Me à PhD Candidate and Information Officer at the Immersive Education initiative European chapter. My research focused on Intelligent Learning Environments, mixed reality and immersive education. This research is part of a collaborative project between Essex and King Abdulaziz Uni to scale-up existing technology in intelligent environments, from smaller facilities such as the University of Essex iSpace to a complete campus with multi-story large footprint buildings.
Survey conducted by The Economist magazine in 2008 with 289 executives responded the survey, 189 participants came from higher education and 100 came from corporate settings

The interaction between the elements can be defined as Cross-Reality (xReality) or dual reality
The implementation of the InterReality Portal is based on three major components: A real environment A 3d virtual environment xReality objects and Virtual objects
we combine 1) a semi-spherical sectioned screen that includes a desk allowing the user to be sit in a natural position to perform learning activities, with a free-range of head movement without the need of any intrusive body instrumentation, based on a specification from the sci-fi story “Tales from a Pod” 2) a camera that allows students to interact between them and the environment, 3) a network of sensors and actuators to obtain real-time information for object identification and replication for dual reality states.
Following the ideas of smart objects on the Internet-of-Things (IoT), an xReality object has a unique ID, a list of available services (e.g. to get data or receive data) and in some cases rules (e.g. a certain object cannot work without fulfilling some preconditions). In a similar way each virtual object has a unique ID, one or more behaviours attached (e.g. the virtual object must behave as a solid object according to physical variables, such as weight, gravity, etc.) and rules similarly to the xReality object
formed by a group of interchangeable pluggable components, to create a mashup with a main component which identifies and integrates the others
As long as the session continues, changes in any of the objects will be managed by the Context-Awareness agent and the Mixed Reality agent considering the following scenarios: A change in any Virtual object of a given InterReality Portal results in identical changes to all subscribing InterReality portals. A change in an xReality object of a given InterReality Portal results in changes in the representation of the real device on all subscribing InterReality portals.
Learners view: During the learning session when they interact with the environment and between them, they are programming a series of actions to be executed by the objects. Instructors view: While they are creating a UoL, they are establishing a sequence of activities to be performed by the learners during the educational session.
is to built computer science projects combining hardware (xReality objects) and software modules (virtual objects) to create Internet-of-Things applications emphasising computing fundamentals grounded on co-creative and collaborative interaction between learners using problem-based learning (PBL). A diversity of resources may be available to support learning however this process cannot be complete without… IMS = Instructional Management Systems (IMS) Global Learning Consortium BENEFITS à portability and reusability Problem-based learning is a constructionist method that allow students to construct their own knowledge by the correlation between concepts and proposed solutions to real world problems performed in realistic settings
From the instructors’ perspective à the creation of UoL is based on activities (atomic functions) which can be combined to create nuclear functions (a complete UoL). From the learners’ perspective à xReality and virtual objects (atomic functions) can be considered as part of a deconstructed set of components that students can reconstruct in any combination to generate their own unique xReality project – or to reconstruct a xReality project that is prescribed by the instructor – (nuclear functions). From a technical (system architecture viewpoint) à the deconstructed elements become sets of autonomous networked resources, that may be inter-connected to form different combinations (constructed) forming a variety of student projects or UoL as required by the teacher or student.
our research is moving from phase 1 to phase 2, integrating the InterReality Portal implementation with the end-user programming concepts discussed within this paper. The possibility of combining virtual and xReality objects with deconstructionism and the use of end-user programming to create mixed reality learning activities that can be constructed and shared by teams of geographically dispersed students is our final goal.
We presented a series of challenges for constructing this model

BlendedRealityThis might be limited by the capacity of user’s presence and engagement to a single realityat a time (Liftons "Vacancy problem"1) a consequence of the user’s real immersion.9Users interaction in real-time with two differentenvironments (real/localand virtual/distant) extendthem to work as if theywere one, by blendingtraces of one into the otherunconsciously (oftenseemingly as simultaneously).1.
