The interaction design (IxD), commonly use to get real and great experiences, is used to let the user know the whole product before the final launch. This is really important for the company such for the user too, because try the product making different test on many people is the sign you are going to have a huge impact and great results.
IxD is the practise of designing interactive and digital products, systems or services for the society. The whole concept will explore how a user might interact with the product, when, and why, so it can mutate based on the need of users. Analysis is very important, interviews and let the users speak frequently, every single time something doesn’t work, you have to watch out and try again, that is the key to get a great interactivity and user experience.
