Okapi: Mobile Speech Wireframes - Okapi is a fictional name I used for a confidential client. I was asked to create a quick series of spec wireframes for a high level user experience using speech on a non-specific mobile handset.
With a loose set of guidelines, I worked on a quick medium-fidelity flow of a typical experience for most mobile devices -- listening to music. Above are just a sampling of the overall flow. In addition, I created a more polished, but still general look & feel image for presentation.
