Inkbraille as a potential new reading system for the blind

Area of Science:

• Human-computer interaction
• Assistive technology
• Sensory substitution

Background:

• Embossed braille presents challenges, including bulk and cost.
• Inkbraille offers a reduced-size ink-image alternative to embossed braille.
• Existing assistive technologies can be leveraged to test novel reading systems.

Purpose of the Study:

• To evaluate the initial readability and learning potential of Inkbraille.
• To compare Inkbraille reading performance with conventional braille and typed letters.
• To assess the impact of a specific reading aid on Inkbraille comprehension.

Main Methods:

• Comparison of three tactile reading modes: embossed braille, Optacon-mediated typed letters, and Optacon-mediated Inkbraille.
• Assessment of initial reading performance and rate increases over limited exposure sessions.
• Utilizing the Optacon, an electronic reading aid with a vibrating pin display, for tactile output.

Main Results:

• All participants could read Inkbraille immediately upon introduction.
• Significant improvements in Inkbraille reading speed were observed after brief, repeated exposure.
• Inkbraille and letterprint reading rates were comparable when mediated by the Optacon.

Conclusions:

• Inkbraille is a viable tactile reading system with a low initial learning curve.
• The Optacon may impose a rate limitation, potentially masking Inkbraille's full reading speed potential.
• Further research with dedicated Inkbraille translation devices is warranted.
