Quick Abstract

In this paper we describe a new tool for interactive presentations: the speaker shows a common slideshow on the screen, and the users can see the same slide in their smartphone or tablet, independently from its model and brand. The system can be used for both on-line and on-site presentations and encourages the user to perform social activities, e. g., comment or like a slide. The author can also submit a questionnaire or a poll to the audience and see in real-time the answers. Our tool has been used during 37 different events, followed by 3753 users. We recorded the actions of the users and, depending on the different kind of events, the average of actions ranges from 1 to 8 per user per presentation. This data shows that our tool helps to increase users engagement and to maintain user attention.

Evaluating Impact of Cross-platform Frameworks in Energy Consumption of Mobile Applications

Topics: Web Services and Web Engineering; Context-Awareness; Context Detection; Mobile APIs and Services

Authors: Matteo Ciman and Ombretta Gaggi

Affiliation: University of Padua, Italy

Digital Object Identifier: 10.5220/0004857604230431

Proceedings of WEBIST 2014, ISBN: 978-989-758-023-9

Quick Abstract

In this paper we analyze energy consumption of mobile applications using different smartphones sensors, e.g., GPS, accelerometer, etc., and features, e.g., acquiring video or audio from the environment. In particular, we have studied how the use of frameworks for mobile cross-platform development may influence the amount of required energy for the same operation. We use an hardware and software tool to measure energy consumption of the same application, using different sensors, when developed natively or using two frameworks, Titanium and PhoneGap. Our experiments have shown that frameworks have a significant impact on energy consumption which greatly increases compared to an equal native application. Moreover, the amount of consumed energy is not the same for all frameworks.

Tactive, a Framework for Cross Platform Development of Tabletop Applications

Topics: Web Services and Web Engineering; Personalized Web Sites and Services; Multimedia and User Interfaces; Web Programming

Authors: Ombretta Gaggi ¹ and Marco Regazzo ²

Quick Abstract

The number and types of applications developed for multi-touch tabletops are dramatically increased in the last years, mainly due to the fact that interactive tabletops allow a more natural interaction with the user through their multi-touch interfaces. Despite many applications share a big set of common features, e.g., gestures recognition, interface orientation, etc., almost all applications implement their home made software solutions. In this paper we present Tactive, a software layer for fast development of portable applications for multi-touch interactive tabletops. Tactive allows to abstract from hardware and software equipment and to embed a web application into a application for multi-touch surfaces. Our framework supports up to five fingers gestures recognition and communication between different windows, and allows to save more than 60% of developing time.

Quick Abstract

CVI (Cerebral Visual Impairment) is the leading cause of visual impairment in the United States and the Western Europe. Due to the high number of different inabilities that children could have when affected by CVI, it is crucial for the rehabilitation process to start from a good assessment, especially at early ages. In this paper we present HelpMe!, a serious game to improve the rehabilitation process for these children with a system able to adapt the exercises to each particular child and to his/her improvements. The system integrates an eye tracker system to correctly measure the performances of the child and his/her capability to watch and touch a moving object at the same time.

Proceedings of SIGMAP 2012/ICETE, ISBN: 978-989-8565-25-9

Quick Abstract

This paper presents SMIL PhotoShow, an authoring tool for photo books, which allows the creation of enhanced multimedia presentations, enriched with audio (music or spoken) comments, transition effects and animations in a very simple way. Our tool allows to create a digital counterpart of a printed photo book with the aim to bridge the gap between digital web albums and printed photo books. Since authoring a photo book is a time consuming activity, SMIL PhotoShow provides the users also the possibility to create, with only three clicks, an engaging slideshows with transition effects and background music.

TOWARD THE CREATION OF A GREEN CONTENT MANAGEMENT SYSTEM

Topics: XML and Data Management; Web Services and Web Engineering; Accessibility Issues and Technology; Personalized Web Sites and Services

Authors: Matteo Ciman , Ombretta Gaggi and Marco Sbrignadello

Affiliation: University of Padua, Italy

Digital Object Identifier: 10.5220/0003340204080412

Proceedings of WEBIST 2011, ISBN: 978-989-8425-51-5

Quick Abstract

In this paper we discuss the problem of efficient use of Content Management Systems in the development of a web site, and we propose a new approach towards the definition of a Green Content Management System (GCMS). Our GCMS distinguishes between pages which contain dynamic data and pages which are not supposed to change frequently. This second kind of documents is generated, off-line, every time that a change occurs, thus avoiding waste of CPU time, and improving the response time of pages. For this reason, we call our CMS “green”. Moreover, our GCMS supports the creation of fully accessible web sites.

SMILINGPHOTOS - Bridging the Gap between Digital Photo Albums and Printed Photo Books

Topics: XML and Data Management; Personalized Web Sites and Services; Multimedia and User Interfaces; Protocols and Standards; Social Networks and Organizational Culture

Authors: Ombretta Gaggi and Fabrizio Ghidoni

Affiliation: University of Padua, Italy

Digital Object Identifier: 10.5220/0002808901130118

Proceedings of WEBIST 2010, ISBN: 978-989-674-025-2

Quick Abstract

The number of photos has significantly increased in the recent years together with the problem of how to manage them: a picture can be printed as is, arranged into a more interesting photo book or shared through the web. Digital photos have the advantage that can be easily stored and shared with family and friends from different cities or countries but we must consider that many people do not even see the PC screen as a convenient vehicle for synchronously reviewing and sharing of photos with others. This paper presents a framework to bridge the gap between digital web albums and printed photo books. The idea is to allow the user to create, at the same time, a photo book for later printing, and a multimedia presentation to share with friends not only the taken pictures but the experiences they told. The paper presents smilingPhotos a tool for this double authoring: the user creates a multimedia slideshow which can be enriched with audio (music or spoken) comments, transition effects, animations and definition of the layout of the images. The result can be shared across the network, or automatically translated into a static photo book suitable for printing.

MODELLING COGNITIVE TRANSACTIONS FOR ECONOMIC AND ACCOUNTING ANALYSIS

Topics: Intellectual Capital; K-Economy, K-Community and K-Enterprise

Author: Ettore Bolisani

Affiliation: University of Padua, Italy

Digital Object Identifier: 10.5220/0002332502420247

Proceedings of KMIS 2009/IC3K, ISBN: 978-989-674-013-9

Quick Abstract

When knowledge is treated as a fundamental factor of economic activity, the development of methods for assessing its economic value becomes essential. This issue has often been discussed both in the scientific literature and for the managerial practice, but with controversial results. This position paper argues that there is need to reflect on the foundational aspects of the problem, and suggests looking at the way the exchange of knowledge between traders underpins economic transactions and enables the production of economic value. A model of cognitive transaction, representing the way knowledge exchanges have an economic significance per se, is proposed as a starting point of future research on this issue. The critical and open questions of the application of this model, as well as the points of a research agenda, are illustrated.
