The Ubiquitous Computing (UC) idea envisioned by Weiser in 1991, has recently evolved to a more general paradigm known as Ambient Intelligence (AmI). Ambient Intelligence then represents a new generation of user-centred computing environments aiming to find new ways to obtain a better integration of the information technology in everyday life devices and activities.

AmI environments are integrated by several autonomous computational devices of modern life ranging from consumer electronics to mobile phones. Ideally, people in an AmI environment will not notice these devices, but they will benefit from the services they provide them. Such devices are aware of the people present in those environments by reacting to their gestures, actions and context. Recently the interest in Ambient Intelligence Environments has grown considerably due to new challenges posed by society, demanding highly innovative services such as vehicular ad hoc networks (VANET), Ambient Assisted Living (AAL), e-Health, Internet of Things and Home Automation among others.

The main focus of this edition of the UCAmI Conference will be "Ubiquitous Computing & Ambient Intelligence: Context-Awareness and Context-Driven Interaction". Meanwhile, the edition of the IWAAL Conference will be focused on "Ambient Assisted Living and Active Aging".

CLIHC (Congreso Latinoamericano de la Interacción Humano-Computadora) aims to bring together people's diversity, culture, geography, history and Latin America perspectives from professionals in the area of Human-Computer Interaction (HCI). This event had its origin in Rio de Janeiro 2003 – Brazil, following editions in Cuernavaca 2005 - Mexico, Rio de Janeiro 2007 – Brazil, Mérida 2009 - Yucatán in Mexico, Porto de Galinhas 2011 - Brazil.

The Latin American and the International HCI communities are invited to exchange ideas, methods, approaches and techniques that aim designing interactive user experiences. In consonance with previous editions, we believe that in the field of HCI, not only we must come to a technology that can be used and appreciated by as many people as possible, but also to promote intercultural exchange and cooperation between people with different backgrounds and needs
