# VR Charades Experiment Scripts

This directory contains scripts to run and control VR Charades experiments.

## Installation

1. Create and activate a virtual environment:
```bash
# Windows
python -m venv venv
venv\Scripts\activate

# Linux/Mac
python3 -m venv venv
source venv/bin/activate
```

2. Install Python dependencies:
```bash
pip install -r requirements.txt
```

## Files Overview

- **app.py**: Web interface for controlling the experiment and word list
- **server.py**: UDP relay server for communication between VR clients
- **control.py**: Command-line tool for setting VR client modes and server IP
- **index.html**: Web UI served by app.py
- **word-list.txt**: Default list of charade words

## Setup Instructions

### 1. Prepare Dependencies
```bash
# Activate your virtual environment first
# Windows: venv\Scripts\activate
# Linux/Mac: source venv/bin/activate

pip install -r requirements.txt
```

### 2. Network Setup
- Connect all VR headsets to the same network as the server
- Note the IP addresses of the VR headsets (you'll need these for configuration)
- **Important**: Update `server.py` lines 19-20 with your actual VR headset IPs
  ```python
  # Replace these example IPs with your actual headset IPs
  DEVICE1_ADDR = ("YOUR_PLAYER1_IP", 5001)  # e.g., ("192.168.1.100", 5001)
  DEVICE2_ADDR = ("YOUR_PLAYER2_IP", 5001)  # e.g., ("192.168.1.101", 5001)
  ```

### 3. Start the Relay Server
```bash
python server.py
```

### 4. Start the Web Interface
```bash
python -m fastapi dev app.py
```
Then navigate to `http://localhost:8000`

### 5. Configure VR Clients

Tell clients which server to connect to:
```bash
# Windows PowerShell (replace with your actual VR headset IPs)
$env:TARGET_IP="YOUR_PLAYER1_IP,YOUR_PLAYER2_IP" ; python control.py "IP:127.0.0.1"

# Linux/Mac (replace with your actual VR headset IPs)
TARGET_IP="YOUR_PLAYER1_IP,YOUR_PLAYER2_IP" python3 control.py "IP:127.0.0.1"

# Example with actual IPs:
# $env:TARGET_IP="192.168.1.100,192.168.1.101" ; python control.py "IP:127.0.0.1"
```

### 6. Set Experiment Condition

Choose one of these modes (replace YOUR_PLAYER1_IP,YOUR_PLAYER2_IP with actual IPs):
```bash
# Dynamic Face only
$env:TARGET_IP="YOUR_PLAYER1_IP,YOUR_PLAYER2_IP" ; python control.py "MODE:1;1;1;0"

# Dynamic Hands only  
$env:TARGET_IP="YOUR_PLAYER1_IP,YOUR_PLAYER2_IP" ; python control.py "MODE:0;0;0;1"

# Dynamic Hands + Face
$env:TARGET_IP="YOUR_PLAYER1_IP,YOUR_PLAYER2_IP" ; python control.py "MODE:1;1;1;1"

# Static Face only
$env:TARGET_IP="YOUR_PLAYER1_IP,YOUR_PLAYER2_IP" ; python control.py "MODE:1;0;0;0"

# Static Hands only (requires controllers)
$env:TARGET_IP="YOUR_PLAYER1_IP,YOUR_PLAYER2_IP" ; python control.py "MODE:0;0;0;1"

# Static Hands + Face (requires controllers for hands)
$env:TARGET_IP="YOUR_PLAYER1_IP,YOUR_PLAYER2_IP" ; python control.py "MODE:1;0;0;1"
```

### 7. Prepare Word List

Shuffle the word list for randomization:
```bash
# Windows PowerShell
Get-Content word-list.txt | Sort-Object {Get-Random} | Out-File word-list-shuffled.txt

# Linux/Mac
shuf word-list.txt > word-list-shuffled.txt
```

## Web Interface Usage

Once you have the web interface running at `http://localhost:8000`, follow these steps:

### Setting Up a Charades Session

1. **Configure Player IPs**
   - Enter the IP addresses of Player 1 and Player 2 VR headsets
   - These should match the IPs you used in the `control.py` commands
   - **Note**: The default placeholders (10.42.0.38, 10.42.0.100) are examples - use your actual headset IPs

2. **Prepare Word List**
   - Copy your shuffled word list from `word-list-shuffled.txt`
   - Paste it into the large text area on the right side
   - Click the **"Modify"** button to generate interactive word items

3. **Set Game Parameters**
   - **Current Player For Acting**: Select which player will be acting out the words
   - **Time (s)**: Set the time limit for each word (e.g., 30 seconds)
   - **Last Word Status**: Set to "None" for the first word

### Running the Experiment

#### Manual Mode (Individual Words)
1. Enter a word in the "Word" field
2. Select the acting player (Player 1 or Player 2)
3. Set the time limit
4. Click **"Send"** to transmit the word to the VR headsets

#### Automatic Mode (Word List)
1. After clicking "Modify" with your word list, the interface shows all words with timers
2. The system automatically:
   - Starts with the first word
   - Sends it to the selected acting player
   - Counts down the timer for each word
   - Moves to the next word when time expires or word is marked correct

3. **During the session**:
   - **Mark words correct**: Hover over a word and check the checkbox if guessed correctly
   - **Timer display**: Shows remaining time for current word
   - **Visual indicators**: 
     - ▶ = Current word being acted
     - ✅ = Correctly guessed word
     - ❌ = Time expired / incorrect word

4. **Stop the session**: Click **"Stop"** to end early

### Exporting Results

1. After completing the word list, click **"Save as CSV"**
2. This downloads a CSV file with:
   - Word name
   - Whether it was guessed correctly (true/false)
   - Time remaining when completed
