Dataset

Environment

• At most one person in the room
• To get closer to the real environment, there is at least one heat source in the room.
• Two or three persons are acting in a sequence (No frames contain more than two persons at the same time.)

Indoor scenes

Actions

• "sit"
• "stand"
• "walk"
• "fall"
• "lie"
• "standup"
• "sitdown"
• "lying"

Dataset file format

The data file name format as following:

<date>_<sensor model>_<indoor scene>_<lighting>_<heat source>.csv

E.g., 20200623_mlx90640_01_natural_none.csv

Sensor model

It's correspond to the sensors in the "Condition" part above, such as "mlx90640", "htpa32-01", "camerav2".

Lighting

• "light" means that data is collected when fluorescent lamp is turned on.
• "dark" means that data is collected at night without any light source.
• "natural" means that data is collected with natural lighting.

Heat source

There are five type of heat source.

• "none": no any heat source.
• ""
