Giant-Calculator System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "giant-calculator" project. This project aims to develop a simple, user-friendly calculator application that performs basic arithmetic operations within a single-page design. The focus is on delivering a clean and efficient user experience without advanced features.

System Overview

The "giant-calculator" project is designed to provide users with a straightforward tool for performing basic arithmetic calculations. The application will be accessible via a web interface, ensuring ease of use and accessibility. The system will support the following operations: addition, subtraction, multiplication, and division. The design will be minimalistic, focusing on functionality and simplicity.

Functional Requirements

• As a User, I should be able to perform addition, subtraction, multiplication, and division.
• As a User, I should be able to access the calculator on a single-page interface.

User Personas

• User: An individual who needs to perform basic arithmetic calculations quickly and efficiently without any advanced features or distractions.

Visuals Colors and Theme

The color palette for the "giant-calculator" project is designed to be simple yet visually appealing, enhancing the user experience without overwhelming the interface.

• primary: #2A9D8F (Teal)
• primary_light: #A8DADC (Light Teal)
• secondary: #E76F51 (Coral)
• accent: #F4A261 (Orange)
• highlight: #E9C46A (Gold)
• bg: #F1FAEE (Off White)
• surface: rgba(42, 157, 143, 0.8) (Teal with transparency)
• text: #264653 (Dark Blue)
• text_muted: #8D99AE (Muted Gray)
• border: rgba(233, 108, 81, 0.2) (Coral with transparency)

Signature Design Concept

The home page of the "giant-calculator" will feature an interactive, minimalist design where the calculator interface is the focal point. The calculator will have a sleek, glass-like appearance with subtle reflections and shadows, giving it a modern and sophisticated look. Users can interact with the calculator through smooth animations powered by framer-motion, where buttons gently illuminate upon hover and depress with a satisfying click animation when pressed. The background will feature a soft gradient that shifts subtly as users interact with the calculator, creating a dynamic yet calming effect. This design ensures that users are engaged and focused on the task at hand.

Interaction Model & Motion Direction

The interaction model for the "giant-calculator" landing page will be "animated." This choice ensures that the calculator interface is lively and engaging, with moderate scroll-triggered reveals and hover transitions. The use of spring physics on interactive elements will provide a polished and responsive user experience. Internal pages, if any, will maintain a "static" interaction model to prioritize clarity and speed for calculations.

Non-Functional Requirements

• The application must load within 2 seconds on standard broadband connections.
• The interface should be responsive and accessible on both desktop and mobile devices.
• The system should handle up to 100 concurrent users without performance degradation.

Tech Stack

• Frontend: React for Web
• Backend: Not applicable as the project is a single-page application with no server-side logic.
• Database: Not applicable as there is no need for data persistence.

Assumptions and Constraints

• The application will not store any user data or calculation history.
• The design will remain minimalistic, focusing solely on basic arithmetic operations.
• The application will be optimized for modern web browsers.

Glossary

• Single-page design: A web application that fits on a single page, providing a seamless user experience without page reloads.
• 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.
