Cognitive Load Real-Time Monitoring Simulator

An interactive demo driven by real HPO-CLD Tobii eye-tracking data and LSTM V2.1 warning outputs. Instead of showing static model scores, it lets the audience see how the system detects rising cognitive load from eye-movement instability and turns that signal into human-centered support.

Scene 1: Eye-Movement Stability Contrast

Fused streams only (no normalization in the simulator): pupil = tracking-area x/y; gaze = unit direction x/y. Missing samples are exported as null and the trajectory breaks there.

Scene 2: LSTM Real-Time Warning

Adjust the indicator and threshold, then watch how the warning probability (red) co-moves with normalized instability signals (overlays).

Scene 3: Augmented Intelligence Intervention

The warning does not make decisions for the user. It makes an invisible cognitive state actionable. The audience chooses an intervention and sees how the system can reduce load while keeping the human in control.

Waiting for an intervention choice. This scene connects model output to the core idea of Augmented Intelligence: the system provides evidence, and the human makes the final decision.
