ABSTRACT
Today, we see numerous computer terminals with touch screens. In particular, interactive kiosk terminals, which provide diverse services and allow users to obtain information easily, are increasing in popularity. The main advantages of kiosk terminals are as follows: for vendors, (a) reduction in space requirements (only kiosk terminals can supply a variety of information to a large number of users), and (b) reduction of personnel expenses (setting up kiosk terminals can avoid the use of window clerks.), and for suppliers, (a) users can receive services whenever required regardless of whether it is day or night, and (b) because users can use kiosk terminals without human assistance, strangers do not gain access to their personal information. To achieve these advantages, an individual user must use kiosk terminals spontaneously. The most critical problem of kiosk terminals is how to attract both potential and existing users. The popular usability evaluation methods for computer terminals assume previous use by users, and their principal objective is to evaluate usability and simplicity for existing users. Therefore, such evaluation techniques may not always be appropriate when evaluating the appeal for potential users.
