Trail Drawing Update
Yesterday we had abit of a breakthrough. Thanks to the help of a certain Mr. Topfner we have colour tracking working with the trail drawing patch, and collision dection works too. However there are a few kinks to sort out. For some reasons we need two LEDs of the same colour being tracked to get a trail drawn. And the trail drawn is a little patchy at times, so we'll need to either darken the room so the LEDs show up brighter, get more LEDs on the cars or track a colour on the car its self. Alot of stuff to get sorted in 3 days but we're getting closer.

MAX MSP Tracking....
The MAX MSP tracking is now working due to a little help from out resident genius... ;-)
This first picture shows the code as a whole, it demonstrates how many different windows are required to get this working and shows some of the logic between how our ideas are working...
Here shows a more detailed view of the piece of code that controls each car, the three boxes that run across the top keep the positions of each car and then as this moves down into the larger box it shows whether the cars have collided and then there is an opportunity to put an "if" statement were they to collide. There is also the positions of the trails for each car within this piece of code.
This final picture just shows the tracking working in practice, two red leds are being used and the code creates a box relative to the positions of the LED's and the area between them, if there were two red LED's and two green you would have two of these boxes, one for each colour.

Arduino Problems....
Spent today trying to discover exactly how to get the arduino boards to act as switches do disable power when a user crashes, i have been searching through the arduino website forums for things that are relative, but everything i find keeps not quite being enough.... I am currently waiting to be approved as a member of the forum so that i can post up our problem and hope to find some help.
On the bright side whilst trying to find answers to our problems i have stumbled across a reference page full of "if" statements and others which i should be able to apply so that when "car x" collides with "car y" something should happen!

Things to do in Max
Colour Tracking : Each R/C car will have a different coloured LED attached to the top, which a camera will track. 4 jitter matrixices in max will then track each car.
Project Trails: Using the co-ordinates gathered from the colour tracking, Max/Flash or Java will draw a a trail behind the car.
Collision Detection of trails: Comparing the co-ordinates of each car with the other cars, Max will work out weather a car travels over another cars trail.
Sounds FXs: Intergrate sound with collision detection. When a car is knocked out, a fitting sound plays.
Bluetooth Arduino Board
Intergrate with cars: Connect Bluetooth Arduino boards with cars to power on and off LEDs with the cars current status in the game. The boards will also cut the power to the cars when they hit another cars trail. Each board will be powered by 2 AA batteries.
Jobs over the weekend:
Fraser = Research Colour Tracking/ Collision/ Trail
Aaron = Research Trail/ Collision Detection in Max
Abdul = Research Trail/ Collision Detection
Roberto = Research Arduino Board Connectivity/ Car + LED connections

App Loader (+ User Background Image) Plus Guide!
AppLoader (+ user background image) is now available. I have modified the code slightly to allow for a background image of your choice to be displayed.
Before i start, I have included the files needed to run your own AppLoader so don't worry. :-) Also, I am an absolute beginner at flash so if I can do it, so can you!
I have also included the source files if you wanna make your own changes too :) ... I didn't write this program (and I can't find out who did - it's not in the readme on the SVN), but it's really easy to modify so here goes...
Getting Started:
1) Download the attached file below.
2) Once you have extracted the files, they should be added in your [b]'deploy'[/b] directory (e.g. C:\Multitouch\touchlib\AS3\src\deploy and make sure that the global flash security settings link to the swf or folder.
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html
(I selected my entire directory (/src) and added it to the site to make sure that any program I put in the 'src' or 'deploy' directory will run without an issue. )
Adding Apps / Editting AppLoader:
The Background image can be changed at any time by changing the file "\deploy\www\img\apploaderBack.jpg".
Applications can be added by editing the file "\deploy\www\xml\applist.xml"
I edited the applist.xml file and added the name of the program I wanted. Under the Category in the applist.xml file you will find the name of the program (e.g. WaterRipples) and the description to be displayed (Water Ripples for fun). The AppLoader will then look for the file “WaterRipples.swf” in the ‘deploy’ directory to try and load it when the load button is pressed. (NOTE: AppLoader only loads .swf files).
If you change the ‘name’ in the applist.xml file, then you need to change the .swf name in the deploy directory.
Here’s a sample of my applist.xml file:
Water Ripples for fun
Sometimes if though you do this, the app still wont load! I’ve found that a different build of the app (.swf) may fix this.
To get the screenshots and thumbnails to work, you’ll need to put the files under "\deploy\www\img\apps" They are (E.g. “WaterRipples_screenshot.jpg” and “WaterRipples.png")
You must make the name the same as the name listed in the applist.xml file for the images to be displayed. The Thumbnail size default is 72x72 and the Screenshot file is 395x295.
I’m running 2 types of Ripples. One is the default (Blue screen - ripples.swf) and the other is called WaterRipples (by wSatori), which can be customizable to display a video background, pebbles, still images...etc.
You can find it here:

DI Multi-touch Test 1 - ORION v2
This blog has been designed for a Multi-touch DI setup I made called ORION mt. Here are some apps to show the performance of the Multi-Touch interface. Please see the original post on Nui Group forums here:Monday, 12 May 2008
The Cars: Horizon Hobby.uk
Thanks to Horizon Hobby.uk, a Surface and Air R/C specialist, our group should be recieving 4 fantastic Mini T RTR's soon. These cars will suit this project to a tee, and help us crack on with the coding and electronics of the whole event. Brilliant!
Jobs For Wednesday
Here's a list of tasks our group needs to address for Wednesdays formative presentation.
LEDs on top of cars: Ping pong balls to diffuse light (Used to track cars). Power, ON/OFF with car
Circuits: On the cars and controllers
Podium: To allow players to view the arena. Location of exhibit
Camera: Resoloution, mounting.
Projectors: Angle of projection, height of projector, brightness
Max MSP Code: Colour tracking, immobilisation of cars, Quad core Handling
Bluetooth Arduino Boards: Circuits, power, code and functions
Trail Animations: Animation type (Fire/Ice/Fade/Gradient....etc)
Score Boards: On the play surface and projected on wall in front. (Tag cloud)
Size of Arena: Meters2. Materials, finalise colours and design
Slowing of Cars: Electro magnets?
Sound Effects: Environmental music, SFXs
Speed Limitation: Restrict trigger movement on controller
We'll be presenting this in a similar format to the first presentation, but this time the presentation must show the project in alot more depth, and a realistic roadmap towards the ROA deadline.

The Arena
Heres a mock up of an arena. A circular enclosure allows the cars to roam around the playsurface without getting stuck in corners unlike a square arena. The inner black circle will be the main 'floor', where most of the action will take place. The outer yellow and black striped ring warns players to try not to enter it, or they will be confronted by a barrier on the outside of the whole arena. Warning the players before they hit the barrier will help reduce the need to reverse the cars and hit their own tails in the process.

Illustration of possible positioning of the players
This illustration depicts how the players will be able to control the cars, each controller (joy pad) for the car will be placed on a small podium which will be standing on each side of the rail on the first floor of the broadcasting atrium... and from there the players will look down on the lower floor and control and move there specific car.

Cyclops
In order to track the remote controlled cars so a 'trail' can be projected, I originally thought infrared LEDs would be a good way to go (See 'The Presentation Post). Mounting the LEDs in a specific configuration on top of the cars would give the camera somthing to track and allow a trail to be projected along the path the car had taken. This setup would depend on a couple of things however. The camera mounted above would need to have a high enough resolution to distinguish the LED configurations and the cars themselves would need to power the LEDS, so more battery juice.
With abit of advice from Mr. Durrant and some research, Colour tracking would suit this project a little better. Painting the roof of the R/C cars different colours would allow the camera and Max MSP to track the cars without the need for LEDs or extra battery power.
After having a look on the Max Object website, i found an extension to analyze greyscale and color information from a live image. The plug-ins called Cyclops, which allows the resulting Cyclops data to control MIDI, audio, video and anything else that you can do in Max. Bad thing is that it costs 99 American Dollars, but i seems to do what we need. Well partly.
