Embodiment Construction

[0038] figure 1 An overview of a system 100 for monitoring a user is shown according to an exemplary embodiment. System 100 includes one or more motion sensors 102 , one or more scene sensors 104 , such as at least one camera 104 a and at least one microphone 104 b , compliance unit 106 , controller 108 , included in wearable device 1000 . Optionally, the system 100 further includes a position detection unit 112 , a timing unit 114 and an emergency unit 116 . In addition, the wearable device 1000 also includes a contact sensor 110 .

[0039] Various examples of movement sensors 102 include, but are not limited to, inertial sensors (such as accelerometers, gyroscopes, etc.) and pressure sensors.

[0040] Various examples of scene sensors 104 include, but are not limited to, cameras 104a, microphones 104b, and the like. The scene sensor 104 provides information about the user's scene, in particular environmental information. For example, a GPS sensor can provide information ...

Abstract

A system for monitoring a user comprising one or more movement sensors configured to be worn by the user, the one or more sensors being included in a wearable device; one or more contextual sensors configured for providing contextual information of the user; a compliance unit configured for determining a wearing compliance status of the user; the wearing compliance status being associated with the wearable device of the user; and a controller configured for monitoring the user based on the determined wearing compliance status, wherein based on the determined wearing compliance status, the controller is configured to operate the system either in a compliance mode or in a non- compliance mode, wherein in the compliance mode, the controller is configured to monitor the user based on one or more signals received from the one or more movement sensors; and wherein in the non-compliance mode, the controller is configured to monitor the user based on one or more signals received either from the combination of the one or more movement sensors and the one or more contextual sensors or from only the one or more contextual sensors.

Description

technical field [0001] The present invention relates to the field of monitoring users, in particular, the field of detecting falls of users. Background technique [0002] A Personal Emergency Response System (PERS) can improve the quality of life of seniors living on their own while providing peace of mind for their loved ones. These systems typically utilize body-worn devices such as wristbands or neck-worn pendants. During an emergency, the user presses a panic button on the device, which establishes a two-way call with the service provider's call center. [0003] Body-worn fall detection systems, such as wrist-based devices or pendants worn around the user's neck, typically employ inertial sensors, such as accelerometers and gyroscopes, to track the movement of the device user, and additionally incorporate pressure sensors to Detect altitude changes. Events are further classified / determined as falls or non-falls taking into account these signals and subsequent feature ...
