The Answer, the O’Reilly Where 2.0 Online Conference. (http://en.oreilly.com/wherefall09/). This was an online conference focused on utilisation of the Apple iPhone sensors and how applications can easily be built to use these sensors in weird and wonderful ways. Quite an insightful conference and I was amazed at how awake I was particularly at 1am in the morning.
So why I would attend an online conference particularly at 1am in the morning?
- Most importantly, allows me to attend in my PJs as the conference was run on New York time,
- Online participation is exceedingly high. No more waiting for someone to stand up and ask that first question. Just type away!
- Can save the presentations as they are given.
- My work did not want to fork out the costs of sending me over to America.
The online conference turned out to be a bit of a code fest although I did gain some pretty insightful knowledge in what goes into building an application. It was especially interesting to see how the sensors are being used and what the developers would like to see added. So lesson one, these are the sensors in your modern iPhone:
- The Accelerometer – This pivots and turns the screen based on the movement of the iPhone,
- The Magnetometer – The digital compass in the 3Gs and the basis of many new and cool applications for the iPhone.
- The GPS Reciever – this is what give you your location although the phone refers back to triangulation (~700m accuracy) when you don’t have clear line of sight to the sky.
- The Proximity sensor – This turns the screen off so you don’t accidentally hang up while talking to someone on the phone!
The Where 2.0 conference setup this dedicated session on the iPhone as it is the most dominate ‘smart’ phone in Australia (and most places in the world for that matter) and for the fact that more spatial data requests and captures will happen on devices like these in the future than from traditional GIS desktop applications. In fact it was predicted back in 1999 by Max Egenhofer speaking at the 1st Brazillian Workshop on GeoInformatics (http://www.spatial.maine.edu/~max/pubs.html) that the smart phone would be the leading GIS device of the future
“Spatial Information Appliances – portable tools for professional users and a public audience alike, relying on fundamentally different interaction metaphors: Smart Compasses that point users into the direction of certain points of interest, Smart Horizons that allow users to look beyond their real-world field of view or Geo-Wands – intelligent geographic pointers that allow users to identify geographic objects by pointing towards them”

Sounds pretty cool hey? Lesson two, it may not be widely known in the spatial sector since we generally deal with top end GNSS receivers but companies like Apple and Nokia alike are the biggest GPS receiver sellers and consumers in the world. Knowing this I feel that it would almost be right in saying that these companies are the new leaders in GPS and navigation. Certainly mobile mapping is the new fad and with so many people out there collecting and geo-tagging information it seems likely that this is the new way for us to collect information.
It was nice to listen and provide input into this conference considering in each presentation, ‘location’ was key to the applications being talked about and how the future would be built around utilisation of GPS to a higher degree. At around 4am in the morning I perked up at mention of a new iPhone application called ‘Theodolite’. http://hunter.pairsite.com/theodolite/
Imagine this, a surveying term wrapped up in a surveying application for the iPhone. Ok, now I know the GPS receiver in the iPhone is accurate to ~40 metres and so this isn’t a surveying application but the future looks bright.
I talked about Wikitude and a little on augmented reality in a previous post and attending this conference re-assured me that this new technology can really make it in this mobile mapping, smart phone, social media age. I don’t think we will be calling our phones “GeoWands” in the future but damm they are cool.
