In the real estate business, the key catchphrase is “Location, location, location”. Knowing the location of users can be just as advantageous for other commercial applications. Outdoors, we may use GPS, itself already a lucrative market. But indoors, GPS is unhelpful due to signal unavailability. The challenge is to develop a technology that pin-points users’ indoor location which can translate into a wide variety of location-based services and high commercial potential. At HKUST, we have been developing indoor position technologies that locate potential users with high accuracy. In this talk, the speaker will walk you through the market opportunities and technologies of indoor location. Together they promise to be the “next big thing”.
