A system for interacting with a screen without touching it, comprising a source of radiating energy directed into a predefined area, at least one directionally sensitive sensor that detects the radiation when it's reflected off of an object within the predefined area, and a processor that calculates position and motion information of the object and generates therefrom image information, which it sends to a screen where it is displayed.

A thin proximity sensing device includes a transparent plate and a light sensor. The transparent plate includes a first surface and a second surface. The first surface is provided with a light source and a light entering area. The light source is arranged on the first surface. The second surface is provided with a reflector. The light sensor includes a light receiving area. The light sensor is arranged on the transparent plate. The reflector is capable of correspondingly reflecting specific incident light. The specific incident light refers to light that enters the transparent plate through the light entering area on the first surface after the light emitted by the light source is reflected externally, and is incident to the reflector. After reflected by the reflector, the specific incident light is reflected one or more times within the thickness of the transparent plate and is transmitted to the light sensor.

Disclosed is a touchpad system forming a human-machine interface, intended for a vehicle steering wheel. The touchpad system includes a light source illuminating the touchpad and a camera capturing light coming from the touchpad. The touchpad includes a first marker able to reflect the light coming from the light source, and the touchpad, with the exception of the first marker, being transparent to the light emitted by the light source. The system is notable in particular in that pressure on the touchpad causes the touchpad to move and in that, when the touchpad is in a first position, the first marker is not visible to the camera and, when the touchpad is in a second position, the first marker is visible to the camera.
