Abstract: A method generates synchronized auditory and haptic feedback for artificial-reality environments. The method includes performing a simulation of a user interaction with a virtual object in an artificial-reality environment. The user interaction (i) traverses a surface of the virtual object (e.g., running a finger over a textured surface), and (ii) includes a set of contact events (e.g., a sparse set of events). The method also includes estimating a trajectory of the user interaction with the virtual object based on the set of contact events. The method also includes determining a surface profile associated with the surface of the virtual object, generating an excitation force profile according to (i) the estimated trajectory and (ii) the surface profile, and rendering, based on the excitation force profile, audio and synchronized haptic feedback for the user interaction.

Abstract: A detection system has an interface including a substrate supporting a conductive coating. Electrodes are provided to the substrate. A multiplexer provides current to the electrodes. A demultiplexer receives voltages from electrodes and provides corresponding signals to a controller. The controller receives these signals and determines therefrom an operation performed in connection with the interface by applying an algorithmic approach. Static interaction is recognizable, and machine learning can be used for gesture recognition and/or identification of other interaction types. The technology can be used in a broad array of applications, e.g., where it is desirable to sense interactions with a defined region such as, for example, in the case of touches, gestures, hovers, and/or the like.

Abstract: An electric field (e-field) touchscreen is described. A continuous stream of digital signal data that represents e-field signal deviations is received from multiple receive electrodes. The stream of digital signal data is processed using a machine learning model to determine a touch event and a location on a display screen of the touchscreen. The touch event is processed. The e-field touchscreen may determine whether a non-normal event may be occurring causing noise in the digital signal data. If so, the received stream of digital signal data is processed through a low-pass filter and processed through an absolute value average baseline filter. A difference between the filtered data is determined to generate a filtered stream of digital signal data and is processed using the machine learning model determine a touch event and a location on a display screen of the touch event. The touch event is processed.

Abstract: A device for motion sickness reduction, directional indication, and neural rehabilitation that provides three modes of operation. The device operates by providing haptic feedback using transducers that convert electrical signals to a tactile sensation such as pressure, vibration, electrical stimulation, temperature, or airflow.
