Abstract

One embodiment of the disclosure includes an input module. The input module includes a switch, a rotatable and translatable input member operably connected to the switch and configured to actuate the switch, and an electrical contact operably connected to the switch and in electrical communication with the input member. During operation, the electrical connection between the input member and the electrical contact is maintained during translation and rotation of the input member. The input module may be used with a variety of electronic devices and can be used by a user to provide input to those devices.

Claims

1-25. -25. (canceled)

26. A watch comprising:

an enclosure having a sidewall and an opening in the sidewall;

a crown positioned along an exterior of the sidewall;

a shaft coupled to the crown and extending through the opening;

an optical sensor positioned within the enclosure and configured to detect a rotation of the shaft; and

a tactile switch positioned within the enclosure and configured to;

detect a depressed position of the shaft when the crown is pressed inward toward the enclosure; and

bias the shaft outward toward an undepressed position.

27. The watch of claim 26, further comprising:

a display at least partially positioned within the enclosure; and

a touch sensor configured to detect a touch input received at the display.

28. The watch of claim 27, wherein the display is configured to produce graphical outputs that are configured to change in response to each of:

the rotation of the shaft;

the depressed position of the shaft; and

the touch input of the display.

29. The watch of claim 26, wherein the optical sensor is configured to detect the rotation of the shaft using reflected light.

30. The watch of claim 26, wherein:

the tactile switch includes a collapsible dome positioned at an end of the shaft; and

the collapsible dome is configured to provide a return force that biases the shaft outward toward the undepressed position.

31. The watch of claim 30, wherein:

the collapsible dome is deformed by the shaft when the crown is pressed inward toward the enclosure;

the tactile switch is configured to produce a haptic output when the collapsible dome deforms; and

the haptic output is propagated through the crown.

32. The watch of claim 26, wherein the crown and the shaft are integrally formed.

33. A watch comprising:

an enclosure having an opening;

a crown positioned along an exterior of the enclosure and configured to receive a rotation and an inward translation along an actuation direction;

a shaft coupled to the crown and extending into the opening;

a spring coupled to the crown and configured to bias the crown outward in a return direction that is opposite to the actuation direction;

an optical sensor positioned within the enclosure and configured to detect at least one of the rotation or the inward translation; and

a processing unit positioned within the enclosure and configured to control a function of the watch in response to the rotation or the inward translation.

34. The watch of claim 33, further comprising:

a tactile switch positioned at an end of the shaft and configured to detect the inward translation.

35. The watch of claim 34, wherein:

the tactile switch comprises a collapsible dome; and

the shaft causes the collapsible dome to collapse in response to the inward translation and close electrical contacts of a switch.

36. The watch of claim 33, wherein:

the opening is a first opening in a sidewall of the enclosure;

the enclosure has a second opening; and

the watch further comprises;

a display positioned at least partially within the second opening; and

a touch sensor configured to detect a touch input received at the display.

37. The watch of claim 36, wherein:

the display is configured to depict icons; and

the icons move in response to the rotation.

38. The watch of claim 33, wherein the crown defines a hollow portion configured to receive an electrical component of the watch.

39. The watch of claim 33, wherein the optical sensor is positioned proximate an end of the shaft.

40. The watch of claim 33, further comprising a shelf connected to the shaft and configured to limit an outward translation of the shaft along the return direction.

41. A watch comprising:

an enclosure having an opening;

a tactile switch assembly extending into the opening and configured to receive a rotational input and a translational input, the tactile switch assembly being biased toward an undepressed position;

a first sensor positioned within the enclosure and configured to detect the rotational input using reflected light; and

a second sensor positioned within the enclosure and configured to detect the translational input.

42. The watch of claim 41, wherein:

the tactile switch assembly comprises;

a crown positioned along an exterior of the enclosure and configured to receive the rotational input and the translational input; and

a shaft connected to the crown and extending into the opening.

43. The watch of claim 42, wherein the second sensor includes a collapsible dome positioned at an end of the shaft.

44. The watch of claim 42, wherein the reflected light is reflected off a surface of the shaft.

45. The watch of claim 41, wherein:

the watch further comprises a display positioned at least partially within the enclosure; and

the display is configured to;

display movement of a first group of graphical objects, in response to the rotational input; and

display a second group of graphical objects, in response to the translational input.
