This document discusses mobile interactive services and their potential uses. It notes that camera phones are now ubiquitous, with over 90% of handsets having cameras. Examples of interactive mobile applications are given, such as using photos for image recognition, zoning images to interact with events, inserting faces into videos, and visual search. The future potential of mobile interactivity is large, including connecting to live events, 3D products, and using photos as a visual search tool.
