Abstract

In various example embodiments, a system and method for simulating touch in a virtual environment is disclosed. In one example embodiment, a method includes receiving an indicator of a touch in a virtual environment, the indicator including a physical touch location and a texture of the touch, generating one or more commands that simulate the texture of the touch at the physical touch location by stimulating one or more micro-touch simulators in an array of micro-touch simulators according to the texture of the touch at the physical touch location, and executing the one or more commands at the physical touch interface to simulate the touch at the physical touch location for the user.

Claims

1. A system comprising:

an array of micro-touch simulators configured in an article of apparel, respective micro-touch simulators comprising one of a charged microsphere and a magnetic cylinder, that is movable to contact the skin of a user that is wearing the article;

a virtual module to receive an indicator of a virtual touch in a virtual environment, the indicator indicating an area of a physical touch and a texture of the physical touch to be simulated in the area;

a command module to generate a command that simulates the texture in the area by applying respective electric fields to the array of micro-touch simulators;

an execution module to execute the command causing the plurality of micro-touch simulators to touch the user in the area and according to the texture.

2. The system of claim 1, wherein the indicator further includes a force of the touch, the command to stimulate the micro-touch simulators according to the force.

3. The system of claim 1, the array further comprising insulators between the micro-spheres allowing the system to effectuate each micro-sphere independently.

4. The system of claim 1, wherein the location indicates a part of the body of the user and the physical touch location comprises two touches at different sides of the part of the body of the user to simulate a pinching experience at the physical touch location.

5. The system of claim 1, wherein the touch moves from the physical touch location to another location, the one or more commands to stimulate a sequence of portions of the array of micro-touch simulators to simulate the dynamic touch via the physical touch interface.

6. The system of claim 1, wherein the operations further comprise interrupting execution of the one or more commands in response to the system determining that a user movement disengaged the touch in the virtual environment.

7. The system of claim 1, wherein the touch comprises the user donning an article of clothing, the one or more commands simulating a texture of the clothing, the location of the touch comprising one or more locations where the article of clothing touches the user in the virtual environment.

8. The system of claim 1, wherein the touch comprises the user touching a virtual item representing a physical item that is available for purchase.

9. A computer-implemented method comprising:

receiving an indicator of a touch in a virtual environment, the indicator including a physical touch area and a texture of the physical touch area;

generating one or more commands that simulate the texture of the touch in the physical touch area by applying a field to one or more micro-touch simulators in an array of micro-touch simulators, respective micro-touch simulators comprising one of a charged microsphere and a magnetic cylinder, the field moving the micro-touch simulators according to the texture of the touch in the area of the physical touch location, the micro-touch simulators operating as part of a physical touch interface for a user of the virtual environment;

executing the one or more commands at the physical touch interface to simulate the touch in the touch area.

10. The method of claim 9, wherein the indicator further includes a magnitude of the touch, the one or more commands to simulate the touch magnitude.

11. The method of claim 9, wherein the physical touch interface for the user comprises a body suit that includes the micro-touch simulators.

12. The method of claim 9, further the array further comprises insulators between the micro-touch simulators allowing independent activation of each of the micro-touch simulators.

13. The method of claim 9, wherein the physical area indicates a part of the body of the user and the physical touch area includes an area of the array of micro-touch simulators that is around the part of the body of the user to simulate a grabbing experience in the physical touch.

14. The method of claim 9, wherein the touch comprises a dynamic touch, the one or more commands to stimulate a sequence of portions of the array of micro-touch simulators to simulate the dynamic touch via the physical touch interface.

15. The method of claim 9, further comprising interrupting execution of the one or more commands in response to a user movement that disengages the touch in the virtual environment.

16. A machine-readable memory storing executable instructions, which, when executed by at least one processor of a machine, cause the machine to perform operations comprising:

receiving an indicator of a touch in a virtual environment, the indicator including a physical touch area and a texture of the touch area;

generating one or more commands that simulate the texture of the touch at the physical touch area by stimulating one or more micro-touch simulators in an array of micro-touch simulators at the physical touch area, the micro-touch simulators operating as part of a physical touch interface for a user of the virtual environment, each micro-touch simulator comprising one of a charged microsphere being movable using an electric field and a magnetic cylinder being movable using a magnetic field;

executing the one or more commands at the physical touch interface to simulate the touch at the physical touch area.

17. The machine-readable medium of claim 16, wherein the method further comprises varying respective magnetic field magnitudes for the micro-touch simulators located within the area according to a force of the physical touch.

18. The machine-readable medium of claim 16, wherein the touch comprises a dynamic touch, the one or more commands to stimulate a sequence of portions of the array of micro-touch simulators to simulate the dynamic touch via the physical touch interface.
