WiFi (CSI and RSSI) Data of Six Basic Knife Activities for Cooking (chopping, cubing, French cutting, julienning, mincing, and slicing)

To gather the dataset, we asked two participants to perform six basic knife activities. The layout of the system experiment is provided in Fig. 4. As it illustrates, we put the receiver on the right side and the ESP32 transceiver on the left side of the performing area. The performing area is a cutting board (30 x 46 cm) in this experiment. Each participant performs each activity five times in the performing area. The data is recorded using a customized version of ESP32-CSI-tool [38] on the laptop that helps us to record and save each data in a separate file. After recording all 60 data entries, we used a python code to extract the clean data from all generated text by the tool. The clean data is stored in a database and creates the dataset.

为收集该数据集，我们邀请了两位参与者执行六项基本刀具操作。系统实验的布局如图4所示。如图所述，我们将接收器放置在执行区域的右侧，而ESP32收发器则位于左侧。在本实验中，执行区域为一块切割板（尺寸为30 x 46厘米）。每位参与者均在执行区域内重复每项操作五次。数据记录采用ESP32-CSI-tool [38]的定制版本，该工具安装于笔记本电脑上，用于记录并保存每条数据至独立文件中。记录完所有60条数据条目后，我们利用Python代码从由该工具生成的所有文本中提取干净数据。这些干净数据被存储于数据库中，并据此构建了数据集。
