Figure 1.1 shows the detailed contents of these essential factors of m-commerce acceptance. Figure 1.1 Source: Essential factors of m-commerce acceptance in the previous studies Choi et al., (2008) The above figure 1.1 illustrates the essential factors of m-commerce acceptance such as “transaction process” and “customization” which lead customer satisfaction when connecting an m-commerce site. However it has unique aspects of “content reliability”, “availability”, and “perceived price level of mobile Internet which build customer’s intention to use m-commerce site. 12 1.2.4 M-Commerce Limitations Although, m-commerce offers a variety of features and tremendous flexibility, however there are certain limitation associated with m-commerce, some of these limitations are identified by Matskin and Tveit (2001); Ralph and Aghvami (2001); and Siau et al. (2001). The current limitations associated to WAP m-commerce can be summarized as following: Short access life due to low power voltage and the small battery size Limited process power due to low power computer processing chips Higher risk of storage and transaction errors. Restricted view of large or multiple page images due to very small screen displays Less "surfability", i.e. limited navigation facilities because of restricted cursor and button zcontrol. Restricted graphics and colors, as sometimes any color and images could not supported. Sometimes access requires when new hardware if using a mobile phone and new software and information is being accessed through a PDA. No usage of the basic Internet TCP standards that prevents information exchanges with the majority of Internet providers. The present WAP specification is restricted to 56-bit encryption on many mobile phones, which is a far lower from the 128-bit encryption used for secure web transactions. 1.3 Aim of the study The main purpose of our study is to evaluate the usability principles of WAP services. Furthermore it does with the intention of being able to identify key factors that will influence the future success and development of WAP enabled services. 13 1.4 Research Questions Based on our problem discussion, we have formulated two research questions which are as follows: RQ 1. Does the design of WAP services contain major usability flaws? RQ 2. How the m-commerce interface design can be made user-friendly? 1.5 Delimitations of the study The time available for this study was limited and aspects of the topic were many, an attempt to narrow down our research was made. The study will focus only the usability flaws in WAP services and how the interface design can be made user friendly. 1.6 Outline of the Thesis This thesis is divided into seven chapters, as shows in figure 1.3 namely the Introduction and Background, Literature Review, Methodology, Data Presentation, Data Analysis, Conclusion and Recommendations. Chapter one gives an introduction and background to the research topic, problem area and research questions. Second chapter presents the literature review, the third chapter presents conceptual model and emerged frame of work based on earlier studies. It also shows the choice of literature to answer our research questions. Chapter four will presents the choice of research methods to carryout our research. In chapter five we will presents the collected data and in chapter six we will analysis data in contrast with literature review and finally we will make conclusion and recommendation of our research. 14 Introduction and Background Literature Review Conceptual Framework Methodology Data Presentation Data Analysis Conclusion and Recommendation Figure 1.2 Disposition of Thesis 15 CHAPTER 2. LITERATURE REVIEW This chapter contains the relevant studies already done on usability factors of WAP enabled Services. Initially we will bring up theories to support research problem and start with a broader view of HCI concept and its objectives, followed by usability, system acceptability, usability attributes and principles to support usability design. Finally, we will narrow down our research problem and comes up by general principles to support WAP usability. This chapter will makes a ground for our conceptual frame of work. 2.1 The User-Centered Interface Design There is no contradiction that many computing systems have been designed with very poor interfaces. It is important to note that the increased functionality should not be used as an excuse for poor interface design. It is possible to design good interfaces in which different system features can be controlled effectively that can provide useful and quick response. These successful systems can be made from a good knowledge of HCI (Human Computer Interaction) design principles. The essential principles of usercentered design are to put the users and user issues central in the design process, to carry out early testing and evaluation with users to make design succ...
