Computation of Indian Abacus is possible while sitting on the floor

The photos given clearly shows that, doing computation by using Indian Abacus is possible while sitting on the floor which is never possible with any other abacus which is now in use, because while sitting on the floor children keeps shaking their legs position as they feel uncomfortable to sit in the same position for a long time. While working out on any other abacus when children try to change / shake their sitting position unknowingly as when they feel uncomfortable, the Abacus computations could get disturbed and the values will change, whereas the same never happens with the usage of Indian Abacus, because, Indian Abacus stable sliders will not move automatically and the colorful slider / images enable children to identify the value without any strain.
