What is it?
A trackball is an alternative input device that functions like a mouse but uses a stationary base and a rolling ball to control the cursor. Unlike a traditional mouse that requires movement across a surface, users operate a trackball by rotating the ball with their fingers, hand, or other body parts. In the inclusive classroom, trackballs are especially helpful for students with physical disabilities, limited motor control, or coordination challenges, as they require less movement and can be more accessible.
How to use it?
To use a trackball, the device is connected to a computer or tablet, typically via USB or Bluetooth. The student moves the on-screen cursor by rolling the ball and uses built-in buttons or external switches to click, drag, or scroll. Some trackballs can be customized with larger balls, adjustable sensitivity, or external switch access, allowing for precise and personalized control. Teachers can support students by adjusting settings and offering guidance on how to build familiarity and confidence with the device.
Why use it?
Trackballs support accessibility and independence for students who have difficulty using a standard mouse due to motor limitations, fatigue, or positioning needs. They provide a stable, efficient way to interact with digital content, helping students participate in writing, research, communication, and other classroom activities. By offering tools like trackballs, educators create inclusive learning environments where all students can engage with technology in ways that work best for their bodies and abilities.
