Abstract: An information processing system (10) comprises: a rotation control unit (110) that makes a first camera (18) and a second camera (19) having a same rotation axis rotate on the rotation axis depending on a position of a target to be imaged; an acquisition unit (120) that acquires a first living body information from an image taken by the first camera and acquires a second living body information from an image taken by the second camera; an authentication unit (130) that executes authentication processing using the first living body information and the second living body information; and an execution unit (140) that executes, in a case that the authentication processing is successful, predetermined processing in a facility that the target uses. By such an information processing system, it is possible to execute authentication processing on the target with high accuracy and appropriately execute the predetermined processing.

Abstract: Provided is a technique in which, in arranging a virtual object with respect to a real space, a user has less trouble, usability is good, and the object is suitably placeable. A head mounted display apparatus (HMD apparatus) according to one embodiment has a function of arranging and displaying the virtual object in a space based on an operation by a user. The HMD apparatus displays, on a display surface, a grid including a plurality of points for supporting an operation of the virtual object, and disposes and displays, according to an operation includes designation of a target virtual object and designation of a first point at an arrangement destination, the target virtual object at the position of the first point.

Abstract: A memory includes: a magnet including a first and second portions adjacent in a first direction. The first portion has a first dimension in a second direction at a first position at which a dimension of the magnet in the second direction is maximum, the second direction perpendicular to the first direction, the second portion has a second dimension in the second direction at a second position at which a dimension of the magnet in the second direction is minimum, the second dimension smaller than the first dimension, the first portion is continuous to the second portion via a third position between the first and second positions, a curve corresponding to an outer of the magnet extends between the first and third positions, and the curve passes through a side closer to the central axis of the magnet than a straight line connecting the first and second positions.

Abstract: An estimation device (10) receives a device ID for identifying a device in a network and an observation event that has occurred in the device from a user terminal (20) as an input. The estimation device (10) acquires attribute information of the device corresponding to the received device ID from a device information storage unit (13c), estimates a risk that the device in the network is subject to an attack on the basis of the acquired attribute information and the received observation event, and outputs the estimated attack risk to the user terminal (20).

Abstract: In a linked display system in which wireless communication connection between a first information device and a second information device has been established, when the first information device transmits text data to the second information device in a state of displaying content containing the text data and image data, the second information device displays the text data while the first information device stops displaying the text data and enlarges and displays the image data.
