In this column, editors Keith Farkas and Eyal de Lara review a Bluetooth-based proximity broadcasting system and a Wi-Fi watchdog system, both of which raise some privacy issues. They also review a video display that projects into thin air, technology enabling 3D TVs, and a production-quality two-way display, which is similar in spirit to the prototype we reviewed in the last column. Finally, they examine a virtual computer, an ultraportable personal server, a novel keyboard, and a bionic arm that suggests the future of human-computer integration.
