Title: Gameworld Interfaces
Speaker: Kristine Jørgensen
Place: Thormøhlens gate 51 (VilVite), Konferanserom A
Time: Friday November 24th, 2017, from 10:15am to 11:00am
Abstract:
Designing so-called “invisible” interfaces that are integrated into the gameworld is a trend in modern
game user interface design, and debates about the superiority of such interfaces frequently appear in
game developer discourse. At the same time certain genres do not seem to pay this trend any attention
and continue to use a lot of screen space on heavy overlays. While proponents of “invisible” interfaces
believe that this approach provides the greatest sense of involvement for the player because the fiction
appears unmediated, defenders of the second approach believe that clear information is necessary for
overview and control and therefore a support for involvement.
In this presentation I will discuss the main points in my monograph Gameworld Interfaces (MIT Press 2013).
At the core of my argument is the idea that regardless of how the user interface is presented in games,
it is a necessity to be able to present gameplay relevant system information to the player. For this
reason, the conflict is not about whether or not to have an interface at all, but how to present system
information in a way that is clear and communicative at the same time as it is elegant and takes up as
little screen space as possible considering the information needs of the specific game.

Title: Challenges of Visualization
Speaker: Helwig Hauser
Place: Thormøhlens gate 51 (VilVite), Konferanserom A
Time: Friday October 20th, 2017, from 10:15am to 11:00am
Abstract:
Since 2007, Helwig Hauser is professor at the University of Bergen, Norway, where he is leading the research group on visualization.
During the first four years, the group grew to a size of 15 researchers, working on projects in medical visualization, the visualization
of geological data and models, flow visualization, the visualization of biological data, marine data visualization, and others. Since
then, the group is continuously contributing to the field.
Helwig Hauser's interests are diverse in visualization and related fields, including interactive visual analysis,
illustrative visualization, and the combination of scientific and information visualization, as well as many other related topics.
Helwig Hauser is also particularly interested in the application of visualization to the fields of medicine, geoscience, climatology, biology, engineering, and others.

Title: 3D Imaging of Museum Collections
Speaker: Hanneke Meijer
Place: Thormøhlens gate 51 (VilVite), Konferanserom B
Time: Friday September 15th, 2017, from 10:15am to 11:00am
Abstract:
3D imaging techniques can provide a range of exciting opportunities for
museum collections, research, exhibits, education and outreach. In this talk, I
will highlight some of the potential uses of 3D imaging techniques for the
Bergen University Museum. For instance, digital models of specimens can
reduce damage that occurs when delicate or rare specimens are handled by
researchers. Rather than loaning specimens to researchers, (high-res) 3D
models of specimens can easily be shared with researchers worldwide, thereby
facilitating research and reducing the need for travel. Furthermore, with only a
small portion of collections on display in museum exhibits, digitization affords
the opportunity to bring the remainder of the collection into the virtual light
and allows the public to interact with museum collections. Finally, with 3D
printing, educators can integrate 3D technologies into their classrooms.

Title: Data visualization in society: creating meanings and feelings through the visualization of numbers
Speaker: Nils Martin Engebretsen
Place: Lille auditorium (208N2), 2rd floor Høyteknologisenteret
Time: Friday May 5th, 2017, from 10:15am to 11:00am
Abstract:
We witness today an increased use of data visualization (DV) in a number of fields and genres:
in journalism, in education, in commerce and industry etc. DV – in the forms of colorful graphs,
maps and diagrams – are used to inform, convince and tell stories, and they promise to make
both statistical material and unstructured flowing data accessible and intelligible even for
untrained users. New affordances of dynamics and interaction introduced by digital media
technology, make the landscape of DV-design even more rich and complex, and call for new
and updated descriptions, models for learning and investigations concerning semiotic qualities
and social functions.
Martin Engebretsen, professor at UiA and leader of the NFR-funded project INDVIL (Innovative
Data Visualization and Visual-numeric Literacy) will share future plans and preliminary
results from the project (see www.indvil.org) He will focus specifically on the use of DV
on online news sites. The main questions are: What characterizes the use of data
visualizations on major Scandinavian news sites today and how do they create meanings
and feelings?

Title: Abstraction in Non-Photorealistic Rendering and Illustrative Visualizations
Speaker: Tobias Isenberg
Place: Lille auditorium (208N2), 2rd floor Høyteknologisenteret
Time: Friday April 7th, 2017, from 10:15am to 11:00am
Abstract:
Abstraction is a concept that is fundamental in both non-photorealistic rendering (NPR) and (illustrative) visualization.
In NPR, abstraction is introduced by choosing a subset of elements to depict, by simplifying the depicted elements, by
choosing a particular style of depiction, or by even changing the underlying geometric model. Here, abstraction typically
serves an aesthetic goal. In illustrative visualization, abstraction is often used to emphasize important parts and
de-emphasize less important ones. Traditionally, however, most authors argue that by simply using an NPR style or by
using methods from illustrative rendering they automatically abstract---only few approaches actually discuss how the
abstraction is introduced, what types of abstraction exist, and how abstraction can be controlled.
I will discuss three approaches that not only rely on abstraction but also allow users to control it. First, I will
discuss an approach for the abstraction of visualizations of molecular structures in which a continuous abstraction
space between structural abstraction, abstraction through spatial perception, and abstraction by means of "illustrativeness"
is created. Users can navigate this space to adjust visualization to their specific needs. Then I will talk about the
abstraction of brain connectivity though the contraction of fiber tracks based on local similarity. And finally, I will
discuss an example from NPR in which different abstraction strategies are used to affect map data in order to create an
abstract map representation that is guided by each person's individual aesthetics.

Title: Weather and Climate, a Playground for Big Data and Visualisation
Speaker: Thomas Spengler
Place: 302O2, 3rd floor Høyteknologisenteret
Time: Friday March 10th, 2017, from 10:15am to 11:00am
Abstract:
Weather and climate science is among the most demanding in terms of challenges for computation and data.
Terabytes of data are produced every day for operational forecasting, but at the end most people are only
interested in a few symbols on their favourite weather app worth a few kilobytes. I will touch on the
principles of weather forecasting and the computational demands and challenges for data input and transfer.
In particular, I will also focus on current research questions with respect to storm development and
state-of-the-art analysis techniques, including feature detection and data reduction using theoretical
assessments of the flow evolution.
I will also highlight challenges in visualising our conceptual understanding of the workings of
the weather and point to open questions regarding best use of the available data given the current
research questions, also with respect to ensemble prediction. As an outlook, I will also touch on data
availability at our institute for possible collaboration and close with open questions from the atmospheric science side.

Title: Content Delivery for Tomorrow: From Vibrotactile Notifications to Mid-Air Displays
Speaker: Morten Fjeld
Place: 302O2, 3rd floor Høyteknologisenteret
Time: Friday February 10th, 2017, from 10:15am to 11:00am
Abstract:
Vibrotactile notifications can be supportive as our visual attention is often overtaxed,
both in mobile and fixed settings. In the first part of this talk, we investigate how users
perceive spatiotemporal vibrotactile patterns on the arm, palm, thigh, and waist. Results of
the first two experiments indicate that precise recognition of either position or orientation
is difficult across multiple body parts. Nonetheless, users were able to distinguish whether
two vibration pulses were from the same location when played in quick succession. Based on
this finding, we designed eight spatiotemporal vibrotactile patterns and evaluated them in
two additional experiments. In the second part of this talk, we present HaptiColor, an
assistive wristband that encodes discrete color information into spatiotemporal vibrations
to support colorblind users to recognize and compare colors. In the third part of
this talk, we speculate around how advances in display technologies could soon make wearable
mid-air displays—devices that present dynamic images floating in mid-air relative to a mobile user—available.
