Type Alias: KmtOutputEvent ​

KmtOutputEvent = { delta: Point; type: "pan"; } | { anchorPointInViewPort: Point; delta: number; type: "zoom"; } | { deltaRotation: number; type: "rotate"; } | { style: CursorStyle; type: "cursor"; } | { type: "none"; }

Defined in: packages/board/src/input-interpretation/input-state-machine/kmt-input-state-machine.ts:170

Output events produced by the KMT state machine for the orchestrator.

Remarks ​

These high-level gesture events are the result of recognizing patterns in raw DOM events. The orchestrator receives these events and coordinates camera control and observer notification.

Event Types:

  • pan: Camera translation with delta in viewport coordinates
  • zoom: Camera scale change with anchor point in viewport coordinates
  • rotate: Camera rotation change (currently unused in KMT)
  • cursor: Cursor style change request (handled by state uponEnter/beforeExit)
  • none: No action required

Coordinate Spaces:

  • Pan delta is in viewport pixels
  • Zoom anchor point is in viewport coordinates (origin at viewport center)
