    Abstract: The disclosed technologies address technical problems, including improving human-computer interaction, by augmenting the functionality provided by non-digital objects using a digital glove. To provide this functionality, a machine learning model is trained using sensor data generated by sensors in a digital glove and data generated by a user input device while the digital glove is utilized to manipulate an object like a user input device. Once trained, the machine learning model can take sensor data generated by a digital glove while manipulating a non-digital object and generate virtual user input device data that can be utilized to control a host computer. A digital glove can also be utilized to perform selection operations using non-digital objects when pressure data generated by one or more of the pressure sensors in the digital glove indicates that pressure was exerted at a finger of the digital glove in excess of a threshold value.

    Abstract: Examples are disclosed that relate to electrostatic clutching mechanisms that may be used for tactile feedback. One example provides a motion-restricting apparatus comprising a wearable base, and an electrostatic clutching mechanism coupled to the base, the electrostatic clutching mechanism comprising a base electrode, a plurality of individually-controllable opposing electrodes arranged at different locations across the base electrode and overlapping the base electrode, and one or more electrically insulating structures configured to electrically insulate the base electrode from the plurality of opposing electrodes. The motion-restricting apparatus further comprises a controller electrically coupled to the base electrode and to each of the opposing electrodes and configured to individually control a voltage applied to each opposing electrode relative to a voltage of the base electrode to control an electrostatic force between the base electrode and each opposing electrode.
