To setup the Leap Motion controller for painting

Setting up the Leap Motion controller

Before you being painting, you need to make sure that the Leap Motion controller has an unobstructed view of your air gestures. It’s also important to get familiar with how Leap Motion and Corel Painter Freestyle capture air gestures.

There is a cone-shaped area situated above the Leap Motion controller that is called the field of view that allows the Leap Motion controller to detect and capture air gestures. Within the field of view, there is an additional box-shaped area called the painting space. The painting space corresponds to the Corel Painter Freestyle page and the air gestures that you make within the painting space are then translated into brushstrokes on the page. If the controller is not setup properly, it will have difficulty seeing and successfully capturing the air gestures in Corel Painter Freestyle.

The following diagram illustrates an ideal setup: 1) keyboard, 2) Leap Motion controller, 3) monitor, 4) field of view, 5) painting space, 6) distance above controller, 7) distance from controller, and 8) hover zone.

Tips for working with Leap Motion

To ensure Leap Motion’s ability to successfully capture all air gestures, follow these tips:

•

Make sure the lighting in the room is not too bright or too dim. For example, the Leap Motion controller may be unable to detect air gestures if you are in direct sunlight.

•

Remove any watches or jewelry, such as bracelets. These objects may cause reflections that interfere with the Leap Motion controller.

•

Wear a shirt that has form-fitting sleeves. For example, the movement of a flowing sleeve may be captured as an unintended air gesture.

•

Limit your movements to the painting space. Any movements that you make outside of the painting space will go undetected by the controller.

•

Make sure any object that you are using as a virtual brush is not shiny or reflective. For example, if you’re using a shiny pen, it may cause reflections that interfere with the Leap Motion controller. Try using a wooden chopstick or wooden spoon instead.

To setup the Leap Motion controller for painting

1

Install the Leap Motion controller according to the manufacturer’s instructions.

2

Place the Leap Motion controller facing up on a flat surface, such as a desk or table, approximately eight inches from and below your monitor.

If you’re using a laptop, the same eight inch distance applies. Therefore, you may need to elevate the laptop so that the Leap Motion controller is positioned eight inches below it. You may also want to choose a smaller-sized painting space to better match the laptop screen size. For more information, see To quickly resize the painting space.
