(FAB) of Indian Abacus

1    The  Features, Advantages and Benefits (FAB) of Indian Abacus :

Feature1  Indian Abacus, as it looks with all the sliders in value position.

(sliders are like the beads in the convention abacus) The basic frame made of Quality polystyrene, which is a single integral piece, is chosen to be made in the “Yellowish Cream” colour, which is a very friendly background for the eyes to work with.  The basic frame consists of the upper and lower window positions, which are separated by a slim rib (which can be also called the bar), hosting the home points, represented by a thick “DOTS”.  The sliders could be moved up and down to display value & non value positions by uncovering and/or covering the colour images.

Advantage:Colour display makes the eyes catch the slider positions thereby the values distinctly.  The eye capture of the colours to determine the value many times faster than that happening in the conventional abacus where the beads are homogenous / uniform in colour and therefore distinction between the value and non value beads is very difficult.  Further the non value beads tend to disturb the vision and the abacus practitioner has a blurred vision of the value beads and the values.

Benefits:  Colour display of the slider positions and values strike the brain’s attentionmuch faster and clearer (many times more than the conventional abacus bead positions and values)
