Lifelike AI robots: What is the Uncanny Valley?

Why?

<!-- /wp:heading -->

This lesson on the Uncanny Valley introduces students to critical concepts in robotics and artificial intelligence, focusing on human responses to humanoid robots that resemble humans in appearance and behavior. By exploring emotional reactions through empathy maps and discussions, students gain insights into human psychology, the importance of design in technology, and ethical considerations in AI development. Engaging with this topic encourages empathy, ethical reasoning, and technological literacy, equipping students with the skills to navigate and shape the future landscape of AI and robotics.

Materials Needed			Time needed
Printouts of the scenario cards and empathy map handout for each group			Approximately 45 to 60 minutes
Objectives
- Students will be able to identify the characteristics that contribute to the Uncanny Valley effect in humanoid robots and articulate why these features might be unsettling.

• Students will be able to analyze different humanoid robots' appearances and behaviors using empathy maps to determine how human-likeness affects human perception and emotional response.
• Students will be able to compare and contrast emotional reactions to robots with varying degrees of human-like features to explore personal and collective thresholds within the Uncanny Valley. | | | | | | | Key Concepts & Vocabulary  | | | | | | | Uncanny Valley: A theory in robotics and animation suggesting that humanoid objects which imperfectly resemble actual human beings elicit feelings of eeriness and discomfort among some observers.Humanoid Robot: A robot with its body shape built to resemble the human body, typically designed to imitate human gestures and interactions.Empathy Map: A visual tool used to articulate what we understand about a particular user’s needs, desires, and behaviors. It helps creators empathize with users and can include categories like what the user says, thinks, does, and feels. | | | | | | | Lesson   | | | | | | | 1. Introduce the concept of the Uncanny Valley and discuss how it might affect perceptions of AI. (The Uncanny Valley is a concept in robotics and animation describing a phenomenon where humanoid objects that closely resemble humans provoke eerie or unsettling feelings among human observers. This reaction intensifies as the humanoid’s appearance and behavior become almost, but not perfectly, lifelike. People actually prefer less-human looking robots.)

2. Show images or videos of robots that seem to have intelligence and look very human. Ask why it is that videos like this are scary to people.
3. Divide the class into small groups and assign each group a different scenario. Scenarios could vary from highly mechanical robots to nearly human-like AIs, with incremental adjustments in appearance or behavior.
4. Each scenario (see end of lesson plan for scenarios) will describe a theoretical interaction with the AI, emphasizing its physical appearance and behavior.
5. Briefly explain what an empathy map is: a tool used to articulate what we understand about a particular person or character, including what they are seeing, thinking, and feeling.
6. Groups will create empathy maps for their assigned AI character. They should consider and note down what humans might think, feel, hear, and see when interacting with the AI.Encourage creativity: they can draw the AI’s expressions, write down imagined quotes from people interacting with the AI, and map out emotional reactions.
7. Each group presents their empathy map and explains the rationale behind their insights into human reactions to their AI.
8. Discuss as a class how the level of human likeness might influence human reactions, referring specifically to the Uncanny Valley theory. | | | | | | | Discussion Questions | | | | | | | - Why might people feel uneasy around robots that look almost human but aren't perfect? What triggers these feelings?

• How did your feelings change between interacting with very robotic AIs and almost-human AIs? Explain using your empathy map.
• What ethical issues could arise from creating robots that look and act almost human? Discuss some potential problems.
• Do you think robots should be made to look like humans? Why or why not?
• Can you think of any scenarios where the Uncanny Valley effect might be beneficial? How so?
• How does the concept of the Uncanny Valley impact your thoughts on the future of AI and robotics?
• What could be done to make robots less unsettling to people who experience the Uncanny Valley effect? | | | | | | | Supplemental Activity Ideas  | | | | | | | Role-Play: Organize a role-playing activity where students act out scenes using characters that are robots with varying degrees of human-likeness. Reflect on how portraying different types of characters affects their performance and audience reactions.Creative Writing with AI: Students write a short story (possibly with the help of an AI chatbot) in which characters traverse the Uncanny Valley, reflecting on the differences in characters as they cross the point where they may be seen as more or less human.Robot Design Challenge: Students design their own robot in groups, choosing features that would either amplify or minimize the Uncanny Valley effect. They can create models using craft materials and present their designs to the class, explaining their choices based on scientific principles of human-robot interaction.Historical Comparison: Students research and present on various cultural attitudes towards human-like figures in history (such as automatons, golems, and other automata) and compare these historical perspectives to modern reactions to humanoid robots.Empathy and Ethics Workshop: Run a workshop where students discuss the psychological impact of highly realistic robots on different groups of people (e.g., children, the elderly). They can debate the ethical implications of using such robots in real-world scenarios like caregiving or companionship. | | | | | | | Sources to Learn More | | | | | | | Explanations and examples of the Uncanny Valley: https://www.verywellmind.com/what-is-the-uncanny-valley-4846247 | | | | | |
