  • Publication number: 20180232193
    Abstract: A presentation system is described herein. The system can include a room for playing a scene and can be made up of a collection of displays. The system can also include media players to manage the playing of content on a corresponding display of the collection of displays. The system can also include a server to distribute objects to the media players. The scene can include the objects, which may be selectively played on the displays when the scene is played on the room. The media players can receive the objects and can determine whether the objects are intended to be played on the corresponding displays as part of the scene to be played. If so, the objects can be rendered on the corresponding displays on which the objects are intended to be played, which can bypass the rendering of the scene as a whole by the system.

  • Patent number: 9990088
    Abstract: Evaluation values regarding a change in velocity of an object at coordinates of a detection surface are calculated on the basis of a series of coordinate data of the same object, and it is determined whether there is an error in each coordinate data on the basis of the evaluation values. In a case in which an extreme change in a velocity of the object occurs due to an influence of noise or the like, it is possible to accurately determine an error of the coordinate data on the basis of the evaluation values. Since the coordinate data in which it is determined that there is an error is corrected with data indicating the same coordinate P as that of coordinate data immediately before such coordinate data, the error of the detection result of the coordinates can be effectively reduced.

  • Patent number: 9836175
    Abstract: A series of degree-of-approach data of the same object generated over a plurality of cycles of a detection operation is averaged in filter processing of the filter processing unit, and accordingly, the degree-of-approach data after averaging is acquired. Therefore, even in a case in which the degree-of-approach data is temporarily greatly changed due to an influence of noise, such a temporary change in the degree-of-approach data after averaging is suppressed. Further, response characteristics of a filter in the filter processing of the filter unit are changed according to a noise level which is detected by a noise detection unit. Accordingly, since appropriate filter processing according to the noise level is performed on the degree-of-approach data, the degree-of-approach data in which the influence of noise is effectively reduced is obtained.

  • Publication number: 20160147373
    Abstract: A degree of approach of an object in positions of a detection surface is periodically detected by a sensor unit, a group of detection data items indicating a result of the detection is generated in every one of cycles. The group of detection data items generated in the sensor unit is acquired in every one of cycles by a detection data acquisition unit. In the error determination unit, it is determined in every one of cycles whether there is an error in the detection operation due to noise based on a degree of a temporal change and a degree of a positional change in the detection data. When it is determined by the error determination unit that there is an error in the detection operation of one cycle, a process of acquiring the detection data generated in the one cycle is skipped in the detection data acquisition unit.
