Lumina Go turns your iPhone into a full-featured wireless remote for BLE-enabled projectors. REMOTE CONTROL Use the intuitive D-Pad for directional navigation, OK, Back, Home and Menu. Adjust volume, focus, and switch input sources — all from your phone. TOUCHPAD / MOUSE A large touch area lets you move the on-screen cursor with one finger, tap to click, two-finger tap for right-click, and two-finger swipe to scroll. Adjustable cursor speed from 0.5x to 3.0x. KEYBOARD Full QWERTY keyboard with letters, symbols and special keys. Type directly on your projector without an external keyboard.
