We designed an interactive digital signage (IDS) system for use in advertising. The system is characterized by visual content (images, videos, and texts) provision on a large display for interacting with mobile phones. Its principal feature is that it enables users to easily perform tasks such as making restaurant reservations and televoting. It is also applicable to fixed mobile convergence (FMC)...
Within the EU FP7 project FascinatE, a capture, production and delivery system capable of allowing end-users to interactively view and navigate around an ultra-high resolution video panorama showing a live event is being developed. Network-based processing is used to repurpose the content to suit delivery towards different device types and user selection of regions of interest. In this paper we report...
Rapid growing of internet applications and users has led the improvement of mobile web browser technology and standards such as HTML5. Recently, HTML5 is turning to be a de facto standard after some of its features has been implemented in major mobile web browsers. Moodle as a web based Learning Management System (LMS) has been popular in academic environment for supporting learning activities and...
The biggest change in the mobile market in the coming years will not happen at the top consumer level where high end mobile devices will be equipped with the latest multimedia tools but at the untapped market of about one billion people in the mid segment of the world economic pyramid whose potential to become profitable telecom customers has been underestimated and misunderstood. In the Rural Living...
This paper presents an application for collaborative design of mobile prototypes, covering both prototyping and evaluation stages of design. Virtual design workspaces provide designers with the necessary mechanisms to build and test prototypes. Shared versions of these workspaces along with annotation mechanisms offer the ability to not only constitute collaborative design groups, but also perform...
The wireless communication between small handheld devices can be easily eavesdropped by unauthorized devices. Hard restrictions in computing power and energy consumption favour symmetric key methods to encrypt the communication of small mobile devices. Symmetric encryption imposes questions on effective and user-friendly unobtrusive ways for key distribution. Instead of distributing or exchanging...
Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
3D contactless technology based on capacitive coupling represents a promising solution for high-speed and low power signaling in vertically integrated chips. AC coupled interconnects do not suffer from mechanical stress, and the parasitic load is much reduced when compared to standard DC solutions, such as wire bonding and micro bumps. Communication system based on wireless interconnection scheme...
