Patent attributes
Examples are disclosed that relate to attributing touch events on a touch-sensitive computing device to a user who performed the touch event. One example provides a computing system, comprising a touch sensor, a communication subsystem comprising a first communication mechanism integrated with the touch sensor, the first communication mechanism configured to communicate with a portable device over a first communication channel via a body-transmissible signal upon detection of a touch input, and also comprising a second communication mechanism configured to communicate with the portable device via a second communication channel. The computing device further comprises instructions executable to detect a touch input via the touch sensor, communicate information to the portable device via the body-transmissible signal using the first communication mechanism, and connect with the portable device via the second communication mechanism based upon the information communicated to the portable device via the body-transmissible signal.
