Visual Computing Forum


The Visual Computing Forum, or VCF, is a series of seminars organized by the visualization group with selected talks from the fields of visualization, image processing, computer graphics, and so on. The individual seminars are arranged approximately once a month, on Fridays from 11am to 12am, and they will be interleaved with the MedViz seminars. They will be held either at the Høyteknologisenteret or at the VilVite Science Center.
If you wish to be informed about upcomming VCF events, please write an e-mail to "vcf.bergen@gmail.com", "Helwig.Hauser@UIB.no" or "Sergej.Stoppel@UIB.no".

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.
