- **Dataset Summary:**
  The WiGesture dataset contains synchronized Channel State Information (CSI), Received Signal Strength Indicator (RSSI), and timestamp data collected using ESP32-S3 devices for WiFi-based human gesture recognition and people identification in a meeting room scenario. The dataset is divided into dynamic gestures (e.g., applause, waving) and static digital gestures (numbers 1–9), performed by eight individuals.

- **Tasks:** Gesture Recognition, People Identification, Cross-Domain Tasks.

## Dataset Structure

### Data Instances

Each instance is a `.csv` file representing a 60-second sample with the following columns:  

- **seq**: Row number of the entry.  
- **timestamp**: UTC+8 time of data collection.  
- **local_timestamp**: ESP32 local time.  
- **rssi**: Received Signal Strength Indicator.  
- **data**: CSI data with 104 numbers representing 52 subcarriers, where each subcarrier's complex CSI value is computed as `a[2i] + a[2i+1]j`.  
- **Other columns**: Additional ESP32 device information (e.g., MAC, MCS details).

### Data Fields

| Field Name      | Description                                                  |
| --------------- | ------------------------------------------------------------ |
| seq             | Row number of the entry                                      |
| timestamp       | UTC+8 time of data collection                                |
| local_timestamp | ESP32 local time                                             |
| rssi            | Received Signal Strength Indicator                           |
| data            | CSI data (104 numbers, representing 52 subcarriers as complex values) |
| Other columns   | Additional ESP32 metadata (e.g., MAC address, MCS details)   |

### Data Splits

The dataset is organized into two main directories:  

- **Dynamic**: Contains dynamic gestures (applause, circleclockwise, frontandafter, leftandright, upanddown, waveright) for 8 individuals (ID1–ID8).  
- **Static**: Contains static digital gestures (Gesture1–Gesture9, representing numbers 1–9) for 8 individuals (ID1–ID8).

Each directory is structured by person ID, with `.csv` files named after the gesture performed.

## Dataset Creation

### Curation Rationale

The dataset was created to facilitate research on WiFi-based gesture recognition and people identification using low-cost ESP32-S3 devices, enabling applications in human-computer interaction and smart environments.

### Source Data

- **Initial Data Collection:**
  Data was collected in an indoor meeting room with a single transmitter and multiple receivers using ESP32-S3 devices. The setup included:  
  - **Frequency Band:** 2.4 GHz  
  - **Bandwidth:** 20 MHz (52 subcarriers)  
  - **Protocol:** 802.11n  
  - **Waveform:** OFDM  
  - **Sampling Rate:** ~100 Hz  
  - **Antenna Configuration:** 1 antenna per device  
  - **Environment:** Indoor with walls and a soft pad to prevent volunteer injuries.
- **Who are the source data producers?**
  The data was collected by researchers, with volunteers performing gestures in a controlled meeting room environment.

### Annotations

- **Annotation Process:**
  Each `.csv` file is labeled with the gesture type (via filename) and person ID (via directory structure). No additional manual annotations were provided.  
- **Who are the annotators?**
  The dataset creators labeled the data based on the experimental setup.

### Personal and Sensitive Information

The dataset includes person IDs (ID1–ID8) but does not contain personally identifiable information such as names or biometric data beyond gesture and CSI patterns.
