In an article in today's Wall Street Journal called Ericsson Turns to Navigation it is reported that Ericsson is looking at navigation applications with voice commands as an revenue stream for their carrier partners. Everyone is getting into the act because the bigger screens on smartphones and mobile handheld PDAs like some lines from Ericsson, Blackberrys and iPhones make it easier to see maps and read directions while on the move.
Navigation applications and data for consumers will be quickly followed by applications designed for businesses. Navigation and voice directions can be integrated into delivery, work order and inspection applications on mobile handheld PDAs.
Google has already created consumer oriented applications for iPhones that let friends know where friends are on a map. It won't be long until businesses can also see the location of their employees, job sites and company vehicles via PDAs, handhelds and Smartphones. Google makes this application free. I believe applications like this will quickly become available as widgets or gadgets that any software developer can quickly add to their mobile application.
It is a fun and exciting time in the mobile handheld PDA technology world.
