CROSS REFERENCE TO RELATED APPLICATIONS

This application is a U.S. National Phase of International Patent Application No. PCT/JP2019/025279 filed on Jun. 26, 2019, which claims priority benefit of Japanese Patent Application No. JP 2018-167822 filed in the Japan Patent Office on Sep. 7, 2018. Each of the above-referenced applications is hereby incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to an information processing apparatus, an information processing method, and a program.

BACKGROUND ART

Recently, a technique has been developed that shares the experience of a first user with a second user through the vision, in a case where there are multiple users.

Patent Literature 1 discloses a technique in which an image expressing a field of view of the first user is generated on the basis of a captured image captured by an imaging unit worn on the head of the first user, and in which the image is presented to the second user. With this method, it is possible to provide an appropriate image to the second user when sharing the experience through the vision between the users.

In addition, in recent years, a technology that displays a motion of a user's eye gaze as a circle, a line, a heat map, or the like may sometimes be used to visualize and analyze the eye gaze.

SUMMARY OF THE INVENTION

Problem to be Solved by the Invention

However, in a technique disclosed in Patent Literature 1, although a field of view of a first user is expressed to a second user, it is not possible for the second user to understand the event or the like that the first user focuses on in the field of view, and it is not possible for the second user to sufficiently understand the intention of the first user.

In addition, if a circle or a line, a heat map, or the like is used to represent the focused event in the field of view of the first user, a location viewed by the first user or the second user may be hidden.

For example, in a medical field, an assistant may sometimes operate various devices to perform a surgery while drawing the intention of an operator. At this time, drawing the operator's intention has been left to the assistant's ability, which can influence the smoothness of the surgery, etc. depending on the assistant's skill. In the medical field, an affected site region may be hidden if the event focused by the operator is indicated by the circle, the line, the heat map, or the like, which can possibly influence the surgical operation.

Accordingly, although it is not limited to the medical field, a case in which a target object gazed by the first user is hidden upon expressing the field of view of the first user to the second user can influence the second user sharing the field of view with the first user. Therefore, a technique has been demanded that shares a gazing point of the first user with the second user without hiding the target object.

Means for Solving the Problem

The present disclosure provides an information processing apparatus that includes: a movement history acquiring section that acquires a movement history, based on an absolute coordinate, of a gazing point of a first user that gazes at a display region, in which the absolute coordinate is in a three-dimensional space displayed in the display region; and a display controller that controls a display unit that displays the display region to visualize, to a second user, the movement history of the gazing point.

In addition, the present disclosure provides an information processing method that causes a processor to execute a process that includes: acquiring a movement history, based on an absolute coordinate, of a gazing point of a first user that gazes at a display region, in which the absolute coordinate is in a three-dimensional space displayed in the display region; and controlling a display unit that displays the display region to visualize, to a second user, the movement history of the gazing point.

In addition, the present disclosure provides a program that causes a computer to function as: a movement history acquiring section that acquires a movement history, based on an absolute coordinate, of a gazing point of a first user that gazes at a display region, in which the absolute coordinate is in a three-dimensional space displayed in the display region; and a display controller that controls a display unit that displays the display region to visualize, to a second user, the movement history of the gazing point.

According to the present disclosure, the display unit is controlled to visualize, to the second user, the movement history of the gazing point of the first user.

Effect of the Invention

As described above, according to the present disclosure, it is possible to share the gazing point of the first user with the second user without hiding a target object when the first user gazes at the target object. This allows the second user to understand the intention of the first user with respect to the target object. It is to be noted that the above-described effects are not necessarily limitative, and any of effects described in the present specification or other effects that may be understandable from the present specification may be achieved in addition to the above-described effects or instead of the above-described effects.
