Interactivity, Augmented Reality and Human-Computer Interaction

Igalia Interactivity specializes in the development of innovative ways of interacting with technology. We create immersive and engaging experiences by combining touchless, gestural and multiuser interfaces with advanced visuals and audio. The solutions we provide cover areas like art/multimedia installations, multisensorial stimulation rooms and augmented reality applications.

Technology is all around us, deeply integrated into our daily lives. However, our interaction with it is not always as natural as we would like it to be. Users are normally expected to learn how to use new technologies and adapt to them. In this scenario, we believe that the demand for simpler, more intuitive and natural interfaces will increase and accelerate in the future.

The Interactivity team at Igalia aims to help building a new generation of applications that feel more natural and fun to use. This  also includes taking technology out to the physical space, the surroundings that people already inhabit. We believe technology can and should integrate nicely and respectfully with our environment.

Current implementations and installations of the interactivity area rely in two software components specifically developed for this realm: SkelTrack and GFreenect.

SkelTrack is a Free and Open Source Software library whose goal is to provide easy to use human skeleton tracking while GFreenect is a wrapper for the Freenect library that allows controlling a Kinect device. It is written using Glib in order to ease the integration with GNOME technologies.

We are ready to hear about your specific needs, but here are some examples of how our team could help you in different scenarios:

  • For museums:

    Educative, entertaining and interactive applications can integrate into the  exposition areas to deliver a richer and more engaging experience for visitors.

  • For brands and stores:

    Advertising applications can complement your traditional campaigns and help you communicate successfully with your audience in a much direct and  powerful way.

  • For schools/education centres:

    Multi-sensorial stimulation rooms are found to be a very important complement to the traditional education programs for kids and people with disabilities, as they can significantly improve the way these people relate to others and their environment. Bringing open source to this area results in more affordable and flexible applications.

  • For geo-located content providers:

    Environment-aware augmented reality applications will make your users engage in a more natural experience, whether installed at a fixed location or delivered on the move.

Salutations Interactive Installation: Making of

Since the post about the Salutations Interactive Installation in the Museum für Kommunikation in Berlin, many people asked me for videos of the installation so we, the Igalia Interactivity team, came up with a better idea — a making of. …...


Skeltrack got an award

Last week, while I was busy in Berlin with an interactive installation, I received some good news: Skeltrack got an award in an innovation contest organized by the KNetworks project. From its own website, KNetworks “[...] is an open network …...

Avoid allocating new resources for calculating the extremas' averages

m skeltrack/skeltrack-skeleton.c Avoid allocating new resources for calculating the extremas' averages


Prevent division by 0 in coordinates conversion

m skeltrack/skeltrack-util.c Prevent division by 0 in coordinates conversion


Refactor the code to calculate an extremas' average

m skeltrack/skeltrack-skeleton.c Refactor the code to calculate an extremas' average It also prevents eventual division by zero of that code.


Refactor the way that the shoulders are retrieved

m skeltrack/skeltrack-skeleton.c Refactor the way that the shoulders are retrieved This abstracts the logic that was repeated for each of the shoulders and simplifies the code.
