1) Keyboard labels- Some students have trouble using a typical keyboard because they cannot see the letters, numbers, and symbols on the keys. You can put self-adhesive keyboard labels on the standard keyboard in order to meet an individual's needs.
2) Selecting/Pointing Devices- It may be difficult for students with physical disabilities to isolate a finger or use their hands to press a single key on a typical keyboard. Selecting/pointing devices can help. These devices can be controlled by movements of the hand, arm, head, or foot.
3) Keyguards- Acrylic or metal covers with holes that are put on top of the keyboard. There is one hole for each of the keys. Keyguards increase typing accuracy because the holes only let one key at a time to be pressed. This helps students with poor fine motor control.
4) Moisture Guards- Are also called keyboard protectors or keyboard skins. They are flexible covers that fit over the keyboard to protect it from moisture, dirt, dust, or other harmful substances. Moisture guards may help students who drool or tend to spill or drop items.
