# HRIStudio
# A Web-Based Wizard-of-Oz Platform for Collaborative and Reproducible Human-Robot Interaction Research
HRIStudio is a comprehensive web-based platform for managing Wizard of Oz (WoZ) studies in Human-Robot Interaction research. It provides researchers with standardized tools for designing experiments, executing trials, and analyzing data while ensuring reproducibility and scientific rigor.
A markdown-based conference presentation using Marp with a custom mono/minimal theme, featuring ASCII diagrams and professional formatting.
## Features
## Quick Start
- **Visual Experiment Designer**: Drag-and-drop interface for creating complex interaction scenarios
- **Real-time Trial Control**: Live robot control with responsive wizard interface during experiments
- **Hierarchical Study Structure**: Organized workflow from Study → Experiment → Trial → Step → Action
- **Multi-modal Data Capture**: Synchronized recording of video, audio, logs, and sensor data
- **Role-based Access Control**: Four distinct roles (Administrator, Researcher, Wizard, Observer)
- **Robot Platform Integration**: Support for multiple robot platforms via RESTful APIs, ROS, and custom plugins
- **Collaborative Research**: Team management with secure data sharing and role-based permissions
## Tech Stack
- **Framework**: [Next.js 15](https://nextjs.org) with App Router
- **Authentication**: [NextAuth.js v5](https://next-auth.js.org)
- **Database**: [PostgreSQL](https://postgresql.org) with [Drizzle ORM](https://orm.drizzle.team)
- **Storage**: [MinIO](https://min.io) (S3-compatible) for media files
- **API**: [tRPC](https://trpc.io) for type-safe client-server communication
- **UI**: [Tailwind CSS](https://tailwindcss.com) with [shadcn/ui](https://ui.shadcn.com) and [Radix UI](https://radix-ui.com)
- **Package Manager**: [Bun](https://bun.sh) (exclusively)
## Getting Started
### Prerequisites
- [Bun](https://bun.sh) (latest version)
- [PostgreSQL](https://postgresql.org) (14+)
- [Docker](https://docker.com) (optional, for containerized deployment)
### Installation
1. Clone the repository:
```bash
git clone https://github.com/your-org/hristudio.git
cd hristudio
```
2. Install dependencies:
```bash
# Install dependencies
bun install
# OR
npm install
# Start live preview (recommended for editing)
./start-presentation.sh preview
# Build PDF for conference submission
./start-presentation.sh pdf
```
3. Set up environment variables:
```bash
cp .env.example .env
# Edit .env with your database credentials and other settings
```
## Available Scripts
4. Start the database (using Docker):
```bash
bun run docker:up
```
- `bun run preview` - Live preview with auto-reload
- `bun run watch` - Watch mode with browser preview
- `bun run build:pdf` - Generate PDF for conference
- `bun run build:html` - Generate HTML version
- `bun run build:pptx` - Generate PowerPoint format
- `bun run build:all` - Build all formats
- `bun run serve` - Start development server
5. Push the database schema:
```bash
bun run db:push
```
## Files
6. Start the development server:
```bash
bun dev
```
- `hristudio-presentation.md` - Main presentation content
- `start-presentation.sh` - Quick start helper script
- `package.json` - Dependencies and scripts
Open [http://localhost:3000](http://localhost:3000) in your browser.
## Design System
## Development Commands
The presentation uses a mono/minimal aesthetic with:
| Command | Description |
|---------|-------------|
| `bun dev` | Start development server |
| `bun build` | Build for production |
| `bun start` | Start production server |
| `bun typecheck` | Run TypeScript checks |
| `bun lint` | Run ESLint |
| `bun lint --fix` | Fix ESLint issues |
| `bun test` | Run tests |
| `bun db:generate` | Generate database schema |
| `bun db:migrate` | Run database migrations |
| `bun db:push` | Push schema changes |
| `bun db:studio` | Open database studio |
- **Font**: JetBrains Mono (Geist Mono fallback)
- **Colors**: Matching HRIStudio's oklch color scheme
- **Layout**: Clean, spacious design with no unnecessary elements
- **Typography**: Consistent hierarchy with proper spacing

1. **Edit**: Modify `hristudio-presentation.md` in your editor
2. **Preview**: Run `./start-presentation.sh preview` for live reload
3. **Build**: Generate final PDF with `./start-presentation.sh pdf`
4. **Version Control**: All files are text-based and git-friendly
## Architecture
## VS Code Integration
HRIStudio follows a three-layer architecture:
Install "Marp for VS Code" extension for:
- Live preview in editor
- Syntax highlighting
- Immediate feedback while editing
1. **User Interface Layer**: Browser-based interfaces for experiment design, wizard control, and data analysis
2. **Data Management Layer**: PostgreSQL database with role-based access control and MinIO for media storage
3. **Robot Integration Layer**: Platform-agnostic communication supporting RESTful APIs, ROS, and custom plugins
## Conference Requirements
## Key Concepts
The generated PDF meets standard conference requirements:
- 16:9 aspect ratio for projectors
- High-quality embedded fonts
- Professional typography
- Consistent with academic presentation standards
### Hierarchical Study Structure
## Customization
- **Study**: Top-level container for a research project
- **Experiment**: Parameterized template specifying experimental protocol
- **Trial**: Executable instance with specific participant and conditions
- **Step**: Distinct phase containing wizard or robot instructions
- **Action**: Specific atomic task (speech, movement, input gathering, etc.)
- Edit content in `hristudio-presentation.md`
- Modify colors/fonts in the `<style>` section
- Add new slides by inserting `---` separators
- Use custom CSS classes for special formatting
### User Roles
- **Administrator**: Full system access and user management
- **Researcher**: Study creation, experiment design, data analysis
- **Wizard**: Trial execution and robot control
- **Observer**: Read-only access to trials and data
