and the initial velocity processing unit is used for acquiring the initial velocity of the linear velocity and the initial velocity of the angular velocity after receiving the release control information sent by the contact capture unit and sending the acquired initial velocity of the linear velocity and the acquired initial velocity of the angular velocity to the inertia processing unit.

The method for realizing the dragging effect of the window object specifically comprises the following steps:

Timer 2T_iThe method for acquiring the initial velocity of the linear velocity corresponding to the period comprises the following steps:

V_i＝V_i-1-V_dec*Tg；

wherein, V_decThe deceleration is the linear velocity deceleration, which can be preset by a user or a system according to the actual situation, and is equivalent to adjusting the friction coefficient of the linear velocity; the first Timer2 period, V, after the input device releases the window object₁The linear velocity initial velocity V is sent by the dragging processing module; tg is the period of Timer2, which may be preset by the user or the system;

α_i＝(Va_i-Va_dec*Tg)*Tg

wherein, Va_iIs the Tth time of Timer2_iAngular velocity initial velocity corresponding to the period;

if Tg is equal to Δ t, and Δ t is set as the standard unit time, the above equation can be simplified as:

(ΔX，ΔY)＝(V_i.X-V_dec，V_i.Y-V_dec)

α_i＝(Va_i-Va_dec)

that is, taking Tg ═ Δ t as the unit time of the velocity sampling, the inertia processing, and the window object position refreshing can greatly simplify the amount of calculation.

When the displacement amount and the rotation amount of the inertial movement of the current time period window object obtained by the above equations are equal to or less than 0, the inertial processing is ended.

After the window object receives the displacement amount and the rotation amount sent by the inertia processing unit 103 each time, the center coordinate attribute value and the rotation angle attribute value of the window object are set as follows:

CenterX＝CenterX+ΔX
