Summary
This study introduces an eyeglass-based infrared (IR) computer interface to aid individuals with disabilities, such as spinal cord injuries, in operating computers. The system translates tongue movements into IR signals for seamless computer control.
Area of Science:
- Biomedical Engineering
- Assistive Technology
Background:
- Individuals with severe motor impairments, including spinal cord injuries, face significant challenges operating standard computer interfaces.
- Existing assistive technologies may not offer sufficient convenience or adaptability for all users.
Purpose of the Study:
- To develop and present an innovative eyeglass-type infrared (IR)-controlled computer interface.
- To enhance computer accessibility for disabled individuals with limited mobility.
Main Methods:
- The system comprises three components: an IR transmitting module, an IR receiving/signal-processing module, and a main controller (Intel-8951 microprocessor).
- Tongue-touch circuitry converts movements into IR and low-power laser beams.
- The receiving module processes IR signals into standard control pulses for computer input.
Main Results:
- The developed interface allows eyeglass-mounted modules to control computer keyboard and mouse functions.
- The system effectively translates processed IR signals into verified computer commands via a mapping table.
- The design facilitates convenient computer operation for users with restricted movements.
Conclusions:
- The eyeglass-based IR computer interface offers a viable solution for enhancing computer accessibility for the disabled.
- This technology has the potential to improve the quality of life and independence for individuals with spinal cord injuries and similar conditions.
- The modular design allows for flexible mounting on eyeglasses or artificial limbs.
