THE FUTURE IS NOW
When electronic media meets technology there will always be an access point, called an interface, that allows us to interact with it.
The first hurdle an audience needs to overcome is understanding how to get access. Whether it's through a screen, a touchpad, or mouse and keyboard makes no difference - they all provide access.
As a technical communicator, I can help remove hurdles to improve user interactions (UI). Those improved interactions, in turn, make the user experience (UX) better.
UX is the culmination of all aspects of the user's interaction with the company, its services, and products. Improving UI also improves UX, which can lead to happier customers and more profitable companies.
