This study developed a head-controlled pointing device for quadriplegic users, demonstrating it effectively emulates mouse functions. The device proved easy to learn and use, offering a viable computer access solution.
Area of Science:
- Rehabilitation Engineering
- Assistive Technology
- Human-Computer Interaction
Background:
- Quadriplegic individuals often face challenges with conventional computer input devices.
- Developing effective assistive technology is crucial for enhancing computer accessibility.
Purpose of the Study:
- To create a head-controlled pointing device mimicking conventional mouse functions.
- To assess the performance and usability of this device for quadriplegic users.
Main Methods:
- A head-mounted target and camera system were used with specialized software.
- Image processing tracked target displacement to control the computer cursor.
- Functional evaluations involved 24 multidirectional tests across two difficulty levels.
Main Results:
- No statistically significant differences were found in mean throughput or movement time across test repetitions.
- Performance remained consistent regardless of test difficulty level.
Conclusions:
- The head-controlled pointing device effectively emulates computer cursor movement.
- The device is user-friendly and quickly learned by quadriplegic individuals.
