Intel Perceptual Computing Challenge

Two of our apps were choosen as a prize winner in the Intel Perceptual Computing Challenge 2013. Our CubeFlow app won a 2nd prize in the category open innovation. CubeFlow allows the user to create volumetric shapes from finger movements.

2nd Prize Winner: CubeFlow at Intel Perceptual Computing Challenge 2013

Our second submission “CubeSculpt” won a “Pioneer Award” in the category productivity. CubeSculpt was an app prototype to use hand gestures to freeform sculpt 3D models.

Applications of Social Network Analysis

We attended the ASNA conference 2012 and presented a paper about “Semantic Network Analysis as a Method for Visual Text Analytics” as a part of our research work. This paper can be read as a follow up on the EuroVA paper as it demonstrates the proposed method for visual text analysis in an exemplary application. The paper will be published in 2013.

GPUerror – visual computing arts experiment

By serendipity this visual computing experiment led to a visualization of colorful structures that evolve from the parallel propagation of errors on a graphics processing unit (GPU). We wanted to transfer color values in subsequent volume slices using an OpenCL kernel. Due to concurrent memory access this transfer operation was erroneous and produced interesting visual patterns in a point-based visualization. Meanwhile we fixed this “error” with another kernel but we wanted to share the initial results as a piece of visual computing art. The visual patterns reveal the structure of block-wise kernel execution on the GPU. Further information on this experiment and code snippets (PDF).

Visual Text Analytics using Semantic Networks and Interactive 3D Visualization

Short paper presentation at EuroVA 2012. Abstract:

Semantic Network Analysis using 3D Graph Visualization

Facing the growth of textual information, the analysis of unstructured text data remains a challenge for visual analytics. Most text visualizations are based on models that use word frequencies for text vectorization and representation. As semantics reveal from word relations, we propose an integrated visual text analytics approach that utilizes semantic networks in an interactive 3D workspace for exploration and analysis. Semantic networks act as an intermediary structure for data modeling and interactive visualization to support the visual analytics process. Focussing on the integration of text analysis and visualization, this paper describes our system design and its preliminary implementation. Discussing typical usage scenarios and a practical field-test, we present a strategy for text exploration and analysis to illustrate the usage of our system in an exemplary use case.

Guest lecture: digital publishing for mobile devices

This lecture discussed different possibilites for digital publishing on mobile devices. In respect to the variety of devices, platforms, operating systems, vendors and technologies a common approach seems difficult. Standardized web technology proposes a good approach to cross-platform concepts and data formats. The blend of web-apps with rich internet applications (RIA) would confirm those trends.
