Taste retargeting selectively changes taste perception using taste modulators, chemicals that temporarily and selectively alter the response of taste receptors to subsequent foods and beverages. As our technique can be delivered as droplets before eating or drinking, taste retargeting is the first interactive method to selectively alter the basic tastes of real foods without obstructing eating or impacting the food's consistency. This technique allows a single food prop to taste like several virtual foods, which we validated in our second study. For example, a pickled blackberry prop can be retargeted to a lemon (decreasing sweetness with lactisole), then a strawberry (transforming sour to sweet with miraculin), and more.UIST'23 paper | Video | Hardware schematics

Low-fidelity prototyping is foundational to HCI. So, how do experts prototype olfactory experiences? We interviewed eight experts and found that they do not because no process supports this. Thus, we engineered Smell & Paste, a low-fidelity prototyping toolkit. Designers assemble olfactory proofs-of-concept by pasting scratch-and-sniff stickers onto a paper tape. Then, they test the interaction by advancing the tape in our 3D-printed (or cardboard) cassette, which releases the smells. Our toolkit uses commodity materials; keeps iterations quick, approachable, and cheap; and circumvents electronics, programming, and chemical handling. The toolkit was approachable to people of any technical background, and novices and experts appropriated and extended it. Novices produced prototypes quickly, and experts were excited about the kit's technical affordances and integrating it into their practice.CHI'23 paper | Video | Kit Files

We propose a new class of haptic devices that provide haptic sensations by delivering liquid-stimulants to the user’s skin; we call this chemical haptics. Upon absorbing these stimulants, receptors in the user’s skin are chemically triggered, rendering distinct haptic sensations. We identified five chemicals that can render lasting haptic sensations: tingling (sanshool), numbing (lidocaine), stinging (cinnamaldehyde), warming (capsaicin), and cooling (menthol). To enable the application of our novel approach in a variety of settings (such as VR), we engineered a self-contained wearable that can be worn anywhere on the user’s skin (e.g., face, arms, legs).UIST'21 paper | Video | Talk | Hardware schematics

We propose a novel type of olfactory device that creates a stereo-smell experience, i.e., directional information about the location of an odor, by rendering the readings of external odor sensors as trigeminal sensations using electrical stimulation of the user’s nasal septum. The key is that the sensations from the trigeminal nerve, which arise from nerve-endings in the nose, are perceptually fused with those of the olfactory bulb (the brain region that senses smells). To realize this, we engineered a self-contained device that users wear across their nasal septum. Our device enables expressive trigeminal sensations and could function as an assistive device for people with anosmia, who are unable to smell.CHI'21 paper | Video | Talk | Hardware schematics

We explore a temperature illusion that uses low-powered electronics and enables the miniaturization of simple warm and cool sensations. Our illusion relies on the properties of certain scents, such as the coolness of mint or hotness of peppers. These odors trigger not only the olfactory bulb, but also the nose’s trigeminal nerve, which has receptors that respond to both temperature and chemicals. To exploit this, we engineered a wearable device that emits up to three custom-made “thermal” scents directly to the user’s nose. Breathing in these scents causes the user to feel warmer or cooler.

We improved the dexterity of the finger flexion produced by interactive devices based on electrical muscle stimulation (EMS). The key to achieve it is that we discovered a new electrode layout in the back of the hand. Instead of the existing EMS electrode placement, which flexes the fingers via the flexor muscles in the forearm, we stimulate the interossei/lumbricals muscles in the palm. Our technique allows EMS to achieve greater dexterity around the metacarpophalangeal joints (MCP), which we demonstrate in a series of applications, such as playing individual piano notes, doing a a two-stroke drum roll or barred guitar frets. These examples were previously impossible with existing EMS electrode layouts.CHI'21 paper | Video | Talk

Existing shape-changing floors are limited by their tabletop scale or the coarse resolution of the terrains they can display due to the limited number of actuators and low vertical resolution. To tackle this, we engineered Elevate, a dynamic and walkable pin-array floor on which users can experience not only large variations in shapes but also the details of the underlying terrain. Our system achieves this by packing 1200 pins arranged on a 1.80 x 0.60m platform, in which each pin can be actuated to one of ten height levels (resolution: 15mm/level). This work was a collaboration and was led by Andrea Bianchi, who runs the MAKinteract group at KAIST.

Panel discussion at ACM CHI 2023 amongst Jofish Kaye, Marianna Obrist, Judith Amores, and I. We responded to the following thought: Scent technology has evolved from its use in 1960s cinema to internet peripherals in the '90s and early 2000s. With recent progress in integrating smell into Human-Computer Interaction, questions arise whether a third wave is commencing and if this field will persist or decline. The panel additionally featured a scratch-and-sniff card, accompanying presentations, that I designed.

The “Twitch and Sniff Along” series spotlights video games that have incorporated scent as a modality. We’re presenting several historic games (and maybe new ones!) online and offer free mailed replicas of their scratch and sniff cards for educational purposes. The series has been recognized as a finalist for the 2022 Sadakichi Award for Experimental Work with Scent as part of the 8th Art and Olfaction Awards.
Olfactory art, in particular scented cinema, has consistently been the brunt of dismissive humor. The “Scent in Cinema” series seeks to present works of scented cinema and provide critical discussions of this medium. The events include a virtual screening with mailed scratch and sniff cards followed by a moderated panel discussion with experts in the field. This event aims to (1) increase enthusiasm about the study and creation of olfactory arts, (2) cultivate a better sensory understanding of and critical engagement with smell, and (3) provide connections across several fields. The series has been recognized as a finalist for the 2022 Sadakichi Award for Experimental Work with Scent as part of the 8th Art and Olfaction Awards.

Perfect Melon is a “community-building” marketing campaign from the fictional Perfect Melon beverage corporation, presented as an interactive installation. The corporation’s intention is not to simply sell a soft drink, but to cultivate a consumer community entirely mediated by the corporation. The marketing campaign involves a VR flavor experience, in which attendees enter a pavilion above an infinite melon field and are tasked with finding the “perfect” melon. In VR, attendees assess melon freshness and flavor by slapping them, listening to their sounds, and tasting their unique flavors. Once they select a melon, their choice is folded into the formula for the corporation’s commercial beverage: a mixture of all users’ chosen melons.
As a gift for the Leather Goddesses of Phobos panelists of the Twitch and Sniff Along series, I produced a new "Definitive Sniff Edition" of the text-based adventure. The limited-edition included the mysterious cut 8th odor, two new fragrances hinted at in the original game, a fresh smell puzzle, and a new scratch-and-sniff card based on older designs from the Leather Goddesses of Phobos Infocom Cabinet documents. Each panelist received a scratch-and-sniff card and a copy of the game's fan-made edition.
Download my food is a flavor project that features two components. The first is an offline installation featuring vegan jellies in a mini-fridge with a computer set on top of the fridge. In an attempt to use crowd-sourcing as a means of digitizing the flavor information, visitors try a jelly and fill out a form to collect information on the jelly's flavor: taste, smell, and texture. In turn, their submissions feed into a publicly accessible dataset. Online visitors access a webpage with a single link that reads "download my food," which triggers upon clicking the download of both the recipe as an XML file and the current dataset version.
Sanitary selves is an olfactory VR installation celebrating and critiquing motion capture databases from the 2000s. Audiences engage with the project through immersive smell and sound and interact with the database in a virtual space. The project sought to question the sanitation and omission of identity markers in the databases, asking whether purely abstract movements can exist when steeped in culture.
The installation explores the perceived synthetic emotions derived from traditional, domestic flower preservation. Flowers were cut from their stem, preserved in paraffin wax, and randomly reattached with botanist's tape. A thick paraffin blanket affixes the stems to the Pyrex dish. The flowers waft soft floral, powdery, and woody notes from the addition of Dior Homme.
SAIC graduate-level studio course on Virtual Reality constructed to include a heavy-hand of theory focusing on interactive immersive media topics, in order to push it in the direction of a theory-in-practice structure. Through the course, students considered various artworks and projects realized in virtual reality, and how they inform public consciousness of spaces. Accompanying readings were but a sample of current endeavors meant to open up a common discourse on issues of immersion and human experience, such as metaphors of space, dynamic form in three dimensions, perception and representation, simulation, information, mapping, embodiment, and telepresence. (Syllabus and readings made publicly available.)
This project aims to create a public database of scratch and sniff books. It’s meant to (1) provide information for researchers, authors, and parents interested in purchasing and analyzing existing books or producing their own work, as well as (2) take into consideration olfactory engagement for blind or visually impaired persons (BVIP) – much like tactile graphics, but for smell. This project was an awardee of the Institute for Art and Olfaction's Accelerator Initiative.

CBORG is a collaborative roving research team working to make sensory education and research more widely accessible and politically/artistically valuable to our communities in Chicago. Resting upon the belief that smell is a skill and way of knowing long devalued by systems of power, the group was co-started by researcher Eleonora Edreva and myself with the intention that everyone could use more practice learning through their noses.
