Abstract
An active stylus or a method performed by an active stylus for interacting with a mobile device, wherein the mobile device has at least one sensor (e.g., a thermocouple junction), and wherein the stylus has at least one signal source (e.g., an analog heat source) that produces at least one signal (e.g., at least one analog temperature signal), wherein the at least one signal is configured to be detectable by the at least one sensor of the mobile device. The stylus also has at least one signal adjustment mechanism for changing the at least one signal and also has at least one transmitter (e.g., thermocouple junction) configured to transmit the at least one signal for receipt by the at least one sensor of the mobile device.
