The Sixaxis features finer analog sensitivity than the DualShock 2, increased to 10-bit precision from the 8-bit precision of the DualShock 2.[6] The controller also uses both analog and digital signals simultaneously at all times during gameplay. The frame beneath the L2 and R2 buttons has been omitted and these buttons have been made trigger-like, with the range of travel determining the degree of analog input rather than the range of pressure. In the place of the "Analog" mode button of previous Sony dual analog controllers (Dual Analog, DualShock and DualShock 2) is a jewel-like "PS button" with the PlayStation logo, which can be used to access the home menu or XMB (after system software version 2.40[7]), switch controller inputs and turn the console or the controller on or off.
