Google recently updated its login page, such that they now ask for the username and the password on separate pages. This makes things easier because then I just type in the username, hit enter, then type the password. For novice users (who are not fans of tabbing) this is definitely more usable.
I also came across this company that uses this concept to incrementally fill forms, questionnaires, etc.. This is a link to the website: http://www.typeform.com/examples/#Forms
I want to do some research to see if there has been studies on how users perceive these types of forms compared to standard ones. But I am missing the right keywords.. Is there a certain term to describe this type of forms?
