project-011f2327 System Requirements Document

Introduction (Updated)

This document outlines the system requirements for project-011f2327, focusing on the development of a simple single-page calculator application. The project aims to deliver a straightforward and efficient user experience, as per the pre-resolved design direction.

System Overview

The project-011f2327 calculator application is designed to perform basic arithmetic operations on a simple single-page layout. The application will be accessible via web browsers and will provide users with a clean and intuitive interface for performing calculations.

Functional Requirements as Story Points

• As a User, I should be able to perform addition, subtraction, multiplication, and division operations.
• 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 calculation immediately after pressing the equals button.
• As a User, I should be able to use a backspace function to correct my input before performing a calculation.

User Personas

• User: The primary user of the application who needs to perform basic arithmetic calculations quickly and efficiently.

Core User Flows

• User opens the calculator application -> enters numbers and selects an operation -> presses equals to view the result -> clears input to start a new calculation if needed.

Visuals Colors and Theme

• primary: #3498db (a calming blue for the main interface)
• primary_light: #85c1e9 (a lighter blue for hover states)
• secondary: #e74c3c (a contrasting red for error messages or alerts)
• accent: #f1c40f (a vibrant yellow for buttons and active states)
• highlight: #f39c12 (an orange for hover states and notifications)
• bg: #ecf0f1 (a light grey for the background)
• surface: rgba(255, 255, 255, 0.9) (a white for card/panel backgrounds)
• text: #2c3e50 (a dark blue for primary text)
• text_muted: #7f8c8d (a grey for secondary text)
• border: rgba(44, 62, 80, 0.2) (a subtle border color)

Signature Design Concept

The homepage of the calculator will feature a simple single-page layout with an interactive design where the calculator buttons appear to "press down" with a subtle animation when clicked, providing tactile feedback. The interface will have a minimalist aesthetic, focusing on ease of use and clarity. The calculator will have a digital display that animates numbers as they are entered, creating a dynamic and engaging user experience.

Landing Hero Motion Brief

The landing page will feature a continuous loop animation where numbers and operations appear to float into the calculator's display, demonstrating the input and calculation process. This animation will be built using motion/react to ensure smooth transitions and interactions. The animation will show numbers entering the display, the calculator performing an operation, and the result being displayed, all in a seamless loop.

Interaction Model & Motion Direction

The intended interaction model for the landing page is "animated," with moderate scroll-triggered reveals and hover transitions. The calculator buttons will have spring physics to enhance user interaction, providing a polished and responsive feel.

Non-Functional Requirements

• The application must load within 2 seconds on a standard broadband connection.
• The application should be responsive and function correctly on both desktop and mobile devices.
• The application must handle up to 100 concurrent users without performance degradation.

Tech Stack

• Frontend: React for Web
• Backend: Not applicable (client-side only application)
• Database: Not applicable (no data persistence required)

Assumptions and Constraints

• The application will be used primarily in India, and the design should consider local user preferences.
• The application will not require user authentication or data storage.

Glossary

• Single-page application: An application that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from the server.
• Responsive design: An approach to web design that makes web pages render well on a variety of devices and window or screen sizes.
