手勢飛行 Gesture Flight

▶ 開始飛行 Start

進入後按右上角「📷 手勢」並允許使用相機。滑鼠 / 觸控撥球也可以用。
Tap “📷 手勢” at the top right and allow camera access. Mouse / touch swiping works too.

怎麼操作 How to fly

• 用右手，手放在鏡頭正前方 = 手在球上；用指尖撥球：前後、左右飛。
  Use your right hand. Hand centered in front of the camera = hand on the ball; swipe with your fingertips to move.
• 手掌立起、面向螢幕扭轉 = 轉向（像轉方向盤）。
  Palm facing the screen, twist like a steering wheel = yaw.
• 握拳 = 停；手移出色塊 = 球靠慣性繼續轉。
  Fist = stop. Move your hand out of the zone = the ball keeps spinning.
• 手離鏡頭太遠（約 85 cm 以外）不會被採用，後方人群的手也不會干擾。
  Hands too far away (≈ 85 cm+) are ignored, so people behind you don’t interfere.

須知 Notes

• 影像只在你的瀏覽器裡辨識，不會上傳。Video is processed locally and never uploaded.
• 相機只能在 https 網頁使用；下載 HTML 直接開啟會被拒絕。The camera needs HTTPS; a downloaded file opened locally will be denied.
• 手機請橫放並固定；第一次載入模型需要網路（約 8 MB）。On a phone, use landscape on a stand. The first load downloads the model (~8 MB).
