Claim 8:
9. A method for estimating a physical state of a movable object, the movable object comprising an inertial measurement unit, the method comprising: receiving a probability mass function comprising probabilities for each movement class of a first group of at least two movement classes, wherein the movement classes of the first group being determined using sensor data from the inertial measurement unit; receiving at least one additional probability mass function associated with a second group of at least two movement classes, wherein the additional probability mass function has been acquired using additional information different from the sensor data; combining the probability mass function and the additional probability mass function to acquire a combined probability mass function over the movement classes of the first group and the second group; selecting a movement class comprising the highest probability from the combined probability mass function; and
estimating the physical state of the movable object using a movement model of the selected movement class, wherein each movement class is either a movement state or a movement model, and wherein the additional information different from the sensor data concerns information from other devices in the vicinity of the object determined via device to device (D2D) data exchanged directly with the other devices.
