...’s framework which describes the contextual factors arising from users’ interactions with the environment as well as “social others” to explain bodily interaction with non-keyboard controlled devices =-=[18, 19]-=-. Jacob et al. suggest that a “four lens view” provides sufficient detail and abstraction to analyse new systems that feature the human body. As such, our perspective of the human body is similarly st...

...ed by Ni and Baudisch, Graffiti ‘D’s were often misrecognized as ‘P’s [23]. Gestures Beyond some wearable devices, gestures have become a popular input mode for all sorts of Reality-Based Interaction =-=[18]-=-. As computers become more adept at interpreting the language of people (i.e., reality) they necessarily resort to input modalities akin to gestures. For years, immersive 3D environments have used fre...

...state, by only popping-up when being used, require directional accuracy instead of positional accuracy, and support gestural activation which is a desirable mode of interaction to support a “natural” =-=[14]-=- user interface experience. However, a marking menu design, which takes advantage of multitouch input, has not been investigated. Marking menus are a well studied menu design outside the multitouch do...

...he recently coined term “Natural User Interfaces” (NUI) highlights the intention behind these novel interaction styles: they build upon users’ pre-existing knowledge of the everyday, nondigital world =-=[4]-=- and hence lead to a more natural and reality-based interaction. However, the design and development of NUIs is not only conceptually but also practically a very challenging task. In contrast to the d...

... as Reality-based Interaction (RBI) provide guidance on how to utilize this huge design space for designing user interfaces that build upon the knowledge and experiences of people in the “real world” =-=[10,11]-=-. RBI is based on the assumptions that people’s interactions in the real world are highly practiced and robust and thus require little effort to learn and perform. In the design of reality-based inter...

However, Marshall points out a general lack of empirical evidence supporting the value of tangible interfaces for educational use [22], although some recent studies have sought to begin building bot...

...necker and Buur 2006]. TUIs are designed to take advantage of users‘ well-entrenched knowledge and skills of interaction with the everyday non-digital world, such as spatial, motor and social skills [=-=Jacob et al. 2008-=-]. By leveraging users‘ existing skills, TUIs offer the possibility of natural interfaces that are intuitive to use and learn. To date, TUI research shows a potential to enhance the way people interac...

...eractions with iCon should be explored in the future. As the physical world and virtual reality emerge, we believe that everyday objects and computational devices can form a new ecology. Jacob et al. =-=[11]-=- asserted that our iCon is a post-WIMP interface [24], and can be categorized as belonging to Naive Physics. This work can provide a foundation for intersecting augmented reality, tangible interfaces,...
