Fujitsu and Lapis Semiconductor Improve Windsurfing Skills with IoT

By Neha Rastogi May 11, 2017

The Japan Windsurfing Association, Fujitsu Limited, and Lapis Semiconductor Co., Ltd. have announced to start the IoT-based field trials in order to help windsurfers improve their sailing skills. The trials will begin on May 11 and will continue till September 30, 2017. For the trials, Lapis Semiconductor has developed a device that can simultaneously record GPS and sensor data across nine-axes sensor data from an accelerometer, gyrometer, and geomagnetic sensor unit. 
 
For the first time in windsurfing, the technology will help in using data to understand sail handling. This would allow competitors to compare their data with those with higher ranks, thereby enabling in discovering ways to improve their sailing skills by looking at differences in handling 3D models and numerical values.

Working of the System 
 
1. Understanding Sail Handling
 
A miniature sensor node device is attached to the sail, which simultaneously records both the angles of sail movement and the speed and course of the board, and uploads that data to the cloud. The cloud data will be subjected to an analysis, eliminating the influence (vibration noise) of things like waves, using an attitude estimation algorithm (also used in attitude control for robots and drones) calculating accurate angles. 
 
This enables comparisons between sail movement at various times in the context of the speed and direction of the board. Going forward, if it were thought necessary to collect other data, such as the body position of the competitor, during the course of the field trial, integrated data analysis could easily be done just by adding sensors.
 
2. Effective Training through Visualizations
 
The analyzed data can be checked by switching between varieties of display formats, including 3D models, numeric values, graphs, and oceanic maps. Competitors can objectively evaluate their sailing ability through the movements of 3D models and numerical values, and compare their data with that obtained from higher-ranked competitors.
 
Organizations’ Roles
 
Japan Windsurfing Association
 
It will provide space for the field trials and recruit competitors for participation, promoting and evaluating its use in the improvement of sailing skills of the competitors. It will also undertake promotional activities to raise the level of Japanese windsurfing and expand the number of people competing. 
 
Fujitsu
 
It will analyse different types of sensor data collected in the cloud by providing an application that will analyse and display it as meaningful data. The application will visualize this data in 3D models and graphs, thereby supporting improvements in windsurfing technique.
 
Lapis Semiconductor
 
It has developed the WindHack and WindHack Pro sensor boards for use in this field trial. This would improve windsurfing technique, using the Lazurite IoT reference design.
