Archive for the ‘locative media’ Category

This blog post presents a review of the support for three web standards in mobile browsers: Geolocation, HTML audio and Media Capture. It is actually an excerpt from a draft paper about mobile web apps vs native apps that I am writing for the Nordmedia conference in august. I thought readers of this blog might be interested in the information, so decided to put it here as well. Any comments or corrections appreciated!

Locative media web apps like textopia or Anders Fagerjord’s MUCH project, rely on web standards for positioning and audio playback. A third capability that may be important for applications that wish to invite user contributions, is media capture – that is, the ability to record sounds and images using the device’s microphone and camera.

Positioning in mobile web applications is made possible by the W3C “Geolocation API” (Geolocation Working Group 2010), whereas media playback is enabled in HTML5 by the <audio> and <video> elements. These standards are currently being supported by the default browser in three of the four best-selling smartphone platforms – that is, Android, iOS and Blackberry.

tomi ahonen has an interesting warning about the mobile/ipad apps market, comparing it to the dotcom bubble ten years ago. and the numbers speak quite clearly: according to morgan stanley, total iphone apps revenues in 2009 were 780m dollars. minus 30% to apple, that is 546m. so at the end of 2009 there were over 100,000 apps in the store – which gives us a revenue per app of around 5000 dollars.

sarah epps at ars technica is proposing a new concept for the ipad age: curated computing, defined as “a mode of computing where choice is constrained to deliver less complex, more relevant experiences”. apparently the idea is that the iphone os, which also powers the ipad, ” runs more like a jukebox than a desktop, asking consumers to choose (and often pay for) applications from a predetermined set list” – in other words, it’s the internet without all the clutter, no shit only gold. consumption paradise, productive activities go elsewhere.

it’s not a particularly original analysis, but eliot buskirk at wired.com tries to expand on the idea to propose the “age of curation“. for him, the concept sums up everything from social media to original journalism, at which point the concept seems to have been watered down to mean everything and nothing.

which is sad, because the concept actually does seem apt to shed some light on where the ipad is being positioned in this new niche of computing.

i have just figured out how to make locative media applications that work across different mobile platforms. that is, one application that works both on the iphone, android, maemo and probably soon any other mobile platform. how? through the browser-based w3c geolocation api. i briefly mentioned this in yesterday’s post, but was suffering under the misunderstanding that this was somehow still a vision for the future. it is not! the geolocation api is currently supported by the iphone os (3.0), android (2.* – gears geolocation works in 1.6), and anywhere you can use firefox (on mobile, that is currently only nokia’s maemo and the upcoming MeeGo, but the android version is on its way).

here’s a good overview, which introduces a third option (geo.js) which claims to support several other platforms such as blackberry, nokia n97, windows mobile, palm pre and more.

wired reports that apple has turned 180 degrees in its embarrasing rejection of political cartoonist Mark Fiore, inviting him to resubmit his previously rejected iphone app so they can approve it and escape all the bad PR they’ve been getting. incredibly, apple cited the following reason for initially rejecting Fiore’s app:

“it contains content that ridicules public figures and is in violation of Section 3.3.14 from the iPhone Developer Program License Agreement which states: Applications may be rejected if they contain content or materials of any kind (text, graphics, images, photographs, sounds, etc.) that in Apple’s reasonable judgment may be found objectionable, for example, materials that may be considered obscene, pornographic, or defamatory.”

i just came across a very neat service: the norwegian post and telecommunications authority have launched the website finnsenderen.no, which allows you to see all the cell towers around the place that you live (or anywhere else).

cell towers around ntnu campus at gløshaugen, in trondheim

that in itself may not be very useful information, but it does give some indication of signal strength – and perhaps the accuracy of cell tower-based positioning – in any given area. more importantly, if the authorities would also release the information in a more suitable format, e.g. a database, it could be used to build hybrid positioning systems of the kind used by google maps, skyhook, navizon etc. this could even be done as an open source project. (in its current form, the map doesn’t seem to include all the info that is needed – some kind of tower id would at least be necessary). imagine that, the norwegian authorities supplying public data free of charge back to the public! it would be so logical and reasonable that we can only dream that it will ever happen.
