Tips and Troubleshooting
Whenever using now!Board™, remember:
1. Set up your computer and projector first so the projected image displays clearly and uniformly.
2. After you have your computer screen clearly projected, then connect now!Board.
3. Have a clean line of sight between the now!Board camera and stylus or wand at all times.
4. Launch the software and follow the calibration instructions on the projected image.

Why does the calibration screen keep telling me to move the position of the laser?

Remember that the laser provides a general guide to help position the camera.

It is common for the laser to be positioned outside the absolute center of the screen and even outside the blue (+) center crosshair.

Use the larger RED circle as a rough guide. For example, if the calibration screen indicates to MOVE THE LASER UP, try repositioning the laser much higher on the projection surface, even if it is closer to being outside the red circle. Again, it is okay if the laser is outside the blue (+) center crosshair to calibrate.

Make sure the camera is 8–12 inches behind a tabletop or cart projector so that the projector's bright light is not causing interference with the camera's sensor.

Watch that laptops or other objects are not blocking the camera's full view of the projection screen. Try propping the camera up higher on a flat surface if there is a chance anything is partially blocking the line of sight between the camera and the stylus or wand.

Watch that you are holding the stylus correctly when calibrating. Blocking the sensor or tilting the stylus fin may cause the camera to misread the calibration points.

Do not hold the side button on the stylus when trying to calibrate or write.

Allow a second or two for the camera to see and react when you touch the calibration points with the stylus or when you press and release the button on the wand. Lifting away too quickly when calibrating can cause the camera to try to track a moving light in the stylus or wand.

Make sure the stylus or wand remains still and on target until the calibration screen prompts you to advance to the next calibration point.



Why does the calibration screen keep telling me to reposition the camera?

This likely indicates now!Board is either too close or too far from the projected image.

The now!Board camera has a range of 5–14 feet in order to accurately calibrate and track the stylus or wand.

Keep this simple equation in mind when setting up now!Board:

D = H + W

H is the height of the projected image

W is the width of the projected image

D is the resulting distance to place the camera away from the projected image

Example:

image Height (H) 4 feet + image Width (W) 6 feet = place the camera 10 feet away in total Distance (D) from the image

This equation holds true whether using now!Board with a portable, ceiling-mounted, or short-throw projector. It also applies to using now!Board with a flat-panel TV/monitor.

It is okay to approximate and place the camera slightly farther back than the required distance, but do not place the camera closer than the required distance.

Example:

If the required distance is approximately 8 feet, it is okay to place the camera at 9 feet, but not at 7 feet.



Why does the digital ink sometimes shoot or streak across the screen when writing?

This is a symptom of the camera losing sight of the stylus or wand temporarily and then relocating it.

It is likely caused by tilting or lifting the stylus or wand inadvertently so that its light is momentarily unseen by the camera.

Make sure you always maintain a direct line of sight between the now!Board stylus or wand and the now!Board camera. Watch that your body and/or objects in the room do no block either the stylus lens or the camera. Watch that your fingers don't fold over the clear lens on the stylus. Make sure you are not inadvertently pressing or holding the side button while trying to write using the stylus.

Many new users inadvertently tip or tilt the stylus, causing either the lens to not point directly at the camera, or causing the white tip of the stylus to disengage or not depress fully on the board. This improves quickly with experience.



How can I open files on my computer using the stylus or the wand?

Try double-clicking by tapping the stylus tip on the file or folder you wish to open twice in succession. Check your computer controls to slow the sensitivity of your mouse-clicks. This means you want the computer to allow longer time between each mouse click to trigger a "double-click" on your computer system.

You can also use the right-click button* on the stylus to open files via menu selection:

1. Position the stylus tip (but do not depress) over the object the user wants to right-click.

2. Press and hold the side button.

After the pop-up menu appears, release the side button and select from the menu normally by selecting only with the tip of the stylus (let go of the side button!).

*This is the same as Control + click on Mac.

Using the presentation wand, you may find it easiest to open files and folders using the computer mouse first and minimizing them to the task bar (Windows) or dock (Mac) during interaction. The presentation wand has no right-click capability.



How do I get the mouse cursor to align better with where I click with the stylus or wand?

For more accurate calibration, try touching each of the 9 blue calibration points in the exact middles of the crosshairs (+). Remain still with the stylus or the wand until the system tells you to advance to the next calibration point.

Be sure to calibrate using the wand if you know you are going to primarily be using the wand during interactivity. Calibrating with the stylus and then using the wand can cause the cursor to align a little differently to each device.

The calibration sequence can always be launched via Settings > Calibrate. Use your computer mouse to launch calibration if you are unable to control the cursor accurately relative to the displayed image.
