:: Indoor Wireless Positioning ::
I have twice worked on this issue. Originally for MetroWalker in Hong Kong, I included consideration of indoor positioning in a research report for location services. I was also asked by a UK company to investigate the use of indoor wireless in shopping malls for virtual shopping guides and shelf space etc.
A friend at Symbol had mentioned to me the success of their self-scan system for supermarket shopping. The scanning devices are connected using WiFi. An obvious extension of this service is to provide information on the scanning terminal via a built-in display. The information could be tailored according to which aisle the shopper is in. All that is needed is the ability to determine location.
I was glad to find out that one company, at least, called Ekahau, has come up with a location solution for indoor WiFi coverage. I am planning to investigate what other methods are possible. Please let me know if you have come across any.
