Techniques for calibrating localization parameters based on physically-identifiable landmarks, and systems, devices and methods of using such techniques

A method, comprising:

• obtaining, at a head-wearable device, sensor data about a localized physical area;
• determining, based on the sensor data, that a landmark-based-localization condition is satisfied
• in accordance with determining that the landmark-based-localization condition is satisfied, obtaining data about a physically-identifiable feature of a physical landmark detectable from the localized physical area;
• and
• based on (i) the data about the physically-identifiable feature of the physical landmark, and (ii) other data indicating a time when the data about the physically-identifiable feature of the physical landmark was obtained, determining an orientation and/or and a position of the head-wearable device within the localized physical area.

A head-wearable device, comprising one or more processors and memory comprising instructions that, when executed by the one or more processors, cause operations for:

• obtaining, at a head-wearable device, sensor data about a localized physical area;
• determining, based on the sensor data, that a landmark-based-localization condition is satisfied
• in accordance with determining that the landmark-based-localization condition is satisfied, obtaining data about a physically-identifiable feature of a physical landmark detectable from the localized physical area;
• and
• based on (i) the data about the physically-identifiable feature of the physical landmark, and (ii) other data indicating a time when the data about the physically-identifiable feature of the physical landmark was obtained, determining an orientation and/or and a position of the head-wearable device within the localized physical area.
