Mobile navigator

Whatever you say, only satellite GPS navigation1 is an indispensable thing for travelers, tourists, car owners and other orienteers. But for the moment, for cellular phones (with a rare exception), the built-in GPS receiver is just no exotics, no more. And meanwhile, there is another mobile solution that allows you to save information about the route, to keep its timing also memorize the return route. The solution, to the place, is software. Probably, many, after reading the last prescription, snorted and also prepared to repeat the words of the legendary cat Matroskina: "I bet, the capital is impressive ...". Aimlessly you are so, the program is free. In general, enough to feed our readers with intrigues, it's time to move on to the heroine of today's note.

TripMate - this is the name of this pocket navigator. With the creator of the application - Konstantin Knizhnik - regular readers of "Computer-Online" should already exist familiar from our past publications in the mobile section. The Java MIDlet developed by him occupies 19 KB in the phone's memory and is also functional on any device supporting Java technology (MIDP 1.0).

How does the mobile navigator work? Simple enough. At the source of the route, we select the New command, then in the process of moving around the terrain we mark each stage of the excursion and also enter the necessary information (the course direction plus, if desired, comment). The fleeting characteristics of the route are allowed to not think at all, since the program automatically counts the expended pore at each stage. At the end of the tour or at the end of the tour, click Finish.

Now, at what time the traversed route is stored in TripMate memory, it is allowed to go through one more time in the direct (Navigate) or reverse (Navigate Back). In this case, the graphical display of the phone will show the scheme of the move (the moving triangle), only in the text mode - a detailed description of the route, indicating the pores in the route as well as the comments entered earlier. We hope that the animations shown below clearly demonstrate the principle of the application's work.

If you are moving along the route ahead of schedule, then the Next button will come in handy for the next stage, only in case of delay, you can slow down / activate the execution of the program with the Suspend / Resume keys.

The current version of TripMate allows you to manipulate, unfortunately, for the time being only one route, but without limiting the number of feasible stages (read, the duration of the trip). In this case, each of them is allowed to edit or add a series of new stages.

Let's sum up. The program is without a doubt interesting. Take at least the possibility of maintaining automatic timing, remembering the directions of motion, as well as graphical representation of the scheme of the passed route. So, if you get lost in the labyrinths of fate, you can not find a chosen weapon for finding a way out.
