Microsoft has developed technology that, using a small camera that's placed within a digital sign, can determine whether you're a man or woman and deliver an appropriate ad. The system has the most practical application in places like malls where large video screens could be displayed. This is just part of Microsoft's plan not to be counted out in terms of advertising revenue.

I have the same problem with this I have with most such systems. At my local mall, even on a slow day, there are probably 10 people in any given area at a time. So who is the camera going to select? The one it can get the best read on? That seems not to be the best solution. And the problem only gets worse during higher-traffic times.
