System and method to alter a user interface of a self-driving vehicle in cases of perceived emergency based on accelerations of a wearable user device

A system for preventing an accident of a self-driving vehicle, comprising:

• user input circuitry;
• and
• control circuitry configured to:
• generate for display media content on a user interface for a self-driving vehicle;
• detect a wearable user device within the self-driving vehicle;
• detect an acceleration of the wearable user device;
• compute an acceleration value of the wearable user device from the detected acceleration;
• retrieve the current speed of the self-driving vehicle;
• determine a threshold acceleration value for the wearable user device with respect to the self-driving vehicle based on the current speed of the self-driving vehicle;
• determine whether the acceleration value of the wearable user device exceeds the threshold acceleration value of the wearable user device that was determined based on the current speed of the self-driving vehicle;
• in response to determining the acceleration value of the wearable user device exceeds the threshold acceleration value, remove the media content from the user interface for the self-driving vehicle;
• and
• in response to determining the acceleration value of the wearable user device does not exceed the threshold acceleration value, to:
• determine whether the acceleration value of the wearable user device falls within limits of a second threshold acceleration value proximity;
• and
• in response to determining that the acceleration value of the wearable user device falls within the limits of the second threshold acceleration value proximity, alter the media content on the user interface for the self-driving vehicle, wherein, when altering the media content on the user interface for the self-driving vehicle, to:
• alter the user interface, from a first user interface to a second user interface, wherein the second user interface comprises a translucent user interface;
• detect a second acceleration value of the wearable user device within a third threshold acceleration value proximity;
• and
• in response to detecting the second acceleration value of the wearable user device within the third threshold acceleration value proximity, revert the user interface from the second user interface to the first user interface.
