Figure 1. uniMorph contributes a rapid digital fabrication approach enabling designers to print custom shape-changing composites. With its multitude of capabilities for transformation and integration of electronics it facilitates a wide range of applications in shape-changing interfaces. ABSTRACTResearchers have been investigating shape-changing interfaces, however technologies for thin, reversible shape change remain complicated to fabricate. uniMorph is an enabling technology for rapid digital fabrication of customized thinfilm shape-changing interfaces. By combining the thermoelectric characteristics of copper with the high thermal expansion rate of ultra-high molecular weight polyethylene, we are able to actuate the shape of flexible circuit composites directly. The shape-changing actuation is enabled by a temperature driven mechanism and reduces the complexity of fabrication for thin shape-changing interfaces. In this paper we describe how to design and fabricate thin uniMorph composites. We present composites that are actuated by either environmental temperature changes or active heating of embedded structures and provide a systematic overview of shapechanging primitives. Finally, we present different sensing techniques that leverage the existing copper structures or can be seamlessly embedded into the uniMorph composite. To demonstrate the wide applicability of uniMorph, we present several applications in ubiquitous and mobile computing.

Cuboino establishes a new pathway that is not embodied in the marble, but adapts to the medium of its transmission. Signals can be received by multiple modules, creating more than one signal at a time. This allows signals to intertwine and thus create more dynamic and complex game-outcomes. AbstractCuboino is a computationally augmented physical toy system designed as an extension for the existing marble-game cuboro. It

The huge influx of mobile display devices is transforming computing into multi-device interaction, demanding a fluid mechanism for using multiple devices in synergy. In this paper, we present a novel interaction system that allows a collocated large display and a small handheld device to work together. The smartphone acts as a physical interface for near-surface interactions on a computer screen. Our system enables accurate position tracking of a smartphone placed on or over any screen by displaying a 2D color pattern that is captured using the smartphone's back-facing camera. As a result, the smartphone can directly interact with data displayed on the host computer, with precisely aligned visual feedback from both devices. The possible interactions are described and classified in a framework, which we exemplify on the basis of several implemented applications. Finally, we present a technical evaluation and describe how our system is unique compared to other existing near-surface interaction systems. The proposed technique can be implemented on existing devices without the need for additional hardware, promising immediate integration into existing systems.

We provide materials and simple fabrication processes that enable designers to rapidly prototype inflatables with simple hinging transformations or texture change. Furthermore, we introduce a customized hardware that enables designers to rapidly prototype inflatable fabric. The goal of this studio is to provide hands-on experiences of designing inflatable fabric as shape-changing materials and research on shape-changing artifacts. Basic knowledge of programming in Arduino is required. Participants should bring their own laptop for the studio.
