Natural user interfaces: the prospect and challenge of touch and gestural computing

Natural User Interfaces show great promise to define new and potentially large niches of interactive computing. The promise of Natural Computing Interfaces (touch and gesture) stems from at least two sources -- the prospect of touch and gestural computing becoming as ubiquitous as currently dominant paradigms (e.g. GUI.) and technical breakthroughs. However, this new field of research and commercial development faces significant challenges. For example the challenge of developing a common terminology and framework while fostering innovation and creativity. The workshop will begin the process of addressing some of the challenges by (1) enumerating them, (2) listing potential ways to address them. As such our aim is to foster the evolution of NUI community of researchers and practitioners.
