The importance of User Interface (UI) in mobile phone has increased as the complexity of use increases due to the new technology adoption. The complexity and load for user interface development has increased accordingly. This paper discusses how to make a structured UI development process based on the mobile phone UI development case. After the review of UI development process and issues arising during the development, four levels of user interface guidelines are proposed such as macro rules, action templates, application rules and interaction cases. The importance of dealing various interaction case is emphasized which is not referred in the present industry UI guidelines. Most of research related to UI development focus on the target product rather than how to make good UI process. Based on the good UI process, good UI of the product can be realized. This proposed process based on UI guidelines will help to step up the UI development of mobile phone industry. Also, this process can be applied to different products or services.

Diverse operating systems and developed platforms of mobile devices are implemented by vendors exist. The software has to be developed by respective environment in designing the user interface of software. For the solution of the inconvenience, this paper proposes an integrated platform 4A DUOS for developing user interface independently. The proposed platform can use web language not dependent on various operating systems, and offer online access to API and component templates to provide the convenience of the user interface design. Also, the server with on board designed user interface implements the service to the user. Therefore, the users can design the independent user interface on various mobile devices by using only one source.

The design functionality put forward by mapping the interactiveness of information. The presentation of such information with the user interface model indicates that the guidelines, concepts, and workflows form the deliverables and milestones for achieving a visualized design, therefore forming the right trend is significant to ensure compliance in terms of changing consideration and applying evaluation in the early stages. It is evidenced that prototype design is guided by improvement specifications, includes modes, and variables that increase improvements. The study presents five user interface testing methods. The testing methods are heuristic evaluation, perspective-based user interface testing, cognitive walkthrough, pluralistic walkthrough, and formal usability inspection. It appears that the five testing methods can be combined and matched to produce reasonable results. At last, the study presents different mobile application designs for student projects besides the evaluation of mobile application designs to consider the user needs and usability.

As a result of the growth of mobile devices such as PDA and cellular phone, a user can utilize various digital contents everywhere and anytime. However, mobile devices have the limited resources and interaction mechanisms. This paper introduces the schema for a user activity estimation and its application in order to overcome the poor user interface and limited resource problems. We are able to supplement lacking the user interface of mobile devices by using the user activity estimation proposed in this paper, and its application is a intelligent control interface for the display power on or off which can effectively utility the battery of the mobile device.

We present the initial results of on-going research for building a novel Mobile Haptic Interface (MHI) that can provide an unlimited haptic workspace in large immersive virtual environments. When a user explores a large virtual environment, the MHI can sense the position and orientation of the user, place itself to an appropriate configuration, and deliver force feedback, thereby enabling a virtually limitless workspace. Our MHI (PoMHI v0.5) features with omnidirectional mobility, a collision-free motion planning algorithm, and force feedback for general environment models. We also provide experimental results that show the fidelity of our mobile haptic interface.

A touchless user interface system is proposed for real-time mobile devices in this work. The proposed system first recognizes the position of pattern to interact various applications based on the scene taken from mobile camera. Then, the proposed system traces the route of the pattern, which estimates the motion of pattern based on the mean-shift method. Based on this information, we control menu and keypad for the various applications. Differ from other user interface systems, the proposed system provides the new experience to even for the user of low-end mobile without additional hardware. Simulation results demonstrate that the proposed algorithm provides better interaction performances than the conventional method, while achieving real-time user interacting for mobile devices.

The purpose of this study is to find out the important factors and efficient strategies concerning fashion mobile marketing. This study contributes to the effect on shopping behavior of m-commerce consumer applying technology acceptance model(TAM) in the mobile fashion merchandise shopping environment. The areas of study interest are mobile commerce interface characteristics, flow, perceived usefulness, ease of use, attitude, purchase intention. To fulfill the study objectives, a total of 406 questionnaires were conducted to the customers with first-hand experience with merchandise in mobile commerce. The judgement sampling method was employed on sample population ages from 20s to 30s over two month period. Based on the results of the above-mentioned path analysis, The result showed that different factors affect acceptance intention of the fashion M-commerce. The result which extended TAM relationship, excepted affects in perceived ease of use by navigation and Flow, perceived usefulness by perceived ease of use and purchase intention by perceived ease of use considers from all relationships the effect put out. On this wise, mobile commerce interface characteristics needs provider of basic contents to fashion mobile commerce technology acceptance and suggested the ability which diffuses a fashion mobile transactions.

Recently, wireless multi-networking technology has been studied for supporting multi-interface in mobile node. As the related work, in the IETF NetExt WG, the extension of Proxy Mobile IPv6 protocol for supporting flow mobility is actively on going in discussion. PMIPv6 protocol supports simultaneous access through the multi-interface in a mobile node and inter-technology handover between multiple interfaces. However, this protocol can not support flow mobility. Thus, in this paper, when a mobile node connects to PMIPv6 domain through multi-interface, as a way to support flow mobility, the design of logical interface and Home Network Prefix change scheme based on logical interface are proposed, We show that the proposed scheme can perform flow mobility service without end-to-end disconnection in PMIPv6 domain.

The objective of this study is to quantitatively incorporate user observation into usability evaluation of mobile interfaces using monitoring techniques in first- and third-person points of view. In this study, an experiment was conducted to monitor and record users' behavior using Ergoneers Dikablis, a gaze tracking device. The experiment was done with 2 mobile phones each with a button keypad interface and a touchscreen interface for comparative analysis. The subjects included 20 people who have similar experiences and proficiency in using mobile devices. Data from video recordings were coded with Noldus Observer XT to find usage patterns and to gather quantitative data for analysis in terms of effectiveness, efficiency and satisfaction. Results showed that the button keypad interface was generally better than the touchcreen interface. The movements of the fingers and gaze were much simpler when performing given tasks on the button keypad interface. While previous studies have mostly evaluated usability with performance measures by only looking at task results, this study can be expected to contribute by suggesting a method in which the behavioral patterns of interaction is evaluated.
