Hi Thorsten,
that's a great idea!

Dear All,
I recently bought a Android-based phone and was pleased to see the
mobileorg version for Android. As you all may know people tend away
from
static computer places and we have mobileorg and some of us even run
emacs and org-mode natively on smartphones and other gadgets. More
and
more of this devices come with a build-in GPS or at least they get
can
get the current location by tracking the mobile phone towers.
Playing around with Android for a few days, I saw many applications
which make use of the fact that the location is known to them. E.g.
they
show restaurants, shops, or doctors praxis close to you.
I start wondering whether org-mode should get aware of my location
and
whether people might be interested to add a location tag to org-
mode tasks.
In a similar way as we add status, priorities, dates, tags, etc. It
might be interesting to add a location. A special agenda search could
list only those entries associated with my current location (or
within a
given circle).
Since GPS coordinates are somehow ugly and human unreadable, I
thought
it should be possible to mask them similar to links. E.g., like
[[gps://35.71083783530009,139.8175048828125][Somewhere in Japan
+3km]].
Obviously, the first part has to be generated by read out the GPS
location, the second part is a human readable description and a given
radius. Closing this "link" would end up in "Somewhere in Japan
+3km".
A "C-a l" could compile an agenda list only showing those entries
which
intersect with my current location.
`C-a' is bound to `beginning-of-line'.
`C-c a l' is still free.
But wouldn't a property more suitable for the agenda?
* TODO Something in Japan
:PROPERTIES:
:COORDS: gps://35.71083783530009,139.8175048828125
:END:
The `+3km' could be a default setting (and could be supplied as a
filter, just like tags).
(Somehow I see the `org address book' discussion coming up again.
Emacs
needs an address book we all use. Something that's delivered with
Emacs.)
Links could point to map.google.com. I'd like to use those links to
store tracks in Org-files as well. HTML-Export could support OSM or
Google-Maps to show the tracks. We also could produce SVGs or PNGs
from
the data.
Obviously, it requires to read in GPS data, which might be tricky
to do
for all those different devices. Furthermore, it might need emacs-
lisp
code as well as some external program to read-out the position of the
GPS module.
On Linux, BSD and MAC OS X there is `gpsd'. I don't know how useful
it is --- I don't own a GPS yet.
http://gpsd.berlios.de/ states:
gpsd is a service daemon that monitors one or more GPSes or AIS
receivers attached to a host computer through serial or USB ports,
making all data on the location/course/velocity of the sensors
available to be queried on TCP port 2947 of the host computer. With
gpsd, multiple location-aware client applications (such as
navigational and wardriving software) can share access to receivers
without contention or loss of data. Also, gpsd responds to queries
with a format that is substantially easier to parse than the NMEA
0183 emitted by most GPSes.
Is there something like it for other systems? Windows?
I think Cell phone systems should have something ...
But I guess the emacs-lisp gurus here might know this much
better then I do. Another issue comes to my mind for mobileorg
users. As
far as I know, mobileorg only fetches agenda views from a server but
does not generate them. However, this would be necessary to create
this
kind of location aware agendas.
Would be nice to hear other opinions. Makes this sens? Should it be
part
of mobileorg, or rather a independent package?
I'd make it an independent package. Some laptops come with a built in
GPS these days. And your desktop might know his GEO location as well.
We might have a variable `gps-home-coords' which is nice to have on
cell
phones as well (would be great to have several "homes" for some
people -
e.g. commuters).
Unfortunately I don't own a GPS yet. But I'm very interested in this
one and surely will contribute.
Best wishes
Sebastian
