- | ==Observable state== | + | |
- | Known at all times, usually internal - eg. battery state. | + | |

- | ==Partially observable state== | + | |
- | Through a sensor, along with noise eg: camera image pixels | + | |

- | ==Hidden state== | + | |
- | What you are actually interested in, in the real world - eg: position of user's head. | + | |
- | Can't be directly known, must be indirectly inferred from (maybe multiple) sensors. See [[sensor fusion]]. | + | |
