Abstract: A position analysis device includes: an input interface that acquires the captured image obtained by the camera; a processor that calculates coordinate transformation from a first coordinate system to a second coordinate system with respect to the target position in the acquired captured image; and a memory that stores a correction model to generate a correction amount of a position in the second coordinate system, wherein the processor corrects a transformed position from the target position, based on the correction model including weight functions corresponding to reference positions, the transformed position being a position obtained by the coordinate transformation on the target position in the first coordinate system to the second coordinate system, the weight functions each producing a larger weighting in the correction amount as the transformed position is closer to a corresponding reference position, the reference positions being different from each other in the second coordinate system.

Abstract: An image analysis device comprising: an input interface to acquire image data indicating an image of an operator performing task; and a controller to detect the task performed by the operator sequentially, based on the image data, to generate task detection information indicating a detection result of the task, wherein the task includes a plurality of processes performed by the operator, and the controller compensates the task detection information by interpolating a detection result of the task within an undetected period, in accordance with a pre process and/or a post process of the undetected period, the undetected period being a period in which the task is not detected, the pre process being a process of the task detected previously to the undetected period, and the post process being a process of the task detected subsequently to the undetected period.

Abstract: The present disclosure provides a head-mounted display that achieves smooth communication that allows a wearer of the head-mounted display and an outside person to understand their intentions with each other, and a control method of controlling the head-mounted display. Head-mounted display includes: sound receiver that receives a sound coming from a specific direction; voice detector that detects a voice from the sound received by sound receiver; head movement detector that detects movement of the head of the wearer of head-mounted display; external display that displays externally visible information; and response detector that, when voice detector detects the voice, and head movement detector detects movement of the head of the wearer facing toward the specific direction, displays information indicating that the wearer has responded to the voice on external display.
