description

The present invention relates to a remote control for controlling an electronic device.

Such a remote control is known from WO 2016/066 778 A1.

The object of the invention is to improve the known remote control.

The object is solved by the features of the independent claims. Preferred developments are the subject of the dependent claims.

According to one aspect of the invention, a remote control for controlling an electronic device comprises a housing with a top side and a bottom side opposite the top side, an operating device held between the top side and the bottom side, which is led out of the housing on the top side, so that a user to operate the electronic device, grip the housing with the fingers of a flange in a transverse direction of the housing on the underside and control commands on the hand with the thumb, which is at least partially oriented in a longitudinal direction of the housing

Operating device can enter, a first infrared camera held between the top and the bottom and aligned with a first image plane, and a second infrared camera held between the top and the bottom and aligned with a second image plane

Infrared camera, the first image plane, the second image plane and one formed by the longitudinal direction and the transverse direction horizontal plane in a cross section of the housing seen in the longitudinal direction a triangle.

The specified method is based on the consideration that the remote control mentioned at the beginning has means for capturing an image of the hand in order to analyze properties characterizing a user. However, the image is taken in the normal operating state by a part of the hand from which hardly any user can be distinguished from the other, because the image plane of the means for capturing the image in the conventional remote control is parallel to the underside of the housing, an area in which the user grips the housing with his fingers. The the user

Characterizing hand lines are, however, more in the palm, which is arranged on the side of the housing and on the top when in use. For this reason, the specified

Remote control proposed to choose the means for taking an image in the form of two infrared cameras, and to align an infrared camera at least partially on one side of the housing in which the user's palm could lie during operation, while the other infrared camera at least partially on the

is aligned with the other side of the housing. In this way, not only are the user's hand lines reliably recorded on the palm of the hand, but there is also a further differentiating variable for the user, namely whether he is

Is right or left-handed, because one of the two infrared cameras will not capture an image and will remain imageless.

In a development of the specified remote control, the triangle is isosceles, the legs being formed by the first image plane and the second image plane and the base by the horizontal plane. In this way, the infrared cameras are aligned axially symmetrically with respect to one another with respect to a height direction of the housing, so that both cameras basically point to the same area of the left

or right hand of a user. Here you can the base angles of the equilateral triangle are between 30 ° and 60 °, preferably 45 °.

In a further development of the specified remote control, the housing is made on the top and / or on the bottom from transparent acrylonitrile-butadiene-styrene, which is preferably with a

Dye is colored. In this way, infrared rays can be passed through the housing without special windows having to be arranged in the housing. In this way, the housing can be manufactured inexpensively and in a short amount of time. The side of the housing should particularly preferably be made of transparent acrylonitrile-butadiene-styrene, towards which the infrared cameras are directed.

In another development, the specified remote control comprises a third infrared camera held between the top and the bottom and aligned with a third image plane. With this third infrared camera, the user's fingers can also be used

are recorded to get a larger picture of the user's fland when characterizing. The third infrared camera can be arranged in the longitudinal direction in front of the first infrared camera and the second infrared camera.

In an additional development of the specified remote control, the third image plane is parallel to the horizontal plane, so that it covers the same image area for left-handers as well as for right-handers.

In another development of the specified remote control, the first infrared camera and the second infrared camera have one

Object-side opening angle of at least 100 °, so that a large area of the user's hand can be captured with the infrared camera.

In a further development of the specified remote control, the cameras are at least partially oriented in the height direction in a height direction from the bottom to the top. In this way, the cameras are on an area between the metacarpus and wrist, and can take up almost the entire palm except the fingers to analyze the user's hand lines.

In yet another further development, the one specified

Remote control first infrared illuminant for illuminating the first image plane in a first angle of incidence and second infrared illuminant for illuminating the second image plane in a second angle of incidence.

The two angles of incidence can each have a value between 0 ° and 45 °, preferably between 10 ° and 35 °, particularly preferably between 20 ° and 25 °. In this way, the furrows of the palm of the hand that form the lines of the hand can be highlighted more clearly and displayed more clearly on the image of the respective infrared camera.

The above-described properties, features and advantages of this invention and the manner in which they are achieved can be better understood in connection with the following description of the exemplary embodiments, which are explained in more detail in connection with the drawing. Show it:

Key 10 and a fourth key 11 includes. The four buttons are provided for moving a control element on a multimedia device (not shown further) and therefore in the four possible ones

Movement directions circumferentially and at a distance of 90 ° around a confirmation button 12.

The keypads 4, 6 together with the control pad 7 form an operating device with which the user can control an electronic device (not shown further). On the first remote control 1 there may be further display means 13, such as small lamps, with which one

User of the first remote control 1, a functional state of the first remote control 1 can be displayed.

As shown in FIG. 2, a printed circuit board 14 with switch contacts 15 is held in the housing between the upper shell 2 and the lower shell 3. On the circuit board 14 is a key mat 16, on which in turn the

Keys 5 of the key fields 4, 6 and those not shown in FIG. 2

Keys 8, 9, 10, 11 of the directional pad 7 are worn. By pressing the buttons 5, 8, 9, 10, 11, the switch contacts 15 can be activated in order to trigger the corresponding functions on the electronic device to be controlled. The structure of such remote controls is known, for example, from DE 10 2015 120 174 A1 and will therefore not be described further below for the sake of brevity.

To operate the first remote control 1, the user places the lower shell 2 in a transverse direction 17 with the fingers of one hand

grasping the case in hand and holding in one of the

Lower shell 2 to the upper shell 3 seen height direction 18 of

Move your thumb to buttons 5, 8, 9, 10, 11 and trigger a desired function on the electronic device to be controlled.

To improve the use of the first remote control 1, the user should be recognized when holding the remote control 1 in the aforementioned manner. With the recognition of the user can

for example, menu navigation individually for the user

program and separate from the menu navigation of another user who also uses the first remote control 1. Information could also be output to the user individually if the user is known. To explain the recognition of a user with the first

Remote control 1 of the present embodiment is referred to FIGS. 2 and 3, which shows a cross section 20 of the first remote control 1 from two different views. The cross section 20 can be seen in FIG. 2 and is divided into three areas that are not further referenced. Two areas of the cross-section run from one side of the first remote control 1 seen in the transverse direction 17 to the center at right angles to the longitudinal direction 19 and are offset in relation to one another in the longitudinal direction. The third area of the cross section is perpendicular to

Transverse direction 17 and connects the other two areas of

Cross-section.

The first remote control 1 has a first infrared camera 21 and a second infrared camera 22 for recognizing the user

Infrared cameras 21, 22 are on the circuit board 14 between the

Upper shell 2 and the lower shell 3 held.

The first infrared camera 21 is aligned with a first image plane 23, which is indicated in FIG. 2 by a dashed line. The first image plane 23, seen in the cross section of FIG. 2, lies at a first angle 25 to a horizontal plane 24 of the housing of the first remote control 1, in which the printed circuit board 14 is arranged in the present embodiment.

The second infrared camera 22 is on a second image plane 26

aligned, which is indicated in Fig. 2 by a dashed square. The second image plane 26, viewed in the cross section of FIG. 2, lies at a second angle 27 in relation to the aforementioned horizontal plane 24.

The first angle 25 and the second angle 27 are selected such that the horizontal plane 24 and the two image planes 23, 26 point to the

Cross section 20 seen form a triangle 28, which is shown in Fig. 3 with a thick dashed line, which the individual

Levels 23, 24 and 26 suggestive dashed lines is superimposed. The first angle 25 and the second angle 27 are chosen the same in the present embodiment. In this way, the two angles 35 and 27 form the base angles of an isosceles triangle 28, in which the legs are formed by the first image plane 23 and the second image plane 26 and the base by the horizontal plane 24. The base angles 25, 27 should preferably be chosen between 30 ° and 60 °. In the present embodiment, a value of 45 ° is selected for the base angles 25, 27.

The first infrared camera 21 and the second infrared camera 22 are designed as wide-angle cameras in the present embodiment. This means that they each have an opening angle 29 of at least 100 °,

preferably at least 120 °. The opening angle 29 of the first infrared camera 21 is limited in FIGS. 2 and 3 by a first opening cone 30, indicated by dashed lines, during the

Opening angle 29 of the second infrared camera 22 in FIGS. 2 and 3 through a second opening cone 31, indicated by a thin dashed line

is limited.

Furthermore, seen in the longitudinal direction 19 after the first

Infrared camera 21 and the second infrared camera 22 a third

Infrared camera 32 can be arranged, which is aligned against the height direction 18. In this way, the third infrared camera 32 is aligned with a third image plane, seen in the height direction

below the lower shell 3 and parallel to the aforementioned

Horizontal plane 24 runs. This third image plane is not indicated in the figures for the sake of clarity. The third infrared camera 32 is indicated in FIG. 4 by a third opening cone 33, which is analogous to the opening angles 31, 32 of the first and second

Infrared camera 21, 22 corresponds to an opening angle within which the third infrared camera 32 captures image information in the third image plane.

The opening angle of the third opening cone 33 can be analogous to the other two opening cones 30, 31 with at least 100 °,

preferably be chosen at least 120 °. When the first remote control 1 is in operation, a user grips the lower shell 3 with his fingers and places his thumb on the upper shell 2 in a substantially aligned manner in the longitudinal direction 19. In this way, he can use his thumb to press the individual buttons 5, 8, 9, 10 and Press 11 and thus trigger the various functions mentioned above on the electronic device to be controlled. To recognize the

User take the two infrared cameras 21 and 22 and

if necessary, the third infrared camera 32 each have an image. Depending on whether the user operates the first remote control 1 with the left or right hand, the first infrared camera 21 or the second one

Infrared camera 22 an image on which the user's hand lines are shown in the area of his palm. Using these hand lines, the user can be distinguished from other users. With the third infrared camera 32, the image area of the hand of the

Increase user and thus increase the information content when recognizing the user.

To highlight the user's hand lines, use the

Printed circuit board 14 be held first infrared illuminant 34, which the first image plane 23 at a first angle of incidence 35 with a first

Illuminate infrared light beam 36. Accordingly, on the

Printed circuit board 14 can also be held second infrared illuminant 37, which illuminate the second image plane 26 with a second infrared light beam 39 at a second angle of incidence 38. The first angle of incidence 35 and the second angle of incidence 38 can each have a value between 0 ° and 45 °, preferably between 10 ° and 35 °, particularly preferably between 20 ° and 25 °. Infrared light-emitting diodes, for example, can be selected as infrared illuminants 34, 37.

As material for the upper shell in the area of infrared cameras 21, 22,

32 an infrared-transparent material should be used.

In this respect, basically any transparent material can be considered. Transparent acrylonitrile-butadiene-styrene has proven to be very suitable because it is colored with a dye and the components inside the housing 2, 3 are visible in the visible area lets hide. However, transparent acrylonitrile butadiene styrene remains transparent to infrared light. The whole is preferred

Lower shell 3 made of transparent acrylonitrile-butadiene-styrene.

Referring to Fig. 5, one becomes the first below

Remote control 1 described an alternative second remote control 40 in which the previously explained idea is carried out alternatively.

The second remote control 40 comprises a frame 41 in which a rocker plate 43 is held so as to be pivotable about a pivot axis 42. Troughs 44 which can be haptically detected are formed on the rocker plate. If a user moves his finger over the troughs 44, he can orient himself due to the haptic detectability. Of the troughs 44 are shown in Figs. For the sake of clarity, not all of them have their own reference numbers.

In the flea direction 18 under the rocker plate 43 is in the second

Remote control 40 a in Figs. Capacitive sensor which can no longer be seen and which can detect the position of a finger of the user on the rocker plate 43. Furthermore, the second remote control 40, seen in the height direction 18, has a rocker plate 43 in FIG. Pressure sensor which cannot be seen further and which can be used to detect whether the user presses the rocker plate 43 against the height direction about the pivot axis 42.

In the operation of the second remote control 40, a user places his finger on the rocker plate 43 in one of the troughs 44. Analogously to the first remote control 1, each trough 44 is assigned a specific function for an electronic device to be controlled. The capacitive sensor detects in which recess 44 the user's finger is located.

If the user presses the rocker plate 43 at the point where he has placed his finger in the recess 44, the corresponding function is triggered.

The structure of the second remote control 40 is described in detail in DE 10 2016 010 920 A1, for example. Since it is on the function of the second remote control 40 for understanding the exemplary embodiment does not arrive, a further explanation is dispensed with below.

The first infrared camera 21 and the second infrared camera 22, which have already been described above, are arranged in the second remote control 40. In contrast to the first remote control 1, in which the two infrared cameras 21, 22 are directed towards the lower shell 3 and thus are oriented counter to the flea direction 18, the two infrared cameras 21, 22 in the second remote control 40 are directed at the

Rocker plate 43 and thus aligned in the height direction 18.

Furthermore, the two infrared cameras 21, 22 are in the first

Remote control 1 seen in the transverse direction 17 from each other

directed away. In contrast, the two infrared cameras 21, 22 are seen in the second remote control 40 in the transverse direction 17

directed towards each other so that the opening cones 30, 31 overlap in an overlap area 45. This arrangement of

Infrared cameras 21, 22 can in principle also be used for the first

Remote control 1 can be selected in which the infrared cameras 21, 22 are oriented counter to the height direction 18.

Analogous to the first remote control 1, the rocker plate 43 can be made partially in the area of the two infrared cameras 21, 22 or completely from transparent acrylonitrile-butadiene-styrene.

The second remote control 40 can be expanded to include all further elements from the first remote control 1, for example the third infrared camera 32 or the infrared lamps 34, 37, their

Alignment, however, corresponding to the alignment of

Infrared cameras 21, 22 must be adjusted.
