Technoetic Telos

May 11th, 2012 by Tegan

Tegan Bristow lecturer and coordinator of the Interactive Digital Media postgraduate stream in the Digital Arts Division recently attended the Technoetic Telos: Art, Myth and Media conference in Kefalonia, Greece. It was a fascinating conference addressing technology, arts and consciousness in contemporary society. Topics ranged from the Philosophy of Science to Afro-futurism. If you are interested in the topics, the program for the conference can be found here: and papers will be published in the next Telematic Arts Journal for 2012.

 

The conference session ran parallel to a research update for Bristow with the Planetary Collegium with whom Bristow is taking her PhD, through CAiiA at Plymouth University, UK. The program is an international PhD with nodes in Zurich, Sao Paulo, Milan and now an Ionian Node that was inaugurated at this conference. The conference’s act as an opportunity for all the nodes to share research and practice with the many international delegates in the field of technology arts that attend the conferences.

 

Bristow’s PhD research concerns arts practice with Digital Technology in South and East Africa. Her paper at the Technoetic Telos was on Afro-futurism as an African Diaspora aesthetic movement in the 70’s and 90’s and how it relates Digital Arts practice in South Africa.

Computer Vision Experiments

May 11th, 2012 by Tegan

Computer Vision is an interesting and complex digital sensing mechanism, which uses the web camera as a primary sensing device. With something as simple as a digital camera and the right software development, it is possible to do color tracking, motion detection and body detection. As part of the post graduate course work program in interactive media, students will do a Computer Vision project in which they are required to quickly develop an interactive video artwork that uses computer vision as it’s primary interaction interface.

 

Here are just two projects caught on camera in the 2012 Lab. Tina Cladis’ “Vishnu” that uses color placement to create perfect musical harmonies. The program would generate sound based on the placement of large blocks of color. It acted as a sort of multi-player game in which the right colors needed to be position in the right locations for harmonious tones to be generated.

 

This is Felix Urban’s “Wipe Your Soundscape” which is primarily concerned with noise pollution in urban environments.  By wiping clean the “surface” of the sound the participants will “clean up” the sound, taking out all the excess noise of cars, airplanes and noisy chatter, leaving the quiet serene sounds of nature.

 

The development of these engagements followed a intensive workshop on lighting with artist Vaughn Sadie and a computer vision workshop with Tegan Bristow.

GravitySpace – Digital Soiree

February 16th, 2012 by Tegan

Visiting Speaker Jossekin Beilharz
Object identification and Pose Recognition on a Pressure-Sensitive Multi-Touch Floor.

Date: Tuesday 21st Feburary 2012
Time: 13:15 – 14:00
Place: Digital Arts Convent Building, opposite Wits School of the Arts

” We propose a new approach to tracking users, objects, and activities in a smart room. Unlike traditional approaches that point cameras into the 3D volume of a room, we provide all horizontal surfaces with touch sensitivity, including chairs, tables, and the floor. Gravity pushes people and objects against these surfaces, causing them to leave imprints, i.e., pressure distributions across the surface. We demonstrate how to decompose these imprints into the object and pose that caused them. The particular “perspective” reduces occlusion issues faced by regular and depth cameras. It also limits the freedom of objects from rotation and translation in 3D to rotation and translation on a plane, which allows us to recognize objects using simpler and potentially more reliable matching algorithms. We present our 8m2  floor installation, a set of active and a set of passive touch-sensitive furniture, as well as the algorithms we created for recognizing objects and poses.”

About Jossekin Beilharz:
Currently working at SAP Research, Pretoria and a member of House4Hack, Centurion. A masters student of IT-Systems Engineering at Hasso-Platter-Institute at the University of Potsdam. He worked on gravitySpace with Prof. Patrick Baudisch, chair of the Human Computer Interaction Lab at HPI in 2010-2011 and initiated a Random Hacks of Kindness event in Pretoria.

Encircling the Land

December 5th, 2011 by christo

Encircling the land -  photographic exhibition at Substation Gallery

"Encircling the Land"  is a photographic investigation of the Tswaing meteorite impact site by Stanley Sher.

Imagery from space and research on craters like Vredefort and Tswaing have established that meteorite impacts were surprisingly frequent in earth’s history, having both cataclysmic as well as life-enabling consequences for our planet. Most of these effects are hidden from us by time and geological processes which have further altered the landscape, covering the past. The Tswaing impact crater being relatively well preserved, provides visible form to these embedded events from our deep past.
 
This exhibition of 360° panoramic photographs emerges out of a series of encounters over a period of 6 months in the Tswaing meteorite impact crater. Time of a different order, is also pivotal in the photographic process, which attempts to assemble fragmented moments within a single image. The inevitable inconsistencies of light and shifting viewpoint over the 360° rotation contribute to the complexity of actually apprehending this landscape. The images retain these disruptive elements, including the digital ‘noise’ which is an artefact of a digitised process.
 
In exploring the hermeneutic question of how to read and apprehend the landscape, the exhibition is the visual component of an investigation which establishes a dialogue, embracing understandings and perceptions from the arts and sciences. The geology and history of the Tswaing crater forms the backdrop to this dialogue which considers traditional and contemporary readings, representations and interactions with landscape.
