Technical Requirements for E-assessment
What you need for smooth and reliable results
Lexplore’s E-assessment runs directly in the browser using webcam-based eye-tracking. To work well and give reliable results, make sure the setup meets these conditions:
-
Screen: A laptop or desktop with a screen at least 13" and resolution of 1024 px or higher
-
Webcam: HD webcam (720p), preferably 30 frames per second (slightly lower can still work)
-
Processor (CPU): Intel Core i5 / AMD Ryzen 5 or better
-
Browser: Latest version of Google Chrome, Microsoft Edge, or Safari (Mac only)
-
Power: Keep the laptop plugged in (avoid battery saver mode)
-
Internet: A stable connection - wired is best, otherwise strong Wi-Fi close to the router
-
Lighting: The student’s face must be clearly visible in a well-lit room. Avoid strong light from behind (for example, sitting in front of a window), as this makes the face too dark for the camera. Light from the front or side works best.
