According to one embodiment, an information processing device has processing circuitry and a memory. The processing circuitry is configured to acquire myoelectric potential of one part of a body of a user, determine whether the myoelectric potential is higher than reference myoelectric potential, switch autonomous driving to manual driving when the myoelectric potential is higher than the reference myoelectric potential, and output running control information to a mobile object after switching the autonomous driving to the manual driving. The memory is configured to store information that is required for processing that the processing circuitry executes.
