What is Uncanny Valley effect?

Answer 1

The Uncanny Valley effect refers to a phenomenon where humanoid robots or computer-generated characters evoke feelings of unease or discomfort in observers when they closely resemble humans but are not quite lifelike. This effect typically occurs in the "valley" of a graph that plots emotional response against human likeness, where robots or characters that are almost human but have subtle imperfections can trigger feelings of eeriness. The concept highlights the importance of realism in design and how small deviations from human norms can lead to negative emotional responses.
