  • Patent number: 11372955
    Abstract: Methods and systems for authorizing and enabling a virtual assistant or meeting host temporary access to one's own data during an activity or meeting event. A user is offered various options for enabling the temporary access to the virtual assistant prior to a scheduled meeting, and during impromptu meetings. The user can specify the duration that the access should be valid, a system can automatically disable the temporary access at the termination of the meeting event and/or if the user is no longer a participant at the meeting event. The authorization can be configured to target specific types of data and types of access.

  • Patent number: 10868684
    Abstract: The present disclosure relates to processing operations configured for management of proactive suggestion(s) that may be utilized to manage the sharing of meeting content. The present disclosure further describes optimization of a user interface whereby a user interface experience is improved through new user interface features and actions that enable proactive presentation of suggestions for syncing content with a meeting as well as sharing synced content. Various intelligent signals such as user's calendar, GPS location, camera roll content, capture content (including OCR, whiteboard detection, etc.) and capture time, are collected and analyzed to make smart suggestions to the user to share content with specific set of people (e.g., those involved in meeting).
