Abstract: An image analysis device including: an input interface to acquire image data indicating a captured image of a site in which a plurality of operators performs a plurality of tasks; a controller to generate, based on the image data, task history information indicating the tasks performed in the site by respective operators; and a storage to store the task history information, the controller successively recognizes the tasks and positions of the operators, based on the image data at each time in the site; and detects crossing caused between a plurality of trajectories each including successive positions for each of the operators; generates the task history information associating tasks recognized at each time with the respective operators, based on the trajectories, when the crossing is not detected; and associates the recognized tasks with the respective operators, based on the recognized tasks and past task history information, when the crossing is detected.

Abstract: An object detection device for detecting a position of an object on an imaging plane imaged by a camera, including: a processor to acquire image data generated by the camera and perform coordinate transformation, with respect to a position of the object, from first coordinates associated with an image indicated by the image data to second coordinates associated with the imaging plane; and a memory to store setting information used for the coordinate transformation, wherein the setting information includes a set value indicating a height from the imaging plane for each type among a plurality of types of objects, and the processor acquires a position of the object in the first coordinates and a type of the object based on the image data and calculates a position of the object in the second coordinates by performing the coordinate transformation using the set value corresponding to the type of the object.

Abstract: A method evaluating a decrease in production performance for a target work. A work efficiency evaluation method includes the steps of: reading, from a storage, model data used for evaluating work efficiency and generated based on operation data related to work including a predetermined work time and a predetermined work amount; calculating an degree of impact of a decrease in work efficiency on the basis of data related to time required for work and a work amount by the model data; and evaluating a decrease in production performance in accordance with the degree of impact.

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.
