TECHNICAL FIELD

This patent application is directed to handheld controllers and, more specifically, to virtual reality handheld controllers.

BACKGROUND

In a virtual reality system, a user wears a head-mounted display that presents a selected virtual reality (VR) environment in front of the user's eyes. In some VR systems, a user can manipulate items in the virtual environment with handheld controllers. The controllers include tracking patterns comprised of a pattern of lights, for example. The system monitors the movement of the tracking patterns with a tracking camera and reproduces the user's hand movements in the virtual environment. However, buttons traditionally used on game controllers, for example, do not typically detect detailed hand movements. For example, individual finger movements and gestures, as well as hand movements relative to the controller, are not captured with traditional button configurations.

The following description provides specific details for a thorough understanding and enabling description of these examples. One skilled in the relevant art will understand, however, that the techniques discussed herein may be practiced without many of these details. Likewise, one skilled in the relevant art will also understand that the technology can include many other features not described in detail herein. Additionally, some well-known structures or functions may not be shown or described in detail below so as to avoid unnecessarily obscuring the relevant description.

The terminology used below is to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of some specific examples of the embodiments. Indeed, some terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this section.

FIG. 1 illustrates a pair of handheld controllers 100 according to a representative embodiment. The pair of handheld controllers 100 includes a right-hand controller 102 and a left-hand controller 104. The primary structure of the right-hand controller 102 and the left-hand controller 104 when held adjacent to each other in a similar orientation, as illustrated, are substantially symmetric with respect to each other. Both the controllers 102/104 are described herein with respect to the right-hand controller 102, as both controllers include the same or similar features, albeit in mirror image. The right-hand controller 102 includes a main body 106 and a handle portion 108 extending from the main body 106. In some embodiments, a surrounding ring portion 110 extends from the main body 106. The controllers 102/104 can be part of a VR system 10, such as the Rift™ available from Oculus™.

As shown in FIG. 2, the right-hand controller 102 includes a thumbstick 112, a trigger button 114 and a third-finger button 116. The main body 106 includes a thumb surface 118 from which the thumbstick 112 extends. The main body 106 may also include one or more buttons 120 and 122 positioned on the thumb surface 118. In some embodiments, the thumb surface 118 is a substantially planar surface. The handle portion 108 extends from the main body 106 on a side generally opposite the trigger button 114. The main body 106 and the handle portion 108 are ergonomically contoured such that a user's hand 5 can comfortably grasp the handheld controller 102 as illustrated. When the controller 102 is grasped, the user's thumb 7 (i.e., the first finger) is comfortably positionable above the main body 106 with the thumb 7 engaging on the thumbstick 112. The user's second or index finger 9 is positioned on the trigger button 114. The user's third or middle finger 11 operates the third-finger button 116. The third-finger button 116 is operative to detect whether the user is grasping the handle portion 108 with his or her third-finger 11. In some embodiments, the third-finger button 116 can detect various degrees of deflection corresponding to the force or pressure of a user's grip on the handle portion 108.

In some embodiments, the third-finger button 116 is active depending on the context of an associated virtual environment or game. In other embodiments, the third-finger button 116 is activated mechanically or by another sensor. One embodiment could include a palm sensor (e.g., analogous to a pistol grip safety or grip switch), such that when the palm sensor detects the user's hand, and the third-finger button 116 is released, an output signal indicates an “open-hand gesture.”

In some embodiments, the handle portion 108 can include one or more detection sensors 125 positioned to detect the presence of the user's palm or a portion of a finger, indicating that the user is holding the handle portion 108, indicating how the user is holding the handle portion, or how the user is moving his or her hand relative to the handle portion. For example, the detection sensor 125 can be a capacitive touch sensor on the handle portion, such as adjacent to the third finger button 116 or in a position for engagement by the user's fourth or fifth finger when grasping the handle. A detection sensor 125 can be positioned to be engaged by a portion of the user's second finger (i.e., index finger) or third finger (i.e., middle finger) that is on the handle portion 108 adjacent to the trigger button 114 or the third-finger button 116, indicating the presence of the user's fingers on the handle portion 108 even if the associated finger has been lifted off of the trigger button 114 or the third finger button 116. Detection sensors 125 can be provided on the handle portions corresponding to the position of all of the user's fingers grasping the handle.

In one embodiment, one or more of the detection sensors 125 are proximity sensors configured to detect the spatial location of the user's fingers or hand relative to the handle portion 108. For example, the proximity sensor 125 could be used to detect the presence of the user's finger and the separation distance between the respective finger and the surfaced of the handle portion 108. The proximity sensors 125 can be configured to allow detection of movement of the user's fingers or other portions of the user's hand relative to the handle portion 108. The detected separation distance and/or movement can be used in connection with signals, commands, or other control signals related to the hand shape or position of the user's hand or fingers relative to the handle portion 108.

In some embodiments, the handle portion 108 can include a combination of pressure sensors, capacitive touch sensors, and/or proximity sensors that provide signals to the VR system 10, for example, to initiate a command or to replicate a hand configuration in a corresponding apparition or avatar.

When the third-finger button 116 is depressed, the system registers that the user's hand is closed or grasped around the handle portion 108. When the third-finger button 116 is not depressed, the system can indicate an open hand gesture. The presence of a gesture can be a signal to the VR system 10 to initiate a command or to include the gesture in a corresponding apparition or avatar. The third-finger button 116 allows a user to maintain a grip on the handle portion 108 while still being able to provide hand grip inputs to the VR system. In another embodiment, the third button on the handle is positioned for engagement by the user's ring or fourth finger or the pinkie or fifth finger, or a combination of the third, fourth and/or fifth fingers. In some embodiments, the thumbstick 112, the trigger button 114, the thumb surface 118, and the buttons 120 and 122 can be configured to detect other hand and finger gestures as explained in U.S. patent application Ser. No. 14/939,470, titled “METHOD AND APPARATUS FOR DETECTING HAND GESTURES WITH A HANDHELD CONTROLLER,” filed Nov. 12, 2015, and U.S. patent application Ser. No. 14/975,049, titled HANDHELD CONTROLLER WITH ACTIVATION SENSORS, filed Dec. 18, 2015, all of which are hereby incorporated by reference in their entireties.

With reference to FIG. 3, the handle portion 108 includes a palm side 124, which confronts the palm of the user's hand 5, and a finger side 126 opposite the palm side 124 and generally confronts the fingers, such as the third-finger 11, of the user's hand 5. Accordingly, the third-finger button 116 is disposed on the finger side 126 of the handle portion 108. As shown in FIG. 4, the third-finger button 116 includes an arm 128 rotatably coupled to the main body 106 via a pivot shaft 130 extending along an axis A. With further reference to FIG. 5, the pivot shaft 130 is mounted at an angle with respect to the main body 106 in clevis arms 132 and 134 extending from the main body 106. In some embodiments, a torsion spring 136 is positioned about the pivot shaft 130 to return the arm 128 to the extended position and to provide tactile feedback to the user's third-finger 11 (see FIG. 2) in the form of a resistive force.

As shown in FIG. 6, the third-finger button 116 includes a detection feature, such as a magnet or other detectable member. In the illustrated embodiment, a magnet 140 is mounted on arm 128. A sensor 142 is positioned inside the handle adjacent the magnet 140. In some embodiments, the sensor 142 is a Hall effect sensor. A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field. Thus, as the magnet 140 moves closer to the sensor 142, the output voltage varies. Accordingly, the third-finger button 116 is an analog button in that it can detect various degrees of deflection corresponding to the force of a user's grip on the handle portion 108 and output a signal corresponding to movement of the third-finger button 116. In some embodiments, the magnet 140 and the Hall effect sensor 142 may be replaced by an on/off switch such as a miniature snap-action switch, for example. In some embodiments, movement of the third-finger button 116 can be detected with an inductive proximity sensor or other suitable type of proximity sensor. In some embodiments, the detection feature for use with a proximity sensor can be a location (e.g., target location) on the third-finger button 116.

FIG. 7 illustrates a handheld controller 202 according to a representative embodiment. The handheld controller 202 comprises a main body 206, a trigger button 210 positioned on the main body 206, and a handle portion 208 extending from the main body 206 on the side opposite the trigger button 210. The handle portion 208 has a palm side 224 and a finger side 226. A first pressure sensitive sheet or pad 214 is positioned on the palm side 224 of the handle portion 208 and a second pressure sensitive sheet or pad 216 is positioned on the finger side 226. The pressure sensitive pads 214/216 are operative to detect compression of the pads caused by a user's fingers and/or palm, thereby registering the presence and/or strength of a user's grip around the handle portion 208. In some embodiments, the handle portion 208 only includes one or other of the first and second pressure sensitive pads 214/216.
