the display controller is further configured to make a simplified display of the notification information in the gaze direction peripheral region based on the direction of the gaze and the head orientation peripheral region based on the orientation of the head.
5. The information processing apparatus according to claim 3 , wherein the real object is a subject of interest on which it is estimated that the user is interested in the subject of interest, and
the display controller is further configured to
estimate that a real object that is positioned in a gaze direction central region that is a central region of a region based on the direction of the gaze is the subject of interest, and
make a simplified display of information on the subject of interest in the head orientation peripheral region based on the orientation of the head and the gaze direction peripheral region based on the direction of the gaze.
6. The information processing apparatus according to claim 4 , wherein the display controller is further configured to determine whether a condition for ending the simplified display is met based on at least any one of the shift in the gaze and the move of the head and, when the condition for ending the simplified display is met, end the simplified display.
7. The information processing apparatus according to claim 6 , wherein the condition for ending the simplified display is based on whether the gaze is on the simplified display for a certain time.
8. The information processing apparatus according to claim 7 , wherein the display controller is further configured to end the simplified display when the gaze is turned to the simplified display but the gaze shifts before the certain time elapses.
9. The information processing apparatus according to claim 4 , wherein the display controller is further configured to perform display control to enhance the simplified display when the simplified display is positioned in a gaze direction central region that is a central region of a region based on the direction of the gaze and a certain time elapses.
10. The information processing apparatus according to claim 4 , wherein the display controller is further configured to switch the simplified display to a detailed display when the head is turned to the simplified display and the simplified display is positioned in a gaze direction central region that is a central region in the region based on the direction of the gaze and in a head orientation central region that is a central region of the region based on the orientation of the head.
11. The information processing apparatus according to claim 10 , wherein the display controller is further configured to determine whether a condition for ending the detailed display is met based on at least any one of the shift in gaze and the move of the head and, when the condition for ending the detailed display is met, end the detailed display.
12. The information processing apparatus according to claim 11 , wherein the condition for ending the detailed display is based on whether the gaze is on the detailed display for a certain time.
13. The information processing apparatus according to claim 12 , wherein the display controller is further configured to end the detailed display when the gaze shifts from the detailed display before the certain time elapses.
14. The information processing apparatus according to claim 1 , wherein the recognition unit is further configured to recognize the shift in gaze based on a move of an eye of the user.
15. An information processing method comprising:
by a processor,
recognizing a shift in gaze and a move of a head of a user;
controlling display of information on a subject according to the move of the head that is made after the gaze is turned to the subject;
making a simplified display of information on the subject in a head orientation peripheral region and a gaze direction peripheral region, based on the head orientation peripheral region overlapping with the gaze direction peripheral region,
wherein the head orientation peripheral region is peripheral to a region set based on an orientation of the head,
wherein the gaze direction peripheral region is peripheral to another region set based on a direction of the gaze, and
wherein a real object is a subject of interest on which it is estimated that the user is interested in the subject of interest;
estimating that a real object that is positioned in a gaze direction central region that is a central region of a region based on the direction of the gaze is the subject of interest; and
