Abstract

A moving context and a moving time of a user are specified by acceleration information while the user is moving. The moving context represents the user'"'"'s moving status. The acceleration information is measured by an acceleration sensor carried with the user. The moving context and the moving time are stored in time series. The moving context and the moving time between a moving start time and an arrival time are set as a moving pattern. A tag is set to the moving context in the moving pattern. The tag identifies a function to be executed for the moving context. A moving estimation pattern is generated as the moving pattern having the moving context and the moving time specified by acceleration information measured when the user is newly moving. The function identified by the tag is executed, when the moving context set with the tag in the moving estimation pattern coincides with a moving context specified by acceleration information measured while the user is newly moving.

Claims

1. An apparatus for processing information, comprising:

a specifying unit configured to specify a moving context and a moving time of a user by acceleration information while the user is moving, the moving context representing a moving means of the user, the acceleration information being measured by an acceleration sensor carried with the user;

a storage unit configured to store the moving context and the moving time in time series;

a pattern setting unit configured to set a time sequence of the moving context and the moving time stored in the storage unit, from a moving start time to an arrival time to a destination, as a moving pattern from the moving start time;

a tag setting unit configured to set a tag to the moving context in the moving pattern, the tag representing a place where the user exists and identifying a function to be executed at the place;

an estimation unit configured to generate a moving estimation pattern as the moving pattern having the moving context and the moving time specified by acceleration information which is measured when the user is newly moving; and

an execution unit configured to execute the function identified by the tag, when the moving context set with the tag in the moving estimation pattern coincides with a moving context specified by acceleration information which is measured while the user is newly moving.

2. The apparatus according to claim 1, wherein

the moving context is the user'"'"'s walking or the user'"'"'s riding on a vehicle.

3. The apparatus according to claim 1, wherein,

while the user is newly moving,

the estimation unit estimates change from the moving context to another moving context by referring to a transition probability that a plurality of moving contexts mutually transfers.

4. The apparatus according to claim 1, wherein

the pattern setting unit sets at least one of the moving start time and a day of the week when the user is moving in correspondence with the moving pattern.

5. The apparatus according to claim 1, wherein

the tag setting unit sets a tag to a time before the moving start time of the moving pattern, a time after the arrival time of the moving pattern, or a time between the arrival time of the moving pattern to the moving start time of another moving pattern.

6. The apparatus according to claim 1 or 4, wherein

the moving pattern has the moving context “

walking” and

the moving context “

riding”

mutually, and a moving time corresponding to each moving context, the moving time having a time sequence number.

7. The apparatus according to claim 6, wherein,

the user begins to move newly,

the estimation unit selects the moving pattern corresponding the moving start time and the day of the week, and sets a status of the selected moving pattern as “

before pattern”

.

8. The apparatus according to claim 7, wherein

the estimation unit decides whether the moving time of the moving context “

walking”

in the selected moving pattern coincides with a moving time of the moving con text “

walking”

measured while the user is newly moving.

9. The apparatus according to claim 8, wherein,

if the moving time of the moving context “

walking”

in the selected moving pattern coincides with a moving time of the moving context “

walking”

measured while the user is newly moving,

the estimation unit sets the selected moving pattern as the moving estimation pattern, and sets the status of the moving estimation pattern as “

inter-pattern”

.

10. The apparatus according to claim 9, wherein,

whenever the moving context changes to another moving context while the user is newly moving,

the estimation unit updates the time sequence number of the moving time in the moving estimation pattern, and decides whether the time sequence number of the moving estimation pattern is completed.

11. The apparatus according to claim 10, wherein,

if the time sequence number of the moving estimation pattern is completed,

the estimation pattern sets the status of the moving estimation pattern as “

after pattern”

.

12. A method for processing information, the method being executed by a computer, comprising:

specifying a moving context and a moving time of a user by acceleration information while the user is moving, the moving context representing a moving means of the user, the acceleration information being measured by an acceleration sensor carried with the user;

storing the moving context and the moving time in time series, in a memory;

setting a time sequence of the moving context and the moving time stored in the memory, from a moving start time to an arrival time to a destination, as a moving pattern from the moving start time;

setting a tag to the moving context in the moving pattern, the tag representing a place where the user exists and identifying a function to be executed at the place;

generating a moving estimation pattern as the moving pattern having the moving context and the moving time specified by acceleration information which is measured when the user is newly moving; and

executing the function identified by the tag, when the moving context set with the tag in the moving estimation pattern coincides with a moving context specified by acceleration information which is measured while the user is newly moving.

13. A non-transitory computer readable medium storing program codes for causing a computer to process information, the program codes comprising:

a first program code to specify a moving context and a moving time of a user by acceleration information while the user is moving, the moving context representing a moving means of the user, the acceleration information being measured by an acceleration sensor carried with the user;

a second program code to store the moving context and the moving time in time series, in a memory;

a third program code to set a time sequence of the moving context and the moving time stored in the memory, from a moving start time to an arrival time to a destination, as a moving pattern from the moving start time;

a fourth program code to set a tag to the moving context in the moving pattern, the tag representing a place where the user exists and identifying a function to be executed at the place;

a fifth program code to generate a moving estimation pattern as the moving pattern having the moving context and the moving time specified by acceleration information which is measured when the user is newly moving; and
