1. Transform Android into an OS people fall in love with. “We knew as designers that, for a really successful product, people should be having a stronger emotional reaction,” Duarte says. “They should be talking about how much they love it, how much they desire it, how much they appreciate it.” 2. Make Android truly simple and straightforward to use. “People know that Android is powerful, and they’ve felt a little bad about it when they can’t figure it out,” Duarte says. “We want to turn that around and make you feel like you completely understand the system.” 3. Have users associate Android’s cutting-edge innovations with things that will turbo-charge their own lives. Google is constantly turning out pioneering features, like voice actions or, the latest, Face Unlock, which allows you to unlock your phone using facial recognition software. Android wants users to have the feeling that “the technology is not just there for technology’s sake,” Duarte says, “but it’s there to make you an amazing person—to essentially unlock your own digital superpowers.”
