Empirical analysis of consumer reaction to the virtual reality shopping mall

The Internet shopping mall has received wide attention from researchers and practitioners due to the fact that it is one of the most killing applications customers can find on the Internet. Though numerous studies have been performed on various issues of the Internet shopping mall, some research issues relating to the user interface of VR (virtual reality) shopping malls still await further empirical investigation. The objective of this study is to investigate whether the user interface of the VR shopping mall positively affects customer satisfaction in comparison with the ordinary shopping mall. For this purpose, we developed a prototype of the VR shopping mall for which the user interface consists of both 3D graphics and an avatar, using it as an experimental medium. 102 valid questionnaires were gathered from active student users of the ordinary shopping mall, and two research hypotheses were then tested to prove whether the three explanatory variables such as convenience, enjoyment, quality assurance improve in the VR shopping mall, and whether customer satisfaction is also significantly enhanced in the VR shopping mall in comparison with the ordinary shopping mall. Additionally, we conducted the PLS (partial least square) analysis to test whether the customer satisfaction is explained significantly by the three explanatory variables or not.     

vCOM: Electronic commerce in a collaborative virtual world

Existing e-commerce applications on the web provide the users a relatively simple, browser-based interface to access available products. Customers are not provided with the same shopping experience as they would in an actual store or mall. This experience, however, can be achieved by the creation of a virtual shopping mall environment, simulating most of the actual shopping user interactions. The virtual mall brings together the services and products of various vendors. Users can navigate through the virtual shopping malls, adding items of interest into a virtual shopping cart, and perform searches assisted by ‘intelligent agents’. A Collaborative Virtual Environment (CVE) can realize a sophisticated virtual shopping application. In such a CVE, a large number of potential users may interact with each other. In this paper, vCOM, a VRML and Java3D-based prototype is presented, which permits users to navigate around virtual e-commerce worlds and perform collaborative shopping and intelligent searches with the assistance of software agents, in order to find the products and services of interest to them. They can then negotiate with sales agents to bargain for the best possible price and then make a secure buying transaction. The virtual mall prototype also allows the user to communicate with an ‘intelligent shopping assistant’ using simple voice commands. This assistant interacts with the shopper using voice synthesis and helps him/her use the interface to efficiently navigate in the mall. Real-time interactions between the entities in this shared environment are implemented over the High Level Architecture (HLA), an IEEE standard for distributed simulations and modeling. The paper focuses on user interface design, collaborative e-commerce through HLA and multi-agent architecture.     

Finding a person with a wearable acceleration sensor using a 3D position tracking system in daily environments

Person identification with accurate position information is essential for providing location-based services in real environments, such as a shopping mall. For this purpose, we propose a method that integrates 3D position information from environmental depth sensors and acceleration data from wearable devices to anonymously gather the trajectories of people who have wearable devices as well as others. Our proposed method identifies a person who has a wearable device by comparing two time series of acceleration data from device and position information. To do this, we extracted the behaviours of each axis using the changes of each bit of acceleration data at certain time periods. We evaluated our method with data collected at a shopping mall and a children’s playroom to investigate its effectiveness and robustness in different environments. Our evaluation results showed that it achieved an average identification of 85%, which is better than several alternative methods.

A web DSS approach to building an intelligent internet shopping mall by integrating virtual reality and avatar

This paper is concerned with designing and implementing the Internet shopping mall by using a virtual reality-driven avatar and web decision support system (Web DSS). Traditionally, the Internet shopping mall has been designed based on the combination of several hyperlinks, images, and texts. However, this sort of approach results in a lower performance because possible customers cannot make accurate shopping decisions. To overcome these kinds of pitfalls facing the current Internet shopping malls, we propose using a combination of virtual reality and Web DSS. The main virtues of our proposed approach to designing the Internet shopping mall are as follows: First, the virtual reality technique is emerging as one of the alternatives that guarantee a sense of reality for the customers' part and facilitating the complex process of shopping decision makings. Especially, the avatar, which is an artificially designed man working on the Internet, can make the Internet shopping-related decision making processes easier. Second, the Web DSS approach can provide an effective decision support mechanism for customers. Especially, we design a set of intelligent agents for the proposed Web DSS. Experimental results with an illustrative example showed that our proposed approach can yield a new Internet shopping mall paradigm with which customers can benefit from a high level of decision support functions.

The impact of the online and offline features on the user acceptance of Internet shopping malls

Internet shopping mall has the dual nature of Web-based application system and traditional shopping mall. This paper explores online and offline features of Internet shopping malls and their relationships with the acceptance behaviors of customers. The results from a Web survey of 932 users show that the technology acceptance model (TAM) is valid in predicting the acceptance of the Internet shopping malls and that online and offline features have positive effects on the user acceptance. Both online and offline features have greater effects on the usefulness, attitude, and intention to use than either online or offline features separately. This study provides a domain-specific, integrative approach in evaluating the quality and antecedents of user acceptance for Internet shopping malls.
