Exercises — Session 5 🟢

“AI that sees, hears and creates”

Program : Applied AI — Beginner Level · Instructor: Yann Isola Material : paper + pencil. Access to a generative AI tool for exercise 3 (“screenless” version provided).

Exercise 1 — Describe the image for a blind AI 👁

Duration: 15 min · In pairs

The idea

An image generation AI does not “see” what you have in mind: it only knows the words of your description (the prompt ). This exercise puts you in his shoes…and teaches you how to write good descriptions.

Unrolled

Step 1 (5 mins): Player A secretly chooses a simple image (provided by the instructor, or an image of his choice: a landscape, a scene, an animal in a setting). Player B does not see it.

Step 2 (5 mins): Player A describes the image only with words , as if he were writing a prompt for an AI. Player B draws what he understands (a quick, ugly drawing is perfect!). Forbidden to look at B's drawing along the way — an AI doesn't get a second chance either.

Step 3 (5 mins): Compare the drawing and the original image. Discuss:

What to remember

A good description for precise AI: the subject (What ?), the action (what does he do?), the decor (Or ?), style and atmosphere (realistic? cartoon? day? night?). The more precise it is, the more the result corresponds to what you imagine. This is exactly the job of “prompting well”.

Exercise 2 — The deepfake detective challenge 🕵

Duration: 15 min · In small groups (3-4)

The idea

Learn to spot content created by AI — and above all, adopt the right reflexes even when the image is perfect .

Part A — The hunt for clues (5 min)

The instructor projects a series of images (or use the detective game of the session web page). For each image, your group votes: REAL Or AI ?

Note for each image the clue that made your decision:

Picture Voting (Real / AI) Decisive clue
1
2
3
4
5
6

Part B — The detective’s checklist (5 min)

As a group, classify these clues into two families: 👁 visual cues (in the picture) and 🧠 context clues (around the image):

strange hands · anonymous account publishing · illegible text in the background · no other source mentions it · inconsistent reflections in the glasses · the image provokes a very strong emotion · strange teeth or ears · publication that is “too good” (election, scandal, etc.) · blurred and distorted background · known and reliable media

Trick question: In a year, will visual cues still work as well? Which ones will remain valid forever? ⚠

Part C — The scenario (5 min)

Your group receives this scenario:

You receive a video on your phone where a celebrity announces something incredible. A friend urges you: “Share, quickly!! »

Write in 3 lines what you are doing, in order, Before to share (or not).

What to remember

The visual defects of deepfakes disappear as AI advances ⚠. Reflexes that remain valid forever: check the source, cross-check information, be wary of strong emotions . A modern detective checks around of the image as much as In the image.

Exercise 3 — My mini AI studio 🎨🎵

Duration: 25-30 min · Alone or in pairs · Creative project

The idea

You become a mini-creation studio: you will produce a small work by combining at least two contents created (or designed) with AI, then present it.

Assignment

Choose a theme from (or invent your own, validated by the instructor):

Version A — With access to AI tools ⚠

  1. Picture : write a neat prompt (use the grid from exercise 1) and generate an image with the tool indicated by the instructor. You have the right to 3 attempts maximum — improve your prompt between each test and keep track of your 3 versions.
  2. Text : ask a text AI for a slogan, mini-poem or 3-sentence synopsis to accompany your image.
  3. Bonus sound: if a music tool is available ⚠, describe the background music of your work (style, instruments, tempo) and generate 30 seconds.
  4. Assemble the whole thing (one page, one slide or simply side by side).

Version B — Without screen (just as valid!)

  1. Picture : write the perfect prompt for your image (5 lines max) and draw quickly what you think the AI ​​would produce — including its likely errors (hands? text? details?).
  2. Text : write the slogan yourself, then write the prompt you would have given the AI ​​to get it.
  3. Her : describe in 3 lines the music you would ask of a musical AI (style, instruments, atmosphere, tempo).

Presentation (1 minute per studio)

Imposed structure:

  1. What I asked (my prompt)
  2. What I got (to show)
  3. What I had to correct (the gap between the idea and the result)

Golden rules of the studio 📜

What to remember

Creating with AI is not about pressing a button: it’s describe precisely, evaluate the result, correct, start again . The idea, the taste and the responsibility remain human.
