nova-system System Requirements Document

Introduction

The nova-system project is focused on developing a simple, single-page design for a calculator application. This document outlines the system requirements to guide the development process.

System Overview

The nova-system is a straightforward calculator application designed to perform basic arithmetic operations. The application will be a single-page web application, ensuring ease of use and accessibility.

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 pressing the equals button.
• As a User, I should be able to input numbers using an on-screen keypad.

User Personas

• User: An individual looking to perform basic arithmetic calculations quickly and efficiently using a web-based calculator.

Core User Flows

• User opens the calculator application -> User inputs numbers and selects operations -> User presses equals to view the result -> User clears input to start a new calculation.

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 vibrant orange for emphasis and active states)
• accent: #50E3C2 (a contrasting green for call-to-action buttons)
• highlight: #F8E71C (a bright yellow for notifications and alerts)
• bg: #FFFFFF (a clean white for the background)
• surface: rgba(255, 255, 255, 0.9) (a subtle 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 light grey for borders)

Signature Design Concept

The homepage of the nova-system calculator will feature an interactive, minimalist design where the calculator keypad and display are the focal points. The design will include a subtle animation where buttons gently expand when hovered over, providing a tactile feel. The background will have a soft gradient that shifts slightly as the user interacts with the calculator, creating a dynamic yet unobtrusive experience. This will be implemented using framer-motion for smooth animations and transitions.

Interaction Model & Motion Direction

The interaction model for the nova-system calculator will be "animated". The single-page design will feature hover transitions and smooth animations for button presses, enhancing the user experience without overwhelming the simplicity of the application.

Non-Functional Requirements

• The application should load quickly and be responsive on all modern web browsers.
• The design should be intuitive and require no learning curve for users.
• The application should be accessible and usable on both desktop and mobile devices.

Tech Stack

• Frontend: React for Web
• Backend: Not applicable (single-page application)
• Database: Not applicable (single-page application)

Assumptions and Constraints

• The application will not store any user data or history.
• The calculator will only perform basic arithmetic operations.
• The design will remain simple and uncluttered, focusing on usability.

Glossary

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