Research on Data Physicalization
What if data moved off the screen, with 3D physical shape and materiality? Ongoing research investigates Data Physicalization - physical artefacts whose geometry or material properties encode data. Building on past experience from Trevor Hogan's 'Tactile Data' PhD we have pursued this further, so far in 2 student projects, as Hannes Waldschütz' research focus.

DFG Project FluidData - The User Experience of Novel Pneumatic Shape-Changing Interfaces for Dynamic Data Physicalization
March 2020 our new DFG Project FluidData started. This investigates the potential of dynamic shape-changing interfaces for data representation. The project has a constructive-technical and an empirical strand. Project staff: Hannes Waldschütz and Rosa van Koningsbruggen.
On a constructive-engineering level, we will realize controlled shape change via pneumatically actuated (fluidic) membrane structures from textile/elastomeric material (inflatables) and explore the novel options this offers for shape-change and interaction. For this, we build on and collaborate with Kristian Gohlke's ongoing PhD work. The empirical focus of this project is on the user experience of data physicalization (especially with shape-change). While other research teams have begun investigating performance and accuracy in Data Physicalization, we believe that beyond pragmatic and utilitarian factors (i.e. usability), there are qualities and benefits related to user affect, sensation and meaning, i.e. UX. For some usage situations, this might be more important for increasing engagement and empathy with data. We will thus investigate terms of qualities and interpretations ascribed to a representation, as well as sense-making processes evoked, including the potential to raise empathy.

RethiCare (funded by VolkswagenStiftung), starting April 2019 (3 year project)
RethiCare (Rethinking Care Robotics) will be led by the HCI group and is a joint interdisciplinary project with BUW's Product Design area (Prof. Wolfgang Sattler), the University of Southern Denmarks Robotics group at The Maersk Mc-Kinney Moller Institute (Prof. Norbert Krüger) and sociologist Dr. Andreas Bischof at TU Chemnitz. RethiCare will explore the design space of non-anthropormorphic, robotic helper machines and devices (which, for instance, integrate with everyday objects and furniture) for the context of care homes.
To re-shape research and design practices and to develop alternative visions for robots in care, new interdisciplinary collaborations and new methods of design and evaluation are needed. The project's interdisciplinary constellation will enable us to re-think from the ground up what care-robotics should look like and ‘do’, using contemporary design methods in a rapid prototyping, design-driven approach. It will apply a user-centered, creative design and development approach in close collaboration with users (2 care institutions as associated partners), guided by principles of universal design, flanked with an integrated science-technology-studies perspective.

Re-thinking CareRobots (Planning Grant), VolkswagenStiftung
In January 2018 we received a small grant from VolkswagenStiftung aimed to support preparation for a full funding proposal on 'rethinking care robotics' (which was successful). As part of the preparations, we (Prof. Sattler, Product Design program and us) co-taught a student project on technology in care. Our future project partners traveled to Weimar for proposal discussions, and were also invited into the student project and for the Bauhaus.Interaction Colloqium, all helping us to immerse deeper into the topic. We also attended a conference on care technology ('Zukunft der Pflege') in Oldenburg with the entire project group, which was a great experience for all.
ELIXIER - BMBF Project 'Erfahrungsbasiertes Lernen durch interaktives Experimentieren in erweiterten Realumgebungen'
The BMBF Project ELIXIER has recently started (May 2016). ELiXIER will develop an augmented experimental lab workbench that provides context-oriented tutorial assistance (via embedded projections, sound output, etc.) and supports teachers in setting up experiments for class. The system will enable intelligent connection of digital learning portfolios and practical lab experiments via a web-based infrastructure (seamless smart lab) so that learners can review their practical work anytime, anywhere in an interactive way.
The project collaborates with industry partners and research institutions, and has several strands, from the technical infrastructure development, sensor tracking of experiment data, to didactical assistance, learning effectiveness and usability of augmented learning environments. The role of BUW in this project focuses on usability-oriented design and evaluation of augmented environments.

Exploring Bio-Inspired Soft Fluidic Actuators and Sensors for the Design of Shape Changing Tangible User Interfaces.
Kristian Gohlke's PhD investigates fluid actuators (also known as soft robotics), mainly in form of pneumatically actuated soft or malleable material mechanisms as well as the use, application potentials and the limitations of such systems for interaction design. By contributing to a novel category of interfaces that are malleable, inherently capable of isotropic shape change and mechanically compliant, the research further intends to question the fundamental design paradigm of current technological artifacts that are commonly characterized by fixed form factors, rigid mechanisms and static enclosures.

Interactive Costumes - How Wearables and E-Textiles can enter Performance Stages (working title)
Michaela Honauer's PhD project investigates wearables and e-textiles in the specific domain of professional stages that have predefined infrastructures and expertise-based hierarchies (e.g. theatre, ballet, opera). Next to the technical challenges for particular use cases, Michaela searches for solutions that help to integrate the production and staging processes of interactive costumes into traditionally grown structures. Her practice-based research is ethnographically motivated and tries to establish working routines and connections to practitioners as well as theatre, opera and ballet houses.

Urban HCI - Understanding Architectural Influences
Patrick Tobias Fischer's PhD work investigated how spatial configurations and architectural elements influence the use of public interfaces. Tobias submitted and defended his PhD at the University of Strathclyde
He continued this work at BUW, and for several years we explored how public interfaces can foster shared encounters, how to evaluate such interfaces, and engaged in a series of design-evaluation experiments.

Interactive Museum Installation – Touchless Interaction via Motion Tracking and Pointing Gestures
3D graphics are common in modern media, while two dimensional input techniques are used for interaction. A variety of devices are used in these contexts to manipulate contents which often are complicated or error prone. But meanwhile, home entertainment-systems can be operated just with hand gestures.
Master student Michael Pannier developed a novel interaction prototype where museum visitors are tracked with a motion sensor (ASUS XtionPRO) and analyzed via the OpenNI framework. A visitor can simply point at the artefacts within a showcase and the software will provide corresponding information on a screen. This provides a low cost and low-maintenance system. Our system also allows the museum staff to set up a new installation, to define and edit the objects of interest within it as well as attach corresponding information, i.e. text and images to be shown on a screen whenever a user points at the artefacts. A particular challenge in this project has been to adapt Kinect-like motion sensing technology to determine pointing targets on a horizontal plane (instead of a vertical screen), to account for angular error, eye-hand visibility mismatch, and pointing inaccuracy.
We collaborated with the local museum of pre- and early history Thuringia (Museum für Ur- und Frühgeschichte Thüringens) to build a system for a showcase, containing the grave of a germanic princess, the 'Prinzessin von Haßleben'. This was installed in July 2014. Michael Pannier furthermore interviewed visitors before installation of the system and after to investigate whether it contributes to making the grave more memorable and increasing people's knowledge about it.
