The purpose of this study is to evaluate the effectiveness of one-handed interaction modes for supporting the dead zone that users must be difficulty in performing the touch manipulation with only one hand. For the purpose, this study analyzed two existing one-handed modes in iPhone and Android smartphones, and proposed and implemented two additional one-handed modes. In order to investigate effectiveness of the one-handed modes, we performed the experiment that compared normal touch mode with the four one-handed modes. Experimental results showed that all one-handed modes required more time than normal touch mode because of the time requiring in both mode change and recognition. However, the participants had difficulty in manipulating continuous touches at dead zone area with only normal touch. Moreover, the subjective satisfaction was high in one-handed modes thanks to touch convenience and smooth transition effects in mode change. In special, the one-handed mode at iPhone was the most effective out of the tested modes.

In this paper, we suggest a haptic interface and a framework of interaction with haptic feedback based Windows graphical user interface (GUI) in a computing device with touch screen. The events that occur during a user interacts with Windows interfaces through a touch screen are filtered out by the Windows Interface Message Filter (WIMF) and converted into appropriate haptic feedback information by the Haptic Information Provider (HIP). The haptic information are conveyed to users through a stylus-like haptic interface interacting with a touch screen. Major Windows interaction schemes including button click, menu selection/pop-up, window selection/movement, icon selection/drag & drop and scroll have been implemented and user tests show the improved usability since the haptic feedback helps intuition and precise manipulation.

This paper considers the potential impact of biological approaches such as bio-copying (biomimetics) and biomanipulating (e.g. genetic engineering) on future developments in the field of textiles and, in particular, fibres. If analytical tools for studying biological systems combined with those of materials science are further developed, and higher efficiency and reproducibility of genetic engineering technology can be achieved, the potential for the copying and manipulation of nature for textile innovations will be immense. The present state for both fields is described with examples such as touch and close fastener, structurally coloured fibres, the Lotus of lect (for bio-copying), as well as herbicide tolerant cotton, insecticide resistant cotton (Bt cotton), cotton polyester bicomponent fibres, genetically engineered silkworm and silk protein, and spider fibres. (for genetic engineering).

This Paper presents some of challenges of creating feedback force, through manipulation of master manipulator, allowing the user to feel objects within a virtual environment. A sense of touch for the virtual environment. A sense of touch for the virtual environments was generated by a virtual compliance control method. In theis system data communication between the master and slave, we used TCP protocol. In the experiments. A position error between the master and slave arm was about $13.56^{\circ}$ in case that the master and slave arm had not compliance properties of the virtual object, while they have the its properties the position error reduced by $2.43^{\circ}$.

Touch-enabled technology is increasingly being accepted as a main communication interface between human and computers. However, conventional touchscreen technologies, such as resistive overlay, capacitive overlay, and SAW(Surface Acoustic Wave), are not cost-effective for large screens. As an alternative to the conventional methods, we introduce a newly emerging method, an optical imaging touchscreen which is much simpler and more cost-effective. Despite its attractive benefits, optical imaging touchscreen has to overcome some problems, such as heavy computational complexity, intermittent ghost points, and over-sensitivity, to be commercially used. Therefore, we designed a hardware controller for signal processing and multi-coordinate computation, and proposed Infrared-blocked DA(Dark Area) manipulation as a solution. While the entire optical touch control took 34ms with a 32-bit microprocessor, the designed hardware controller can manage 2 valid coordinates at 200fps and also reduce energy consumption of infrared diodes from 1.8Wh to 0.0072Wh.

In this paper, a new semi-automated cyber character generating method is presented. Local edge detection tools extract face contour from graphic image files. Some graphic manipulation process detailed touch to obtain neat face contour. This method shortens the making process dramatically while maintaining the good quality similar to real face image. Some of the processed images are illustrated for clear explanation.

With rapid development in ultra fast communication and digital multimedia, the realistic broadcasting technology, that can stimulate five human senses beyond the conventional audio-visual service is emerging as a new generation broadcasting technology. In this paper, we introduce a haptic broadcasting system and related core system and component techniques by which we can 'touch and feel' objects in an audio-visual scene. The system is composed of haptic media acquisition and creation, contents authoring, in the haptic broadcasting, the haptic media can be 3-D geometry, dynamic properties, haptic surface properties, movement, tactile information to enable active touch and manipulation and passive movement following and tactile effects. In the proposed system, active haptic exploration and manipulation of a 3-D mesh, active haptic exploration of depth video, passive kinesthetic interaction, and passive tactile interaction can be provided as potential haptic interaction scenarios and a home shopping, a movie with tactile effects, and conducting education scenarios are produced to show the feasibility of the proposed system.

Purpose: The benefits of the 'no-touch' isolation techniquethat is usually performed to prevent the circulation of tumor cells are not evident. The aim of this study was to determine whether the no-touch isolation technique for treating gastrointestinal cancers could prevent the circulation of tumor cells detected by reverse transcriptase polymerase chain reaction (RT-PCR). Matrials and Methods: By using RT-PCR to amplify mRNAs for two specific epithelial markers, carcinoembryonic antigen (CEA) and cytokeratin 20 (CK-20), we examined 34 gastric cancer patients who had been histologically diagnosed and 22 patients had undergone serosal and peritoneal brushing. Results: In 10 ($29.4\%$) of the 34 gastric cancer patients, we detected CK20 mRNA before manipulation, and in 17 ($51.5\%$) of those patients, after we detected it. The density of the CK20 mRNA band was increased in 11 cases ($33.3\%$) and the density was decreased in 2 cases ($6.1\%$). In 16 ($48.5\%$) of the 34 gastric cancer patients, we detected CEA mRNA before manipulation, and in 17 ($51.5\%$) patients after we detected it. The density of the CEA mRNA band was increased in 8 cases ($24.2\%$) and decreased in 3 cases ($9.1\%$). Conclusion: These result suggest that the ' no-touch isolation technique ' might be useful when operating on advanced gastric cancer patients and that serosal or Douglas pouch brushing can be used to determine the status of micrometastasis.

This paper describes a multi-scale user interaction based tiled display visualization system using multiple input devices for monitoring and analyzing Geostationary Ocean Color Imager (GOCI) observation satellite imagery. This system provides multi-touch screen, Kinect motion sensing, and moblie interface for multiple users to control the satellite imagery either in front of the tiled display screen or far away from a distance to view marine environmental or climate changes around Korean peninsular more effectively. Due to a large amount of memory required for loading high-resolution GOCI satellite images, we employed the multi-level image load technique where the image was divided into small tiled images in order to reduce the load on the system and to be operated smoothly by user manipulation. This system performs the abstraction of common input information from multi-user Kinect motion and gestures, multi-touch points and mobile interaction information to enable a variety of user interactions for any tiled display application. In addition, the unit of time corresponding to the selected date of the satellite images are sequentially displayed on the screen and multiple users can zoom-in/out, move the imagery and select buttons to trigger functions.
