Claim:
1. A method of detecting erroneous measurements of a position of a device, the device comprising position measurement means, the method comprising: determining a state of motion of a user of the device from a plurality of possible states; predicting a predicted position of the device using a plurality of models, wherein each model has a separate prediction and output functions corresponding to a respective one of the plurality of possible states, and the determined state of motion of the user, wherein the predicting includes assigning weights to outputs of the plurality of models to determine an influence of each of the plurality of models on the predicted position; measuring a measured position of the device using the position measurement means; comparing the predicted position of the device to the measured position of the device; and determining whether the measured position of the device is erroneous based on a result of the step of comparing.
