Augmented Reality Art

3 Replies Jonny Hankins

A couple of weeks ago I crossed Grand Island in New York State, a rather desolate place at this time of year near the border with Canada. I was interested in a virtual art installation involving augmented reality, and quite a find it was too.

It turns out that in In September 1825, Major Mordecai Noah founded a city state called Ararat on Grand Island, “a city of refuge for the Jews”. His idea was to create a Jewish homeland. Noah’s dream never came to fruition, until that is a group of academics and artists decided to create a virtual tour of how the city might look today had it been constructed.

The tour involves downloading an app into your smartphone, and travelling to specific areas on the island. When you look through the camera of the phone various structures appear in the view that are not present in reality. There is a copy of a memorial that was designed but has fallen into decay, a synagogue, school, a theme park and various other typical structures. The group also produced postcards, stamps and money, as well as other objects in everyday use in any nation state. There is in fact only one original artefact from that period surviving today, a cornerstone that tells the story of the city’s foundation.

People who would like to take the tour have to download the mobile app Layar, and aim their devices’ cameras at the landscape. The application uses geolocation software to superimpose virtual objects at precise GPS coordinates, enabling the public to see the objects integrated into the physical location as if they existed in the real world.

Then you just take the photo and the object appears as if in real life, with your friends next to it if you like. The Mapping Arrarat website explains everything, and hosts a short video that demonstrates the installation in practice. There are also lots of photos of the various structures that show people interacting with a virtual landscape.

Although the computer graphics aren’t entirely convincing I am sure they will very quickly improve and get to the point of looking absolutely real, very much in the way that games have developed in recent years. And an installation of this type looks like a fantastic educational tool to me. Objects can be placed on the landscape and presumably old photos and plans could be used to re-make places and events. Wouldn’t it be interesting to go the the Great fire of London, or walk through antique Rome and come back with a few shots to show the family?

Boston Bombs and the Billboard Problem

5 Replies Jonny Hankins

As I am sure many of you will already know, last week was a difficult one to say the least for my fellow citizens of Boston and Cambridge.

The events have caused a debate here though about the use of advertising technology. In the US many places host digital billboards. They are enormous, bright, attract attention and the content can be changed at will, using a computer and not a pole with wallpaper paste on it. Many change every 10 or 20 seconds, allowing great generation of revenue for both the publicity companies and the cities and states that license their use.

I first saw something like these while watching the Premier League, boards that changed by the side of the pitch through a disk system, but the modern equivalent are just like watching giant TV’s, in HD quality no less.

So why the debate? Well it turns out that the FBI have contracts with the largest billboard operators, and they can take over any number of the appliances and show what they want. In the case of Boston the contract is with Clear Channel Communications, and this allowed the FBI to show the photos of the two presumed bombers. Direct to the public marketing, for those of us still living without TV and smartphone (yes I am).

But many groups argue that the billboards themselves are dangerous and present a distraction to drivers, and many are placed in residential areas causing numerous complaints. Light pollution as much as skyline destruction are both problems when they are placed in residential or historic areas. The City of Los Angeles has in fact recently taken many of them offline on these grounds as this article explains, and pressure groups exist that campaign for their removal.

A Distraction?

A Distraction or an eyesore?

In all fairness they are not all trying to ban them, but to place them only in commercial districts where they do not cause distraction, but as you might imagine this does not go down too well. Distraction (or attention anyway) is after all one of their main goals.

But there is a lot of money involved. The city of Chicago hopes to raise $155 million by placing billboards throughout the city. The City recently approved a deal as this article explains.

The State of New Jersey has just struck down a ban on their use, again hoping to raise much needed funds.

The FBI argue that they are useful tools in crime prevention, stating that they have already apprehended 51 fugitives after posting their faces on billboards, and insist on their position as a public good. The debate rages and I am sure will continue on for some time.

The Scenic America website offers links to several safety studies regarding digital billboards for the interested reader.

On a lighter note and thinking about my post last week I wonder if they are on Shodan and easily hacked? That might be interesting.

The Samsung Galaxy S4

24 Replies Christopher Roberts

This coming Saturday, Samsung’s latest smartphone, the Galaxy S4, goes on sale.

Smartphone Battles

2009-2012 smartphone market by provider

Global smartphone market share by provider.

Like with most mass market technology, there is a war going on in the smartphone industry. In 2012, according to market analyst firm ICD, Samsung controlled 30.3% of the global smartphone market, 59.5% up on the 19% of the market it controlled the year before.

There is no doubt that Samsung is currently the dominant force in the smartphone market. The firm seems to slowly be winning its battle with Apple, and looks set to take on Google next, with rumours that it soon plans to ditch Google’s Android operating system altogether.

Nokia are predicted to make a comeback (how successful I am unsure) thanks to Windows RT, and makers of BlackBerry, RIM, are also looking stronger in 2013 after the release of BlackBerry 10 earlier this year.

Galaxy S4

Samsung are trying to steal even more of the market from its competitors with the Galaxy S4, so it has pulled out a few stops, maybe not all the stops, but quite a few, to make sure that the phone is a success.

So, the phone has loads of new features, to make it slightly better than its predecessor – the S3.

The S4 has a slightly bigger (5mm to be exact) screen, boasting a whole 5 inches of full HD display, which no doubt gives it amazing clarity. The new phone is also slightly thinner than the S3.

You can buy a Galaxy S4 in black and white, or as Samsung like to call them: black mist and white frost. I have never looked at a phone before (smart or not) and thought “that looks like frost” or mist, but maybe the S4 really does; or maybe it’s just marketing.

The phone has various other new features, such as Samsung WatchON, which connects your phone to your TV, turning your phone into a remote control.

Another new feature is the multi-speaker capability – if you have more than one handy, you can sync them together to create a better quality of sound.

The S4 will also come with built in 4G compatibility, which the original S3 didn’t. If a fast internet connection is important to you when you are on the go, then the S4 is probably a better choice than the S3.

Eye-Tracking

Probably the most exciting new feature of the Galaxy S4 is the new eye-tracking technology. The phone uses its front camera to monitor the users eye movements, and uses can use this function for a host of different activities.

One of the features which uses the eye-tracking technology is video playback. If you are watching something, and then look away, the device automatically pauses the media for you. Furthermore, eye-tracking technology can be used to scroll up and down a page, without the need to even touch the screen.

Photos

There are two interesting developments in the photographic area of the phone, the first is that you can now add audio snippets to pictures, to enable you to catch even more of the moment. You can also merge video with picture, creating partially animated pictures – sort of like the photographs in the Harry Potter films.

The S4 can also use (and display) the front and rear camera simultaneously, which shows that its quad-core ARM processor is pretty quick!

Your Thoughts

So what are your thoughts on the S4? If you are getting one, do let us know!

Do you think that Samsung have done enough to fend off the competition from its closest rivals?

Personally I think the S4 looks like it is set to become the best smartphone on the market when it goes live at the end of the week.
