Abstract

A device (1) comprising: sensor means (2) for providing first field information (11-13) defining at least a part of a first field, and for providing second field information defining at least a part of a second field Field information (14, 15), the device is equipped with an updater (4) for updating the parameters of the first and / or second field via at least one iteration based on a criterion in order to become more reliable and user-friendly . The field may be a gravitational field and / or the Earth's magnetic field and / or a further field. The parameters include the amplitude of the field and the dot product of the field. Criterion-based iterations include amplitude functions and dot product functions. The amplitude function defines the new amplitude as a function of the old and updated amplitudes, and the dot product function defines the new dot product as a function of the old and updated dot products. Criterion-based iterations further include one-dimensional criteria and / or rectangular, hyperbolic and / or truncated hyperbolic two-dimensional criteria all defining thresholds.

Description

technical field [0001] The invention relates to an apparatus comprising a sensor device and an updater, and also to an updater, a method, a processor program product and a data carrier. Background technique [0002] Examples of such devices are personal computers, electronic compasses, wrist watches, navigation aids, mobile phones, personal digital assistants and other handheld devices. The sensor device comprises, for example, a magnetometer or a geomagnetic force detector and / or an accelerometer or a tilt angle detector. [0003] A prior art device is known from US 2004 / 0172838, which patent publication discloses a device with sensor means comprising a geomagnetism detector and an inclination detector. Magnetometers provide magnetism information that defines the Earth's magnetism, while inclination detectors provide inclination information that defines inclination. The geomagnetism detector detects a first axis component and a second axis component of the geomagnetism, a...
