  • Most people with visual impairments can not use both hands freely because they carry a cane. And unnecessary contact with people around you during walking can occur. Other guides include guide dogs, but the price and maintenance cost are expensive and difficult to manage. In this paper, we propose a smart glove, which prevents unnecessary contact when blind people use the cane, detects the obstacle ahead by using the ultrasonic sensor, and informs the presence of the obstacle by using the servo motor. In addition, the electrostatic proximity touch module on the fingers executes a specific application of the smart phone connected by Bluetooth when the finger touches each other. It is designed to allow you to use text or phone calls when you are lost or in an emergency. The results of this study will be used as a tool to provide a more convenient life for the visually impaired.

  • Recently, Smart Home System(SHS) is applied in order to provide comfort, energy efficient and better security to the residence. Thus, by introducing the SHS in the house of elderly people, it is possible to provide a convenient and safe life for old people especially living alone. This paper presents the design and implementation of a low cost but yet flexible and secure smart-phone based SHS. The design is based on inter-working between Arduino board with Bluetooth and Arduino board with Ethernet shield, and the home monitor/appliances are connected to the input/output ports of this board via sensors/relays. In addition, when the old man is put on an emergency, the proposed system will automatically notify it the family. Therefore, we have implemented an inexpensive and efficient SHS for the elderly living alone by inter-working smart phones, internet server and Arduino micro-controller.

  • Purpose : Dental trauma is frequently unpredictable. The initial assessment and urgent treatment are essential for dentists to save the patient's teeth. Mobile-phone-assisted teleconsultation and telediagnosis for dental trauma could be an aid when a dentist is not available. In the present in-vitro study, we evaluated the success rate and time to transfer images under various conditions. Materials and Methods : We analyzed the image quality of cameras built into mobile phones based on their resolution, autofocus, white-balance, and anti-movement functions. Results : The image quality of most built-in cameras was acceptable to perform the initial assessment, with the autofocus function being essential to obtain high-quality images. The transmission failure rate increased markedly when the image size exceeded 500 kB and the additional text messaging did not improve the success rate or the transmission time. Conclusion : Our optimal protocol could be useful for emergency programs running on the mobile phones.

  • Recently, as the smart phone market grows explosively, there exists a large difference of utilization of the smart phone between an usual people and the visually impaired people. In this paper, We propose the character and numer ic input system based on the low cost of braille film and braille for the visually impaired people in order to reduce to information literacy gap for the visually impaired people. The proposed system is designed with the braille film and keyboard layout based on the braille character layout. Additionally, the telephone, the SMS, the abbreviated dial and location transfer function for the emergency situation are designed. The character which inputs using the braille keyboard can be automatically copied in the clip board and used in the other applications. Hence, the visually impaired people can easily use the smart phone for getting plentiful information on the device and network.

  • This paper presents the mobile phone case for self-power generation and recharge for emergency calls or text messages at the discharge of a battery. If the user shakes his smart phone case, the interaction of electromagnetic coil and permanent magnet in an electric generator produces electric energy, which charges the lithium-ion battery. This enables the user to give a few calls or text messages. In addition, the vibration energy from humans walking at a frequency of 2 ~ 3Hz charges the battery. The electric generator was simulated using MAXWELL, a commercial electromagnetic analysis program, to analyze the electric power generation. Finally a prototype of the mobile phone case for self-power generation was built based on the analysis and its performance was verified.

  • The purpose of this study is to grasp the opinion of Korean feminine seniors on the life support appliances for their healthy ageing: medication dispenser, video phone, activity monitor and sleep monitor. The focus group interviews, asking the usability of the appliances, were answered by each 6 feminine seniors of more than 65 years, residing in Corvallis of U.S.(group I), Cheongju(group II), and Ulsan(group III) of Korea. The results are as follows. (1) The medication dispenser proved to be very useful to all the respondents. All the seniors, who take more than one medicine a day, felt it helpful that the medication dispenser makes them to take medicines at fixed time. In addition, they hoped the medicine envelope to be developed for the dispenser use by the supply side. (2) The seniors showed interest in the manner the video phone works; to work by the voice, rather than by the finger. They expressed the hope of the video phone to display the communication contents, in consideration of their weakening hearing. (3) The seniors who live alone, especially, felt intimacy to the activity monitor, thinking as if some helpers were beside them. The fact that it can send emergency calls immediately when situations happen, gave the seniors emotional safety as a patron. (4) The sleep monitor, although essential to the serious cases without moving ability, was proved less necessary to the healthy seniors. They expressed the hope of this appliance to be evolved for the use with the mattress without bed.

  • Despite the ubiquity of telephone, the medium has received far less scholarly attention than it should deserve. This study begin with the purpose of fair appraisement of telephone in Korean social communication. To accomplish this purpose, the gratification obtained from telephone, the appropriateness of it as interpersonal communication medium and communication network through telephone were studied. The related raw data were collected from on-line survey process, and statistically analyzed. The result showed sociability, information, transaction, entertainment, emergency, and reassurance are gratifications obtained from telephone use. Younger persons tend to have more positive attitude to mobile phone as interpersonal communication medium. Particularly when the seniors are interpersonal communication partner and impending task is advice or request, younger persons tend to perceive mobile phone more appropriate than the elder persons do. And mobile phone deepens 'communication endogamy' of our society, especially in the youth. Thus, it is plausible to predict that mobile phone will be more important in social communication of our society when the youth become the mainstream of our society.
