Orbit-Calculator System Requirements Document

1. Introduction

The Orbit-Calculator project aims to develop a simple, single-page web application that provides users with a basic calculator interface. This document outlines the system requirements for the project, ensuring a clear understanding of the functionalities, design, and technical specifications.

2. System Overview

The Orbit-Calculator is designed to offer a straightforward and user-friendly calculator interface on a single web page. The application will perform basic arithmetic operations and present a clean, intuitive layout for ease of use. The focus is on simplicity and efficiency, catering to users who need quick and reliable calculations.

3. Functional Requirements

• As a User, I should be able to perform basic arithmetic operations such as addition, subtraction, multiplication, and division.
• As a User, I should be able to clear the current calculation to start a new one.
• As a User, I should be able to view the results of my calculations immediately after input.

4. User Personas

• User: An individual who needs to perform basic arithmetic calculations quickly and efficiently on a web-based platform.

5. Core User Flows

• User opens the Orbit-Calculator web application -> User inputs numbers and selects an operation -> User views the result -> User clears the calculation to start a new one.

6. Visuals Colors and Theme

• primary: #4A90E2 (a calming blue for the main interface)
• primary_light: #A6C8FF (a lighter blue for hover states)
• secondary: #F5A623 (a warm orange for emphasis and highlights)
• accent: #50E3C2 (a vibrant teal for call-to-action buttons)
• highlight: #FFD700 (a bright gold for active indicators)
• bg: #FFFFFF (a clean white for the background)
• surface: rgba(255, 255, 255, 0.9) (a slightly translucent white for panels)
• text: #333333 (a dark grey for primary text)
• text_muted: #777777 (a softer grey for secondary text)
• border: rgba(0, 0, 0, 0.1) (a subtle grey for borders)

7. Signature Design Concept

The Orbit-Calculator will feature an interactive, minimalist design where the calculator interface appears as a floating panel on a serene, animated space-themed background. The background will subtly shift colors and display twinkling stars, creating a calming effect. Users can interact with the calculator buttons, which will have smooth animations using framer-motion for a tactile feel. The design will ensure that the focus remains on the calculator, with the background providing a soothing ambiance.

8. Interaction Model & Motion Direction

The landing page will utilize an "animated" interaction model. The calculator interface will have smooth transitions and hover effects, enhancing user interaction. The background will feature gentle animations to maintain a dynamic yet unobtrusive environment.

9. Non-Functional Requirements

• The application should load quickly and perform calculations with minimal latency.
• The user interface should be responsive and accessible across different devices and screen sizes.
• The design should adhere to web accessibility standards to ensure usability for all users.

10. Tech Stack

• Frontend: React for Web
• Backend: Not applicable (single-page application)
• Database: Not applicable (no data storage required)
• AI Models: Not applicable

11. Assumptions and Constraints

• The application will be developed as a single-page web application.
• The focus will be on basic arithmetic operations only.
• The design will prioritize simplicity and ease of use.

12. Glossary

• Arithmetic Operations: Basic mathematical operations including addition, subtraction, multiplication, and division.
• Single-Page Application (SPA): A web application that interacts with the user by dynamically rewriting the current page, rather than loading entire new pages from the server.
