Every once in a while I get into a conversation with someone who thinks about sensors and says something like “Yes, I can see some uses for sensors but not in my business”.
The following video (from Shopperception) shows a use of a 3D video sensor to identify and track shopping behavior:
There are a number of companies doing projects like this. These same techniques could be applied to a variety of other industries that require personnel to actual do a tasks. Instead of just looking for intent to buy, it could be used for fraud detection or training.
For an addition to this particular demonstration it could be combined with other demand creation techniques to enhance sales. For example, when it appears that a person was thinking about buying something but changed their mind, offer them a coupon to shift the decision making process. Or in the training case, when they appear to be confused, proactively offer them some guidance and encouragement.
