The "EX-G" series is a gripless mouse developed in collaboration with an orthopedic surgeon that can be used with a natural hand shape. It is a Bluetooth(R) 5-button mouse that focuses on the muscles that move the wrist and fingers, minimizing the strain on the body when moving the mouse.
"EX-G" is a 5-button mouse developed in collaboration with doctors to provide the ultimate grip.
With the cooperation of Dr. Ichiro Miyagawa, director of Narashinodai Orthopedic Surgery and Internal Medicine, we focused on the "brachioradialis muscle," which moves the wrist, and the "extensor digitorum communis," which moves the fingers, to pursue an angle and shape that is suitable for the hand muscles that move the mouse.
You can use it simply by placing your hand naturally on it, so no extra force is required and the strain on both your wrists and fingers is minimized.
To achieve the "comfort that makes it feel like you're not even holding it in your hand," we've adopted a design with rounded corners and no visible seams. We also aimed for an even more evolved grip, with buttons that are easy to access and a seamless feel to the operation.
