Key Publications from PhD Thesis: Chemical Interfaces

ACM CHI and UIST are the premier venues for technical Human-Computer Interaction (HCI) publications, which are fully peer-reviewed and have an acceptance rate of 20-25%. These are considered top-tier in the field, even when considering HCI journals, and Computer Science is a conference-focused discipline.

Taste Retargeting via Chemical Taste Modulators

Jas Brooks, Noor Amin, Pedro Lopes

🏡️ UIST Jury’s Honorable Mention for Best Demo

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...

Trigeminal-Based Temperature Illusions

Jas Brooks, Steven Nagels, Pedro Lopes

πŸ† CHI Best Paper Award (top 1%)

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... This work received a CHI Best Paper Award (top 1%).

Stereo-Smell via Electrical Trigeminal Stimulation

Jas Brooks, Shan-Yuan Teng, Jingxuan Wen, Romain Nith, Jun Nishida, Pedro Lopes

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... 🏡️ Innovation by Design Honorable Mention

Chemical Haptics: Rendering Haptic Sensations via Topical Stimulants

Jasmine Lu, Ziwei Liu, Jas Brooks, Pedro Lopes

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...

Smell & Paste: Low-Fidelity Prototyping for Olfactory Experiences

Jas Brooks, Pedro Lopes

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... 🏡️ Finalist for 2024 Sadakichi Award (Art & Olfaction)

ThermalGrasp: Enabling Thermal Feedback Even While Grasping & Walking

Alex Mazursky, Jas Brooks, Beza Desta, Pedro Lopes

Most thermal interfaces attach Peltier elements and their required cooling systems (heatsinks and fans) directly to the palm or sole, preventing users from grasping or walking. To solve this problem, we present ThermalGrasp, an engineering approach for wearable thermal interfaces that enables users to grab and walk on real objects with minimal obstruction. Our approach...

Increasing Electrical Muscle Stimulation’s Dexterity by Means of Back-of-the-Hand Actuation

πŸ† CHI Best Paper Award (top 1%)

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,... This work received a CHI Best Paper Award (top 1%).

Elevate: A Walkable Pin-Array for Large Shape-Changing Terrains

Seungwoo Je, Hyunseung Lim, Kongpyung Moon, Shan-Yuan Teng, Jas Brooks, Pedro Lopes, Andrea Bianchi

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...

Third Wave or Winter? The Past and Future of Smell in HCI

Participants: Jofish Kaye, Marianna Obrist, Judith Amores, Jas Brooks

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...
