and
• modulate the plurality of virtual light beams based on a length of time that the respective plurality of signals have been received from the respective plurality of beacon devices.
