Increasing Input Accuracy of Embodied Devices via Electrical Muscle Stimulation

This paper evaluates interaction techniques to increase input accuracy with embodied devices—an emergent type of interactive system where the user's body serves as both the input and output medium (e.g., gestural input via cameras/IMUs; gestural output via motors/muscle stimulation). A shortcoming of existing embodied…

Mid-Air Gestures for Proactive Olfactory Interactions in Virtual Reality

Olfactory experiences are increasingly in demand due to their immersive benefits. However, most interaction implementations are passive and rely on conventions established for other modalities. In this work, we investigated proactive olfactory interactions, where users actively engage with scents, focusing on mid-air…

Adaptive Electrical Muscle Stimulation Improves Muscle Memory

Electrical muscle stimulation (EMS) has been leveraged to assist in learning motor skills by actuating the user’s muscles. However, existing systems provide static demonstration—actuating the correct movements, regardless of the user’s learning progress. Instead, we contrast two versions of a piano-tutoring system: a…

Augmented Breathing via Thermal Feedback in the Nose

We propose, engineer, and study a novel method to augment the feeling of breathing—enabling interactive applications to let users feel like they are inhaling more/less air (perceived nasal airflow). We achieve this effect by cooling or heating the nose in sync with the user’s inhalation. Our illusion builds on the phy…

Taste Retargeting via Chemical Taste Modulators

Prior research has explored modifying taste through electrical stimulation. While promising, such interfaces often only elicit taste changes while in contact with the user’s tongue (e.g., cutlery with electrodes), making them incompatible with eating and swallowing real foods. Moreover, most interfaces cannot selectiv…

Smell & Paste: Low-Fidelity Prototyping for Olfactory Experiences

Low-fidelity prototyping is so foundational to Human-Computer Interaction, appearing in most early design phases. 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 t…

Chemical Haptics: Rendering Haptic Sensations via Topical Stimulants

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, which contain safe and small doses of key active ingredients, receptors in the user’s skin are chemically triggered, rendering dist…

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

Current head-mounted displays enable users to explore virtual worlds by simply walking through them (i.e., real-walking VR). This led researchers to create haptic displays that can also simulate different types of elevation shapes. However, existing shape-changing floors are limited by their tabletop scale or the coar…

Stereo-Smell via Electrical Trigeminal Stimulation

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 t…

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

We propose a technique that allows an unprecedented level of dexterity in electrical muscle stimulation (EMS), i.e., it allows interactive EMS-based devices to flex the user’s fingers independently of each other. EMS is a promising technique for force feedback because of its small form factor when compared to mechani…

Trigeminal-based Temperature Illusions

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 trige…
