TISCH Framework - Release 2.0 "Better Late Than Never" ====================================================== "Tangible Interactive Surfaces for Collaboration between Humans" The TISCH framework supports cross-platform development of multitouch applications. For details on the underlying architecture and source code documentation, please visit the Sourceforge website: http://tisch.sourceforge.net/ Highlights ---------- - ready-to-use multitouch widgets based on OpenGL - reconfigurable, hardware-independent gesture recognition engine - support for widely used (move, scale, rotate..) as well as custom gestures - hardware drivers for FTIR, DI, Wiimote, Kinect.. - native use of popular TUIO 2.0 transport format - cross-platform: Linux, MacOS X, Windows (32 and 64 bit) - cross-language: C++ with bindings for C#, Java, Python Directory Layout ---------------- libtisch2-2.0/ calibd/ Calibration Layer drivers/ Hardware Abstraction Layer (HAL) gestured/ Generic Gesture Recognition Layer libs/ various helper libraries & wrappers for C#, Java, Python scripts/ build scripts widgets/ OpenGL-based Widget Layer Quick Start ----------- If you only have a mouse and want to give it a try: 1. run "demo -m" (enables mouse emulation mode) If you have a camera-based input device, e.g. an FTIR table or a Kinect: 1. run "touchd -V -c example.xml" (this is the most basic mode, just tracks bright blobs) 2. run "calibtool -f" and follow the instructions (this is necessary only once) 3. run "calibd", if not already running 4. run "demo" Notes about demo programs ------------------------- All of the demo programs (picview, slideshow, graph, demo) accept '-m' as first parameter, switching them to mouse emulation mode. picview and slideshow take a list of PNG images to display as additional parameters. In mouse emulation mode, you can move elements with click-and-drag. Rotate them by clicking any mouse button and scrolling the mouse wheel. Scale them by additionally pressing CTRL while using the wheel. NOTE: if you are running an X server with XInput2 support (commonly known as MPX), you can actually use multiple mice to emulate multitouch fairly well. Building & Requirements ----------------------- Windows (tested with Visual Studio 2008 on Windows XP and Windows 7) Requirements: - Windows SDK 6.1 or greater (for DirectShow camera input) - freeglut 2.4.0 or greater (preferably 2.6.0) You need to have the Windows SDK & freeglut 2.4.0 or greater installed. By default, the include paths point to a "freeglut" directory in the same parent folder as the "libtisch-1.0" directory and to the default Windows SDK install directory. If you installed your libraries somewhere else, you may need to adjust these paths. To do so, - open libtisch.sln in Visual Studio. - Go to "Property Explorer". - Expand the tree until you see the "common" property page and open it. - Click on "User Macros" and enter the correct path for "freeglut". The same applies to "winsdk", which should point to the location where your Windows SDK (formerly Platform SDK) is installed. Then, just select the Debug or Release config and build the solution. All libs and binaries should be created in the appropriate output directory. Linux (tested with gcc 4.4.4 on Ubuntu 10.10 and gcc 4.5.2 on Ubuntu 11.04) MacOS X (tested with gcc 4.0 on MacOS X 10.5 and gcc 4.2 on MacOS X 10.6) Requirements: - freeglut 2.4.0 or greater (Linux only - use "apt-get install freeglut3-dev") - libdc1394 2.0.0 or greater (optional - for Firewire cameras) If you want to use a Firewire camera, install libdc1394 v2.0.0 or greater first. Take care that pkg-config knows about it. For Linux, you should also have installed a GLUT library (preferably freeglut 2.6.0 or greater) in your system include/library paths. Then, simply run "make all && make install" to build all binaries and put them into build/{bin,lib}/. Don't forget to add the lib directory to the library path (LD_LIBRARY_PATH on Linux, DYLD_LIBRARY_PATH on MacOS X). You can also run "make" without arguments to review the other available parameters. If you wish to install the binaries to a system directory such as /usr/local, set the DESTDIR (installation directory) and PREFIX (runtime prefix) variables when running make, e.g. as "make DESTDIR=/tmp/ PREFIX=/usr/local/ install". The default method for camera access is through libdc1394 with Video4Linux as fallback. Note that camera access has been tested with several different types of Logitech QuickCams (both PWC- and UVC-based USB types) and with Pointgrey FireflyMV Firewire cameras. Known Issues ------------ - Documentation is lacking - check the Sourceforge Wiki for more information. - The example configuration files are rather convoluted. - The graphical frontends also accept TUIO 1.0 data, but the object types may or may not match. Check the Wiki at www.tuio.org for details.
