Information processing apparatus and information processing method
Provided is an information processing apparatus that includes an estimation unit that estimates, based on sensing data provided by a plurality of sensors carried or worn by a user, a type of a moving body on which the user is riding. The information processing apparatus further includes a selection unit that selects information to be used for processing for obtaining a position of the user in the moving body using the type of the moving body estimated by the estimation unit.
1. An information processing apparatus, comprising:
a central processing unit (CPU) configured to:
receive first sensing data from a plurality of first sensors of a moving body, wherein the first sensing data indicates an attitude and motion amount of the moving body;
receive second sensing data from a plurality of second sensors, wherein the plurality of second sensors is wearable by a user riding the moving body;
correct the second sensing data based on the first sensing data;
estimate, based on the corrected second sensing data, a context of the user, wherein the context of the user indicates an action label of the user;
receive a relative position of the user with respect to the moving body;
generate map information based on the corrected second sensing data and the relative position of the user with respect to the moving body; and
obtain a position of the user in the moving body based on the context of the user and the map information.
2. The information processing apparatus according to claim 1 , wherein the CPU is further configured to select the map information.
3. The information processing apparatus according to claim 1 , wherein
the CPU is further configured to select the map information based on absolute positional information, and
the absolute positional information represents an absolute position of the moving body.
4. The information processing apparatus according to claim 1 , wherein the CPU is further configured to:
receive specific information from the moving body; and
select the map information based on the specific information.
5. The information processing apparatus according to claim 4 , wherein the specific information indicates that the position of the user is inside the moving body.
6. The information processing apparatus according to claim 1 , wherein the CPU is further configured to extract, as facility information, a point of interest in the moving body based on the position of the user in the moving body.
7. The information processing apparatus according to claim 1 , wherein the second sensing data includes one of acceleration data, angular velocity data, or geomagnetic data.
8. The information processing apparatus according to claim 1 , wherein the moving body is one of a train, an automobile, or a ship.
