Nature of Adaptivity
Adapt the presentation based on learnercharactistics
Divides into two main mechanisms:Link-level Adaptivity, (Navigational)Link-level Adaptivity, (Navigational)
Content-level Adaptivity
Canned Text Adaption, (Brusilovsky,2001)
Can be used with segments of AV material
Requires splitting up content into objects

Learning Objects (Segments)
any entity, digital or non-digital, which canbe used, re-used and referenced duringtechnology-supported learning
Based on a learning objective or goalBased on a learning objective or goal
Allows Re-use, (depending on context)
Allows content to be wrapped in additionalinformation, (meta-data)
Allows accurate linking

We modified the layout of the digitalworld in Blender. We exported thedigital world to Vizard file format.We used 3D Studio Max and

We used 3D Studio Max andSoftimage|XSI with FBX plug-ins for3D modelling. 3D Studio Max has abuilt in exporter for .FBX formatwhich MotionBuilder reads. InMotionBuilder, we set up the rig ofthe character and applied theMotion-Capture (mocap) animationonto the character's skeleton. Theanimation footage is produced byVizard Virtual Reality software.

Augmented Reality
Imagine a VR head mounted display,
but the display doesn't block out the regular view,it's just superimposed on it.
Imagine walking around a building and "seeing" inside Imagine walking around a building and "seeing" insidethe walls to the wiring, plumbing, and structure.
Or, seeing the tumor inside a patient's head as you hackaway at it.

Extra information is displayed on a HMD Currently mainly used in the military with few civilian
applications

MARS: MobileAugmented Reality Systems
In the Touring Machine scenario, the MARS unit acts as a campus information system,
assisting a user in finding places and allowing her to queryinformation about items of interest, like buildings, statues,etc.

The Layar Reality Browser An augmented reality app
(mobile phone application) that
shows you what is around you by displaying real timedigital information (layers) on top of reality.digital information (layers) on top of reality.
This digital information is called a ‘layer’.
Layers can provide services, such as finding ATMs,houses for sale and restaurants including reviews.
Layers can also provide an experience with interactivity,3D objects and sounds for games and engaging guidedtours. Many layers provide both.

AR platform? Essentially you’re using your phone like a
camera
so you can see the real world as you pan around,but the application utilizesbut the application utilizes
your GPS location and G-Sensor to determineexactly what your phone/camera is pointingtowards and
provides you more information about it directly onyour phone!
But Layar technology isn’t just an application…its a platform.

Imagine that:
Signs could broadcast their message in severallanguages, being automatically picked up and displayedon the users phone in the appropriate language.on the users phone in the appropriate language.
A map with GPS and/or building information could beprojected on to the phone –> No more getting lost.
Virtual tour guides could be downloaded for any countryand location.
Multimodal support for visual-impaired, using brail…
The possibilities are endless…
