strokeurlg

Strokeurlg is a fictional or hypothetical standard for encoding sequences of handwritten pen strokes into a compact, shareable URL-like string. The name combines stroke, URL, and generator to indicate its function: translating gesture data into a web-addressable representation.

Overview: Strokeurlg is designed for applications that capture freehand input from digital pens, tablets, or touchscreens and convert the resulting stroke data into a concise, URL-safe token. The token is intended to preserve essential geometric and temporal features of a drawing or handwriting while minimizing data size, allowing quick sharing and retrieval.

How it works: The core workflow begins with stroke capture, collecting coordinates, timing, and pen-down/pen-up events. The data is normalized to a common coordinate system and down-sampled to reduce detail while retaining shape. An encoding stage translates the sequence into a text string using a compact, URL-safe alphabet and optional compression. The final string is appended to a base URL as a parameter, often with versioning and metadata flags (e.g., color, stroke count). A rendering service decodes the token, reconstructs the strokes, and displays the result.

Usage: It is used in educational tools, collaborative drawing platforms, and accessibility services to share handwriting or sketches without sending raw image data. It enables quick previews and offline storage of gesture-based content.

Limitations: Privacy concerns arise since stroke data can reveal content; accuracy depends on input quality; extremely complex drawings may exceed token limits; not yet universally standardized.
