Augmented reality (AR),  comprises the overlay of information on real-world views seen through a camera. 

One common definition of augmented reality states that an augmented reality system

has to fulfill the following requirements (Henrysson 2007):

• It combines the real and the virtual

• It is interactive in real time

• It is registered in three dimensions

Augmented reality can be used for many different things. For example, one AR application could allow users to point their phone's camera at a building, click on an information label associated with the building and see information about the building's history.Augmented reality opens up a lot of possibilities for new types of games, where the real and the virtual world are mixed.  In recent years, mobile phones have become more and more powerful, and since many of them have built-in cameras and rather large screens, they are a potential platform for augmented reality games.

Mobile phone that is suitable for augmented reality games  often has  a number of features that could be used in such a game.

Some of them are:

   • Multi-touch

• GPS

• An accelerometer

• A relatively large screen (3.5 inches or bigger)

• A 5.0 megapixel camera

Here’s a list of several popular Augmented Reality mobile games found on the web.

1. AR Defender

2. AR! Pirates

3. ARBasketball

4. ARSoccer

5. Star War

These exmaples have shown the potentials of creating AR  games on mobile phone.  Our research interests

will be to explore what possibilities and problems come with the creation of augmented reality games for mobile phones. Some of chosen research questions are these:

1

What are some of the possibilities and problems associated with the creation of

augmented reality games for the mobile phone?

2

How could the different sensors on mobile phone be used to enhance an augmented reality

game?

3

What restrictions does the mobile Phone's hardware and software put on an augmented

reality game?  

4 How suitable is the mobile phone  as a platform for augmented reality gaming?
