현대 사회에서 사람과 사람이 아닌 기계와 사람 간의 거래가 대중화 되고 있다. 무인 거래 시스템(이하 키오스크) 사용이 지속적으로 증가하는 이유는 높은 인건비의 절감, 편리성, 시간 단축으로 볼 수 있다. 반면, 키오스크 사용은 다음과 같은 단점이 있다. 메뉴 선택에 있어서 주위 사람들에 의해 심리적 불안감이 생겨 충분한 시간을 가지지 못하고 메뉴를 선택하여 원치 않은 주문이 발생 할 수 있는 것이다. 이 논문에서는 키오스크로 메뉴 선택에 있어서 심리적 불안을 가지는 사람 및 키오스크 사용에 불편함을 가진 사람들이 효율적으로 접근할 수 있는 시스템을 제안한다. 이를 통해 해당 매장에서는 다른 고객들의 눈치를 보지 않고 충분한 시간적 여유를 가지고 메뉴를 선택하여 편리하게 사용 할 수 있는 장점이 있다.

최근 키오스크 사용 비중이 커짐으로써 그에 따른 사용자들의 개인 정보에 대한 보안 위협이 증가하였다. 호텔과 같은 숙박업소에서 이용하는 키오스크의 경우 체크인을 하기 위해 사용자들의 개인정보를 입력하는 것은 물론 숙박하는 호실의 정보도 가지고 있다. 이 경우 정보 유출 시 개인 정보 유출 이외의 다른 범죄가 발생할 수 있다. 이와 같은 키오스크 보안의 한계점을 보완하기 위해 본 논문에서는 Tendermint 기반의 블록체인을 이용하여 기존 일방향적인 결제 시스템을 지닌 기존 키오스크 체크인 시스템의 단점을 보완하고 키오스크 체크인의 보안성 및 신뢰성을 강화하는 방법을 제안한다.

Kiosks are gaining popularity as an essential tool that offers unmanned services and payment systems, and their use is rapidly increasing in the service industry. However, the use of kiosks can be challenging for the elderly who are not accustomed to digital technology and touchscreens. Consequently, this study develops an educational program that utilizes metaverse technology to enhance the digital skills and kiosk service accessibility of older adults. This research has created an educational system that allows the elderly to learn digital skills and kiosk access through play.

Hospital Kiosk is a useful means to decrease human resources and to extend service hour to non-working hour for the stance of hospital and to obtain useful services without time loss in waiting in lines for the stance of user. However, various kinds of information kiosks are respectively installed with independent functions, and they have bad usability due to complexity in manipulate and unclear information architecture. In this paper, we tried to analyze usability and respective functions of each kiosk and aimed to suggest alternative information architecture for the integrated hospital kiosk. We categorized users as patient, guardian and visitor and we conducted usability test and in-depth interview with each group of users. based on result analysis from the research, we could suggest proper information architecture for the integrated user centered hospital kiosk. The new information architecture for the integrated hospital kiosk has better accessibility to the menus which reflects users's preemptive needs and it includes more specific information that can support user tasks.

The purpose of this study is to identify belief variables of kiosk that affect satisfaction and recommendation intention by applying vertically extended technology acceptance model (TAM). As results of this study are as follows. Firstly, the perceived usefulness and perceived ease of use have an impact on satisfaction statistically. Second, the perceived usefulness and perceived enjoyment of the kiosk showed a positive(+) influence on the recommendation intention. Third, users who satisfied with kiosk service have strong recommendation intention to their friends, family and colleagues so on. These findings support that the usefulness and usability of the new information technology identified in the existing technology acceptance model is a key variable affecting user reactions (satisfaction and recommendation intention). Additionally, the perceived enjoyment is an important factor as new belief variable for explaining the formation of recommendation intention through satisfaction of kiosk service. The results of this study contribute to verifying the empirical model between the belief variables(perceived usefulness, perceived ease of use, perceived enjoyment) and the recommendation intention.

최근 키오스크의 사용률이 증가함에 따라 키오스크 사용의 어려움을 겪는 정보 취약계층이 존재한다. 키오스크 사용시 메뉴 선택을 키오스크 앞에서 하며, 절차 또한 복잡하다. 또한 키오스크의 높이가 고정되어 있어 휠체어를 타신분, 어린이 등 고정된 높이에 맞지 않는 사람은 사용이 어렵다. 이를 해결하기 위해 맞춤형 추천과 자동 높낮이 조절 키오스트에 대한 연구가 활발하다. 본 논문에서는 사용자 맞춤형 키오스크를 위한 얼굴 분석 기법의 성능 연구 결과를 제시하고 있다. 가장 대표적인 얼굴 분석 알고리즘들로 알려진 MS Azure 얼굴 분석 기법과 네이버 클로바 얼굴 인식 기법에 대한 비교 실험 결과 성별 인식의 경우 MS Azure 기법이 조금 우수했고 나이 분류의 경우에는 비슷한 성능을 보이는 것을 확인할 수 있었다.

Although the use of kiosks is increasing recently, the digital divide for the elderly who uses them is not decreasing. We live in an environment where the use of kiosks is becoming a necessity rather than an option. In such an environment, the digital alienation of the elderly is becoming a problem directly related to the quality of life. Even if a kiosk is developed considering the elderly, the verification of its effectiveness is ambiguous, or in most cases, it depends on the designer's experiential ability rather than the consideration of usability. In this study, the usability of the kiosk was analyzed for the development of kiosk contents for the elderly. The metrics were defined as availability, usefulness, efficiency, attractiveness, and visibility. And the measurement method of the measurement index was developed, and the usability of the kiosk for the elderly was confirmed by performing usability evaluation. This is a method to verify whether the kiosk in the development process can support the elderly or whether the improved kiosk actually increases the usability of the elderly. As a result, it is expected to contribute to improving the accessibility of the kiosk.

Kiosks are widely used in drive-thru systems in parking lots or on the highway to provide various services to drivers. However, the driver must stop at an exact location to access the kiosk, since its panel is fixed. In order to improve the kiosk accessibility, in this study we developed a manipulator that can adjust the position of the kiosk panel. The number of active joints was minimized to lower the cost, whereas a parallelogram mechanism and passive joints were adopted to increase its convenience for the users. Furthermore, a safety mechanism using springs and a cam was designed to ensure the safety of the user in the case of an emergency. The performance of the position controller and the safety mechanism were verified through various tests. In addition, the proposed collision reaction strategy improved the safety performance of the kiosk system.

In this paper, we studied the voice recognition system kiosk for convenience, thinking that the kiosk widely used in modern society should compensate for the inconvenience of using by the visually impaired. Using ultrasonic sensor and PIR(Passive Infrared), it recognizes the visually impaired within the range of 80cm-40cm, introduces the kiosk through the MP3 module and induces them to come closer. Also, when the visually impaired within 40cm is recognized, the product description and order are guided through the MP3 module. A recording-based data voice recognition system and a kiosk that outputs desired items through servo motors were studied. A kiosk for the convenience of the visually impaired was manufactured through operation and optimization experiments of PIR, ultrasonic, voice recognition, and shock sensor for the manufactured voice recognition kiosk. Finally, it was confirmed that security can be strengthened by using shock sensors and emergency bells to enhance security.

The purpose of this study is to increase the experience of using kiosks for elderly in the non-face-to-face age. Through prior research and literature research, feature of kiosks and characteristic of elderly user were identified, and improvement were suggested through Ethnography and in-depth interviews. The research method was conducted for 13 days from April 4 to 16, 2021 for 11 senior citizens in their 60s or older living in Incheon. A total of 11 people were interviewed by adding 3 people who had experience in using kiosks. As a result of the experiment, interfaces and psychological factors were derived with paint points in the process of use of the elderly, and the five improvement plan was proposed by combining them. This study is expected to serve as a source for research on the experience of elderly kiosk users or kiosk interface design.
