Abstract (en)
[origin: CA2681014A1] A sensing device is provided for interacting with a substrate. The sensin g device has a force sensor for detecting whether the sensing device is inte racting with the substrate and an image sensor for sensing coded data dispos ed on the substrate. The force sensor has a capacitive sensor circuit incorp orating a sensor capacitor having variable capacitance Csen arranged so that an output of the capacitive sensor circuit is proportional to 1/Csen.
