    Abstract: An e-pen includes e-pen sensor electrodes (including a first and a second e-pen sensor electrode) and drive-sense circuits (DSCs) (including a first DSC and a second DSC. The first DSC drives a first e-pen signal having a first frequency via a first single line coupling to the first e-pen sensor electrode and simultaneously senses, via the first single line, the first e-pen signal. Based on e-pen/touch sensor device interaction, the first e-pen signal is coupled into at least one touch sensor electrode of the touch sensor device. The first DSC process the first e-pen signal to generate a first digital signal representative of a first electrical characteristic of the first e-pen sensor electrode.

  • Patent number: 11175734
    Abstract: A head-mountable device can be operated with devices worn on wrists, arms, hands, and/or other limbs of a user. Such devices can provide indicators that allow a head-mountable device to determine both an identity and a characteristic (e.g., position, orientation, distance, etc.) of the devices and therefore the user. The information regarding the tracking devices and/or the hands can be used to produce a virtual representation of the hands or otherwise be used to receive and interpret gestures as user input. The devices that facilitate such tracking can be worn in a variety or arrangements depending on whether the tracking is to be performed. As such, they can be compactly stored in a manner that allows them to be readily accessible for deployment.
