Abstract

The user interacts with a virtual workspace through guiding a cursor across a display screen for visual representation of the workspace. A user-interface provides a tactile response which is user-programmable and enables specifying tactile fields at particular locations in the virtual workspace. The user navigates through the virtual workspace by guiding the cursor while experiencing the tactile response fields programmed in advance.

Claims

1. An information processing system for enabling a user to navigate through a virtual workspace, said system comprising:

a display screen for visual representation of the virtual workspace; and

a user-interface device for a user to guide a cursor object across the display screen and for providing a tactile response to the user while guiding the cursor object,

wherein, prior to navigating through the virtual workspace under the guidance of a programmed tactile response, the system renders user-programmable at least one of the following parameters of the tactile response, corresponding with a tactile field in the virtual workspace, as selected from the group consisting of strength, size, and shape, and

wherein the system enables the user to program a mapping of an adjusted particular tactile field onto the virtual workspace, and wherein the tactile response is programmable to aid the cursor movement.

2. The system of claim 1, wherein the system provides a pictorial representation of the tactile field on the screen to support the programming.

3. The system of claim 2, further comprising enabling operating on a particular one of the parameters by operating on the pictorial representation.

4. The system of claim 1, comprising a library of a plurality of tactile fields, each respective tactile field thereof for being mapped onto the virtual workspace upon selection by the user.

5. The system of claim 1, enabling the user to program the tactile response to be conditionally dependent on a specific state of the virtual workspace.

6. The system of claim 1, wherein, prior to navigating through the virtual workspace under guidance of the programmed tactile response, a parameter of the tactile response that is rendered user-programmable by the system further comprises a dynamic behavior of the tactile field.

7. The system of claim 6, wherein said dynamic behavior is programmable to cause the user to experience a time-dependent force through the user-interface when the cursor is within a local range of the tactile field.

8. The system of claim 6, wherein said dynamic behavior is programmable to have the tactile field fade away in the course of time as independent of cursor movement.

9. The system of claim 6, wherein said dynamic behavior is programmable to have the tactile field fade away in the course of time after a particular time has elapsed since the user last carrier out an action in the virtual workspace.

10. The system of claim 1, further comprising a user-interface device producing both negative and positive reaction forces when the cursor is guided through a tactile field.

11. A method of enabling a user to navigate through a virtual workspace, said method comprising the steps of:

providing a visual representation of the virtual workspace on a display screen;

enabling a user to guide a cursor object across the display screen;

providing a tactile response to the user while guiding the cursor object; and

enabling the user to program a parameter of the tactile response prior to navigating through the virtual workspace, wherein the tactile response corresponds with a tactile field in the virtual workspace, wherein the programming includes;

selecting a particular tactile field from among a plurality of tactile fields which is individually adjustable with regard to strength, shape or size prior to navigating through the virtual workspace under guidance of the programmed tactile response,

adjusting a parameter of the particular tactile field, and

mapping the adjusted particular tactile field onto the virtual workspace.

12. A method of enabling a user to navigate through a virtual workspace, said method comprising the steps of:

providing a visual representation of the virtual workspace on a display screen;

enabling a user to guide a cursor object across the display screen;

providing a tactile response to the user while guiding the cursor object; and

enabling the user to program a parameter of the tactile response prior to navigating through the virtual workspace, wherein the parameter of the tactile response that is rendered user-programmable by the system comprises a dynamic behavior of the tactile field, and wherein said dynamic behavior is programmable to have intensity of the tactile field wear down when the tactile field is repeatedly actuated.
