Free application user interfaces software for linux

General Graphics User Interface is an effort to produce a common graphical user interface for any command-line program.

It uses a wizard-like input front end to collect the information needed. It then calls the desired program automatically with all the necessary options.

The user is able to point&click on various options and select them in a convenient way. In order to create a new user-interface, a user doesnt need to know a programming language, since there is a graphical editor for new GGUI "scripts".

RULI stands for Resolver User Layer Interface. Its a library built on top of an asynchronous DNS stub resolver. RULI provides an easy-to-use interface for querying DNS SRV resource records. The goal is to promote wide deployment of SRV-cognizant software. RULI aims to fully support SRV-related standards. There are bindings for PHP, Perl, Guile/Scheme, Java, and Lua. IPv6 is supported.

Now you can understand the benefits of SRV records and please see how RULI can help you.

SRV records are more complex than A records

Handling DNS SRV is not as simple as to deal with ordinary address records. When one performs a query for A records by calling gethostbyname(), he gets a list of addresses which should be contacted in the same order as they were received. For SRV records, there is an additional logic that must be applied to the records, based on their weight and priority, to discover the correct sequence for contacting them.
RULI can handle SRV records for you

The SRV logic is described in RFC 2782. Those who intend to use SRV benefits in their application are expected to implement that exact behavior. RULI can help here: it automatically performs all the SRV logic for you.
Keep focus on your application logic

Application developers probably want to spend time on their business logic; not dealing with the details of the DNS protocol or implementing the SRV specification.

RULI is a tested framework designed to properly fetch SRV records. It saves you time and head aches.
RULI is free as in free beer and in free speech

reacTIVision is an open source, cross-platform computer vision framework for the fast and robust tracking of fiducial markers in a real-time video stream. reacTIVision project was mainly designed for the rapid development of table-based tangible user interfaces.

Its tracking core is using Ross Bencinas fidtrack library which is basically a newer high-performance implementation of Enrico Costanzas original d-touch concept. This framework was developed by Martin Kaltenbrunner et.al. at the Music Technology Group, IUA, UPF in Barcelona, Spain as part of the reacTable* project, a novel electro-acoustic musical instrument with a tangible user interface.

reacTIVision is a standalone application, which sends OpenSound Control messages via a UDP network socket to any connected client application. It implements the TUIO protocol, which was specially designed for transmitting the state of tangible objects on a table surface. This framework includes a set of free example client projects for various programming languages, which serve as a base for the easy development of tangible-user interface applications.

The reacTIVision application compiles and runs under the follwing operating systems: Win32, MacOS X and Linux. Under Win32 it suports any camera with a proper WDM driver, such as USB, USB2, FireWire and DV cameras. Equally under MacOS X any such camera supported by QuickTime will work in reacTIVision. Under Linux, FireWire cameras are best supported, as well as a few Video4Linux USB cameras.

NEW: Support the reacTIVision project and buy T-Shirts, posters and other merchandise featuring the reacTIVision fiducial symbols in our web-shop! All designs on these products can be recognized and tracked by the actual reacTIVision software.

Application Handling

Before starting the reacTIVision application make sure you have a supported camera connected to your system. The application can and will not work at all without a camera. Under Win32 and MacOS X the application will ask to select and configure the camera upon startup. Under Linux the camera will be selected automatically. Once configured the application will show a video window with the current camera image in black&white.

Pressing T will show the binary tresholded image, pressing the N key will turn the display off, which reduces its CPU usage significantly!

Pressing the S key will return to the original source image. For convenience and debugging porposes hitting the R key saves a raw image frame, while hitting the B key will save an image in the BMP format.

The P pauses the image analysis completely, hitting ESC will quit the application. The F key toggles the diplay of FPS info in the titlebar. In order to produce some more verbose debugging output, hitting the V key will print the currently recognized symbols to the console.

Command Line Options

The reacTIVision application per default sends the TUIO messages to port 3333 on localhost (127.0.0.1)

In order to change these parameters you can invoke the application with the -h [ip-address] and -p [port-no] options.

reacTIVision needs a so called "tree file" in order to function properly. The default "all.trees" is included and loaded automatically. If you want to use you own tree file you can invoke the application with the -t [tree-file] option.

Optionally if you dont want to analyze the complete image - for example in a square or round table setup - the application can mask a part of the video image with a black region, which speeds up the segmentation algorithm. In order to apply this mask You can invoke the application with the -m [square,circle] option.

Applying the -h or -help option will print a usage message to the console.

Calibration and Distortion

Some tables, such as the reacTable are using a convex mirror in order to increase the area visible to the camera at a minimal distance. This mirror as well as a fish-eye lens unfortunately distort the image. reactIVision includes a correction algorithm, which corrects this distortion with the help of a so called "grid file". These grid files can be generated during a prior calibration process.

To calibrate reacTIVision invoke the application with the option: reacTIVision -c 9 -g [grid_file]

In order to use the this calibration invoke the application with: reacTIVision -g [grid_file]

Dolda Connect is a modular P2P filesharing client built around the Direct Connect model. It supports most of the latest features of the DC protocol.
It runs in client/server mode with a well defined protocol, allowing extensibility, flexibility, and multiple detachable user interfaces. Dolda Connect also has an optional multi-user mode.
For the average user, this yields two primary advantages:
- The daemon can be made to run on another computer, which can be on all the time (a server, if you will), while the user interface can run on the users workstation. That way, the user can turn off his workstation at night, while the server will continue all transfers in progress during that time.
- A user can control his daemon from another location, such as from work, school, a friend, etc.
This architecture also has many other advantages in store for the more advanced users; since the user interface communicates with the daemon using a well-defined protocol, other user interfaces can be written, such as an automatic downloader, a chatbot, etc. It is also designed for secure multiuser operation.
Enhancements:
- A GUI configurator tool was added.
- Portability issues were fixed so that it works on AMD64 now.
- The documentation was improved.
- The usual slew of minor bugs were fixed.
