  • 모바일 기승의 발전으로 기존 PC 화면 기반으로 개발된 기능들이 모바일의 작은 화면으로 옮겨짐으로 인해 큰 화면의 정보를 작은 화면에 동일하게 표현하기 위해서 모바일 기기 화면상에 많은 가로 스크롤이 발생하게 되었다. 가로 스크롤로 인해 모바일 기기의 작은 화면으로 문서를 읽을 때 현재 읽고 있는 줄의 위치를 놓치는 오류가 발생하게 되었으며, 이러한 줄 이탈 오류로 인해 문서의 가독성이 떨어지게 되었다. 본 논문에서는 모바일 기기의 가독성을 높이기 위해서 Line Marker를 제안 하였으며, 실험을 통해서 Line Marker가 없는 조건, 이동하는 Line Marker 조건, 고정된 Line Marker 조건에 따른 문서의 읽기 속도와 읽기 방식에 따른 만족도를 평가하였다.

  • This thesis focuses on the 3D interface tab page type and mode of screen that affect the usability of the small screen devices such as smartphone. The experiments examined eight 3D UI designs, combinations of two modes (Portrait, Landscape) of screen, and four types (Vertical data mountain, Horizontal data mountain, Vertical carousel, Horizontal carousel). Twenty-six participants participated in the experiment. The completion time, preference and fun score were measured. The results showed that the vertical data mountain type provide the best performance in terms of the all conditions. The results of this study suggest a practical approach for the 3D UI tab page design for the small screen devices.

  • In this paper, the light screen sensing system is introduced and testified to detect small grains such as seeds or electronic chips of uneven sized. Two modules composed of transmitter-receiver sensor array and microprocessor-based sensor signal processing system are developed to realize the proposed system. Experimental results showed that the sensing signal was relatively clear and its counting performance was very stable.

  • Mobile web applications are different from desktop web applications because of their small screen size and small user input devices. Therefore user interface designers have spent their effort and time to re-design the user interface of mobile web applications to meet these differences. In this paper, we introduce five user interface patterns for mobile web applications to reduce their effort and time. Two of them are for utilizing small screen size efficiently, and they are space overloading pattern and data filtering pattern. These patterns enable designers to reduce screen usage. The other three patterns - data suggestion pattern, input reuse pattern, and incremental data input pattern - are for helping users' data input on mobile devices. These three patterns enable users to reduce direct data input. Our work will help user interface designers develop mobile web interface to utilize screen space efficiently and get data with less errors and less efforts from users.

  • Mobile internet access using such devices as PDAs and cellular phones becomes popular as mobile technologies grow. However, the characteristics of small screen devices such as small screen size and pen-based input cause many usability problems. In this study, a human factors experiment was conducted to identify the factors affecting the usability of information search on a PDA. Factors manipulated in the experiment included use of wheel equipment, scroll dimension, and screen orientation. Task completion time, error frequency, and subjective satisfaction level were measured. In addition, various users' behavioral patterns such as scanning routes and mainly used scrolling methods were analyzed. Scroll dimension has a significant effect on task completion time. Scroll equipment and screen orientation affect subjective satisfaction level. The results could be applied to designing information structure of web sites for mobile use by providing vertical scroll and using external scroll equipments.

  • The double layer screen plate tensioned with two sheets screen mesh is more thicker than that of one screen sheet. The double layer screen plate piled up with two sheets screen 200# or overlapped with a sheet screen 110# and a sheet screen 305# is more thicker than single layer screen plate with one sheet screen 420#. As the screen plate composed of two sheets screen has more accumulated ink capacity than one sheet of screen, printing printed with it has a good plasticity. And the single layer screen plate that accumulate a small quantity of ink has an excellent representation than the double layer screen plate but lower plasticity.

  • Small-screen mobile terminals have difficulty accessing existing Web resources designed for large-screen devices. This paper presents an adaptive transformation method based on webpage semantic features to solve this problem. According to the text density and link density features of the webpages, the webpages are divided into two types: index and content. Our method uses an index-based webpage transformation algorithm and a content-based webpage transformation algorithm. Experiment results demonstrate that our adaptive transformation method is not dependent on specific software and webpage templates, and it is capable of enhancing Web content adaptation on small-screen terminals.

  • The fog screen is a device projecting the media to the aerosol flow field. As major parameters to generate dense and steady fog screen, shear stress, optical blockage ratio and SMD were obtained result through experiment. The micro droplet was generated by the piezo oscillation element, and the aerosol flow mixed with an air flow was sprayed into the vertical direction from the top of the fog screen through the 280 mm slot. For produce a dense, uniform fog screen, the shear effect, optical blockage ratio and SMD between aerosol and air curtain were measured. The minimum and maximum shear stress conditions were selected and it was confirmed that the optical transmission deviation of the aerosol flow field was small when the aerosol and air curtain flow rates were changed. When the aerosol and air curtain flow power were 18 V (1.51 m/s) and 24 V (2.55 m/s), respectively, under the condition of the minimum shear stress and laminar flow, the optical blockage ratios with the spray length were small, and it produced a most stable and high density uniform fog screen by injecting a constant of $10{\mu}m$ or less.

  • In this study, theoretical super screen vibration analysis has been carried out to predict the dynamic characteristics of interactive waste particles. In order to approach these problems, it is necessary to have a fundamental understanding the screening process and the process of both the remaining and the passed material on a screen with several interacting screen planes based on Soldinger(1999) was discussed. Here, the vibrating screen is composed of three assemblies such as screen, wastes guide, and supported screen as shown in Fig. 1. This model is regarded vibrator as the system of screen fixed tilt plates. Then materials(or particles) of different size is to be separated by using the eccentric vibrator and classifying tilt plates. As well moisturized construction wastes is more efficient to separate than moisture-less it. In processing separate mechanism, the more materials is light, the more staying time is long. Thus much lighter construction wastes(wood, Styrofoam, etc) and heavier materials are separated by staying time delay in a super screen. The design results, separation screen were able to know that small and larger particles are conspicuous difference each motion character according to trajectory particles, and small particles raise the probability in classifying tilt plates.

  • This paper presents the development of smart counting system that is proper for grains with uneven unit weight or shape. This device can detect the small differences of a light beam and count the pulse from wave shape control, when the grain is going on the light screen, which is made by the light beam screen sensor. It can, different from the former conventional device, distinct the uneven grains for counting detect, by using the dedicated hardware and the software algorithm of the light sensor.
