Wearable device for medication adherence monitoring

The wireless communication device configured to transmit data to an external device for inducing the external device including a camera to initiate taking a video, the wireless communication device comprising:

• a transceiver;
• a motion sensor;
• an ambient light sensor;
• a controller;
• a housing having an inner space where the transceiver, the motion sensor, the ambient light sensor, and the controller are placed;
• and
• an attachment region implemented outside of the housing, the wireless communication device configured to attach to an object containing medication through the attachment region;
• wherein a controller is configured to:
• transmit the data to the external device through the transceiver;
• obtain a motion value reflecting a movement of the object by using the motion sensor,
• obtain an ambient light value reflecting an ambient environment of the object by using the ambient light sensor, and
• provide activation data based on the motion value and the ambient light value, the activation data indicating the camera of the external device to be activated,
• wherein the controller is further configured to:
• determine whether the ambient light value is equal to or greater than an ambient light threshold value when the motion value is equal to or greater than a motion threshold value, and
• generate the activation data and provide the activation data to the external device when the ambient light value is equal to or greater than the ambient light threshold value, and
• wherein the controller does not generate the activation data when the ambient light value is less than the ambient light threshold value even though the motion value is equal to or greater than the motion threshold value.
