Abstract: An information output apparatus according to an embodiment includes: first estimation means for estimating an attribute indicating a feature unique to a user, based on video data; second estimation means for estimating a current action state of the user, based on face orientation data and position data of the user; determination means for, in an action-merit table that defines combinations each composed of an action for inducing a user to use a service according to an attribute and a state, and a value indicating a magnitude of a merit of the action, determining an action for inducing the user to use a service with a high value indicating the magnitude of the merit of the action, out of combinations corresponding to the estimated attribute and state; setting means for setting a reward value for the action, based on action states estimated; setting means for setting a reward value for the action, based on action states estimated before and after the action; and update means for updating the value of the action

Abstract: An in-pipe work device comprising at least two movement mechanisms connected with each other in a longitudinal direction of a pipe by a flexible tube, and a control device for controlling the movement mechanisms, the movement mechanisms including a body connected to the flexible tube, a guide member installed on the body such that the guide member is slidable in an axial direction, a support leg drive mechanism provided on the guide member and having a support leg movable in a radial direction of the pipe, for pressing the support leg against an inner wall of the pipe, thereby to hold the guide member kept unmovable in an axis direction of the pipe, a slide mechanism for relatively sliding the guide member and the body, with the support leg pressed against the inner wall of the pipe, thereby to slide the body in the axis direction of the pipe, wherein the control device controls the in-pipe movement device so as to move in a pipe by itself, by sequentially operating the plurality of movement mechanism in a pr
