Data transmission method for use with wireless mouse

A data transmission method for use with a wireless mouse, said wireless mouse comprising a wireless signal emitter and a wireless signal receiver, said wireless signal receiver being in communication with a computer system, said wireless mouse generating a mouse displacement data in response to a triggering operation by a user, said data transmission method comprising steps of:

• periodically transmitting said mouse displacement data from said wireless signal emitter to said wireless signal receiver in every wireless transmission time interval T1, wherein said mouse displacement data includes a horizontal displacement and a vertical displacement;
• partitioning said horizontal displacement and said vertical displacement of said mouse displacement data to acquire plural horizontal sub-displacements and plural vertical sub-displacements, respectively;
• and
• periodically transmitting one of said plural horizontal sub-displacements and one of said plural vertical sub-displacements from said wireless signal receiver to said computer system in every wired transmission time interval T2, wherein said wireless transmission time interval T1 is longer than said wired transmission time interval T2,
• wherein said wireless mouse further generates a second displacement data including a second horizontal displacement and a second vertical displacement, and said step of acquiring said plural horizontal sub-displacements and said plural vertical sub-displacements comprises sub-steps of:
• combining said horizontal displacement and said second horizontal displacement as a combination horizontal displacement, combining said vertical displacement and said second vertical displacement as a combination vertical displacement, and determining a partition value according to said combination horizontal displacement and said combination vertical displacement;
• dividing said combination horizontal displacement by said partition value to obtain a horizontal quotient, a horizontal remainder and plural horizontal reserve sub-displacements, and dividing said combination vertical displacement by the partition value to obtain a vertical quotient, a vertical remainder and plural vertical reserve sub-displacements;
• and
• assigning said horizontal remainder to said plural horizontal reserve sub-displacements to obtain said plural horizontal sub-displacements, and assigning said vertical remainder to said plural vertical reserve sub-displacements to obtain said plural vertical sub-displacements.
