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?

The Samsung Galaxy S4

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.

Touch and use even with gloves - Samsung Galaxy S4Samsung claim the latest edition of its Galaxy is usable even with gloves on, hopefully reducing the cases of zombie fingers – Jonny, you might be able to use it! 😉

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.

What is Shodan?

EDITOR NOTE: This is Jonny’s 75th post on Technology Bloggers! Jonny was a complete newbie to blogging when he wrote his first post (about prosthetic limbs) but he is now somewhat of an expert – although he probably wouldn’t agree! – note by Christopher

Recently a couple of articles have appeared on large US websites about a type of search engine called Shodan. This search engine has been about for about 3 years, but it is different from Google and its cohorts in many ways. I looked at it and could not understand it at all, so what is it then and why is it causing such concern?

I have seen Shodan described as “The scariest search engine on the Internet”. This CNN money article explains that Shodan navigates the Internet’s back channels. It’s a kind of “dark” Google, looking for the servers, webcams, printers, routers and all the other stuff that is connected to and makes up the Internet.

What interest could there be in such capability? Well a lot apparently. The system allows an individual to find security cameras, cooling systems and all types of home control systems that we have connected to the Internet. (See Christopher’s series about his British Gas system here).

One serious problem is that many of these systems have little or no security because they are not perceived as threatened. Shodan searchers have however found control systems for a water park, a gas station, a hotel wine cooler and a crematorium. Cybersecurity researchers have even located command and control systems for nuclear power plants and a particle-accelerating cyclotron by using Shodan.

Hacking apart it turns out that the world is full of systems that are attached via router to the office computer and web server, and on to the outside world. Access for anyone who can find them and might like to turn of the refrigeration at the local ice rink, shut down a city’s traffic lights or just turn off a hydroelectric plant.

The Shodan system was designed to help police forces and others who might have legitimate need for such a tool, but what when it gets into the wrong hands. Security is non existent, just get your free account and do a few searches and see what you find.

See this Tech News World article for a further look at the ethical and practical issues that such a freely available product might bring

Regular readers will be aware of my interest in these types of problems through my work at the Bassetti Foundation for Responsible Innovation. I am not sure how the development and marketing of such a tool could be seen as responsible behaviour, but as I have been told on many occasions during interviews there are plenty of other ways of finding out such things. These types of systems are gathering already available information to make it usable, nothing more, so not doing anything wrong.

Do you agree?
