Google X was a project released by Google Labs on March 15, 2005 and rescinded a day later. It consisted of the traditional Google search bar, but it was made to look like the Dock user interfacefeature of Apple's Mac OS X operating system.

User experience (UX or UE) is the way a person feels about using a product, system, or service. User experience highlights the experiential, affective, meaningful, and valuable aspects of human-computer interaction and product ownership, but it also includes a person’s perceptions of the practical aspects such as utility, ease of use, and efficiency of the system. User experience is subjective in naturebecause it is about an individual’s feelings and thoughts about the system. User experience is dynamic because it changes over time as the circumstances change.
