1. A method comprising:
- generating a first signal type and a second signal type in a handheld device, wherein the first signal type is selected to be compatible with a first detection method of a first touch enabled computing device and the second signal type is selected to be compatible with a second detection method of a second touch enabled computing device and wherein the first signal type and the second signal type are different in at least one of frequency or modulation and wherein the first signal type and the second signal type include information related to a same parameter, the parameter related to the handheld device; and
transmitting both the first signal type and the second signal type over the same transmission cycle of the handheld device.

14. A method comprising:
-
detecting a first signal and a second signal from a handheld device with a touch enabled computing device, wherein the first signal and the second signal include information related to a same parameter, the parameter related to the handheld device and wherein the first signal includes the information based on frequency modulation and the second signal includes the information based on digital encoding and wherein the information in the second signal is provided with higher resolution as compared to the information in the first signal; decoding the information in both the first signal and the second signal; verifying a most significant bit in the second signal based on the first signal; and reporting the information as verified to a host of the touch enabled computing device. - View Dependent Claims (15, 16, 17)
