Size |
| Indian Abacus : |
Almost same as the Conventional Abacus and hence no discomfort could be noticed. Advantages overweigh. |
| Conventional (Current) Abacus |
Same as before. |
Colour of Frame |
| Indian Abacus : |
Light cream colour acts as the best background for the colour images of the value positions - Green and Red. Light cream colour is very friendly to the eyes. |
| Conventional (Current) Abacus |
The colour of the Frame and the beads are darkish and contrast back ground needs improvement to give better visualization of objects. |
Slots / Rods |
| Indian Abacus : |
The slots in which the sliders move are having an ideal fit and the slider movement is very smooth and continuous. |
| Conventional (Current) Abacus |
The rods and beads have play due to imperfect fit. The movement therefore is not comfortable. |
Sliders/Beads |
| Indian Abacus : |
Sliders are chosen to hide and unhide the value positions, displayed through the colour images.
Visualization / Photographic memory possible at its best.
The images are of bright and contrast colours. There is absolute clarity and the stress level is nil.
The value positions and non-value positions are clearly defined through colour / no colour images. Hence the accuracy at the maximum speed of calculation is possible.
|
| Conventional (Current) Abacus |
Beads and background are of constant colours and there is no differentiation, which is the biggest weak point in this version of abacus. Photographic / visualization not so strong and much stress to eyes felt by children.
The value positions and non-value positions are not clearly defined and hence the accuracy suffers at high speeds. Stress results due to the deficiency.
|
Ease of operation |
| Indian Abacus : |
Same or better comfort in operation shall be experienced |
| Conventional (Current) Abacus |
Comfort as experienced now. |
Fixing the image |
| Indian Abacus : |
The sliders stay put in the positions when the Indian Abacus is vertically viewed while working and values don't get distorted. |
| Conventional (Current) Abacus |
The beads fall down and the values change while viewing the Abacus with value in a vertical position. |
