teal-start System Requirements Document

1. Introduction

The purpose of this document is to outline the system requirements for the "teal-start" project, which aims to develop a simple single-page calculator design. This document will serve as a guide for the development and design teams to ensure that the final product meets the specified requirements.

2. System Overview

The "teal-start" project is focused on creating a user-friendly, single-page calculator application. The application will be designed to perform basic arithmetic operations and provide a clean, intuitive interface for users.

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 clearly on the calculator interface.

4. User Personas

• User: An individual looking to perform basic arithmetic calculations quickly and efficiently on a single-page application.

5. Core User Flows

• User opens the calculator application -> User inputs numbers and selects an operation -> User receives the result -> User can clear the input/result to perform a new calculation.

6. Visuals Colors and Theme

• primary: #008080 (Teal)
• primary_light: #66b2b2 (Light Teal)
• secondary: #f0f0f0 (Light Gray)
• accent: #ffcc00 (Yellow)
• highlight: #ff6600 (Orange)
• bg: #ffffff (White)
• surface: #e0e0e0 (Gray)
• text: #000000 (Black)
• text_muted: #666666 (Dark Gray)
• border: #cccccc (Light Gray)

7. Signature Design Concept

The homepage of the calculator will feature an interactive design where the buttons appear to "press" down when clicked, providing a tactile feedback experience. The calculator will have a sleek, modern look with rounded buttons and a digital display that mimics a real calculator screen. The interface will be responsive, adjusting to different screen sizes while maintaining usability.

LANDING HERO MOTION BRIEF

The landing page will feature a continuous animation where numbers and operations flow into the calculator display, demonstrating the input and calculation process. This animation will loop every 10 seconds, showing a sequence of numbers being entered, calculated, and the result displayed. The animation will be created using motion/react for smooth transitions and interactions.

8. Interaction Model & Motion Direction

• Interaction Model: Animated
  • The calculator will feature smooth transitions and animations for button presses and result displays.
  • Hover transitions and spring physics will be applied to interactive elements to enhance user experience.

9. Non-Functional Requirements

• The application must 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.

10. Tech Stack

• Frontend: React for Web

11. Assumptions and Constraints

• The calculator will only perform basic arithmetic operations.
• The application will be a single-page design, focusing on simplicity and ease of use.

12. Glossary

• Arithmetic Operations: Basic mathematical operations including addition, subtraction, multiplication, and division.
• Responsive Design: A design approach that ensures the application works well on various devices and screen sizes.
• Single-Page Application: An application that operates within a single web page, providing a seamless user experience without page reloads.
