짧은 여정.

첫 학회) 라자스탄 - 조드뿌르 -> 뉴델리

기껏 3일..

돈과 시간만 주어진다면...

빡세게 공부하고 빡세게 돈벌어서 제대로 다녀오자!

우리 학교 천연 무공해 자연산 눈썰매장

 

 

학교 과학 도서관 뒤 언덕길..

눈이 엄청 내린 날 누군가 친절하게도 길을 내어 눈썰매장을 만들었다.

덕분에 이 길을 지나치는 사람은 걷지 않고 앉아야만 갈 수 있다.

Brain-computer interface for Second Life

Brain-computer interface for Second Life

12 Oct 2007

While recent developments in brain-computer interface (BCI) technology have given humans the power to mentally control computers, nobody has used the technology in conjunction with the Second Life online virtual world — until now.

A research team led by professor Jun’ichi Ushiba of the Keio University Biomedical Engineering Laboratory has developed a BCI system that lets the user walk an avatar through the streets of Second Life while relying solely on the power of thought. To control the avatar on screen, the user simply thinks about moving various body parts — the avatar walks forward when the user thinks about moving his/her own feet, and it turns right and left when the user imagines moving his/her right and left arms.

The system consists of a headpiece equipped with electrodes that monitor activity in three areas of the motor cortex (the region of the brain involved in controlling the movement of the arms and legs). An EEG machine reads and graphs the data and relays it to the BCI, where a brain wave analysis algorithm interprets the user’s imagined movements. A keyboard emulator then converts this data into a signal and relays it to Second Life, causing the on-screen avatar to move. In this way, the user can exercise real-time control over the avatar in the 3D virtual world without moving a muscle.

Future plans are to improve the BCI so that users can make Second Life avatars perform more complex movements and gestures. The researchers hope the mind-controlled avatar, which was created through a joint medical engineering project involving Keio’s Department of Rehabilitation Medicine and the Tsukigase Rehabilitation Center, will one day help people with serious physical impairments communicate and do business in Second Life.

2010년

결코 돌아오지 않을 것 같은 해가 왔다.

그런데 작년 이때와 다르지 않다.

내가 각성해야 여기에 머무르지 않을텐데..

새해 처음으로 힘내보자!!
