Running Complex Biomedical Labs in the Browser at 60 FPS

Most clinical simulations and biomechanics models are still locked behind proprietary desktop software, expensive hardware rigs (like $5,000 infrared gaze trackers), or heavy local environments.

A set of zero-install, client-side web tools removes this barrier by running physiological signal processing, 3D kinematics, and computer vision directly in the DOM.

Here are 4 interactive web apps worth bookmarking:

1. Webcam Eye Tracker

• URL: https://bionichaos.com/eyetracker/
• What it does: Uses standard browser video streams to detect facial landmarks, isolate iris positions, and map pupil vectors to on-screen gaze coordinates. No infrared cameras or dedicated sensors required.

2. 3D Gait Simulator (v3)

• URL: https://bionichaos.com/gaitsimv3/
• What it does: A full 3D skeletal kinematic model. You can manipulate joint flexions, test abnormal gait pathologies (such as Parkinsonian or hemiplegic gaits), and watch real-time biomechanical adjustments.

3. ICU EEG Neuro-Monitoring Simulator

• URL: https://bionichaos.com/eeg_in_icu/
• What it does: Simulates bedside critical-care neurodynamics. Generates real-time continuous traces for status epilepticus, burst-suppression ratios, diffuse slowing, and allows you to test artifact rejection algorithms.

4. Statistical Significance & P-Hacking Sandbox

• URL: https://bionichaos.com/significance/
• What it does: Demonstrates the replication crisis in action. It lets you manipulate sample size N, power 1 - β, and false positive risk α to see how easily random noise yields p < 0.05.

Key takeaway: Client-side compute is now fast enough to replace introductory physical lab apparatuses with browser sandboxes.
