the control device:

receives, from the switch upon the switch moving from the un-pressed position to the pressed position, a switch signal comprising the closed signal; and

directs the head-mounted display to animate, at a virtual location in a virtual space corresponding to a real-world location of the key assembly and in real-time relative to the switch moving from the un-pressed position to the pressed position, a visual representation of a fingertip moving a visual representation of the key assembly from the un-pressed position to the pressed position.

10. The virtual reality interface system of claim 9 , wherein the touch sensor comprises a capacitive touch sensor.

11. The virtual reality interface system of claim 9 , wherein the key cap further comprises an interface surface that is coupled to the touch sensor.

13. The virtual reality interface system of claim 11 , wherein the interface surface defines a concave depression that is adapted to receive a fingertip of a human finger.

14. The virtual reality interface system of claim 11 , wherein:

when the touch sensor senses a touch event, the touch sensor sends a touch signal to the control device; and

when the touch sensor senses an absence of touch, the touch sensor sends a control signal to the control device; and

the control device receives, from the touch sensor, a touch sensor signal comprising at least one of:

the touch signal; or

the control signal.

15. The virtual reality interface system of claim 14 , wherein:

the keyboard comprises at least one additional key assembly that is communicatively coupled to the control device;

the control device receives an additional signal from the additional key assembly; and

at least one of the visual representation of the key assembly and the visual representation of the fingertip is further based on the additional signal.

16. The virtual reality interface system of claim 14 , wherein the visual representation of the key assembly is in the pressed position when the switch signal includes the closed signal.

17. The virtual reality interface system of claim 16 , wherein:

the visual representation of the fingertip is in contact with a visual representation of the interface surface of the key cap when the touch sensor signal includes the touch signal; and

the visual representation of the fingertip is disconnected from the visual representation of the key cap when the touch sensor signal includes the control signal.

18. A method comprising:

sensing a touch event via a touch sensor included in a key cap included in a key assembly of a virtual reality interface system;

determining, while the touch sensor senses the touch event, that a switch included in the key assembly has moved from an un-pressed position to a pressed position; and

directing, while the touch sensor senses the touch event, a head-mounted display included in the virtual reality interface system to animate, at a virtual location in a virtual space corresponding to a real-world location of the key assembly and in real-time relative to the switch moving from the un-pressed position, based on sensing the touch event and determining that the switch has moved from the un-pressed position to the pressed position, a visual representation of a fingertip moving a visual representation of the key assembly from the un-pressed position to the pressed position.

19. The method of claim 18 , further comprising:
