This paper investigates how interface design can help to overcome the proclaimed ‘lack of trust’ in e-commerce sites. Based on existing social science knowledge on trust, and our own exploratory study using Grounded Theory methods, we developed a model of consumer decision making in online shopping. Due to the separation in space and time when engaging in e-commerce, there is an increased need for trust, rather than the oft-proclaimed lack of trust. Based on this model we then review design guidelines through empirical tests. We focus on approaches that aim to increase trust by increasing the social presence of an interface. We identified cues in the user interface that help to build trust to some extent (trustbuilders), and some cues that have a great potential for destroying trust (trustbusters).

Abstract: E - commerce still suffers from consumers" lack of trust Most e - commerce researchers focus on building trust through cues that appeal to rational decision - making These cues are usually implemented as text (e g privacy policies) In print advertising, affective attitudes and trust are commonly built by using photographs of people On the web, however, users as well as interface design experts believe that photos impair task performance by attracting visual attention In this study we compared online - shoppers' gaze patterns on pages with a photo of a person to pages with a text box of the same size Our data does not support the claim that photographs decrease task performance In fact, users spend more time looking at the text box We found that the photograph attracts more attention than the text box on a first time view of a particular page However, participants quickly learn the structure of a page and ignore the photo on subsequent pages We outline further research, incorporating physiological measurements to infer user cost and affective responses

Consider shopping in the real world: When a customer enters a shop for the first time, she sees the interior, goods and the sales staff. Visual cues allow her to evaluate the shop’s professionalism and competence. Furthermore, interaction with service staff will trigger immediate affective responses that impact her trust. However, she may not conduct any risk evaluation at all, because shopping is a habit she does not perceive as risky.
