This paper deals with the new emerging technology The Sixth Sense. It's a wearable mobile interface that augments the physical world around us with the digitalised machine world. This technology bridges the gap between the digital world and real world just by allowing the interaction of humans with the machines through simple hand gestures. The category under which this technology falls is the Augmented Reality Technology. This paper eyes on the possible applications and outcomes of such technology and the advantages and drawbacks of the technology after sourcing or implementing it into real world for use. The most important are the technical challenges faced to get succeeded in future and enhancing it more for future and optimal use.

This paper presents the first prototype of an interactive visualisation framework specifically designed for presenting geographical information in both indoor and outdoor environments. The input of our system is ESRI Shapefiles which represent 3D building geometry and landuse attributes. Participants can visualise 3D reconstructions of geographical information in real-time based on two visualisation clients: a mobile VR interface and a tangible AR interface. To prove the functionality of our system an educational application specifically designed for university students is illustrated with some initial results. Finally, our conclusions as well as future
work are presented.

Civic hacking movement, born at the times of Obama campaign, promotes trust in programming code as a new tool able to solve a large variety of public problems usually delegated to public services or dedicated private institutions. Based on a four-year STS-inspired ethnography of " civic hackathons " in France and Russia, the paper aims to draw a profile of a " civic hacker " and grasp the transformations of civic participation brought by this phenomenon. Beyond technoscepticism and solutionism, the author suggests to follow the actors in their work of " putting problems into code " and proposes a pragmatist approach to civic hacking. While recent studies have been critical of civic hacking as part of the broader neoliberal transformations of labor, the author argues that, in the context of distrust towards traditional political institutions and repertoires of contention, civic hacking can assist construction of public problems, and can also mean " hacking the civics " .

Idle time and practices of it are a neglected area in design literature. While work and leisure activities are shaped by laws and political regulations, idle time does not constitute generally accepted practices. However, idle time activities can offer individuals flexibility in their experiences in modern urban life. On the other hand, it also generates times such as waiting moments and traveling time in between everyday activities. In these moments, individuals use their own creativity by the help of “mobile interfaces” to organize their involvement in social relations in unique ways. The purpose of this thesis is to explore idle time activities to develop an understanding about how individuals use idle time to experience their social lives in both physical and virtual environments by using mobile interfaces.

The literature review of this study focuses on foundational concepts on everyday life, psychogeography and symbolic interaction, by taking mobile interfaces and travel into
consideration in public idle times. For this purpose, observations in three different public settings are made. Following that, cultural probe research is conducted to explore what individuals take with them and what they observe in idle time. After cultural probes, I conducted interviews with participants to have a detailed information about what they had filled on the cards.

The thesis concludes with findings and insights on public idle time activities and their interpretations with regard to social, incidental, symbolic and ubiquitous interactions. Briefly, public idle time is framed as active social time in which individuals encounter chance moments and they use their personal creativities to experience pleasant public idle time.

Vision-based approaches for mobile indoor localization do not rely on the infrastructure and are therefore scalable and cheap. The particular requirements to a navigation user interface for a vision-based system, however, have not been investigated so far. Such mobile interfaces should adapt to localization accu- racy, which strongly relies on distinctive reference images, and other factors, such as the phone's

The structural and dynamic properties of the interface during the fcc-bcc transformation in pure iron have been investigated by molecular dynamics simulations. An embedded atom method potential was used for the atomic interactions. Two interfaces, close to the Bain and Kurdjumov-Sachs orientation relations, have been examined during the fcc-to-bcc transformation. In each simulation the system was left to evolve freely at the imposed temperature. In a system with fully periodic boundaries no interface motion has been observed, whereas systems with at least one free boundary do show a mobile interface. After an incubation time, there is a very fast transformation from fcc to bcc, with interface velocities reaching values in the range of 200-700m/s , depending on the interface orientation and on temperature. The characteristics of the transformation are of a martensitic nature, without this being imposed on the system. During the incubation time a complex interface structure is formed, which appears to be essential for the martensitic transformation. From the atomic displacements during the transformation, the occurrence of slip planes can be identified.

The manifestation of quantum behavior in two dimensional electron gases in semiconducting heterostructures and their progressive complexity towards fractional quantum Hall effect went hand-in-hand with the efforts to remove the effect of impurity scattering. For oxide materials, history is repeating itself and to date sample quality is reaching levels where quantum behavior starts to become accessible. To really understand the ground state of two dimensional electron gases in oxide systems, where electron-electron correlation effects seem more important, a step towards modulation doping is necessary, removing dopants away from a conduction channel. We will show that the impurity scattering of a 2DEG at the LaAlO3/SrTiO3 interfaces can be significantly suppressed by defect engineering, allowing the observation of quantum transport in a modulation doped oxide system.

The aim of this work is to explore the use of lightweight but effective user interfaces for mobile navigation and wayfinding in urban environments. Two interactive mobile interfaces were designed and implemented following a user centred approach. The first interface makes use of 2D digital technology such as different representations of 2D maps and textual information. To enhance the user experience during navigation, location aware searches may be performed indicating information about the surroundings. The second interface makes use of virtual reality (VR) and computer graphics to present 3D maps and textual information. The VR maps are also interactive and contain hyperlinks positioned in 3D space which link to either webpages or other multimedia content. Both interfaces allow users to visualise and interact with different levels of representation of urban maps. Initial evaluation has been performed to test the usability of the 2D interface, and limitations of the 2D technology were recorded. To overcome these limitations and explore the potentials of alternative technologies a VR interface was prototyped and a pilot evaluation was conducted.

This paper describes a study that compares the results of usability testing of mobile interfaces based on three different evaluation approaches: (i) using a computer-based mobile phone emulator inside the laboratory (ii) using a mobile phone inside the laboratory (iii) using a mobile phone linked to a wireless camera in the field. The results regarding user performance and usability problem identification showed the existence of more similarities than significant differences between the results of the three evaluation contexts. Moreover, in the simplest evaluation context of the emulator it was possible to identify a large percentage of the overall set of usability problems found.

The contact resistance of field effect transistors based on pentacene and parylene has been investigated by experimental and numerical analysis. The device simulation was performed using finite element two-dimensional drift-diffusion simulation taking into account field-dependent mobility, interface/bulk trap states and fixed charge density at the organic/insulator interface. The width-normalized contact resistance extracted from simulation which included an interface dipole layer between the gold source/drain electrodes and pentacene was 91 kΩcm. However, contact resistance extracted from the simulation, without consideration of interface dipole was 52.4 kΩcm, which is about half of the experimentally extracted 108 kΩcm. This indicates that interface dipoles are critical effects which degrade performances of organic field effect transistors by increasing the contact resistance. Using numerical calculations and circuit simulations, we have predicted a 1 MHz switching frequency for a 1 μm channel length transistor without dipole interface between gold and pentacene. The transistor with dipole interface is predicted, via the same methods, to exhibit an operating frequency of less than 0.5 MHz.

The user interfaces for mobile devices generally have space and entry restrictions. These restrictions often limit both the usage and usefulness of many mobile applications. The Context Reactive User Experience (CRUSE) is a user interface framework enabling the delivery of applications and services to mobile users in a standard usable form. CRUSE is designed to both maximize the amount of

In this paper we propose the use of specific mobile system architecture for navigation in urban environments. The aim of this work is to evaluate how virtual and augmented reality interfaces can provide location and orientation-based services using different technologies. The virtual reality interface is entirely based on sensors to detect the location and orientation of the user while the augmented reality interface uses computer vision techniques to capture patterns from the real environment. The knowledge obtained from the evaluation of the virtual reality experience has been incorporated into the augmented reality interface. Some initial results in our experimental augmented reality navigation are presented.

In this paper, we propose the use of specific system architecture, based on mobile device, for navigation in urban environments. The aim of this work is to assess how virtual and augmented reality interface paradigms can provide enhanced location based services using real-time techniques in the context of these two different technologies. The virtual reality interface is based on faithful graphical representation of the localities of interest, coupled with sensory information on the location and orientation of the user, while the augmented reality interface uses computer vision techniques to capture patterns from the real environment and overlay additional way-finding information, aligned with real imagery, in real-time. The knowledge obtained from the evaluation of the virtual reality navigational experience has been used to inform the design of the augmented reality interface. Initial results of the user testing of the experimental augmented reality system for navigation are presented.

Mobility degradation due to generation of interface traps (Deltamueff(NIT)) is a well-known phenomenon that has been theoretically interpreted by several mobility models. Based on these analysis, there is a general perception that Deltamueff(NIT) is relatively insignificant (compared to Deltamueff due to ionized impurity) and as such can be safely ignored for performance and reliability analysis. Here, we investigate the importance of considering Deltamueff(NIT) for reliability analysis by analyzing a wide variety of plasma oxynitride PMOS devices using both parametric and physical mobility models. We find that contrary to popular belief this correction is fundamentally important for robust and uncorrupted estimates of the key reliability parameters like threshold-voltage shift, lifetime projection, voltage acceleration factor, etc. Therefore, in this paper, we develop a generalized algorithm for estimating Deltamueff(NIT) for plasma oxynitride PMOS devices and systematically explore its implications for NBTI-specific reliability analysis.
