Detecting the proximity of a wearable processing device 4 to a data processing apparatus 2 based on wireless signals such as Wi-Fi or Bluetooth, received by the data processing apparatus 2 from the wearable processing device 4. A user input is detected with the data processing apparatus 2 which may be a mobile phone, laptop or desktop computer. In response to detecting the user input operation, at least one detection parameter is calibrated for the proximity detection where detection parameters may include distance or signal strength. The processing device may perform authentication of a user in response to detecting proximity of the wearable device. The authentication could include logging the user into a computer, program or website. Provides a convenient technique for calibrating the proximity detection parameter such as configuring the proximity threshold for detection of the device. |
