How To Build a Multitouch Table - Part 1

[scamslat]

Why is it my table does not detect movement? :(

[PeauProductions]

@scamslat Please post on the NUI Group forum with specific build questions

[dogg06]

What kind of IR sensor you use ? Can you give me on exemple, a name, please? Thank you!

[PeauProductions]

@dogg06 The "IR sensor" in these setups are essentially the cameras tracking the IR light blobs.

how thick is the acrylic?

[PeauProductions]

@0X1D1Z3D There are many setups shown in this video, but the acrylic in most of them was about 6mm thick. The larger the setup the thicker you need to go.

im sorry but i never like to buy something online n i want it to know

where can i get them like what local store n how to make the power supply

[PeauProductions]

@TheMrRocksar What parts are you looking to buy?

[TheMrRocksar]

@PeauProductions i wanna buyu only the lasers n the power supply for them oh n some led lights

[PeauProductions]

@TheMrRocksar If you are in the Southern CA area then you can get the parts from our shop, otherwise you can buy them online from us.

[dogg06]

@PeauProductions I can use IR LED and IR Photodiode ?

[PeauProductions]

@dogg06 Yes you can but the software to determine where the object is between the diode and receiver would take awhile to figure out. We sell Infrared Touch Frames that are ready to use frames using this type of detection (no camera). See our online store for pricing and sizes.

hey im making this for my school progect n i will like to know how to get n where to get the lasers n led lights n how much r they thank u

[PeauProductions]

@TheMrRocksar Please see the peauproductions store for pricing on the components needed to make these setups

[kastaramation]

after all the materials are available how can u make the screen touch! connect the ps3 eye how can the screen be precise and which software is the best for making ur screen touch and is straight forward

[PeauProductions]

@kastaramation Once you have the camera attached, use a tracking program such as CCV (ccv.nuigroup.com)

[kastaramation]

@PeauProductions im still new in this exp. 2 once i have used the ccv program how can i use the ccv work in windows 7 ? suppose that i have restared my pc but the camera is still connected ! once the pc goes into the desktop automically it will be touch or i must re start the ccv program ?

[PeauProductions]

@kastaramation You must always have ccv up and running to have the camera tracking your fingers. You can have it start up automatically when you start your computer if you want.

[LmaoFIFA]

can you use this to web browse. e.g could i search youtube

[PeauProductions]

@LmaoFIFA Yes all you need is to use a TUIO mouse driver to emulate a mouse on a normal desktop

[oivrlol2]

[oivrlol2]

@PeauProductions thanks when i make this i ask you when i have questions

@PeauProductions ok thanks

whats is the thickness of the acrylic because I have heard that you cant use acrylic thinner then 8mm

[PeauProductions]

@KrunchieHD I don't know what method you are asking about, but any method that uses the LEDs along the edges should typically be at least 8-10mm thick. You want it large enough so that as much light from the LEDs goes into the sides of the acrylic.

[ONixaO]

Why I cant use plexyglass

[PeauProductions]

@ONixaO Yes you can use plexiglass as it's the same thing as acrylic.

[KrunchieHD]

can you use any projecter?

[PeauProductions]

@KrunchieHD Yes, but some models, such as the short throw projectors work better since they produce a larger image from less distance.

[KrunchieHD]

which one of the five methods do you recommend buliding?

[PeauProductions]

@KrunchieHD Choosing which method to build depends on a lot of factors such as size, lighting conditions, budget, planned usage, etc. You can send us an email to get some help if you'd like. Please use the contact form on our website.

[KrunchieHD]

Are the LED Lights IR Lights?

[PeauProductions]

@KrunchieHD Yes

[MyJesusfreak45]

is there an attachment i could buy or make to turn a normal projector into a short throw projector?

[PeauProductions]

@MyJesusfreak45 Not typically unless the manufacturer sells one. You can use a mirror to bend the projected image path to make a setup with a shorter height.

[WaYoH676]

uhh I searched wut a fiducial marker is... I dont understand, could you explain it to me, plz ??

[PeauProductions]

@WaYoH676 A fiducial marker is simply an object that has a pattern on the underside that is placed on the surface and the camera below sees. There are many examples of fiducial tables on the internet, for instance you can search for the ReacTable system to see a setup which the fiducial objects control music loops.

[Vorror44]

For the DSI version, you say that you can mount a LCD setup under the Endlighten Acrylic... how would that work and can you make a vid for that?

[PeauProductions]

@Vorror44 Just take the LCD apart and place the LCD matrix under the Endlighten. Please see the NUIGroup Forums for people who have built LCD DSI setups.
