It seems like most of us are short on time these days, despite having a house full of gadgets to take care of many of our everyday tasks. That smart phone might help you keep track of appointments at first, but it can only do so much to actually make your life easier. This conceptual product is described as a “life support” device, meant to take care of remembering all of those little things you might otherwise space off and forget.

The Mercator is part personal data assistant, part health monitor, part GPS, part shopping assistant, and all must-have cutting-edge technology. New nanotechnology and a tiny AMD processor chip make this functional but stylish piece come together in a way that makes us want one right now.

Far from being just a wrist-mounted PDA, the Mercator – designed by Chinese UI designer Kingyo – actually uses holographic imaging to display the information you need to keep your life in order. Appointment details, information about your current vital signs, and even your grocery shopping list pop right up in front of you to keep you on track no matter where you are.

The device can tell what type of store you’re shopping in (presumably with some related piece of infrastructure that’s present in the store) and presents you with recommendations and reminders based on your buying patterns and preferences.

Of course, the conceptual device includes rechargeable batteries so that you can simply charge it at night along with your other daily-use electronics. The device, which will no doubt become a permanent part of the owner’s daily accessories, can be customized appearance-wise to suit the wearer’s style. While the Mercator might be a few years from realization, the technology used in the concept’s rendering seems almost close enough to touch.
