Abstract: A head-wearable audio device has a motion sensor that outputs motion parameter values based on a detected motion gesture. A gesture type is recognized by comparing the motion parameter values and per-user per-gesture-type recognition parameter values. An action is selected based on the selected gesture type and is executed by the head-wearable audio device or an application in a remote computing device. The head-wearable audio device may also include a capacitive touch sensor that detects capacitive touch events and outputs capacitive touch parameter values. A gesture type may be recognized by comparing both of detected motion parameter values and detected capacitive touch parameter values with per-user per-gesture-type recognition parameter values. The per-user per-gesture-type recognition parameter values are improved over time using machine learning and/or automated logic based on historical detected motion or capacitive touch parameters and corresponding selected gestures, or user profile data.

Abstract: Examples are disclosed relating to providing haptic output to a stylus. In one example, rotational position data indicating a rotational position of the stylus about a longitudinal axis of the body of the stylus is received. Travel direction data indicating a direction of travel of a tip of the stylus relative to a touch-sensitive screen of a computing device is also received. Using at least the rotational position data and the travel direction data, one or more characteristics of a drive signal are determined. The drive signal is then transmitted to a haptic feedback mechanism within the body of the stylus to generate haptic output at the body.

Abstract: A method is presented for providing haptic feedback through a touch-sensitive input device configured to provide input to a touch-sensitive computing device. The method comprises determining a haptic perception factor based on a set of computing device inputs received from sensors of the touch-sensitive computing device, the computing device inputs including at least a posture of the touch-sensitive computing device. A haptic response profile is determined based on the haptic perception factor. Haptic devices of the touch-sensitive input device are actuated based on the determined haptic response profile. Responsive to determining a change in the haptic perception factor based on a change in the posture of the touch-sensitive computing device the haptic response profile is then adjusted based on the changed haptic perception factor. The haptic devices of the touch-sensitive input device are then actuated based on the adjusted haptic response profile.

Abstract: Examples are disclosed relating to arming and managing power consumption of a haptic feedback component in a stylus prior to actuating the haptic feedback component to produce haptic output. In one example, at least on condition of detecting a first user interaction with the stylus, power is transmitted for at least a first time period to a haptic circuit communicatively coupled to the haptic feedback component. At least on condition of determining that the first time period expires, it is determined if a second user interaction with the stylus is detected. If the second user interaction is detected, the stylus continues transmitting power to the haptic circuit. If the second user interaction is not detected, the stylus ceases transmitting power to the haptic circuit.

Abstract: Examples are disclosed relating to providing haptic feedback in a stylus while the stylus crosses a gap between two displays. In one example, a method comprises detecting one or more haptic triggering criteria, and at least on condition of detecting the one or more haptic triggering criteria, actuating the haptic feedback component to produce haptic output. Using a width of the gap between the displays, a stylus velocity, and a stylus direction, a crossing time for the stylus tip to cross the gap is calculated. At a first time after actuating the haptic feedback component, the method determines that the stylus tip crosses an inside edge of one of the displays. At least on condition of determining that the tip of the stylus crosses an inside edge of a display, the method continues to actuate the haptic feedback component for the crossing time.

Abstract: An electronic device detects a user presence in a first distance range from a user detection sensor of an electronic device. The electronic device communicates with multiple input components, setting the electronic device to a first device state based on detecting a user presence in the first distance range. The first device state applies a scanning rate to a first input component. The electronic device also detects a user presence in a second distance range from the user detection sensor of the electronic device while the electronic device is in the first device state. The electronic device sets the electronic device to a second device state, based on detecting a user presence in the second distance range while the electronic device is in the first device state. The second device state applies a different scanning rate to the first input component than in the first device state.
