Abstract:
1. 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 T 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 T wherein said step of acquiring said plural horizontal sub-displacements and said plural vertical sub-displacements comprises sub-steps of: determining a partition value according to said horizontal displacement and said vertical displacement; dividing said horizontal displacement by said partition value to obtain a horizontal quotient, a horizontal remainder and plural horizontal reserve sub-displacements, and dividing said 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.
