Wii Balance Board Center of Pressure

This is an experimental project to get center of pressure (CoP) data from the Wii Balance Board (WBB) in the browser.

Demo available: https://measure-balance.netlify.app

Introduction

The goal of this project was to get the WBB to work on the Web. This is done by leveraging the power of WebHID.

There are numerous research studies done on the WBB and its potential clinical applications. However there has been little to no access for clinicians and patients to software that would enable them to use it.

This project will explore the possbile applications and share them on the web.

Features

Connect WBB to the browser
Calculate CoP while on the board
Display CoP in real time for biofeedback
Clear data plot, pause and play live feed
Record trials of balance using a timer or manually stopping the recording
Filter the raw CoP data using SwARII method developed by
Download raw and filtered data during trials as a CSV file
- CSV file will be formated in three columns: time(s), xCoordinate(mm), yCoordinate(mm)
Toggle LED on board

How It's Made

Tech used: HTML JavaScript Tailwind WebHID-API

Optimizations

add more metrics for measuring balance based on current research
change plotting interface to something more interactive and can show multiple plots such as d3
add backend so users can store data and compare it over time
improve UI to show interpretations of balance score
