Design of Digital Reading Interface Considering User Experience

Abstract

The issue of diversity of public users’ cognitive competence is always one big challenge in the interactive design field of digital reading material interface. The author analyzes and models the interactive activities of digital reading material interface based on the Distributed Cognition Theory, confirms the relation between the interactive activities and information in the process of human-computer interaction, and, on the basis, raises the interactive design method of digital reading material interface based on users’ cognitive competence. When adopting this method, the designers shall firstly conduct user survey and identity the user groups in need of care, then analyze the cognitive competence, establish the users’ effort model, and describe users’ interactive behaviors, confirm the basic interactive framework, and establish the interactive design matrix by using the universal usable design method, and raise the interactive design scheme. We take the digital reader terminal as the case, adopts the method to formulate the design scheme, and verify the validity of the design method by comparing the design scheme with the traditional method. The interactive design method can help designers develop easily understandable and easy-to-use digital reading material interface, reduce users’ effort models and better satisfy digital reading material users’ needs of cognitive diversity. Introduction With the popularization of the digital reading materials in every service field, and it’s user groups is increasingly widespread; however, the public users have different educational degrees and computer operation experiences. The traditional interactive design method of digital reading material interface are mainly oriented towards the user groups with rich operation experiences in computer products and are not sufficient to meet the public users’ needs of cognitive diversity. The paper considers the self-service registration service terminal interface of digital reading materials as the case of interactive design, based on the research of the interactive design modes of digital reading material interface, introduces users’ cognition-based interactive design method and design processes of digital reading material interfaces, and presents the design scheme to realize the aim of decreasing users’ effort models and meeting their needs of cognitive diversity. The Establishment of the Interface Interactive Models Simplifying the interface interactive processes and providing the interface information easily understood by the public users are two main approaches to reducing users’ effort models occurred in the human-computer interaction. Researching the interactive design of digital reading material interface based on Distributed Cognition Theory and Universal Usability Design Method can provide the necessary support for the realization of the aforesaid approaches. Applying the resource modes of the Distributed Cognition Theory into the development process of the digital reading material interface can simplify the interface interactive processes, distribute the cognitive resources to the system, and provide reasonable supplies to help users understand the interface information to reduce users’ effort models at the most extent and let the user groups with different cognitive competences be capable of completing the basic interactive tasks. The interface interactive models and design method of digital reading materials based on this can help designers make reasonable decisions of the interface information distribution. 5th International Conference on Information Engineering for Mechanics and Materials (ICIMM 2015) © 2015. The authors Published by Atlantis Press 1116 Interface Information Structure Unlike the traditional human-computer interface, the digital reading material interface is mainly characterized by single-window full-screen operation. The users only can complete the specific operation tasks in accordance with the fixed and single interactive processes, which presents higher requirements for the system’s procedures. Meanwhile, due to the public use environments of digital reading materials, users are influenced greatly by the contextual factors in the interactive process, so it is feasible to introduce the processes and contextual factors into the resource models and establish the corresponding information interactive strategies and the interface interactive models oriented towards digital reading materials to describe the relations between interactive movements and information resources in order to help the designers analyze whether the proposed design scheme can reduce users’ memory selection load and realize the aim of reducing users’ effort models. The information structure of the digital reading material interface interactive models is shown in figure1. The processes in Table I is defined as the set of operation sequences. The description of the processes can conduct timely tracking to the targets. Contexts are defined as the status or variables related to users’ interactive activities in the process of human-computer interaction.
