The one or more composite bioelectrodes may include (1) a circuitry-interfacing side with a mechanical or electrical property having a first predetermined configuration and (2) a user-interfacing side with the mechanical or electrical property having a second predetermined configuration. Various other composite bioelectrodes, systems, and methods are also disclosed.

Abstract: A user-input device includes a user-actuatable trigger configured to pivot about a trigger axis, a rack gear interfacing with the user-actuatable trigger, a force-feedback motor including a drive gear interfacing with the rack gear, and a posture sensor configured to determine a posture of the user-actuatable trigger about the trigger axis. The force-feedback motor is configured to drive the rack gear based on a force-feedback signal.

Abstract: A user-input device includes a user-actuatable trigger configured to pivot about a trigger axis, a posture sensor configured to determine a posture of the user-actuatable trigger about the trigger axis, a force sensor configured to determine an actuation force applied to the user-actuatable trigger, and a force-feedback motor operatively coupled to the user-actuatable trigger. The force-feedback motor is configured to activate based on a force-feedback signal and adjust a user-perceived state of the user-actuatable trigger.

Abstract: Examples are disclosed that relate to handheld input devices having pressable user input mechanisms configured to move in a manner that adapts to different hands. One disclosed example provides a handheld input device comprising a body configured to be held by a hand such that one or more fingers of the hand are curved at least partially toward a palm of the hand, a pressable user input mechanism positioned on the body at such a location as to be in contact with a palm-side surface of a finger when the handheld input device is held, and a hinge coupling between the body and the pressable user input mechanism, the hinge coupling comprising an axis of rotation that varies based upon a characteristic of force applied to the pressable user input mechanism.

Abstract: Methods, systems, apparatuses, and computer program products are provided for a user input device, such as a game controller. The user input device includes a finger depressible trigger button, a trigger travel path adjustment assembly that resides in an internal cavity of a housing of the user input device, and a finger switch configured to be switched between a plurality of selectable positions in real-time (e.g., during game play). A first selectable position of the finger switch enables the trigger button to be depressed a first distance. A second selectable position of the finger switch enables the trigger button to be depressed a second distance that is greater than the first distance.

Abstract: Methods, systems, apparatuses, and devices are provided for an electrostatic rotary clutch. The clutch comprises electrically-conductive housing plates fixed into position in grooves within a housing of the clutch. The clutch also comprises rotor plates that are fixed onto a shaft. The shaft is positioned within the housing such that each rotor plate is adjacently positioned next to each housing plate, thereby forming a plurality of electrically-conductive plate pairs. To produce a torque resistance on the shaft, a voltage differential is applied between the housing and rotor plates, which causes an electrostatic adhesion between the housing and rotor plate in each electrically-conductive plate pair. Alternatively, the housing and rotor plates are not fixed into position, enabling a greater number of housing and rotor plates within the housing and increasing the torque resistance produced on the shaft when applying the voltage differential.

Abstract: A game controller includes a trigger-activation sensor, a sensor-activation feature, and a trigger-retention feature. The sensor-activation feature is moveable relative to the trigger-activation sensor. The trigger-activation sensor outputs a control signal based on a relative position of the sensor-activation feature and the trigger-activation sensor. The trigger-retention feature is configured to removably affix a selected removable trigger accessory to the game controller. The selected removable trigger accessory is one of a plurality of differently configured removable trigger accessories removably affixable to the game controller. The selected removable trigger accessory is configured to change the relative position of the sensor-activation feature and the trigger-activation sensor based on finger manipulation of the selected removable trigger accessory when the selected removable trigger accessory is removably affixed to the game controller.

Abstract: A user input device is provided that includes a button-based control mechanism. The button-based control mechanism includes a button, the button including a user-depressible button top and a button stem, and a button depression guide disposed within an internal cavity of the user input device that engages with the button stem to cause the button to move from a default position and along a substantially arc-shaped path when pressure is applied to the button top. The substantially arc-shaped path may be around an axis of rotation that is external to the user input device. The button-based control mechanism further includes a button biasing mechanism disposed within the internal cavity that returns the button to the default position when the pressure is removed from the button top and at least one sensor that detects actuation of the button responsive to the movement of the button away from the default position.

Abstract: An accessory apparatus includes a housing, an apparatus connector, a plurality of auxiliary accessory interfaces, and an internal microcontroller. The connection connector is configured to mate with a corresponding accessory connector of a physical controller to electrically connect the internal microcontroller to the physical controller. Each auxiliary accessory connector is configured to enable a separate auxiliary user input device to operatively connect to the accessory apparatus and electrically connect with the internal microcontroller. The internal microcontroller is configured to: (1) receive an input control signal from an auxiliary user input device operatively connected to an auxiliary accessory connector of the plurality of auxiliary accessory connectors, (2) map the input control signal to a mapped control signal corresponding to a physical control of the physical controller, and (3) send the mapped control signal to the physical controller via the apparatus connector.
