Background technology

Recently, because advantage such as simple, light and cheap, Trackpad has been widely applied in the various electronic products, to replace input media originally.Present Trackpad has a two-dimensional model and a dimensional pattern.Fig. 1 and Fig. 2 are the inductors 100 and 101 of the two-dimensional model Trackpad of two kinds of Common Shape, it has many horizontal direction lines of induction 102 and the vertical direction line of induction 104, when finger touches should the two dimension Trackpad, the line of induction 102 of touched position and 104 is sent to the main frame that connects this two dimension Trackpad with message, thereby learn the coordinate of this touch position, when finger is mobile on this two dimension Trackpad, main frame is judged the moving direction of finger according to the coordinate difference of front and back, and produces corresponding action.

Yet, when the user only wants to carry out level or vertical direction when moving, the two dimension Trackpad can't be controlled very accurately, for example shown in Figure 3, the user wants to allow the scroll bar of window to the right during scrolling, is to move horizontally from left to right on two-dimentional Trackpad 105 to point 106, but during moving, finger 106 may be offset up or down, thereby causes at scroll bar also scrolling up or down in the scrolling to the right.

U.S. patent application case discloses the touch control panel inductor of No. 2004/0252109 an a kind of dimensional pattern of proposition, produce corresponding action by moving to left-handed or dextrorotation of finger sensing, for example, up and down, about and action such as plus-minus, do not influence judgement even therefore the radian that rotates is irregular yet.Though this one dimension Trackpad can clearly be judged positive negative direction, but can't provide multifarious function as two-dimentional Trackpad, handwriting identification function for example is if want to increase extra function, must increase extra button or other input media, cost will be improved.

Fig. 4 and Fig. 5 are front and the schematic rear views that is applied in the input media 108 on the iPod at present, it has been used U.S. patent application case and discloses disclosed one-dimensional inductor 110 No. 2004/0252109, when finger on circular inductor 110 during left-handed or dextrorotation, can make the menu scrolling or regulate volume, four direction up and down and center at inductor 110 respectively are provided with a

button

112 and 114 so that extra function to be provided, for example, activate/stop, the fast commentaries on classics, reversing, menu and definite, because inductor 110 is an annulus, therefore center button 112 has a style of one's own and can't reach integrated effect with inductor 110, the complete circle that is shaped as if inductor 110, though can reach integrated effect, but when pushing center button 112, inductor 110 will be pushed and produce depression with finger, if the offset of pushing the center, just may other button 114 of false touch, as shown in Figure 6, cause incorrect operation.

Therefore, a kind ofly supporting one dimension and two-dimensional model, integrating keys and reach integrated multi-functional Trackpad, is to be the institute Ji.

Summary of the invention

Embodiment

Fig. 7 is the functional block diagram of touch sensor capable of supporting 1-D and 2-D mode 200 of the present invention, and Fig. 8 is an operation chart.When finger 214 contact surface plates 212,2D signal Sd is sent to two-dimensional coordinate processor 204 in inductor 202 positions of finger sensing 214 on panel 212, to produce two-dimensional coordinate (x, y), under two-dimensional model, two-dimensional coordinate (x, y) directly be sent to main frame 206, therefore main frame 206 is learnt and is pointed 214 present positions, when finger 214 is mobile on panel 212, the coordinate difference was given main frame 206 before and after two-dimensional coordinate processor 204 was sent, and made it can be in response to the corresponding action of mobile generation of finger 214.And under a dimensional pattern, two-dimensional coordinate (x, y) being sent to coordinate converter 208 is converted to one-dimensional signal Ss, and a dimension coordinate processor 210 produces a dimension coordinate θ according to one-dimensional signal Ss and gives main frame 206.In this embodiment, a dimension coordinate θ is the angle between finger 214 and the center line 215.As shown in Figure 9, when finger 214 was mobile on panel 212, a dimension coordinate θ will be along with change, and the coordinate difference was given main frame 206 before and after a dimension coordinate processor 210 was sent, and made it can judge that moving of finger 214 is left-handed or dextrorotation, and produced corresponding action.Trackpad of the present invention can be supported a two dimension and a dimensional pattern, therefore has both advantages concurrently, and the user can select a two-dimensional model or a dimensional pattern as required.

The control method of mode switch can be utilized finger 214 to be put on the panel 212 at that time position and decide and be one dimension or two-dimensional model, for example, as shown in Figure 8, panel 212 is divided into perimeter 216 and interior zone 218, when finger 214 positions that fall externally regional 216 the time, touch sensing device 200 enters a dimensional pattern, and when pointing 214 positions that fall at interior zone 218, touch sensing device 200 enters two-dimensional model.In this embodiment, because perimeter 216 is a concentric circles with interior zone 218, can with the setting coordinate in the center of circle initial point (0 therefore, 0), suppose the coordinate of finger 214 when being put into panel 212 for (x, y), can try to achieve finger 214 to the distance between the center of circle (0,0) according to the radius of a circle formula:

R = \sqrt{x^{2} + y^{2}}

Formula 1

Therefore the radius of interior zone 218 is r again, and as R during greater than r, expression finger 214 drops on perimeter 216, and as R during less than r, expression is pointed 214 and dropped on interior zone 218.In other embodiments, panel 212 is divided into two or more zones.In other embodiment, the zone that panel 212 is divided is irregular shape, and the shape of panel 212 also is not limited to circle, and other geometric figure as rectangle, triangle or irregular shape, also all is suitable for.

Also can switch one dimension or two-dimensional model by the finger number of induction on panel 212, for example, when a finger was only arranged on the panel 212, touch sensing device 200 operated in two-dimensional model, when two fingers were arranged on the panel 212, touch sensing device 200 switched to a dimensional pattern.In addition, also can utilize gesture to reach the function of mode switch, for example, finger connects a secondary, i.e. switch mode on panel 212.

Figure 10 is the another embodiment of touch sensor capable of supporting 1-D and 2-D mode 200 of the present invention, wherein comprise inductor 202 equally, two-dimensional coordinate processor 204, main frame 206, a coordinate converter 28 and a dimension coordinate processor 210, when finger touches the panel of touch sensing device 200,2D signal Sd is sent to two-dimensional coordinate processor 204 and coordinate converter 208 in the position of inductor 202 finger sensing, two-dimensional coordinate processor 204 produces two-dimensional coordinate (x according to 2D signal Sd, y) give main frame 206, coordinate converter 208 is then changed 2D signal Sd and is given a dimension coordinate processor 210 for one-dimensional signal Ss, give main frame 206 to produce a dimension coordinate θ, main frame can judge voluntarily needed be two-dimensional coordinate (x, y) or a dimension coordinate θ.

Figure 11 is the schematic rear view of the inductor 202 of Trackpad of the present invention, which is provided with 5

buttons

2022 and 2024, button 2022 is separately positioned on inductor 202 edge of four direction up and down, 2024 centres of button at inductor 202, if the user is when pushing center button 2024, because of other button 2022 that has been offset the center false touch, can be by the algorithm of software or firmware, preferentially trigger the function of button 2024, and ignore the false touch of button 2022.Figure 12 is button 2022 and 2024 a signal timing diagram among Figure 11, wherein waveform 300 is buttons 2024, waveform 302 is buttons 2022, when the user pushes center button 2024, if the offset of pushing the center, make that the accurate position of button 2024 transfers high levle to after, button 2022 also transfers high levle to because of false touch, default algorithm will preferentially be carried out the function of button 2024 because of button 2024 triggers earlier this moment, and ignore button 2022, avoid incorrect operation.

Trackpad of the present invention utilizes algorithm to avoid because of inductor 202 depressions cause the maloperation of false touch, so can reach integrated effect after integrating keys when pushing center key 2024.

Figure 13 and Figure 14 show another embodiment of integrating keys of the present invention, and wherein Figure 13 is the front that shows inductor 202, and Figure 14 shows the back side of inductor 202.With reference to Figure 13 and Figure 14, the front of inductor 202 has the horizontal direction line of induction 102 and the vertical direction line of induction 104, and position is provided with button 2024 in the middle of it, be provided with 4 buttons at the back side of inductor 202 respectively at inductor 202 edge of four direction up and down, in this embodiment, because center button 2024 and other 4 buttons 2022 are on the not coplanar of inductor 202, therefore, when pushing center button 2024, even the offset of pushing the center, also be unlikely touch of key-press by accident 2022, so also can reach integrated effect.
