This experimental research explores the effect of low attention of movie audience on the experience of presence, the degree of emotional touch, and memory about movie contents, because of indiscreet use of smart phone. This study measured and analyzed the experience frequency of presence, degree of emotional touch and recognition memory about movie contents by self report survey, after showing 2 subject groups consisting of 83 University students, one with not manipulated attention, the other with manipulated attention, using smart phone intentionally. This research found that the subjects exposed to the movie with not manipulated attention showed more presence experiences, and higher degree of emotional touch than the subjects exposed to the movie with manipulated attention. However meaningful difference of recognition memory was not discovered between the 2 groups. The result of this research can have a meaning because proceeding studies about presence effect of movie mainly dealt with the effect of HDTV, 3D image, stereo sound on the experience of presence, arousal, pleasure of movie audience and it is difficult to find studies about the relation between attention of movie audience and the experience of presence, emotional touch, and memory.

In this paper, we have developed a module that prevents a driver from using mobile phone while driving. The module is equipped with a vibration sensor to determine if the vehicle is running, a BLE module to transmit the status of the module and a speaker to transmit audible/unaudible sound to the mobile terminal where GUI application is installed. If the vehicle is judged to be moving, the application is activated and the touch function of the mobile phone is blocked. Other data are also transmitted depending on the state of the module, which informs forced module removal, battery failure, or sleep mode of the module.

The purpose of study was to evaluate effects for repetitive use of thumb according to two different input types (button and touch) of mobile phones. A total of eight young and healthy subjects (6 males and 2 females: $24.63{\pm}8.04$ years) volunteered, and force measurement on thumb using film type pressure sensor was carried out for an hour. Before the experiment De Quervain's syndrome test were performed to check the left and right muscles related with thumb motion and after measuring the pressing force fatigue feeling survey achieved. For a statistical analysis, 1-to-5 ranking scale was used to score the fatigue feeling. From the result of pressure measurement, forces acting on thumb in button type were 3.36 times (the right thumb) and 3.16 times (the left thumb) for the touch type. And the result of survey, fatigue by using the button type of mobile phone was largely triggered than by using touch type. The abductor pollicis brevis and the flexor pollicis brevis were found as common part of fatigue for repetitively using thumb during texting messages. In the further study, some quantitative fatigue comparisons for various input motions are required to analyze repetitive strain injury syndrome.

Though the spread of the touch screen devices is now revitalized, the Korean input methods in the touch screen devices are mostly the button input methods using keypads. Even though the button input methods are used with a touch screen, they still adopts the existing qwerty keyboard. It means that the existing methods can not be improved. This research suggests that the Korean input method which can be used in the portable terminals and the touch screen devices, for example, a smart phone which has a limited sized screen. It assigns every vowel a process which corresponds with the Korean invention theory and the vowel input method is to drag it. Through the mock experiments, we confirmed that the simplification of the Korean alphabet is more efficient than the existing methods, in the point of the speed of the Korean input.

Currently many people are awfully concerned about smart device in domestic and foreign mobile market. The need of smart device has been rapidly increased. Unlike a feature phone smart devices provide us with an intuitive interface which is easy to control. They are enable to smoothly interact between user and device. Though higher market outlook, there is a lack of empirical research on user interface in touch screen based on smart device. In this paper, we propose the touch interface conceptual model concentrating on user based on the result of previous research. Materials of this research are three kinds of smart devices which are currently released. Through expert's depth interview and observation of user, user's cognitive actions in smart device are defined. Since the method of the touch interface which is suitable for the action has been derived, we have proposed the conceptual model of user's cognitive action. This research imply to offer the excellent design guideline in order to implement touch interface to optimize user experience in touch screen based on smart device to release in the future.
