Information processing device and information processing method
An information processing device includes: a recognition unit ( 21 ) that recognizes a surrounding environment of a current position of a user; a guide control unit ( 22 ) that generates guide information corresponding to a characteristic of the user by using a recognition result of the recognition unit and that causes an output device to perform an output thereof; and a change detection unit ( 23 ) that detects a changed portion in the surrounding environment of the current position in a case where it is determined that the user has visited the current position in the past, wherein in a case where the change detection unit detects the changed portion, the guide control unit generates the guide information including information causing the user to recognize the changed portion.
1. An information processing device, comprising:
a central processing unit (CPU) configured to:
recognize a surrounding environment of a current position of a user;
generate guide information based on the recognized surrounding environment, wherein the guide information corresponds to a characteristic of the user:
control, based on the generated guide information, an output device to perform an output; and
detect a changed portion in the surrounding environment of the current position based on determination that the user has visited the current position in a past, wherein the guide information includes information that causes the user to recognize the changed portion.
2. The information processing device according to claim 1 , wherein the CPU is further configured to detect the changed portion based on an image acquired by imaging of the surrounding environment of the current position and a history image acquired by imaging of the surrounding environment of the current position in the past.
3. The information processing device according to claim 2 , wherein the CPU is further configured to determine, based on the current position and positional information associated with the history image, whether the user has visited the current position in the past.
4. The information processing device according to claim 1 , wherein the CPU is further configured to control the output device to output the guide information by an output method corresponding to the characteristic of the user.
5. The information processing device according to claim 4 , wherein the output method corresponds to a display output and an audio output.
6. The information processing device according to claim 1 , wherein the CPU is further configured to:
generate the guide information to guide the user to a destination; and
update, based on a change in an optimal route to the destination, the guide information according to the changed optimal route.
7. The information processing device according to claim 1 , wherein the characteristic of the user indicates audiovisual ability of the user.
8. The information processing device according to claim 1 , wherein the characteristic of the user indicates an eye level of the user.
9. The information processing device according to claim 1 , wherein the characteristic of the user indicates a nationality of the user.
10. The information processing device according to claim 1 , wherein the characteristic of the user includes whether the user is likely to get lost.
11. An information processing method, comprising:
in an information processing device:
a recognizing a surrounding environment of a current position of a user;
generating guide information based on the recognized surrounding environment, wherein the guide information corresponds to a characteristic of the user;
controlling, based on the generated guide information, an output device to perform an output; and
detecting a changed portion in the surrounding environment of the current position based on determination that the user has visited the current position in a past, wherein the guide information including information that causes the user to recognize the changed portion.
12. A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
a recognizing a surrounding environment of a current position of a user;
generating guide information based on the recognized surrounding environment, wherein the guide information corresponds to a characteristic of the user;
controlling, based on the generated guide information, an output device to perform an output; and
detecting a changed portion in the surrounding environment of the current position based on determination that the user has visited the current position in a past, wherein the guide information including information that causes the user to recognize the changed portion.
