In our earlier researches we examined the reliability and accuracy of sensors used in outdoor positioning. Results have shown that they are not as reliable as many think. So the question rightly arises: what sensor could be the solution for indoor navigation. The sensitivity and resilience of smartphone sensors are currently unknown, and their reliability is also questionable because of the many distracting factors. However, studies also show that it is possible to decrease distraction-caused errors with the help of appropriate algorithms. Hence first we must define sensitivity of sensors and understand their operational principles to find the appropriate algorithms.
