A Cheap Wearer Centric Location System
This project seeks to develop a location system to be used on wearable
computers. Cheap systems are usually based on a combination of RF and
Ultrasonics technology. THese systems have a couple of disadvantages.
First, using both RF and ultrasonics is twice as expensive as just using
Ultrasonics technology. Second, ultrasonics sensors usually have to be
put in the right place, the installer has to perform a calibration.
Third, simple ultrasonics technology is usually susceptible to
disturbances, for example, crisp packets or jingling keys.
Our approach is to use just ultrasonics. We want to design our system so
that it scales to any number of users, and we want the users to
calculate their location. Hence, we are constructing a solution where
the ultrasonic transmitters are laced in the building, and wheter the
users carry an ultrasonics receiver.
We are developing algorithms that allow the system to calibrate itself.
