If we recommend a trackball for an employee, the specific model we recommend depends on his/her hand size and the type of work he/she is doing.
Many trackballs are ambidexterous and can be used with either hand. In most cases, trackballs with a ball in the center rather than the side are recommended in order to minimize the risk of thumb tendonitis. Below are examples of a few ambidexterous trackballs.
To maintain the trackball’s speed, it is recommended to occasionally take out the ball and clean the dust out of the pocket beneath it with a soft cloth.
There are four main things to know when using a trackball.
- Relax the arm.
- Rest the hand.
- Use the middle three fingers on the trackball, not just one finger.
- Make sure no awkward postures are taken.
