Abstract
A device, comprising: a human machine interface (HMI); a bezel framing the HMI; an aperture in the bezel; an ambient light sensor positioned in the aperture and configured to measure intensity of light in a surrounding environment of the device; a proximity detector configured to determine a proximity value of at least one of a user and an object relative to the device based on at least one measurement; and a control unit configured to activate a display of the HMI in response to the proximity value being within a proximity value range.
Claims17
A device, comprising:
- a human machine interface (HMI) comprising a display;
- an ambient light sensor configured to repeatedly measure an intensity of ambient light;
- a proximity detector configured to detect a plurality of proximity values of an object, wherein the plurality of proximity values represent movement of the object, and wherein the proximity detector is configured to emit a signal and to detect a reflected signal reflected from the object;
- and
- a control unit configured to identify a gesture based on the plurality of proximity values control the display based on the gesture;
- and control a frequency of the signal based on the intensity of the ambient light.
A control method of a display of a human machine interface (HMI), the control method comprising:
- measuring an intensity of ambient light in an environment of the HMI;
- detecting a plurality of proximity values of an at object, wherein the plurality of proximity values represent movement of the object, and wherein detecting the plurality of proximity values comprises emitting a signal and detecting a reflected signal reflected from the object;
- controlling a frequency of the signal based on the intensity of the ambient light;
- identifying a gesture based on the plurality of proximity values;
- and
- controlling the display based on the gesture.
