  • Patent number: 10915868
    Abstract: Life events relating to a user are displayed on a calendar. A user may navigate to different time periods in the calendar and see past life events relating to the user displayed on the calendar. The life events that are displayed on the calendar may include different types of content and be determined from different sources. For example, the life events for the time period may be: pictures, events, social media posts, messages, and the like. Different content sources may be used to locate the life events relating to the user. The life events that are selected for display on the calendar may be shown differently from other content that is included on the calendar. The life events may be processed to adjust an appearance of the life event before it is displayed. A user may also share a life experience with other users.

  • Patent number: 10535043
    Abstract: A calendar view smoothly and progressively transitions between different calendar views. Instead of snapping to a week view in response to changing from a month view to the week view, the month view progressively transitions to the week view while receiving an interaction. For example, the week view may smoothly expand while the view of the other weeks in the month smoothly decrease in size while the interaction is being received. A user may navigate between different calendar views such as year to month, month to week, week to multiple days, days to single days, and the like. When navigating month to month, week to week, day to day, and the like, the transitions between each time element are progressively and smoothly transitioned. Task information or other information that is displayed in the calendar progressively transitions to show more or less information depending on the interaction being received.

  • Patent number: 8856238
    Abstract: An application provides a “working elsewhere” status for users working at a location other than their regular work location and still available for meetings, communication sessions, etc. The application determines a user location being other than regular work location and the user still being available through user selection, information from user associated application(s), and/or from a presence notification. The application adjusts the user status to a working elsewhere status and makes the new status available to other applications such as calendaring, communication applications, presence service(s), and comparable ones. Meetings may be scheduled, communication sessions facilitated if the working elsewhere status is sufficient/acceptable for other users.
