Detecting touch input provided by signal transmitting stylus
First Claim
1. A system, comprising:
- a propagating medium configured to receive a first touch input provided by a touch input indicator device, wherein the touch input indicator device includes a transmitter that transmits a first signal to the propagating medium when the touch input indicator device contacts the propagating medium and the first signal encodes a digital binary data;
a receiver coupled to the propagating medium, wherein the receiver is configured to receive the first signal, from the touch input indicator device, that has been propagated through the propagating medium; and
a fixed transmitter coupled to the propagating medium at a fixed location and the fixed transmitter is configured to transmit a second signal to be propagated through the propagating medium and received at the receiver; and
a processor configured to detect the digital binary data in the received signal and detect based at least in part on the detection of the digital binary data, the first touch input provided by the touch input indicator device, and identify a location of a second touch input provided on the propagating medium at least in part by analyzing a disturbance by the second touch input to the second signal propagated through the propagating medium.

Abstract
A touch input provided by a touch input indicator device is received on a propagating medium of a receiving device. The touch input indicator device includes a transmitter that transmits a signal to the propagating medium when the touch input indicator device contacts the propagating medium. The signal encodes a digital binary data identifying the signal. The signal that has been propagated through the propagating medium is received at a receiver of the receiving device. The receiver is coupled to the propagating medium. The digital binary data is detected in the received signal. Based at least in part on the detection of the digital binary data, the touch input provided by the touch input indicator device is detected.

18. A method, comprising:
-
receiving a first touch input provided by a touch input indicator device on a propagating medium, wherein the touch input indicator device includes a transmitter that transmits a signal to the propagating medium when the touch input indicator device contacts the propagating medium and the signal encodes a digital binary data; receiving at a receiver the first signal, from the touch input indicator device, that has been propagated through the propagating medium, wherein the receiver is coupled to the propagating medium; detecting the digital binary data in the received signal; detecting based at least in part on the detection of the digital binary data, the first touch input provided by the touch input indicator device; and identifying a location of a second touch input provided on the propagating medium at least in part by analyzing a disturbance by the second touch input to a second signal propagated through the propagating medium, wherein a fixed transmitter is coupled to the propagating medium at a fixed location and the fixed transmitter transmitted the second signal and the receiver received the second signal that has been disturbed by the second touch input. - View Dependent Claims (19)

20. A touch input indicator device, comprising:
-
a transmitter configured to transmit a first signal that encodes a digital binary data; and a contact tip coupled to the transmitter and configured to contact a propagating medium of a receiving device to propagate the first signal through the propagating medium; wherein when the receiving device receives the first signal that has been propagated through the propagating medium, the receiving device detects the digital binary data in the received signal and detects based at least in part on the detection of the digital binary data, a first touch input provided by the touch input indicator device, and a fixed transmitter is coupled to the propagating medium at a fixed location, the fixed transmitter is configured to transmit a second signal to be propagated through the propagating medium and received at the receiving device, and the receiving device is configured to identify a location of a second touch input provided on the propagating medium at least in part by analyzing a disturbance by the second touch input to the second signal propagated through the propagating medium.
