Touchless device interfaces

A system for receiving input to control an apparatus, the system comprising:

• a display for displaying video content based on display signals;
• one or more capacitive sensors which are sensitive to disturbances in their electric fields caused by a human body part in proximity to a user-facing side of the display;
• a controller connected to receive one or more capacitive sensor signals from the one or more capacitive sensors to generate a control signal based on the one or more capacitive sensor signals, the controller connectable to the apparatus to provide the control signal as an input to a control system of the apparatus and to thereby cause the control system of the apparatus to operate the apparatus based on the control signal;
• wherein at least one electrode of each of the one or more capacitive sensors is located on a user-facing side of the display, the at least one electrode of each of the one or more capacitive sensors fabricated from transparent conductive material, so that the human user can see the display through the at least one electrode of each of the one or more capacitive sensors.

A system for receiving input for controlling an apparatus comprising a display, the system comprising:

• one or more sensors responsive to touchless input made by a human user and for generating one or more corresponding sensor input signals;
• and,
• a controller connected to receive the one or more sensor input signals from the one or more sensors and configured to generate, based on the one or more sensor input signals, a corresponding control signal;
• the controller connectable to the apparatus to provide the control signal as an input to a control system of the apparatus to thereby cause the control system of the apparatus to operate the apparatus based on the control signal;
• wherein the one or more sensors comprise one or more capacitive sensors which are sensitive to disturbances in their electric fields caused by a human body part in proximity to the one or more capacitive sensors;
• wherein at least one electrode of each of the one or more capacitive sensors is located on a user-facing side of the display, the at least one electrode of each of the one or more capacitive sensors fabricated from transparent conductive material, so that the human user can see the display through the at least one electrode of each of the one or more capacitive sensors.
