-What's a MTmini?-
-------------------------------------
A Multitouch Mini, MTmini for short, is a cheap, small, portable multitouch pad. It can be used for all different purposes including: drawing, OS navigation, multitouch operation, games, entertainment, experimentation, and more. I created the Multitouch Mini to show people how something that seems complicated or 'magical' can be made simply and at low cost.


-How's it Work?-
--------------------------------------
When you place your fingers on the surface, shadows are created where your fingers are placed. The webcam sees these shadows and sends the image to the tracking software which tracks the shadows as they move on the touch surface (paper).

All you need is a room with (at least) some light; a dark room will not work. Even room lighting gives the best results. Lights shinning from multiple directions onto the multitouch pad gives better results than lights from one direction.

I just want to know if it's the hight of the box should be respected and what is the good one ? thx

[cerupcat]

@AnnakiVEVO The height doesn't need to be the same as the video. The height just needs to be tall enough for the camera to see the surface. If the height is too short, the camera will only see a small space. The higher it is, the bigger your touch area can be.

@cerupcat your answer is clear and helpful, thank you !

[renji2l0s]

@TheMBenardJunior the box can be made of any opaque materials, translucent and transparent materials won't work well because light can pass through and can confuse the webcam.. you can change the size of the box and size of the plexiglass but the larger the glass the bigger space you will need to put you MTpad.
