Towards Unobtrusive Physical AI: Augmenting Everyday Objects with Intelligence and Robotic Movement for Proactive Assistance

Users constantly interact with physical, most often passive, objects. Consider if familiar objects instead proactively assisted users, e.g., a stapler moving across the table to help users organize documents, or a knife moving away to prevent injury as the user is inattentively about to lean against the countertop.…

Transforming Everyday Objects into Dynamic Interfaces using Smart Flat-Foldable Structures

Dynamic physical interfaces are often dedicated devices designed to adapt their physical properties to user needs. In this paper, we present an actuation system that allows users to transform their existing objects into dynamic physical user interfaces. We design our actuation system to integrate as a self-contained l…

A Dynamic Bayesian Network Based Framework for Multimodal Context-Aware Interactions

Multimodal context-aware interactions integrate multiple sensory inputs, such as gaze, gestures, speech, and environmental signals, to provide adaptive support across diverse user contexts. Building such systems is challenging due to the complexity of sensor fusion, real-time decision-making, and managing uncertaintie…

Robotic Metamaterials: A Modular System for Hands-On Configuration of Ad-Hoc Dynamic Applications

We propose augmenting initially passive structures built from simple repeated cells, with novel active units to enable dynamic, shape-changing, and robotic applications. Inspired by metamaterials that can employ mechanisms, we build a framework that allows users to configure cells of this passive structure to allow it…

Parametric Haptics: Versatile Geometry-based Tactile Feedback Devices

Haptic feedback is important for immersive, assistive, or multimodal interfaces, but engineering devices that generalize across applications is notoriously difficult. To address the issue of versatility, we propose Parametric Haptics, geometry-based tactile feedback devices that are customizable to render a variety of…
