About Chanyou Hwang

I am a Ph.D. student at KAIST, School of Computing.
My research interests are in the areas of Mobile and Ubiquitous Computing. I'd like to add more functions and reduce inconveniences in the computing devices.
One of my specialty and hobby is prototyping. Since my father is an awesome engineer (he developed the first computer embroidering machine in Korea), I have had many chances to handle computers and hardwares from my childhood. Those experiences made me love to make prototypes.
I enjoy playing sports, especially baseball.

I am pursuing a doctoral degree under the supervision of Prof. Junehwa Song in NCLab

Project

I have worked on the projects listed below.

RAVEN:Perception-aware Optimization of Power Consumption for Mobile Games

FROG:Frame Rate Optimizer for Mobile Games

FROG RAVEN is the first system for optimizing rendering rate in mobile games by leveraging human visual perception. The system reduces game app's rendering rate whenever the succeeding frame is predicted to be perceptually similar enough. As a result, it optimizes the power consumption of mobile games without any modification of codes or binaries like a black magic!

TalkBetter

TalkBetter is a system for helping children with language delay. Language delay is a problem of children who do not acquire the expected level of language at their ages. It can become a lifelong risk factor if the children are not treated on right time. Through proper conversations between the children and their parents, language delay can be cured. The parents should be cautious in their conversation. TalkBetter helps parents to improve their conversation habit in daily parent-child-conversation. It intervenes in the conversations and points out the bad language habits of parents in real-time.

SocioPhone

SocioPhone is a platform for monitoring people's conversations to support the interaction-aware applications in daily life. The system monitors conversation of people and extracts the meta-linguistic contexts that provide useful information about conversations excluding semantics which causes privacy problems. For people to use the system in daily life, the system should be energy efficient and robust. To achieve the requirements, we developed the volume-topography-based method for conversation monitoring. The method leverages multiple phones in same conversation session and makes a 'volume-topography' to detect the turn-taking which is the building block of conversation.

Carpool Network

Carpool Network is a novel route-based carpool matching system.
In those days(2011), carpool matching services were region-based. They just matched the people who have similar destination and departure point simply. This approach makes some burden for users. They need to estimate the amount of detour distance when they are inviting or joining in a carpool. Also, it makes them to miss the chance to carpool in the middle of a route. To remedy this, we developed the system, Carpool Network.
