Efficiency-of-use techniques

摘要

A method for associating an efficiency-of-use-score may include, but is not limited to: associating a physical product with a user account in response to a signal indicating that a user has control of the physical product; generating an efficiency-of-use score based on information associated with how the physical product is used during a period of time that the user has control of the physical product; and associating the efficiency-of-use score with the user account.
