I'm an introvert. I am reluctant to speak up in groups but I have always felt like I have something to say. Design, and visual design in particular, is a way of speaking or communicating. This was true in my early days as an exhibit designer and it is true in my work as an interaction designer. It is also the case for the presentations I've assembled over the years to visualize issues for clients and co-workers. I have always been as fascinated by the effort to communicate the idea as I am in the idea itself.
Maps are another example of my interest in design and communication. They are deeply immersive. They hover between the visual and verbal. They are words that we read and images that we view. As visual and language-using animals inhabiting a world we seek to understand, maps represent the pinnacle of media. This is why I love creating maps.
Design for me is the opportunity to "speak" to people and to do it in a way that engages our visual and verbal nature. It is my attempt to find my voice.
