The overall goal of IRIS is to provide a natural interaction communication platform accessible and adapted for all users, particularly for people with speech impairments and elderly in indoor scenarios.
Human-Computer interaction with this platform will adopt the principles of universal design and natural user interfaces such as speech, silent speech, gestures, tactile and haptic devices, pictograms, animated characters and personalized synthetic voices.
The platform will provide a set of services that allow easy access to social networks, friends and remote family members, fighting social-exclusion of people with special needs or impairments. Application of these features will be performed in the context of serious games, virtual reality environments and assisted living scenarios. We will also explore the use of personalized avatars (that resemble with the user) in asynchronous human-human and human-machine communications, in situations where the user has lost his/her voice and in scenarios where it is not possible to have a video signal transmission due to low bandwidth or privacy reasons.
Biometrics will complement the platform, in the sense that authentication and authorization are fundamental aspects for assuring access security to personal information in a natural way.

Iris is the personification of the rainbow and messenger of the gods. Iris travels with the speed of wind from one end of the world to the other, linking the gods to humanity. Iris carries messages from gods to gods, and from gods to men, appearing in front of the people in a human form in order to reveal the orders to them.
