emerald-start System Requirements Document

1. Introduction

The purpose of this document is to outline the system requirements for the "emerald-start" project, which aims to develop a simple single-page calculator design. This document will serve as a guide for the development and implementation of the project.

2. System Overview

The "emerald-start" project is focused on creating a user-friendly, single-page calculator application. The application will be designed to perform basic arithmetic operations and provide a seamless user experience.

3. Functional Requirements as Story Points

• 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.

4. User Personas

• User: A general user who needs to perform basic arithmetic calculations quickly and efficiently.

5. Core User Flows

• User opens the calculator -> Inputs numbers and selects an operation -> Views the result -> Clears input for a new calculation.

6. Visuals Colors and Theme

• primary: #4CAF50 (Emerald Green)
• primary_light: #81C784 (Light Emerald Green)
• secondary: #FFFFFF (White)
• accent: #FF5722 (Deep Orange)
• highlight: #FFC107 (Amber)
• bg: #F5F5F5 (Light Grey)
• surface: #FFFFFF (White)
• text: #212121 (Dark Grey)
• text_muted: #757575 (Grey)
• border: #BDBDBD (Light Grey)

7. Signature Design Concept

The "emerald-start" calculator will feature an interactive design concept where the calculator buttons animate with a subtle bounce effect when clicked, providing tactile feedback. The background will have a gradient transition from light grey to emerald green, creating a calming effect. The calculator display will have a digital-style font that mimics a classic calculator screen.

LANDING HERO MOTION BRIEF

The landing page will feature a continuous animation loop where numbers and operations appear to float and settle into the calculator display, demonstrating the input process. This will be achieved using motion/react for smooth transitions and animations. The animation will reset after a few seconds, inviting interaction.

8. Interaction Model & Motion Direction

• Intended Interaction Model: Animated
  • The calculator will have moderate hover transitions and click animations to enhance user interaction.
  • The landing page will include a continuous 2D motion loop to demonstrate the calculator's functionality.

9. Non-Functional Requirements

• The application must load quickly and perform calculations without noticeable delay.
• The design must be responsive and accessible on various devices and screen sizes.

10. Tech Stack

• Frontend: React for Web
• Backend: Not applicable (single-page application)
• Database: Not applicable (single-page application)
• AI Models: Not applicable
• AI Tools: Not applicable
• Local Orchestration: Not applicable
• Server Side Orchestration: Not applicable

11. Assumptions and Constraints

• The calculator will only perform basic arithmetic operations.
• The application will be a single-page design with no backend integration.
• The design will prioritize simplicity and ease of use.

12. Glossary

• Arithmetic Operations: Basic mathematical operations including addition, subtraction, multiplication, and division.
• Responsive Design: An approach to web design that makes web pages render well on a variety of devices and window or screen sizes.
