Fujitsu Ltd developed a sensing technology that can detect three-dimensional movements of a human body based on information from sensors embedded in a mobile phone.

Fujitsu developed the technology in collaboration with Kajiro Watanabe, president of Sensing Control Lab and professor at Hosei University. Also, the company announced the application software "ETGA Swing Lesson," which can check golf swing with a mobile phone.

Fujitsu plans to offer an opportunity to experience the application at CEATEC JAPAN 2009, which will run from Oct 6 to 10, 2009, at Makuhari Messe in Chiba Prefecture, Japan.

The company found that the quantity of rotational motion in a given amount of time and the direction of the waist differ for each movement pattern. And it developed a technology to analyze movement patterns by detecting feature points.

Fujitsu used this algorithm to detect movement patterns of golf swing and analyze a swing form by detecting feature points for each swing.

To use ETGA Swing Lesson, a mobile phone in a carrying case is attached to the waist. It is possible to conduct a measurement and show advice on a swing form by touch operations while following the guidance displayed on screen.
