Project Title: “Future Vision: Screen Capture Insights with ‘Next’”

Description:

In this project, we merge the thrilling and predictive elements of Nicolas Cage’s 2007 film Next with the capabilities of the Screen Capture API. Next follows Cris Johnson, a man with the ability to see two minutes into the future. Similarly, this project will enable users to capture and analyze their screen activities, providing insights and predictions based on the captured data.

Features:

1. Screen Capture: Use the Screen Capture API to allow users to capture their screen activity.
2. Real-Time Analysis: Implement real-time analysis of the captured screen data to provide insights and predictive suggestions.
3. User-Friendly Interface: Create an intuitive interface where users can start and stop screen capture, view captured data, and receive insights.

Starting Code:

Beginner Hints:

• Create a single index.html file.
• Copy the full HTML code block into that file.
• Open index.html in your browser. If something doesn’t work, try a local server like python -m http.server.
• Open DevTools Console to spot errors and typos quickly.

Here’s a basic setup to get you started. This includes the initial HTML, CSS, and JavaScript to integrate the Screen Capture API and create a simple screen capture application.
