Your while loop is blocking the main update loop, so the tracker will never update. You should never use time.sleep in the main thread. Instead, register a function to be called every 0.25 seconds and print the tracker values within that function:

import vizact
def PrintValues():
    print glasses.getPosition()
    print glasses.getQuat()

vizact.ontimer(0.25,PrintValues)
