Sometimes adding an extra piece of information makes everything click.
- Sometimes adding an extra piece of information makes everything click.
- Before, everything felt increasingly uncertain as you added more information to the pile.
- Then you add one specific piece and suddenly everything clicks into brilliant clarity.
- Paradigm-shifting observations have this characteristic.
- Another example is when you discover the hidden dimension that makes all of the previous incoherence suddenly be explainable.
- The world of SLAM gives a nice mental model with loop closing.[f]
- SLAM means Simultaneous Localization and Mapping.
- It's at the heart of any Augmented Reality flow.
- As you get more observations from the camera, you update your estimate of both the device's position in space, and the configuration of the environment.
- Naturally, drift happens and as you go for longer and your dead reckoning gets increasingly tenuous.
- Then, you notice that two spots are the same location, and you "loop close."
- Now, all of the intermediate observations can be snapped into the precise place, all at once.[g]
