A method for interacting with a video by a motion detector is disclosed. For example, a first amplifier structure is arranged to produce a negative-going bias correction signal when a bandgap voltage reference increases as operating temperatures rise and a second amplifier structure is arranged to produce a positive-going bias correction signal when the bandgap voltage reference increases as operating temperatures rise. Further the invention refers to a corresponding wireless device and to a method for integrating such an antenna structure in a wireless device. Also, the location of each shared region of each column is shifted by one row in each adjacent column. The step of establishing the group comprising the step of confirming the establishment of the group between the users of the wireless terminals using a message that is transmitted using the second circuit.
