Human-centered Intelligent Systems Lab
We are looking for highly motivated students who are passionate about exploring first-of-a-kind, smart, little but mighty systems to be interwoven with our real life, in the areas of Mobile Computing, Human-Computer Interaction, and Applied AI. If you are interested, or would like to chat about any ideas, please just drop an email to Inseok at "i.hwang at postech.ac.kr"
Mission
Our group explores novel AI-infused human-centered systems that foster computing-rich human life, at the intersection of human-computer interaction, mobile computing, and applied machine learning.
In this light, our research mission is to create novel human-centered intelligent systems and applications to advance real-life human abilities and experiences, fueled by highly autonomous, cognitive, and ubiquitous agents, yet whose existence mostly stays unobtrusive. Our research is an interdisciplinary ensemble of computing systems, artificial intelligence, connected things, and real-life human factors, e.g., physical, emotional, cognitive & social.
From applications & human-factor perspectives, we disrupt our real-life problems by building and deploying first-of-a-kind AI-powered computing applications in various domains of (but not limited to) health & wellbeing, family & childcare, aging, and supporting underrepresented social groups.
From systems perspective, we think-ahead and design next-generation mobile/edge software platforms to accommodate highly usable machine intelligence and autonomously serve newly emerging real life-driven computing workloads.
