wooden-start System Requirements Document

1. Introduction

The "wooden-start" project aims to develop a simple, single-page calculator design. This document outlines the system requirements for the project, ensuring that all necessary functionalities and design elements are captured and implemented effectively.

2. System Overview

The "wooden-start" project will deliver a basic calculator application that operates on a single web page. The calculator will perform standard arithmetic operations and provide a user-friendly interface suitable for a broad audience.

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 or result to start a new calculation.
• As a User, I should be able to view the current input and result on the calculator display.
• As a User, I should be able to use a decimal point for fractional calculations.
• As a User, I should be able to use the calculator on both desktop and mobile devices.

4. User Personas

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

5. Core User Flows

1. User opens the calculator page.
2. User inputs numbers and selects an arithmetic operation.
3. User views the result on the display.
4. User clears the input/result to perform another calculation.

6. Visuals Colors and Theme

[Default — not specified by user]

• primary: #3498db (a calming blue for the main interface)
• primary_light: #85c1e9 (a lighter blue for hover states)
• secondary: #2ecc71 (a green for secondary actions)
• accent: #e74c3c (a red for error states or clear button)
• highlight: #f1c40f (a yellow for active indicators)
• bg: #ecf0f1 (a light grey for the background)
• surface: #ffffff (white for the calculator body)
• text: #2c3e50 (dark blue for primary text)
• text_muted: #95a5a6 (grey for secondary text)
• border: #bdc3c7 (light grey for borders)

7. Signature Design Concept

The calculator will feature an interactive, tactile design where each button appears to press down when clicked, providing a physical feedback illusion. The interface will resemble a wooden desk with a calculator sitting on it, giving a warm, inviting feel. The buttons will have a subtle shadow effect that enhances the 3D illusion, making the interaction feel more realistic.

Landing Hero Motion Brief

The landing page will feature a continuous animation of the calculator buttons being pressed in a sequence, demonstrating its functionality. This animation will loop every 10 seconds, showing different arithmetic operations being performed. The animation will be built using motion/react for smooth transitions and interactions. The first frame will display a clean, inviting calculator ready for user interaction, with unobstructed copy and CTAs.

8. Interaction Model & Motion Direction

• Interaction Model: Animated
  • The calculator will feature moderate hover transitions and spring physics on button interactions to enhance user experience.
• Motion Direction: The landing page will have a continuous 2D motion loop showcasing the calculator's functionality.

9. Non-Functional Requirements

• The calculator must load quickly and be responsive on both desktop and mobile devices.
• The application should be accessible, adhering to WCAG 2.1 standards.

10. Tech Stack

[Default — not specified by user]

• Frontend: React for Web
• Backend: None required for a single-page application
• Database: None required for a single-page application

11. Assumptions and Constraints

• The calculator will only perform basic arithmetic operations.
• The application will be a single-page design without the need for backend integration.
• The design will be responsive and accessible across different devices and screen sizes.

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.
• WCAG 2.1: Web Content Accessibility Guidelines, a set of recommendations for making web content more accessible.
