Download my CVI am Jiachen Li, a current CS PhD student at Northeastern University. Prior to it, I have a Master's degree in Digital Media at Georgia Tech, and a Bachelor's Degree in Electronic Engineering.
My research centers on examining the role of AI assistants in people's everyday experiences, with a particular emphasis on understanding the gap between current technology and human expectations in healthcare settings. My primary focus has been on the contexts of daily routine management and healthcare & wellness for older adults (OAs) with the help of passive personal tracking and LLM.
Recent:
1) Sense-making for multi-modal personal health sensing data with visualization and LLM (CHI submissions)
2) Creating LLM agents that can simulate daily behaviors of OAs
- Profile, schedule & routine, raw sensor data, social interactions
3) Providing support to OAs and their care networks with the help of LLM
- Daily summaries, JIT interventions, Caregivers collaboration
4) Visual and voice AI assistant in assisting cooking tasks and routines for OAs with cognitive impairment.
I had my bachelor's degree in Electronics Information Technology and decided to pursue a master’s degree in Digital Media after graduation. Due to my previous experience, I highly value creativity and intuition in the design and research process more than many engineers, however, I still regard myself as a logical and rational person. As a result, I would like to apply scientific and epistemological methods as the main part of my future research and combine them with design synthesis and abductive reasoning to generate valuable insights.
To know more about me, I'm a doll maker, a figure maker and collector. I work with clay, mostly modeling clay and polymer clay. I also do figure coating, moldering and casting. In my spare time, I travel, read and photograph. I love cats, have been living with six cats before (four of them are my cats: Leo, Lily, Jacob and Echo).

Phase Transition Actuator
PITAS: Sensing and Actuating Embedded Robotic Sheet for Physical Information Communication
(CHI 2022)
Abacus, as a traditional Chinese physical calculator, has an irreplaceable position in pre-k and primary school mathematics education. We designed and developed a physical interaction system that enabled children to study the principle of mathematical calculation through the process of abacus learning.
In this paper, we investigate the problem of video-based parent-child relationship prediction via human face analysis. Most of the existing kinship verification methods are based on single images; these approaches cannot effectively utilize videos of the face for kinship verification. We propose our own dataset, Familyship Fa...
Designed unintentional touch detection algorithm based on 125Hz capacitive sensing signal on phone.
Used flood-fill algorithm and ellipse fitting techniques to detect touch, and performed FFT analysis and generated the frequency spectrum.
Inspired by ancient cuneiform that uses imprints on the clay for documentation, we built a tangible user interface using clay boards, conductive paints and digital animation with narratives to distance the physical from the digital.
We designed a tangible system that used biological signals (EMG, heart rate, etc.) to increase body awareness in yoga practice and created an interactive figurative animation as representation and visualization of bodily data.
We aims to create a solution to enhance empathy between people with MCI (Mild Cognitive Impairment) and those around them, and we provide a service that promotes activities between the MCI patients and caregivers using subscription boxes called the “Empatea Box”, which will be regularly delivered to the home address of the MCI patient's family and involve loose lea...
The project aims to study how to design a research project website that enables different users to find a variety of information and accomplish different tasks. We designed a project website for Code-Crafter, a research project that investigates connections between quilting and computational thinking.
"Whenever clay encounters with other objects, there would be traces and imprints left on the surface.”
Have you ever thought about taking a picture using clay?
Inspired by the way students communicate their thoughts with chalk on sidewalk tiles on campus, we hope to create a digital sidewalk in the form of an interactive web page, where a student can share their personal stories during COVID(and beyond) on a sidewalk tile and have an opportunity to empathize, resonate, and reconnect with each other. We aim to provide people a way of communication and connection through the format of digital craft.
Newscity is a word processor that retrieves the text entered by the user and outputs the same content in different sizes and colors according to the data from NY Times API, including the number of related articles, categories and other data. By continuously inputting different vocabulary, users can work with NY Times to build a unique 'news city' that belongs to them but also influenced by external information.
A device was created to allow people to experience an overwhelming negative interaction of another person using a helmet with vibration motors, a resistive heater, LEDs, and a servo motor. Users can have a better und...
People spent a long time in front of the mirror but never noticed it. I hope to make people aware of the existence of the mirror, and furthermore, not only regard it as an object but more as a creature with life and soul. Cat Mirror is a unique mirror that can perform differently ac...
EduFirst is a game that simulates an education-oriented society. At the beginning of the game, the player is told that the goal of judging whether the game is successful is whether your child can enter a good university, and this is closely related to his various points on “Knowledge”, “Patience” and “Concentration”. In this game, players consume their “Ability” points to ask their children to co...
Every semester, college students need to buy textbooks for their classes. At the end of the semester, they often no longer need the books. TextEx is an online platform for UC Berkeley students to buy and sell their used textbooks and engage in textbook exchange with other students.
Designed UI and wearable for an app that detects the stress level of people and helps them release stress. Used different features such as layout, weight, typography and color to distinguish two stress levels.
