Ms. Dewey

«Ms. Dewey is a search engine owned by Microsoft. It also refers to the character of the same name, who is the engine's main subject. The Ms. Dewey website is an Adobe Flash-based experimental interface for Windows Live Search. The interface features a futuristic city as a backdrop with the character on the left side, while the search results appear on the right. Developed by MRM and EVB, Ms. Dewey is a fully animated search assistant who audibly comments on searched keywords in her own style and makes random actions when idle. Microsoft is not openly marketing it, as they intend it to be explored by users in the natural way. Janina Gavankar plays the role of the Ms. Dewey character. »
