Problem we are trying to solve?

Due to Covid 19, remote learning has been a constant and so have been online examinations.
But proctoring has always been a task and cheating and unfair practices have always been a problem.

Problems with the exisiting sytem?

The current solutions assumes to have 2 platforms

  • One for testing purposes like Google Form for writing exams
  • And another, video conferencing platforms like meet or zoom for manual proctoring.

Our PS poses to develop an application that can automatically proctor and monitor students, without the need of manual proctoring - ie without a teacher's aid.

Market & User Research

  • On market research, the products available found, are paid.
  • On user research and feedback from students, UX of such platforms isn't upto the mark.
  • UX from the client's end isn't frictionless, it was expected by the client to upload questions on their platforms.
  • The existing product doesn't seem to have an accessible Admin Dashboard.

That's where we come into picture.

Architecture and Design

The tradeoff in a Hackathon: Speed over quality

But something that we are proud of is, we tried to follow ideal software development practices.

Creating a Test and Dashbaord


Create Test Dashboard

Creating a test and expecting a Google/Microsoft Form Link

Admin Dashboard: Tests arranged chronologically.

Start Exam

  • After logging in and entering the unique test code.
  • Live Snapshots will be captured, periodically and will be analysed for the following :
    • Face Verification
    • Face Cover/Visibility
    • Multiple People Detection

Start Exam


Building a chrome extension for track of tabs


Checks for cheating

  • Face Verification
  • Voice Detection
  • Multiple People Detection
  • Dev Tools Check
  • Multiple Tabs Check
  • Full Screen Check

Full Screen Detect Dev Tools
Face Not Visible Multiple People

Also, ideas rejected: These were rejcted due to false positives and unsurity of cheating.

  • Eye Tracking
  • Object detection
  • Mouse Tracking


Test Admin Dashboard

  • The following warning logs, data and statistics will be emailed to the Admin after the test.

Test Dashboard Test Dashboard 2

Test Dashboard: Admin can see statistics - no. of students with warnings and above the threshold.

Admin Dashboard: Admin can Terminate or Continue a students exam based on warnings.

  • extension: Chrome/Edge extension to keep a track of browser tabs.
  • model: Model APIs for Machine Learning.
  • server: The backend for the application.

Client

For local setup of frontend:

  • cd client
  • npm i
  • npm start
  • Go to localhost:3000

Model

The complete setup can be found in the model directory.

NOTE:

  • Apart from this tensorflow and tensorflow_hub should be installed .
  • The face-pose-estimation model is not final it is just a placeholder for now(will improve it as we get time).
  • How to convert javascript array for image into image tensor that part is remaining.
