In this hi-tech world, privacy is most important issue. Has anyone ever imagined why this problem arises? In the field of correspondence media or portable correspondence, web association is a spine of data and correspondence innovation which gives numerous administrations to client to these applications we need quick and headway of Internet integration innovation and vast range of channels[1]. Internet access speed or whether it is about downloading files, internet speed is big issue. Why not take a step further to resolve this problem? The answer to our problems is 'li-fi'. Have you ever wondered a city where internet access is wireless and without any interruption? Like other queries science has an answer to these questions also which is LIFI. LIFI is the new future. From sharing data to accessing it, can be done for laptops, smart phones, and tablets through transmitting light from LED bulb installed within the room. And for the security, if you can't see the light, you can't access the data[2].

In the era of aging society in China, focusing on the issue that it is difficult for elderly people to operate a variety of computing devices with the physiological and psychological changes brought by the aging, a research for ergonomics of interactive devices was put forward for elderly user groups. The research studied the performance of elderly people using the mouse, stylus and touchscreen to perform two-dimensional pointing tasks, compared with younger people, in the computer user interface by controlled experiments, measured the movement time and hit accuracy, and also investigated the subjective experience when they used the three input devices for completing two-dimensional pointing tasks. Experimental data analysis showed that elderly people spend more time than younger people to complete the pointing tasks with any of the three input devices, Fitts' law still hold when the elderly people used mouse, stylus and touchscreen to perform the two-dimensional pointing tasks, and the use of touchscreen can achieve higher performance with the target size should not less than 80 pixels (about 11.2 mm) for both elderly and younger people. Elderly people can benefit more from the touchscreen than younger people.

Smoke simulation is an interesting topic in simulation fluid dynamics and graphics area. Stack Effect Fire model was happened in fire of High Rise building. Simulation this fire model and smoke scene is one of the most challenging tasks in fluid dynamics of computer graphics area. In this paper proposed Smoke simulation rendering is based on game engine of particle system. But common game engine don’t have stack effect model and compute coordinate position algorithm. Recently proposed method based on FDS’s (Fire Dynamic Simulation) result Excel file which improves Unity 3D game engine for stake effective fire model and smoke boundaries. Using Excel file coordinates to improve Unity 3D game engine particle system, and changes the original game engine particle system, over the coordinates of particles moving location, boundary and fire model stake effect look like real world fire model. Recently game engine computer graphic researcher usually control computing resources focused on smoke visualization skip fire effect and physically problem. In this paper, need focused on smoke location boundary and fire model stake effect. The proposed method can change smoke and fire model of stack effect and particles more accurately and efficiently than other, rendering is implemented by making smoke particles and physically effect. After putting the coordinate form FDS into Unity3D game engine Experiment performance result shows particles more look like reality, and gives neutrality and reality to user's view. This algorithm problem is from simulation high rise building mesh with loading time need more computer resource, and need to change some effect in Unity 3D game asset.

Carl Gustav Jung affirms that mandala is the real-life image of core prototype in his famous prototype theory. Mandala comes from the psychological diagram of the one with great achievements in Buddhism; it’s represented as paradigms composed by certain plane which provides an opportunity for various subjects related to graphic art in exploring the core prototype issues. This paper explores the revelations and application thought from mandala in the design methods of architectural prototype on the basis of some philosophical connotations in analytical psychology and Chinese traditional culture, and attempts to develop a design method of architectural prototype with infinite development possibility.

In this paper, we propose an intelligent system, called “Mobile Fashion Advisor”, aimed to create a virtual fashion assistant to give suggestions on the usage of clothing and help users avoid buying clothes that are never worn. Many different computer theories and techniques are exploited in the system. Digital image processing techniques, such as edge detection and color histogram, are employed to obtain the essential data of garments. Fuzzy theories are applied for gathering fashion matching rules. Users can simply use a smart phone to take a photo of the garment when shopping and submit it to the clothes server through ubiquitous network.Then Attire Scheme Harmony Evaluator follows match rules to search whether there are clothes in her personal garment database that matches the new one. The results of matching and grades of whether to buy are sent back and shown on the phone. The work is to provide such a user-centric services system that functions as a personal fashion advisor for clothes shopping.

Efficient cooling methods are necessary when living in a tropical climate where high temperatures and high humidity are normal. Air-conditioning units, which are expensive to run and maintain are standard in a majority of houses in Australia's tropic zone due to the design of both historic and modern housing not being fully suited to a tropical region. Significantly, the cost of energy consumption continues to increase. There are simple and inexpensive modifications a homeowner can do to naturally cool the house and preserve energy, such as, painting roofs white, planting screening vegetation and installing shades externally to cover windows, etc. However, many of these alternative techniques are not common knowledge and are not presented to the public in ways that can inform and potentially change behaviour. This paper presents a housing simulation prototype that applies gamification methods to build awareness on ways to reduce cooling power consumption. An interactive guided persuasion methodology is used to educate homeowners about these alternative techniques so they may choose natural cooling methods instead of relying on electrical cooling appliances. The results of the user testing show the simulation design did encourage awareness and motivation to make tangible adaptations to homes.

There has been a surge in the intelligent content services in the broadcasting and communication sectors as the convergence between the contents of various industries and highly-advanced IT is gathering momentum. As a result, the users can conveniently save, distribute, and disseminate the converged contents using the smart devices that have independent platform. However, there is technical limit in achieving the continuous replay after freely converting the single content via the independent devices. Furthermore, children and adolescents are easily exposed to violent and explicit contents amid the growing distribution of smart devices. In this paper, we suggests the OSMU (One-Source Multi-Use) management framework that ensures the fast and convenient use of one single content via the heterogeneous device and the integrated content management that enables the distribution of contents by grade.

The Smart Cross Platform is a virtual machine based solution that supports various programming languages and platforms, and its aims are to support programming languages like C++, Java and Objective-C and smart phone platforms such as Android and iOS. Various contents that developed by supported language on the Smart Cross Platform can be execute on Android and iOS platforms at no additional cost, because it has the platform independent characteristic by using SIL(Smart Intermediate Language) as an intermediate language. In this paper, we will introduce a Java compiler for the Smart Cross Platform to support Java contents. Proposed compiler translates given Java programs into stack based intermediate SIL codes to execute on the SVM(Smart Virtual Machine). Thus, existing JVM’s contents can be easily ported and executed on the Android or iOS with SVM.

As the growth of the Internet has given consumers an access to unprecedented amounts of digital contents from almost anywhere, thanks to a variety of smart devices, it has raised concerns about the safety of personal data with current digital content transaction model when purchasing the online digital contents. Smartphone use is increasing rapidly and it is affecting every aspect of people’s lives and working environment. Thus, smartphone has become an essential personal tool and individuals have much dependence on it. We examine the security issues of smartphone and smart work environment in terms of describing the threats and problems with respect to privacy information protection. In order to solve this problem, we propose a transparent and reliable online distribution infrastructure system equipped with improved protection of consumer rights, supplier revenue, and enhanced prevention of copyright infringement. To be precise, this secure digital content transaction system enables N-screen based consolidated authentication model from various smart devices to process transaction confirmation anonymously so that consumer’s personal information can be protected. In addition, this anonymous authentication technology between user and service provider also allows possible security threats to be traceable by using traceable anonymous technology.

Unicode 6.1 (2012) had encoded more than 74,000 Han characters. This great repertory could solve the problem of unencoded Han characters to a significant extent. However, most information systems today still only support input and display of the first 20,902 encoded Han characters in Unicode 1.0 (1991). Even in latest systems, designed to support 32-bit Unicode and with suitable fonts installed, it is not easy to use these newly encoded Han characters. We note that many of these newly encoded Han characters are rarely used in users’ everyday life. An ordinary user may have confusions of their glyph shapes, pronunciations, meanings, and usages. IMEs (input method editors) for Han characters usually require users to have good knowledge of wanted Han characters. It is not unusual users try but fail to input unfamiliar Han characters. In this paper, we present an auxiliary Unicode Han character lookup service by radicals. One can use any Han character IME to key in one or more radicals to look up a wanted Han character. Every Unicode Han character is decomposed as a glyph expression of radicals. The similarity between the glyph expression and user input is estimated by a derived edit distance algorithm. The most similar Unicode Han characters are returned. As a result, the system provides users a convenient way to look up unfamiliar Unicode Han characters.
