Smart Home Devices 

1. • Photography: Effective for capturing images of smart devices like thermostats, lights, or security systems.

   • Video/Audio: Can be used to demonstrate how these devices respond to voice commands or interact with users.

2. Voice-Activated Systems

   • Audio Recording: Ideal for documenting interactions with systems like Siri, Alexa, or Google Assistant.

   • Video: Can show the context in which voice-activated systems are used, such as in cars, smartphones, or smart speakers.

3. Social Media Algorithms

   • Screenshots/Screen Recordings: Since these algorithms are mostly digital and not physical, capturing screen activity could be more effective than traditional photography.

   • Presentation Slides: Students can use slides to explain how these algorithms work, as the functionality might not be easily captured through images or videos alone.

4. Autonomous Vehicles 

   • Photography/Video: Great for capturing self-driving cars in action or stationary. Videos can particularly showcase the movement and interaction of these vehicles with their environment.
