From PARC, the mobile phone as tour guide
Elinor Mills, CNET News.com, September 28, 2007
Excerpts from the article:
...Today, most people wandering foreign streets in search of something ask someone passing by. If you have a particular store in mind and your mobile phone is Web data-enabled, you can use the Internet and an online map. But if you don't know exactly what you want, there's no real guide.
Palo Alto Research Center, or PARC--the Xerox subsidiary that was the birthplace of the computer mouse, the graphical user interface and Ethernet--has developed a mobile application that offers up information that would be useful to a wanderer--things like shops, restaurants and event listings based on your location (via the GPS device in the phone) and the time of day, as well as your preferences and past behavior.
The leisure city guide system will be commercialized by Dai Nippon Printing (DNP) in Japan, with trials scheduled to start in the spring and general availability in that country in spring 2009...
...The more you interact with it--showing preference for things and rating them--the more it learns about your personal tastes, and its suggestions reflect that. It uses collaborative filtering to recommend things that others with similar tastes like and allows people to input their own ratings and reviews.
