Leap handsLeap 雙手

A Leap Motion as an instrument; the mouse is a simulated hand when you have none.把 Leap Motion 當樂器，經本機橋接；沒開橋接時用滑鼠模擬手。

Try these three things試試這三件事

  1. No sensor? The page falls back to the simulator after two seconds (or press “simulate” in the L1 panel): the mouse is your right palm, its height sets energy and its position sets hue.
  2. Press the mouse button to pinch: a ring of ink starts at the index fingertip.
  3. Hold Shift for the left hand and right-click for a fist: the ink falls.
  1. 沒有感測器？頁面會在兩秒後改用模擬（或在 L1 面板按 simulate）：滑鼠就是你的右手掌，高度決定 energy，左右位置決定 hue。
  2. 按住滑鼠鍵就是捏合：食指指尖會畫出一圈墨。
  3. 按住 Shift 是左手，按右鍵是握拳：墨會落下。

Needs: Leap Motion.需要：Leap Motion。 No hardware? Use Mouse as a hand.沒有硬體？用用滑鼠當手。

Read these lines讀這幾行

  • main.js:49–51 Drawing the hand is the one place a world reads the input directly.畫出手，是世界唯一直接讀輸入的地方。
  • main.js:92–110 The gestures reach the world through params: the timeline or a MIDI knob can play them too.手勢經由參數送進世界：時間軸或 MIDI 旋鈕也能彈它們。
