Equipped with five pressure sensors and two wireless
motes, the GaitCoach is a product to help correct and monitor walking
gait. In the intended design, there are two basic components to
the GaitCoach - an insole and a small feedback unit. The insole
is to be worn as an insert in the shoe, and comes in different sizes
to accommodate different foot sizes. It has five pressure sensors
located on various parts of the sole, which all connect to a mote
attach at the top of the foot. This mote then sends a real-time
wireless signal to the second mote, located in the wristwatch-sized
feedback unit. This unit comes with a nylon band with which you
can strap onto your wrist and wear like a watch. To account for
the various sensory limitations of different users, you can choose
from visual, tactile, or both feedback methods. Using pre configured
settings, the mote in the feedback unit calculates the information
sent by the mote located on the foot. The feedback component will
then vibrate if pressure is being overapplied or applied incorrectly;
visually, the LED will switch from green to red. In addition to
providing real-time results, the GaitCoach interfaces with laptops
to give progress reports over time. Our current prototype implements
this second feature. The mote on the foot
interfaces with the base station and the force sensor data is sent
into a file which then can be used to track the patient’s
progress. Powered by vibrations and movement, the GaitCoach is your
personal coach to track and
improve your gait. |
