Which is a method to accommodate motor control problems?

• A. Eye/head tracking devices
• B. Keyboard and mouse are required
• C. Manual operation only
• D. Standard joysticks alone

Answer: (A)

When addressing motor control impairments, alternative input methods that don’t rely on fine hand movements are essential. Eye-tracking and head-tracking devices let a user control a computer by where they look or by how they move their head. The system translates gaze direction or head orientation into cursor movement and selections, often using dwell-time (holding the gaze on a target) or switches to confirm choices. This reduces the need for precise hand or finger control, enabling typing, clicking, and navigating software even when hand function is limited. That’s why this method fits best: it directly bypasses the challenge of manipulating a keyboard or mouse, which require reliable hand/arm control. In contrast, a keyboard and mouse, manual operation only, or standard joysticks all presuppose usable hand or arm movement, making them less accessible for motor control problems.
