A compact and portable trackball is an excellent stationary pointing device for limited desktop space. Unlike traditional mice that require movement across a surface, a trackball remains stationary while you control the cursor by rotating the ball with your fingers. This design allows for precise control without needing much room, making it ideal for small workspaces. Additionally, many trackballs come with customizable buttons for added functionality.
