Description

Program helping you to remember the route.
It cab be route from conference room to coffee-room, it can be tourist trip, it can be pathway in labyrinth. during first traversal you make notes in you phone, specifying direction of movement and target of each step. Phone remembers how much time each steps takes. Then you can just inspect information about this trip and check duration of each stage and the whole trip. You can also replay it in forward and backward direction. So if somebody show you the shortest way to coffee machine, you can easily find the way back and can repeat this trip in future.

Description

  • The main menu of TripMate contains list of trips. Add new trip and specify its description. The program automatically switches to the mode of specifying the trip. In this mode you are adding trip points. For each point you should specify direction and optional description (target). When all steps are specified, choose Finish command to end the trip. It is possible to edit description and direction of each point, but it is not possible to add or remove new points to the trip. If you close application in enter trip mode, it will be in the same mode after restart. TripMate automatically calculate time of each stage (point time is set when you execute Enter command)
  • When trip is finished, you can view and edit trip points (List command) and relay trip in forward or backward direction (Navigation command). Navigation is performed using the same time scale. You can suspend/resume navigation or visa versa move current position to the next point. Navigation is perform in graphic or text mode. In graphic mode, TripMate shows movement of marker through the graph representing the route. In text mode, it shows description of next point, elapsed and left time for each step and the whole trip.
  • When navigation is suspended, current position cursor start rotation. When navigation is finished (last point is reached), arrow cursor is replaced with filled circle.

Description

This is vector map of Moscow with more than 3000 streets and metro stations.
The vector map of almost any city in Polish format can be easily converted to be used by this application. Because of limits on jar file size and small screen resolution, number of layers is restricted.

Notes

  • You can use mobile cursor key to scroll the map in four main directions. You can also use digit keys to scroll the map and change scale. Keys are naturally mapped to the correspondent directions. Meaning of keys is explained in Help. '*' key can be used to zoom in and '#' - to zoom out. '0' - shows the view of the whole city and '5' - opens search dialogue.
  • To search street by name choose correspondent command or press '5' button. Then specify street prefix. The program will show list of all streets with such prefix or next 10 streets if streets with such prefix are not found. Then you can select particular street and it will be marked with pink color at the map.
  • Version 2.0 of the applications provides a lot of additional features. It is able to display objects of different types - point objects: theaters, banks, restaurants... and objects with arbitrary shape: river, lake, park, forest... The program allows to search objects by names, select it from a list of correspondent category, get information about the object pointed by cursor at the map. It is also possible to find shortest/fastest route between two points. This version use full screen mode, to display command list just press left command button of your phone.

Maps | AriadneThread

Last release: 14.11.2007
Compatibility: Java MIDP 2.0/CLDC 1.1, JSR 179 (location API)
Java compatible phones with GPS

Description This midlet allows you to record your route and return backward using the same way or reach the same place once again. For example if you know some nice place in the forest, you can track the route to this place and give your phone to some other persons so that he can reach the same place (and what is more important - return back). I hope that this midlet will provide functionality not covered by stadnard navigational soft or GPS trackers, because first one usually not able to store routes and work without detailed map of the particular place and most of GPS trackers sends data to the PC where them can be visualized using Google map or similar service.

Notes

  • This midlet can work in two modes: recording mode and navigation mode.
    When you select 'New' command in route list, new route is created and GPS data is record with specified interval (default value is 10 seconds). In this mode the midlet displays at the bottom of the screen traveled distance, average speed and elapsed time. To stop recording and remember the route execute Stop command (popup menu appears when you press right button).
  • If you select existing route from the list or after finishing of recording of new route the midlet is switch to navigation mode. You can choose Forward or Backward direction for the route. End point of the route is marked with thick dot. If you do not select any direction the midlet will just show the current position, course, traveled distance, average speed and elapsed time (from the beginning of navigation). If you choose forward or backward direction, the midlet will find out a way to the nearest point in the route and gives you voice commands in which directions to go. Bottom line in this mode shows distance to the end of route, average speed and expected time of reaching the destination. To stop navigation press Stop command - you will return to the screen with list of routes.
  • In settings form it is possible to specify interval of polling GPS coordinates (seconds) and minimal step = distance between two subsequent recorded positions. Lower interval value increase precision of recording but also increase storage consumption. Smaller intervals are preferable for trips with high speed (car or bike) while for walking 10 seconds seems to be more than enough.
  • Voice commands includes "Turn left", "Turn right", "Turn back" and notification message "You reach destination". This midlet contains russian version of the commands. To change it to the commands in your language, replace correspondent *.wav files is res directory and rebuild midlet.

Map of center of Brno (Czeck Republic), MIDP 2.0 version (0.5Mb)
Sources:
mapbrowser-src.zip (2.1Mb)
mapbrowser2-src.zip (1Mb)

Description Yet another map browser for mobile phone. Now it is working with raster map. Certainly size of raster map is significantly larger than of vector map. That is why this midlet has size more than 2Mb and works only at Series 60 phone. This midlet is just an example, with raster map of Cairo and with almost no index data. But it is possible to load ANY map in it and specifiy information about city objects (hotels, restaurants,...) including thier photos in XML format.

Notes

  • You can choose one of two scales - key '5' or Enter can be used to zoom-in or zoom out. When you perfrom zoom-in, rectangle box specifies selected area which will be shown at the screeen after zoom-in.
  • Cursor keys are use to perform fast navigation in specified direction
  • Numeric keys 1,2,3,4,6,7,8,9 are used for precise positioning in correspondent direction. When you press key for a long time, autorepat mode is activated.
  • Key '*' is used to iterate through selected objects and '#' - to get information about current object.
  • It is possible to change current language

Description

Yet another map browser for mobile phone.
Now it is working with raster map. Certainly size of raster map is significantly larger than of vector map. That is why this midlet has size more than 2Mb and works only at Series 60 phone. This midlet is just an example, with raster map of Cairo and with almost no index data. But it is possible to load ANY map in it and specifiy information about city objects (hotels, restaurants,...) including thier photos in XML format.

Notes

  • OnlineMap used slightly different key mapping than MapBrowser: '*' key performs zoom-in, '#' - zoom-out. '5' allows to iterate through selected objects (if you select all objects of some category from the index). '0' or FIRE - get information about currently selected object.
  • When you select all objects from category, only those objects which present on the current screen will be marked. You can iterate through selected object on the screen using '5' key. If you scroll to some other screen, you can find out some other selected objects.
  • OnlineMap doesn't respond to the commands when map image is loaded.
  • It is possible to specify size of image cache. default cache size is 3 which allows to store all four images which in the worst case are present on the screen (last image is remembered in any case). If your application get OutOfMemory exception, you can try to decrease cache size. But it can significantly slow down movement of the cursor when it cross the boundary of two images.
