Mobile navigator

Whatever you say, only satellite GPS navigation1 is an indispensable thing for travelers, tourists, car owners and other lovers of orientation on the ground. But so far, for cell phones (with outlandish exceptions), the built-in GPS receiver is just exotic and nothing more. Meanwhile, there is another mobile solution that allows you to save information about the route, keep its timing and remember the return route. The solution, in place, is software. Probably, many, having read the last instruction, also grunted and prepared to repeat the words of the legendary cat Matroskin: "Probably, there is an impressive capital ...". You aimlessly so, the program is free. In general, enough to feed our readers with intrigue, it's time to move on to the heroine of today's article.

TripMate - this is the name of this pocket navigator. Regular readers of Computerra Online should already be familiar with the creator of the application, Konstantin Knizhnik, from our previous 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 that supports Java technology (MIDP 1.0).

How does a cell navigator work? Simple enough. At the source of the route, select the New command, then in the process of moving around the area we mark each stage of the excursion and enter the necessary information (direction of travel plus, if desired, commentary). It is allowed not to think about the fleeting characteristics of the route, since the program automatically calculates the pore spent at each stage. At the halt or at the end of the tour, click Finish.

Now, at what time the route passed is stored in TripMate, it is allowed to go one more time in the direct (Navigate) or reverse course (Navigate Back). At the same time, the movement diagram (moving triangle) will be displayed on the phone’s display in graphic mode, only in textual mode — a detailed description of the route with the indication of the pores in the route of previously entered comments as well. We hope that the animations below clearly demonstrate the application’s working principle.

If you are moving along the route ahead of the schedule, then the Next button is useful to go to the next stage, only in case of a lag you can slow down / activate the program execution using the Suspend / Resume keys.

The current version of TripMate allows you to manipulate, unfortunately, so far only one route, but without limitation on the number of feasible stages (read, the duration of the trip). Moreover, each of them is subsequently allowed to edit or add a series of new stages.

To summarize. The program is no doubt interesting. Take at least the possibility of automatic timing, remembering the directions of the course as well as a graphical display of the route traveled. So, if you lost in the labyrinths of fate, you won’t find the chosen weapon to find a way out.
