Position Listener

2012-05-15T16:30:49Z

Hello,

How can I make an MTRectangle constantly listen for the position of another component, and change its own position according to possible changes in the position of the component? Is there a position listener?

Thanks

Hi all,

Cheers!

46” DSI COMPLETE system for sale

2012-04-12T18:37:52Z

My group and I designed and developed a 46” DSI table from scratch. We no longer need the table and would like to find a good home for it. It was just completed and has approximately 15hrs of run-time. So basically everything is BRAND new. The table is located in Orlando, FL, but we are willing to help move the box to at least a few bordering southern states. This is a perfect solution for someone looking for a high-end final product that doesn’t have the time/effort to do it themselves. THis is probably a much cheaper solution than buying these retail MT tables as well. There is probably a lot I’m leaving off, so if this looks interesting to you, please contact me for more information.
Price is $4,300 OBO. Depending on the state, this includes travel costs. Thanks!

One way mirror with a Kinect question…

2012-05-13T18:55:03Z

For some reason my brain isnt functioning… so I figured I would toss up a post and see if I could get any input on a project I am starting on.

I am looking to make a one way mirror… but with a techie twist.

Behind the mirror would be a Kinect and an HD camera, as well as an LCD display.
This mirror would be mounted in a bathroom on the wall as the primary mirror behind the sink.

Using the Kinect SDK, I am going to be programming some movement tracking and gestures for controlling a PC. THe LCD display will be used to display not only a metro style UI (when activated), but also the display from the HD webcam (which will be on a movement device for motion tracking). I want to be able to use the Kinect for the gesture tracking (spreading hands apart for zooming the camera display, etc) as well as speech recognition.

My brain fart however is the use of the Kinect behind the one way mirror. I want the outer surface to be reflective (as a typical mirror would be) but still allow the IR from the Kinect to penetrate through as much as possible. Any suggestions or ideas on accomplishing this?

My end goal is to use this as an ultra techie bathroom mirror for my wife and I. She can use it for her makeup and I can use it for shaving as well as prepping with news/radio/stock tickers etc in the mornings. Since we have double sinks… I may do two of them if they work out well enough. One for her and one for me! :D

CCV 1.5 & MultiProjectors / How to ? …

2012-05-15T19:14:57Z

How to setup CCV 1.5 with MultiProjectors ?

One of the best feature of CCV 1.5 is that it can handle various cameras.
This means that not only you can reduce drastically vision distance for single projector setup ;
but that also makes a powerful tool for very large multitouch displays using multiple projectors .
However, searching around in the forum i didn’t find any precise answers or tutorial that deal with this subject .
The goal of this topic is to discuss solutions, which will hopefully leads to a comprehensive tutorial for calibrating CCV on multi monitor setups .

To open the discussion , a couple of questions and a quick survey of related topics.

Is there a the way to specify to CCV settings the size of the calibration grid ?
(for example two VGA side by side will means : 2048 x 768 ... )

Is there a way to resize and move CCV 1.5 calibrating grid
as in previous versions of CCV I could enter calibration and by using arrow and a,w,d,s keys I could move and resize the calibration grid.
(.../viewthread/13911/)

What are the best practice on the calibration side of CCV

how to align multiprojectors ? What are the best practice for blending and stitching : softedge vs hardedge

Some members mention some solutions

AudioMind suggests this :

Use an AutoHotkey script:

#i::
SysGet, VirtualWidth, 78
SysGet, VirtualHeight, 79
WinMove, A, , 0, 0, % VirtualWidth %, % VirtualHeight %
; Remove the spaces before and after VirtualWidth/VirtualHeight

How does this work ? and what means : SysGet, VirtualWidth, 78 , SysGet, VirtualHeight, 79 ??

TouchMi also suggest a

Simple Multiple Projector Blending/Warping and CCV 4 Cam Tutorials with Immersive Display : (http://nuigroup.com/forums/viewthread/12598/)

This video is great but it doesn t clearly explain neither how you setup ccv .

More suggestions ? More solutions ? Feel free to contribute

First ever build: 32"-36” FTIR coffee table

2012-05-14T22:43:22Z

Hi, this if my first ever build and I’m hoping to keep a record/open discussion about it here. I will keep the first post updated as much as I can on recent progress.

What I’m aiming for is that the screen will be in the middle and have some space on the sides to rest cups or other objects. To deal with any spill that might happen, I have chosen to use a 225 Neutral Density Frost Lee Filter which is supposed to be waterproof, if I remember my reading right. The screen itself may be anywhere between 32” to 36” depending on what kind of size the image turns out to be after I get the projector set up. The main function of the table would be a sort of entertainment center. I plan to have speakers embedded into the frame and we would be able to play music through them. Using a program called TVersity(ver. 1.9.7, starting with ver. 2.0 they have begun charging for the software!) I will be able to stream movies to an Xbox 360 console to play on the television that is also in the living room. The table will be used for games and the like as well.

Much of this past the display has not been looked at in depth yet. Taking it one step at a time.

I am discussing my display options here.

Current ideas:

Input type- FTIR
Display type- Projector
Speakers- at least 2 for stereo sound, debating increasing the number
Diffuser material- 225 Neutral Density Frost Lee Filter
Compliant surface- silicon/xylol mixture applied using the Tinkerman method
Surface- 14mm thick Acrylic, surrounded by IR LEDs.
Planned dimensions- 30” x 48” x 20” this include the lips that are not the touch surface. The touch surface will be an area approximately 32” - 36” in the center
Camera- Modded PS3 Eye (might need a wide angle lens. Haven’t looked into it yet.)

I am open to any and all discussion with anything regarding the project. I am very new to all this and will take any input gladly. If you have any questions/criticism or suggestions for improvement, feel free to chip in.

Hot Mirror Did not Work !!!

2012-05-12T05:39:53Z

Hello,

I am building my first FTIR setup with tinkermans method for the complaint surface with customized Ps3 eye camera
the projector emits IR so i read a lot of articles most accurate solutions are
1) using Hot mirror mounted to reflect the IR from the projector

2) using two mirror setup to reflect the IR

i used the hot mirror method, since i want to do the easy part. However, i still have the Hot Spot from the projector..

Is there any solution other than changing the setup? my dead line is near and i don’t have time to change the setup !!:(

This is my setup attached

----------------------------------------------------------------------------------
The last attachment is the Hot mirror mounted on the projector lens
