Description

******* 2020/2019-2018 데이터 업데이트: 2023. 2. 2 ******************************************

1. 실험자의 인구통계학적 정보가 수정되었습니다. (성별, 나이, 주사용 손, 키, 몸무게)

******* 2020/2019-2018 데이터 업데이트: 2022. 3. 17 ******************************************

1. 실험자의 인구통계학적 정보가 추가되었습니다. (성별, 나이, 주사용 손, 키, 몸무게)

2. 매일 오전 실험 시작 시 (AM), 그리고 실험 종료 시 (PM) 입력한 수면 관련 설문조사의 결과가 추가되었습니다.

3. Withings Sleep Mat (2020), Actigraph (2019), Fitbit Versa (2018)로 수집한 수면 측정 데이터가 추가되었습니다.

아래 본문의 설명을 참고하시기 바랍니다.

*******************************************************************************************************

일상생활 중 다양한 경험상황을 이해하기 위해 멀티모달 센서를 활용한 라이프로그 데이터셋을 구축하였습니다.

2020년 22명, 2019년 20명, 2018년 30명의 실험자로부터 총 1,285일의 실험일 동안 약 14,220시간의 데이터를 수집하였습니다.

데이터셋은 스마트폰의 IMU 및 GPS 데이터, E4의 가속도계, PPG, EDA, 서모파일 센서로부터 측정한 다양한 생리반응 신호,

그리고 사용자가 직접 입력한 행동, 환경, 및 감정 레이블을 포함합니다.

2020 데이터셋은 다음의 데이터를 포함합니다.

==================================================================================================

- Triaxial acceleration force (in m/s^2) from the mobile phone accelerometer (30 Hz) and E4 accelerometer (32 Hz)

- Triaxial rate of rotation (in rad/s) and degrees of rotation (in Degrees) from the mobile phone gyroscope (30 Hz)

- Triaxial geomagnetic field strength (in μT) from the mobile phone magnetometer (30 Hz)

- Latitude and longitude, and horizontal accuracy* (in meters) from the mobile phone GPS (every 5 seconds)

- Blood volume pressure (in nano Watt) from E4 photoplethysmography (PPG) sensor (64 Hz)

- Electrodermal activity (skin conductance in μS) from E4 EDA sensor (4 Hz)

- Average** heart rate values (in bps) computed in 10 seconds-span based on the BVP analysis from E4 (1 Hz)

- Peripheral skin temperature (in Celsius degrees) from E4 infrared thermopile (4 Hz)

* The estimated horizontal accuracy is defined as the radius of 68% confidence according to the API.
