1. A haptic generation and integration system for multimedia devices comprising: a first multimedia video/audio recording device comprising a first sensor to measure physical magnitudes related with the recording action and a first computer platform including a first processor and a first set of machine-readable instructions, wherein said first set of machine-readable instructions are configured to process the physical magnitudes to generate control patterns depending on their frequency and intensity, integrate those patterns synchronized with the audio/video information, and store the resulting multimedia information locally in a memory or remotely in a server; and a second multimedia player device comprising at least an actuator to generate haptic information related to physical magnitudes, and a second computer platform including a second processor and a second set of machine-readable instructions; wherein said first multimedia device is configured to record haptic multimedia information, integrate it with the rest of the multimedia content and send it through a network to be used by said second multimedia player device, wherein said second set of machine-readable instructions is configured to play said multimedia information, extract the related haptic information and generate control signals to haptic actuators synchronized to the recorded multimedia information, and wherein the physical haptic information is integrated synchronously in the multimedia file by using the lowest part of the spectrum in at least one of the multimedia audio tracks.
