In the Kemu world, a Thing is a mini-program designed to capture or process data and perform a task. You can think of these "Things" as equivalent to Apps found on your mobile phone.
Some example Things are:
Webcam: allows you to capture live images from your webcam.
Microphone: captures live audio from your microphone.
There are also Things that only process information, for instance:
Image Trigger: Detects changes in images.
Image Classifier: Uses machine learning to detect objects in images.
Things can be linked together to interact with each other. For example, you could connect a Microphone Thing to a Spectrogram Thing to visualize the frequencies of your audio in real-time.
