“…Moreover, with the second language l 2 , the state of the button or of the foot pedal does not reflect the state of the system (clutched or declutched). This fact is known with the bounce-back buttons that are used for computer on/off switches [2]: they typically have to rely on an indicator light to represent the state of the computer.…”

Manual assembly of virtual 3D objects is required in several application fields. We focus on tangible user interfaces which offer the opportunity to the user to perform virtual assemblies efficiently and easily. In each hand, the user manipulates a tracked prop, and the translations and rotations are directly mapped to the corresponding virtual object. However, with such interfaces, both hands are requisitioned, and the user cannot drop the props without changing the action or the expected results. We list and discuss the choice of four possible modalities to activate/deactivate the assembly modality: vocal modality, gestural modality, buttons, and foot pedals. We conclude that when using the foot pedals, the user's gesture is closer to the real-world behaviour.

The physical interaction aspects of embedded systems have been neglected in comparison to internal software issues in the software engineering field. Physical interfaces suffer from interaction complexities leading to usage difficulty and poor acceptance by the end-users. Meanwhile, the usability techniques focus on the overall usability issues while overlooking the in-depth physicality aspects of the interface and interaction. This study proposes a physicality-focused quantitative evaluation method to assist the embedded system developers in managing the interaction complexities of their products. The acceptance of the embedded system developers towards the proposed method was assessed by means of a user study. The results suggested their strong acceptance. The aim of this study is to re-emphasise the natural physical aspects of embedded system interfaces leading to intuitive interaction.

“…exposed state, bounce-back, compliant interaction). This analysis and the early stages in developing a diagrammatic notation has been reported previously [GhD03,GhD05] and a later paper introduced a more explicitly formal specification to give a level of semantics to the diagrams and also allow formal statements of some properties [DGR07]. The current paper adds to this picture refining some of the formal expression, engaging in more detailed discussion of its implications, extending the work through a practical case study with product designers, and reflecting on use in novel device design.…”

Abstract. This paper explores the formal specification of the physical behaviour of devices 'unplugged' from their digital effects. By doing this we seek to better understand the nature of physical interaction and the way this can be exploited to improve the design of hybrid devices with both physical and digital features. We use modified state transition networks of the physical behaviour, which we call physiograms, and link these to parallel diagrams of the digital state. These are used to describe a number of features of physical interaction exposed by previous work and relevant properties expressed using a formal semantics of the diagrams. As well as being an analytic tool, the physigrams have been used in a case study where product designers used and adapted them as part of the design process.
