Collaborative technologies are pervading every field of the modern society, influencing the way we act, work and socially interact. Collaboration technologies and systems in healthcare and in general in biomedical fields create new ways to develop, provide and improve the quality of health services. The potentialities disclosed by collaborative technologies range from education to direct clinical applications (including home monitoring, telerehabilitation, remote surgery, etc.), passing through remote consultation and second opinion, electronic health record and patient’s data sharing, development of social virtual spaces and communities for patients, and many more. Collaborative technologies in healthcare are necessary for the development of telehealth and telemedicine services but can also be used to facilitate both inclusion and participation for disadvantaged categories such as the elderly, the people with disabilities, etc. They cut costs while increasing access and providing convenience. Broadening to the biomedical field, including biomedical research, collaboration technologies are also used in bioinformatics and life sciences. CoHeB workshop aims at providing a scientific forum for disseminating and discussing the latest advances and research results in the development and/or application of collaboration technologies and systems in healthcare and biomedical fields. The main objective is to bring together researchers, scientists as well as practitioners from academia, industry, government, and research institutions in a multidisciplinary environment where novel ideas and recent achievements can be presented, fostering the creation of new networks and collaborations among ICT researchers and health professionals. The workshop will include a keynote speech, contributed paper sessions and demos, as part of the main CTS2014 Conference.
