1. Seminar on Aesthetics of Electronic Creations Professor: Rejane Cantoni, PhD electronic Brazilian artist Tuesday This seminar took place at the Jaime Hoyos Auditorium of Javeriana University, on Tuesday the 28 th, Wednesday 29 th, and Thursday the 30 th of March, in 2006. As a teacher of the Aesthetics Department, I was invited to introduce the seminar the first day to other teachers and students coming, by presenting a 20 minutes comment on the artist’s work. www.rejanecantoni.com

3. I divided my 20 minutes speech on three parts: I.From Opera to Op-era… Historical background on theater stages and theater machinery that I related to Cantoni’s artwork ‘Op-era’. II. Virtual spaces, virtual beings, virtual life forms? Virtual reality vs. physical ubiquitous computing Comparison on two computing models: the virtual reality one used by Cantoni, and the physical ubiquitous computing one proposed by Mark Weiser. Weiser was critical towards the V.R concept of immersion, and its impact on human beings. I presented my own research on the two models in the courses I work on, ‘Virtual Theater’, and Digital Lifelab. III.Interactive installations as ‘Transforming mirrors’ Cantoni’s installations seen through the concept of ‘Transforming mirrors’ stated by electronic artist David Rockeby
