Gabor Cselle é Gerente de Produtos no Google e publicou em seu blog uma lista de oito tipos de experiência que os usuários apreciam.

Segundo ele, despertar essas emoções nos usuários pode aumentar a probabilidade de que eles retornem ao seu site ou aplicação.

1. Immediacy - Speed is addictive because speed is power. Remember how powerful you felt when you first used Google in 2000?
2. Looking at Faces - Humans are highly evolved to analyze faces and like doing it.
3. Learning - The feeling you get when you’re watching a great TED talk. Easily digestible, well paced, clear insights. The majority of media and blogs cater to this emotion: Think about how coming back to TechCrunch each day makes you feel like you just got another piece of candy.
4. Showing Off - The sense of pride you feel when you post your run to Nike+, get a “Player” badge on Foursquare, or post good looking party pictures to Facebook.
5. Influence - You got retweeted, or your post gets reshared on Facebook. Your expertise was appreciated. Klout, your follower count, and Coderwall all cater to this.
6. Simplicity, clarity, efficiency, safety - All of these are correlated sensations. Everyone loves a product with these properties. Yet this is pretty hard to hit, especially in older products that have gone through more development cycles and have become more complex.
7. Controversy - Humans love drama. Think Huffington Post – huge headlines mixed with animosity attracts attention.
8. Checking Items off a list - Few things are as stressful as an unread email counter or a todo list with unchecked items. Checking them gives you a sense of accomplishment.
