Overview of How the Death Calculator Works
The Death Calculator is designed to estimate life expectancy based on user-inputted factors and provide interactive visualizations and information about remaining lifespan.
Form Submission Handling:
When the user submits the form with their name, date of birth (DOB), gender, lifestyle habits (smoking, exercise, diet, alcohol consumption), and living area, the JavaScript code captures these inputs.
Calculation of Life Expectancy:
Using the moment.js library, the calculator computes the user's current age and total days lived since their DOB.
Factors such as gender, smoking habits, exercise frequency, diet quality, alcohol consumption, and living area are taken into account to adjust the baseline life expectancy (set at 80 years in this example).
Displaying Results:
The calculated life expectancy, along with various informative details, is displayed dynamically in the user interface.
Information includes the user's birth date, current age, days lived, approximate seconds lived, and years remaining based on adjusted life expectancy.
Motivational and inspirational quotes are also included to encourage the user.
Visual Representation (Chart.js):
A doughnut chart is generated using Chart.js to visually represent the user's lifespan.
The chart displays two segments: years lived and years remaining, with corresponding colors and labels.
It provides a quick and intuitive visualization of how much of life has been lived and how much remains.
Real-Time Countdown:
A countdown timer dynamically calculates and displays the remaining years, days, hours, minutes, and seconds until the estimated death date.
It updates every second to reflect real-time changes based on the user's current age and adjusted life expectancy.
Speech Synthesis:
A feature allows the calculator to speak the calculated results aloud using the browser's SpeechSynthesis API.
When initiated, the calculator reads out details like name, birth date, age, days lived, remaining years, and motivational quotes.
A "Stop Speaking" button allows users to interrupt or stop the speech synthesis at any time.
User Experience and Accessibility:
The calculator enhances user experience with interactive elements like dynamic charts, real-time countdowns, and spoken output.
It promotes accessibility through speech synthesis, making the information accessible to users with visual impairments or those who prefer auditory feedback.
Overall, the Death Calculator provides a personalized and interactive experience by combining data analysis, visualization, real-time updates, and accessibility features to engage users in understanding and reflecting on their estimated lifespan based on various lifestyle choices and demographic factors.
