Abstract: An information processing apparatus 100 acquires, when an actual performance by an athlete is started, an element that has already been performed and a score of the element that has already been performed in the actual performance, based on data acquired in real time. The information processing apparatus 100 estimates an element with a high probability of being performed hereafter in the actual performance, based on at least one of the planned performance information and the data. The information processing apparatus 100 estimates an estimated score of the actual performance being performed, based on the score of the element that has already been performed and an estimated score in the case in which estimated elements that have not been performed succeed, and generates screen information to display the estimated score of planned performance and the estimated score of the actual performance.

Abstract: A video reproduction apparatus determines a position of a joint of a performer based on a sensing result by a sensor. The video reproduction apparatus calculates an angle formed by a joint used for scoring an element of an athletic event by using calculation information regarding a calculation formula for calculating the angle and the determined position of the joint of the performer. The video reproduction apparatus displays a performance image of the performer acquired from a camera and a scoring image having the angle displayed on a 3D model image of the performer which is generated according to the sensing result so as to be compared with each other.

Abstract: A generation device includes a memory, and a processor coupled to the memory and configured to receive first performance composition including a plurality of skills, refer to load information representing a load on each body part when a skill is performed and calculate a load value indicating a total of the load applied to a performer who performs the first performance composition, refer to scoring rules that stipulate scores based on difficulty of skills and calculate a performance score indicating a total of scores of the plurality of skills included in the first performance composition, and based on the load information and the scoring rules, generate second performance composition according to performance rules that stipulate composition of the skills, the second performance composition leading to a score higher than the performance score and reducing the load value.

Abstract: A non-transitory computer-readable recording medium having stored therein a video generation program for causing a computer to execute a process comprising: tracking a position of a three-dimensional model of each of a plurality of subjects in a three-dimensional space generated by combining, for the subjects, a plurality of imaging frames captured by a plurality of cameras in a plurality of directions; obtaining positional information of the subjects included in the three-dimensional space; obtaining information related to the subjects; and generating synthesized video by combining the information related to the subjects with a background area near the subjects based on the positional information of the subjects among areas of free viewpoint video generated on the basis of the three-dimensional model of each of the subjects.

Abstract: A marking assist device includes a memory, a storage that stores an image that records a competition in which a player performs a plurality of skills in a time sequence, and a processor coupled to the memory and configured to acquire a first marking result and a second marking result, the first marking result being marking of each of the plurality of skills based on sensor data on the performing player, the second marking result being inputted by a referee, display first discriminators of the skills included in the first marking result and second discriminators of the skills included in the second marking result while associating the first discriminator with the second discriminator, and when any discriminator is selected from the displayed discriminators, identify a video associated with selected discriminator from the images and displays the identified video.

Abstract: A practice assist device (100) specifies a plurality of first frames respectively representing a plurality of scenes constituting a first skill from first sensing data measured by a sensor during a performance of the first skill. The practice assist device (100) specifies a plurality of second frames respectively representing the scenes constituting the first skill from second sensing data measured during another performance of the first skill. The practice assist device (100) displays, for at least one of the scenes, the first frames and the second frames in association with each other.

Abstract: A display method executed by a processor includes: acquiring a recognition result of a plurality of elements included in a series of exercise that have been recognized based on 3D sensing data for which the series of exercise by a competitor in a scoring competition is sensed and element dictionary data in which characteristics of elements in the scoring competition are defined; identifying, based on the recognition result of the elements, a displayed element in a 3D model video corresponding to the series of exercise based on the 3D sensing data; determining a part of options to be a subject of display, in accordance with the displayed element, out of a plurality of options corresponding to a plurality of evaluation indexes concerning scoring of the scoring competition; and displaying the part of options in a mode to be selectable.
