General:
POIBeep is a POI (Points of interest) warner for Windows Mobile 5 based Pocket
PCs.
It uses the GPS applet integrated in WM5 to control the GPS, then it will only
work on this operating system. There are several PDAs where the OEM have
disabled this GPS control Panel Applet, like QTEQ S200 and others. In these
machines the applet can be enabled deleting any "Hide" or "Redirect" entry from
the following registry key to enable it:
HKEY_LOCAL_MACHINE/ControlPanel/GPSSettings.
POIs are read from a ov2 file (the TomTom format) that must be in the same
folder (usually \program files\POIbeep) and must be named POI.ov2. I've included
a Spanish traffic radar file as example. Also I've included two freeware tools
from TomTom: makeov2.exe and dumpov2.exe that could help doing our own POI.ov2
files.
POIBeep is VGA and QVGA compatible. Next version will support also landscape
mode and quad display. While POIbeep is working, automatic backlight and PDA off
are disabled.
How it works:
When POIBeep starts it looks for two files along with POI.ov2 in its folder.
These files allow the automatic or manual (by means of highway icon) of
the GPS navigation program that could run in foreground. To make these files we
could use the file that exists in "\Windows\Start menu\Programs" copiing it to
the POIBeep folder and renaming it, or we could create a new one from the
navigator exe file.
In any case, the navigator program is executed in low priority mode, as well
known program TTN5Bot does, allowing simultaneous work of POIbeep and navigator
without problems. The files to create are:
-NavApp.lnk: If this file exists, it is automatically ran and when the
program exists POIBeep exists too. This options is for background use of POIBeep
without having to launch manually the navigator.
-NavAppButton.lnk: If this file exists, it is assigned to the Highway icon on
the POIBeep screen, and executed if the icon is tapped. Exiting this programs
POIBeep continues running.
Bluetooth icon allows to turn on/off bluetooth from POIBeep. It works with
Microsoft and Broadcom (Widcomm) stacks.
Mute icon turn off POI audible signal. It doesn't affect to the PPC audio.
Exit icon exits the program.
POIs warnning:
In POIBeep screen we have a radar "North-up" oriented plus a small
information area above the radar.
When the program starts, it shows version, number of POIs read from the POI
file and number of GPS satellites that can be seen. When among these satellites
there are at least three with enough signal, the message change to blue and
shows actual speed and angle to north.
In the radar display the scanned sector will be shown in a light green. The
centre line of the sector indicates the actual direction of traveling. POIs that
are under this scanned sector are tested continually.
How POIs are warned:
 | -Scanned sector are centered in our direction and may be from +-30º at
50Kmh or less and +-10º at 100Kmh or more. |
| -Detected POIs under scanned sector are shown as red dots, outside
scanned sector thy will be blue. |
| -There are two circles concentric with our actual position, blue is 30
second away and red is 15 seconds away at our actual speed. |
| -If a red POI enters in the circles, a sound will be played. This sound
is different for 15 and 30 seconds circles. This warn will remain playing
until the POI will get out of the scanned sector. |
| -If actual speed is too slow, circles will be fixed on 500meters for
blue one and 250meters for red one in order to be useful also at low speeds. |
| -Maximum radius scanned is 2Km, that is a 240Kmh for 30 seconds. This is
why this program can also be used on bicycles. |
