Abstract

The invention discloses a method for accelerating cursor movement on a touch pad in a double-finger sliding mode. The method comprises the following steps of: if detecting that double fingers are in contact with the touch pad, the double fingers slide along the same direction in the set initial period of time and the X direction distance Dx(X1t-X2t) and the Y direction distance Dy(Y1t-Y2t) between the double fingers maintain in the range of spacing tolerance d, switching touch pad software to a cursor acceleration mode and accelerating cursor movement according to the set multiples; and if determining that the touch pad is slid by a single finger in the set initial contact time, moving the cursor at the set normal speed. The cursor speed can be changed by the simple method only by easily sliding the two fingertips to maintain a rough distance, without particularly paying attention to gesture and even without moving a palm to a great extent; and the method can be flexibly grasped without long-term learning, so the method is very convenient.

Description

The two methods that refer to that slip acceleration cursor moves of Trackpad

Technical field:

The present invention relates to the touch pad technology field, the cursor that specifically relates to a kind of Trackpad quickens moving method.

Background technology:

The screen area of general computer is much larger than the Trackpad area, and the sliding speed of cursor on screen depends on the setting speed and the finger motion speed of control panel.But general design is to point when slipping over the Trackpad lateral length, and cursor moves half lateral length on screen, because the too fast target of then missing easily, the palpus readjustment is revised and brought inconvenience; If then increase the slip number of times too slowly, the user points easy fatigue.

The insider has developed two kinds of methods can operate cursor by two-speed, and a kind of is with finger contact area decision cursor speed, if finger tip touches then to slide at a slow speed, if afterburning the contact then with large tracts of land slided fast.The shortcoming of this method is: because everyone finger difference, be difficult to define the big or small boundary line of finger, though can carry out individual settings according to everyone, but in practical operation, if will finger with than large tracts of land contact, need whole finger is crooked and horizontal by existing less angle contact Trackpad, also need in addition palm is compared big displacement, operate quite dumb, the therefore general less employing of this mode.Another two-speed operational light calibration method is to utilize the different sliding speeds of finger at Trackpad, and cursor is carried out moving of friction speed, and this mode is simple to operate, and does not have the dumb problem of first method; The shortcoming of this mode is that translational speed and sliding distance are difficult to judge, the user must be through study after a while, otherwise be difficult to grasp, so also less employing.

Summary of the invention:

The objective of the invention is to the weak point that exists at prior art and provide a kind of Trackpad two refer to slide quicken the methods that cursor moves, it have simple to operate, grasp flexible characteristic.

For achieving the above object, the two methods that refer to that slip acceleration cursor moves of Trackpad of the present invention comprise the steps: if detect two abutment Trackpads, and two finger the in initial a period of time of setting for sliding in the same way, and the distance D x of directions X (X1t-X2t) remains within the spacing tolerance d with Y direction distance D y (Y1t-Y2t) always between two fingers, then Trackpad software switches to the cursor aero mode, makes cursor accelerated motion according to the multiple of setting; Singly refer to slide if in the initial duration of contact of setting, be judged as, then normal speed moving cursor to set.

Preferred as technique scheme.Described Trackpad is the Trackpad that is applied to notebook or desktop PC keyboard or closed-circuit television telepilot, and the Trackpad support refers to control mode touch mode more.

Preferred as technique scheme, computer is provided with operation interface, can change two acceleration multiples of sliding in the same way of referring to, and after the user set, computer system sent signal to Trackpad and changes setting value.

Preferred as technique scheme, computer is provided with operation interface, can change two spacing tolerances that refer to, and after the user set, computer system sent signal to Trackpad and changes setting value.

Beneficial effect of the present invention is: it can change cursor speed with simple method, as long as like a cork two finger tips are slided maintenance distance roughly, needn't pay special attention to gesture, even mobile significantly palm, need could not grasp flexibly through the long learning period yet, very convenient.

Description of drawings:

The present invention is described further below in conjunction with accompanying drawing:

Fig. 1 is a process flow diagram of the present invention.

Embodiment:

Therefore the following stated does not limit protection scope of the present invention only for embodying the preferred embodiment of the principle of the invention.

See shown in Figure 1: finger contact Trackpad, be failure to actuate earlier, at first judge it is singly to refer to or two finger; Judge the finger motion state in initial a period of time of setting simultaneously, its method is to refer to position (X1 every a detecting time period detecting two, Y1), (X2, Y2), and directions X distance D x (X1t-X2t) and Y direction distance D y (Y1t-Y2t) between the two fingers of calculating, if the directions X distance D x (X1t-X2t) between two the finger remains in the spacing tolerance d with Y direction distance D y (Y1t-Y2t) always, then being judged as finger slides in the same way, Trackpad software switches to the cursor aero mode, according to the multiple of setting (1.2～3 times) cursor speed is carried out multiple and moves.

Singly refer to slide if in the initial duration of contact of setting, be judged as, then normal speed moving cursor to set; If the directions X distance D x between two finger the and Y direction distance D y are greater than tolerance d and gradually change, then enter other and refer to steer mode more, if two indication is left and non-displacement after touch, contact the residence time and instruction is sent in two finger positions according to finger.Finger leaves the answer initial state.

The multiple method of decision cursor speed is: set an operation interface on computers, and the acceleration multiple in the time of can changing two fingers and slide in the same way, after the user set, computer system sent signal to Trackpad and changes setting value.In addition, operation interface also can be changed two spacing tolerances that refer to, after the user set, computer system sent signal to Trackpad and changes setting value.

Claims
