What are the job titles of people who design how software should look and feel?

In the construction industry, there's an architect:

An architect is a person trained to plan and design buildings, and oversee their construction

and an interior designer:

Interior design describes a group of various yet related projects that involve turning an interior space into an "effective setting for the range of human activities" that are to take place there

What are the software industry equivalents of these jobs?

I'm interested in what are the common titles of people who design how software should look and be interacted with?

Am I thinking of an interface architect, a user experience expert or something else?

Answer

I would call them X designer where X can be Interaction, User Experience, User Interface, Information, Graphic or null.

So Interaction Designer, User Experience Designer, User Interface designer, User Experience Engineer, Information Architect, Information Designer, Graphic Designer or just Designer. This is especially true in small companies where the roles are multiple and you do a lot of different things.

In larger cooperations the "look" is handled by the Graphic Designer and the "feel" by the Interaction Designer.
