Abstract

The present disclosure relates to a concept of proximity detection. A sequence of keystrokes is captured when a person types on a keyboard placed on a support structure. A sequence of vibrations of the support structure in response to typing on the keyboard is captured with a sensor device associated with a user or a location and in contact with the support structure in proximity to the keyboard. The proximity between the person and the sensor device is checked based on a comparison of the captured sequence of keystrokes with the captured sequence of vibrations.
