The advancement of touch user interface technology is mostly due to the debut and success of the new user experience (UX), the iPhone. The introduction of Apple's iPhone especially made possible for the user experience to break away from the traditional input device of the mouse and keyboard. It is advancing from the current 3rd generation touch interface technology into the 4th generation non-touch user interface technology. This paper will present a non-touch interaction technology that allows interaction in a three dimensional setting through 3-D space touch. It will analyze current technologies and future emerging technologies.

Objective: This study is concerned with the user interface (UI) design of touch screen based on the reaction time of Automated Teller Machine (ATM) user. Background: Adopting the touch screen technology, the ATM service has recently established a new user interface different from the existing button-type interface. Method: Experiments were conducted by simulating ATM touch screen layouts, and layouts were focused on location of menu buttons (left and right, top and bottom), number of menu buttons (8 and 12 buttons). Results: The results show that there are significant differences in correction ratio and reaction time by user groups, types of menu location, and the number of buttons. Conclusion and Applications: The results of this study can be used to provide baseline information for the interface design of ATM touch screen and the age differences in reaction time.

Currently mobile phones possess the new features including the control interface provided with an ease, an intuition, and a variety and the display ensured for wide area. Mobile phones mounted with the touch screen release actively due to such strengths. This is the mega trend of the development of the latest mobile game. Mobile games set to the past keypad input system have changed for adaptation in the input environment and the progressive development. Consequently it is necessary to research for 'Touch User Interface(TUI)' of mobile games fixed into input environment by "Touch screen". This study have concreted the application method of touch game through the comparison analysis with the past game and implemented touch mobile game based on usability for ten touch mobile game titles released from the inside and outside of the country in oder to apply the touch interface fixed in the game to the hand-hold device with the function of touch interface. The result of this study have two implications. First it enhances the playability and diversity of game genre restricted by reason of the limitation of the past keypad input device. Second, it utilizes the basis for the standard of the interface of the touch mobile game by genre.

This paper proposes a novel touch interface for recognizing user's touch pattern and understanding emotional information by eliciting natural user interaction. To classify physical touches, we represent the similarity between touches by analyzing touches based on its dictionary meaning and design the algorithm to recognize various touch patterns in real time. Finally we suggest the methodology to estimate user's emotional state based on touch.

This study has been conducted on touch screen interface design for mobile devices. It was intended to measure user’s satisfaction on one-handed thumb input mobile devices. Recent studies proposed the optimal touch button size, but it is inappropriate for mobile devices. Therefore, this study was focused on four touch key factors-width, height, the horizontal and vertical distance between touch keys-as independent variables. The ANOVA results showed that the user satisfaction of four touch key factors was significantly affected by the thumb input. It also apparent that the interactions between four factors were significant. As a result, the horizontal and vertical distance as well as the width and height affected the satisfaction of users. In addition, this study suggested satisfaction models which represent the top 30%, 50%, 70% of user satisfaction measurement. The results of this study could be used to design touch keys that are able to enhance the usability on touch screen based mobile devices.

Currently many people are awfully concerned about smart device in domestic and foreign mobile market. The need of smart device has been rapidly increased. Unlike a feature phone smart devices provide us with an intuitive interface which is easy to control. They are enable to smoothly interact between user and device. Though higher market outlook, there is a lack of empirical research on user interface in touch screen based on smart device. In this paper, we propose the touch interface conceptual model concentrating on user based on the result of previous research. Materials of this research are three kinds of smart devices which are currently released. Through expert's depth interview and observation of user, user's cognitive actions in smart device are defined. Since the method of the touch interface which is suitable for the action has been derived, we have proposed the conceptual model of user's cognitive action. This research imply to offer the excellent design guideline in order to implement touch interface to optimize user experience in touch screen based on smart device to release in the future.

In this paper, a new touch user interface which is based on the hand operations of dragging and diversion is presented. With it, convenience and quickness for inputting of texts as well as searching and selecting of multi-layered menus are improved. The new interface also applies relative coordinate systems which display texts on the touch positions corresponding to the moving of touch location. It accommodates more text codes than those in conventional fixed coordinate systems which allocates texts to fixed location on touch screen. The suggested interface is implemented to IPTV remote control and set-top box to prove its practicality and effectiveness.

Touch interface is widely used in a smartphone instead of a keyboard or a keypad interface that has been adopted in a PC or a featurephone, respectively. Touch interface can recognize a variety of gestures that clearly represent the distinct features of each application's input. This paper analyzes users' gesture of each application captured by the touch interface of a smartphone. Specifically, we extract touch input traces from various application categories such as game, web browser, youtube, image and e-book viewer, video player, camera, and map applications, and then analyzed them. Through this analysis, we observed a certain unique characteristics of each application's touch input, and this can be utilized in various useful areas such as identification of an application user, prevention of running an application by an illegal user, or design of a new interface convenient to a specific user.

In this paper, we suggest a haptic interface and a framework of interaction with haptic feedback based Windows graphical user interface (GUI) in a computing device with touch screen. The events that occur during a user interacts with Windows interfaces through a touch screen are filtered out by the Windows Interface Message Filter (WIMF) and converted into appropriate haptic feedback information by the Haptic Information Provider (HIP). The haptic information are conveyed to users through a stylus-like haptic interface interacting with a touch screen. Major Windows interaction schemes including button click, menu selection/pop-up, window selection/movement, icon selection/drag & drop and scroll have been implemented and user tests show the improved usability since the haptic feedback helps intuition and precise manipulation.

With the development of electronic communication technology, the ship's navigational equipment is being digitized, and it has being studied touch-screen-based navigation user interface. However, due to the influence of environmental factors such as waves, it has a potential problem hazardous marine accident occurs due to incorrect operation, the systematic research in consideration of this be done do not. In this paper, we provide a user interface experimental model to verify the stability that takes into account the external environment of the touch-screen input on. Further, we simulated to verify that the interface of the touch screen, the effect of applying the input delay time and the size of the button is obtained through the experimental model proposed. It will be able to greatly contribute to studies of the interface robust touch screen user errors that can be analyzed by the experimental model is proposed to improve the ship, the overall system stability.
