Disclosed are a method and system that automatically adjust the tightness or looseness of the smart watch band (herein, smart watchband) throughout the day based on analysis of the smart watch function, a user's derived activity, and the requirements of the haptic motor to provide effective haptic feedback. The solution combines a self-adjusting smart watchband with a cognitive system that determines the optimal tightness of the band within a user's accepted boundary of comfort and then automatically adjusts the smart watchband for maximum benefit during an activity.
Method for Operating a Self -Adjusting Band for a Smart Watch
The fit of a smart watch band affects the functionality of the various sensors and haptic feedback motors embedded in the smart watch. The optimal tightness or looseness of the band on a user’s wrist (within an acceptable comfort level for the wearer) depends upon the user’s current activity and typically changes throughout the day. For example, a user might want to tighten the band during exercise, to maintain skin contact and ensure optimal sensor readings and effective haptic feedback.
A method is needed to ensure that the band on a smart watch has consistent skin contact that is appropriate to the user’s activity level and can continually collect data and provide haptic feedback as needed.
The novel solution is a method and system that automatically adjust the tightness or looseness of the smart watch band (herein, smart watchband ) throughout the day based on analysis of:
Smart watch function (i.e., taking a sensor reading, or retrying a failed sensor reading)
A user's derived activity (i.e., tighten the band when the user is exercising and loosen when sedentary)
Requirements of the haptic motor to provide effective haptic feedback
The solution combines a self-adjusting smart watchband with a cognitive system that determines the optimal tightness of the band within a user's accepted boundary of comfort, based upon the functions the smart watch is performing and the wearer’s activities. The core functions of the smart watchband automatically:
Tighten before taking a heart rate or similar sensor reading or to correct a malfunctioning sensor reading
Tighten or loosen for optimum comfort levels based on a user's derived activity Tighten to increase the strength of the haptic feedback, if the system detects that
haptic feedback is not being sensed by a wearer
The system comprises a smart watch fitted with a self-adjusting watchband. This disclosure does not lay claim to inventing the self-adjusting watchband itself, but the following two implementations could be used (Figure 1):
Extending clasp: the clasp either connecting the band to the smart watch or the clasp on the strap itself to put on and take off the watch can be fitted with a small motor, powered by the smart watch. This motor is used to contract or extend the smart watchband by a few millimeters, effectively tightening or loosening the band as it is worn on the user's wrist.
Air balloon: a small air balloon is fitted to the watchband and inflates or deflates to tighten or loosen the band as it is worn on the user's wrist.

In either case, the user puts the smart watch on the wrist and tightens the band to an acceptable, normal, level of comfort. The smart watchband tightens or loosens by a few millimeters as required.
