Abstract: Wearable devices using “legacy” sensors such as proximity sensors or infrared sensors suffer from false positives when, such as when they are placed in a hand, but not inserted on the user's body or on or into the user's ear. Embedding a PPG module or PPG sensor into the wearable device allows for the PPG module to act as a secondary check for the presence of a user wearing the wearable device. In some examples, the PPG module can be used as a sole sensor for the presence or absence of a human user. In other examples, a PPG module can be used to perform a secondary action after the “legacy” sensor performs a first action. For example, the first action can be connecting to a user device while the second action can be opening an application or playing music.
