Abstract: A motion learning support apparatus displays a teaching-aid video segment and a segment of practice video of a learner alternately on a monitor, the practice video being of the learner who is imitating a motion of the teaching-aid video segment and being taken with an imaging unit. The motion learning support apparatus includes: motion detection unit to detect a motion of the learner and a motion information acquisition unit; an evaluation unit to evaluate similarity of a motion of the learner to a motion in the teaching-aid video segment; and first learning support processing unit to, when the evaluation unit evaluates that the motions are similar, switch the monitor from video taken with the imaging unit to a following teaching-aid video segment. Thereby, vividness of an image due to the illusion effect induced to the learner can be improved, and so the learning effect can be improved for supporting.

Abstract: A trochoid propulsion system includes wheels provided at three points of the outer edge of an outer wheel part that turns around a driving shaft; and a steering link part that co-rotates with the action part and is movable horizontally on a turning plane. The steering link part includes a liner slider including a guide member attached to a vertical steering shaft that rotates each wheel so that the length direction is in a radial direction of the steering shaft and a moving member that slides on the guide member.

Abstract: According to the method and apparatus, light beams directed toward virtual visual points are detected from among light beams emitted from or reflected on the surface of an object. The detection is effected by an image pickup device in a plurality of positions lying on a virtual closed surface with which the object is enclosed. The detected light beams are converted into image pickup signals, which are delivered to a display device adapted to display an image toward a visual point of an observer standing or sitting in a place different from a place where any of the virtual visual points is disposed. The image is displayed in such a manner as if light beams were emitted toward the visual point of the observer from various points on the surface of a virtual object disposed in a virtual position corresponding to the relative positions of the real object and any of the virtual visual points.

Abstract: A projector is disposed at a position that is optically conjugated to a position of eyes of an observer. The projector projects an image to a screen that has retroreflection function so as to provide information of virtual space to the observer. If a real object such as a tactile sense provision device that is to be shielded by the virtual space exists, a part or the whole of the real object is optically hidden from the projection of the projector by a shielding member having retroreflection function, for example, by placing a shielding screen on which a retroreflection material is coated, or by coating the retroreflection material.
