Context diary application for a mobile terminal
View Patent ↗The invention provides a presentation of contextual information to a digital device in relation to a period of time. As such the invention provides for efficient user access to historical, as well as, current and future or forecasted contextual information. In addition, the present invention provides for current contextual information to be presented in an idle mode view, a scrolling bar mode view or another inconspicuous view. Additionally the present invention provides a novel means of using context information to create multimedia file presentations; image or video file presentations that can be associated with previous periods of time, locations or other context data.
1. A mobile terminal comprising:
two or more sensors for sensing two or more types of context data;
a sensor application program interface (API) for processing the sensed data to provide one or more context atoms relating to specific pieces of context-related information, wherein each context atom comprises an entity having an associated name, value, source, and date;
a context engine for receiving and storing the context atoms, the context engine including a context silo for storing the context atoms and a context API for allowing one or more user applications to access the context data;
a data store coupled to the context engine for storing information related to a user;
a privacy engine for providing security;
a communications manager for identifying context sources external to the mobile terminal and initiating contact with the external context sources; and
a display for presenting the context-related information and/or information from the external context sources in the manner of a diary,
wherein the context atoms are stored in a blackboard within the context silo, and the blackboard provides an API for querying and setting the context atoms.
2. The mobile terminal of claim 1 , wherein the context silo further comprises a subscription manager for providing subscriptions to one or more of the context atoms and for providing notifications in the event of a change in the context atoms.
3. The mobile terminal of claim 2 , wherein the subscription manager periodically polls the context atoms based upon the subscriptions and notifications.
4. The mobile terminal of claim 1 , wherein the one or more context atoms further includes attributes including metadata information, the metadata information associated with reliability of the context-related information.
5. The mobile terminal of claim 4 , wherein the metadata information further includes information associated with accuracy, source, and time of creation.
6. The mobile terminal of claim 1 , wherein operation of the privacy engine is responsive to the information related to the user.
7. The mobile terminal of claim 6 , wherein the information related to the user comprises user preferences, profile information, and/or permissions for the privacy engine.
8. The mobile terminal of claim 1 , further comprising a time-line based user interface, wherein the time-line based user interface is used to display the context information in relation to a period of time.
9. A method comprising:
sensing, in a mobile terminal, two or more types of context data;
processing the sensed data to provide one or more context atoms relating to specific pieces of context-related information, wherein each context atom comprises an entity having an associated name, value, source, and date;
receiving and storing the context atoms in a blackboard within a context engine, wherein the blackboard provides an application program interface (API) for querying and setting the context atoms;
storing, in a data store, information related to a user;
providing different levels of security based on the information related to the user;
identifying context sources external to the mobile terminal and initiating contact with the external context sources; and
using the context-related information and external context sources to provide a presentation on the mobile terminal of multimedia files.
10. The method of claim 9 , wherein the one or more context atoms further includes attributes including metadata information, the metadata information associated with reliability of the context-related information.
11. The method of claim 10 , wherein the metadata information further includes information associated with accuracy, source, and time of creation.
12. The method of claim 9 , wherein operation of a privacy engine is responsive to the information related to the user.
13. The method of claim 12 , wherein the information related to the user comprises user preferences, profile information, and/or permissions for the privacy engine.
14. The method of claim 9 , further comprising:
providing time-line information; and
displaying the context information in relation to a period of time.
