A method for controlling a function in a touch device, the method comprising: receiving a touch event input through a function button displayed on a screen; and executing a unique function allocated to the function button when the touch event input is released within a predetermined time; and when the touch event input is not released within the predetermined time: displaying a first option menu or option controller; setting a first option value associated with the unique function according to movement of the touch event input relative to the first option menu or option controller; and in response to detecting movement of the touch event input in a direction different to the direction for setting the first option value: temporarily storing the first option value of the point relative to the first option menu or option controller at which movement of the touch event input in a direction different to the direction for setting the first option value is detected; displaying a second option menu or option controller; setting a second option value associated with the unique function according to an option value of a point relative to the second option menu or option controller at which the touch event input is released; and executing the unique function allocated to the function button based on the first option value and the second option value. receiving a touch event input through a function button displayed on a screen; and executing a unique function allocated to the function button when the touch event input is released within a predetermined time; and when the touch event input is not released within the predetermined time: displaying a first option menu or option controller; setting a first option value associated with the unique function according to movement of the touch event input relative to the first option menu or option controller; and in response to detecting movement of the touch event input in a direction different to the direction for setting the first option value: temporarily storing the first option value of the point relative to the first option menu or option controller at which movement of the touch event input in a direction different to the direction for setting the first option value is detected; displaying a second option menu or option controller; setting a second option value associated with the unique function according to an option value of a point relative to the second option menu or option controller at which the touch event input is released; and executing the unique function allocated to the function button based on the first option value and the second option value. displaying a first option menu or option controller; setting a first option value associated with the unique function according to movement of the touch event input relative to the first option menu or option controller; and in response to detecting movement of the touch event input in a direction different to the direction for setting the first option value: temporarily storing the first option value of the point relative to the first option menu or option controller at which movement of the touch event input in a direction different to the direction for setting the first option value is detected; displaying a second option menu or option controller; setting a second option value associated with the unique function according to an option value of a point relative to the second option menu or option controller at which the touch event input is released; and executing the unique function allocated to the function button based on the first option value and the second option value. temporarily storing the first option value of the point relative to the first option menu or option controller at which movement of the touch event input in a direction different to the direction for setting the first option value is detected; displaying a second option menu or option controller; setting a second option value associated with the unique function according to an option value of a point relative to the second option menu or option controller at which the touch event input is released; and executing the unique function allocated to the function button based on the first option value and the second option value.
