Braille Making Assistant—CS-09

For (With Whom)

People with little finger-pressing force, or whose fingers become painful, when making braille.

Why

As part of the work at an employment support facility, there was a task of adding braille to business cards. We found that the handle of the commercially available braille-punching tool is small and puts a burden on the fingers and hands when the work is repeated, so we decided to make this self-help device.

How

We assessed the task of adding braille to business cards. With the small portable braille writer, the stylus slipped when punching braille, and too much force was sometimes used, making holes through the paper. We therefore first made a jig for the braille writer and adjusted the number and size of the holes needed. We also found that the handle of the braille-punching tool is small and puts a burden on the fingers and hands when the work is repeated, so we made this self-help device.

Outcome

Work efficiency in adding braille to business cards at the employment support facility improved. With the off-the-shelf handle, repeated work tended to make the fingers sore and the working posture tended to become strongly hunched forward, but after using the Braille Making Assistant, posture improved and the work could be done with less muscle tension throughout the body.
