Ergonomic Considerations

You will be using your C1 PictureBook Computer as a portable device in a variety of environments. Whenever possible, you should attempt to apply the following ergonomic considerations to both stationary and portable environments.

Computer positioned directly in front of you

Arms at desk level

Wrists relaxed and flat

Position of your computer – Place the computer directly in front of you as you work. Keep your forearms horizontal, with your wrists in a natural, comfortable position while using the keyboard, pointing device, or external mouse. Let your upper arms hang naturally at your sides. Take breaks during sessions with your computer. Excessive use of the computer may strain muscles or tendons.
