This is a detailed blog entry that explains the technological and manufacturing advancements that went into the North Star Project. Key questions inlcude:
What does hand tracking need to be like for an augmented reality headset? How fast does it need to be; do we need a hundred frames per second tracking or a thousand frames per second? How does the field of view impact the interaction paradigm? How do we interact with things when we only have the central field, or a wider field? At what point does physical interaction become commonplace? How does the comfort of the interactions themselves relate to the headset’s field of view?

Some techical decisions were:
  1. Inward-facing embedded cameras for automatic and precise alignment of the augmented image with the user’s eyes as well as eye and face tracking.
  2. Head mounted ambient light sensors for 360 degree lighting estimation.
  3. Directional speakers near the ears for discrete, localized audio feedback
  4. Electrochromatic coatings on the reflectors for electrically controllable variable transparency
  5. Micro-actuators that move the displays by fractions of a millimeter to allow for variable and dynamic depth of field based on eye convergence
