Karolina Kurkova wears Met Gala dress designed by IBM Watson

The CognitiveDress is a collaboration between IBM and fashion house Marchesa, and reacts to emotions expressed on social media.

At Monday night's New York Met Gala held at the Metropolitan Museum of Art, the theme is Manus x Machina, and technology is hitting the red carpet. Model Karolina Kurkova revealed on Twitter that she is wearing a dress designed by fashion house Marchesa's Georgina Chapman and Keren Craig, embedded with IBM Watson technology that reacts to social media in real-time.

The dress is covered in fabric flowers with LEDs inside; as users on social media respond to the Met Gala, the flowers will glow brightly. Marchesa told CBS News there are five key emotions it will search for on social media: joy, passion, excitement, encouragement and curiosity. When it detects these emotions, the dress changes colors in real time.
