The web has become indispensable in all of our daily lives. We communicate, study and get information with others through the web. This behavior also continues in the smart phone environment. The biggest problem is that the small display screen of a smart phone degrades the accuracy in selecting or manipulating content for people with low vision. To compensate for this, voice guidance services that combine touch and voice, such as VoiceOver and Talkback, are currently provided to smart phone devices. However, restrictions arise in GUI, TTS control problems, and content expansion and selection. In addition, unnecessary content is also output by voice, which causes fatigue for low vision people to use. In this study, we propose a mobile web browser interface that selects and enlarges a desired area from web browsers and contents, or outputs it as a voice so that people with low vision can easily use the mobile web browser. In this paper, we propose a context selective focusing function that enables selection for each element of web content. In addition, we intend to develop a mobile voice web browser that can enlarge the selected content or output it by voice.

An app that users can conveniently use has been an explosive increase in the emergence of smart devices, including smart phones. However, the advent of various smart appliances operating systems, acting as an inhibitory factor to the development of the application. Accordingly, there has been a growing interest in HTML5 that can simultaneously support various platforms. HTML5 using the browser is used in the most innovative way of cross-platform. However, it does not show the complete compatibility for now. Depending on the browser of the environment, the difference between the initial load time of Web pages out. Therefore, to understand the cause of slowing down the browser-specific initial load time through the analysis of HTML5, JavaScript and CSS. Look for ways that can further improve the initial load rate.

A user can use resources on the Semantic Web using a Semantic Web browser. In order to utilize the functions of Semantic Web browsers in education, we compared the functions of well-known Semantic Web browsers such as Tabulator, Contextual Search Browser (CSB), Magpie, and Piggy Bank. In order to utilize Semantic Web browsers in education, a user needs to understand the features of each Semantic Web browser and our work can help both teachers and students. Tabulator is an RDF browser that can help to check whether resources can be used for learning and relevance of resources. CSB can be used to search educational resources using a conrtext file that contains the subjects of learning. It can also help learning by showing semantic web resources in the form of triple set as well as by supporting highlighting function. Magpie can help learners without basic knowledge on learning materials by providing interpretation based on a glossary file and related background knowledge. Piggy Bank supports conversion of web resources into semantic web resources and allows to browse semantic web resources in various views as well as to share semantic web resources.

Compared to the existing PC which uses a mouse and a keyboard, the touchscreen-based portable PC allows the user to use fingers, requiring new operation methods. However, current touchscreen-based web browser operations in many cases involve merely having fingers move simply like a mouse and click, or not corresponding well to the user's sensitivity and the structure of one's index finger, making itself difficult to be used during walking. Therefore, the goal of this study is to develop finger gestures which facilitate the interaction between the interface and the user, and make the operation easier. First, based on the frequency of usage in the web browser and preference, top eight functions were extracted. Then, the users' structural knowledge was visualized through sketch maps, and the finger gestures which were applicable in touchscreens were derived through the Meaning in Mediated Action method. For the front/back page, and up/down scroll functions, directional gestures were derived, and for the window closure, refresh, home and print functions, letter-type and icon-type gestures were drawn. A validation experiment was performed to compare the performance between existing operation methods and the proposed one in terms of execution time, error rate, and preference, and as a result, directional gestures and letter-type gestures showed better performance than the existing methods. These results suggest that not only during the operation of touchscreen-based web browser in portable PC but also during the operation of telematics-related functions in automobile, PDA and so on, the new gestures can be used to make operation easier and faster.

As the software industry has developed, the attacks making use of software vulnerability has become a big issue in society. In particular, because the attacks using the vulnerability of web browsers bypass Windows protection mechanism, web browsers can readily be attacked. To protect web browsers against security threat, research on fuzzing has constantly been conducted. However, most existing web browser fuzzing tools use a simple fuzzing technique which randomly mutates DOM tree. Therefore, this paper analyzed existing web browser fuzzing tools and the patterns of their already-known vulnerability to propose an event and command based fuzzing tool which can detect the latest web browser vulnerability more effectively. Three kinds of existing fuzzing tools were compared with the proposed tool. As a result, it was found that the event and command based fuzzing tool proposed was more effective.
