8 . The information processing device according to claim 5 , wherein a correspondence relation between a type of an object and a type of the display control is set in advance, and
wherein in the control processing, display control corresponding to a type of the control object in the movement, the size reduction, the transparency, and the non-display is executed to the control object.
9 . The information processing device according to claim 1 , wherein in the control processing, control is executed such that highlighted display of the control object selected in the selecting processing is executed.
10 . The information processing device according to claim 9 , wherein in the control processing, control is executed such that the highlighted display of the control object is performed for a period since the control object was selected in the selecting processing until display control of the control object is started or the predetermined operation is finished.
11 . A head mounted display comprising:
the information processing device according to claim 1 ; and
a display which displays an image in which display of the control object is controlled.
12 . An information processing method comprising:
a selecting step of selecting, as a control object, a virtual object present at a line-of-sight position of a user wearing a head mounted display;
a first determining step of determining whether or not the user performed a predetermined operation for visually recognizing a rear of the control object;
a second determining step of determining that the predetermined operation has finished in a case where at least either one of a movement amount and a rotation amount of a head part of the user from a positional attitude of the head part of the user when it is determined that the predetermined operation has been performed is larger than a threshold value; and
a control step of executing control that the control object is moved and displayed such that a portion hidden by the control object can be visually recognized in response to determining in the first determining step that the predetermined operation has been performed by the user, and executing control that the control object is returned to an original position in response to determining in the second determining step that the predetermined operation has finished,
wherein in the control step, (1) a direction in which the control object is to be moved is determined based on at least either one of a moving direction and a rotating direction of the head part of the user, or (2) a distance for which the control object is to be moved is determined based on at least either one of a movement amount and a rotation amount of the head part of the user.
13 . A non-transitory computer-readable medium storing a program that causes a computer to execute an information processing method, the information processing method comprising:
