Mirror Gaze Experiment @MSP
I have been working with Manchester Science Partnerships to develop a range of workshops for their customers, the resident companies that use the park. The first session was the 'mirror gaze experiment'. During the mirror gaze experiment [MGE] participants are asked to stare at their own reflection in a mirror in a nearly dark room. An outline of the head is visible as a faint silhouette. In this state of partial sensory deprivation, the brain struggles to make sense of the information it sees. Forms and shapes begin to emerge as if from nowhere. For many observers, these develop into vivid visual hallucinations “monsters, archetypical faces, faces of relatives, and animals” (Caputo, 2012; Bortolomasi et al., 2014). This
Emergent Strange faces

This used the program Isadora to detect movement using a ‘difference filter’ and building up an image using 'shimmer' and 'motion blur' filters with a long decay rate. An image builds up based on the collective movements of all 3 participants. A collective strange face. Emergent strange face from Proximity project Emergent strange face from Proximity project

Mirror gaze experiment
The mirror gaze experiment requires the participant to sit in a near dark room and to stare at their own reflection for a set amount of time while listing to white noise. After only a short amount of time most people experience powerful illusions of facial distortion, grossly exaggerated features, faces of animals, the face of a lion or Darth Vader for example. These emerge as if from nowhere, disappearing at the slightest movement or eye blink, before manifesting new forms. These flowing cascades of illusory effects can elicit powerful emotional responses. In my own research, the mirror gaze experiment has resulted in significant illusory experiences across the full range of participants. I documented the way in which the illusory experience
Fish-brain-machine / Radiona workshop
After constructing the Fish-brain-machine PCB circuits we spent some time experimenting and describing the hallucinogenic visuals created by the stroboscopic light. The ping pong balls over the eyes diffuse the LED light, making for a more intense effect - and enabling use with eyes open. Here they describe some of the effects including seeing colours and 'a strange experience' of seeing with only one eye - I get this exact same feeling when using it. It is also hard to know if your eyes are open or closed. [See also Re-mapping the senses workshop ] https://www.youtube.com/watch?v=Lwne5xICLkI
Fish-brain-machine
As part of my Enki exhibition at Kapellica Gallery in Ljubljana 2012, I developed a related perceptual illusions and brain hacks workshop with Marc Dusseiller [Hackteria], as part of the gallery’s Biotech program. We came up with the idea to make a special issue circuit for the workshop and we set to work designing a circuit the encapsulated the Enki project in miniature. After a couple late nights, we came up with this super cool PCB design. Marc worked hard to create a fully functional efficient design, which was also aesthetically pleasing. The outline of the fish is also the ground in the circuit. This has to be the most ultra minimal brain-machine available to build. 6 components. We spent further
Strange face illusion with two-way Mirror feedback
“… a quiet room dimly lit by a 25 W incandescent light. The lamp was placed on the floor behind the observer so that it was not visible either directly or in the mirror. A relatively large mirror (0.5 m60.5 m) was placed about 0.4 m in front of the observer. The luminance of the reflected face image within the mirror was about 0.2 cd mÿ2 and this level allowed detailed perception of fine face traits but attenuated colour perception…The task of the observer was to gaze at his/her reflected face within the mirror. Usually, after less than a minute, the observer began to perceive the strange-face illusion…” Giovanni B Caputo, Perception, 2010, volume 39, pages 1007 – 1008 2010
Blind drawing of hand
Blind drawing of hand starting from the left and using a continuous line, before and after experiments. Could this exercise be used as a measure of "proprioceptive drift" before and after 'Rubber hand illusion' type experiments? I will be exploring this idea soon with the research group at BEAM lab...
James Turrel – Light Reignfall
[vimeo 75419053 w=640 h=360] James Turrell's Light Reignfall @LACMA - Andrew van Baal James Turrell's Light Reignfall Light Reignfall is a work from his series of perceptual cells, inside the participant is exposed to a uniform homogenous field of modulated light. A combination of sensory overstimulation, yet deprived of recognisable forms or space, hallucinatory effects are experienced. “Assisted by an attendant, an individual viewer enters a spherical chamber on a sliding bed. A program of saturated light (operated by a technician) surrounds the viewer for twelve minutes, allowing the visitor to experience the intense, multi-dimensional power of light and the complex seeing instrument of the human eye.” "James Turrell (b. 1943, Los Angeles), a key artist in the Southern California Light and Space movement
