Abstract interpretation-based code certification for pervasive systems: Preliminary experiments

Proof carrying code is a general methodology for certifying that the execution of an untrusted mobile code is safe, according to a predefined safety policy. The basic idea is that the code supplier attaches a certifícate (or proof) to the mobile code which, then, the consumer checks in order to ensure that the code is indeed safe. The potential benefit is that the consumer's task is reduced from the level of proving to the level of checking, a much simpler task. Recently, the abstract interpretation techniques developed in logic programming have been proposed as a basis for proof carrying code [1]. To this end, the certifícate is generated from an abstract interpretation-based proof of safety. Intuitively, the verification condition is extracted from a set of assertions guaranteeing safety and the answer table generated during the analysis. Given this information, it is relatively simple and fast to verify that the code does meet this proof and so its execution is safe. This extended abstract reports on experiments which illustrate several issues involved in abstract interpretation-based code certification. First, we describe the implementation of our system in the context of CiaoPP: the preprocessor of the Ciao multi-paradigm (constraint) logic programming system. Then, by means of some experiments, we show how code certification is aided in the implementation of the framework. Finally, we discuss the application of our method within the área of pervasive systems which may lack the necessary computing resources to verify safety on their own. We herein illustrate the relevance of the information inferred by existing cost analysis to control resource usage in this context. Moreover, since the (rather complex) analysis phase is replaced by a simpler, efficient checking process at the code consumer side, we believe that our abstract interpretation-based approach to proof-carrying code becomes practically applicable to this kind of systems.

QR-VEY: Una piattaforma software per la creazione di sondaggi basata sulla tecnologia del QR-Code

Le metodologie per la raccolta delle idee e delle opinioni si sono evolute a pari passo con il progresso tecnologico: dalla semplice comunicazione orale si è passati alla diffusione cartacea, fino a che l'introduzione e l'evoluzione di internet non hanno portato alla digitalizzazione e informatizzazione del processo. Tale progresso ha reso possibile l'abbattimento di ogni barriera fisica: se in precedenza la diffusione di un sondaggio era limitata dall'effettiva possibilità di distribuzione del sondaggio stesso, lo sviluppo della rete globale ha esteso tale possibilità (virtualmente) a tutto il mondo. Nonostante sia un miglioramento non indifferente, è importante notare come la valorizzazione della diffusione di un sondaggio abbia inevitabilmente portato a trascurarne le proprietà e i vantaggi intrinsechi legati alla sua diffusione prettamente locale. Ad esempio, un sondaggio che mira a valutare la soddisfazione degli utenti riguardo alla recente introduzione di una nuova linea di laptop ottiene un guadagno enorme dall'informatizzazione, e dunque delocalizzazione, del processo di raccolta dati; dall'altro lato, un sondaggio che ha come scopo la valutazione dell'impatto sui cittadini di un recente rinnovamento degli impianti di illuminazione stradale ha un guadagno pressoché nullo. L'idea alla base di QR-VEY è la ricerca di un ponte tra le metodologie classiche e quelle moderne, in modo da poter sfruttare le proprietà di entrambe le soluzioni. Tale ponte è stato identificato nella tecnologia del QR-Code: è possibile utilizzare un generico supporto che presenti proprietà di localizzazione, come un foglio cartaceo, ma anche un proiettore di una conferenza, come base per la visualizzazione di tale codice, ed associare alla scansione dello stesso funzionalità automatizzate di raccolta di dati e opinioni.

Mystery at the library : encouraging library exploration using a pervasive mobile game

This paper presents Secret SLQ, a pervasive mobile game that aims to encourage eight to fourteen year olds to engage with the State Library of Queensland. The game sets out to encourage people to visit and explore the library, as well as educate a generation of young people and parents who may visit the library but have no idea of the treasures that it holds. The research explores how smartphone technology can be used to deliver an engaging and educational experience. The game aims to provide a fun and interactive way to guide participants through a multi-leveled library building, to search for unique QR codes to unlock clues, answer quiz questions and progress further up a leaderboard. This paper outlines the design and initial deployment of the game, reporting on results from a usability study and discussing initial observations made by librarians. Findings indicate that the mobile platform is suitable for delivering such experiences but consideration is needed when embedding games in such large environments so as not to confuse players as they play.

Gamification: applicazioni sociali e mobili

L'obiettivo di questa tesi, in base all'analisi di atti di convegni e workshop, lettura di libri e articoli pubblicati in siti Web, in materie di gamification, è per prima cosa, spiegare il concetto della gamification, partendo da alcune definizioni date da ricercatori e progettisti di videogiochi, cercando di capire sia i fattori positivi, sia i fattori negativi. Si vogliono elencare e spiegare gli elementi di gioco che compongono la gamification, con particolare attenzione alle meccaniche, come punti, distintivi, premi e dinamiche, come competenza, espressione di sè, status sociale, elementi collegati tra di loro, analizzando quali meccaniche originano certe dinamiche. Si cercherà anche di analizzare la gamification sotto gli aspetti psicologici e di User Experience che innescano le motivazioni intrinseche ed estrinseche delle persone, le prime azionate dalle meccaniche, le seconde azionate dalle dinamiche della gamification e l'importanza di ciò nella progettazione di applicazioni gamificate. Si vogliono esaminare ed illustrare in generale, progetti i quali adottano tecniche di gamification, che spaziano dal fitness fino ad attività di marketing per capire i benefici riscontrati. Si vuole inoltre scoprire se ci sono dei validi presupposti per sviluppare App gamificate per smarphone, che sfruttino alcune specifiche tecniche dei dispositivi mobili come, connettività, il GPS ed i sensori come ad esempio, l'accelerometro ed altre tecnologie come il lettore NFC, QR-code. Infine, come caso di studio, saranno testate tre app per smarphone, Foursquare, tramite la quale un utente può consultare e lasciare consigli sui luoghi nelle sue vicinanze, Swarm, tramite la quale un utente oltre ad effettuare il check-in in un luogo, può vedere se ci sono amici nelle vicinanze e Waze, tramite la quale un utente può inviare ed apprendere informazioni relative al traffico.

Orientation passport : using gamification to engage university students

Adding game elements to an application to motivate use and enhance the user experience is a growing trend known as gamification. This study explores the use of game achievements when applied to a mobile application designed to help new students at university. This paper describes the foundations of a design framework used to integrate game elements to Orientation Passport, a personalised orientation event application for smart phones. Orientation Passport utilises game achievements to present orientation information in an engaging way and to encourage use of the application. The system is explained in terms of the design framework, and the findings of a pilot study involving 26 new students are presented. This study contributes the foundations of a design framework for general gamified achievement design. It also suggests that added game elements can be enjoyable but can potentially encourage undesirable use by some, and aren't as enjoyable if not enforced properly by the technology. Consideration is also needed when enforcing stricter game rules as usability can be affected.

Using QR codes to aid accessibility in a museum

Purpose – This paper describes visitors' reactions to using an Apple iPad or smartphone to follow trails in a museum by scanning QR codes and draws conclusions on the potential for this technology to help improve accessibility at low-cost. Design/methodology/approach – Activities were devised which involved visitors following trails around museum objects, each labelled with a QR code and symbolised text. Visitors scanned the QR codes using a mobile device which then showed more information about an object. Project-team members acted as participant-observers, engaging with visitors and noting how they used the system. Experiences from each activity fed into the design of the next. Findings – Some physical and technical problems with using QR codes can be overcome with the introduction of simple aids, particularly using movable object labels. A layered approach to information access is possible with the first layer comprising a label, the second a mobile-web enabled screen and the third choices of text, pictures, video and audio. Video was especially appealing to young people. The ability to repeatedly watch video or listen to audio seemed to be appreciated by visitors with learning disabilities. This approach can have low equipment-cost. However, maintaining the information behind labels and keeping-up with technological changes are on-going processes. Originality/value – Using QR codes on movable, symbolised object labels as part of a layered information system might help modestly-funded museums enhance their accessibility, particularly as visitors increasingly arrive with their own smartphones or tablets.

Effective measures to decrease air contaminants through risk and control visualization : a study of the effective use of QR codes to facilitate safety training

Woodworking industries still consists of wood dust problems. Young workers are especially vulnerable to safety risks. To reduce risks, it is important to change attitudes and increase knowledge about safety. Safety training have shown to establish positive attitudes towards safety among employees. The aim of current study is to analyze the effect of QR codes that link to Picture Mix EXposure (PIMEX) videos by analyzing attitudes to this safety training method and safety in student responses. Safety training videos were used in upper secondary school handicraft programs to demonstrate wood dust risks and methods to decrease exposure to wood dust. A preliminary study was conducted to investigate improvement of safety training in two schools in preparation for the main study that investigated a safety training method in three schools. In the preliminary study the PIMEX method was first used in which students were filmed while wood dust exposure was measured and subsequently displayed on a computer screen in real time. Before and after the filming, teachers, students, and researchers together analyzed wood dust risks and effective measures to reduce exposure to them. For the main study, QR codes linked to PIMEX videos were attached at wood processing machines. Subsequent interviews showed that this safety training method enables students in an early stage of their life to learn about risks and safety measures to control wood dust exposure. The new combination of methods can create awareness, change attitudes and motivation among students to work more frequently to reduce wood dust. 

New QR Survey Methodologies to Analyze User Perception of Service Quality in Public Transport: The Experience of Madrid

Customer Satisfaction Surveys (CSS) have become an important tool for public transport planners, as improvements in the perceived quality of service lead to greater use of public transport and lower traffic pollution. Until now, Intelligent Transportation System (ITS) enhancements in public transport have traditionally included fleet management systems based on Automatic Vehicle Location (AVL) technologies, which can be used to optimize routing and scheduling, and to feed real-time information into passenger information channels. However, surveys of public transport users could also benefit from the new information technologies. As most customers carry their smartphones when traveling, Quick Response (QR) codes open up the possibility of conducting these surveys at a lower cost.This paper contributes to the limited existing literature by developing the analysis of QR codes applied to CSS in public transport and highlighting their importance in reducing the cost of data collection and processing. The added value of this research is that it provides the first assessment of a real case study in Madrid (Spain) using QR codes for this purpose. This pilot experience was part of a research project analyzing bus service quality in the same case study, so the QR code survey (155 valid questionnaires) was validated using a conventional face-to-face survey (520 valid questionnaires). The results show clearly that, after overcoming a few teething troubles, this QR code application will ultimately provide transport management with a useful tool to reduce survey costs

Extending the GUIDE@HAND Tourist Guide Application with QR Codes for Museum Learning

The following paper attempts to encompass the opportunities for applying QR codes for museums and exhibits through the example of the Hungarian Museum of Environmental Protection and Water Management (Esztergom, Hungary). Besides providing interactivity in the museum for the mobile phone generation through the utilization of a device and a method that they are familiar with, it is important to explain how and why it is worthwhile to “adorn” the exhibits with these codes. In this paper we also touch upon the technical issues of how an existing mobile phone application can be incorporated into and used for the presentation of the museum.
