How Context Awareness InsighT Makes LBS Meaningful! i n recent times, there has been a Location based services (LBS) may be the rage around lot of talk about location-based the world, but have not made their presence felt in India. services (LBS) – applications that Could context awareness hold the key to their success? integrate geographic location while delivering relevant information. Interestingly, LBS as a concept is not new. It is in fact almost a decade old and has been in use in the enterprise domain for years. However, it has not made its presence felt in the consumer sector for some rather interesting reasons. One cannot have a tasty dish without the right ingredients. Well, the same applies to technologies. . Some of the ingredients considered necessary to make LBS relevant to a broader base of consumers were the existence of standards, efficient computing power, friendly yet-powerful human-computer interfaces, higher penetration of feature- rich smartphones, GPS (global positioning system) devices, a geographical database for locations, and a rich collection of points of interests. While most of the ingredients seem to have reached the threshold to enable the use of LBS in developed countries, developing economies like India are still struggling in this regard. Perhaps India’s dense population and middle class dominance doesn’t make investment intensive ingredients like GPS devices, smartphones, PNDs (portable navigation devices), etc, a common need. Thus, delivering location-based services has been a greater challenge in this part of the world and requires different strategies from those that succeeded in the west. 57 i.t.­­­­­­­­­­­­­­­­­­­­­­­­|­­­­­­­­­­­­­­­­­­­­­­­­www.itmagz.com­­­­­­­­­­­­­­­­­­­­­­­­|­­­­­­­­­­­­­­­­­­­­­­­­February 2009­­­­­­­­­­­­­­­­­­­­­­­­|­­­­­­­­ ­­­­­­­­

Similarly, a famous dry-fruit shop in the area may like to notify me that it is offering cashew nuts at a discount. Since most people are in a frame of mind to shop in that area, chances are that they may go there to check the prices and end up making a purchase. Since it is winter, chances are that most shoppers are looking for woollen clothes on discount in the area and, 58 | February 2009­­­­­­­­­­­­­­­­­­­­­­­­|­­­­­­­­­­­­­­­­­­­­­­­­www.itmagz.com­­­­­­­­­­­­­­­­­­­­­­­­|­­­­­­­­­­­­­­­­­­­­­­­­i.t.­­­­­­­­
