As users demand more multimedia, interactive, on demand and better quality services, the need to have wider bandwidths becomes more apparent. To overcome this fact, the optical communications are considered a good choice to fill these needs

In recent years, human-computer interfaces have changed dramatically thanks to the maturity of innovative technologies such as image, voice or information analysis from different sensors as accelerometers. In fact, some successful market products have taken advantage of these technologies: Nintendo Wii and Xbox Kinect are good examples in the field of video games. More recently, several BCI (brain computer interface) devices have appeared in the market such as Emotiv EPOC or Neurosky MindSet

As part of his PhD, Enrique Sánchez, researcher at Gradiant's Multimodal Information Area, has completed his half-time as a visitor scholar in the Human Sensing Lab at the Robotics Institute (Carnegie Mellon University, CMU), one of the most important robotics institutes in the world.

Digital television systems and, particularly, the different DVB standards for satellite, terrestrial and cable transmission are widely extended in Europe as well as in many countries of Africa, Asia and Oceania. In parallel to this, over the last years there has been a relevant increase in broadband connections at Home. The combination of these two facts implies the creation of an important potential market, with millions of users, for applications that integrate these two technologies.
