I fumbled this a bit because I went too technical at first, started talking about pixel arrays and then caught myself.
Start by acknowledging that your grandmother may not have a technical background, then use a relatable analogy to explain computer vision as teaching computers to 'see' and interpret images. Break down the process into simple steps: capturing images, processing them, and making decisions, and connect it to everyday examples like photo tagging or self-driving cars.
Pro tip: Show adaptability by tailoring the explanation to your grandmother's interests—if she loves gardening, compare computer vision to identifying plants or pests. This demonstrates you can communicate complex ideas to any audience, a key skill at Google.
Explain that computer vision is a field of AI that helps computers understand and interpret visual information from the world, much like how humans use their eyes and brain.
Compare computer vision to something familiar, such as teaching a child to recognize animals by showing many pictures, or using a recipe to bake a cake—following steps to achieve a result.
Describe the three main steps: input (images or video), processing (using algorithms to find patterns), and output (labels or actions). Keep it high-level and avoid jargon.
Mention applications like unlocking a phone with your face, tagging friends in photos, or self-driving cars recognizing pedestrians. Relate to her daily life if possible.
Wrap up by reiterating that computer vision helps machines 'see' and make sense of images, and ask if she has any questions to ensure clarity.
