Abstract: A task appropriateness determination apparatus includes a first learning unit causing artificial intelligence (AI) to learn image information of an index indicating a target object in a task appropriately completed state, an appropriate image provider providing an image possibly including the target object in the appropriately completed state and the index, a second learning unit causing the AI to detect an image where the index is present from the provided image after learning of the index, and learn image information of the target object in the image where the index is present, an image capturing unit capturing an image of a region including the target object and the index at least after the task, and a task appropriateness determiner determining that the task has been appropriately performed in response to detection by the AI of the target object roughly identical to the learned target object in the appropriately completed state.

Abstract: An operation-correctness determining apparatus capable of determining whether a predetermined operation has been performed correctly includes a wearable camera, a target object detector, a hand skeleton detector, a motion detector, and an operation-correctness determiner. The wearable camera captures a region larger than or substantially equal to an operator's field of view. The target object detector detects a target object within a captured region captured by the wearable camera. The hand skeleton detector detects an operator's hand skeleton within the captured region. The motion detector detects an operator's hand behavior from time series variation of the detected target object and from time series variation of the detected operator's hand skeleton.
