Auto-notification sensor for adjusting of a wearable device

A wearable apparatus mountable on an arm of a user, the wearable apparatus comprising:

• a wearable device sensor communicatively connected to the wearable apparatus and directed toward a hand of the user, wherein the wearable device sensor collects environment data comprises a representation of at least a portion of a calibrating object having at least one calibrating dimension of a predetermined size and a target machine-readable code having a determinable size;
• at least one processor;
• and
• at least one memory including program code, the at least one memory and the program code configured to, with the at least one processor, cause the wearable apparatus to at least:
• receive environment data from the wearable device sensor;
• decode the target machine-readable code;
• determine a position of the wearable apparatus on the arm of the user based on a first size of the calibrating object and a second size of the target machine-readable code;
• and
• alert the user to adjust the position of the wearable apparatus based on the position of the wearable apparatus relative to the calibrating object.

A computer program product for alerting a user to adjust a wearable device, the computer program product comprising at least one non-transitory computer-readable storage medium storing program instructions that, when executed, cause the computer program product to:

• receive environment data from a wearable device sensor communicatively connected to the wearable device,
• wherein the wearable device is mountable on an arm of the user such that the wearable device sensor is directed toward a hand of the user, wherein the environment data comprises a representation of at least a portion of a calibrating object having at least one calibrating dimension of a predetermined size and a target machine-readable code having a determinable size;
• decode the target machine-readable code;
• determine a position of the wearable device on the arm of the user based on a first size of the calibrating object and a second size of the target machine-readable code;
• and
• alert the user to adjust the position of the wearable device based on the position of the wearable device relative to the calibrating object in an instance in which the position of the wearable device relative to the calibrating object exceeds a predetermined threshold.
