Abstract: A display method includes generating first analysis information related to at least one of a ball shooting direction and a ball curving form swing on the basis of a plurality of pieces of data related to a plurality of swings, output from an inertial sensor which is attached to a user or an exercise appliance swung by the user and measures the plurality of swings performed by the user, and generating a first region image on the basis of the first analysis information, in which the first region image includes a plurality of time-series region images, and the plurality of time-series region images are displayed in a coordinate system having at least two indexes as axes.

Abstract: A display method includes generating first analysis information on the basis of a plurality of pieces of data related to a plurality of swings, output from an inertial sensor which is attached to a user or an exercise appliance swung by the user and measures the plurality of swings performed by the user, estimating respective ball arrival positions corresponding to the plurality of swings on the basis of the first analysis information, and displaying a first region image in a coordinate system having at least two indexes as axes on the basis of the respective ball arrival positions.

Abstract: A motion analysis method includes calculating a level of a swing using an output from an inertial sensor measuring the swing of exercise equipment on the basis of a relationship between a first angle formed between a tangential direction of a swing trajectory of a ball hitting portion of the exercise equipment at impact and a target hitting direction, and a second angle formed between a direction orthogonal to a hitting surface of the ball hitting portion at the impact and the target hitting direction.

Abstract: A defect of a process based on an operation which is performed across the inside and outside of a display region on which a projected image is displayed is eliminated. Provided is a projector including detection unit for repeatedly detecting a position indicated by an indicator with respect to a screen which is a projection screen onto which an image is projected, and supplying position information of the detected position; and generation unit for generating position information of a third position located between a first position within a primary screen which is a display region of the image and a second position outside the primary screen, in a case where the detection unit detects the first position, and then detects the second position.
