This paper presents the continuous work towards the development of an interface for music mixing targeted towards expert sound technicians and producers. The mixing interface uses a stage metaphor mapping scheme where audio channels are represented as digital widgets on a 2D surface. These can be controlled by multi touch or by smart tangibles, which are tangible blocks with embedded sensors. T...

Tabletop environments are ideal for collaborative activities that involve moving and arranging objects. However, manipulating 3D virtual objects through the 2D interface is challenging because users’ 2D actions must be translated into 3D actions. We explore the use of touch and tangibles to aid collaboration and 3D object manipulation. Our user study shows that using touch and tangible interact...

We present Tangible-Tango, a system which enables users to fabricate new tangibles and their equivalent 3D virtual models. Thus the cognitive load required to understand and interact with virtual models is reduced. Users build new models by iteratively creating and assembling physical models. Each physical model has an associated virtual model. The new models, both virtual and tangible, can be ...

Tangible user interfaces play an important role in blended interaction concepts. In this paper we explore the design space of tangibles made of translucent materials and how they can be used on interactive displays; we investigate design aspects such as materials, form factors and interaction techniques and review existing translucent tangibles in literature accordingly. We also present three o...

The articulation of practice and theory is a central problematic in a dual apprenticeship system that combines working in a company and attending courses at school. Design problems are proposed by teachers as a way to address theoretical concepts in a practical context. The difficulties encountered by apprentices while creating paper based sketches motivated the development of a tabletop wareho...

Current design guidelines for conventional tangible systems suggest that the representational significance of tangible tokens is an important consideration in the design of tangible interaction, especially in collaborative contexts. Such advice might be assumed to imply that nomadic systems that employ improvised tokens are liable to have highly impaired usability. In this paper we describe Kol...

In TUIs, physical/digital conflicts can occur when the digital model does not match the model implied by the spatial layout of tangibles. We show how tangible tabletop interfaces (TTI) can be modified to allow robot movement of tangibles, thereby avoiding conflicts. We present RoMo, an open source Java library that allow existing TTI applications to perform robot movement, and demonstrate its f...
