Editor's Notes
- With emergence of useful sensing applications, you can imagine that our life spaces will be inevitably filled with rich sensor devices. Already popular smartphones, [PRESS] emerging wearable devices like glass and watch, and [PRESS] also space-embedded sensors, and the sensors of other people inside the space. (Accelerometer Ambient light Bluetooth Camera GPS Magnetometer Microphone Proximity)
- How can we handle these complicated problems? There would be no magic solution to solve the problem in a single shot. But one thing I am sure of is that system-level support is essential and we should not impute burden to the applications. [PRESS] In this regard, my overall research vision has been to build full-fledged context monitoring platform. [PRESS]With the platform support, applications can simply query the system to monitor rich user contexts. On behalf of applications, the platform abstracts the sensing devices and [PRESS] resolves the previously mentioned resource challenges. I think in the near future, this platform would be core functionality of commodity mobile operating systems.
- I can put many of my research work, in the perspective of cooperative planning. [PRESS] In earlier papers like MobiCon, Orchestrator and SeeMon, I propose systems to make multiple personal sensing devices cooperatively support concurrent sensing applications (to reduce battery consumption, address resource conflicts and dynamics) [PRESS] Furthermore, I extended cooperation scope to collocated users and propose the system called CoMon that enables cooperation among multiple users. [PRESS] Recently, as the importance of smartphone itself is hugely growing, I studied about resource coordination among concurrent apps on a smartphone.
- Let’s look at my research with a broader view. My research has focused on the resource-related issues so far, but to build a full-fledged platform I had to face with far more diverse issues, as you see some of the examples in this figure. I think a lot of issues are still open, and hope to collaborate with many people here. Game video

- 하지만, 바쁜 일상 속에서 살아가는 현대인들에게 있어서 이러한 소셜 스포츠를 즐기는 것은 참으로 어려운 일입니다. 따라서, 자연스럽게 사람들은 혼자서 할 수 있는 트레드밀 달리기와 같은 운동을 선택합니다. 그렇지만, 이러한 단조롭고, 반복적이고, 고독한 운동은 팀 스포츠가 주는 만큼의 재미있고 아찔한 경험을 주지는 않습니다. 바로 여기에서부터 제가 하고자 하는 연구가 시작됩니다. 어떻게 하면 혼자서 하는 운동을 재미있는 활동, 이를테면 게임, 으로 바꿀 수 있을까? 하는 것입니다.
