	~~While most~~ location based information streams ~~are now~~ reality ~~and are available for use,~~ Augmented reality is currently ~~still under research or with few commercial or professional uses~~.		The information provided by location based information streams can be presented to the user using augmented reality. Augmented reality consists in enhancing real-world environments with information that can be superimposed on the images<ref>[[Wikipedia:Augmented reality\|Augmented reality on Wikipedia]]</ref>. This technology was originally used in the [[SKYbrary:Head Up Display\|head-up displays of aircraft]]<ref>[[SKYbrary:Head Up Display\|Head-up display on SKYbrary]]</ref> and in some luxury cars<ref>[[Wikipedia:Head-up display\|Head-up display on Wikipedia]]</ref> and is currently being used on mobile devices to display additional information over the image being captured.

	Augmented reality consists in enhancing real-world environments with information that would be superimposed on real-world images. This technology is already used in the [[SKYbrary:Head Up Display\|head-up displays of aircraft]]<ref>[[SKYbrary:Head Up Display\|Head-up display on SKYbrary]]</ref>. and some luxury cars<ref>[[Wikipedia:Head-up display\|Head-up display on Wikipedia]]</ref>.		The combination of LBS and augmented reality technologies allows to have information about the surrounding of the user superimposed in real-world images. The image captured, positioning information and the inertial sensors information of the devices are used to determine the position and orientation of the device and the digital artefacts are superimposed over the image in a realistic way. Augmented reality provides a blending reality with the additional location based information that the user requires in a seamless and intuitive way<ref name="lbs_found"/>.

	The combination of LBS and augmented reality technologies ~~would allow~~ to have information about the surrounding of the user superimposed in real-world images. ~~Such images could be~~ captured ~~by cell-phone cameras or by~~ the ~~use~~ of ~~special glasses providing~~ a blending of reality with the additional location based information that the user requires<ref name="lbs_found"/>.

	There are 2 main variants of this kind of applications<ref name="lbs_found">[http://citeseerx.ist.psu.edu/viewdoc/download;jsessionid=DC7731148ED00DA3D7BCEF659F699801?doi=10.1.1.94.1844&rep=rep1&type=pdf Foundations of Location Based Services], Lecture Notes on LBS, Stefan Steiniger, Moritz Neun and Alistair Edwardes, CartouCHe</ref>:		There are 2 main variants of this kind of applications<ref name="lbs_found">[http://citeseerx.ist.psu.edu/viewdoc/download;jsessionid=DC7731148ED00DA3D7BCEF659F699801?doi=10.1.1.94.1844&rep=rep1&type=pdf Foundations of Location Based Services], Lecture Notes on LBS, Stefan Steiniger, Moritz Neun and Alistair Edwardes, CartouCHe</ref>:
	* '''Pull Services''': The user uses the mobile application to request information based on its location. Examples of these applications are applications where the user requests the nearest [[Wikipedia:Automated teller machine\|ATM]]s and the information server responds with a list of the closest ones, eventually with navigation instructions to get there.		* '''Pull Services''': The user uses the mobile application to request information based on its location. Examples of these applications are applications where the user requests the nearest [[Wikipedia:Automated teller machine\|ATM]]s and the information server responds with a list of the closest ones, eventually with navigation instructions to get there.
	* '''Push Services''': The position of the user is monitored by the information server and when the user position triggers determined conditions (such as entering a determined area) the information is sent automatically to the user. Normally the user activates the services and normally can configure the conditions in which information is pushed to his device. These services might require that an application is kept running in the background feeding the user position to the information server. Examples of such applications are advertising applications that send discount coupons to users in the proximity of a store.		* '''Push Services''': The position of the user is monitored by the information server and when the user position triggers determined conditions (such as entering a determined area) the information is sent automatically to the user.

	This kind of services can raise privacy concerns, especially Push Services since the user position might be shared with third-parties without consent. To protect the user from this, some countries have passed legislation to guarantee that the user's position is only used with consent and that no messages are sent unless the service is explicitly activated<ref name="lbs">[[Wikipedia:Location-based service\|Location-based Services on Wikipedia]]</ref>.
