Information processing device, method and computer-readable non-transitory recording medium

摘要

An information processing device includes: a user information acquiring unit which acquires position information on a plurality of users in a range from which a directional display device is viewable; a user operation detecting unit which detects a first operation by a first user and a second operation by a second user; a response acquiring unit which acquires a response for notifying a user that an operation has been detected; and a display control unit which causes a response to the first operation be displayed by the directional display device so as to be visible from a position indicated by the position information on the first user and which causes a response to the second operation to be displayed by the directional display device so as to be visible from a position indicated by the position information on the second user.

1. An information processing device connected to a display device capable of varying contents to be viewed by users according to viewing directions, and executing user information management processing and user operation recognition processing, the information processing device comprising:
a position information acquiring unit to continuously or periodically acquire, regardless of presence or absence of detection of a user operation, position information indicating positions of a plurality of users in a range from which the display device is viewable; a user information retaining unit to retain user information including the position information on the users acquired by the position information acquiring unit; a user information updating unit to continuously or periodically update the user information by using the position information when the position information acquired by the position information acquiring unit is retained by the user information retaining unit, consequently keep the user information updated regardless of presence or absence of detection of a user operation; a user operation detecting unit to detect a first operation by a first user among the plurality of users and a second operation by a second user among the plurality of users who differs from the first user; a response acquiring unit to acquire a response for notifying a user that the operation has been detected; and a display control unit to calculate a direction of the first user and a direction of the second user relative to a display unit of the display device based on position information of the first user and position information of the second user being included in the user information, and cause a response to the first operation acquired by the response acquiring unit to be displayed by the display device so as to be visible from a position indicated by the position information on the first user, by causing the display device to output the response to the first operation with the direction of the first user as display direction, and also for causing a response to the second operation acquired by the response acquiring unit to be displayed by the display device so as to be visible from a position indicated by the position information on the second user, by causing the display device to output the response to the second operation with the direction of the second user as display direction, wherein the user information management processing is continuously or periodically executed by the position information acquiring unit, the user information retaining unit and the user information updating unit regardless of presence or absence of the detection by the user operation detecting unit, and the user operation recognition processing is executed by the user operation detecting unit, the response acquiring unit and the display control unit, and executed independently from the user information management processing.
