The purpose of this study is to find out the use and inconvenience of informatization devices according to the disability of the elderly. A total 10,097 data from the elderly survey were used to analyze the differences in the possession and use of information devices, usage capabilities, and injustice according to disability. Descriptive analysis was conducted to find out general characteristics and disability-related characteristics. chi-square tests were conducted to find out the difference in informatization and communication device usage ability and information device usage inconvenience according to disability. The p-value was set at 0.001. As a result of the study, the elderly with disabilities in Korea had lower smartphones and tablet PCs than the non-disabled elderly. In terms of daily inconvenience, the elderly with disabilities often responded that they had no experience or did not know about the inconvenience of online reservations for trains/high-speed buses/intercity buses, ordering kiosks at restaurants, using ATMs, or reducing bank stores. Taken together, the ability of the elderly with disabilities in Korea to possess and use informatization devices is very low and they feel more inconvenience than the non-disabled elderly. It is necessary to improve the ability to possess and use informatization devices for the elderly with disabilities in the rapidly progressing aging of the disabled and the informatization of our society.

The purposes of this study are to investigate and analyze the level of information and the state of digital divide of the disabled by surveying the demand for information and communication assistive devices, and to provide basic data for plans on the development and utilization of information and communication assistive devices. In order to understand the actual condition and the state of digital divide of persons with disabilities, the differences of possession and accessibility of information technology devices, usage ability, and utilization were analyzed according to the disability profile by using the T-test. The results show that there are significant differences (T=-2.510*) of possession and accessibility of information technology devices with respect to the disability profile, and that the disabled have lower possession and accessibility of devices than the non-disabled. Result of this study's demand forecast shows that about 28% of total respondents are currently using information and communication assistive devices, and a majority (67%) of them answered that the use of assistive devices lend great help to their lives. The proportion of those who have been supported by the government or related organizations with information and communication assistive devices were 36% of the total respondents, and those satisfied with the performance of the devices were 46% of the total responses. Meanwhile, only 36% of total users answered that the operation and use of functions of the devices was easy and convenient, responding that the difficulty of operating assistive devices was the greatest inconvenience. Moreover, the general requests of respondents in regards to the devices were stabilization of device performance, miniaturization of size, simplification of buttons, and reduction of weight.

Recently, with a rapidly growing of the mobile content market, a variety of mobile-based applications are being launched. But mobile devices, compared to the average computer, take a lot of effort and time to get the final contents you want to use due to the restrictions such as screen size and input methods. To solve this inconvenience, a recommender system is required, which provides customized information that users prefer by filtering and forecasting the information.In this study, an tailored multi-information recommendation system utilizing a Personalized information recommendation system on smartphone is proposed. Filtering of information is to predict and recommend the information the individual would prefer to by using the user-based collaborative filtering. At this time, the degree of similarity used for the user-based collaborative filtering process is Euclidean distance method using the Pearson's correlation coefficient as weight value.As a real applying case to evaluate the performance of the recommender system, the scenarios showing the usefulness of recommendation service for the actual restaurant is shown. Through the comparison experiment the augmented reality based multi-recommendation services to the existing single recommendation service, the usefulness of the recommendation services in this study is verified.
