Abstract
Embodiments are disclosed for a wearable device used as a digital pool attendant. In some embodiments, a method comprises: determining, with at least one processor of a wearable device, whether a user is swimming or not swimming based on sensor data; in accordance with the user not swimming, determining with the at least one processor and based on the sensor data, whether the user is showing regular or irregular behavior while swimming; and in accordance with the user showing irregular behavior, sending an alert message from the water over air to one or more other devices.
Claims19
A method comprising:
- training a first machine learning model to detect whether a swimmer is swimming or not swimming;
- training a second machine learning model to detect regular or irregular swimming behavior;
- obtaining sensor data from a wearable device attached to a user, the sensor data including inertial sensor data and pressure sensor data;
- determining that the user is submerged in water based on the pressure sensor data;
- predicting, with the first machine learning model, whether the user is swimming or not swimming based on the inertial sensor data;
- in accordance with the user being submerged and not swimming, predicting with the second machine learning model, whether the user is showing regular or irregular behavior while swimming based on the inertial sensor data;
- and
- in accordance with the user showing irregular behavior, sending an alert message from the water over air to one or more other devices.
5 more elements
A system comprising:
- at least one processor;
- a motion sensor configured to output motion data;
- a biosensor configured to output a biosignal;
- a pressure sensor configured to output pressure sensor data;
- a communication transmitter;
- memory storing instructions that when executed by the at least one processor cause the at least one processor to perform operations comprising:
- predicting, with a first machine learning model, whether a user is swimming or not swimming based on the motion data and biosignal;
- determining whether the user is submerged in water based on the pressure sensor data;
- in accordance with the user not swimming and being submerged in water, predicting, with a second machine learning model and based on the motion data and biosignal, whether the user is showing regular or irregular behavior while swimming;
- and
- in accordance with the user showing irregular behavior, sending, using the communication transmitter, an alert message from the water over air to one or more other devices.
8 more elements
A system comprising:
- a monitor and control station;
- and
- a plurality of wearable devices configured to:
- predict, with a first machine learning model, whether a user is swimming or not swimming based on inertial sensor data output by inertial sensors of the wearable devices;
- determine whether the user is submerged in water based on pressure sensor data output by pressure sensors of the wearable devices;
- in accordance with the user not swimming and being submerged in water, predict, with a second machine learning model and based on the inertial sensor data, whether the user is showing regular or irregular behavior while swimming;
- and
- in accordance with the user showing irregular behavior, sending an alert message to the monitor and control station.
