JUMP EYE □General Information□ JUMP EYE has been developed to calculate the vertical jump height by using the flight time. Use your iPhone's high-speed camera to measure the flight time during a vertical jump. □Procedure□ 1. Open JUMP EYE and adjust the camera’s focus on an athlete's feet. 2. Simply record videos of a vertical jump using Slo-Mo (120/240 fps) or import the ones you want from the Photo Library. 3. Once we playback the video, we have to then manually go through frame by frame to identify and mark the takeoff and landing frames (press “start” and “stop”). 4. The formula then automatically calculates the duration of the flight and the jump height. □Main characteristics□ ・Videos are given an automatic file name (hh:mm:ss), which can be edited by holding down on the icon for one second, then we can rename or delete the file. ・After marking the frames, the jump height is automatically labelled after the file name. ・You can also import movies from the Photo Library. ・Manual focus makes feet and floor easily identifiable and precise. ・You can playback the movie in 3 ways (manual slider, frame by frame, and 10 frame mode). ・The pinch-to-zoom feature is available. ・The Rebound Jump Index (RJI) can be calculated by continuous jumping (press “RJindex”). □Note□ The equation to calculate jump height is justified only if the center of mass height is the same at takeoff and landing. Therefore, if you land on the ground in a crouched position, your jump height will be overestimated. □概要□ JUMP EYEは跳躍時間から跳躍高を計算するために作られたアプリです。 iPhoneでのハイスピードカメラで撮影したスローモーション動画をコマ送りし、離地、接地のコマを選択することで、滞空時間を計算し、自動的に跳躍高を算出します。 □方法□ 1. アプリを開き、選手の足にフォーカスを合わせます。 2. 垂直跳びをスローモーション機能で撮影、もしくはフォトライブラリから動画を読み込みます。 3. 動画を再生し、手動でコマ送りをし、離地と接地の瞬間を見つけ、「スタート」と「ストップ」を押します。 4. 跳躍時間から自動で跳躍高を計算します。 □主な機能□ ・アプリで開いた動画は自動的に(時:分:秒)というタイトルで保存され、長押しすることによって名前の変更、動画の削除をすることができます。 ・タイトルに跳躍高が自動的に付きます。 ・カメラロール内の動画も取り込みも可能です。 ・マニュアルフォーカス機能により、接地と離地をはっきりと検出できます。 ・3つのコマ送り機能(スライド、10コマ送り、1コマ送り)により、素早く接地と離地のコマを見つけることができます。 ・ズーム機能が付いています。 ・5回跳躍のリバウンドジャンプを撮影することでRJIndexも算出可能です □注意□ 跳躍高計算は、「離地時と接地時の身体重心高が同じ」という仮定で行っています。したがって、着地時に足を曲げたりすることによって過大評価する可能性があります。
