The technology was developed in collaboration with Mr. Kajiro Watanabe, president of laboratory detection and control of a professor at Hosei University in Japan. In the first commercialization of this technology, “etga Swing Lesson,” is a mobile application that analyzes the changes in golf under the guidance of professional golfer Mr. Tadashi Ezure.

Mobile phone use embedded sensors, the application meets the motion data, which are then put into motion a 3D detection engine to analyze and evaluate the trajectory of the golf swing the user and provide advice based on principles of golf professional golfer Sr . Tadashi Ezure’s. It also allows users to compare each blow against their recent changes of the best recorded, which is a complete program of leading swing diagnosis. In addition, the application can connect to a range of online services related to mobile, including a variety of services provided by Golf Digest Online Inc.

The golf swing analyzer-engine incorporates a 3D motion detection that measures the inclination and rotation of the waist for a fixed period of time. Pick up the discrepancies in each movement pattern, and detects the distinctive aspects of these models to analyze user movement pattern. This technology was developed jointly with Mr. Kajiro Watanabe, who is chairman of laboratory detection of Control Co., Ltd. and a professor at Hosei University in Japan.

By applying this algorithm to patterns of movement in the golf shots, which can detect the shape of a user and select the distinctive features in each swing for the diagnosis of the areas the user needs to improve.

Overview of “Lesson etga Swing”
