Furthermore, a particularly rapid localization of the object, in particular of the finger, is possible, so that a module with very flexible application possibilities, in particular a module for recognizing user commands by detecting user gestures, is realized. Thereby improving user comfort over the prior art. The modular-based construction allows individual components or the entire module to be adapted more flexibly to the requirements of the respective electrical device. The Human-Machine interface is also referred to herein as a Human-Machine-interface (HMI), and the module is also referred to herein as an HMI module. The human-machine interface is in particular a virtual interface, that is to say a user interface for inputting user gestures and/or commands by means of contactless detection of objects.
A human-machine interface is to be understood in particular as a user interface: the user can interact with the electrical device and/or the module via the user interface in such a way or can enter commands that the electrical device and/or the module is controlled and/or operated by the user. The module serves in particular as a command input device for an electrical apparatus. Preferably, the object is a finger, a pen or another object which is positioned in the positioning area by the user and/or moved in the positioning area by the user. The localization means, in particular, that the distance between the object and the module and/or the position of the object relative to the module is detected using a primary beam and a secondary signal, wherein the secondary signal is generated by the interaction of the primary beam with the object and is returned to the module. Interaction here means, in particular, a reflection of the primary beam on the object. Preferably, the light source is configured to generate a primary beam of radiation into the location area, wherein the primary beam is, for example, a beam of visible light or a beam of infrared light.

Fig. 1 shows a schematic view of a module 2 according to an embodiment of the invention. The module 2 is configured here for determining the position of the object 4 arranged in the radiation surface 30. The module 2 is configured such that the primary beam 3 executes a scanning movement substantially along the radiation surface 30, wherein the secondary signal 5 is detected if the primary beam 3 interacts with an object 4 positioned in the radiation surface 30 such that the secondary signal 5 is generated. For example, if the primary beam 3 radiates in the radiation direction 101 and impinges on the object 4 and if the object is positioned in the radiation plane 30 in the radiation direction 101 as seen by the module 2, the secondary signal 5 is generated by reflection of the primary beam 3 on the object 4.
The module 2 is configured to locate the object 4 by detecting the secondary signal 5, wherein the locating of the object 4 is carried out by means of a distance detection and/or an intensity detection, wherein the distance detection is carried out in particular by means of a time-of-flight method and/or the intensity detection is carried out by means of an intensity detection, wherein the intensity detection comprises an intensity comparison between the measured intensity of the secondary signal 5 and a reference intensity. For example in a reference measurement and storing the reference intensity in the module 2.
The localization position of the object 4 represents a position determination of the entire object or of only one object part (for example, a projection point on the object surface of the object 4 produced by the primary beam 3), wherein the position determination relates to a determination of the distance or spacing between the module 2 and the object 4 or the object part and/or to a determination of the position of the projection point (associated with the object part) relative to a further projection point (associated with a further object part), wherein the projection point and the further projection point are produced in particular at different times during the scanning movement.

This provides a modularly constructed module 2 which can be flexibly adapted to a plurality of different electrical devices 1 and/or applications, for example, according to the combined component principle.
In an exemplary embodiment of the module 2, the first sub-module 21 is a light module 21 configured for generating the primary beam 3 and/or the further primary beam 3'; and/or the second sub-module 22 is a scanning module 22 configured for generating a scanning motion of the primary beam 3 and/or a further scanning motion of a further primary beam 3'; and/or the third submodule 23 is a first control and/or detection module 23 configured for generating a detection signal depending on the secondary signal 5 and/or the further secondary signal 5'; and/or the fourth submodule 24 is an analysis processing module 24 for generating positioning information; and/or, the fifth submodule 25 is a second control and/or detection module 25; and/or, the sixth submodule 26 is a control module 26 for controlling the energy supply; and/or, the seventh submodule 27 is a camera module; and/or the eighth submodule 28 is a communication module 28 configured for communication with the electrical device 1 and/or data transmission to the electrical device 1.
Fig. 2 shows a module 2 according to an embodiment of the invention. The module 2 has a light source 6 for generating the primary beam 3. The light source is preferably a laser diode, for example in the form of a surface emitting laser. The primary beam 3 generated by the light source 6 is in particular a beam of visible light 3, i.e. light of a wavelength of about 380 nanometers (nm) to 780nm, or a beam of Infrared (IR) light 3.
The module 2 has a scanning mirror structure 7, which has a microelectromechanical scanning mirror element 7. The module 2 is configured in particular such that the primary beam 3 is deflected by the scanning mirror arrangement 7 in such a way that the primary beam 3 extends substantially along the (planar) radiation surface 30. The micromechanical scanning mirror element 7 can be adjusted into a plurality of deflection positions in the region between the two maximum deflection positions (of the scanning mirror element 7 or of the further scanning mirror element 7'). In the first of the two maximum deflection positions, the primary beam 3 is radiated by the scanning mirror arrangement 7 along the radiation surface 30 in the first radiation direction 101'. In a second of the two maximum deflection positions, the primary beam 3 is radiated by the scanning mirror arrangement 7 along the radiation surface 30 in a second radiation direction 101'. The localization boundaries 101 ', 101 ″ of the localization zone 30 are defined by the first radiation direction 101' and the second radiation direction 101 ″. In particular, in this embodiment, the terms positioning region 30 and radiation surface 30 have the same meaning. The micromechanical scanning mirror element 7 is configured in particular such that, when the scanning mirror element 7 is loaded with a control signal, the scanning mirror element 7 executes a deflection movement between the two maximum deflection positions. The primary beam 3 is in particular a laser beam 3, for example a continuous laser beam 3 or a pulsed laser beam 3.
In particular, the primary beam 3 is moved during a scanning movement having a scanning frequency, wherein the scanning frequency is associated with a scanning period of the scanning movement. In particular, the primary beam 3 is scanned or swung during the scanning cycle from a first position-finding boundary 101 '(indicated by the primary beam with the reference numeral 3') to a second position-finding boundary 101 '(indicated by the primary beam with the reference numeral 3 ") and back again to the first position-finding boundary 101'. The scanning frequency is preferably between 1 and 2000 hertz (Hz), particularly preferably between 5 and 500 Hz, very particularly preferably between 10 and 200 Hz.
In deflection positions in the region between the maximum deflection positions of the scanning mirror element 7, the primary beam 3 is radiated in the radiation direction 101. If an object 4, for example a user's finger 4, is arranged or positioned in the radiation area 30 in such a way that the object 4 touches the radiation area 30 or intersects the radiation area 30, a secondary signal 5 is generated by the interaction, i.e. for example reflection, of the primary beam 3 with the object 4. For example, the object 4 is moved into the radiation surface 30 by an object movement of the object 4 in a projection direction 103 perpendicular to the radiation surface 30, so that the object 4 is arranged or positioned in the radiation surface 30. Here, a secondary signal 5 is generated if the primary beam 3 (during the scanning movement) radiates in the radiation direction 101.
The module 2 comprises optical detection means 9, 9' configured for detecting the secondary signal 5, said optical detection means having an optical detection element 9, for example a photodiode 9.

Preferably, the module 2 is configured to generate a position detection signal with respect to the deflected position of the scanning mirror element 7 and/or a further deflected position of the further scanning mirror element 7' during the detection of the secondary signal 5 in such a way that the position-finding information is generated in a time-resolved manner from the detection signal and the position detection signal. The position-finding information comprises, in particular, distance information about the distance of the object 4 from the module 2 and/or orientation information about the orientation direction of the object 4 relative to the module 2 and/or position coordinates about the position of the projected point on the object surface of the object 4.

The support surface 10 extends here mainly along a plane 100. The module 2 is configured in particular such that, with the module 2 supported with the module underside 2' on the support surface 10, the radiation surface 30 and the main extension plane 100 are arranged substantially parallel to one another and have a radiation distance 11 between the support surface 10 and the radiation surface 100 in a projection direction 100 perpendicular to the radiation surface 30.

The primary beam 3 directed toward the scanning mirror arrangement 7 is preferably deflected and directed toward the wide-angle optics 8 in such a way that the primary beam 3 is deflected by the wide-angle optics 8 into the radiation surface 30. By means of the wide-angle optics 8, it is advantageously possible according to the invention to select the angle of the sweep of the primary beam 3 to be greater than the scan angle of the scanning mirror 7. The beam-shaping optics of light source 6 are preferably matched to wide-angle optics 8 in such a way that the beam-shaping of primary beam 3 after wide-angle optics 8 does not exceed a diameter of 5 mm, preferably 3 mm, more preferably 1 mm, and very particularly preferably 0.5 mm.

The measuring areas 30, 30 'are formed by the radiation surface 30 and the further radiation surface 30'. The further scanning movement of the further primary beam 3' and the scanning movement of the primary beam 3 are realized in particular at the same scanning frequency or at different scanning frequencies and/or synchronously or asynchronously. The wide-angle optics 8 here has a mirror element 8' and a further mirror element 8 ″. The primary beam 3 is directed by the scanning mirror element 7 toward the mirror element 8 'and the other primary beam 3' is directed toward the other mirror element 8 ″.

The electrical device 1 is here a portable tablet computer, wherein the display unit 1' itself is touch insensitive, that is to say the touch screen functionality on said tablet computer is provided solely by means of the module 2 or by means of a man-machine interface. The device 1 has in particular a module 2 and/or a further module 2 (not shown here).
Fig. 12 shows an electrical device 1 according to an embodiment of the invention, which substantially corresponds to a further embodiment according to the invention. The electrical device 1 is, for example, a television set 1, which has, in particular, a module 2 and/or a further module 2'. By using at least two modules 2, 2', it is advantageously possible to implement multi-touch gesture recognition. In particular, a multi-touch display screen, that is to say a screen with multi-finger gesture recognition, is thereby advantageously provided on the electrical device, wherein the module 2 and/or the further module 2 'on the display unit 1' enable gesture-based touch-sensitive data input. The multi-touch function here means that simultaneous multi-touches of the display unit 1' by means of the object 4, for example by means of a finger 4 of a user, are recognized, instead of detecting only one single touch point at the same time. The user can, in particular, tap on elements displayed on the screen, move them or select a plurality of them simultaneously. An application example is the enlargement and rotation of an image by moving two fingers away from each other or rotating them relative to each other.
Fig. 13 shows a signal change process of a positioning signal change process according to an embodiment of the present invention. A method for recognizing a user command by means of the module 2 according to the invention is described here. The module 2 is configured to generate a locating signal for deriving the command information, wherein a locating signal value (reference 500 ") as a function of time (reference 500') is shown here. The user moves, for example, an object 4 (for example a finger or a pen) in order to enter a user command, wherein the position-finding signal is generated by the module 2 in dependence on the movement of the object 4. In this case, a plurality of partial movements of the object 4 are detected, wherein, for example, the object 4 is moved into an inactive position, wherein the object 4 is positioned outside the radiation surface 30 in the inactive position; or to move the object 4 into an activated position, in which the object 4 is positioned in the radiation surface 30. This means, for example, that, in the case of a movement of the object 4 parallel to the radiation surface 30, a further activated state which is independent of the activated state is detected when the distance between the respective detected positions of the object 4 is greater than a reference distance.
In this case, the movement of an object from the inactive position into the active position is referred to as an active movement and the movement of an object from the active position into the inactive position is referred to as a deactivated movement. In the position-finding signal shown in fig. 12, firstly the inactive state of the object 4 is detected during a first time interval (see reference numeral 501), wherein subsequently a first active movement of the object 4 is detected, wherein subsequently the active state of the object 4 is detected during a second time interval 502 in the first time interval 501, wherein subsequently a first inactive movement of the object 4 is detected, wherein subsequently the inactive state of the object 4 is detected during a third time interval 503 in the second time interval 502.
Preferably, when the inactive position of the object 4 is detected during a defined time period directly following the third time interval 503, the command information with information about the single click is derived from the position finding signal. Otherwise (for example, as shown in fig. 12), a second activation movement of the object 4 is detected in a third time interval 503, wherein an activation state of the object 4 is detected during a fourth time interval 504 following the third time interval 503. Thereafter, a second deactivation movement of the object 4 is detected, so that during a fifth time interval 505 following the second deactivation movement the inactive bit state of the object 4 is detected. In this case, the active state of the object 4 is detected during a sixth time interval 506 after the third activation movement of the object 4.
In this case, preferably, the command information with information about the user command (for example, in this case about a double click) is derived from the position-finding signal, in particular when an inactive position of the object 4 is detected during a predetermined time period directly following the fifth time interval 505.
