A Study On Interaction Design Of Touch Interface Of Kiosks

With the development of technology and services, kiosks (or self-service terminals) were extensively used in finance, transportation and entertainment, etc. The service mode is gradually changing from "human-human" at the counter to "human-machine" at kiosks. Touch interface is the key I/O medium of kiosks and the usability of it directly affects the satisfaction of users. The users of kiosks are variable and some of them are lack of computer experiences, so the unintelligible interface, the complex interaction will frustrate their confidence to use the self-service systems. The aim of this paper is to improve the usability and explorer the proper interaction patterns of touch interface of kiosks.This paper discussed interaction design of self-service systems from research, task analysis, information architecture, interface layout, interaction patterns and prototype testing, found out users'needs and the design goal from the research of "human-machine-environment" system, got the task and decision-making flow from studying the counter service, set the interface sequences based on the decision-making flow, and then discussed the method to organize the information and items in order to make users easily find the information what they want. At last, the paper discussed the method to arrange the interface layout and group the interface elements.Due to the difference of input mode, the interaction patterns and behaviors of touch interface are much different from the Windows system. This paper tried to explorer the interaction patterns and behaviors which suit to the touch interface of kiosks, like menus, buttons, popup windows, data input, selection and feedback, and then proposed some interaction design principles of self-service systems, in order to make the system easy to understand and easy to use.Prototyping is an important and good method in interaction design. Design ideas were examined and showed through "paper prototype" and design solutions were tested through "interactive prototype", so we can get the usability problems at the early stage from this way. The paper discussed the method to construct paper prototype and interactive prototype. At last, the paper took the interactive prototype "Campus Guide System of Shandong University" as example to conduct usability test and made some analysis of the test results.
