Abstract
Systems, methods, devices and computer-readable storage mediums are disclosed for device state estimation with body-fixed assumption. In some implementations, a method comprises: determining, by a device, a rotational velocity of a user of the device based on a sensor signal; determining, by the device, user speed; determining, by the device, user acceleration based on the user speed and the rotational velocity of the user; and updating a user state estimator based on the user acceleration.
