Drawing Dataset

The dataset consists of 1,498 tracings and freehand drawings by 110 participants for 100 image prompts. Our drawings are registered to the prompts and include vector-based timestamped strokes collected via stylus input.

Please right click the links below and "Save link as..." if it doesn't download automatically.

Image prompts.

All rendered tracings and freehand drawings in SVG and PNG.

Raw JSON data: tracings, freehand drawings, registered freehand drawings.

JSON data format:

{
  // each prompt
  "image": {
    // each drawing
    "participant": [
      // each stroke
      {
        "path": string (Unix timestamp, x, y coordinates at each vertex separated by comma)
        "pressure": string (pressure value at each vertex separated by comma)
        "color": string (hex code, e.g., "#000000")
        "width": integer (stroke width on a 800x800 canvas)
        "opacity": float (alpha value from 0 to 1)
      }
      ...
    ]
