In this issue, editors Eyal de Lara and Maria Ebling cover an application that will help the deaf communicate via mobile phones using American Sign Language and a navigation application that uses 3D images to help people better orient maps to the environment. They cover a service that helps protect users' privacy from acquaintances and another that supports text messaging conferences. They also present a smart refrigerator, a smart shoe, and a book reader with a rollup display, and a wireless hard disk that stores audio/video files and lets you access them from a variety of entertainment devices.
