Panoramic human structure maintenance based on invariant features of video frames

Panoramic photography is becoming a very popular and commonly available feature in the mobile handheld devices nowadays. In traditional panoramic photography, the human structure often becomes messy if the human changes position in the scene or during the combination step of the human structure and natural background. In this paper, we present an effective method in panorama ...

A comparison between experienced and inexperienced video game players’ perceptions

In this article we examine the relationship between usability, hedonic attributes and general appeal of two types of video games, first-person shooters, and massively multi-player online role playing games. Through the use of a successful example of a game from each genre, we examine the perceptions of both inexperienced and experienced players of each game, and draw conclusions on ...

Smart card based time efficient authentication scheme for global grid computing

Decentralization in every walk of life has resulted in the development of Global Grid networking. Data sharing and access depends on their availability, capability, cost and user requirements.

Social design feedback: evaluations with users in online ad-hoc groups

Social design feedback is a novel approach to usability evaluation where user participants are asked to comment on designs asynchronously in online ad-hoc groups. Two key features of this approach are that (1) it supports interaction between user participants and development team representatives and (2) user participants can see and respond to other participants’ comments. Two ...

Automatic evaluation technique for certain types of open questions in semantic learning systems

In this paper, we propose a methodology to enhance the evaluation tools in semantic learning systems. Our proposal’s aim is to evaluate two types of open questions in hybrid exams. The proposed technique in the first type MOQ (Multi Operations Question) uses the matrix concept for fuzzy score. But POQ (Proof Open Question) is more complicated so we use direct connect to learning ...

A framework to integrate speech based interface for blind web users on the websites of public interest

Despite many assistive tools available for browsing the web, blind persons are not able to perform the tasks using internet that are done by persons without such disability. Even the futuristic social networking sites and other websites using the features of web 2.0 indicate a lesser accessible/responsible web. In this paper, we propose a framework, which can be used by the ...

The art of software systems development: Reliability, Availability, Maintainability, Performance (RAMP)

The production of software systems with specific demand on reliability, availability, maintenance, and performance (RAMP) is one of the greatest challenges facing software engineers at all levels of the development cycle. Most requirements specification tools are more suited for functional requirements than for non-functional RAMP requirements. RAMP requirements are left ...

Performance evaluation of data aggregation for cluster-based wireless sensor network

In wireless sensor network, data fusion is considered an essential process for preserving sensor energy. Periodic data sampling leads to enormous collection of raw facts, the transmission of which would rapidly deplete the sensor power. In this paper, we have performed data aggregation on the basis of entropy of the sensors. The entropy is computed from the proposed local and ...

Collective intelligence within web video

We present a user-based approach for detecting interesting video segments through simple signal processing of users’ collective interactions with the video player (e.g., seek/scrub, play, pause). Previous research has focused on content-based systems that have the benefit of analyzing a video without user interactions, but they are monolithic, because the resulting key-frames are ...

Intention awareness: improving upon situation awareness in human-centric environments

As the gap between human and machine shrinks, it becomes increasingly important to develop computer systems that incorporate or enhance existing Situation Awareness. However, these tend to focus on raw quantitative parameters, such as position and speed of objects. When these situations are governed by human actors, such parameters leave significant margins of uncertainty. In this ...

Incremental development & revolutions of E-learning software systems in education sector: a case study approach

Advancement in the area of software engineering, mobile computing together with web technologies have paved way for myriad range of applications, including good quality E-learning software’s, delivering online classes in real time to unlimited number of students across the world, on a personalized E-learning space for every student. These E-learning software systems have virtually ...

Generating metadata from web documents: a systematic approach

In this paper, a mechanism generating RDF Semantic Web schema from Web document set as the semantic metadata is proposed. Analyzing both the structural and un-structural content of Web documents, semi-structured Web documents can be conceptualized as resource objects with inter-relationships in RDF diagram. Technically, hyperlinks, basic annotations, and keywords in web documents ...

Shared virtual presentation board for e-Meeting in higher education on the WebELS platform

In this paper, the development of a shared virtual presentation board (VPB) for real-time e-Meeting on the Web-based e-Learning System (WebELS) platform is introduced. WebELS is a general-purpose e-Learning system to support flexibility and globalization of higher education in science and technology. In WebELS, the Meeting module consists of online presentation and video conference ...

WordBricks: a virtual language lab inspired by Scratch environment and dependency grammars

This paper explains design decisions forming a foundation of WordBricks — an intelligent computer-assisted language learning environment, recently initiated at our institution. WordBricks is intended to serve as a “virtual language lab” that supports open experiments with natural language constructions. Being based on dependency grammars, this instrument illustrates the use of ...

ETSI compliant GeoNetworking protocol layer implementation for IVC simulations

Inter-Vehicle Communication (IVC) is an important component of the ITS architecture, that enables Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. GeoNet project brought the IVC one step further by enabling transparent IP connectivity between vehicles and the infrastructure. Specifications produced by the GeoNet project have been incorporated into ...

Artificial neuro fuzzy logic system for detecting human emotions

This paper presents an adaptive neuro/fuzzy system which can be trained to detect the current human emotions from a set of measured responses. Six models are built using different types of input/output membership functions and trained by different kinds of input arrays. The models are compared based on their ability to train with lowest error values. Many factors impact the error ...

Enhancing Wi-Fi fingerprinting for indoor positioning using human-centric collaborative feedback

Position information is an important aspect of a mobile device’s context. While GPS is widely used to provide location information, it does not work well indoors. Wi-Fi network infrastructure is found in many public facilities and can be used for indoor positioning. In addition, the ubiquity of Wi-Fi-capable devices makes this approach especially cost-effective. In recent years, ...

Publishing and discovering context-dependent services

In service oriented computing, service providers and service requesters are main interacting entities. A service provider publishes the services it wishes to make public using service registries. A service requester initiates a discovery process to find the service that meets its requirements using the service registries. Current approaches for the publication and discovery do not ...

An indoor augmented-reality evacuation system for the Smartphone using personalized Pedometry

There currently exist widely used mobile phone emergency applications for the smartphone and limited mobile emergency applications for indoor environments. However, the outdoor applications only focus primarily on providing accident information to users, and the indoor applications are limited by the unavailability of GPS user-positioning and by WiFi-based access problems.
