Using Finger Touch Operations

You can use your finger to interact with the projected screen, just as you would use an interactive pen. You can use either a pen or your finger, or use both at the same time.

When performing touch operations with your finger, you can use two fingers in built-in annotation mode and up to six fingers in whiteboard mode.

Install the Touch Unit as described in the Touch Unit and Control Pad Installation Guide.
Turn on your projector. This automatically turns on the Touch Unit also. The blue light on the Touch Unit remains lit.

Note: If the blue light does not turn on, press the Menu button on the remote control and make sure the Extended > Easy Interactive Function > Touch Unit Setup > Power setting is set to On.
Calibrate the pens.
Adjust the angle of the Touch Unit as described in the Touch Unit and Control Pad Installation Guide.
Calibrate for finger touch interactivity.
To write or draw on the projection surface in built-in annotation mode or built-in whiteboard mode, do the following:
- To select a projected item, such as an icon, tap the projection surface with your finger.
- To draw on the projected screen, tap the projection surface with your finger and drag it as necessary.
To use your finger as a mouse in PC Interactive mode, do the following:
- To left-click, tap the board with your finger.
- To double-click, tap twice with your finger.
- To right-click, press the board with your finger for about 3 seconds.
- To click and drag, press on and drag an item with your finger.
- To scroll, drag your finger on the screen.
If your operating system supports these functions, you can also do the following:
- To zoom in or out, touch an item using two fingers and either move your fingers away from each other (zoom in) or toward each other (zoom out).
- To rotate an image, touch the image with your fingers and rotate your hand.
- To drag up or down on a page, or move backward or forward in a browser window, use swiping gestures or flicks.

Note: Finger touch operations may not work correctly with long or artificial nails, or fingers wearing bandages. If your fingers are too close together or crossed, or your sleeve or free hand touches the screen, finger touch may not be recognized. Some operating systems may not support gestures.
