Abstract
A user-worn device (100) comprising an ultrasonic transducer configured for contacting a first body-part (116), e.g., a wrist, of a user and a touch-device (250) comprising an ultrasonic transducer (201) configured for contacting a second body-part (112), e.g., a finger, of the user are provided. The ultrasonic transducer comprised in the user-worn device (100) is further configured for transmitting data between the user-worn device (100) and the touch-device (250) encoded in ultrasound (121) via the second body-part (112). The user-worn device (100) is operative to receive, from the touch-device (250), an indication identifying data to be transmitted to the touch-device, select data for transmission to the touch-device (250) based on the received indication, and transmit the selected data to the touch-device (250). The touch-device (250) is operative to transmit, to the user-worn device (100), an indication identifying data to be transmitted to the touch-device (250), and receive the data from the user-worn device (100).
