Abstract :
In this issue, editors Eyal de Lara and Maria Ebling cover initiatives for building a ubiquitous city and rewarding excellence in the design of virtual worlds. They also highlight a robot that scares away pest birds, technology that harvests electricity from the wind generated by passing traffic, a taxi navigation system, an adaptor that provides Ethernet connectivity over residential power lines, and a bracelet that vibrates when your cell phone rings. Finally, they present a cell phone that can sense motion.
