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