  "title": "Haptic feedback apparatus",
  "abstract": "Examples disclosed herein relate to providing haptic feedback. One disclosed example provides a wearable article configured to provide haptic feedback, the wearable article including a base configured to be worn on a body part, a force-applying mechanism coupled with the base, and a haptic feedback apparatus coupled with the base, the haptic feedback apparatus including a lever supported by a frame and coupled with the force-applying mechanism, the lever positioned to move relative to the frame and apply pressure on a surface of the body part when a force is applied by the force applying mechanism.",
  "claims": [
    "1. A wearable article, configured to be worn by a human and to provide haptic feedback to the human, the wearable article comprising: a base configured to be worn on a body part of the human; a force-applying mechanism coupled with the base; and a haptic feedback apparatus, for providing the haptic feedback to the human, coupled with the base at a location corresponding to a finger of the human, the haptic feedback apparatus comprising a lever supported by a frame and coupled with the force-applying mechanism, the lever positioned to pivot about the frame and apply pressure on a surface of the body part when a force is applied by the force applying mechanism.",
    "2. The wearable article of claim 1, further comprising a spring that biases the lever away from the surface of the body part.",
    "3. The wearable article of claim 1, wherein the haptic feedback apparatus comprises a thimble or ring shape configured to be worn on the finger.",
    "4. The wearable article of claim 1, wherein the lever is pivotally connected to the frame.",
    "5. The wearable article of claim 1, wherein the lever is integral with the frame.",
    "6. The wearable article of claim 5, wherein the lever and the frame comprise a molded polyurethane structure.",
    "7. The wearable article of claim 1, wherein the lever is made from a first, harder material, and further comprising a second, softer material coupled to a surface of the lever.",
    "8. The wearable article of claim 1, wherein the force-applying mechanism comprises a clutch mechanism configured to restrict articulation of an articulable joint and thereby apply a pulling force to the lever.",
    "9. A wearable article configured to be worn by a human and to provide haptic feedback to the human, the wearable article comprising: a fabric base configured to be worn on a hand of a human; a force-applying mechanism coupled with the fabric base; and a haptic feedback apparatus, for providing the haptic feedback to the human, the haptic feedback apparatus molded onto the fabric base at a location corresponding to a finger of the human, the haptic feedback apparatus comprising a lever supported by a frame and coupled with the force-applying mechanism, the lever positioned to pivot about the frame and apply pressure on a surface of the body part when a force is applied by the force-applying mechanism.",
    "10. The wearable article of claim 9, wherein the lever is pivotally connected to the frame.",
    "11. The wearable article of claim 9, wherein the lever is integral with the frame.",
    "12. The wearable article of claim 9, further comprising a second haptic feedback apparatus molded onto the fabric base at a different location than the haptic feedback apparatus."

  "description_excerpt": "Virtual reality display systems immerse a user in virtual imagery occupying an entire field of view. Augmented reality or mixed reality display systems display virtual objects superimposed with real-world backgrounds, such as via a see-through display. In either case, visual and auditory aspects of a virtual experience may be represented in a lifelike manner.\n\nThis Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.\n\nExamples are disclosed that relate to wearable articles configured to provide haptic feedback. One disclosed example provides a wearable article comprising a base configured to be worn on a body part, a force-applying mechanism coupled with the base, and a haptic feedback apparatus coupled with the base, the haptic feedback apparatus comprising a lever supported by a frame and coupled with the force-applying mechanism, the lever positioned to move relative to the frame and apply pressure on a surface of the body part when a force is applied by the force applying mechanism.",
