Feel the Balance: An Interactive Web Game Concept for Communicating Seated Balance and Trunk Motor Control Research

Concept paper and interactive prototype, version 1.0 (November 6, 2026). Later versions may be released. This record contains two files: the concept paper and the playable browser prototype that goes with it. Feel the Balance is a concept for browser-based games for the Spine Neuromechanics Lab website at the University of Delaware. Visitors sit in a virtual version of the lab's seated balance chair and try to keep it steady as the tasks get harder. Three tasks follow published unstable-sitting tests: holding still with eyes open and closed, moving to targets, and sliding along lines. After each task, players see a simplified version of the measure researchers use and how their score compares with published values. The paper describes the concept, audiences and learning goals, the game modules, the simulation model, and its features and design principles. The prototype is a static web page in HTML, CSS and JavaScript with no external libraries. Its modules are Move to lean; a balance challenge with three tasks (hold still with eyes open and closed, hit the targets, stay on the line); and Inside the lab animated scenes. It is a demonstration for learning, not a clinical test, and it collects no data. Access: the files are restricted. Only this description is public.
