Abstract: Provided are an inspection method, a program, and an inspection system capable of improving accuracy of inspecting a color of a surface of an object. The inspection method includes acquisition step and comparison step. Acquisition step is a step of acquiring a target image of a surface of an object obtained by an imaging system imaging the surface of the object illuminated by an illumination system. Comparison step, is a step of comparing a color of an attention region on the target image with a color of a reference region. The reference region is a region of a reference image of a surface of a reference object as a reference of a color of the object, and a region corresponding to a combination of an incident angle of light from the illumination system and a reflection angle of light to the imaging system in the attention region.

Abstract: A learning assistance device for a user to perform a learning task includes: a first concentration level estimator that estimates a first concentration level of the user, by analyzing information from an image capturing section that captures an image of a user; a second concentration level estimator that estimates a second concentration level of the user, by analyzing information which the user has actively input when performing a learning task; and a presentation switching section that switches between learning task content and between presentation schemes, based on at least one of the first concentration level or the second concentration level.
