The current invention provides an enhanced user experience for consumers by minimizing the number of click-throughs, and optimizing time spent by providing customizable, interactive visual multimedia collages of information created from several sources of information in scrollable snapshots. Moreoyer, the same experience is made available for the users on-the-go on their mobile device where they can access the same collages and interact with them in a manner meaningful to the modalities provided on the mobile device, such as phone calls, text messaging, and Wireless Application Protocol (WAP) browser viewing. On the desktop Internet, interested consumers will be referred from the image collage result sets to content provider or retailers' web sites. Each image has all the information: the advertisement from the seller, customer review, product rating, and seller rating composited together. In one embodiment, the consumer can click on any of the regions of the collage (e.g. customer surveys) to click through to the WAP site or Internet site housing the information. In other embodiments, the consumer can just browse the information, consummate a buy transaction on-line: get it shipped or pick it up himself, place a bid for a used product, and/or call a number for more information. Through the system's analytics engine, the invention provides to the retailers competitive location-based information, consumer behavior data for advertising, and location based product demand. The consumer can save any of the interactive images and forward to others. For enterprises, retailers, and individuals interested in selling new/used products, they can create advertisements for their products using the Internet web based information collage authoring tool.
