Projects

Dec. 2018 – Feb. 2019
In collaboration with Jincheul Jang, Younghyun Hong, and Prof. Mun Yi

• Investigated the role of smart speakers in multi-device collaboration context by interviewing heavy users of smart speakers connected with multiple IoT devices.
• The key finding from this study is that although people generally use the agents for performing multiple tasks, the social role of agents as a ‘companion’ can be also crucial. I also learned that system transparency plays a critical role for users especially in the context of IoT and chatbot.

Sep. 2017 – Sep. 2018
In collaboration with Jongwon Kim, Sangkeun Park (best mentor!), Prof. Mun Yi, and Prof. Uichin Lee
In extension of Human-Computer Interaction project 

• Investigated misinterpretation of stickers in instant messenger with survey and interviews and derived design implications.
