Ocean-Hello System Requirements Document

1. Introduction

The Ocean-Hello project is designed to provide a simple and efficient way to greet users with a three-word message. This document outlines the system requirements for implementing this functionality.

2. System Overview

Ocean-Hello is a lightweight application focused on delivering a concise, three-word greeting to users. The system is designed to be intuitive and user-friendly, ensuring that users receive a warm welcome in a minimalistic format.

3. Functional Requirements as Story Points

• As a User, I should be able to receive a greeting that consists of exactly three words.

4. User Personas

• User: An individual who interacts with the Ocean-Hello application to receive a greeting.

5. Core User Flows

• User accesses the application -> User receives a three-word greeting.

6. Visuals Colors and Theme

• primary: #1E90FF (Dodger Blue)
• primary_light: #63B8FF (Light Sky Blue)
• secondary: #FF6347 (Tomato)
• accent: #32CD32 (Lime Green)
• highlight: #FFD700 (Gold)
• bg: #F0F8FF (Alice Blue)
• surface: rgba(255, 255, 255, 0.9)
• text: #000000 (Black)
• text_muted: #696969 (Dim Gray)
• border: rgba(0, 0, 0, 0.1)

7. Signature Design Concept

The Ocean-Hello homepage will feature an interactive ocean wave animation using @react-three/fiber and @react-three/drei. As users move their cursor, the waves will gently ripple, creating a soothing and dynamic background. The three-word greeting will appear as if written in the sand, with each word revealed sequentially as the waves recede. This engaging interaction will captivate users and provide a memorable first impression.

8. Interaction Model & Motion Direction

• Interaction Model: Parallax
• The homepage will utilize a parallax effect, with layered ocean waves moving at different speeds to create depth. The greeting text will smoothly transition into view as users scroll, enhancing the immersive experience.

9. Non-Functional Requirements

• The system should load the greeting within 2 seconds.
• The application must be accessible and responsive across all major devices and browsers.

10. Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: Not applicable for this simple greeting application

11. Assumptions and Constraints

• The greeting will always be in English.
• The application will not require user authentication.

12. Glossary

• Greeting: A message that welcomes the user, consisting of three words.
• Parallax: A scrolling technique that creates an illusion of depth by moving background images slower than foreground images.
