Mobile attack approaches can be categorized as Application Based Attacks and Frequency Based Attacks. Application based attacks are reviewed extensively in the literature. However, frequency based attacks to mobile phones are not experimented in detail. In this work, we have experimentally succeeded to attack an Android smartphone using a simple software based radio circuit. We have developed a software...
We designed and created a new video database that models a variety of complex distortions generated during the video capturing process on hand-held mobile capturing devices. We describe the content and characteristics of the new database, which we call the LIVE Mobile In-Capture Video Quality Database. It comprises a total of 208 videos that were captured using eight different smart-phones and were...
Precise reconstruction of 3D volumes from X-ray projections requires precisely pre-calibrated systems where accurate knowledge of the systems geometric parameters is known ahead. However, when dealing with mobile X-ray devices such calibration parameters are unknown. Joint estimation of the systems calibration parameters and 3d reconstruction is a heavily unconstrained problem, especially when the...
Exergames combine exercising with game play by requiring the users to perform some kind of physical activity (and exercise) in order to score points in the game. In this paper, we present mobile exergames that are affordable, fun, ubiquitous, and most importantly portable allowing the players to carry exergames with them wherever they go. Our mobile exergames need two pieces of portable equipment...
We introduce a novel method for creating mobile applica-tions, integrating the Android SDK into PlayGo, a scenario-based behavioral programming framework. The method al-lows creating mobile applications simply by using a visualGUI editor, and then incrementally “playing in” scenariosthat construct the application’s behavior. This allows thedeveloper to focus on the behavior and interface rather thanon...
This paper deals with a design of specific marker detector and tracker for semiautonomous convoy purpose. The solution is based on computer vision. The detectors main requirement is the specific marker recognition ability for various environments. The next part of this paper deals with tracking of marker by KLT algorithm. This solution was primary designed for a semi-autonomous convoy task, where...
This work presents a video surveillance platform for smart cities designed to exploit the facilities offered by SDN/NFV networks to achieve gain in terms of scalability, flexibility, OpEx and CapEx reduction. The main elements of this platform are the Smart Access Nodes (SAN) and the Network Access Nodes (NAN). SAN devices are distributed on the territory to cover small/medium areas and provide connectivity...
While we witness significant changes in display technologies, to date, the majority of display form factors remain flat. The research community has investigated other geometric display configuration given the rise to cubic displays that create the illusion of a 3D virtual scene within the cube. We present a self-contained mobile perspective cubic display (mpCubee) assembled from multiple smartphones...
We present a demonstration of HeadPhones (Headtracking + smart-Phones), a novel approach for the spatial registration of multiple mobile devices into an ad hoc multi-display environment. We propose to employ the user's head as external reference frame for the registration of multiple mobile devices into a common coordinate system. Our approach allows for dynamic repositioning of devices during runtime...
Most research on the visual servoing of mobile manipulators used the assumption that the depth information is already known. In this paper, a visual servoing scheme without the prior knowledge of depth is proposed to regulate a mobile manipulator to a desired pose at eye-to-hand setup. To deal with the nonholonomic constraint of wheeled mobile platform, the Jacobian matrix was combined with the depth-independent...
This paper develops a multi-user streaming feedback system for cooperative learning in classroom learning. The system offers Android Apps to perform mobile interactive learning. Therefore, the system can be applied for interactive teaching. It also provides a game-based approach to improve students' cooperative learning. On the cognitive development of the game-based learning, the students use mobile...
The growing interest for mobile biometrics stems from the increasing need to secure personal data and services, which are often stored or accessed from there. Modern user mobile devices, with acquisition and computation resources to support related operations, are nowadays widely available. This makes this research topic very attracting and promising. Iris recognition plays a major role in this scenario...
The ubiquitous hand gesture plays an important role in the natural human machine interaction (HMI). Recently, the consumer color and depth cameras have been used to estimate hand shapes and postures for the mid-air HMI. Under the observation that 3D hand contours possess much information of hand postures, we estimate 3D hand contours from infrared images with a limited computation complexity for the...
In this paper, we study full-view coverage in camera sensor networks, by exploiting their limited mobility of orientation rotation. We focus on the fairness based coverage maximization problem, i.e., how to schedule the orientations of the camera sensors to maximize the minimum accumulated full-view coverage time of target points. To solve this problem, we first try to reduce the space dimension of...
Testing with final users allows evaluators to detect failures and problems that were not considered during the design and the different stages of development of an application or a web site. In order to be able to perform those tests is important to create an environment where user's responses, reactions and opinions while interacting with an application or a web site can be analyzed. A usability...
Vision measurement technology research is active in recent years, which has broad application prospect in the fields of military and civilian industrial production. On the basis of comparing several existing measurement techniques, our paper mainly studied a method of geodetic coordinate calculation based on monocular vision on UAV platform, which is extension and expansion of the traditional monocular...
At crowded events, an increasing number of people use their mobile devices at the same time to run applications having high data requirements leading to network congestion. This paper investigates the use of LED light to act as a Li-Fi source in order to transmit data. The data is captured using the CMOS camera of an Android smartphone. The experimental setup is tested using two different Android...
Due to advancement in minimization and mass-production, cameras are ubiquitously embedded in most of current mobile devices including phones, vehicles, robots, and augmentedreality displays. These mobile cameras are cheap and can gather in real-time large amounts of streaming data about the surrounding environment. Using an information-theoretic model of a streaming video captured by a mobile camera,...
A mobile flying projector is hard to build due to the limited size and payload capability of a micro aerial vehicle. Few flying projector designs have been studied in recent research. However, to date, no practical solution has been presented. We propose a versatile laser projection system enabling in-flight projection with feedforward correction for stabilization of projected images. We present a...
The current paper presents the Quiz Cube application and its evaluation. The Quiz Cube application is an AR mobile learning application for students and teachers to easily make and use AR UI system using fiducial marker cubes. AR as a platform is just now reaching its full potential. Since smartphones and mobile devices are now at a sufficiently large user base, it is worth looking at the potential...
