Observations

In the hand gesture activity, students will observe how the machine learning model trained to
recognize different hand gestures works. When a gesture is performed, the model correctly
identifies it and displays the corresponding icon on the micro:bit’s LED screen. Students will notice
the accuracy of gesture recognition and how it affects the micro:bit display, demonstrating real-
time integration between AI models and hardware systems. This provides a hands-on understanding
of AI-driven interfaces and physical computing.

Applications of Hand Gesture Recognition

Hand gesture recognition has many real-world applications. Here are a few examples:

Gaming: Players can use hand gestures to control characters or actions in video games, providing
a more interactive experience.
Smart Homes: You could use gestures to control devices like lights, TVs, or music players without
touching anything.

Accessibility: People with physical disabilities can use hand gestures to interact with devices
that might otherwise be difficult to control.

Robotics: Robots can be controlled with hand gestures, making them more interactive and easier
to operate in certain situations.

Voice Recognition Systems with AI

Voice recognition systems, combined with AI (Artificial Intelligence), have become a significant part
of modern technology. Devices like smart speakers, virtual assistants (like Siri or Alexa), and even
apps on our phones use voice recognition to understand and respond to our spoken commands.

What is Voice Recognition?

Voice recognition, also known as speech recognition, is the
technology that allows machines to understand and process the
words we say. It enables computers and devices to “listen” to
human speech, recognize specific words or phrases, and then carry
out tasks based on the command.

For example, when you say, “Play my favourite song,” the voice recognition system understands
what you’ve said and sends a command to play music. It’s like teaching a machine to understand our
language so that it can respond to our needs.

How Does Voice Recognition Work?

Voice recognition works in several steps. Here’s a simple breakdown of how it processes our speech:

1. Capturing the Voice: First, the device uses a microphone to capture the sound of your voice. It
picks up the audio and sends it to the system for processing.
