The Kiki-Bouba Sensorial Communication Lab

The Kiki-Bouba communication lab was first held during the 'Beyond the body' exhibition an external exhibition to the Venice Biennial 2024


Sensorial Communication Lab May 24, Venice

My work delves into the intricate world of sensorial forms, exploring how we perceive and attempt to express sensory experiences. We often find that our languages, especially in Western contexts, lack the vocabulary to describe sensory impressions such as the hue of a flower or the texture of its petals. This phenomenon, often referred to as the "ineffable" nature of sensory experience, raises intriguing questions: Is our ability to articulate these impressions constrained by the wiring of our brains, or is it shaped by cultural and linguistic factors? (Inspired by Asifa Majid's ongoing research)


In addressing these questions, I developed a visual language for scent in 2020. Going forward I explore both the traditional five senses and the lesser-known hidden senses, such as proprioception and interoception, which inform us about the internal state of our bodies. My research is inspired by ideophones—sound-symbolic words common in many non-Western languages—that serve as sound paintings, providing a non-arbitrary link between sound and meaning. This idea of a non-arbitrary sign led me to develop a systematic method for mapping sensorial impressions using two axes: valence (positive or negative mood) and intensity.


Building on this, I created a visual system that uses waveforms as a universal language for expressing sensorial experiences. This system draws on the psychological phenomenon where certain shapes and sounds, like the "kiki" (sharp, angular) and "buba" (soft, rounded) experiment, consistently evoke specific associations. By integrating these principles, I have designed a font that encapsulates the essence of sensory experiences, enabling a new way to communicate these impressions.


The Kiki-Bouba communication lab was first held during the 'Beyond the body' exhibition in Venice in 2024, where people were invited to put on a wearable suit that alters the wearer's sensory perceptions and uses the "Kiki-Buba" communication method to express these altered states. The wearables are developed based on UP - User presence, a UX derivative methodology I developed during my MA studies, designed to incorporate a sense of presence into reality-shifting devices.



The Kiki-Bouba Sensorial Font


Try to describe the nuances of a roses' scent, the actual tactile experience of its petals, and its exact hue. You can't put it into precise words. Enafable senses are at the focal point of the KikiBouba sensorial font, a new way to trap sensorial impressions in writing.


What senses are easier to describe? It depends on who you ask. Western cognitive scientists would argue that touch and scent are less accessible to expression. Majid & Levinson, at a conference in 2011, posed the question of whether this approach is culture-dependent or brain-wired. At that conference, many who participated in 'The Language of perception across cultures' project shared their findings.


Mark Dingemanse shared his psycholinguistic point of view. He described a Ganayc village where an encounter with a fruit merchant is ongoing. Ideophones enrich the dialogue between the participants who speak Silu. They would say 'ìgbèdi sinisinisinisini' to express how smooth the Qassava is. One would worry that the unripe bananas would make his teeth sticky. He would say, 'kànya amε tìtìrìtììì' . One of the advisors shared that Ideophones are like pepper. Without them, speech is buàà [tasteless]


Ideophones are sound pictures, as Wilhelm Wundt coined the term Lautbilder in 1900. These words have distinct grammatical characteristics. They are rare in English, but they can be found in many other languages, such as Japan, Korea, and Africa.


Ideophones and onomatopoeia, a sub-use case of ideophones, are sound utterings that unite meaning and sound. A known experiment shows two closed shapes, one that is pointy and one that is round. When asked, most people would match the sound kiki to the pointy shape and the sound Bouba to the rounded shape.


I'm fascinated by the infallible state, where we cannot express, describe, and share what we sense or feel because of the lack of proper signs. Formulating the kiki-Bouba sensorial font is another step toward a visual language for scent.


I'm inspired by the ideophones' ability to spice communication with an utterance that, for a speaker of an ideophone-rich language like Korean or Japanese, feels like a heightened experience, one that enables him or her to feel out there, with the speaker feeling closer to his or her experience.


doki doki (ドキドキ) heart-pounding is used to express an agitated state of mind. This means that ideophones can express complex emotional states, not just sensory impressions.


To formulate a visual symbol system that enables us to express sensorial impressions in writing, I need to attain two things -

To show how one can use a limited number of symbols to express different sensory stimulation.

To discover a systemized principle to map sensorial impressions

To formulate a non-arbitrary sign.


I detail my quest to fulfill these conditions here.

Use shift+` shift+1 shift+2 shift+3 shift+4 shift+5 shift+6 shift+7 shift+8 shift+9 shift+0 shift+-


and combine them to express where you feel the sensorial impression in your body, how intense it is, and how pleasant/unpleasant it is.


I'd love to know what you've discovered.
