Rhizome.org: Black Hole of Vision: On Rune Peitersen’s Saccadic Sightings

By Vesna Madzoski on Wednesday, September 8th, 2010 at 12:00 pm.


If our eyes were to be turned into a camera, it would be a rather poor device. More precisely, it would not resemble a single-frame snapshot camera, but a video stream of a mostly blurred visual field with only spots of clarity. Our eyes move rapidly and continuously update the image in the brain, and it has been concluded that the brain, resembling a high-tech processor, cleans up the received input. Paradoxically, one of the functions of photography is to remind us of the impossibility of our eyes to perceive reality as a still image – as the saccadic scanning of our eyes show, there is nothing fixed or stable in nature. Matter is always in flux.

In her weekly column in the Dutch NRC Handelsblad, Maria Barnas contemplates the difficulties of grasping Einstein’s theory of relativity and how Andre Klukhuhn’s lecture at the minisymposium made her come closer to an understanding of the fourth dimension.

Saccadic Sightings: Einstein&Bohr, at Ellen de Bruijne Projects, July 3rd to August 28th

THE VIDEOS FROM THE MINI SYMPOSIUM JULY 8th ARE NOW ONLINE.


 

 

In Dolores Rune Peitersen will be showing the most recent installment, Einstein & Bohr, from his ongoing project Saccadic Sightings from July 3rd to August 28th.

Initiated in 2008, Saccadic Sightings began as a study of visual perception. Using a Mobile Eye, a scientific eye tracking device, Peitersen was able to film his field of view while simultaneously capturing the exploratory movements of his eye. He was interested in the ‘raw’ visual input captured by the retina before it was interpreted and processed into experience by the brain. Underlying this project were questions raised by quantum mechanics concerning e.g. the Uncertainty Principle and whether or not it is possible to speak of a world separate from our observation of it.

During his research Peitersen started looking into the way in which we construct our reality. Besides the physiological and psychological aspects of perception, scientific paradigms determine our view of the world. Peitersen became intrigued by how outdated but popular paradigms have developed into inflexible dogmas. The materialistic dualism of Rene Descartes, which presupposes a strict division of mind and matter, is such a dogma, which although discredited decennia ago by quantum physics, by thinkers such as Einstein and Bohr and more recently by neurological research, still remains the most commonly accepted and widely held world view. This raises the questions of why such a world view persists and what can be done to substitute it with a more adequate construction. Furthermore, Peitersen became convinced that it is art which shapes our understanding of reality. By formulating questions about perception, by visualizing conceptual constructions and making these constructions manifest in the world, art plays a much more fundamental part in the construction of our collective reality than we usually realize.

These are the considerations underlying the most recent work. In one image we see the track travelled by the searching eye. It is superimposed on a video still of an urban landscape: a snapshot, out of focus but still implying an overview. In the second work, a combination of several images, the overview is abandoned in favor of fragmented visual acuity also referring to the passage of time. Both works are linked to the text Einstein & Bohr.


The issues raised will be the starting point of a public discussion in the gallery on Thursday July 8th in which Robert Zwijnenberg (Prof. Art history, University of Leiden and founding Director of The Arts & Genomics Centre), André Klukhuhn (scientist and philosopher), Saskia Monshouwer (curator and anthropologist), Mariska van den Berg (curator SKOR), Voebe de Gruyter (artist), Huib Haye van der Werf (curator NAi), Anne Kienhuis (postdoc researcher at RIVM), Tamuna Chabashvili and Adi Hollander (artists PSWAR.org), Laura Schuster (phd student UvA, Imagined Futures research group) and others will participate.

Studio views

At the moment I’m trying to find a good way to present the information from the tracking. In the images below the  input from the eyetracking recordings is condensed to give a visual approximation of the foveal input. This is the next step in the ‘Observer Effect’-series. I wasn’t satisfied with the static and highly abstract imagery of the first works of that series. I decided to break up the images into several smaller segments. Each individual photo in the works, is a 4 sec. (100 frames – photoshop layers) digital compilation of foveal input. Each row contains 10 photos (40 sec.). This enables the viewer to actually get an idea of what he is looking at, by ‘gathering’ infromation from the different images in the work.

The Retinal Image is Unstable

“The Retinal Image is Unstable

Matters are made worse by the fact that the eyes move almost continuously. Several times a second they jitter and bounce; they also make saccades and micro-saccades-that is, sharp, ballistic movements. As a result, the projection of an object you perceive to be still in facts jumps around on your eyeball, and when you track a moving object, its image stays still on your retina while that of the stationary background races across your eyes. Again, in order to explain how we manage to experience a stable visual world, we need to suppose, it seems, that the ability is achieved at some later stage in the processing of the original retinal information.”

Alva Noë, p. 133-134, ‘Out of our heads’, Hill and Wang 2009

In his new book, Out of our heads, Alva Noë advocates a radical change in how we think of the consciousness and how to resolve the Cartesian dualistic dilemma. The above quote refers to the problems which arise when trying to explain the visual world as something separate from the perception of it. It also very neatly sums up the technical starting point for Saccadic Sightings.

Long Overdue Update

The last half year I have been busy getting deeper into the material, the MobileEye footage. As I become more familiar with the material, I notice I’m increasingly liberated from considerations of a ‘scientific’ nature and can concentrate more freely on developing a visual language, which takes its outset in the original ideas and footage, but is also more ‘open’. I have been motion tracking a lot of the eyemovements, which allows me to use the data in other applications as well. This is a time consuming process, but one, that in the end will give me a great amount of freedom and control over the imagery and allow for much more visual experiments.

The first examples hereof are to be shown at GIST Gallery Amsterdam, Oct. 16th – Nov. 21st 2009 (see News). The show, Divided Landscape, is curated by Carolien Stikker, who has invited artists who work with vision and perception, to show works alongside her. There will be an essay on the subject by Mariska van den Berg.

Due to the method I have developed to create the images (multiple screenshots combined in Photoshop), they are almost impossible to scale. The originals vary in size from 150/100 cm to 18/13 cm. The images below don’t do justice to the detail, but may give a general impression.

New movies

For some time now, I have been in the process of editing the material I shot with the MobileEye. So far I have finished one movie, Encounters, which was shown at Discovery08. The movie deals predominantly with the mental associations involved in visual experiences. I used the interlaced footage as base for most of the imagery. Basically it is a mix of 3-5 different sequences (narratives) interwoven and repeated several times with slight variations. It doesn’t have a beginning or ending and is meant to loop endlessly (the video runs for appr. 10 min.). Although it might be able to stand alone, the final result will be the installation of several videos in a manner I still have to decide on. The installation should work by allowing the viewer to see one or more of the videos at any given time, and by creating associations and links across the videos, not just in the videos.

At the moment I’m working on the second video (almost done!), working title Ophelia.

Below are two links, one is an excerpt from Encounters, the other is an excerpt from a MobileEye recording with tracking.

CHArt Conference

The CHArt Conference in London was very good. I don’t consider myself an academic, but it is interesting to get a peak inside the academic world on occassion. A lot of interesting papers were presented, and my own presentation on the project was well received. I hope to be able to provide a video of it soon. The paper I presented can be downloaded below.
