Mobile Augmented Reality
With the increase in onboard computing power in todays mobile devices,
the use of augmented reality is finding it's way into every day,
mass market applications.
Nokia Mobile Augmented Reality Prototype
NOKIAS AR PROTOYPE
By adding a GPS sensor, a compass, and accelerometers to a Nokia
smart phone, and using data from these sensors, the phone can calculate
the location of many objects its camera is aimed at.
Whenver the phone changes location, it retrieves the names and
geographical coördinates of nearby landmarks from an external
Users can then download a wide array of information about a chosen
location from the Web.
Despite the technical capability, some skeptics claim that Nokias
application offers "too much complexity for a commercial application".
Total Immersion, an augmented-reality company in Suresnes, France,
believe that picture analysis is the solution.
Relying on software alone, Total Immersion's system begins with
a single still image, plus a rough digital model of the object,
and using image-recognition algorithms determine what data should
be superimposed on the image.
The company is already marketing a mobile version of its system
to cell-phone operators in Asia and Europe and expects the system's
first applications to be in gaming and advertising.
Nokia researchers have begun working on real-time image-recognition
algorithms as well, in the hope the algorithms will eliminate the
need for location sensors and improve their system's accuracy and
reliability. This will reduce the complexity and make the application
Regardless of the path, all parties agree that mobile augmented
reality is market ready. The mobile applications and technology
are both available. All that remains is convincing carriers such
as Sprint or Verizon that customers would pay for augmented-reality
services. Good luck with that!!
Uses For Mobile Augmented Reality
Local Area Guide
Finding your way around an unfamiliar area can be somewhat daunting.
In a car, you can use the assistance of a GPS car navigation system.
But knowing how to get from one street to another does not tell
you where a particular type of restaurant is, or find an ATM.
Mobile Augmented Reality Applications are not only helping visitors
get to desired locations, but also assisting them in what to do
when they get there and offer directions and offers to local featured
destinations: parks, tourist attractions, entertainment, restaurants,
Nokias Augmented Reality Prototype, displayed above, allows users
to capture a digital image of a building on their mobile phones,
and using this image, access location and information about the
Google Local Maps
Google Local Maps, is one such instance. Using Google Earth, users
are able to add a virtual construction of their building onto the
real satellite images. Another click and previous travelers tell
you their tales of 'wow' and 'woe'. And if you are driving, the
voice version is extremely useful.
is a project developed by the Augemented Reality Dept, Bauhaus University,
This project aims to develop and evaluate a new technique for optical
data exchange between public displays and mobile devices.
Using time-multiplexed, colored barcodes shown on displays and
captured by a camera-equipped cellphone, the challenge is to maximize
the data transfer and robustness of the barcode recognition, with
no immediate synchronization between the devices.
Although the transfer rate is much smaller than it can be achieved
with electromagnetic techniques[Bluetooth or WiFi], to aim is to
enable optical data transfer wherever no direct connection is available.
The time-multiplexed markers can be, for instance, integrated into
web-pages, movie sequences or advertisement presentations, and encode
more information that possible with a single barcode alone.
