I work at a company where I am the first Interaction Designer they've ever had. And this company doesn't want me to touch the surface of the graphic design of user interfaces. They are new to interaction design and I feel I have to explain them a lot about my expertise. But they seem not so open to discuss my part of interface design. They seem not be able to understand how the graphic part of interface design and usability are intertwined. So no Photoshop.
I feel a little uneasy in explaining them how these are intertwined, it feels almost to much too explain. How would you explain the difference between graphic design in general and graphic design related to designing user interfaces from a interaction design point of view? How would you explain the importance of the latter? Has anyone has experienced similar situations?
