The present invention relates to systems and methods for reliably detecting motion control of mobile devices executing virtual tour applications. In one embodiment, a computerized mobile device reliably detects angular rotations. The mobile device includes a magnetometer for generating directional values representing the respective angular rotations. The mobile device detects abrupt change(s) in additional directional values relative to the prior directional values, and if an abrupt change in an additional directional value is detected, then an appropriate weight is assigned to the additional data value. In addition to generating directional values, the magnetometer may also generate corresponding magnitude values. The mobile device evaluates the corresponding magnitude values and if an amplitude of a magnitude value is greater than a threshold, then the mobile device decreases a confidence value associated with the corresponding directional value.
