According to Ecem Keskin director of product design at JotForm many people think UX is sketching and wire framing interfaces. However, UX design is the life cycle of the product.
“Some people think design means how it looks but of course, if you dig deeper, it’s really how it works”, Steve Jobs
Basically, UI defines the overall design, look and feel of the product and plays a significant role on first impressions. UX defines the interaction models, tasks, flows and creates communication scenarios with users. Definitely, users’ happiness mostly depends on the UX design.
