About Me

I am Ryuhaerang Choi, a master student who aims for a system that can permeate people’s daily lives and make life more prosperous. I am studying at the Networking & Mobile Systems Lab at KAIST. People today have mobile devices all the time, so these devices are the right platforms to create the system I want to build. So, I am interested in mHCI for valuable interaction between digital devices and people, mHealth which can be an accessible medical tool, and ubiquitous sensing with mobile devices and network-connected objects around us.

Research Interests and Projects

Mobile HCI


Human-computer interection (HCI) studies the interaction between humans and computers including both HW and SW. One of the objectives of mHCI is to build a mobile system to improve the quality of human life.

Mobile Health


Mobile healthcare industry has been in the limelight for years. mHealth is the term used for health-related service supported by mobile devices. The examples of mHealth applications are provision of medical information to patients, real-time monitoring of biometric signal, telemedicine, etc.

Ubiquotous Sensing

Ubiquitous sensing means utilizing network-connected digital sensors in a given environment. We can detect amount of light, amplitude of sound, frequency of vibration, etc. The combination of ubiquitous sensing and ML can make objects around us intelligent.
