Is communication designing is similar to interaction design

Yes. Generally UX is taken to be an umbrella term. It was originally coined to help people think more holistically than just “pixels on a screen” - UI. As an umbrella term it encompasses a number of things that don’t even have pixels, such as customer journeys, or unboxing. This is one reason that UX people will say things like “design strategy is product strategy” and “the design is done when the product is end-of-life.”

Communication design generally focuses on the delivery of specific messages, usually within constraints and contexts. For example, a communication designer would be concerned with how to get a person to notice and perhaps click on a specific ad when they are looking at a Web page that may have many competing ads. A communication designer would immerse themselves in the language of the people they want to speak to so that, for example, when a busy nurse looks at instructions on a package, the nurse doesn’t have to stop and mentally “translate” those words - they should be the words that the nurse expects, including abbreviations, jargon, chemical names, etc.

“Messaging” is an important part of user experience, and the skill of any given UX professional at this part may vary. If your product’s success depends particularly heavily on this, then it may be worth hiring someone with this specialization.

There are countless types of design, from graphic design and interior design, to fashion design and industrial design, the list goes on and on. Add to those, the multiple facets of each (e.g. graphic design branches off into print design, type design, logo design, and interactive design) and you can quickly see how it starts to become unclear for some as to what the differences between each type of design are.

Since interactive design is an extension of graphic design, an interactive designer is well versed in the fundamentals of graphic design. For example, a web designer is a color theory, layout, hierarchy, contrast and typography expert, but goes beyond knowing the principles of graphic design and branches out into digital, UX/UI (user experience/user interface), strategy and even a little bit of psychology.
