Abstract
Proximity of a wearable processing device to a data processing apparatus is detected based on wireless signals received by the data processing apparatus from the wearable processing device. A user input operation is detected which comprises a physical interaction with the data processing apparatus. In response to detecting the user input operation, at least one detection parameter is calibrated for the proximity detection. This provides a convenient technique for calibrating the proximity detection which does not require complicated operations from the user.
