後半に日本語の説明あります。
A tool that allows for visually impaired/disabled people to distinguish the difference in colors of the object they are touching through the difference in vibrations they feel in their fingertips

By making three vibrators vibrate in response to the three primary colors, it is possible to distinguish between difference in colors by feeling through the fingertips.
Through the motion of touching an object, you feel the difference in color through your fingertips, so it is possible to perceive the distribution of color.
People that are color blind can use the tool to confirm colors.
