Arthritis – Using an Eye Tracker as computer input

Arthritis can make it painful to control a computer with a mouse, due to the repetitive nature of the hand movements. In this case using an eye tracker as an input device can make your life more comfortable. There are several forms of arthritis that have an impact on the pain levels associated with controlling a computer with a mouse.

Arthritis hand

Rheumatoid Arthritis

People affected: 0.5 to 1.0% of the adult population.

This is a chronic inflammatory disorder that can affect more than just your joints. It typically results in painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with RA can severely limit hand and finger mobility.



People affected: 13% of the adult population

This is the most common form of arthritis. It’s a wear-and-tear condition that occurs when the protective cartilage that cushions the ends of your bones wears down over time. If it affects the hands, it can make fine movements, like using a mouse, difficult and painful.


Psoriatic Arthritis

People affected: 0.6 to 0.9% of the adult population

This form of arthritis affects some people who have psoriasis. It can cause joints to become swollen, stiff and painful. When it affects the hands, it can interfere with fine motor skills.



People affected: 1 to 4% of the adult population

Gout is a common type of inflammatory arthritis that is caused by high levels of uric acid in the blood. The uric acid can form needle-like crystals in a joint and cause sudden, severe episodes of pain, tenderness, redness, warmth, and swelling. An acute gout attack in the hand can make using a mouse very painful.
