A wearable device is disclosed. The wearable device comprises: a camera; a sensor; a display; a laser projector; and a processor for identifying a user's sight line on the basis of sensing data obtained by the sensor, identifying location information of at least one object included in an image obtained by the camera, and controlling the laser projector to provide, on the display, augmented reality (AR) information related to the object on the basis of the identified user's sight line and location information of the object, wherein the laser projector comprises: a light emitting element for emitting a laser light; a focus adjusting element for adjusting a focus of the emitted laser light; and a scanning mirror for controlling a scan direction of the light having the adjusted focus, and the processor controls a driving state of the focus adjusting element on the basis of the identified user's sight line and location information of the object.

An interaction peripheral, a method for detecting a real point, a virtual reality headset, a method for reproducing a real point in virtual space, a device and a method for virtualising a real space, particularly allowing a plane to be obtained in two, three or n dimensions of a real space which may be reproducible in virtual reality. An interaction peripheral which can be connected to a virtual reality headset, includes a range finder which can supply, to the headset, a measurement signal including a relative position measurement of a real point of a real space, the real point being sighted by the range finder. The measurement signal enables reproduction of the real point measured in a virtual space generated by the headset. Thus, the real point can be reproduced in real space while reducing risks of errors because the measurement tools are simple interaction peripherals handled by a user.

Provided are a bilateral limb coordination training system and a bilateral limb coordination training control method. The bilateral limb coordination training control method includes: detecting, by a force sensor, force information of a three degree-of-freedom bilateral motion mechanism and sending the force information to a main controller; determining, by the main controller, target motion information of the three degree-of-freedom bilateral motion mechanism of a robot according to the force information; and controlling, by the main controller, the three degree-of-freedom bilateral motion mechanism to perform a corresponding motion based on the target motion information and sending training data and running status information generated during training to an upper computer; where a training instruction includes a bilateral non-association motion training instruction, a bilateral flexible-association motion training instruction or a bilateral rigid-association motion training instruction.

An image display method includes: obtaining a homography matrix between a first target plane and a second target plane according to the first target plane and the second target plane; obtaining a target displacement according to the homography matrix and an attitude; obtaining a target pose according to the target displacement, the target pose including a position and an attitude of a camera coordinate system of a current frame image in a world coordinate system; and displaying an AR image according to the target pose.

A student terminal is for viewing a class given in a virtual space that is immersive. The student terminal includes: a VR function section configured to display the virtual space according to virtual space information; and an input section for receiving a video capturing a desk of a student who views the class. The VR function section extracts, from the video, an area including a top plate of the desk corresponding to a desk object in the virtual space, and performs image composition for fitting a video capturing the area onto a top plate of the desk object.

An information processing system comprising a portable information device, a relay apparatus that connects the portable information device to a network, and a server. The server includes a library in which, for each relay apparatus, an area where the relay apparatus is present is registered in association with relay apparatus identification information. The portable information device obtains connection authentication from the relay apparatus installed in an area where the own device is present, and when the authentication is successful, the relay apparatus that provides the authentication transmits the relay apparatus identification information to the server.

A video display device comprising; a display; an exercise amount detection sensor configured to detect an exercise amount of a viewer while the viewer is viewing content displayed and output sensor information; a timer that measures a viewing time; and a processor. The processor: acquires the viewing time from the timer; calculates the exercise amount of the viewer based on the sensor information acquired within a predetermined period of viewing time; compares the exercise amount with an exercise facilitation threshold for determining whether to facilitate exercise for the viewer; displays a specific object within a display area of the display when the exercise amount falls below the exercise facilitation threshold; and moves the specific object from an inside of the display area to an outside thereof in accordance with an external coordinate system expressing a position in a real space associated with a two-dimensional coordinate system in the display area.

An information processing device is provided which includes a first acquisition unit (214) configured to acquire a control command that is inputted by a first user and corresponds to presentation unit information for designating a presentation unit for presenting a tactile stimulus by a tactile presentation device and mode information for designating a mode of the tactile stimulus; a generation unit (218) configured to generate a tactile control signal for presenting the tactile stimulus to the presentation unit in accordance with the control command; and a first distribution unit (222) configured to distribute the tactile control signal to the tactile presentation device worn on a body of a second user, in which the tactile control signal corresponds to at least one of a presentation timing, frequency, interval, waveform, presentation time, and intensity of the tactile stimulus.

An object is to provide an image display device capable of correcting a position in a simple manner even when a deviation occurs in position alignment in accordance with movement of a user. The image display device 100 includes a correction processing unit 102 that corrects a deviation when the deviation occurs between image data G and a steel frame T in a field of vision of a user U that occurs in accordance with movement of the user. This correction processing unit 102 acquires a coordinates correction position S that becomes a reference position used for a correction process from the steel frame T1 or the like that is a partial member using design data stored by a storage unit 103 and a self-position of the user U with respect to the steel frame T. The correction processing unit 102 performs correction by performing position alignment of the image data G on the basis of the one coordinates correction position S.

A 3D calling system can provide 3D calls in various modes according to transitions and can provide affordances (i.e., visual or auditory cues) to improve 3D call image capturing. The 3D calling system of a recipient in a 3D call can display a hologram (from images captured by an external capture device (ECD)) or avatar of a sending call participant in a variety of ways, such as by making them “world-locked,” “ECD-locked,” or “body-locked.” The selection of a 3D call mode can be based on factors such as whether an ECD is active, whether the ECD is in motion, and user selections. In various cases, the 3D calling system can trigger various affordances to improve the quality of the images captured by the sender’s ECD, such as a displayed virtual object and/or an auditory cue, either signaling to the user that a current ECD configuration is non-optimal and/or providing instructions for an improved ECD configuration.
