Näıve Physics: the common sense knowledge people have about the physical world. Body Awareness and Skills: the awareness people have of their own physical bodies and their skills of controlling and coordinating their bodies. Environment Awareness and Skills: the sense of surroundings people have for their environment and their skills of manip- ulating and navigating their environment. Social Awareness and Skills: the awareness people have that other people share their environment, their skills of interact- ing with each other verbally or non verbally, and their ability to work together to accomplish a common goal.

Tangible User Interface Showcase
Physical and embodied user interfaces Simone Mora email@example.com IDI, Sept. 17th, 2012
Agenda• Definition of physical user interface• Brief History• Frameworks• Research Showcase• Conclusions
What is a physical user interface? “An interface that rely on embodied interaction,tangible manipulation, physical representation of data and embeddedness in real space” (Hornecker&Buur, 2006)
What is a physical user interface? “An interface containing at least one interactiontechnique not dependent on classical 2D widgets such as menu and icons” (Van Dam, 1997)
History• The emergence of physical interfaces is closely related to the adoption of ubiquitous computing technologies• Instead of creating “Virtual Words” or building on the WIMP (Windows, Icons, Mouses, Pointers) paradigm, computation should enrich the real world with information from the digital domain
Frameworks• GUIs are really flexible since they can represent a variety of information by decoupling representation from control• The key idea of physical computing is to give physical form to digital information. However that makes the tangible part more specific and less flexible.• So, the challenge is: how can you mix both?

Reality Based Interaction (Jacob et al.)• Descriptive framework• Many new interaction styles are designed to take advantage of users’ skills and experience of interacting with the real non-digital world• Interaction with information becomes from a segregated activity that takes places at a desk to a fluid free form activity that takes place into the real world
Reality Based Interaction (Jacob et al.) • Jacob et al. identified four themes of interaction with the real world that can be leveraged by physical interfaces:Jacob, R. et al., 2008. Reality-based interaction: a framework for post-WIMP interfaces. Proceeding of the twenty-sixth annual SIGCHI conference onHuman factors in computing systems, pp.201–210.
Main Themes (technology) • Tangibles (graspables) • Tabletops & Interactive surfaces • Augmented Reality • Whole-body interaction • Ambient interfacesIllustrations adapted from: Shaer, O. 2009. Tangible User Interfaces: Past, Present, and Future Directions, 2009 and http://dub.washington.edu/pubs

Physical Interfaces - Pros• May increase usability• May increase enjoyment• Allows for (user-side) multitasking• Allows for interaction in the periphery• Support face-to-face social interaction (Hornecker&Buur, 2006)• Can leverage users’ knowledge and skills of interaction with the everyday, non-digital, work (Jacob et al., 2008)
Physical Interfaces - Pros• (Almost) unexplored area of research, you can be a pioneer!
Physical Interfaces - Challenges• Requires not only designing the digital (software) but also the physical (hardware) and the interrelations between the two (affordances)• Physical interaction is socially and culturally situated (Hornecker, 2011)
