The rapid development of the mobile internet has gradually changed the carrier of electronic games from PC to mobile. mobile games have become an excellent choice for many people to spend their spare time and enjoy life. Among many types of mobile games, Number of users of FPS games has increased rapidly in recent years. Based on the 《Emotional Design》 proposed by Donald Norman, this article compares the interaction design of China's most popular FPS game 《Game for peace》 and Korea's most popular FPS game 《PUBG》, and analyzes their similarities and differences, and then use that as a basis to summarize the three levels of emotional design-Visceral level, Behavior level, and Reflection level, which is the user interface, interaction mode, and interaction experience in interaction design Emotional expression on the two games. This theory provides suggestions for interactive design in the information industry such as mobile games.

In the future, smartphone convergences are not only based on the on/offline integration, but also with the integration between mobile communications and broadcasts. Therefore, there is a need to search for new direction of mobile device that enables variety user applications that are different from the existing size and application issue. The aim of this reserch is to improve user interface of smartphone's functional attribute. The survey results in this paper showed that the most preferable attribute of smartphone among the 8 was the wireless internet 25.3%, followed by messaging 20% and application 19.8%, which totaled to 62.5%. But the samples used were mostly limited to those aged 20 through 30. So the results are not considered as a representative preference of all smartphone users, and should be considered otherwise before materializing them to a product. Therefore, for the more liable results the further research should be conducted to gather data from a variety of users of all ages, and the functional attribute should be analysed through QFD.

In this paper, we propose the CRM service model for analyzing and managing location based data collected by Wi-Fi and BLE. As mobile devices became personalized, enterprises became interested in individual location, and location based mobile marketing started to stand on spotlight. Location based proximity marketing is developing along with contactless data transmission technology, and payment system that uses NFC, Beacon that utilizes BLE, as well as advertisement via Wi-Fi are being serviced. We suggest the model that mobile devices can be detected and identified by MAC address with the need of being connected to Wi-FI or Bluetooth interface. MAC addresses are not associated with any specific user account or mobile phone number. The idea is to be able to measure the amount of people which are present in a certain point at a specific time, allowing the study of the evolution of data analysis and offers effective information for decision-makings.

Mobile shooting games are a representative example of PC games being transferred as they are. In the most mobile shooting games, joystick-like UI used in PC games have been moved to touch buttons, but the display is small, so the user's fingers cover the game screen, which is inconvenient. In mobile shooting games, in order to overcome the limitations of the small display and increase the immersion of the game, this paper introduces a user interface that integrates character movement and aiming, and intuitive UIs such as display rotation, shaking, and vibration. In addition, by analyzing the match process for each round, the character's insufficient abilities are identified and synergies to supplement the abilities are recommended in order to add fun to the game. This paper proved that the proposed goals are achieved by actually designing and implementing a mobile shooting game with the proposed functions on an Android smartphone.

Computing systems in the modern era are expanding rapidly to include mobile-based businesses that make us of the various convergence distributed business process. This has lead to growing interest in the field of mobile embedded software development methodology, which has in turn lead to the proliferation of the embedded mobility. The use of CBD (Component Based Development) provides reusability, maintainability and portability, all of which are very important and focus issues to the business process. It also comes with the inherent productivity, quality and reliability of CBD. To make efficient use of CBD, though, clarified interface definitions for component integration are necessary. These definitions should be made up of collaborative hierarchical and horizontal architecture layers. Successful definitions should apply an effective framework made up of the architecture and process. In this paper, we describe an interface specification for small grained mobile embedded components(MEC) for the mobile embedded domain to meet maximum user requirements. We build and deploy the reconfigurable design patterns and components (in business domain categories) to make a component hierarchy and business logics for mobile embedded software. Proposed components specification plays a major role in development of the software for handling inconsistency in existing specification. It also includes plenty of specification information, using semantics and modeling based mechanisms to support business processes. We propose a development model of mobile embedded software using CBD for very complex and dynamic mobile business. We can apply it in a plug and play manner to develop the software. We verify that our framework supports very good productivity, quality and maintainability to meet the user's requirements in mobile business.

With the rapid growth of smart phone technologies, mobile user's demands for using services provided by existing web or portal cites are highly increased. These services, however, are designed for the environment of desktop PCs or laptops in general, so it requires lots of costs for corrections and has difficulties for system protection to use in current mobile devices. In this paper, we design and implement a middleware for android-based smart phone apps to cooperate with a portal system with minimum corrections and function configuration. Our middleware system is working as an interface between an existing portal system and mobile devices to provide harmonious usage and safe system protection.
