Verdant-Design System Requirements Document

Introduction

The Verdant-Design project aims to create a simple, single-page design for a calculator. This document outlines the system requirements necessary to achieve the project's objectives.

System Overview

The Verdant-Design project focuses on developing a user-friendly, aesthetically pleasing single-page calculator application. The application will be designed to perform basic arithmetic operations and provide a seamless user experience.

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 or result to start a new calculation.
• As a User, I should be able to view the current input and result on the screen.
• As a User, I should be able to use a responsive interface that adapts to different screen sizes.

User Personas

• User: An individual who wants to perform basic arithmetic calculations using a simple and intuitive interface.

Core User Flows

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

Visuals Colors and Theme

• primary: #4CAF50 (a vibrant green reflecting the "verdant" theme)
• primary_light: #81C784 (a lighter green for hover states)
• secondary: #FF5722 (a contrasting orange for emphasis)
• accent: #FFC107 (a bright yellow for call-to-action buttons)
• highlight: #FFEB3B (a warm yellow for active indicators)
• bg: #F5F5F5 (a light grey for the background)
• surface: rgba(255, 255, 255, 0.9) (a soft white for panels)
• text: #212121 (a dark grey for primary text)
• text_muted: #757575 (a medium grey for secondary text)
• border: rgba(0, 0, 0, 0.1) (a subtle black for borders)

Signature Design Concept

The Verdant-Design calculator will feature an interactive "leaf" theme. The calculator buttons will appear as leaves that gently sway when hovered over, creating a natural and calming effect. The background will feature a subtle animation of leaves rustling in the wind, providing a dynamic and engaging user experience. This will be achieved using framer-motion for smooth animations and transitions.

Interaction Model & Motion Direction

The landing page for the Verdant-Design calculator will use an "animated" interaction model. The calculator buttons will have hover transitions and spring physics to enhance user interaction. The overall design will focus on clarity and simplicity, with minimal motion to ensure fast reading and interaction.

Non-Functional Requirements

• The application should load quickly and perform calculations without noticeable delay.
• The design should be responsive and accessible on various devices and screen sizes.
• The application should be intuitive and easy to use for all users.

Tech Stack

• Frontend: React for Web
• Backend: Not applicable for a single-page design
• Database: Not applicable for a single-page design

Assumptions and Constraints

• The project will focus solely on the design and functionality of a single-page calculator.
• No backend or database integration is required for this project.

Glossary

• Responsive Interface: An interface that adjusts smoothly to different screen sizes and orientations.
• Hover State: A visual change that occurs when a user places a cursor over an interactive element.
• Spring Physics: A type of animation that mimics natural motion, often used for smooth transitions.
