Kolam is a traditional and very popular graphical folk art practiced in the southern India. Without haptic sensation, however, the identification of Kolam is not possible by the blind or those with low vision. This paper describes a tactileline drawing tool, which makes the Kolam pattern accessible to the visually impaired and is available learning spatial pattern recognition while they are playing it. The tool was developed as a universally designed cube with 6 primitive patterns on each of 6 sides. These primitive patterns were found by researching how to draw Kolam and other similar traditional patterns of Celtic knot in Europe or Soma paintings in Africa. Kolam patterns In south Indian villages, the courtyard in front of each house is decorated every morning by drawing of traditional designs called Kolam.
