Free interaction software for linux

Medical Imaging Interaction Toolkit (MITK) is currently under active development, and aims at supporting the development of leading-edge medical imaging software with a high degree of interaction. It combines vtk, itk and the pic-based-libraries of the Div.
Main features:
- multiple, consistent views on the same data. For example, when you have three orthogonal 2D-views and a 3D view and data consisting of a green surface, the surface will be visible and green in all views (as contour lines in 2D, as a surface in 3D), and when you move the surface, it will move in all views. When you try to realize this with basic vtk, you will need to coordinate the position/orientation/color/... of all the views somewhere in your program - exactly this can mitk do for you.
- interactions that create and/or modify data (not only actors as in basic vtk)
- complex interactions with multiple states, e.g., for interaction with active contours
- undo/redo of interactions
- organization of data objects in a tree at run-time, e.g., to represent logical dependencies (e.g., a heart cavity is a part of the heart) or to control the rendering process
- additional properties of arbitrary type can be assigned to data objects contained in the data tree
- visualization and interaction with 3D+t data (basic vtk can handle only 3D data and itk is not for visualization and interaction)
- although mitk is mainly a toolkit and not an application, it offers some support on the application-level, e.g, for structured combination of modules (so-called functionalities), e.g., for combining and switching between one functionality for segmentation and another for registration.
Enhancements:
- New functionalities: IsoSurface, ViewInitialization and Measurement.
- Support for ITK 2.4-2.8, VTK 4.4 and 5.0.
- Lots of bugfixes and improvements, e.g. interaction for rotatable slices.

PrefGenerate is a script used to configure user accounts without the need for user interaction.

PrefGenerate sets up a complete Mozilla Firefox and Mozilla Thunderbird profile, as well as the window manager Icewm. Its currently used in an enviroment with over 8000 users.

Qemulator provides an easy and fast to use image and device management, a "My machines" list and interactive job control.

It comes with a list of all running jobs from where you can open the contol panel for each job and performing on demand action. Full interaction for mounted volumes, usb devices, keyboard and mouse interaction, screenshots, wave capture and save/restore machine state and open vnc viewer is provided.

The project is still under development. Current version should run stable on most Linux machines providing allmost all functions of qemu, but there are still some works to do.

Object::Mediator is a generic object persistence framework.

SYNOPSIS

package Persistent;

use base qw( Object::Mediator );

__PACKAGE__->mk_attr ( qw(foo bar) );

sub _set_id {
my $self = shift;

my $id = generate_identity();

$self->identity( $id );
}

sub _insert {
my $self = shift;

$db_handle->insert ( $self->id, $self->foo, $self->bar );
}

sub _update {
my $self = shift;

$db_handle->update ( $self );
}

sub _delete {
my $self = shift;

$db_handle->delete ( $self->id );
}

sub _select {
my $self = shift;

my ( $foo, $bar ) = $db_handle->select ( $self->id );

$self->foo ( $foo );
$self->bar ( $bar );
}

Object::Mediator attempts to be simple and fairly minimalistic object mapping framework. Main aims of development were: usage simplicity, end user transparency, database independency and minimization of database interaction with some kind of in-memory object state control system.

Authenticated User Community project is a CGI-based intranet system for K-12 settings.

AUC (Authenticated User Community) is an intranet system designed for use in an educational organization but is also useful in many other settings.

It offers the ability for users to have a uniform web-based interface to discussion forums, e-mail (similar to hotmail, etc.), file management, and a searchable user database.

Also, "Interactive Classrooms" provide a means for students and teachers to have a web-based extension to their in-class interaction.

The system runs from a C-based monolithic CGI script. MySQL is used for database storage. Also, the web-based mail client supports MIME parts/attachments, IMAP, mbox, and multiple mail folders.

Zinc is a Tk widget developed with Perl/Tk, Tcl/Tk and Python/Tk bindings. Zinc widgets are very similar to Tk canvases in that they support structured graphics.

Graphical items can be manipulated, and bindings can be associated with them to implement interaction behaviors. But unlike the canvas, zinc can structure the items in a hierarchy, and has support for affine 2D transforms.

Clipping can be set for sub-trees of the item hierarchy and the item set is quite more powerful, including field-specific items for Air Traffic systems.

Zinc is fast enough to allow the implementation of 2k2k radar displays with smooth animations. It is structured enough to allow the implementation of direct manipulation desktop GUIs.

ETH Lecture Communicator is a tool to improve classroom interaction between an instructor and their students.
ETH Lecture Communicator enables the instructor to create and carry out in-class online assessments, and facilitates organized instant communication for large classes.
It is intended to improve the overall quality of a lecture by providing the instructor with continuous feedback on the students understanding of the material.
Enhancements:
- The remaining known bugs were fixed.
- The most annoying of these was the seemingly random resending of no longer existing questions.
- Some GUI ugliness was cleaned up as well, especially for Linux systems.
