JumpEye 4+

JUMP EYE

The macOS version supports only loading videos.

The slow videos saved in camera roll will be edited to normal speed instead of slow speed at the beginning and the end. If you load the video as it is, JumpEye will not be able to measure the video accurately because the playback speed at the beginning and end of the video will not be slowed down.

To fix this issue, go to the Photos app, select the video you want to import and tap the Edit button in the upper right corner of the playback screen.
The barcode-shaped white lines displayed at the bottom of the video on the edit screen will be narrower at the left and right edges than at the center.
By widening the spacing between the rightmost and leftmost white lines, you can slow down the playback speed of all of your videos.
After editing, please load the video in JumpEye for measurement.

In addition, if you can not start the camera application in JumpEye, please open the settings application and search "JumpEye" in the search window.
Tap "JumpEye" in the search results, you will go to the JumpEye privacy settings screen.
After that, please give permission for photo, microphone and camera.

□Outline□ JumpEye is an application made to calculate the jump height from the jump time. By sending the slow motion video taken with the high-speed camera on the iPhone frame by frame, and selecting the frame of the takeoff and landing, it calculates the dwell time and automatically calculates the leaping height.

How to use □ 1. open the app and focus on the athlete's foot. 2. 2. take a video of the vertical jump in slow motion or import a video from your photo library. 3. playback the video and manually select the jump time. Play the video, manually scroll through the frames, find the moment of release and landing and press "Start" and "Stop". 4. The jumping height will be calculated automatically from the jumping time.

The video opened in the app will be automatically saved with the title (hour:minute:second), and you can rename or delete the video by pressing and holding the title. The title will be automatically added with the leap height. You can also import videos from your camera roll. Manual focus function to clearly detect the ground and the grounding. Three frame advance functions (slide, 10-frame advance, 1-frame advance) help you find the ground and release frame quickly. Zoom function. The RJIndex can be calculated by taking a picture of a rebound jump of five times.

Note: The calculation of jump height is based on the assumption that the height of the body center of gravity is the same at the time of landing as at the time of taking off. Therefore, there is a possibility of overestimation by bending the leg at the time of landing.
