|Summary||Despite many failures, electronic home shopping with broadband interactive television and/or multi-media PCs is still believed to have attractive potential by many retailers, technology and communications firms around the world. Previous studies on electronic home shopping suggest that good user interface with appropriate format of information display is key to the acceptance of the technology by potential users. This paper reports an empirical study which looked at different formats of product information display in an electronic supermarket shopping environment. Four prototypes with different combinations of text and pictures display were developed and evaluated in an experimental setting. The results suggest that pictures are more efficient to help the user complete the shopping task although having more pictures does not necessarily lead to correct purchase. Moreover, customers may have a different shopping behavior in the electronic environment from the traditional one in terms of frequency, day and time of the shopping, product items bought and factors for satisfied shopping.|
