Books on Robots and Emotions

Are you interested in reading up on robots and emotions?

Here are some of the books I've come across while writing my thesis. I've put an "easy-to-read" rating on each one. The more stars, the more textbook-like it is, with research and modeling -- but it might be harder to dive into if you're a beginner.

The books with one ★ are easiest to read to get a quick overview of the field.
Books with ★★ are more comprehensive, and still readable.
Books with ★★★ are a compendium of papers from different researchers. Your mileage may vary.

In order of recommendation from me:

How to build an Emotional Robot
★★ Designing Sociable Robots, Cynthia Breazeal

Emotions for Human-Computer Interaction
★ Affective Computing, Rosalind Picard
★★★ Blueprint for Affective Computing, Klaus Scherer et al.

Artificial Intelligence based on Emotions
★★★Who Needs Emotions? The Brain Meets Robot, Jean-Marc Fellous and Michael Arbib

What are Emotions? Why do we need them?
★★ Descartes Error, Antonio Damasio

Emotion Design for Interfaces
★ Design for Emotion, Trevor Van Gorp
★ Emotional Design: Why we love or hate everyday things, Donald Norman (Last chapter is on robots)

Emotions, Personality - Faking It
★ The Media Equation, Byron Reeves and Clifford Nass (Only partly mentions emotions)

Social Implications of Emotional Robots
★★ Alone Together, Sherry Turkle [Warning: This book is very critical of robots with emotions.]

Bonus:
...and just a really well-edited book that can give you a fresh perspective on emotions. I love this book:

Emotion in Music
★★★Handbook of Music and Emotion, Patrik Juslin and John Sloboda
