Human-AI Interaction & Symbiosis
AI is rapidly becoming a commodity in every area of computing, and computing is already a commodity of everyday human life. Thus, we think ahead about the next logical step -- AI being a commodity of everyday human life. No one can exactly tell what such an AI-rich human life would look like. But the easiest way to tell some is to be a few who create a bit of its initial look. We explore various embodiments in which AI boosts everyday human-life agenda -- family, community, health, social, etc. One step further, we also investigate the other way -- unique human factors boost everyday AI. Putting both together, we envision Human-AI Symbiosis.

Pervasive Sensory Augmentation for Interactive Everyday Spaces
Sensing is the cognitive gateway that opens up our everyday real-life spaces for computerization. The ever-proliferating commodity mobiles and wearables are paving a new layer of pervasive sensing, expediting the deployment in a practical and affordable manner. We explore brand-new, cost-minimal, and widely usable opportunities to turn our everyday space into one full of interactive gadgets and agents.

Mobile Extended Reality (XR) & Telepresence: Future of Human Presence
Physical presence is the basis for our real-life existence, social activities, and live experiences. However, a global pandemic or physical impairments threaten such a basis, severely limiting our real-life ability, quality of life, and even economy. We envision new technologies and designs to innovate the conventional model of human presence, to augment and extend real-space human ability, and furthermore, to drive the transcendence beyond our natural-born constraints as physical beings.

IoT-powered Real-world Social Computing
Over the last decade, online social platforms opened up trillion-dollar businesses, reshaped the ways we meet & work, and even catalyzed new fields of science to emerge. We strive to unfold the next leap of social platforms, which are now homed in the real world, powered by tiny smart things on and around us, helping our real social life healthier & enjoyable, empowering us to interact in unprecedented ways, and providing new labs and markets to social scientists and entrepreneurs, respectively.

On-device AI: Acceleration for Pervasive AI
These days, at every blink of an eye, we are witnessing a new advance of artificial intelligence (AI) and deep learning technologies. Imagine our body, personal space, and social space soon to be full of intelligent things and empowered by intelligent services. In this light, our missions are: (1) to spur the evolution of mobile & wearable computing platforms to accommodate machine learning principles and embodiments to be more efficient, usable, and interactive; (2) to premiere first-of-a-kind services powered by AI and deep learning on tiny platforms in various facets of our everyday life.
