SpaceMousE® is a 3D mouse that can improve ergonomics and the efficiency of drawing and design. The traditional mouse is an important part of all 2D / 3D CAD graphics workstations. Lightweight and easy to operate. However, from an ergonomic point of view, it has an obvious shortcoming-you always need to operate it with the same hand to complete all tasks. When the mouse is widely used for repetitive operations, this can cause pain and mouse hands, also known as RSI (Repetitive Strain Injury). Using a 3D mouse can prevent these symptoms and make your CAD workflow more efficient and healthier.
