Both interaction designers and information architects want to design objects with a singular meaning – a noble, albeit impossible goal. The best we can hope for is to create more consistently meaningful experiences. To do that, designers must better understand the interplay between designer intention and user interpretation: the ways that we can influence – but not dictate – user interpretation.
Consider the design of a voice-based interface. Because users can say what they mean in any number of ways, there are many situations for which designers cannot account – especially in the first iteration. Designers proactively create a set of interactions that users might accomplish, but the diversity of “common” speech patterns prevents a more prescriptive, task-oriented solution.
