Data Set Information:

该数据集包含14名年龄在66至86岁之间的健康老年人的运动数据，他们在胸骨水平的衣服上使用无电池、可穿戴的传感器进行广泛的脚本化活动。由于使用被动传感器，数据稀疏且有噪声。
参与者被分配到两个临床室（S1和S2）。S1（房间1）的设置使用房间周围的4根RFID读卡器天线（一根在天花板上，三根在墙壁上）收集数据，而S2（房间2）的设置使用3根RFID读卡器天线（两根在天花板上，一根在墙壁上）收集运动数据。
The activities performed were:
walking to the chair,
sitting on the chair,
getting off the chair,
walking to bed,
lying on bed,
getting off the bed and
walking to the door.
Hence the possible class labels assigned for every sensor observation are:
- Sitting on bed
- Sitting on chair
- Lying on bed
- Ambulating, where ambulating includes standing, walking around the room.

Attribute Information:

The content of the file is as follows:
Comma separated values (CSV) format.
Column 1: Time in seconds
Column 2: Acceleration reading in G for frontal axis
Column 3: Acceleration reading in G for vertical axis
Column 4: Acceleration reading in G for lateral axis
Column 5: Id of antenna reading sensor
Column 6: Received signal strength indicator (RSSI)
Column 7: Phase
Column 8: Frequency
Column 9: Label of activity, 1: sit on bed, 2: sit on chair, 3: lying, 4: ambulating
In addition, gender of participant is included in the last character of file name eg: d1p33F (F:female).
