Abstract: Methods, systems, apparatuses, and computer program products are provided herein for determining the handedness of input provided by a user via a touch interface. For instance, for each touch-based input detected, a score indicating a probability whether the touch-based input was inputted by a particular hand of the user is generated. A classification for the touch-based input is then generated based on a drift diffusion model-based technique in which inter-dependencies between a series of touch-based input are approximated. The determined classifications are aggregated and compared to threshold(s) to determine the handedness of the user. For example, if the aggregated classifications meet a first threshold, then a determination is made that touch-based input provided by a user was inputted by the user's left hand. If the aggregated classifications meet a second threshold, then a determination is made that touch-based input provided by the user was inputted by the user's right hand.

Abstract: A system may have one or more electronic devices that include user input sensors such as force sensors, touch sensors, motion sensors, and other input devices. To provide a user with output, devices may have visual output components such as displays, audio output components, and haptic output components. Haptic output components may be used to apply an apparent force in a given direction relative to a device housing surface such as a sidewall surface or other device surface. Control circuitry in a device may direct a haptic output component to produce the apparent force in a direction perpendicular to the housing surface or tangential to the housing surface. The apparent applied force may be provided as feedback while the control circuitry is directing a display in the device or in an external device to provide a user with visual content based on the user input.

Abstract: In a touch screen environment, a computer calculates an effective position and updated effective positions of simultaneous or sequential touch events by calculating average coordinates of the touch events using force measurements. The average coordinates correspond to computerized maps of the user interface and z coordinates correspond to an average force at the x and y locations. The effective positions are used to determine if the user's touches move across multiple virtual input areas having priority and non-priority relationships. By expanding a virtual input area of the map for those areas having a priority label relative to a different non-priority virtual input area, the computer effectuates appropriate functions depending on where the most recent effective position lies.

Abstract: A head-mounted device may have displays that provide images. Waveguides may be used in conveying the images to eye boxes. The waveguides may overlap lenses in a glasses frame or other head-mounted support structure. The waveguides and lenses may be transparent. This allows real-world objects to be viewed from the eye boxes. Infrared-light reflectors may overlap the lenses. Gaze tracking system light sources may supply infrared light that reflects from the infrared-light reflectors to the eye boxes to illuminate a user's eyes. Gaze tracking system cameras capture gaze tracking images of the eyes from the eye boxes to track the user's gaze. Fiducials associated with the infrared-light reflectors may be monitored using the gaze tracking system cameras. This allows components such as the gaze tracking system cameras to be calibrated.
