Disclosed herein are methods and systems for contextual adjustment of thresholds of user interestedness for triggering video recording. An embodiment takes the form of a method that includes identifying one or more current contextual attributes of a current context of a user. The method also includes setting a current value of a stored interestedness threshold based at least in part on the one or more identified current contextual attributes. The method also includes obtaining one or more current physiological measurements of the user. The method also includes deriving an interestedness score based at least in part on the one or more obtained current physiological measurements. The method also includes comparing the derived interestedness score to the current value of the stored interestedness threshold. The method also includes initiating video recording when the derived interestedness score exceeds the current value of the stored interestedness threshold.
