    checking their code and sensor settings. This hands-on experience boosts their understanding of
                     programming and sensors, while also developing their critical thinking and problem-solving skills!

                     Applications

                     You can make computer games that use gestures! Wave your hand to make your character run, and
                     give a thumbs-up to jump!

                     Voice Control System

                     Voice recognition technology is a fascinating part of artificial intelligence (AI) that allows machines
                     to understand and respond to spoken commands. This technology is used in various devices, from
                     smartphones  to  smart  speakers.  As  you  explore  how  voice  recognition  works,  think  about  how
                     creativity can enhance its development and functionality!

                     How Voice Recognition Works

                       Sound Waves: When you speak, your voice creates sound waves that travel through the air.

                        Microphone: A device (like a smartphone or smart speaker) has a microphone that picks up these
                        sound waves and converts them into digital signals.
                        Processing: The digital signals are then processed by AI algorithms that analyze the sounds to
                        identify words and phrases.

                        Response: Once the AI understands your command, it can perform an action, such as playing
                        music, setting reminders, or answering questions.

                                                                                                   21 st   #Technology Literacy
