I am Chi-Lan (期蘭), a doctoral student conducting HCI/CSCW research with Prof. Narumi (advisor) and Prof. Kuzuoka (co-advisor) at Cyber Interface Lab, the University of Tokyo. My doctoral research explores and supports remote collaboration among distributed members in workplaces through computer-mediated communication (CMC) technologies.

My research tackles how people form perceptions and interact with each other through the mediation of information technology, for the purpose of building and maintaining different types of social relationships online. Specifically, I investigate how various social cues shape human perception and behavior in remote communication. The overall goal is to reshape attribution process between remote interlocutors and support impression management by the design of CMC technologies.

Apart from research activities, I explore a different world by reading novels, writing popular science about HCI topics, sketching, and searching for hot springs in Japan ♨️.

I have been trained as an HCI (Human-Computer Interaction) researcher from the Institute of Information Systems and Applications (ISA) at National Tsing Hua University in Taiwan since 2015.

In the past few years, I had been collaborated with and advised by Prof. Hao-Chuan Wang from the Department of Computer Science at UC Davis since 2014. I was also co-advised by Prof. Chien-Wen (Tina) Yuan since 2017. We worked together on exploring the topic of computer-mediated knowledge transfer and knowledge sharing.

Before stepping into the world of HCI, I received a Bachelor’s degree in Psychology from National Cheng Kung University and had been conducting cognitive science research as a research assistant at the Institute of Cognitive Neuroscience at National Central University.

Broadly speaking, my research interests lie in the intersection of computer-mediated communication, computer-supported cooperative work and social computing. The overall goal of my research is to better understand how intelligent information technologies shape human cognition and behavior individually and collectively. Currently, I am working on exploring how different types of social cues shape people's perception of their remote counterparts and the attribution process when people have social interactions online (e.g., video call, text chat, audio chat, social virtual reality)

Other than doing research, I also spend some time writing Chinese articles to introduce HCI/CSCW (Computer Supported Cooperative Work and Social Computing) research to the general audiences. Take a look here. Also, I sometimes sketch to express my feeling and observation of my daily life.

Distance Matters to Weak Ties: Exploring How Workers Perceive Their Strongly- and Weakly-Connected Collaborators in Remote Workplaces

Chi-Lan Yang, Naomi Yamashita, Hideaki Kuzuoka, Hao-Chuan Wang, Eureka Foong.

[PDF] (Appeared in PACM HCI GROUP'22)

In this study, we found that remote workers depended on one-on-one synchronous tools to infer the engagement level of strong ties, but used group-based communication tools to infer the engagement level of weak ties during working from home. The absence of cues in remote workplaces exacerbated prior impressions formed in the physical office. Our findings showed that remote work led workers to form polarized perceptions of their respective ties.

When Knowledge Network is Social Network: Understanding Collaborative Knowledge Transfer in Workplace

Chi-Lan Yang, Chien-Wen (Tina) Yuan, Hao-Chuan Wang [CSCW'19]

With a mixture of field observations, social network analysis, and in-depth interviews, we found that there is a discrepancy between inbound and outbound knowledge transfer and scaffolding workers to connect to the right person with metaknowledge of the knowledge network is essential.

Knowing That You Know What I Know Helps? Understanding the Effects of Knowledge Transparency in Online Knowledge Transfer

Chi-Lan Yang, Chien-Wen (Tina) Yuan, Tzu-Yang Wang, Hao-Chuan Wang [CSCW'18]

In this study, we demonstrate that visualizing the understanding level of the remote learner benefits communication quality between the remote instructor and learner as they transfer knowledge online.

This work had been shared at the poster session at IUI, 2018, and is still an ongoing project.

Can You Help Me without Knowing Much? Exploring Cued-Knowledge Sharing for Instructors’ Tutorial Generation

Chi-Lan Yang, Hao-Chuan Wang [IUI'18]

This work tries to investigate cued-knowledge sharing, which pairs instructors with partners of different levels of expertise who also participate in the tutorial generation and give cues (prompts, questions) to the instructors to facilitate their knowledge externalization.

Task Hand Over in the Workplace

We propose a triangular relationship among human, artefacts, and context during task transfer by referring to the theory of distributed cognition.

How Social Annotation Affects Second Language Reading

In this work, we simulated the process of social annotation and examined how seeing others’ annotations affects readers’ understanding of the content as well as their production and editing of annotations.

(CSCW'16 Poster)

This work was mainly lead by Tina Tu and Mei-Ling Chen, and has been shared during the poster session at CHI, 2016.

Co-Viewing Room: Mobile TV Content Sharing in Social Chat

In this work, we present a mobile TV content sharing system called Co-Viewing Room, which enables distributed users to share three types of TV content, including it whole video sharing, video clips sharing and it snapshots sharing during an online chat.

Looking for something exciting | 尋找合作夥伴!

Research collaborators

I am looking for collaborators who have interests in building novel interaction systems. As you can see from my background and personal interest, my skill sets and interests are mostly about understanding human behavior but not having much interest in implementing systems. If you are passionate about building systems to understand HCI topics around the following topics: remote collaboration, remote communication, HRI, human-ML(AI) interaction, online learning, cross-lingual communication, knowledge sharing, online community, etc., please do not hesitate to contact me! I believe we can contribute to HCI research together by integrating different perspectives and expertise. The research outcome does not necessarily have to be a research paper. As long as we can work together to empower humans and make human be more reflective and creative is excellent enough.
