The Selection of the Appropriate Computer Interface Device for Patients With High Cervical Cord Injury

This paper explores suitable computer interfaces for patients with high cervical cord injuries, who have limited hand movement. Traditional computer input methods are not viable for these individuals. The study presents three cases where specialized input devices were used, including head-movement tracking, lip movement control, and forearm pronation. The goal is to help patients with high cervical cord injury select the most appropriate interface based on their remaining physical functions, thereby improving their ability to use computers for work, communication, and rehabilitation.

• 1
  Camera Mouse combined with a modified Micro Light Switch is suitable for patients with some forearm movement, enabling them to control a computer with reasonable typing speed and accuracy.
• 2
  SmartNav 4AT, which responds to head movements, provides stable clicking and dragging performance for quadriplegics with motor level C4.
• 3
  IntegraMouse, controlled by lip movements, is an appropriate interface for patients with weak breaths and difficulty controlling head movements, allowing them to perform online activities.
