Since affective computing has been introduced in 90s, affect recognition technology has achieved substantial progress recently. However, the application of user emotion recognition into software user interface is in its early stages. In this paper, we describe a new approach for developing mobile user interface which could react differently depending on user emotion states. First, an emotion reaction model is presented which determines user interface reactions for each emotional state. We introduce a pair of mappings from user states to different user interface versions. The reacting versions are implemented by a set of variations for a view. Further, we present an authoring framework to help developers/designers to create emotion-aware reactions based on the proposed emotion reaction model. The authoring framework is necessary to alleviate the burden of creating and handling multi versions for views at the development process. A prototype implementation is presented as an extension of the existing authoring tool DAT4UX. Moreover, a proof-of-concept application featuring an emotion-aware interface is developed using the tool.

The work of creating character motion needs the higher professional technology and sense and the creating work of realistic and natural motion possess the most part of production term. In this paper we introduce the easy and convenient 3D animation authoring tool which makes the motion based on whole-body inverse kinematics and motion editing function. The proposed 3D animation authoring tool uses the forward kinematics using quaternion and whole-body inverse kinematics to determine the rotation and displacement of skeleton. Also, it provides the motion editing function using multi-level B-spline with quasi-interpolant. By using the proposed tool, we can make 3D animation easily and conveniently.

We developed an authoring tool for designing vibrotactile patterns quickly and easily by using the drag-and-drop paradigm in mobile devices. Designed vibrotactile patterns are registered into a data pool in the XML format, improving the reusability and extensibility of vibrotactile patterns. A multi-channel timeline interface is also incorporated to provide time-synchronized pattern editing for multiple vibration patterns (for multiple vibration actuators). In addition, an internal vibration player is embedded in the authoring tool in order to evaluate the patterns on the spot. A transform function for perceptually transparent vibration rendering can also be set in the editor. Although the authoring tool was developed for mobile devices, it can be used for other applications such as haptic interaction m virtual reality.

Most mobile devices such as smartphones and tablets have a soft keyboard implemented on the LCD touch screen to receive text inputs from the user. Because the size of the LCD screen is small, many efforts are going on to develop efficient soft keyboard with less key buttons. Especially, Hangul soft keyboard needs much time, effort, and deep software technology in developing an Hangul automata program module. This paper introduces design and implementation details of our authoring tool for Hangul soft keyboard running in Android. The tool supports the user to build an unique soft keyboard easily. The authoring tool downloads the soft keyboard app to the user's smartphone and makes it run immediately.

A smart phone has an error if we design games on it because smart phone should be able to have input and output simultaneously through the screen. Using the existing layout of the game as a base for research, the layout was divided to four categories that are information area, informational appearance area, operation area and inutility area. Given the research results, we developed an authoring tool to design games for smart phones. Moreover, we applied the authoring tool to develop games and effectively reduce the developing time.

This paper is about an authoring interface for augmented/mixed reality based book, specifically authoring 3D objects properties of Digilog book. We pursue even normal users with non-professional knowledge for programming can make the Digilog book easily. An authoring interface 3D object properties includes a manipulator as an input device and 3D contents authoring parts. As an interface design metaphor, existing GUI interface, already familiar to computer users, are referenced. The manipulator generates continuous/discrete input signal are necessary for authoring interface. Contents authoring part performs selection, positioning, scaling, coloring, copy of virtual objects using the input signal of the manipulator. Also users can exploit already existing GUI interface metaphor including pointing, click, drag and drop, and copy techniques with the manipulator. Therefore we think our AR authoring system can support rapid and intuitive modification of properties of virtual objects.

In this paper we propose a VR-based Sailor Training Platform Authoring Tool which efficiently trains sailors in immersive ways. Proposed authoring tool consists of virtual environment reconstruction that imports real ship indoor environment into virtual environment and script editing which is able to implement various scenarios in emergency based on just drag-and-drop interface. The aim of importing real ship environment and supporting various VR devices is to enhance immersiveness and training so that trainees can deal with serious emergency events. Also the usefulness of the interface enables to reduce the cost of making training materials. Throughout scenario editing interface, the proposed authoring tool supports the editing of multi-user scenario and setting individual task for the evaluation.

According to the increasing interests of medical information services for healthy living, the multimedia authoring tools for medical information service contents are strongly required. In this paper, a new multimedia authoring tool supporting user-friendly interfaces is implemented, which is based on SMIL(Synchronized Multimedia Integration Language) producing Web-based multimedia contents. The implemented authoring tool in this paper not only provides functionalities to play, verify and modify the partial contents immediately but also offers capabilities to insert multimedia objects into contents with ease. The multimedia contents containing disparate healthcare and medical information can be easily designed with this tool. The enhanced usability of this tool can contribute to the realization of diverse medical information services.

This paper analyzes the requirements of an ideal augmented-reality contents authoring tool that can allow non-programmers as content creators to author contents easily and quickly. To satisfy the requirements, we employ the approach using formal and visual specification techniques. In this paper, we also introduce an integrated augmented-reality framework for the ideal authoring tool, and demonstrate the effectiveness of our research results by illustrating an example content.

The population of consumers who purchase goods through electronic commerce(EC) is increasing due In the advance of Internet. They can purchase goods freely without time and space restriction and can have variety of choices of goods. Now most of e-Catalogs rely on the simple texts or images to present information on goods. As such, there is limitation in describing goods in detail, which might not make consumers interested in those goods. To solve the problem, more advanced e-Catalogs are demanded compared with the existing ones, requiring research on the e-Catalog authoring techniques that utilize dynamic multimedia data such as audios or videos in addition to the conventional texts and images. In this paper, we describe development of an e-Catalog authoring tnol that is based on SMIL(Synchronized Multimedia Integration Language) which is one of XML applications.
