Dynamically Generated Closed Captioning Cloud

Dynamically Generated Closed Captioning Cloud

The makers of the Video Experimenter Shield for Arduino have used their product to create an instantly updating word cloud from over-the-air television closed captioning data. The NTSC video is passed through the shield and the Arduino sends the closed captioning text to the computer via serial. The cloud is generated by a Processing sketch, which makes words larger if they’re spoken more frequently.
