Investigating retrospective interoperability between the accessible and mobile webs with regard to user input

Chen, Tianyi January 2011 (has links)
The World Wide Web (Web) has become a key technology to provide access to on-line information. The Mobile Web users, who access the Web using small devices such as mobile phones and Personal Digital Assistants (PDAs), make errors on entering text and controlling cursors. These errors are caused by both the characteristics of a device and the environment in which it is used, and are called situational impairments. Disabled Web users, on the other hand, have difficulties in accessing the Web due to their impairments in visual, hearing or motor abilities. We assert that errors experienced by the Mobile Web users share similarity in scope with those hindering motor-impaired Web users with dexterity issues, and existing solutions from the motor-impaired users domain can be migrated to the Mobile Web domain to address the common errors.Results of a systematic literature survey have revealed 12 error types that affect both the Mobile Web users and disabled Web users. These errors range from unable to locate a key to unable to pin-point a cursor. User experiments have confirmed that the Mobile Web users and motor-impaired Web users share errors in scope: they both miss key presses, press additional keys, unintentionally press a key more than once or press a key too long. In addition, both small device users and motor-impaired desktop users have difficulties in performing clicking, multiple clicking and drag selecting. Furthermore, when small device users are moving, both the scope and the magnitude of the errors are shared. In order to address these errors, we have migrated existing solutions from the disabled Web users domain into the Mobile Web users domain. We have developed a typing error correction system for the Mobile Web users. Results of the user evaluation have indicated that the proposed system can significantly reduce the error rates of the Mobile Web users.This work has an important contribution to both the Web accessibility field and the Mobile Web field. By leveraging research from the Web accessibility field into the Mobile Web field, we have linked two disjoint domains together. We have migrated solutions from one domain to another, and thus have improved the usability and accessibility of the Mobile Web.

Database metadata requirements for automated web development : a case study using PHP

Mgheder, Mohamed Ahmed January 2009 (has links)
The Web has come a long way. It started as a distributed document repository and quickly became the spring board for a new type of application. Propped on top of the original HTML+HTTP architecture, this new application platform shifted the way the architecture was used so that commands and functionality were embedded in the form data of Web requests rather than in the HTTP command conveying the request. This approach enabled Web requests to convey any type of data, not just document operations. This is occurring because the Web provides such a powerful platform on which to create applications. This is occurring because web development methods are still evolving toward the structure and stability required taking on this enormous new role. As the needs of developers change, certain themes that arise more frequently than others become embedded into new environments to support those needs. Until recently, Web application programming has largely been done with a set of keywords and metaphors developed long before the Web became a popular place to program. APIs have been developed to support Web specific features, but they are no replacement for fundamental changes in the programming environment itself. The growth of Web applications requires a new type of programming designed specifically for the needs of the Web. This thesis aims to contribute towards the development of an abstract framework to generate abstract and dynamic Web user interfaces that are not developed to a specific platform. To meet this aim, this thesis suggests a general implementation of a prototype system that uses the information in database metadata in conjunction with PHP. Database metadata is richer in providing the information needed to build dynamic user interfaces. This thesis uses PHP and the abstract library ADOdb to provide us with a generalised database metadata based prototype. PHP does not have any restrictions on accessing and extracting database metadata from numerous database management systems. As a result, PHP and relational database were used to build the proposed framework. Additionally, ADOdb was used to link the two mentioned technologies. The implemented framework in this thesis demonstrates that it is possible to generate different automatic Web entry forms that are not specific at any platform.

Remote control service system architecture and dynamic web user interface generation

Guo, Xi January 2011 (has links)
According to current development of internet technology, remote control over the internet becomes a heated discussed topic. Some recent technologies such as Service-Oriented Architecture (SOA), web service and ontology offer great opportunity for remote control over the internet and a lot of research has been done into this topic. However, there are still many challenges in architecture design and dynamic user interface generation. Architectures in this research field lack clear description of controlled machine model as well as related knowledge support. Also, there is little system support further control service development. There is little research on web user interface design for remote control system over the internet. The design of web user interface has the challenge of overcoming the limitations of web technology to satisfactorily support different machines, users and control process requirements. This work overcomes the limitations on architecture by offering a SOA based design which allows both multiple users and distributed machine access. The system applies a machine model for the description of the machine structure and functions, which help the system to reason about machine components and their relationships with instructions. With a web service based design, different machines can be connected via the system and execute user commands. Using semantic description and ontology based methods the system can automatically retrieve machine information and generate the structure and function descriptions for different machines. Moreover, the system provides services which can support further development in remote control services. The proposed architecture improves on former designs, and offers a flexible architecture for remote control services over the internet. An intelligent web user interface is also introduced in this work. The design separates the interface data structure from the data representation. Supported by the remote control service development environment, the user interface could adapt to the control sessions. Semantic descriptions are used to describe the page data structure, session context as well as control command. Therefore, control page content can be adapted by the computer to real time control session. At the same time, a session dependent navigation is designed to resolve the problem of changeable requirements for multiple-machine web user interface. With a message driven model and a session dependent semantic data structure, the required machine data can be analysed by the system and categorised according to user s requirements. Compare with other designs, this service offers a method for web user interface generation for different machines, users and can adapt to different control processes. The design is demonstrated in five evaluation scenarios aimed at testing different aspects of the system. Evaluation demonstrates the design proposed in this thesis is feasible. It also shows the design can be applied to different areas and adapted to different control related requirements well.

Analýza uživatelského chování vzhledem k ukládání digitální stopy bez vědomí uživatele / Analysis of user behavior due to the storing of digital footprints without knowledge of the user

Pappová, Michaela January 2017 (has links)
Digital footprint designates data left behind a user movement in the digital environment or with the interaction with it. We distinguish active and passive digital footprint, together creating the digital identity of a user. The biggest benefit of the digital footprint for a user is the personalization of internet content. It also creates the reputation of a user on the internet. Other parties can utilize a digital footprint for purposes of marketing, science, HR research, and criminology. Digitial footprint can be actively affected and limited by users and different strategies for managing it exists. The aim of this thesis is to analyze user behavior of students in digital environment and their knowledge of digital footprint. It's focused on the relation between users knowledge about digital footprint existence and his real behavior. To fulfill the main purpose of the thesis researched questions are stated and the strategies of user behavior and managing their data are investigated afterwards. The knowledge of students and their real behavior with an accent on their motivation and reasons are determined in semi structured interviews. The relation between knowledge and real behavior has been found, as well as a strong influence of this relation on a user behavior strategy online.

Fashion E-Commerce in the 3D Digital Era : A 3D Interactive Web User Interface for Online Products / Fashion E-Commerce i 3D Digital Eramode : Ett 3D-interaktivt webbgränssnitt för online-produkter

Zhou, Hanyue January 2018 (has links)
Fashion brands have always been avant-garde in embracing new technologies and new formats of retail business models. The rapid development in 3D digital technologies, including 3D scanning, 3D modelling and 3D web rendering, have brought many new opportunities to the fashion industry, especially in shaping the future fashion e-commerce. The traditional 2D user interface and 2D media content have limited ability of displaying every detail of a product in full 360 degree, and the color accuracy of products in pictures is also a common problem. This thesis focuses on how to use 3D technologies to enhance the brand identity and  to reduce return rate, by designing and implementing a web 3D user interface for fashion e-commerce. An interactive 3D product user interface were designed and used for test. The results presented the pros and cons of the designed 3D user interface, and evaluated to what extent can this approach help to solve the brand identity problem and the high return rate issue for fashion e-commerce. It turns out that indeed the 3D user interface is rich in detail storytelling and the product accuracy can be improved by using the Physically Based Rendering technology and dynamic virtual lighting environments. However, the results also indicate that there are still lots of technical constraints for developing the virtual showrooms and the 3D user interface. / Fashion varumärken har alltid varit avantgarde i att omfamna ny teknik och nya format av detaljhandel affärsmodeller. Den snabba utvecklingen inom 3D-digitalteknik, inklusive 3D-skanning, 3D-modellering och 3D-webbearbetning, har medfört många nya möjligheter till modebranschen, särskilt när det gäller att forma framtida fashion e-handel. Det traditionella 2D-användargränssnittet och 2D-medieinnehållet har begränsad förmåga att visa alla detaljer i en produkt i full 360 grader, och färgnoggrannheten hos produkter i bilder är också ett vanligt problem. Denna avhandling fokuserar på hur man använder 3D-teknik för att förbättra varumärkets identitet och minska avkastningsgraden genom att utforma och implementera ett webb 3D-användargränssnitt för mode-e-handel. Ett interaktivt 3D-produkt användargränssnitt designades och användes för test. Resultaten presenterade fördelar och nackdelar med det utformade 3D-användargränssnittet och utvärderades i vilken utsträckning kan detta tillvägagångssätt hjälpa till att lösa varumärkesidentitetsproblemet och problemet med hög avkastning för fashion e-handel. Det visar sig att 3D-användargränssnittet är rikt på detaljerad berättande och produktnoggrannheten kan förbättras med hjälp av fysisk baserad renderingsteknik och dynamiska virtuella ljusmiljöer. Resultaten visar emellertid också att det fortfarande finns många tekniska begränsningar för att utveckla virtuella showroom och 3D-användargränssnittet.

The development of a single nucleotide polymorphism database for forensic identification of specified physical traits

Alecia Geraldine Naidu January 2009 (has links)
<p>Many Single Nucleotide Polymorphisms (SNPs) found in coding or regulatory regions within the human genome lead to phenotypic differences that make prediction of physical appearance, based on genetic analysis, potentially useful in forensic investigations. Complex traits such as pigmentation can be predicted from the genome sequence, provided that genes with strong effects on the trait exist and are known. Phenotypic traits may also be associated with variations in gene expression due to the presence of SNPs in promoter regions. In this project, the identification of genes associated with these physical traits of potential forensic relevance have been collated from the literature using a text mining platform and hand curation. The SNPs associated with these genes have been acquired from public SNP repositories such as the International HapMap project, dbSNP and Ensembl. Characterization of different population groups based on the SNPs has been performed and the results and data stored in a MySQL database. This database contains SNP genotyping data with respect to physical phenotypic differences of forensic interest. The potential forensicrelevance of the SNP information contained in this database has been verified through in silico SNP analysis aimed at establishing possible relationships between SNP occurrence and phenotype. The software used for this analysis is MATCH&trade / .</p>
