Calendaring Location-Based Events and Associated Travel

Abstract

A user interface for an electronic calendar represents different locations or different users or different user calendars in different portions of the display. Calendar entries can be associated with one or more locations, one or more users, and with one or more user calendars. The different locations may reside in different time zones and a timeline for each time zone is displayed. The position of the calendar entry provides a visual identifier of the timeline with which the event is associated. Travel time to and from events in the calendar are calculated for calendared events and shown adjacent to the beginning and end of the event. A user's future location at a point in time is inferred from patterns in the user's locations and by analyzing the user's calendared events and correspondence in order to calculate travel time to calendared events.

1 . A computer-implemented method of presenting a graphical user interface displaying an electronic calendar having calendar entries associated with one or more calendar entities, the method comprising:
 simultaneously displaying a first portion of a user interface corresponding to a first calendar entity and a second portion of the user interface corresponding to a second calendar entity, the second calendar entity different from the first calendar entity; and   displaying calendar entries associated with both the first and second calendar entities as spanning the first and second portions of the user interface.   
   
   
       2 . The method of  claim 1 , wherein the first calendar entity represents a first person and the second calendar entity represents a second person, and wherein calendar entries that span the first and second portions of the user interface involve both the first person and the second person. 
   
   
       3 . The method of  claim 1 , wherein the first calendar entity represents a first location and the second calendar entity represents a second location, and wherein calendar entries that span the first and second portions of the user interface are associated with both the first location and the second location. 
   
   
       4 . The method of  claim 3 , further comprising:
 displaying calendar entries associated with only the first calendar entity in the first portion of the user interface; and   displaying calendar entries associated with only the second calendar entity in the second portion of the user interface.   
   
   
       5 . The method of  claim 3 , wherein the calendar entries are represented by enclosed shapes, wherein the enclosed shapes overlap the one or more timelines relevant to the calendar entries' associated one or more locations at times for the respective calendar entries. 
   
   
       6 . The method of  claim 5 , wherein for calendar entries that are not associated with any particular calendar entity or are not associated with a calendar entity currently displayed, the enclosed shapes overlap the one or more timelines relevant to people participating in events represented by the calendar entries. 
   
   
       7 . The method of  claim 1 , wherein the first calendar entity represents a first time zone and the second calendar entity represents a second time zone, and wherein calendar entries that span the first and second portions of the user interface are associated with both the first time zone and the second time zone. 
   
   
       8 . The method of  claim 7 , further comprising:
 displaying a timeline relevant to the first time zone in the first portion and a second timeline relevant to the second time zone in the second portion.

       19 . A computer-readable storage medium storing executable computer program instructions for presenting a graphical user interface displaying an electronic calendar having calendar entries associated with one or more calendar entities, the computer program instructions comprising instructions for:
 simultaneously displaying a first portion of a user interface corresponding to a first calendar entity and a second portion of the user interface corresponding to a second calendar entity, the second calendar entity different from the first calendar entity; and   displaying calendar entries associated with both the first and second calendar entities as spanning the first and second portions of the user interface.   
   
   
       20 . The computer-readable storage medium of  claim 19 , wherein the first calendar entity represents a first person and the second calendar entity represents a second person, and wherein calendar entries that span the first and second portions of the user interface involve both the first person and the second person. 
   
   
       21 . The computer-readable storage medium of  claim 19 , wherein the first calendar entity represents a first location and the second calendar entity represents a second location, and wherein calendar entries that span the first and second portions of the user interface are associated with both the first location and the second location. 
   
   
       22 . The computer-readable storage medium of  claim 21 , wherein the computer program instructions further comprise instructions for:
 displaying calendar entries associated with only the first calendar entity in the first portion of the user interface; and   displaying calendar entries associated with only the second calendar entity in the second portion of the user interface.   
   
   
       23 . The computer-readable storage medium of  claim 21 , wherein the calendar entries are represented by enclosed shapes, wherein the enclosed shapes overlap the one or more timelines relevant to the calendar entries' associated one or more locations at times for the respective calendar entries. 
   
   
       24 . The computer-readable storage medium of  claim 23 , wherein for calendar entries that are not associated with any particular calendar entity or are not associated with a calendar entity currently displayed, the enclosed shapes overlap the one or more timelines relevant to people participating in events represented by the calendar entries. 
   
   
       25 . The computer-readable storage medium of  claim 19 , wherein the first calendar entity represents a first time zone and the second calendar entity represents a second time zone, and wherein calendar entries that span the first and second portions of the user interface are associated with both the first time zone and the second time zone. 
   
   
       26 . The computer-readable storage medium of  claim 25 , wherein the computer program instructions further comprise instructions for:
 displaying a timeline relevant to the first time zone in the first portion and a second timeline relevant to the second time zone in the second portion.   
   
   
       27 - 37 . (canceled)
