Self Mode :  This mode is designed to enhance speed and accuracy in abacus operation. It follows the initial understanding of all single-digit numbers (0-9) and involves regular practice with these digits. The aim is to convert conceptual understanding into muscle memory (kinesthetic learning) by working with larger numbers and numerous rows of calculations.

• Auditory and Visual Number Presentation: Numbers are called out while being displayed to focus the user's attention. This concurrent presentation helps users input numbers into EYNKO with greater speed and accuracy.

• Immediate In-Line Correction: The system evaluates each number immediately after it is entered. This prevents continuous feeding of incorrect numbers and quickly highlights which numbers the user is struggling with. This saves time by eliminating the need to redo an entire sum just to correct one input.

Unwanted Moves Indicator: EYNKO is designed to encourage efficient input with fewer moves on the abacus. The system monitors the user's input and, if a number is achieved following an extra, unnecessary move, the number is highlighted with a black background. This visual cue helps users understand when they have made an extra move.
