Abstract:
1. A method for setting sensitivity of a rolling type input apparatus, comprising: detecting, by the rolling type input apparatus, parameters reflecting speeds and amplitudes of a plurality of operations that a user rolls a rolling device to determine habits of operations that the user uses the rolling device in the rolling type input apparatus; setting, by the rolling type input apparatus, a threshold value based on the detected parameters automatically, wherein the threshold value corresponds to the habits of operations that the user uses the rolling device in the rolling type input apparatus, the rolling type input apparatus is configured to detect a rolling direction and rolling distance of the rolling device in the rolling process of the rolling device, generate corresponding interrupts according to the rolling direction and rolling distance of the rolling device, identify the number and directions of the interrupts, and respond to the interrupts for a preset number of times by transmitting a moving event signal for controlling a cursor to move on a screen when the number of the interrupts in the same direction reaches the threshold value, wherein the parameters comprises a number of interrupts generated when the rolling device is rolled for a preset number of times, and the threshold value is set at least partially based on a value which is obtained by dividing the number of interrupts generated when the rolling device is rolled for a preset number of times by number of moving events which have been finished by the cursor on the screen when the rolling device is rolled for a preset number of times.
