Visualizing hand movements underwater to support stroke improvement without relying on feel Palm orientation Full stroke trajectory Left-right power difference eo SwimBETTER is a wearable device that, when worn while swimming, visualizes data such as changes in palm orientation underwater, the direction of force applied to the water, propulsion trends, full stroke trajectory, and left-right power differences. Due to the unique underwater environment, swimming has been considered more difficult than land or cycling sports to objectively grasp the forces applied and changes in form during movement. eo SwimBETTER complements the analysis of swimming, which has largely relied on the feel of coaches and athletes, with data, enabling clearer and earlier identification of issues and more efficient training. The acquired swim data can be instantly confirmed and analyzed on the spot via a dedicated app or platform, and can be used for athletes' self-reflection, coaching guidance, team data sharing, and efficient improvement of training plans.
