We describe an application of the cognitive dimensions (CDs) of notations framework to tangible user interfaces (TUIs)—interaction with computers using physical devices other than mice and keyboards. We are particularly interested in situations where the TUI is used to construct some information structure (a manipulable solid diagram) and where that structure is intended to specify computer beh...

Interactive systems based on augmented reality (AR) and tangible user interfaces (TUI) hold great promise for enhancing how to learn and understand abstract phenomena. In particular, they combine the advantages of numerical simulation and pedagogical support while keeping the learner involved in true physical experimentation. In this paper, we discuss three examples of such AR and TUI systems t...

Teaching children with intellectual disabilities is a big challenge for most parents and educators. Special education teachers use learning strategies to develop and enhance motivation for complex learning tasks. Literacy acquisition is an essential and life-long skill for a child with intellectual disabilities. In this context, technology can support specific strategies that will help children...

On tangible tabletops, Tangible User Interfaces (TUIs) can signalize their identity, position, orientation, and state by active infrared light. This provides rich interaction capabilities in complex, dynamic scenarios. If TUIs have to transfer additional high-resolution information, many bits are required for each update. This has a negative impact on the overall update rate of the system. In t...

In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users’ knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive ...

This study investigates semantic constraints affecting the order of motion morphemes in Mandarin multi-morpheme motion constructions (e.g., tui-hui recede-return). It classifies Chinese motion morphemes into three major types and proposes a “Scalar Specificity Constraint” to account for the order in multi-morpheme motion constructions. The constraint not only provides a better coverage of the d...

A common task in computer entertainment is the ability to interact with virtual 3D objects. Interacting with these objects using standard computer input devices such as a mouse and keyboard can often be a difficult task. For this reason, Tangible User Interfaces (TUIs) were developed to allow more natural interaction with complex virtual objects by manipulating physical objects in a familiar wa...

The East Lau Spreading Center (ELSC) and Valu Fa Ridge (VFR) comprise a ridge segment in the southwest Pacific Ocean where rapid transitions in the underlying mantle chemistry manifest themselves as gradients in seafloor rock geochemistry. We studied the geology and microbial diversity of three silicate rock samples and three inactive sulfide chimney samples collected, from north to south, at t...
