HaptEx: Investigating Haptic Notification Channels for Exoskeletons Across Different Levels of Actuation

Exoskeletons are increasingly deployed in real-world contexts, where communicating critical system states or unexpected events is important for effective interaction. Haptic feedback offers a direct communication channel, integrating naturally with the actuated body region. Yet, it remains unclear how well haptic feed…

Forefeel the Move: Investigating Proprioceptive Feedback for Communicating Imminent Motions of Body-actuating Systems

Systems actuating the body can proactively assist users in diverse tasks. However, unexpected body actuation may pose safety risks. We propose proprioceptive feedback to inform users about an imminent actuation before the system takes control. In a user study, we compare different proprioceptive cues that either inter…

RoboHaptics: Designing Haptic Interactions for Lower Body with Quadruped Robot Dogs

Extended Reality (XR) has advanced audiovisual immersion, yet haptic feedback, especially for the lower body, remains limited. We present RoboHaptics, the first system to explore lower-body haptics using commercial quadruped robots. RoboHaptics leverages its freestanding and reconfigurable nature to deliver both activ…

User-reconfigured Haptics: Combining User-Reconfiguration and Visual Manipulations to Enhance Dynamic Passive Haptic Experiences for VR

Virtual Reality (VR) depends on haptic feedback to create immersive experiences. Traditional passive proxies align physical props with their virtual counterparts but remain limited in scalability and expressiveness, or require bulky actuators to support reconfiguration. We introduce User-reconfigured Haptics, an appro…

Scene2Hap: Generating Scene-Wide Haptics for VR from Scene Context with Multimodal LLMs

Haptic feedback contributes to immersive virtual reality (VR) experiences. However, designing such feedback at scale for all objects within a VR scene remains time-consuming. We present Scene2Hap, an LLM-centered system that automatically designs object-level vibrotactile feedback for entire VR scenes based on the obj…

Move with Style! Enhancing Avatar Embodiment in Virtual Reality through Proprioceptive Motion Feedback

In virtual reality (VR), users slip into a variety of roles, represented by a rich diversity of avatars that each exhibit specific visual attributes and motion styles. While users can see their avatar's motion in VR, they usually cannot feel it. To enhance avatar embodiment, we propose active proprioceptive feedback t…

eTactileKit: A Toolkit for Design Exploration and Rapid Prototyping of Electro-Tactile Interfaces

Electro-tactile interfaces are becoming increasingly popular due to their unique advantages, such as delivering fast and localised tactile response, thin and flexible form factors, and the potential to create novel tactile experiences. However, insights from a formative study with typical designers highlighted the lac…

SparseEMG: Computational Design of Sparse EMG Layouts for Sensing Gestures

Gesture recognition with electromyography (EMG) is a complex problem influenced by gesture sets, electrode count and placement, and machine learning parameters (e.g., features, classifiers). Most existing toolkits focus on streamlining model development but overlook the impact of electrode selection on classification…

GestureCoach: Rehearsing for Engaging Talks with LLM-Driven Gesture Recommendations

This paper introduces GestureCoach, a system designed to help speakers deliver more engaging talks by guiding them to gesture effectively during rehearsal. GestureCoach combines an LLM-driven gesture recommendation model with a rehearsal interface that proactively cues speakers to gesture appropriately. Trained on exp…

LightLink: Enhancing Smartwatch Sensing and Actuation Through Visible Light Communication

Smartwatches are equipped with fixed sensors (e.g., ECG, IMUs) or actuators designed for a broad audience. However, some users need specialized smartwatch functionality, creating a demand for add-on devices that extend a smartwatch's capabilities. Our work explores the design of add-on devices that communicate with th…
