  • IoT is attracting attention as the development of the Internet and the spread of smart devices are rapidly increasing worldwide. As IoT is integrated into everyday life, the market is getting bigger. So, experts predict that IoT devices will grow to more than one trillion in a decade. Techniques related to IoT are also being developed steadily, and studies are underway to develop IoT in various fields. However, vendors launching IoT services do not interact with data from other platforms. Therefore, it is limited to growing into a big market by facing the obstacle called the silo phenomenon. To solve this problem, web technology attracts attention. Web technology can interact with data regardless of platform, and it can not only develop various services using the data, but also reduce unnecessary costs for developers. In this paper, we have studied a web - based open IoT system that can transmit data independently in real time to the IoT platform.

  • It is required to enhance the value of ISBN as a tool for book search, identification, browsing, and improve the accessability and search capability of library OPAC. Bookmarklet is a small size javascript which can be saved as URL in a web browser bookmark or web page hyperlink. Open source bookmarklet can extract ISBN from web pages and search a book from library OPAC using the ISBN, so it is recognized as a simple but powerful search tool. In foreign countries, commercial library system vendors, libraries, OCLC, etc. are providing bookmarklets which allow a user to search for library holdings and loan information in a real time while he/she is travelling in an online bookshop web page. Therefore, this paper compared and analyzed international bookmarklets application examples and proposed LibraryLookup service in which library OPAC and online bookshop can make use of the bookmarklets.

  • In this paper, we propose the method of converting 2D image to 3D image using linear curves in HTML5. We use only one image without any other information about depth map for creating 3D images. So we filter the original image to extract RGB colors for left and right eyes. After selecting the ready-made control point of linear curves to set up depth values, users can set up the depth values and modify them. Based on the depth values that the end users select, we reflect them. Anaglyph 3D is automatically made with the whole and partial depth information. As all of this work has been designed and implemented in Web environment using HTML5, it is very easy and convenient and end users can create any 3D image that they want to make.

  • In this paper, we propose a method to convert 2D image to 3D anaglyph using quadratic & cubic B$\acute{e}$zier Curves in HTML5. In order to convert 2D image to 3D anaglyph image, we filter the original image to extract the RGB color values and create two images for the left and right eyes. Users are to set up the depth values of the image through the control point using the quadratic and cubic B$\acute{e}$zier curves. We have processed the depth values of 2D image based on this control point to create the 3D image conversion reflecting the value of the control point which the users select. All of this work has been designed and implemented in Web environment in HTML5. So we have made it for anyone who wants to create their 3D images and it is very easy and convenient to use.

  • Recently, as user feedback such as social reading become active, demand has been increased on e-book contents making which is based on user feedback. However, to reflect the user feedback onto the e-book, direct coding is required, which was difficult to the author who was not good at programming. To resolve this problem, Block assembly style feedback editor system, using Blockly was developed. This editor enables to reflect the user feedback by area allocation, component allocation, block editing, and code generating insertion, contrary to the existing way of programming realization in which direct coding was required for input, processing and output separately. This system was developed by using HTML. Javascript, PHP, and Codeigniter. Block editing is enabled to do provision and assembly of blocks by Blockly. The function of code generation & insertion allows to insert the Library function code. Through this system, the general users who are not capable of coding also can reflect feedback without doing actual coding.

  • Recently, HTML5 have drawn many people's attention since it is considered as a next-generation web standard and can implement a lot of graphic and multimedia-related techniques on a web browser without installing programs separately. In this paper, we implement a game independent of platforms, such as iOS and Android, using the HTML5 canvas. In the game, the main character can move up, down, left, and right not to collide with neighboring enemies. If the character collides with an enemy, the HP (hit point) gauge bar reduces. On the other hand, if the character obtains heart items, the gauge bar increases. In the future, we will add various items to the game and will diversify its user interfaces by applying computer vision techniques such as various gesture recognition.

  • As web-based programming tools(such as flash action script, javascript, java and etc.) has been improved and it has become more aware to take interactivity importantly as users' whole experience, web sites have evolved from the form of webzine to the form of interactive application that displays more interactive interface and gives instant feedbacks for the users' inputs. Web, rather than software, is used to execute relatively easy tasks by users of various levels, so that web sites could give more fun and less cognitive burden by supporting users' tasks in more interactive way. This paper examined design strategies to make more interactive web by figuring out definition of web interaction as users' experience and by analyzing web interaction design trends from cases of interactive web sites. The ultimate objective of this paper is show how design strategies can be adapted in the web interaction design process. Thus, case study of designing interactive bookshell in E-book site was done and is demonstrating one way of adapting strategies to design web interaction.
