Virtual Soroban Engine

Ditch the Webcam Frame.
Teach on a Digital Abacus.

A digital abacus tool built into Kids, Teacher, and Admin panels. Students slide the beads of an interactive virtual Soroban directly on a computer, tablet or phone to compute sums—building real visual muscle memory without blurry webcams or arm fatigue.

Kids & Student Panel

Turns abstract worksheets into visual muscle memory.

Direct Bead Solving Calculate answers and test hypotheses directly on interactive beads.
Kid-Friendly Touch Physics Generous touch and swipe targets tuned for small fingers on iPads and phones.
Instant Formula Feedback Real-time bead validation that flags mistakes without waiting for teacher grading.
Zero Forgotten Frames Practice homework anytime from a browser—no missing wooden abacus excuses.
02 / TEACH Trainer

Teacher & Trainer Panel

Zero webcam glare. Zero arm fatigue from holding frames.

Screen-Share Ready Ultra-sharp contrast rods visible clearly even over low-bandwidth Zoom calls.
Teacher Rod Highlighter Glow target rods to isolate Units, Tens, Big Friends, or Decimal points.

The Old Webcam Struggle

Why Physical Wooden Frames Fail Online.

When tutors teach abacus online, holding up a bulky 13-rod master abacus to a tiny webcam is exhausting and ineffective.

The Webcam Barrier

Glare, blurry beads, and zero student interaction.

Your hand blocks the beads, webcam compression blurs the reckoning beam, and young kids easily get distracted or lose count. When students are only asked to type numbers on a keyboard, they fail to develop the visual image of beads in their mind.

  • Blurry camera view and hand obstructions during online classes
  • Arm fatigue from holding physical demonstration frames for hours
  • Students type answers into text boxes instead of training on beads
  • Practice stops whenever a child leaves their physical abacus behind
The ERPLI Solution

Interactive Sum Solving on True Soroban Beads.

ERPLI transforms the abacus into a living, responsive software instrument. Teachers demonstrate formulas in high-definition 60 FPS, while students manipulate the exact same digital tool on their end.

  • High-definition Soroban representation for clear screen sharing
  • In-abacus sum solving builds real visual muscle memory
  • Works seamlessly on phones, iPads, laptops, and smartboards
  • Auto-evaluates bead configurations with instant score feedback

Live Abacus

Move One Bead. Every Student Sees It Live.

Open a live abacus for a class or batch and demonstrate formulas in real time. Every bead you move is mirrored on your students’ screens, so the whole room follows the exact same Soroban state.

  • Broadcast to one student or a complete batch.
  • Keep everyone on the same rod and formula step.
  • Teach through live classes, smartboards, or revision drills.

Engineered For Mentors

Purpose-Built Features for Abacus Academies

Every single parameter has been tuned to preserve authentic Soroban rules while taking full advantage of modern web technology.

In-Abacus Homework & Exams

Assign daily homework where kids cannot guess multiple-choice answers. They must arrange the beads to the exact answer state, validating true comprehension of formulas.

Configurable Rods (5 to 17)

Start beginners on 5 rods (Units, Tens, Hundreds, Thousands). Expand to 7, 9, 13, or 17 rods as students advance to long multiplication, decimals, and square roots.

Real-Time Value Calculation

Instant tabular readout updates as beads touch the reckoning beam. Can be toggled on for teaching or turned off for testing independent student mastery.

Zero-Install Web App

Runs smoothly inside any modern mobile browser with zero app installation required. Works seamlessly on iOS Safari, Android Chrome, Mac, and Windows.

Custom Academy Branding

Align bead gradients, wood finishes, and reckoning beam dots with your academy's brand colors. Deliver an elite branded experience that impresses parents.

Bead Speed Analytics

Measure how many seconds a student spends per rod move. Spot students who struggle with Big Friend 10s complement transitions before exams approach.

Got Questions?

Frequently Asked Questions

How do students solve sums directly on the abacus?
Instead of simply typing numbers into a box, problems show on screen and students tap/drag the virtual beads. The system reads the mathematical state from the reckoning beam and automatically checks both intermediate step formulas and final answers.
Can teachers and students use the digital abacus at the same time in live classes?
Yes. ERPLI supports real-time synchronization. A trainer can present their master board to the whole batch, or drop into any individual student's abacus to inspect bead placement live and demonstrate a correction.
Can I customize the number of rods and bead colors for my academy?
Absolutely. From the Admin Panel, you can restrict rods per level (e.g., Level 1 has 5 rods, Level 4 has 9 rods), specify bi-color or uni-color beads, and upload your academy logo directly on the Soroban frame.
Does it support both touchscreen taps and mouse clicks?
Yes. The engine is tuned for multi-touch on iPad, Android tablets, and phones, as well as fluid clicking on trackpads and mice.
