Published sheet, version 4

The heart

A labeled cross-section of the human heart. Muse Spark planned the parts, SAM 3.1 outlined them, and the teacher accepted Spark’s merge for the aortic arch, checked 11 parts and described two of them. The septum was left unchecked, so it is not touchable.

The tactile sheet for labeled cross-section of the human heart, as printed: the raised outlines with textures, braille labels, four corner marks lettered A to D, and a 100 mm bar.
The sheet as it prints, from tactile.svg, with the outlines from regions.json over it. Both are in page millimeters.

  • Move the pointer onto a part: a tone, then its name when you rest. Crossing a valve line says the line, then the part.
  • Click or tap a part to hear its name at once. Rest inside the outline, on no part, to hear the subject.
  • Keyboard: Tab to a part on the sheet or in the list, and press Enter. Escape stops speech.
  • The browser speaks only after a first click, tap or key press on the page.

This is a stand-in on a screen. The real product follows a fingertip on the printed, raised sheet with a phone camera, and plays the same tones and names. Questions need the live app and are not on this site.

The parts

From this sheet’s regions.json. Each button says the part’s name.

Touchable parts (11)

  • texture: grid.
  • texture: grid.
  • texture: dots.
  • texture: solid. Teacher’s note: “The right atrium collects blood coming back from the body.”
  • texture: lines.
  • texture: grid.
  • texture: dots.
  • texture: grid.
  • a point symbol (too small for a texture).
  • texture: dots.
  • texture: cross. Teacher’s note: “The left ventricle pumps blood out to the whole body through the aortic arch.”

Lines (4)

  • Tricuspid valve, a line between the right atrium and the right ventricle, not raised; a finger crossing from one to the other hears its name.
  • Chordae tendineae, a line in the right ventricle, not raised, listed in the key.
  • Semilunar valves, a line between the left ventricle and the aortic arch, not raised; a finger crossing from one to the other hears its name.
  • Mitral valve, a line between the left atrium and the left ventricle, not raised; a finger crossing from one to the other hears its name.

Not touchable (1)

  • Septum: not checked by the teacher, so not touchable. The pipeline’s note: holds points of right ventricle after a retry.

Outline

Resting inside the heart’s outline, on no part, says “Heart”.
