Limiting area of tracking

[khenshu]

Hello,

I am currently working on small C# app where i track the fingers. While tracking in the middle of the pyramide is great, the more it gets to the edges, the worse it gets (which is understandable). I found the area where i can get good results. Now i would need to limit my app/leap with constraints, so the user wont be able to get results from the "poor tracking" part of the space.

I thought about limiting it trought x,y,z with if however, i am not sure if this would work, as the Leaps space is changing with distance from device. device.Vertical/Horizontal angles are not going to work, as they are read only.

Was anyone solving something like that and may guide/help me please?

Thanks.

The easiest way would be to use the interaction box and normalize the coordinates. The interaction box is a rectangular prism (i.e. box) guaranteed to be completely within the field of view. Normalizing the coordinates converts them to use this box's bottom, left, lower corner as the origin. Any coordinate in the range 0-1 is within the box. If you want to limit the interaction area even more, (although only the base of the box will be near the edge), you could reject any data outside the range .2 to .8 (for example).
