Use of personal computing technology by deaf-blind individuals.

Area of Science:

• Assistive Technology
• Human-Computer Interaction
• Disability Studies

Background:

• Deaf-blind individuals face significant barriers in accessing digital information and communication technologies.
• Traditional interfaces rely heavily on visual and auditory cues, excluding those with combined sensory impairments.
• Existing assistive technologies may be costly or lack adaptability to individual needs.

Purpose of the Study:

• To develop and evaluate a novel system enabling deaf-blind individuals to effectively use microcomputers.
• To explore the use of International Morse Code delivered via vibrotactile feedback for computer interaction.
• To assess the potential for improved communication and vocational integration for deaf-blind users.

Main Methods:

• Implementation of a vibrotactile feedback system integrated with standard personal computers.
• Utilizing International Morse Code as the primary communication protocol between the user and the computer.
• Enabling deaf-blind users to receive screen information and provide input through tactile sensations.

Main Results:

• The system allows deaf-blind users to perceive computer screen content and receive typing feedback through touch.
• Users can operate keyboards and navigate computer interfaces similarly to sighted individuals.
• The vibrotactile Morse code system is adaptable to individual tactile sensitivities and has negligible hardware costs.

Conclusions:

• This vibrotactile Morse code system offers a technologically simple and cost-effective solution for microcomputer access for deaf-blind individuals.
• The technology significantly enhances communication capabilities, allowing interaction with sighted individuals through a shared medium.
• The system holds substantial potential to improve the quality of life and expand vocational opportunities for the deaf-blind community.
