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...
Most embedded systems require contiguous memory space to be reserved for devices, which may lead to memory under-utilization. Although several approaches have been proposed to address this issue, they have limitations of either inefficient memory usage or long latency for switching the reserved memory space between a device and general-purpose uses. Our scheme, on the other hand, utilizes reserved...
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...
This paper provides a substation live working robot system, which consists of mobile insulation lift platform, six degree of freedom hydraulic manipulator, master control system and live working tools. It can assist or replace the manual to complete some special live-working, such as insulator cleaning, RTV spraying, Insulator detection, Nitrogen flushing. The successful application of the robot provides...
This work describes a method to extend classical maps in terms of additional information and a prediction about objects within the environment. The prediction system is based on the behaviour of the observed objects and influences accordingly the updating of the map. First all objects are classified due to their size and further parameters characterizing the ability to move. Furthermore the velocity...
The purpose of this paper is to illustrate an Internet of Everything based integrated security system for archaeological areas capable of ensuring visitors security, cultural heritage preservation/protection and great usability for visitors, with particular reference to visitors with disabilities. Genetic Algorithms (GAs) have been used to design the integrated security system, in particular for fields...
There is a growing number of incidents related to using cell phones while walking on the street. To address this issue, this paper proposes a new system based on tactile paving detection on the sidewalk to alert distracted mobile users to avoid traffic hazard. Our system (namely Inspector) is deployed as an application on an off-the-shelf normal mobile phone equipped with back camera. Inspector plays...
Dipstick-based urinalysis is routinely used for detection of early signs of such pregnancy complications, as preeclampsia and gestational diabetes. Usually it is done in doctor's office using an automatic dipstick analyzer. Here we present a novel smartphone-based colorimeter and demonstrate its application to the measurements of glucose and protein concentrations in biological samples. The key innovations...
