Method for minimising motion sickness for head-mountable extended reality

Non-transitory computer-readable storage medium storing a computer program comprising instructions that, when executed by a processor, causes the head-mountable processing system to perform a method to operate a head-mountable processing system, the method comprising:

• comparing a visual motion of a sequence of images for display by the head-mountable processing system to a threshold;
• and
• based on the comparison between the visual motion of the sequence of images for display by the head-mountable processing system and the threshold,
• generating one or more control signals based upon the visual motion of the sequence of images for display by the head-mountable processing system;
• and
• transmitting the generated one or more control signals to a plurality of transducers to stimulate a wearer's vestibular systems to control the wearer's sense of balance.

A head-mountable processing system comprising:

• a head-mountable device;
• a plurality of transducers for stimulation of the vestibular system of a wearer;
• a processing circuit to compare a visual motion of a sequence of images for display by the head-mountable processing system to a threshold;
• a control circuit to generate, based on the comparison between the visual motion of the sequence of images for display by the head-mountable processing system and the threshold, one or more control signals based upon the visual motion of the sequence of images for display by the head-mountable processing system;
• a communication circuit to transmit one or more control signals to the plurality of transducers to control stimulation of a wearer's vestibular system to control the wearer's sense of balance.
