Generative Muscle Stimulation: Providing Users with Physical Assistance by Constraining Multimodal-AI with Embodied Knowledge

Electrical-muscle-stimulation (EMS) can support physical-assistance (e.g., shaking a spray-can before painting). However, EMS-assistance is highly-specialized because it is (1) fixed (e.g., one program for shaking spray-cans, another for opening windows); and (2) non-contextual (e.g., a spray-can for cooking dispenses…

Modeling Perceived Force of Electrical Muscle Stimulation to Improve User’s Recall

Interactive electrical-muscle-stimulation (EMS) supports motor- skills by actuating the user’s muscles. However, existing EMS- interfaces exclusively focus on demonstrating movements/sequences (e.g., which fingers to actuate to play a piano melody) and have not investigated EMS for skills requiring precise force a…

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…

SplitBody: Reducing Mental Workload while Multitasking via Muscle Stimulation

Techniques like electrical muscle stimulation (EMS) offer promise in assisting physical tasks by automating movements, e.g., shaking a spray-can or tapping a button. However, existing actuation systems improve the performance of a task that users are already focusing on (e.g., users are already focused on using the sp…

ecoEDA: Recycling E-waste During Electronics Design

The amount of e-waste generated by discarding devices is enormous but options for recycling remain limited. However, inside a discarded device (from consumer devices to one’s own prototypes), an electronics designer could find dozens to thousands of reusable components, including microcontrollers, sensors, voltage reg…

JumpMod: Haptic Backpack that Modifies Users’ Perceived Jump

Vertical force-feedback is extremely rare in mainstream interactive experiences. This happens because existing haptic devices capable of sufficiently strong forces that would modify a user’s jump require grounding (e.g., motion platforms or pulleys) or cumbersome actuators (e.g., large propellers attached or held by t…

DigituSync: A Dual-User Passive Exoskeleton Glove That Adaptively Shares Hand Gestures

We engineered DigituSync, a passive-exoskeleton that physically links two hands together, enabling two users to adaptively transmit finger movements in real-time. It uses multiple four-bar linkages to transfer both motion and force, while still preserving congruent haptic feedback. Moreover, we implemented a variable-…

DextrEMS: Achieving Dexterity in Electrical Muscle Stimulation by Combining it with Brakes

Electrical muscle stimulation (EMS) is an emergent technique that miniaturizes force feedback, especially popular for untethered haptic devices, such as mobile gaming, VR, or AR. However, the actuation displayed by interactive systems based on EMS is coarse and imprecise. EMS systems mostly focus on inducing movements…

MagnetIO: Passive yet Interactive Soft Haptic Patches Anywhere

We propose a new type of haptic actuator, which we call MagnetIO, that is comprised of two parts: one battery-powered voice-coil worn on the user’s fingernail and any number of interactive soft patches that can be attached onto any surface (everyday objects, user’s body, appliances, etc.). When the user’s finger weari…

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…

Touch&Fold: A Foldable Haptic Actuator for Rendering Touch in Mixed Reality

We propose a nail-mounted foldable haptic device that provides tactile feedback to mixed reality (MR) environments by pressing against the user’s fingerpad when a user touches a virtual object. What is novel in our device is that it quickly tucks away when the user interacts with real-world objects. Its design allows…
