Motor Impairments Simulation
Motor impairments affect a person's ability to control their movements and can range from mild tremors to complete paralysis. Approximately 13.7% of US adults have a mobility-related disability, affecting over 20 million people.
Common Motor Impairments:
- Parkinson's disease - Affects 10 million worldwide, causes tremors and slow movement
- Arthritis - Affects 54 million US adults, causes joint pain and stiffness
- Cerebral palsy - Affects 764,000 people in the US, impacts movement and posture
- Spinal cord injuries - 291,000 Americans live with SCI, may cause paralysis
- Amputations - 2 million Americans live with limb loss
Challenges users face include:
- Precise targeting - Difficulty clicking small buttons or links
- Tremors - Involuntary movements that affect accuracy
- Limited range of motion - Difficulty reaching all areas of the screen
- Fatigue - Tasks take more energy and time to complete
- Slow response times - Need more time to process and react
Assistive technologies include alternative keyboards, eye-tracking systems, voice control software, and switch devices.
Try completing this form with the motor control simulator enabled. Adjust the tremor intensity and response delay to experience different levels of motor impairment.
Motor Control Simulator
This simulator demonstrates the challenges faced by users with motor control difficulties. The tremor effect makes precise movements difficult, while the response delay The tremor effect makes precise movements difficult, while the response delay simulates slower reaction times that some users experience. Try using the interface with these challenges enabled.
