The Perspective Engine is an AI tool that automates the process of putting giant and unfamiliar numbers into familiar context, such as demonstrating the capacity of a CD-ROM with a stack of paper hundreds of feet tall. It is already live in Bing, where it improves the answer to the questions like “How big is Afghanistan?” by supplementing “251,827 square miles” with the context “about the size of Texas” for US readers. It puts demographics, nutritional information, fuel efficiency and much more into perspective. Our demo will feature interactive touchscreen guessing games about unfamiliar numbers and will show people how the Perspective Engine can help make these numbers easier to understand. We will demonstrate the Perspective Engine in Bing, Microsoft Edge, and Office365.
