Graph 2: Acceleration change curves of remote control being dropped
D2T
The remote may be left unused: This means it must be detected
that the acceleration on each axis doesn’t change
D3T
Remote may receive a shock: A sudden high rise in acceleration is
to be detected.
D4T
The remote may be in an invalid position: This requires detection of
how much the acceleration for each axis differs from the initial state
(see Inclination / position check).
D5T
Losing balance: Depending on the direction and intensity of
stumbling or slipping, the data for this case can have various
shapes. However, in general a loss of balance starts with a sudden
increase in acceleration (the cause of the stumbling, e.g. stepping
