Touch | Sight| Relocated Self

By deliberately scrambling a person's visual and tactile senses, it is possible for scientists to give them an out-of-body experience.

Most popular of this type of perceptual illusion is the "Rubber Hand Illusion."



New Scientist cites the next demonstration, also performed by UCL's Henrik Ehrsson. Cameras and projections are set up to confuse subjects into experiencing that they are standing somewhere else in the room, reinforcing the idea that peoples' perception of 'self' is tightly bound to how information is processed by the senses.





In these experiments, the sense of touch is synchronized with visual movement. These perceptions are put in conflict with where the synchronization is happening. The brain defaults to vision, which is the most informationally rich sensory modality. As the self is no longer 'within its borders', subjects feel like they're having an out-of-body experience.

Here's a DIY version, brought to you from the guys at Mind Hacks:

"Sit at a table with a friend at your side. Put one hand on your knee, out of sight under the table. Your friend’s job is to tap, touch, and stoke your hidden hand and—with identical movements using her other hand—to tap the top of the table directly above. Do this for a couple of minutes. It helps if you concentrate on the table where your friend is touching, and it's important you don't get hints of how your friend is touching your hidden hand. The more irregular the pattern and the better synchronized the movements on your hand and on the table, the greater the chance this will work for you. About 50% of people begin to feel as if the tapping sensation is arising from the table, where they can see the tapping happening before their very eyes. If you're lucky, the simultaneous touching and visual input have led the table to be incorporated into your body image."

Beyond the practical applications of creating more realistic avatars in virtual reality games, and for doctors' performing remote surgery, these experiments explore the question, 'Why do we feel we own our body?' They indicates that "self" is closely tied to a "within-body" position, which is dependent on information from the senses. Swiss researcher Olaf Blanke concludes, "We look at 'self' with regard to spatial characteristics, and maybe they form the basis upon which self-consciousness has evolved."

Evolving Perception: Tele-Synesthesia and Touch Technology

How are human beings adapting to increasingly virtual environments? Belgian artist and founder of the Belgian Synesthesia Association, Dr Hugo Heyrman, has devoted 40 years to studying and experimenting with perception. His terms 'tele-senses' and 'tele-synesthesia' describe how our senses are merging with and enhanced by interactive technology.

In synesthesia, neurological cross-wiring causes senses to mingle, often with exotic effect. However, we also know that one sense links to other senses by association. In cybermedia, and touch-technology in particular, the boundaries between the internal and external, between the what is here and what is there, become confused. Our senses become 'tele-senses' - enhanced and extended in cyberspace ('tele' means 'far' in Greek). As interactive multimedia and electronic networks create uncharted possibilities of interconnection, we are enabled to expand the reach of our sensorial perception.

'Tele-synesthesia' is the synesthetic principle that is expanded and extended by means of new media: the traveling senses. It is defined as virtual interactions between the tele-senses, developed by means of new technological means in order to overcome the constraints of the human senses.

This is fast becoming reality, and in some cases, aesthetically and conceptually beautiful. Jeff Han of Perceptive Pixel has developed a highly sophisticated, interactive multi-touch technology with multiple user capacity. Each pixel is a touch sensor, providing an infinite number of points that can be captured and manipulated by the user.




The user (or users) simultaneously employs fingers, hands and arms on large-scale screens, collaborating parts of the brain used for interaction with physical objects.

"By synchronising images, sound, movement and haptic experiences, electronic media are able to bring about the intermingling and fusion of one medium into another, resulting in making colours audible, visualising sound and making words palpable... Future libraries will become brain banks instead of book banks, synesthetic archives: an interactive multimedia integration of the visual, the kinetic, the haptic, the sonic, and the telematic."

In terms of adapting to virtual environments & multi-sensory learning, Heyrman concludes that synesthetes, 'Homo Futuris', have a head start on the rest of us: "because with the futuristic, telematic extension of the human senses, everything will become more and more synesthetic."

Customizing Sensory Reality

At October's Simplicity Event, Philips demonstrated its concept Active Glass Dynamic Daylight Window, in the context of a simulated hotel room. This energy-efficient digital lifestyle product allows for guests to use sweeping intuitive gestures to create a personalized sensory environment.

"I like to think of Philips' Dynamic Daylight Window as a practical representation of a much different
future then we might be expecting. Where we live in increasingly
beautiful and interesting environments that keep us fully distracted
from reality. Much more practical then virtual reality. The over
whelming of the senses to create fully synthetic realities is totally
impractical for the near future, but customizing reality to overwhelm
the senses, perfect."

Molecular Cuisine - Alchemy of the Senses

When Oliver Hess of Silverlake's Materials & Applications described bacon lard ice cream as incredible, I was dubious. Of course, like so many things in life, it's about the context.

Molecular cuisine is the end product of molecular gastronomy. Since the 80s, chefs & scientists have been collaborating to experiment with breaking foods down into their most basic components – molecules – seeking scientific explanations to age-old culinary mysteries -- how do our brains interpret signals from the five senses to tell us the “flavor” of food; why is that some foods combine well, while others don’t -- and applying that knowledge to creating new tastes and textures.

Molecular gastronomy is intricately tied to how the human body interprets sensory input. Try chef and researcher Paul Barham's ice cream experiment: Most of us find that a spoonful of ice cream tastes good. Now, close your eyes eating the same ice cream while stroking a piece of velvet, and you'll find that it tastes much creamier. Repeat the same experiment with sandpaper & the ice cream's texture will be grittier.

A watershed moment for molecular cuisine came in 1999, when Heston Blumenthal, chef at the Fat Duck restaurant at Bray-on-Thames in England, shocked the dining world with his fusion of white chocolate and caviar, a combination whose success was explained by the surprisingly similar chemical compositions of the two foods.

Restaurants in New York, Toronto and Tokyo are popularizing the cuisine. Most famous is Ferran Adrià's El Bulli in Barcelona. In the unlikely event of getting a table, look forward to sampling cocoa butter with crispy ears of rabbit; Kellogg’s paella, which consists of Rice Krispies, shrimp heads and vanilla-flavored mashed potatoes; white garlic and almond sorbet; and tobacco-flavored blackberry crushed ice. And for that added dimension, don't forget your fabric swatches.

Killer Threads - Clothing That Harms

Having recently been hospitalized due to an unfortunate incident with a waspie, my thoughts turned to harmful clothing.

Most bewitching were Gordon Savicic's 'Constraint City - The Pain of Everyday Life' and Stahl Stenslie's 'Walker'. Stahl references suicide bombers and a culture in which death is aestheticized while Savicic focuses on (painfully) mapping digital technology's new arenas and interactive spaces on the body. Both projects fetishistically engage and update the tropes of clothing as shelter for the body and of corsetry immobilizing the wearer.

The Walker, a "suicide corset", is a corset placed around the waist that tightens itself a little bit for every step you take - until it is so tight that the wearer suffocates.

'Constraint City' is an urban project, in which a subject dons a corset equipped with servo motors. As the wearer walks about, the corset picks up digital signals in the environment, which reveal their strength by proportionally tightening in the chest of the wearer. Wireless networks spread all over the urban territory are then mapped onto the wearer's own body.


Clothing typically functions as protection for the wearer, and influences how the wearer experiences movement and expresses identity in her personal, social and political environments. These themes have been explored in Comme des Garcons' "Body Meets Dress" at LA MOCA's 2006 'Skin + Bones: Parallel Practices in Fashion and Architecture' and Mauro Taliani's titanium weave men's shirt "Oricalco" at New York Cooper Hewitt's 2002 Skin: Surface, Substance and Design.

With the advent of feminism the constricting buckles and laces of corsetry came to be vilified. Corsets were accused of sexually objectifying the female wearer and rendering her immobile, thus restricting her from the public spheres of politics, religion and business.

Hearing Colors, Tasting Shapes

Synesthesia is a perceptual phenomenon whereby otherwise normal people have 'tangled' senses. The real information gathered by one sense (e.g. sight) is accompanied by a perception in another sense (e.g. touch or sound).

Imagine that every time you saw the number 4, it would be eggshell blue; or every time you heard an F tone you saw a crisp purple arc half a foot in front of you.

Synesthetic perception can occur between any 2 senses. Probably the most common type of synesthesia is grapheme—color (chromatographemic) synesthesia. For the life of the synesthete, letters and numbers are tinged with a particular shade or color. Attending a cocktail party a few years ago, I was chatting about the subject when a handsome stranger suddenly blurted: ”4 is Green! Lettuce is 4!” In his 40s, this eavesdropping attorney had never known there was a name for this peculiarity in his perception. Like most synesthetes, he assumed everyone saw the way he did until an experience at school had him realize he was ‘different’, & he had never mentioned it to anyone until the day we spoke. He later discovered that his father also saw certain letters and numbers shaded. Research does indicate that synesthesia is to some extent hereditary.

Synesthesia usually doesn’t interfere with day to day life. There are 8 times as many synesthetes working in the creative professions – artists, poets, writers, musicians – than in the general population.

Many synesthetes find that having linked senses assists them in tasks of memorization. Musician Noriko Nagata who sees colors in sounds (chromestesia – colored-hearing synesthesia) reports, “As I was receiving professional education in music (I also have a sense of perfect pitch), the resonance of a sound and the image of a color have always been deeply connected. When it came to composing music, I would think, "I will make blue colored music", or think, "What were these codes I remembered in pink and beige?" during a test on guessing the right code names of tension codes. It has been my habit since I was small to feel colors and memorize things in colors using this way.”

Examples of some more elaborate forms of synesthesia follow:

Some synesthetes taste shapes: ergo the statement, ‘There aren’t enough points in the chicken.’ The taste of roast chicken made this synesthete feel a round shape in his hands, as if he were rubbing a bowling ball instead of feeling the prickly shape he expected. (Cytowic, “The Man who Tasted Shapes”, MIT Press p.11)

Others upon hearing a sound see light, color and identifiable images. ‘Presented with a tone pitched @ 250Hz amplitude 64db, S saw a velvet cord with fibres jutting out on all sides. The cord was tinged with a delicate, pleasant pink-orange hue… Presented with a tone pitched @ 3000Hz amplitude 113db, he saw a whisk broom that was of a fiery color, while the rod attached to the whisks seemed to be scattering off into fiery points. The experiments were repeated during several days and invariably the same stimuli produced identical experiences.” (Baron-Cohen & Harrison, "Synaesthesia: Classic and Contemporary Readings", Blackwell Publishers, Cambridge, MA, p.102)

MIT's 'The Synesthetic Experience' has a couple of on-line demos simulating synesthetic experience, and accounts of first-hand experiences of synesthesia.
