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 daily practices. This encompasses situations where people's expectations surpass the current technological limitations, leading to potential failures and frustrations. Additionally, it explores scenarios where technology's capabilities exceed human perception, thereby unlocking new potentials for AI to assist individuals in various capacities. My primary focus has been on the contexts of daily routine management and healthcare & wellness. (recently: LLM for collaboration in healthcare settings for older adults). I have conducted research involving diverse groups, including older adults and college students.
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).
Now you can literally ask your smart home speaker anything, so, what's next?
- Cooking instructions & Recipe
- Routine management
- Personal Therapist

Medication non-adherence is a widespread issue globally, particularly among college students with mental health issues who require daily scheduled medication. Self-reporting is a common and cost-effective method to monitor medication behavior, but its impact on medication adherence is still unknown. Additionally, despite the complexity and variability of medication routines, which are highly influenced by personal experiences, limited research has focused on the individual choices of reporting instruments in different contexts. This research aims to provide different self-report channels to college students and explore how they use the systems in diverse settings.
Preparing meals can be a complex task for seniors who suffer from cognitive impairment, as well as for researchers who attempt to understand their behaviors. By incorporating a self-check-in system for meal times, seniors may be able to better regulate their meal preparation routines. Moreover, with access to the check-in data, AI researchers may be able to more accurately label sensor data, leading to improved analysis of senior behavior.

We present PITAS, a thin-sheet robotic material that consisted of a phase transition actuating layer and a heating/sensing layer for non-expert makers to create their own devices that could remotely communicate physical information. We explored and reported the mechanical and electrical properties of the material...

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.

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.

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.

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.
