Abstract

A portable type information processing apparatus includes a plurality of sensing units that acquire information convertible into place information indicating a current location and detect an event which occurs in relation to the place information obtained through conversion from the information, a storage unit that stores event transition information indicating a relation between order of transitions between events and transition time periods spent on the transitions, and a control unit that obtains, as a current event, a latest event and controls an operating state of a sensing unit to detect a transition destination event of an event corresponding to the current event in the event transition information based on a relation between a transition time period spent on a transition from the event to the transition destination event in the event transition information and an elapsed time period since detection of the current event.

First claim

What is claimed is:

1. A portable type information processing apparatus comprising:
a plurality of sensing units that acquire information convertible into place information indicating a current location of the portable type information processing apparatus and detect an event which occurs in relation to the place information obtained through conversion from the information;
a storage unit that stores event transition information indicating a relation between order of transitions between events acquired by the plurality of sensing units and transition time periods spent on the transitions; and
a control unit that obtains, as a current event, a latest event detected by any one of the plurality of sensing units and controls an operating state of a sensing unit to detect a transition destination event of an event corresponding to the current event in the event transition information based on a relation between a transition time period spent on a transition from the event corresponding to the current event to the transition destination event in the event transition information and an elapsed time period since detection of the current event,
wherein the control unit performs an acquisition of an event transition with the latest event as an origin based on the event transition information, an extraction of one or more first events, a total transition time period from the origin of which is less than the elapsed time period, a selection of one or more first sensing units detecting the one or more first events in the event transition information, and a control of the plurality of sensing units that turns off one or more second sensing units which are unselected or makes an operation interval for each of the one or more second sensing units longer than an operation interval for each of the one or more first sensing units.

2. The portable type information processing apparatus according to claim 1 ,
wherein the control unit repeatedly executes, with predetermined frequency, the extraction of the event and the control of the plurality of sensing units until a new event is detected by any one of the plurality of sensing units.

3. The portable type information processing apparatus according to claim 1 ,
wherein when absolute coordinates are acquired by one of the plurality of sensing units, and a current location obtained from the absolute coordinates is within a predetermined region, in a state where no event is detected, the control unit sets as the origin a stay event indicating a stay within the predetermined region in the event transition information.

4. The portable type information processing apparatus according to claim 3 ,
wherein when the current location is within a plurality of regions, the control unit sets as the origin a stay event indicating a stay within a region, a boundary of which is closest to the current location.

5. The portable type information processing apparatus according to claim 1 ,
wherein when absolute coordinates are acquired by one of the plurality of sensing units, and a current location obtained from the absolute coordinates is within no region, in a state where no event is detected, the control unit sets as the origin an exit event indicating an exit from a region, a boundary of which is closest to the current location.

6. The portable type information processing apparatus according to claim 1 , further comprising
a second storage unit that stores an event detection ratio for each of the plurality of sensing units,
wherein when the plurality of sensing units do not include a sensing unit capable of acquiring absolute coordinates, the control unit determines an operation interval for each of the sensing units according to the event detection rate for the sensing unit obtained from the second storage unit in a state where no event is detected.

7. The portable type information processing apparatus according to claim 1 ,
wherein the control unit calculates, for each of the one or more first sensing units, probability of use based on the one or more first events and determines an operation interval according to the probability of use.

8. The portable type information processing apparatus according to claim 7 ,
wherein the control unit calculates, as the probability of use for each of the one or more first sensing units, proportion of a total number of first events detected by the each of the one or more first sensing units to a total number of the one or more first event.

9. The portable type information processing apparatus according to claim 7 ,
wherein the event transition information includes the numbers of logs generated for the transitions between the events acquired by the plurality of sensing units, and
the control unit weights each of the one or more first events according to the number of logs of transitions between the latest event and the one or more first events based on the event transition information, weights a first total number of the one or more first event and second total numbers of first event detected by the each of the one or more first event based on weights for the one or more first events, and calculates, as the probability of use for each of the one or more first sensing units, proportion of a weighted value of a second total number to a weighted value of the first total number.

10. The portable type information processing apparatus according to claim 1 ,
wherein the event transition information includes the number of logs of each of the transitions between the events acquired by the plurality of sensing units and a distribution of a transition time period for the each of the transitions between the events, and
the control unit calculates, for each of the one or more first sensing unit, proportion of a first number of logs to a second number of logs, the first number of logs of transitions of which transition destinations are first events detected by a first sensing unit in a time range corresponding to the elapsed time period in the distribution, and the second number logs of transitions included in the event transitions between the latest event and the one or more first events, and determines an operation interval according to the proportion.

11. An information processing system comprising
a plurality of portable type information processing apparatuses and a server, the plurality of portable type information processing apparatuses including a plurality of sensing units that acquire information convertible into place information indicating a current location of the portable type information processing apparatus and detect an event occurring in relation to the place information obtained through conversion from the information,
wherein the server includes
a reception unit that receives history information on an event detected by the plurality of portable type information processing apparatuses,
a generation unit that compiles the history information and generates event transition information indicating a relation between order of transitions between events acquired by the plurality of sensing units and transition time periods spent on the transitions, and
a transmission unit that transmits the event transition information to the plurality of portable type information processing apparatuses, and
the plurality of portable type information processing apparatuses each include
a reception unit that receives the event transition information,
a storage unit that stores the event transition information, and
a control unit that obtains, as a current event, a latest event detected by any one of the plurality of sensing units and controls an operating state of a sensing unit to detect a transition destination event of an event corresponding
