Abstract
An oral treatment device includes an inertial measurement unit, IMU, operable to output signals dependent on movement of the oral treatment device. The oral treatment device includes a controller configured to receive signals from the IMU indicating movement of the oral treatment device relative to the oral cavity, and process the received signals using a trained classification algorithm to obtain classification data, the classification algorithm being configured to determine whether the oral treatment device is being moved according to a predetermined movement type. The controller is configured to control the oral treatment device to perform an action using the classification data.
Claims23
An oral treatment device for use in treating an oral cavity of a user, the oral treatment device comprising:
- an inertial measurement unit, IMU, operable to output signals dependent on movement of the oral treatment device;
- and
- a controller configured to:
- receive signals from the IMU indicating movement of the oral treatment device relative to the oral cavity of the user;
- process the received signals using a trained classification algorithm to obtain classification data, the classification algorithm being configured to determine whether the oral treatment device is being moved according to a predetermined movement type;
- and
- control the oral treatment device to perform an action using the classification data,
- wherein the controller is configured to retrain the classification algorithm using the received signals from the IMU, such that the retrained classification algorithm is configured to determine whether the oral treatment device is being moved according to a further movement type, different to the predetermined movement type.
A method of operating an oral treatment device for use in treating an oral cavity of a user, the oral treatment device comprising:
- an inertial measurement unit, IMU, operable to output signals dependent on movement of the oral treatment device;
- and
- a controller,
- the method comprising, at the controller:
- receiving signals from the IMU indicating movement of the oral treatment device relative to the oral cavity of the user;
- processing the received signals using a trained classification algorithm to obtain classification data, the classification algorithm being configured to determine whether the oral treatment device is being moved according to a predetermined movement type;
- controlling the oral treatment device to perform an action using the classification data;
- and
- retraining the classification algorithm using the received signals from the IMU to determine whether the oral treatment device is being moved according to a further movement type, different to the predetermined movement type.
A non-transitory computer-readable medium comprising computer-executable instructions which, when executed by a computerised device, cause the computerised device to perform a method of operating an oral treatment device for use in treating an oral cavity of a user, the oral treatment device comprising an inertial measurement unit, IMU, operable to output signals dependent on movement of the oral treatment device, the method comprising:
- receiving signals from the IMU indicating movement of the oral treatment device relative to the oral cavity of the user;
- processing the received signals using a trained classification algorithm to obtain classification data, the classification algorithm being configured to determine whether the oral treatment device is being moved according to a predetermined movement type;
- and
- controlling the oral treatment device to perform an action using the classification data;
- and
- retraining the classification algorithm using the received signals from the IMU to determine whether the oral treatment device is being moved according to a further movement type, different to the predetermined movement type.
