TV Igo Board Extractor

igoboard

An app that analyzes a TV-broadcast Igo problem from a live camera shot or saved photo, then extracts only the board area for easier printing. It is designed with older Igo fans in mind.

  • Extracts the board from a photo of a TV screen
  • Can also analyze previously saved images
  • Prints only the board area, so manual cropping is not needed
  • The app detects the board as a yellow rectangular area, so it may also work with shogi boards.
  • Images of real brown Igo boards may not be detected correctly.
  • Recognition works best when the full board is visible and glare is reduced.

Ritual Spring / Balloon Burst

BalloonBurst

A turn-based chicken race game meant to be played by multiple people taking turns. It includes the iPhone game Ritual Spring and the Apple Watch game Balloon Burst, both built around a random threshold where crossing the limit means defeat.

  • Designed as a multiplayer turn-taking chicken race where players test who crosses the limit
  • In Ritual Spring, you trace around a spring with your finger to advance a ritual.
  • When the random threshold is exceeded, an evil spirit emerges and drags you in.
  • The current app structure bundles the watch app inside the iOS parent app.
  • The iPhone version uses touch input and vibration effects; the Watch version uses the Digital Crown and haptics.
  • Both games are based on the same “lose when you cross the limit” rule.
