“…One aspect that could be worth further investigation is the illumination of the physicalization through the tabletop. By using laser engravings inside a transparent glass object, e.g., with different densities, it could be possible to highlight specific aspects inside the physicalization on demand [Büschel et al, 2014]. We had the impression that the physicalization is degraded to a simple tangible once it is placed on the tabletop as its large digital screen attracts all the attention.…”

“…As we used transparent acrylic glass for our physicalizations, we were inspired by work that used tangibles entirely made of transparent or translucent materials. Such tangibles allow displaying content directly below them and enable dynamic illumination as well as glowing effects [Büschel et al, 2014]. The tracking of tangibles can be realized by using transparent markers [Frisch et al, 2013].…”

“…The tracking of tangibles can be realized by using transparent markers [Frisch et al, 2013]. Furthermore, transparent objects also facilitate direct touch interaction with the content below [Büschel et al, 2014] and even the acrylic carving could be used as an interactive surface [Mikubo et al, 2013].…”

The goal of an external representation of abstract data is to provide insights and convey information about the structure of the underlying data, therefore helping people execute tasks and solve problems more effectively. Apart from the popular and well-studied digital visualization of abstract data there are other scarcely studied perceptual channels to represent data such as taste, sound or haptic. My thesis focuses on the latter and explores in which ways human knowledge and ability to sense and interact with the physical non-digital world can be used to enhance the way in which people analyze and explore abstract data. Emerging technological progress in digital fabrication allow an easy, fast and inexpensive production of physical objects. Machines such as laser cutters and 3D printers enable an accurate fabrication of physical visualizations with different form factors as well as materials. This creates, for the first time, the opportunity to study the potential of physical visualizations in a broad range.The thesis starts with the description of six prototypes of physical visualizations from static examples to digitally augmented variations to interactive artifacts. Based on these explorations, three promising areas of potential for physical visualizations were identified and investigated in more detail: perception & memorability, communication & collaboration, and motivation & self-reflection.The results of two studies in the area of information recall showed that participants who used a physical bar chart retained more information compared to the digital counterpart. Particularly facts about maximum and minimum values were be remembered more efficiently, when they were perceived from a physical visualization.Two explorative studies dealt with the potential of physical visualizations regarding communication and collaboration. The observations revealed the importance on the design and aesthetic of physical visualizations and indicated a great potential for their utilization by audiences with less interest in technology. The results also exposed the current limitations of physical visualizations, especially in contrast to their well-researched digital counterparts.In the area of motivation we present the design and evaluation of the Activity Sculptures project. We conducted a field study, in which we investigated physical visualizations of personal running activity. It was discovered that these sculptures generated curiosity and experimentation regarding the personal running behavior as well as evoked social dynamics such as discussions and competition.Based on the findings of the aforementioned studies this thesis concludes with two theoretical contributions on the design and potential of physical visualizations. On the one hand, it proposes a conceptual framework for material representations of personal data by describing a production and consumption lens. The goal is to encourage artists and designers working in the field of personal informatics to harness the interactive capabilities af...

“…Distributed as a library, it enables the development of applications that need to display contextual information around or below the token. Examples include information filtering using tangibles as see-through tools [6], and games ( Figure 6-(c) demonstrates launching missiles from a tangible spaceship). TouchTokenTracker's recognition algorithm relies on the three points provided in each token template, as the original TouchToken recognizer [19] did.…”

TouchTokens were introduced recently as a means to design lowcost tangible interfaces. The technique consists in recognizing multitouch patterns associated with specific tokens, and works on any touch-sensitive surface, with passive tokens that can be made out of any material. TouchTokens have so far been limited to a few basic geometrical shapes only, which puts a significant practical limit to how tailored token sets can be. In this article, we introduce TouchTokenBuilder and TouchTokenTracker that, taken together, aim at facilitating the development of tailor-made tangible interfaces. TouchTokenBuilder is an application that assists interface designers in creating token sets using a simple direct-manipulation interface. TouchTokenTracker is a library that enables tracking the tokens' full geometry. We report on experiments with those tools, showing the strengths and limitations of tangible interfaces with passive tokens.

“…One TOUCHTOKEN, with matching shape and color, is associated with each category and can be used to adjust the visual representation of the corresponding data points in the scatterplot: changing their size by rotating the token, and their opacity by sliding it. TOUCHTOKENS can be transparent, in which case they will typically be used as physical see-through tools [10,15], altering the content that falls below the token (e.g., filtering) or changing its visual attributes (e.g., rendering). For instance, we have developed a simple mapping application in which tokens are associated with different layers.…”
