Different Use Cases involve different specs. Considering the surroundings, distance to the screen and characteristics of the users, the interface has to be adjusted. My aspiration is to get a seamless balance between input, output and interface.
Next to the visual component of a design, there is also an invisible part. Like between humans, every interaction creates a relation. While communicating with computers, we start to create feelings like trust, frustration or joy. That's why my job is also about shaping these relations through design.
Visual Designers may command design parameters, but it's much harder to predict pain points of the user. That's why I see the users as a co-developer. In iterative working cycles with a human centered approach I feel most comfortable with.
