Patent number: 11443060Abstract: When a user approaches or accesses a device, the device attempts to recognize the user. A multi-user note management system takes different actions based on whether the user is recognized as the owner of the device, is recognized as a known user of the device, or is determined to be an unknown user of the device. If the user is recognized as the owner or a known user, the system receives user input and stores the user input as a note. If the user is an unknown user, the system does not allow the user to leave a note at the device, or receives user input and captures an image of the user, and stores the user input as a note associated with the captured image. When the owner of the device unlocks the device after a note has been left, the system displays or otherwise presents the notes.Type: GrantFiled: October 29, 2019Date of Patent: September 13, 2022Assignee: Motorola Mobility LLCInventors: Amit Kumar Agrawal, Alexandre Neves Creto
