When we are working hard to practice golf swing, we can't see our swing. Are we doing it right? Are our swing what we imagined? If we can see our swing, it will obviously be very beneficial for swing practice. This is the so-called practice with feedback. Practice with feedback can prevent us from repeating wrong swing over and over again and forming memories of wrong swing. Applicable to golf coaches: CaseVision Golf Swing Replay and Analysis APP can help coaches teach golf more efficiently. The coach can explain and analyze the student's swing just now for the student on the spot, which makes it easy to reach a consensus. Then the coach tells the student how to correct it, and the student practices according to the coach's instructions. With the support of CaseVision Golf Swing Replay and Analysis APP, players and coaches can check whether each swing meets the coach's intention. Through this closed-loop feedback guidance practice, the efficiency of golf swing teaching and learning will be greatly improved. Applicable to players: CaseVision Golf Swing Replay and Analysis APP is very useful for players to correct and optimize their swing. Before muscle memory is formed, it is difficult for us to control our swing in accordance with our consciousness. When a player cannot see his own swing, he does not know that his so-called corrective actions are basically repeating his original wrong actions. At this time, he needs to see his swing the most. Every time he swings, the instant playback and reference line will give him intuitive feedback on the status of each swing. By practicing and optimizing the corrective actions in this closed-loop feedback way, I believe that the player will soon correct his swing problems and form muscle memory, and will not go further and further on the wrong track. CaseVision Golf Swing Replay and Analysis APP provides the following functions to allow users to quickly and conveniently see the swing details they want to see and achieve accurate and fast feedback: (1) The software automatically detects and records the swing action without any other sensor devices. Therefore, it is very convenient to use. Supports front and side shooting. (2) Timely playback of videos: You can play at different speeds, or drag and drop to quickly reach the position you want to see. (3) Automatically identify key positions: preparation, take-off, backswing, top, downswing, release, impact, follow-through, forward swing, and finish. Players can watch pictures of key positions instead of videos, or choose to watch pictures of a key position (such as the top of the backswing). In this way, the screen will automatically display pictures of the selected position (such as the top of the backswing) or pictures of all key positions for each swing, so as to achieve quick feedback. It saves players time and does not affect the swing rhythm. (4) Intelligent line drawing: This function completely puts an end to the tedious, time-consuming and inaccurate manual line drawing. Players can choose to draw the head position, spine line, shoulder line, hip line, knee line, hand position, body side line, arm line, leg line, arm line, balance line, and club head path by clicking. Players can analyze and evaluate the swing based on these reference lines. (5) Intelligent drawing of the swing plane. The swing plane can be automatically drawn and display for each swing, providing the player with feedback on the swing plane, so that they can practice a stable and scientific swing plane, which is the core framework for stable, accurate and efficient swing. (6) Recording and storage of swing videos. This facilitates comparative analysis of the training process.
