relating to marketing purposes. This involves monitoring how many people there are in the street next to that certain shop as well as the use of a heat map generator. The heat map generator will basically allow the manager or staff at a store to observe how exactly people are moving. It will also allow staff workers to see what things in the store are attracting the attention of the customers the most. Controversy and privacy concerns Although this sort of technology does seem helpful and practical, certain issues and concerns arise among everyday people who are doubtful about how such computers are going to be used. Some people debate on the issue of security and privacy with such computer technologies. With this new technology comes a bit of concern with the public. Therefore, researchers and scientists have to take into perspective that such computer devices that can read body language have to give people a warning of that kind of a capability. So when building and putting into effect this type of computer, so to say as a means of security, there has to be concern over whether or not to take into consideration if this kind of computer technology would be accepted by the general public. That includes people who are possibly going to be observed and monitored by a kind of computer that analyzes their body movements and gestures when they are doing something as simple as shopping at a mall or traveling through airports.
