Docomo's Peripheral Display Coordination system is location aware
Peripheral Display Coordination is a new service concept being explored by NTT Docomo. The idea is to use a home TV or digital signage to display relevant, context sensitive content to users via their smartphone.
"Even if people have information about special deals, such as a coupon, they may forget about it when they're in the store. But with this system, if there's a compatible display nearby, you could be notified that "This coupon is available, would you like to use it?", even if your smartphone is in your pocket."
"In a private context, people often go home and leave their smartphone unattended in their bag. At times like that, they could be notified on a TV or PC that "You've got lots of missed calls," or "You've still got unread mail"."
"One feature of this technology is, it even detects where the display is. Thinking about similar services, many cover a certain range, using Bluetooth only or Wi-Fi only. But with this system, the display can be identified by using Bluetooth and Wi-Fi together."
"Identifying the display also makes it possible to identify whether a space is public or private. If a display is public, the system can be set not to show information like unread mail or missed calls. Also, here, an avatar is displayed with the information, and this also serves as a marker, showing who the information is for. So anonymity can also be provided, because you can recognize if your marker appears."
