  • Patent number: 11334198
    Abstract: A single volume soft sensor capable of sensing real-time continuous contact and stretching. A low-cost and an easy method to fabricate such piezoresistive elastomer-based soft sensors for instant interactions is also provided. An electrical impedance tomography (EIT) technique is employed to estimate changes of resistance distribution on the sensor caused by fingertip contact. To compensate for the rebound elasticity of the elastomer and achieve real-time contact sensing, an adaptive baseline update for EIT is utilized. The baseline updates are triggered by fingertip contact and movement detections.

  • Patent number: 11199901
    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.
