Indoor Location Based VOD Service Using Smart Phone Sensors

A smart phone is the best device on which a location based VOD service (ILBVS) runs, because a smart phone has PC level computing power and storage capacity, and it is a personal belonging that the owner always carries. Thus, this paper proposes an efficient way of implementing an ILBVS as a smart phone app. ILBVS cannot be realized unless the system can estimate the user's location. We use a dead-reckoning indoor positioning method that determines user's location using smart phone sensors. Another necessary ingredient of ILBVS is a map that is the most important element of the LBS's user interface. We obtain the floor map from the floor map repository. The most important contribution made by this paper is the method of guessing what the user is most interested in at the current moment. With this method, we implement an example ILBVS.
