1. A method for smoothing evolution of a variable depending on an orientation of a device, the method comprising:

  • determining an adjusted angular velocity (Ω

    s,n) based on a measured angular velocity (ω

    n) and an estimated angular velocity (Ω

    f,n), such that to satisfy one or more predefined constraints, including at least one constraint for masking of any of a correction and an artifact;

    determining a current value (x) of the variable according to an adjusted estimate of the current orientation (qs,n) of the device obtained using the adjusted angular velocity (Ω

    s,n); and

    outputting the current value (x) of the variable.
