Technical Field

The present invention relates to input/output devices for computer-based devices. More particularly, the present invention relates to haptic controllers.

Background

At some electronic devices may be provided with tactile feedback referred to as "tactile haptic feedback" or "tactile haptic effects" and may include, for example, vibrations, textures, temperature changes, etc. kinesthetic feedback referred to as "kinesthetic haptic feedback" or "kinesthetic haptic effects" and may include, for example, active and resistive feedback.

However, only when the trigger is moved in the opposite direction, e.g., when the trigger is moved away from the user's finger, the user's finger does not feel the haptic effect because such movement causes the trigger to be inaccessible to the user's finger for a short period of time.

Fig. 2 illustrates a controller 172 according to an embodiment of the invention.

The controller 172 may include various components including a housing 173, communication interfaces 174 and , or more triggers 175, haptic actuators (not shown for clarity), joysticks, buttons, touch pads, Light Emitting Diodes (LEDs), LCD displays, and the like.

The housing 173 is shaped to readily accommodate a user's grip on the controller 172.

Communication interface 174 may provide a wired connection, such as a USB cable port, to computer 100. Alternatively, the communication interface 174 may provide a wireless connection, such as Bluetooth, to the computer 100. Appropriate interface cards, electronic boards, components, etc. are also provided. Power for the controller 172 may be provided by a wired connection or alternatively by a rechargeable battery, a dedicated power cord, or the like. The communication interface 174 receives the haptic effect signal from the computer 100 and sends the haptic effect signal to the haptic actuator through the electrical coupling, the haptic actuator generating the haptic effect based on the haptic effect signal. When controller 172 includes an internal microprocessor, communication interface 174 may send haptic signals to the microprocessor, which may process the haptic signals prior to sending haptic effect signals to the haptic actuators.

Typically, the trigger 175 is mechanically coupled to the housing 173. In some embodiments, the trigger 175 may be a linear trigger, i.e., a trigger that moves back and forth in a linear motion, while in other embodiments, the trigger 175 is a rotary trigger, i.e., a trigger that rotates about an axis of rotation.

Fig. 3 illustrates a cross-sectional view of a trigger 175 for the controller 172, according to an embodiment of the present invention.

In this embodiment, the trigger 175 includes a rotational coupling 179 at an upper end (proximal end), a face 176, and an end effector 177 extending from a lower end (distal end). Rotational coupling 179 connects trigger 175 to housing 173 and allows trigger 175 to rotate about an axis such as the Z-axis shown in fig. 3. Rotational coupling 179 may be a hinge, flexure, or the like. Portion 182 of face 176 is configured to engage the surface of a finger during generation of a haptic effect. Similarly, the portion 184 of the end effector 177 is configured to engage a different surface of the finger during generation of the haptic effect. These engagements are shown in more detail in the embodiment shown in fig. 4 and 5.

In some embodiments, the end effector 177 is an arcuate surface opposite the face 176, the arcuate surface having an edge 178 that defines a gap 180 between the end effector 177 and the face 176, through which gap 180 a finger passes, as shown in FIG. 3, the gap 180 is disposed in the X-Z plane moving the finger through the gap 180 into engagement with the trigger 175 in the Y direction or moving the finger into engagement with the trigger 175 in the Z direction.

A haptic actuator (not shown for clarity) is mounted to housing 173, and the haptic actuator is mechanically coupled to trigger 175 and electrically coupled to communication interface 174. In certain embodiments, the haptic actuator generates the haptic effect by applying a torque to the trigger 175 along the Z-axis through the rotational coupling 179, thereby causing the trigger 175 to move in the X-Y plane. In this embodiment, the portion 182 of the face 176 and the portion 184 of the end effector 177 are perpendicular to the X-Y plane. In other embodiments, portions 182 and 184 may not be perpendicular to the X-Y plane and the resulting movement of trigger 175 may be in a different plane.

In embodiments, torque may be applied to the trigger 175 by a linear actuator attached to (e.g., pinned to, etc.) the trigger 175 such that a moment arm is created between the attachment point and the axis of rotation of the rotary coupling 179. the periodic movement of the linear actuator creates a torque on the trigger 175 that causes the trigger 175 to move periodically in the X-Y plane.

A spring (not shown for clarity) may be coupled to the trigger 175 to return the trigger 175 to a nominal position when no force is applied by the user's finger. Alternatively, the haptic actuator may return the trigger 175 to the nominal position when no force is applied by the user's finger, or a spring may not be required to return the trigger 175 to the nominal position when no force is applied by the user's finger. A position sensor (not shown for clarity) is mounted to the housing 173 and is configured to detect the position of the trigger 175. Alternatively, the position sensor may be incorporated inside the haptic actuator.

However, when the trigger is moved back toward the controller, the finger "floats," i.e., the finger is not in contact with the trigger, and this portion of the haptic effect is not transferred to the user.

In sharp contrast, controller 172 advantageously presents a haptic effect that not only pushes the user's finger (via face 176), but also pulls the user's finger (via end effector 177), allowing the user to feel all the haptic feedback in both directions.

Fig. 4A shows a cross-sectional view of the trigger 175 shown in fig. 3, while fig. 4B shows a cross-sectional view of the trigger 175 shown in fig. 3 in a second position.

In FIG. 4A, during the generation of the haptic effect, specifically, when the trigger 175 is moved in the th direction (e.g., the positive X direction) away from the housing 173, the portion 182 of the face 176 has engaged the surface 192 of the finger 190. in this embodiment, there is a gap 186 between the portion 184 of the end effector 177 and the finger 190.

Similarly, in FIG. 4B, during generation of the haptic effect, when the trigger 175 is moved in a second direction (e.g., the negative X direction) toward the housing 173 and opposite the th direction, the portion 184 of the end effector 177 has engaged the surface 194 of the finger 190.

In the embodiment shown in fig. 4A and 4B, during haptic effect generation, portion 182 of facet 176 periodically engages surface 192 of finger 190 and portion 184 of end effector 177 periodically engages surface 194 of finger 190. In other words, as trigger 175 moves back and forth during the generation of a haptic effect, portion 182 of face 176 and portion 184 of end effector 177 alternately engage finger 190. The engagement period is based on the frequency of the haptic effect signal.

As described above, the finger 190 may fit into the space between the face 176 and the end effector 177 without leaving the gap 186 or the gap 188. In this case, portion 182 of face 176 continuously engages surface 192 of finger 190, and portion 184 of end effector 177 continuously engages surface 194 of finger 190. Advantageously, various embodiments of the present invention provide an adjustable trigger that continuously engages the finger 190 during the generation of the haptic effect.

FIG. 5 illustrates a cross-sectional view of the trigger 175 illustrated in FIG. 3 in accordance with another embodiment of the invention insert member 187 may be attached to face 176 and end effector 177 to eliminate gaps 186 and 188. insert member 187 may be made of hard or soft plastic or rubber or the like.

FIG. 6 illustrates a cross-sectional view of a trigger 275 according to another embodiment of the invention the trigger 275 includes a face 276 and an adjustable end effector 277 to eliminate the gap 186 and the gap 188. in this embodiment, the trigger 275 includes a rotational coupling 279, the rotational coupling 279 allowing the adjustable end effector 277 to rotate to different positions and then lock into place, thereby increasing or decreasing the width of the gap 180 to accommodate different finger sizes. in another embodiment, the trigger 275 includes a flexible or deformable end effector 277 instead of the rotational coupling 279 to accommodate different finger sizes.

FIG. 7 illustrates a cross-sectional view of a trigger 375 according to another embodiment of the invention trigger 375 includes an end effector 377 and a face 376 to eliminate gap 186 and gap 188. in this embodiment, face 376 includes an adjustable portion 385 that eliminates gap 186 and gap 188 to accommodate different finger sizes. in this embodiment, adjustable portion 385 continuously engages surface 192 of finger 190 and end effector 377 continuously engages surface 194 of finger 190.

In embodiments, the end effector is a resilient or non-resilient strip (band) or band (strip) attached to the trigger 175 that couples the finger 190 to the trigger 175. in another embodiments, the end effector does not protrude from the distal end of the trigger 175. instead, the end effector is a viscous substance, such as an adhesive, that is applied at least to the distal end of the face 176 and couples the finger 190 to the trigger 175. in another embodiments, the end effector is a magnet embedded in the face 176. the magnet may be recessed from the surface of the face 176, flush with the surface of the face 176, or protrude from the surface of the face 176. magnetic gloves or finger gloves, rings, etc. having opposite polarity and worn over the finger 190 couple the finger 190 to the trigger 175. in another embodiments, the end effector is a hook-and-loop fastener is applied at least to the distal end of the face 176 and couples the finger 190 to the trigger 175 using gloves or finger gloves that also incorporate a hook-loop fastener.
