A wearable device for establishing a communication path with a user of the wearable device and at least one individual, the wearable device comprising:

• a display;
• at least one sensor configured to provide an output indicative of a viewing direction of the user;
• and
• at least one processing device configured to:
• monitor the viewing direction of the user based on the output of the at least one sensor;
• determine, based on the monitored viewing direction, whether the user is looking in the direction of the at least one individual;
• and
• establish the communication path between the user and the at least one individual if the user is determined to be looking in the direction of the at least one individual;
• wherein determining, based on the monitored viewing direction, whether the user is looking in the direction of the at least one individual includes:
• tracking a time duration during which the gaze of the user's eyes is in the direction of the at least one individual;
• and determining that the time duration is greater than a predetermined dwell threshold.
