## Abstract

A touch method and a touch device of a computer system are provided. The touch method comprises the steps outlined below.. A function control mode is performed. A graphic control frame comprising a first width having a default ratio relative to a second width of a touch pad of the touch device is displayed on a display device of the computer system. A touch input is received A displacement track and a position of the touch input are determined. At least one graphic control option on the graphic control frame is controlled according to the displacement track, the position of the touch input and the default ratio. The touch device used in the computer system is disclosed herein as ell.

## Claims

### Claim 1

A touch device used in a computer system, wherein the touch device comprises:
a touch pad to receive a touch input;
a determining module to determine a displacement track and a position of the touch input; and
a control module to activate a function control mode to display a graphic control frame comprising a first width having a default ratio relative to a second width of the touch pad on a display device of the computer system;
wherein the control module further controls at least one graphic control option on the graphic control frame according to the displacement track of the touch input, the position of the touch input and the default ratio.

### Claim 2 (depends on 1)

The touch device of claim 1, wherein the default ratio between the first and the second width of the graphic control frame and the touch pad is 1:1.

### Claim 3 (depends on 1)

The touch device of claim 1, wherein the control module controls the at least one graphic control option by using an absolute coordinate system.

### Claim 4 (depends on 1)

The touch device of claim 1, wherein a characteristic of the displacement track is selected from a group consisting of an initial position, a displacement amount, a shape or the combination of elements of the group.

### Claim 5 (depends on 1)

The touch device of claim 1, wherein the graphic control option is selected from a group consisting of a knob, an adjusting bar, a scrolling bar, a page curl or the combination of elements of the group.

### Claim 6 (depends on 1)

The touch device of claim 1, wherein the control module further determines an area and a shape of the touch input.

### Claim 7 (depends on 6)

The touch device of claim 6, wherein the control module does not perform any controlling process according to the touch input when the area of the touch input is larger than a predetermined value or when the shape of the touch input matches a predetermined pattern.

### Claim 8

A touch method used in a touch device of a computer system, wherein the touch method comprises:
performing a function control mode;
displaying a graphic control frame comprising a first width having a default ratio relative to a second width of a touch pad of the touch device on a display device of the computer system;
receiving a touch input;
determining a displacement track and a position of the touch input; and
controlling at least one graphic control option on the graphic control frame according to the displacement track of the touch input, the position of the touch input and the specific ratio.

### Claim 9 (depends on 8)

The touch method of claim 8, wherein a characteristic of the displacement track is selected from a group consisting of an initial position, a displacement amount, a shape or the combination of elements of the group.

### Claim 10 (depends on 8)

The touch method of claim 8, wherein the default ratio between the first and the second width of the graphic control frame and the touch pad is 1:1.

### Claim 11 (depends on 8)

The touch method of claim 8, wherein the at least one graphic control option is controlled by using an absolute coordinate system.

### Claim 12 (depends on 8)

The touch method of claim 8, wherein the graphic control option is selected from a group consisting of a knob, an adjusting bar, a scrolling bar, a page curl or the combination of elements of the group.

### Claim 13 (depends on 8)

The touch method of claim 8, further comprising a step of determining an area and a shape of the touch input.

### Claim 14 (depends on 13)

The touch method of claim 13, wherein none of controlling process is performed according to the touch input when the area of the touch input is larger than a predetermined value or when the shape of the touch input matches a predetermined pattern.
