Using the Google Teachable Machine, create your own gesture recognition model. Choose three
different hand gestures (like thumbs up, wave, and peace sign). Record each gesture, train the
model, and test it to see if it recognizes your gestures correctly. Write down your observations.

In a brightly lit lab, Jamie stood before their newly built robot, eager to see it in action. They waved
their hand, and the robot whirred to life, responding perfectly. But when Jamie pointed to a nearby
object, the robot remained still. Confused, Jamie wondered if the camera was misaligned or if the
pointing gesture hadn’t been programmed correctly. With a determined sigh, Jamie set to work
troubleshooting the issue, eager to unlock the robot’s full potential.
In a cozy living room, Sam sighed in frustration as their voice control system repeatedly misunderstood
commands. Noticing their struggle, Jamie leaned in with a reassuring smile and suggested, “Let’s try
using a clearer microphone and keep the commands simple. We can also train it with your voice, so it
learns better.” With newfound hope, Sam nodded, eager to make the system work seamlessly.
