Hi, I am Dario Liu
I am a second-year Master's student specializing in HCI at the University of Maryland. I am interested in the topics related to regulate daily emotions, stress, behavior change. Under the guidance of Dr. Pablo Paredes and Dr. Ashock Agrawala at the Pervasive Wellbeing Tech Lab and Mind Lab, I've cultivated an interest in designing affective computing technologies, embodied technologies that facilitate behavioral changes, aiming to enhance pervasive well-being for individuals.
I am also interested in Human- AI interaction. With the rise of Artificial Intelligence (AI) in the modern world, I'm intrigued by the evolving interaction between humans and AI. This dynamic prompts questions about our trust in AI and how we can design interactions to enhance both efficiency and convenience in our daily lives.
This study explores the potential of haptics, touch-centric technology that employs tactile feedback in digital interfaces to emulate physical sensations, in augmenting the individual’s cognitive performance under stressful conditions such as examination, interview, or presentations. Understanding the correlation between biorhythms and arousal changes, we devise a pseudo-breathing signal with specific patterns at faintness level, implemented via haptics embedded in a chair. Our research involves lab-controlled experiments with heartbeat counting tasks, stress-induced tasks, cognitive tasks, and haptic interventions. We hypothesize that pseudo-breathing signals generated by haptics intervention will boost an individual's cognitive performance in stressful environments, irrespective of the participants’ participants’ interoceptive accuracy. We hypothesize that exposure to a haptic-based pseudo-breathing signal leads to the synchronization of physiological metrics like breathing and heart rate. This synchronization is predicted to boost cognitive performance during stress, regardless of an individual's ability to perceive their internal bodily sensations, termed as interoceptive accuracy (IA). Findings from this study promise to provide insights and inform design directions for leveraging haptic technology to enhance cognitive performance within high-stress environments.
UX Design Project
The Air-Finder innovative concept aims to assist individuals who are in a hurry to locate items that they may have misplaced within their living environment. The goal of our concept is to provide users with a time-effective, convenient, and reliable navigator to help them find their lost belongings within the comfort of their own home.
UX Design Project
Our original concept was focused on designing the interfaces required for an application based in-vehicle experience, this includes; a reservation system, interface customization, and in-vehicle use of our application. We want to design a dynamically adapting interface for vehicle renters to safely interact with a vehicle's speed, navigation, entertainment, temperature, and other in-vehicle systems.
UX Research Project
In our User Research Method course, we completed a UX research project for an external client, addressing stressors related to finances faced by international students during transitions between countries, schools, and jobs. Using our research findings, we provided the client with recommended solutions to better support these students.
Human-Robot Interaction: Care Compainion
UX Research & Conversation Interface Project
With the world's population aging, younger generations are spending less time with their families, leaving older generations at risk of loneliness, falls, and depression during the rehabilitation process. During my first job, I worked on a project focused on building a care companion robot to address these issues by targeting fall prevention, rehabilitation, and stress management for elderly individuals.
