personal sensing devices are becoming more commonplace ineveryday life. Unfortunately, radio transmissions from thesedevices can create unexpected privacy concerns if not carefullydesigned. We demonstrate these issues with a widely-availablecommercial product, the Nike+iPod Sport Kit, which contains asensor that users put in one of their shoes and a receiver thatusers attach to their iPod Nanos. Students and researchers from theUniversity of Washington found out that the transmitter in asneaker can be read up to 60 feet away. Through the use of aprototype surveillance system, the researchers could track someonewearing Nike+iPod sensors, plot their location on aGoogleMaps-based website and emai and text-messaging real-timesurveillance data to anyone.

You are interested in deploying sensor technology in the cafe tohelp revamp operations. How would you address the following:

Many cafes are putting sensors on the bottom of cups to helpalert the wait staff that a customer needs a refill. Would youintroduce this technology to the cafe? If so, are there anyconcerns with using this type of technology?

What other types of sensors could you deploy throughout the cafeto help operations? What concerns would you have regarding thesesensors?

Are there any current laws that you would need to be aware ofwhen deploying wireless technology? If so, what types ofliabilities for potential lawsuits should you be aware of toprotect the cafe? If not, what types of laws should be created tohelp protect customers, employees, and the cafe?
