Claim Text:
1. A method for switching an operation mode of a data processing device having a screen supporting a multi-touch control function, wherein the data processing device has a first operation mode where an angle between the data processing device and a plane in which the data processing device is placed is within a first angle range, and a second operation mode where the angle between the data processing device and the plane in which the data processing device is placed is within a second angle range, any of the angle within the first angle range is greater than any of the angle within the second angle range; wherein the second operation mode is different from the first operation mode, and the second operation mode is a mode where at least two users simultaneously operate different applications or a mode where at least three users simultaneously operate the same application, the same application supporting the at least three users' simultaneous operations; wherein the method comprises: detecting whether a value of an angle between the data processing device and a plane in which the data processing device is placed is adjusted from a first angle value to a second angle value; judging whether an operation mode corresponding to the second angle value is the same as an operation mode corresponding to the first angle value in response to the adjusting being detected; generating a switching instruction for switching the operation mode in response to determining the operation mode corresponding to the second angle value is different from the operation mode corresponding to the first angle value; switching the operation mode of the data processing device from the operation mode corresponding to the first angle value to the operation mode corresponding to the second angle value based on the switching instruction, wherein the operation mode corresponding to the second angle value is one of the first or second operation mode; wherein in the second operation mode, the screen has at least two display areas, and a display direction in which content is displayed in the at least two display areas is changed according to a display direction control instruction for controlling the display direction; wherein the display direction control instruction is generated by the data processing device by detecting whether there is a user in a direction and whether to display the content towards the direction.
