Accessibility
Built for more ways to learn
Navigation and forms support keyboards, visible focus, text labels and native dialog focus management. Icons are vector graphics, not emojis. Monitor channels use labels as well as color. Pause and Freeze controls let you stop moving traces; reduced-motion preferences stop simulator autoplay on first load.
Known limits
Visual ECG recognition inherently uses spatial waveform information. Canvas traces have accessible names, and the library supplies text descriptions. This is not a fully equivalent nonvisual rhythm-identification experience. Screen-reader and physical-device reviews remain outstanding; no WCAG conformance certification is claimed.
Using a keyboard
Tab moves between controls; Enter or Space activates buttons; arrow keys adjust sliders; Escape closes dialogs. A Skip to content link bypasses navigation. Manual strip calipers use labeled numeric inputs.
