This study investigates the user experience about the camera application and the operation environment that share the photographed pictures with the SNS in a smartphone user environment which is a necessity of modern people. To do this, 10 task tasks were selected based on 3 aspects such as manipulation, editing, and sharing, and the task execution time was measured after tasks were performed on 8 persons, 4 persons in 20s. Experiments conducted mainly on Samsung Experience 8 and LG UX 6.0, which are representative user interfaces of Android mobile operating system, showed that there are differences in usability between the three interfaces for each interface. In the course of the experiment, all of the subjects mentioned ease of operation and various functions as advantages. However, the complexity of text-based interfaces has been difficult to use because of the variety of functions that can be set up. Future research will be needed to improve the usability of camera applications by user interface.

A product labelling is one of key tools in ensuring that a patient uses drugs safely and effectively in self-care without professional support. This study aimed to explore the readability and comprehensibility of the information contained on two package inserts of medicines. Two package inserts were tested with first year college students. Fifty-one potential consumers underlined words they could not understand and answered 10 scenario questions. Any differences among groups with different characteristics were statistically tested. Secondly, the readability of two package inserts was assessed with comparison to the level of the 6th grade Korean textbooks. As results, more than 80% of participants properly replied to straightforward questions concerning indication, dosage, duplication, use in pregnancy and contraindication, and 73% about formulation. Less than half answered correctly in multiple choice questions about pediatric use (41%) and side effects (35%). Little discrepancy was observed in the comprehensibility between participants' characteristics. Drug inserts contained about 20% more professional-level words than 6th grade textbooks. In conclusion, Korean consumers may face challenges to understand drug information due to professional terminology and outdated expressions in the current package inserts. To secure safe and effective use of over-the-counter agents, greater efforts should be made to develop more consumer friendly labels. In the other hand, educational supports are required to prepare consumers in a proper level of knowledge for the safe use of drugs.

This research aims to propose an ergonomic design process for hip protector based on previous studies, existing products, multidisciplinary experts opinion, and wearing test. The elderly are more likely to suffer a hip fracture when they fall due to their physical changes in skeletal form, muscle quantity, bone density, and joint movement. A hip protector is an effective product to prevent hip fractures in the elderly but it also has a problem in that it is uncomfortable. Therefore there is a high chance that it won't be able to prevent hip fractures properly. Since the comfort of a hip protector is one of the most critical elements in preventing a hip fracture, we need to keep improving the hip protector for mobility and usability. Based on the previous studies and limitations of current hip protector products, we need to come up with an optimal design for the Korean elderly. First, knowledge has to be built relating to the ergonomic design of the hip protector considering body shape and size analysis using 3D-scan data, and biomechanical analysis on hip fracture. Second, we need to develop a design process including hip protector pattern design, and wearing evaluation with virtual system. Third, we suggest to reevaluate and verify the design procedure from impact evaluation using testing simulator, virtual evaluation of impact, to wearing comfort and usability evaluation. This design process presented in this study would be expected to contribute to the development of ergonomic hip protector which is suitable for the Korean elderly.

사용자-제품 상호작용(User-product interaction)의 관점에서 사용자의 만족도는 제품의 사용편의성(Usability)과 감성품질에 의해서 결정된다. 특히, 물리적으로 사용자와 제품의 기능을 연결하는 PUI(Physical User Interface)의 감성품질은 시각뿐 아니라 촉감, 동작감, 청감 등의 사용자의 다양한 감성의 조합으로 이루어져 있다. 문헌조사에 의하면, 사용자의 감성 만족도를 향상시키기 위한 제품의 시각적 감성품질에 관련된 연구는 활발하게 진행되고 있으나, 촉감, 동작감, 청감 등의 감성품질에 관련된 연구는 상대적으로 미흡한 실정이다. 이러한 관점에서 제품의 전체적인 감성품질을 평가하기 위해서는 제품과 사용자가 상호작용하는 PUI의 전반에 대한 사용자 만족도(User Satisfaction)의 정량적인 평가가 필수적이며, PUI의 감성품질을 구성하는 시각에 대한 고려뿐만 아니라, 예를 들어 조작장치를 잡는 느낌, 조작장치가 움직일 때의 동작감, 조작장치 작동 시의 청감 등 사용자와 조작장치 간에 일어나는 상호작용 전반에 관한 연구가 이루어져야 한다. 본 연구에서는 PUI의 구성요소 중 동적인 조작장치의 촉감, 동작감, 청감에 대하여 문헌 조사를 통해 조작 장치의 감성을 구성하는 요소들을 체계적으로 파악하였고, 감성의 요소를 중복 설명하지 않는 상호독립적인 의미를 가진 감성 형용사를 수집하고 분류한 후, 추출한 형용사를 기초로 설문지를 작성하였으며, 사용자들의 설문을 통하여 자료를 수집하였다. 구조방정식 기법을 사용하여, 조작장치의 전체적인 사용자 만족도와 촉감, 동작감, 청감 간의 상관관계 모형을 수립하였다. 또한 구조방정식의 결과를 바탕으로 인간공학 전문가와 제품설계 전문가로 이루어진 FGI(Focus Group Interview)를 실시하여 잡는 느낌, 동작감, 청감과 관련된 조작장치의 적절한 설계 변수를 결정한 후 설계값을 측정하였으며 감성 만족도와 측정치 간의 상관관계를 분석하여 감성품질 요소의 정량화를 수행하였다. 본 연구결과는 실제 산업현장에서 제품개발자들이 사용자 만족도에 영향을 미치는 제품 설계요소들의 상대적인 중요도를 평가하고, 감성품질을 결정하는 설계특성값을 구체적으로 파악하는데 실질적인 도움을 줄 것으로 기대된다.

We are suggesting an authoring tool can be used for prototyping in the augmented reality based product design environment. This tool is for authors without an engineering background to use. Our authoring tool can adjust the properties of visual, sound, and haptic feedback at the same time for more practical prototyping. Also the proposed modulated architecture can be applied flexibly to changes of platforms or hardware. Also user interfaces can be dynamically updated by changing just description files. finally, the suggested authoring methods exploit the advantages of both graphical and tangible user interfaces. Authors can intuitively make adjustments to many parameters using the TUI, and then they can do the same thing precisely using the GVI. The proposed authoring methods can be used for exhibition and entertainment contents using multi-sensory feedback in AR environment. As a future work, qualitative and quantitative usability test will be conducted.
