Mobile Outdoor Augmented Reality
Tout le monde est connecté.
Comment faire pour mélanger réel et virtuel ? Quels en seraient les avantages, les potentiels, les dangers ? A-t-on besoin du hardware ? Beaucoup de questions pour le futur du Wired, pardon du Net. Certains tentent d’y répondre :
Augmented reality (AR) is the registration of projected computer-generated images over a user’s view of the physical world. With this extra information presented to the user, the physical world can be enhanced or augmented beyond the user’s normal experience. The addition of information that is spatially located relative to the user can help to improve their understanding of it.
We have written a number of applications which use Tinmith technology in order to perform outdoor augmented reality tasks. The Tinmith-Metro application is our main application, demonstrating the capture and creation of 3D geometry outdoors in real time, leveraging the user’s physical presence in the world.
The first example is what we call street furniture. The user can place down objects such as trees, tables, light posts, and other outdoor items. Using the gloves, the user can manipulate these objects into the correct position, and then scale and rotate them as well. This application is useful for performing landscape gardening type tasks, and allows designers to place down objects, and see what they look like in the environment before using a real shovel and purchasing real items.
The second example is what we call construction at a distance. Using this technique, the user can place down simple primitives (such as large planes) and use these to form the shapes of buildings, either existing already, or creating them from scratch. Once these primitives are in place, users can perform carving operations and texture mapping to increase the complexity of the model. This technique can be used to model structures such as buildings, automobiles, and trees.
By combining these operations with street furniture, it is possible to build complete worlds, either to model the existing world, or to create new worlds from scratch. For existing buildings, builders and architects can capture the geometry of existing buildings, and then make modifications to see what they will look like in the real world. For new buildings, designers can walk around outside creating objects, and then show them to potential customers before having to physically build any objects. The customer can then make changes and observe these in real time to build the perfect house and garden, and see these in the exact real world location.
We have been developing these AR systems since 1998. Our first backpack systems were large, fragile, bulky, and showed primitive images due to the technology available.
Effectivement un peu encombrant. En tout cas ça ressemble BEAUCOUP au matériel que porte l’aspirant Knight dans le layer #7 de Serial Experiments Lain
The whole new system weighs 4 kilograms. Battery packs are an additional weight of approximately 2-4 kg depending on operating time and battery technology used. The profile of the system is almost to the point where a large jacket could be worn over the top and conceal it.

Bien entendu certains vont dire « ouais mais tant qu’il y aura pas Quake sur ce système ce sera du temps perdu. » Enfin bon franchement comment voulez-vous que… Oh !… Attendez… Vous avez dit Quake ?.
We modified the iD software version of Quake to work on a mobile AR computer. Using a GPS, orientation sensor, and a plastic gun, users can walk around in an outdoor environment playing Quake.

We have built prototype systems that have been used for mining visualisation, military simulation, agriculture visualisation, and entertainment.
User’s can also use what we term ‘god-like techniques’ to communicate with people outdoors.
