Generating accurate augmented reality objects in relation to a real-world surface via a digital writing device

A non-transitory computer readable storage medium comprising instructions thereon that, when executed by at least one processor, cause a computer system to:

• detect, by way of a pressure sensor of a writing device, an initial contact of the writing device with a real-world surface;
• determine, in response to the detected initial contact and by way of a locator element associated with the writing device, an initial location of the writing device;
• detect real-world movement of a tip of the writing device relative to the initial location by:
• tracking motion of a motion detector element located on the writing device, wherein the motion detector element comprises at least one of a reflective element operable to reflect a light within a range of light wavelengths or an emitter operable to project a trackable visual indicator onto the real-world surface;
• and
• determining, during the real-world movement, a position of the tip of the writing device relative to the motion detector element;
• and
• render, by way of an augmented reality device and based on the detected real-world movement of the tip of the writing device, an augmented reality object such that the augmented reality object appears to be drawn on the real-world surface.

A writing device for composing augmented reality objects for display by way of an augmented reality device based on tracking movement of the writing device on a real-world surface, the writing device comprising:

• a housing having a tip on a first end of the housing;
• a pressure sensor within the housing that, when triggered, indicates a pressure force applied to the tip;
• an inertial measurement unit within the housing, comprising at least one accelerometer, that detects at least one of:
• a location of the writing device or a tilt of the writing device;
• a locator element operable to indicate a location of the writing device, the locator element being affixed to the housing and comprising at least one of:
• an emitter that projects a visual indicator onto a writing surface or a reflective element that reflects a range of light wavelengths measurable by an augmented reality device;
• a reflective motion detector element operable to indicate real-world movement the a tip of the housing based on a position of the tip of the housing relative to the reflective motion detector element;
• and
• a transceiver element affixed to the housing that sends information associated with at least one of:
• the pressure sensor, the inertial measurement unit, the locator element, or the reflective motion detector element.
