Virtual Reality (VR) is a three dimensional interactive world that gives users the impression of being somewhere other than where they actually are. Over the last decade, a wide range of VR applications have been developed, based on VR environments. Immersive VR environment is a type of VR environment that produces an interactive computer generated world of high ecological validity, in which the users can "immerse" themselves using a variety of 3D stimuli. On the other hand, non-immersive VR environment is the least immersive implementation of VR techniques in which the virtual environment is viewed through a portal or window by utilizing a standard high resolution monitor and interactions occur using 2D interaction devices such as keyboards and mice. A major limitation of non-immersive VR environments is the lack of immersive experience that not only provides content to users, but also enables them to interact in a completely 360 degree immersive environment. Furthermore, a knowledge gap exists in terms of what motivates individuals to utilize such systems. This thesis aims to fill these research gaps by first i) exploring whether there exists statistically significant differences in performance between users in immersive VR and non-immersive VR environments and then ii) proposing the use of video game design elements in non-game contexts (i.e., immersive VR environments) to motivate and increase user engagement, otherwise known as "gamification". A case study involving 54 individuals carrying out a product functional analysis task is used to test the hypothesis that immersive VR environments, such as those achievable through head-mounted displays, enhance performance outcomes when compared to non-immersive VR environments. A case study involving 60 games from the Android market is used to understand the fundamental aspects of video games that make them engaging and motivating. Seven game design elements (challenges, levels, win states, social graph, rewards, content unlocking and leaderboards) are found to motivate users and maintain user engagement for extended periods of time and could be potentially integrated into immersive VR environments to make them more engaging and motivating for users.

Strengthen your understanding of the persuasive mechanisms used by terrorist groups and how they are effective in order to defeat them. Weaponized Words applies existing theories of persuasion to domains unique to this digital era, such as social media, YouTube, websites, and message boards to name but a few. Terrorists deploy a range of communication methods and harness reliable communication theories to create strategic messages that persuade peaceful individuals to join their groups and engage in violence. While explaining how they accomplish this, the book lays out a blueprint for developing counter-messages perfectly designed to conquer such violent extremism and terrorism. Using this basis in persuasion theory, a socio-scientific approach is generated to fight terrorist propaganda and the damage it causes.

"This thesis aim to test the effectiveness of an immersive virtual reality set-up by using an embodied virtual body in neurorehabilitation, specifically for motor and chronic pain disorders. More specifically, my first study entitled: Motor-cognitive training through Immersive Virtual Reality during the immobilization period in distal radius fracture patients, aims to investigate whether an upper limb immersive virtual reality (IVR) training program, may improve the motor and functional ability of a fractured arm in 54 distal radius fracture (DRF) patients during the immobilization period. With this intention, we compared 6 weeks of our IVR training group (n=20), with 6 weeks of a non-IVR training group (n=20), and with another conventional rehabilitation group (n=14), during the immobilization period. We observed that through our training program patients in the IVR training group reached a better motor-functional ability of the fractured arm after cast removal, compared to the patients in the control groups: non-immersive virtual reality group and conventional rehabilitation group. Finally, patients in the IVR training group presented better results in the follow-up (6 weeks later) compared to the control groups, especially in the wrist range of motion. Secondly, we wanted to investigate the effects of the upper limb IVR training program in chronic stroke patients without arm mobility with a case study: Using immersive virtual reality to rehabilitate the paretic upper limb in chronic stroke patients. In that case study, we tested the IVR program in three chronic stroke patients. To this aim all three chronic stroke patients, underwent two IVR training periods during 5 weeks every day, with a 3 weeks period of pause between the two training periods. After the first training period we found improvements in motor recovery of the paretic arm, as well as in the cognitive capability and quality of life of all three chronic stroke patients. Further, we observe that the motor-cognitive improvements obtained after the first IVR training period remained over time, during the period of pause. However, the second IVR training period was not effective to further enhance motor and cognitive improvements. Further, a pre-post brain imaging analysis by using resting state and diffusor tension imaging (DTI) techniques, allowed us to identify the underpinning neuroplastic changes following the first IVR training, that were mainly found at the cerebellum from a functional connectivity point of view, and in the primary motor cortex from an structural point of view, in all three chronic stroke patients. Finally, the last study of this thesis entitled: Immersive virtual reality reliefs pain in patients with complex regional pain syndrome type I but not with peripheral nerve injury, aimed to investigate whether varying properties of a virtual arm co-located with the real arm modulated pain ratings in patients with chronic arm/hand pain due to complex regional pain syndrome (CRPS) type I (without nerve injury) or peripheral nerve injury (PNI). CRPS (n=9) and PNI (n=10) patients were immersed in VR and the virtual arm was shown at four transparency levels (transparency test) and three sizes (size test). We evaluated pain ratings throughout the conditions and assessed the virtual experience, finding that patients with chronic pain can achieve levels of ownership and agency over a virtual arm similar to healthy participants. All seven conditions globally decreased pain ratings to half. Increasing transparency decreased pain in CRPS but did the opposite in PNI, while increasing size slightly increased pain ratings only in CRPS. In overall my doctoral thesis pave the way to the use of embodiment through an IVR set-up in neurorehabilitation following the principles of body illusions for rehabilitation." -- TDX.

There has been an evolution of the explanations on the results of research on human learning and how digital technologies have supported the design of more efficient learning environments. Previous theories such as Richard Mayer’s cognitive theory of multimedia learning and John Sweller’s cognitive load theory have gained signification attention and remain the two main theories within the multimedia learning field. However, there has not yet been a book compiled of several investigations on the specific 4C-ID model that covers different domains of knowledge. The 4C-ID model combines the two main theories of Richard Mayer and John Sweller to advance the field of learning and instruction. 4C-ID Model and Cognitive Approaches to Instructional Design and Technology: Emerging Research and Opportunities explores the behavioral and constructivist approaches to learning and instruction and focuses mainly on the particular cognitive approach and resulting theories and insights of the 4C-ID model. The chapters present the results of three experimental studies applied to the teaching of electrical circuits, initiation to computer programming using the Alice microworld, and computer programming using Python textual language. This book is a valuable resource tool for computer programmers, computer scientists, teachers, educational psychologists, practitioners, researchers, academicians, and students interested in the various approaches to learning and instruction in terms of the 4C-ID instructional model.

We will be, sooner or later, not only handling personal computers but also mul- purpose cellular phones, complex personal digital assistants, devices that will be context-aware, and even wearable computers stitched to our clothes...we would like these personal systems to become transparent to the tasks they will be performing. In fact the best interface is an invisible one, one giving the user natural and fast access to the application he (or she) intends to be executed. The working group that organized this conference (the last of a long row!) tried to combine a powerful scientific program (with drastic refereeing) with an entertaining cultural program, so as to make your stay in Rome the most pleasant one all round: I do hope that this expectation becomes true. July 2005 Stefano Levialdi, IEEE Life Fellow INTERACT 2005 General Chairman [1] Peter J. Denning, ACM Communications, April 2005, vol. 48, N° 4, pp. 27-31. Editors’ Preface INTERACT is one of the most important conferences in the area of Human-Computer Interaction at the world-wide level. We believe that this edition, which for the first time takes place in a Southern European country, will strengthen this role, and that Rome, with its history and beautiful setting provides a very congenial atmosphere for this conference. The theme of INTERACT 2005 is Communicating Naturally with Computers.
