Design, development and evaluation of a portable recording system to capture dynamic presentations using the teacher's tablet PC

Computers and multimedia equipment have improved a lot in the last years. They have reduced their cost and size while at the same time increased their capabilities. These improvements allowed us to design and implement a portable recording system that also integrates the teacher´s tablet PC to capture what he/she writes on the slides and all that happens in it. This paper explains this system in detail and the validation of the recordings that we did after using it to record all the lectures the “Communications Software” course in our university. The results show that pupils used the recordings for different purposes and consider them useful for a variety of things, especially after missing a lecture.

Touch ‘n’ sketch: pen and fingers on a multi-touch sketch application for tablet PC’s

In many creative and technical areas, professionals make use of paper sketches for developing and expressing concepts and models. Paper offers an almost constraint free environment where they have as much freedom to express themselves as they need. However, paper does have some disadvantages, such as size and not being able to manipulate the content (other than remove it or scratch it), which can be overcome by creating systems that can offer the same freedom people have from paper but none of the disadvantages and limitations. Only in recent years has the technology become massively available that allows doing precisely that, with the development in touch‐sensitive screens that also have the ability to interact with a stylus. In this project a prototype was created with the objective of finding a set of the most useful and usable interactions, which are composed of combinations of multi‐touch and pen. The project selected Computer Aided Software Engineering (CASE) tools as its application domain, because it addresses a solid and well‐defined discipline with still sufficient room for new developments. This was the result from the area research conducted to find an application domain, which involved analyzing sketching tools from several possible areas and domains. User studies were conducted using Model Driven Inquiry (MDI) to have a better understanding of the human sketch creation activities and concepts devised. Then the prototype was implemented, through which it was possible to execute user evaluations of the interaction concepts created. Results validated most interactions, in the face of limited testing only being possible at the time. Users had more problems using the pen, however handwriting and ink recognition were very effective, and users quickly learned the manipulations and gestures from the Natural User Interface (NUI).

Use of Tablet Pcs in Higher Education: A new Strategy for Training Engineers in European Bachelors and Masters Programmes

The use of technology in classrooms in Spanish universities has been following an upward path, and in many cases technological devices are substituting other materials that until now have been used, such as books, notebooks and so on. Step by step in higher education, more of these latest generationdevices are being used, and are providing significant improvements in training. Nowadays, there are Spanish universities that use tablets, a device with multiple applications for teaching as well as for students to study differently. They are definitely a notable innovation that will gradually become incorporated into university life. Tablet PCs make teaching more dynamic and available to students through the use of up to date digital materials, something which is key in training engineers. This paper presents their different functions employed in three Spanish universities to support teachingin engineering degrees and masters using the tablet PC, and their impact on the training process. Possible uses in specific programs like the Erasmus Masters Programmes are also assessed. The main objective of using tabletsis to improve the academic performance of students through the use of technology.

What will the Apple iPad deliver for newspapers?

The launch of the Apple iPad in January 2010 was one of the most anticipated and publicised launched of a new technological device in recent history. Positioning itself as between a smart phone and a PC, but with the attributes of both, Apple have sought to develop a new market niche with the iPad for tablet PC devices, and early signs are that market expectations are being met.. The iPad’s launch was potentially fortuitous for the newspaper industry worldwide, as it offered the potential to address its two recurring problems: the slow but inexorable decline of print media circulation, and the inability to satisfactorily monetise online readerships. As a result, the Apple iPad has benefited from an enormous amount of free publicity in newspapers, as they develop their own applications (apps) for the device. This paper reports on findings from work undertaken through Smart Services CRC into potential take-up and likely uses of the iPad, and their implications for the news media industry. It reports on focus group analysis undertaken in the mid-2010 using “customer job mapping” methodologies, that draw attention to current gaps in user behaviour in terms of available devices, in order to anticipate possibilities beyond the current “three screens” of PC, mobile phone and television.

Review of Apple iPad news applications : new media service

The launch of the Apple iPad on January 2010 has seen considerable interest from the newspaper and publishing industry in developing content and business models for the tablet PC device that can address the limits of both the print and online news and information media products. It is early days in the iPad’s evolution, and we wait to see what competitor devices will emerge in the near future. It is apparent, however, that it has become a significant “niche” product, with considerable potential for mass market expansion over the next few years, possibly at the expense of netbook sales. The scope for the iPad and tablet PCs to become a “fourth screen” for users, alongside the TV, PC and mobile phone, is in early stages of evolution. The study used five criteria to assess iPad apps: • Content: timeliness; archive; personalisation; content depth; advertisements; the use of multimedia; and the extent to which the content was in sync with the provider brand. • Useability: degree of static content; ability to control multimedia; file size; page clutter; resolution; signposts; and customisation. • Interactivity: hyperlinks; ability to contribute content or provide feedback to news items; depth of multimedia; search function; ability to use plug-ins and linking; ability to highlight, rate and/or save items; functions that may facilitate a community of users. • Transactions capabilities: ecommerce functionality; purchase and download process; user privacy and transaction security. • Openness: degree of linking to outside sources; reader contribution processes; anonymity measures; and application code ownership.

Unrestricted Kannada online handwritten akshara recognition using SDTW

In this paper, we present an unrestricted Kannada online handwritten character recognizer which is viable for real time applications. It handles Kannada and Indo-Arabic numerals, punctuation marks and special symbols like $, &, # etc, apart from all the aksharas of the Kannada script. The dataset used has handwriting of 69 people from four different locations, making the recognition writer independent. It was found that for the DTW classifier, using smoothed first derivatives as features, enhanced the performance to 89% as compared to preprocessed co-ordinates which gave 85%, but was too inefficient in terms of time. To overcome this, we used Statistical Dynamic Time Warping (SDTW) and achieved 46 times faster classification with comparable accuracy i.e. 88%, making it fast enough for practical applications. The accuracies reported are raw symbol recognition results from the classifier. Thus, there is good scope of improvement in actual applications. Where domain constraints such as fixed vocabulary, language models and post processing can be employed. A working demo is also available on tablet PC for recognition of Kannada words.

Recognition of open vocabulary, online handwritten pages in Tamil script

In this work, we describe a system, which recognises open vocabulary, isolated, online handwritten Tamil words and extend it to recognize a paragraph of writing. We explain in detail each step involved in the process: segmentation, preprocessing, feature extraction, classification and bigram-based post-processing. On our database of 45,000 handwritten words obtained through tablet PC, we have obtained symbol level accuracy of 78.5% and 85.3% without and with the usage of post-processing using symbol level language models, respectively. Word level accuracies for the same are 40.1% and 59.6%. A line and word level segmentation strategy is proposed, which gives promising results of 100% line segmentation and 98.1% word segmentation accuracies on our initial trials of 40 handwritten paragraphs. The two modules have been combined to obtain a full-fledged page recognition system for online handwritten Tamil data. To the knowledge of the authors, this is the first ever attempt on recognition of open vocabulary, online handwritten paragraphs in any Indian language.

Analyse des pratiques de lecture sur livres électroniques chez les étudiants universitaires

La lecture numérique prend de plus en plus de place dans l'espace global de la lecture des étudiants. Bien que les premiers systèmes de lecture numérique, communément appelés livres électroniques, datent déjà de plusieurs années, les opinions quant à leur potentiel divergent encore. Une variété de contenus universitaires numériques s’offre aujourd’hui aux étudiants, entraînant par le fait même une multiplication d'usages ainsi qu'une variété de modes de lecture. Les systèmes de lecture numérique font maintenant partie intégrante de l’environnement électronique auquel les étudiants ont accès et méritent d’être étudiés plus en profondeur. Maintes expérimentations ont été menées dans des bibliothèques publiques et dans des bibliothèques universitaires sur les livres électroniques. Des recherches ont été conduites sur leur utilisabilité et sur le degré de satisfaction des lecteurs dans le but d’en améliorer le design. Cependant, très peu d’études ont porté sur les pratiques de lecture proprement dites des universitaires (notamment les étudiants) et sur leurs perceptions de ces nouveaux systèmes de lecture. Notre recherche s’intéresse à ces aspects en étudiant deux systèmes de lecture numérique, une Tablet PC (dispositif nomade) et un système de livres-Web, NetLibrary (interface de lecture intégrée à un navigateur Web). Notre recherche étudie les pratiques de lecture des étudiants sur ces systèmes de lecture numérique. Elle est guidée par trois questions de recherche qui s’articulent autour (1) des stratégies de lecture employées par des étudiants (avant, pendant et après la lecture), (2) des éléments du système de lecture qui influencent (positivement ou négativement) le processus de lecture et (3) des perceptions des étudiants vis-à-vis la technologie du livre électronique et son apport à leur travail universitaire. Pour mener cette recherche, une approche méthodologique mixte a été retenue, utilisant trois modes de collecte de données : un questionnaire, des entrevues semi-structurées avec les étudiants ayant utilisé l’un ou l’autre des systèmes étudiés, et le prélèvement des traces de lecture laissées par les étudiants dans les systèmes, après usage. Les répondants (n=46) étaient des étudiants de l’Université de Montréal, provenant de trois départements (Bibliothéconomie & sciences de l’information, Communication et Linguistique & traduction). Près de la moitié d’entre eux (n=21) ont été interviewés. Parallèlement, les traces de lecture laissées dans les systèmes de lecture par les étudiants (annotations, surlignages, etc.) ont été prélevées et analysées. Les données des entrevues et des réponses aux questions ouvertes du questionnaire ont fait l'objet d'une analyse de contenu et un traitement statistique a été réservé aux données des questions fermées du questionnaire et des traces de lecture. Les résultats obtenus montrent que, d’une façon générale, l’objectif de lecture, la nouveauté du contenu, les habitudes de lecture de l’étudiant de même que les possibilités du système de lecture sont les éléments qui orientent le choix et l’application des stratégies de lecture. Des aides et des obstacles à la lecture ont été identifiés pour chacun des systèmes de lecture étudiés. Les aides consistent en la présence de certains éléments de la métaphore du livre papier dans le système de lecture numérique (notion de page délimitée, pagination, etc.), le dictionnaire intégré au système, et le fait que les systèmes de lecture étudiés facilitent la lecture en diagonale. Pour les obstacles, l’instrumentation de la lecture a rendu l’appropriation du texte par le lecteur difficile. De plus, la lecture numérique (donc « sur écran ») a entraîné un manque de concentration et une fatigue visuelle notamment avec NetLibrary. La Tablet PC, tout comme NetLibrary, a été perçue comme facile à utiliser mais pas toujours confortable, l’inconfort étant davantage manifeste dans NetLibrary. Les étudiants considèrent les deux systèmes de lecture comme des outils pratiques pour le travail universitaire, mais pour des raisons différentes, spécifiques à chaque système. L’évaluation globale de l’expérience de lecture numérique des répondants s’est avérée, dans l’ensemble, positive pour la Tablet PC et plutôt mitigée pour NetLibrary. Cette recherche contribue à enrichir les connaissances sur (1) la lecture numérique, notamment celle du lectorat universitaire étudiant, et (2) l’impact d’un système de lecture sur l’efficacité de la lecture, sur les lecteurs, sur l’atteinte de l’objectif de lecture, et sur les stratégies de lecture utilisées. Outre les limites de l’étude, des pistes pour des recherches futures sont présentées.
