Designs for Effective Implementation of Trust Assurances in Internet Stores

Improving customer trust in an Internet store is an important goal in B2C electronic commerce because it leads to outcomes important for the success of an Internet store, such as reduced customer risk perceptions in transacting with the store and increased willingness to buy from the store. One of the critical success factors for Internet stores is to convince customers of the store's trustworthiness.

Multimedia-Based Interactive Advising Technology For Online Consumer Decision Support

Multimedia technologies (such as Flash and QuickTime) have been widely used in online product presentation and promotion to portray products in a dynamic way. The continuous visual stimuli and associated sound effects provide vivid and interesting product presentations; hence, they engage online customers in examining products. Meanwhile, recent research has indicated that online shoppers want detailed and relevant product information and explanations [2]. A promising approach is to embed rich product information and explanations into multimedia-enhanced product demonstrations. This approach is called Multimedia-based Product Annotation (MPA), a product presentation in which customers can retrieve embedded product information in a multimedia context.

An experimental program investigating color-enhanced and graphical information presentation: an integration of the findings

A series of three laboratory experiments were conducted to assess the influence of graphical and color-enhanced information presentation modes on decision quality, decision making time, use of information, and user perceptions. The experimental design allowed for the unconfounded study of line graphs and color using a variety of information presentation designs for the same decision making task. Based on the findings of these studies, propositions about the impact of graphics and color on individual decision makers are presented. The influence of presentation mode on human performance and the perceived value of information is related to how well it supports the solution approach to a particular task. The benefits of graphics are limited to reducing decision making time but only when the graphical report has been designed to directly assist in solving the task. Multicolor reports aid in decision making, but only in specific circumstances, that is, their benefits are not pervasive. It appears that color is more advantageous when associated with graphical reports, for certain decision maker types, during learning periods, and in time constrained environments.

A critque of the stage hypothesis: theory and empirical evidence

The stage hypothesis on the assimilation of computing technology provides one of the most popular models for describing and managing the growth of administrative information systems. Despite little formal evidence of its reliability or robustness, it has achieved a high level of acceptance among practitioners. We describe and summarize the findings of seven empirical studies conducted during the past six years that tested various hypotheses derived from this model. The accumulation of evidence from these studies casts considerable doubt on the validity of the stage hypothesis as an explanatory structure for the growth of computing in organizations. 3~

An experimental study of the human/computer interface

An exploratory study was conducted to analyze whether interface and user characteristics affect decision effectiveness and subject behavior in an interactive human/computer problem-solving environment. The dependent variables were performance and the use of the systems options. Two of the independent variables examined, experience and cognitive style, were user characteristics; the other three, dialogue, command, and default types, were interface characteristics. Results indicate that both user and interface characteristics influence the use of the system options and the request for information in the problem-solving task.
