## Abstract

The present disclosure relates to a human-computer interaction method, apparatus, and system, and a computer-readable storage medium. The human-computer interaction method includes: displaying an eraser icon on a touch display screen according to a first touch operation of a user; adjusting at least one of a direction, a size or a shape of the eraser icon according to a second touch operation of the user, wherein the second touch operation includes at least one of a rotation operation or a deformation operation on the eraser icon; and performing an erase operation on an area to be erased according to the adjusted eraser icon.

## Claims

### Claim 1

displaying an eraser icon on a touch display screen according to a first touch operation of a user;
adjusting at least one of a direction, a size or a shape of the eraser icon according to a second touch operation of the user, wherein the second touch operation comprises at least one of a rotation operation or a deformation operation on the eraser icon, wherein the second touch operation further comprises an operation of enabling the eraser icon to be in an editable state, comprising: in case that the touch display screen is long pressed to keep displaying the eraser icon, touching another area on the touch display screen except an area where the eraser icon is displayed to enable the eraser icon to be in the editable state; and
performing an erase operation on an area to be erased according to the adjusted eraser icon.

### Claim 2 (depends on 1)

The human-computer interaction method according to claim 1, wherein the deformation operation comprises at least one of a local dragging operation of changing an outline of the eraser icon, or a zooming operation of changing the shape of the eraser icon.

### Claim 3 (depends on 1)

The human-computer interaction method according to claim 1, wherein the second touch operation further comprises at least one of a zooming operation on the eraser icon, a translation operation on the eraser icon, or a zooming operation on the area to be erased.

### Claim 4 (depends on 1)

The human-computer interaction method according to claim 1, further comprising:
adding a control section to the eraser icon according to a third touch operation of the user, wherein the control section is used for performing the erase operation on the area to be erased according to the adjusted eraser, and is moved in synchronization with the eraser icon when the erase operation is performed.

### Claim 5 (depends on 1)

The human-computer interaction method according to claim 1, wherein the eraser icon comprises a plurality of different shapes including at least one of a polygon, a circle, or an ellipse.

### Claim 6 (depends on 1)

The human-computer interaction method according to claim 1, wherein the adjusting at least one of the direction, the size or the shape of the eraser icon according to the eraser icon and the second touch operation of the user comprises:
determining the size of the eraser icon according to a contact area of the user with the touch display screen.

### Claim 7 (depends on 1)

The human-computer interaction method according to claim 1, wherein the first touch operation comprises:
a selection operation of clicking a menu bar, touching a designated area on the touch display screen, touching the touch display screen for a first predetermined time, making an erase gesture on the touch display screen, or drawing the eraser icon on the touch display screen.

### Claim 8 (depends on 1)

The human-computer interaction method according to claim 1, wherein the displaying an eraser icon on a touch display screen according to a first touch operation of a user comprises:
displaying eraser icons of a plurality of different shapes on the touch display screen according to the first touch operation of the user; and
in response to a selection of the user, displaying a selected eraser icon on the touch display screen.

### Claim 9 (depends on 8)

The human-computer interaction method according to claim 8, wherein the displaying eraser icons of a plurality of different shapes on the touch display screen according to the first touch operation of the user comprises:
sequentially arranging the eraser icons of the plurality of different shapes in a strip, a ring or a partial ring.

### Claim 10 (depends on 1)

The human-computer interaction method according to claim 1, wherein the local zooming operation further comprises changing the size of one of the interior angles of the polygonal eraser icon to match a pointed angle area of the area to be erased.

### Claim 11 (depends on 1)

The human-computer interaction method according to claim 1, wherein the eraser icon is polygonal, and the second touch operation further comprises a local zooming operation of changing one or more interior angles of the polygonal eraser icon.

### Claim 12

A human-computer interaction apparatus comprising:
a memory; and
a processor coupled to the memory, wherein the processor is configured to perform, based on instructions stored in the memory, one or more steps of a human-computer interaction method comprising:
displaying an eraser icon on a touch display screen according to a first touch operation of a user;
adjusting at least one of a direction, a size or a shape of the eraser icon according to a second touch operation of the user, wherein the second touch operation comprises at least one of a rotation operation or a deformation operation on the eraser icon, wherein the second touch operation further comprises an operation of enabling the eraser icon to be in an editable state, comprising: in case that the touch display screen is long pressed to keep displaying the eraser icon, touching another area on the touch display screen except an area where the eraser icon is displayed to enable the eraser icon to be in the editable state; and
performing an erase operation on an area to be erased according to the adjusted eraser icon.

### Claim 13 (depends on 12)

A human-computer interaction system, comprising:
the human-computer interaction apparatus according to claim 12; and
a touch display screen.

### Claim 14 (depends on 12)

The human-computer interaction apparatus according to claim 12, wherein the deformation operation comprises at least one of a local dragging operation of changing an outline of the eraser icon, or a zooming operation of changing the shape of the eraser icon.

### Claim 15 (depends on 12)

The human-computer interaction apparatus according to claim 12, wherein the second touch operation further comprises at least one of a zooming operation on the eraser icon, a translation operation on the eraser icon, or a zooming operation on the area to be erased.

### Claim 16 (depends on 12)

The human-computer interaction apparatus according to claim 12, wherein the processor is further configured to add a control section to the eraser icon according to a third touch operation of the user, wherein the control section is used for performing the erase operation on the area to be erased according to the adjusted eraser, and is moved in synchronization with the eraser icon when the erase operation is performed.

### Claim 17 (depends on 12)
