abstract = {We present Augmented Displays, a new class of display systems directly combining high-resolution interactive surfaces with head-mounted Augmented Reality. This extends the screen real estate beyond the display and enables placing AR content directly at the display's borders or within the real environment. Furthermore, it enables people to interact with AR objects using natural pen and touch input in high precision on the surface. This combination allows for a variety of interesting applications. To illustrate them, we present two use cases: An immersive 3D modeling tool and an architectural design tool. Our goal is to demonstrate the potential of Augmented Displays as a foundation for future work in the design space of this exciting new class of systems.},

abstract = {We demonstrate a simple and accessible method for enhancing textiles with custom piezo-resistive properties. Based on in-situ polymerization, our method offers seamless integration at the material level, preserving a textile's haptic and mechanical properties. We demonstrate how to enhance a wide set of fabrics and yarns using only readily available tools. During each demo session, conference attendees may bring textile samples which will be polymerized in a shared batch. Attendees may keep these samples. While the polymerization is happening, attendees can inspect pre-made samples and explore how these might be integrated in functional circuits. Examples objects created using polymerization include rapid manufacturing of on-body interfaces, tie-dyed motion-capture clothing, and zippers that act as potentiometers.},

To support rapid fabrication in a sketching-like fashion, we developed a handheld dispenser tool for directly applying continuous functional tapes of desired length as well as discrete patches. We demonstrate versatile compositions techniques that allow to create complex circuits, utilize commodity textile accessories and sketch custom-shaped I/O modules. We further provide a comprehensive library of components for input, output, wiring and computing.

abstract = {While standard VR controllers lack means to convey realistic, kinesthetic impressions of size, resistance or inertia, this demonstration presents Drag:on, an ungrounded shape-changing interaction device that provides dynamic passive haptic feedback based on drag, i.e. air resistance, and weight shift. Drag:on leverages the airflow at the controller during interaction. The device adjusts its surface area to change the drag and rotational inertia felt by the user. When rotated or swung, Drag:on conveys an impression of resistance, which we previously used in a VR user study to increase the haptic realism of virtual objects and interactions compared to standard controllers. Drag:on's feedback is suitable for rendering virtual mechanical resistances, virtual gas streams, and virtual objects differing in scale, material and fill state. In our demonstration, participants learn about this novel feedback concept, the implementation of our prototype and can experience the resistance feedback during a hands-on session.},
