Abstract: Provided is a method of obtaining state data indicating a state of a user. The method includes: obtaining estimation models for obtaining pieces of state data existing in a plurality of layers from sensor data obtained by a sensor; obtaining at least one piece of sensor data; obtaining state data of a lower layer from the at least one piece of sensor data, based on the estimation models; and obtaining state data of a higher layer from the state data of the lower layer, based on the estimation models.

Abstract: An image display apparatus that automatically adjust a pointing direction of a remote controller to almost match with a position of a pointer on a screen, and a pointing method performed by the image display apparatus are provided. The image display apparatus includes a reference angle detector configured to detect a reference angle formed by the pointing direction of the remote controller with respect to a reference direction set for a display; a remote control direction detector configured to detect a remote control direction which is a direction in which the remote controller is viewed, from a reference point set on the display; and a standard direction adjuster configured to adjust a standard direction set in the remote controller so that the standard direction reaches the reference point on the display as viewed from the remote controller, based on the reference angle and the remote control direction.

Abstract: A dose distribution measurement device includes at least two cameras arranged on a plane perpendicular to the center axis of irradiation of a water phantom with a particle beam so as to take an image of light emission of a fluorescent substance containing liquid in the water phantom and a dose distribution calculation and evaluation unit having a spot position determination part for determining, from data of the camera image taken with the cameras, the position of a spot Irradiated with the particle beam during its staying and a dose addition part for calculating an irradiation dose distribution at the spot position determined by the spot position determination part using a PDD and an OCR stored in a pencil-beam dose-distribution data storage part, to add the irradiation dose distribution at each of spot positions.
