ofxKeyboard 0.3 ( openFramework version of Tiper3)

Posted on October 19, 2010 by Patricio González Vivo

I start this project in Processing for a multiTouch sketch. The idea was to make a keyboard map maker in order to make my own distribution of keys for a super configurable tools. So, you can make your owns keyboards or control remotes for any multiTouch/TUIO projects.

So I wrote to different sketches (one for the keyboard and the other for the maker)

Then I migrated to openFrameworks. It still use the same type of config file (one that ends with .kbd) for storing the key distribution. For it, uses polar geometry in order to let it be rotate, scale and drag and continue to be 100% functional.

On openFrameworks uses ofEvents to handles the pressed keys and need the next addons:

- ofxOsc

- OfxTUIO

- MSAcore

You can download the code and examples at: http://code.google.com/p/ofxkeyboard/

[ Note about the .kbd: The first line have the information of the keyboard. Center x and y, the width and height. And the other ones are the keys with their position (on radio and angle), width and height. ]

New version of Tiper and MapMaker

Posted on October 16, 2010 by Patricio González Vivo

Thanks to Bernardo dos Santos for the mail. He was using the Tiper2 and he have some problems with the tuioZone. I take the opportunity to translate the code and comment it in english.
I also clean some parts of the code and modify the first part of the .kbd files in order to store there the information abouth the border and center of the keyboard.

First you have to use the Tiper3MapMaker in order to draw the distribution of the keyboard you want to use. I already made a map.kbd file. Open it with a text editor, explore, modify or erase all the information. Then draw a new one. For default you it always save it on the map.kbd file.
The interesting thing of it is that in this example I use a photo of a mac keyboard but you can use what ever you want. Each time you press a key it will create one with the same letter. But then you can change it using a text editor and put there a word for example: POWER, VOL +, VOL – , etc…. in order to make a RemoteControl.

After created you map.kbd file move it to the data folder of Tiper3. With it you give it life and functionality. You can place it what ever you want and rotate. It use polar geometry instad of pushing and poping the matrix, so it always work no mater how many times you rotate and move it.
I commented some lines here use the TUIO library in order to make it work over a multitouch surface. You can download the library from tuio.org, look at the videos I have about making a cheap moultitouch surface to start playing with it and using as a virtual keyboard.

Look at the “check” funtion of the Keyboard Class in order to know how to know wich key is pressed and start thinking how can became part of you projects.

If it works for you, or if you make some changes, or if you have doubts, please let me know in order to make it a better tool.
