Cybernet has developed a prototype mobile maintenance system specifically targeted to ship-based Sailors.  The Shipboard Wireless Maintenance Assistant (SWMA) provides sailors with on-site, on-demand access to vital technical data in a variety of ways, including: portable digital displays for graphical data (schematics, IETMs, etc); wireless access to maintenance databases; integrated set of diagnostic tools; and real-time sharing of duplex audio and video between technicians and remote experts. The SWMA system allows multiple technicians to collaborate on a common problem, regardless of their physical location aboard the ship using a handheld communicator with video, audio, text and applications shared over a ship-based network.  This system supports technical collaboration between technicians with differing experience levels, leading to faster and more efficient resolution to technical problems on board.
