To do this, study of human memory and theoretical approach on form in general is carried out to compare the types of memories and the stage of perceive theoretically to discover the relationship between psychological perceive and form. In the second please, scenario of form recognition in cultural aspect is studied through various written records to obtain unbiased critics on what a person can feel from a form through various analysis and experiment. Examples will be given on products designed on the basis of correlation with form through analysis. Through this procedure, elements of reactions on implicit and explicit is derived (Data obtained from experiments on computers and inquiries are used) Analyzed elements are than divided into, general knowledge, memories of reality and subconsciousness memories and basic mental image and user mental image and mental image of form of each products are analyzed. In the third phase, the way of adapting of the elements obtained from the analysis of implicit and explicit reaction to the field of design is predicted. Together with this, future theme this the study will be suggested. Confusions obtained from this study can be listed as below.

Technology Acceptance Model (TAM) has been widely used to predict user's behavior to accept the technology. Prior researches have been mainly focused on innovation constructs such as perceived usefulness and perceived ease of use. However, very little research has been conducted to understand individual mental beliefs in technology acceptance and imitation influence. This study integrates Technology Acceptance Model (TAM), Flow Theory (FT) and Diffusion of Innovation Theory (DIT). This paper indicates that imitation context, cognitive absorption (CA) based Flow theory and innovation context are the three important factors influencing user acceptance of information technologies. The proposed model has been tested among 232 users of MP3 players. Results showed that innovation context and cognitive absorption have positive influences on intention to use technology. Not all factors of the imitation context have direct effect on intention to use. However, we found that imitation context has positive influence on intention to use technology through cognitive absorption.

Recent development in science and technology has enabled vehicles to be equipped with advanced autonomous functions. ADAS (Advanced Driver Assistance Systems) are examples of such advanced autonomous systems added. Advanced systems have several operational modes and it has been observed that drivers could be unaware of the mode they are in during vehicle operation, which can be a contributing factor of traffic accidents. In this study, possible mode confusions in a simulated environment when vehicles are equipped with an adaptive cruise control system were investigated. The mental model of the system was designed and verified using the formal analysis method. Then, the user interface was designed on the basis of those of the current cruise control systems. A set of human-in-loop experiments was conducted to observe possible mode confusions and redesign the user interface to reduce them. In conclusion, the clarity and transparency of the user interface was proved to be as important as the correctness and compactness of the mental model when reducing mode confusions.

디지털 매체의 사용자들의 사용 모형이 변화하고 있다. RSS, 태그(tag), Ajax, Open API 등 사용자 참여를 향상시키는 Web 2.0 기술을 포함하여 정보 기기 및 인터페이스의 발전은 사용자들의 매체사용에 대한 범위와 역할을 크게 향상시키고 있다. 이제 사용자는 더 이상 정보수용자의 입장이 아닌 정보제공자의 입장에서 매체에 접근하고 있다. 이와 같은 현상은 우리에게 두 가지 중요한 연구문제를 제시한다, 첫째, 사용자들은 기술변화를 어떻게 인지하고 있으며, 어떤 학습의 과정을 거치고 있는가? 혹은 어떤 어려움을 겪고 있는가? 둘째, 변화하는 기술에 따른 사용자들의 요구변화의 양상은 디지털매체를 통한 정보제공을 통하여 수익을 발생시키는 기업의 사용자와의 상호작용을 어떻게 변화하게 하고 있는가? 이와 같은 연구문제를 해결하기 위하여 창조적 사용자의 인지적 모형을 점검하고, 차세대 기술변화에 따른 사회적 컴퓨팅의 진화를 근거이론을 통하여 분석해 보고자 한다.

Existing usability testing method, particularly lab-based usability testing, has been widely implemented for development of user interface. However, the method has critical disadvantages such as high cost, time and effort, unnatural testing environment, and lack of user's direct participation in information architecture. With these backgrounds, this paper aims to develop the web-based participatory tool with particular focus on card sorting. Our tool was developed for allowing user to participate in card sorting with his own computer through web. All the data generated while user is participating in the test are automatically sent to the server, which makes it very easy to collect card sorting data. Users can drag cards of interface elements directly and build the interface structure in their own from their computer-screen so that they can represent their mental models on interface structure of testing website. These functions of our tool can help designers to implement card sorting without tedious and time consuming procedures and improve the method of usability testing by reinforcing user's active participation in building an information architecture.

Today, the field that actively utilizes HMD, which is a representative implementation device of virtual reality, is game. We have frequently used interface design using metaphor to user interface of HMD based virtual reality game. The purpose of this study is to find out the metaphor types that appear in the game interface of the virtual reality FPS genre of HMD devices, which is a new medium. As a result of research, the metaphor types appearing on multiple interfaces have navigation, predictability-based, familiarizing, and physical world metaphor in terms of information perception and predictability-based and familiarizing metaphor in term of control action. It is considered possible to construct a correct mental model. It is expected that the stability-based metaphor to prevent user mistakes and the presentation metaphor to identify the identity of information space will be needed in the future.

Purpose: The purpose of this study is to propose useful suggestions by analyzing causal effect relationship between perceived usefulness (PU), perceived ease-of-use (PEOU), symbolic adoption (SA) which have four constructs, and ATCIS-II usage in mandatory context. Methods: Based on prior research, a research model was constructed using the variables of Technology Acceptance Model (TAM), the symbolic adoption theory, and the post-adoptive behavior variables. A structured questionnaire was conducted for those who use ATCIS-II in Republic of Korea Army (ROKA), and a total of 183 usable responses were collected and empirically analyzed using SmartPLS 3.3.9. Results: The results of this study are as follows; PEOU have a significant effect on PU and two constructs of SA (heightened enthusiasm, effort worthiness). PU have a significant effect on every construct of SA (heightened enthusiasm, mental acceptance, effort worthiness, use commitment). In addition, it was found that heightened enthusiasm have a significant effect on both expanded usage and exploratory usage. Also, mental acceptance and use commitment have a significant effect on exploratory usage. Conclusion: The findings of this empirical study have implications for proposing SA can explain mandated user's behavior and giving possible way that improve organization performance which adopt Information System (IS) by motivating end-user to extend IS's feature and explore new ways of using IS at work.

In software system development, an application interface is the main communication platform between human developers and applications. Interaction in any software application requires human's mental and physical activities. Although software systems have increased drastically in diverse sectors and many forms to quench human's needs and satisfactions, human always concern about the ease in usability of the software application so that it can be easily understood and navigated. Since many software developers still focus on the quantity of contents instead of the quality of the interface from the user's point of view, it is important to address human factors need in the early stage of the design and to continue addressing them during the entire stages of the software design for the persistent support of usability. In this paper, we propose the Modified Prototype Model (MPM), which helps the software designers and developers to design user-friendly software systems with easy-to-navigate interfaces by uncovering human factors in a convenient way. Moreover, we propose methods that assist to identify more human factors regarding software design. In this paper, we also study the implications of the proposed model and the proposed methods.
