Crystal-Idea System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the Crystal-Idea project, which involves designing a simple web application for a calculator app. The application will be developed for desktop platforms only, as per the updated requirements.

System Overview

Crystal-Idea is a web-based calculator application designed to provide users with basic arithmetic operations. The application will be accessible exclusively on desktop platforms, ensuring a straightforward and user-friendly interface for performing calculations.

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 input to start a new calculation.
• As a User, I should be able to view the result of my calculations immediately after input.
• As a User, I should be able to use a keyboard to input numbers and operations for calculations.

User Personas

• User: An individual who uses the calculator application for basic arithmetic operations on a desktop computer.

Core User Flows

• User opens the calculator application -> User inputs numbers and selects an operation -> User views the result -> User clears the input for a new calculation.

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)

Signature Design Concept

The Crystal-Idea calculator app will feature an interactive digital flipboard design. Each number and operation key will appear as a flipboard tile that animates with a flipping motion when pressed. This dynamic interaction will provide a tactile and engaging user experience. The flipboard effect will be implemented using framer-motion for smooth animations and transitions. The home page will greet users with a large, central flipboard display that shows the current calculation, enhancing the visual appeal and usability of the application.

Interaction Model & Motion Direction

• Interaction Model: Animated
  • The calculator will feature smooth animations for button presses and result displays, providing a polished and responsive user experience.
  • The animated flipboard effect will be the core mechanic, offering a unique interaction style for each calculation.

Non-Functional Requirements

• The application must load within 2 seconds on a standard desktop browser.
• The application should be responsive to different screen resolutions on desktop platforms.
• The application should handle up to 100 concurrent users without performance degradation.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: Not applicable for this simple calculator application
• Local orchestration: Docker

Assumptions and Constraints

• The application will only be accessible on desktop platforms.
• No mobile or tablet support is required.
• The application will not store any user data or calculations.

Glossary

• Arithmetic Operations: Basic mathematical operations including addition, subtraction, multiplication, and division.
• Flipboard: A visual effect that mimics the flipping of physical tiles, often used in digital displays for dynamic content updates.
