Description

The invention relates to a user interface and a means of locomotion for interaction with the means of locomotion and, in particular, to a user interface in the form of a finger ring.

Modern means of transport often have a large number of functions that can be operated by a user, such as, for example, selecting a navigation destination and / or a radio station, or also configuring a climate control device for the means of transport. To operate these functions, one or more user interfaces are usually provided, which can be implemented, for example, in the form of an operating unit arranged on the steering wheel and / or in the area of the center console or by using a touch display, etc. Operation of such user interfaces known from the prior art is usually possible. with an alignment of the user's gaze on the respective interface in order to be able to localize its operating elements. Due to an at least briefly associated averting of the view from a current traffic situation, the risk of an accident for the means of transport can increase accordingly. In addition, the user interfaces known from the prior art require a corresponding installation space in the transport means.

In addition, so-called “smart rings” are known from the prior art, which can be worn by a user on a finger and have an integrated user interface. The user interfaces provided by such rings can provide different functions as described below.

US020150277559A1 describes a smart ring which is set up, among other things, by means of a touch display to record operating processes of a user and to transmit them to an external electronic device via a wireless communication interface. In addition, the smart ring is set up in connection with the touch display to show different information to a user.

“Https://mymotiv.com/the-ring” describes a smart ring that is set up to monitor a user's fitness level and to provide an authentication function by performing gestures.

“Https://www.padrone.design/how-it-works” describes a smart ring that is set up to provide computer control similar to control using a computer mouse or a touch pad.

An operation of functions of a means of locomotion on the basis of a finger ring while providing operating functionality similar to conventional user interfaces in the means of locomotion is not provided in the prior art.

It is therefore an object of the present invention to alleviate or eliminate these and other disadvantages of the prior art by means of a user interface and a means of locomotion for interaction with the means of locomotion.

The object identified above is achieved by the features of the independent claims. The subclaims contain preferred developments of the invention.

According to a first aspect of the present invention, a user interface for interacting with a means of transport is proposed. The means of locomotion can for example be a road vehicle (e.g. motorcycle, car, van, truck) or a rail vehicle or an aircraft / airplane and / or a watercraft. The user interface comprises a first ring, a second ring, a first guide device, a power supply interface, a sensor system, an evaluation unit and a first wireless communication interface. The first ring and / or the second ring can be made of any material, such as metal and / or a metal alloy and / or plastic and / or a composite and / or wood. The first ring can also be made of a material different from the second ring. The sensor system can include, for example, a switch, a button, a photodiode, a capacitive sensor, an inductive sensor, a pressure sensor, a heat sensor, a humidity sensor or a distance sensor. In addition, the sensor system can also include any combination of the aforementioned sensors and / or different types of sensors. The evaluation unit can be designed, for example, as an ASIC, FPGA, processor, digital signal processor, microcontroller, or the like, and can be information technology connected to an internal and / or external memory unit.

The first ring is adapted to be worn on a finger of a user of the means of locomotion. Furthermore, the first ring is fitted into the second ring in such a way that the first ring and the second ring are arranged coaxially with one another and are configured to be rotated with respect to one another along a common axis of rotation. I.e. that an outer surface (that is to say an outer circumferential surface) of the first ring lies opposite an inner surface (that is to say of an inner circumferential surface) of the second ring. To ensure smooth and / or high-quality rotary actuation between the two rings, a predefined space between the outer surface of the first ring and the inner surface of the second ring can be created during the manufacture of the two rings, which can be used in particular to provide a bearing between the two Provide rings. This can be done, for example, in the form of a plain bearing by introducing a low-friction material (e.g. graphite, ceramic, plastic, especially nylon, etc.) or a low-friction material pairing in the form of one or more rings and / or by introducing a lubricating film (e.g. Fat or oil) between the outer surface of the first ring and the inner surface of the second ring. As an alternative or in addition, roller bearings can also be provided between the two rings (for example by means of spherical or roller-shaped rolling elements). As an alternative or in addition, a magnetic mounting between the two rings can also take place in that mutually facing, identical magnetic poles based on permanent magnets and / or electromagnets based on magnetic repulsion generate a distance between the first and the second ring. By means of a suitable lateral encapsulation (possibly with the inclusion of sealants) of the space between the first and second ring, it can be ensured that liquids and / or materials introduced for storage cannot escape from the user interface. In addition, the encapsulation can serve to keep foreign substances (e.g. dust, water, etc.) acting on the user interface from the outside away from the stored intermediate space of the user interface.

Also in the sense of a smooth and / or high-quality rotary actuation, an outer surface of the second ring can preferably consist of a material with a high static friction or be coated with this in order to transfer a corresponding force to the second ring on this surface when the user interface is actuated to be able to. For this purpose, the outer surface or at least part of the outer surface of the second ring u. a. covered with a rubberized layer or provided with a knurling, etc.

The first guide device is set up to limit an axial displacement of the second ring with respect to the first ring along the common axis of rotation. In other words, the guide device can prevent the two interlocking rings from being displaced laterally to one another in such a way that they are separated from one another. The guide device can also be implemented implicitly by a suitable bearing between the first ring and the second ring, which can be configured to limit an axial displacement of the second ring with respect to the first ring (e.g. by means of a ball bearing). The sensor system is set up to generate a first signal representing a movement of the first ring with respect to the second ring. The evaluation unit is set up to receive the first signal and, on the basis of the first signal, to generate a second signal and to transmit this to the means of locomotion in connection with the first wireless communication interface. The first wireless communication interface can be, for example, a Bluetooth and / or a WLAN and / or an NFC and / or a cellular radio and / or a low-power wireless interface. It should be noted that the second signal can be identical to the first signal, provided that the first signal generated by the sensor system can be received and processed in unchanged form by a receiver of the second signal in the means of transport. The energy supply interface is set up to receive energy for supplying the user interface.

It should be pointed out that a preferred embodiment of the user interface according to the invention is a finger ring consisting of the first ring and the second ring, but that the user interface according to the invention is not limited to this embodiment. Instead, the user interface according to the invention can also be designed and used, for example, in the form of a bracelet. It should also be pointed out that a size and / or a shape or a design of the user interface and / or a selection of materials for producing the user interface can preferably be specified such that one-handed operation of the user interface is made possible. The user interface can be configured, for example, in such a way that it can be worn on a middle finger of a hand of the user, while it can be operated by means of a thumb of the same hand. In addition, the user interface can also be designed to be carried by any other fingers of the user and, in principle, can be operated by any other fingers of the user.

In an advantageous embodiment of the present invention, the first guide device is implemented on the basis of a lateral border of the second ring by the first ring. For this purpose, a larger width can be selected for the first ring than for the second ring, so that the respective edge sides of the first ring can be raised in such a way that their outer circumference is larger than a circumference of the inner surface of the second ring. In this way, the second ring can be held in the area of the outer surface of the first ring by the raised edge sides of the first ring. Alternatively or additionally, the first guide device can also be implemented on the basis of a circumferential groove in one of the two rings and a web engaging in the circumferential groove in the other of the two rings. The web can be arranged, for example, on the inner surface of the second ring or on the outer surface of the first ring, wherein it can be designed to be circumferential or circumferential in sections. As an alternative or in addition, the first guide device can be implemented on the basis of corresponding spherical shapes of facing surfaces of the first ring and the second ring. As an alternative or in addition, the first guide device can be realized on the basis of magnetic guide elements, which can be formed using an electromagnet and / or a permanent magnet.

In a further advantageous embodiment of the present invention, the sensor system is set up, a pressure exerted in the radial direction on the second ring and / or a radial displacement of the second ring with respect to the first ring and / or a tilting of the second ring with respect to the first ring and / or to detect and distinguish an axial displacement of the second ring with respect to the first ring and / or a contact with the first ring and / or the second ring. For this purpose, in particular the types of sensor described above can be arranged at one or more suitable positions within or on the user interface. A pressure exerted on the second ring in the radial direction can, for example, by means of a piezo sensor arranged on the outer surface of the second ring (e.g. a plurality of circumferentially arranged piezo elements and / or a piezo film) and / or by means of a piezo sensor arranged on the outer surface of the first ring Piezo elements (for example also a plurality of circumferentially arranged piezo elements and / or a piezo film) are detected. A displacement and / or tilting of the second ring with respect to the first ring can be determined, for example, by means of capacitive sensors which can detect respective changes in distance between the first and the second ring due to capacitive changes. The first ring and / or the second ring can be touched, for example, by means of a touch sensor and / or a touch display. In this way, a large number of different operating options can be provided by means of the user interface, which make it possible to operate a large number of different functions of the means of transport (e.g. scrolling through a selection list by rotating the second ring around the first ring or confirming a message using exerting pressure on the first ring). It should be pointed out that the sensor system can also preferably be set up to differentiate between different shifting, tilting, or pressure gradations. In this way, the evaluation unit can carry out different controls in the means of locomotion as a function of the respective gradations represented by the first signal.

In a further advantageous embodiment of the present invention, the energy supply interface is set up to receive energy from an energy store and / or a solar cell and / or an electrical generator and / or a wireless energy transmission device of the user interface and / or from a source apart from the user interface. An acceptance of energy away from the user interface can in particular be energy provided by the means of locomotion. An energy store integrated into the user interface can preferably be a chargeable energy store, which can be charged inductively using an alternating magnetic field and / or via electrical contact, for example. An electrical generator integrated into the user interface can preferably be a rotary generator (dynamo) which, for example, based on a conductor coil arranged in one of the two rings and a plurality of permanent magnets, which can be arranged in the other ring, in the course of a rotation of the second Ring can generate electrical energy with respect to the first ring. Such a rotary generator integrated into the user interface can preferably be electrically coupled to the energy store integrated into the user interface, so that the energy store can be charged by rotating the two rings relative to one another. In this context, it is also conceivable to provide a rotating wheel in the interior of the means of locomotion, which the user can bring into contact with the second ring in such a way that the rotating wheel sets the second ring in a rotational movement, so that due to this rotational movement in the rotary generator integrated in the user interface can generate electrical energy.

In a further advantageous embodiment of the present invention, the first guide device has a locking mechanism which is set up to activate or deactivate the guide function of the first guide device. The aim of this advantageous embodiment is to be able to separate the rings from one another in the axial direction in a deactivated state of the guide function. For example, the above-described lateral Rims of the second ring can be removed by the first ring by screwing the side rims on the first ring, whereby the side rims can be unscrewed from the first ring accordingly. Alternatively or additionally, the circumferential or partially circumferential web connecting the two rings can be designed in such a way that it can be sunk into a respective ring by actuating a lever or a button or another element so that the rings can then be separated from one another .

A separation of the two rings can be used particularly advantageously when the first ring and / or the second ring are to be replaced by an alternative first ring and / or an alternative second ring. Replacing the first ring can be useful, for example, when an inner radius of the first ring is to be adapted to the circumference of a finger of the user. In such a case, the first ring can be replaced by an alternative first ring, the inner radius of which is larger or smaller than that of the first ring, while the outer radius of the alternative first ring can be identical to the first ring, so that the alternative first ring in the second ring or an alternative second ring can be fitted. As an alternative to replacing the first ring, an additional adapter ring can also be fitted into the first ring in order to achieve an adaptation to a respective finger of the user. Replacing the first ring and / or the second ring by a respective alternative ring can in particular also be advantageous if an energy store is provided in one of the two rings, which in this way can be exchanged with the respective ring. In this way, for example, a charging process within the user interface can be avoided by replacing the ring to be replaced by an alternative ring with a charged energy store.

In a further advantageous embodiment of the present invention, the user interface further comprises a latching device and / or an end stop, the latching device being set up to provide a plurality of predefined latching positions permanently or depending on the context between the first ring and the second ring along the common axis of rotation. The end stop is set up to provide a predefined end stop position permanently or depending on the context for a rotation between the first ring and the second ring. Both the locking device and the end stop can be implemented on the basis of mechanical and / or magnetic elements. Permanent locking positions and / or end stop positions can be implemented, for example, by means of a spring-loaded locking lug on one of the two rings and a plurality of locking notches and / or slots corresponding to the locking lug in the other of the two rings. Alternatively or additionally, the permanent latching positions and / or end stop positions can be implemented by means of a plurality of permanent magnets, which can be arranged at a predefined latching distance along one of the two rings, while one or more corresponding permanent magnets can be arranged on the other of the two rings. In this way, in the course of a rotation of the second ring around the first ring, depending on a respective angle of rotation, forces that can be differentiated by the user can be generated which counteract the rotation to different degrees and can thus generate corresponding latching and / or end stop positions. The end stop can also be designed in the form of a hard end stop, which can be implemented by an end stop element fixedly arranged on the first ring and a fixed end stop element arranged on the second ring, which can meet at a predefined angle of rotation of the two rings. In addition, it is also conceivable to provide two different end stop positions in order to be able to limit a total angle of rotation of the user interface.

A context-dependent provision of the end stop positions or the latching positions can be advantageous in particular when an operation of the user interface is to correspond to a respective operating context. Such an operating context can result, for example, from a menu of a menu tree of an on-board computer system of the means of transport, which can, for example, display a specific number of selectable elements. By adapting the respective latching and / or end stop positions to a respective menu context, the user interface can be operated particularly intuitively. The context-dependent provision of the end stop position or the latching positions can, for example, take place on the basis of an electromagnet which, in conjunction with the above-described latching and / or end stop positions on a permanent magnet basis, can be activated or deactivated as required. To implement the context-dependent end stop positions or latching positions, the evaluation unit according to the invention can be set up to receive information about a respective operating context from the means of transport via the wireless communication interface and to take this information into account when activating the electromagnet (s).

In a further advantageous embodiment of the present invention, the second ring comprises a display and / or a touch display for interaction with the user. The display and / or the touch display can be connected to the evaluation unit according to the invention in terms of information technology. This also enables information to be output in the user interface, the information being generated by the evaluation unit and / or being able to be received by the means of transport.

In a further advantageous embodiment of the present invention, the user interface further comprises a third ring and a second guide device, the third ring being arranged parallel to the second ring and the first ring being fitted into the second ring and the third ring in such a way that both the second ring and the third ring are arranged coaxially to the first ring and are designed to be rotated relative to one another along the common axis of rotation. The second guide device is set up to limit a displacement of the third ring with respect to the first ring in the direction of the common axis of rotation. It should be noted that the first guide device and the second guide device can be identical. This can particularly apply when the first guide device is implemented in the form of a lateral border of the second ring by the first ring, since such a lateral border can border the second ring and the third ring lying parallel to it at the same time. In addition, features, feature combinations and the advantages resulting therefrom with regard to the first ring can also be used in connection with the third ring, which is why reference is made to the above statements on the first ring to avoid repetition.

It should be noted in general that the evaluation unit, the wireless communication interface, the energy supply interface, the energy store, the sensors, the latching device, the first and second guide device, the locking mechanism and the end stop are basically divided in any way between the first ring and the second ring as long as the functions of the present invention can be maintained.

According to a second aspect of the present invention, a means of locomotion is proposed which comprises a second wireless communication interface and a control device, the second wireless communication interface being set up to receive a second signal representing an operating process from a user interface according to one of the preceding claims. In addition, the means of locomotion is set up to transmit the second signal for operating the control device to the control device.

In an advantageous embodiment, the means of transport further comprises a charging device for the user interface, wherein the charging device is set up to receive the user interface by means of a storage area and / or a storage device adapted to an external shape of the user interface and the user interface wirelessly and / or wired via an energy supply interface of the Load the user interface. For this purpose, the storage area and / or the storage device can comprise electrical contacts which can be connected to corresponding electrical contacts of the user interface. As an alternative or in addition, the means of locomotion can generate an alternating magnetic field in the area of the storage area and / or the storage device, which is set up to inductively charge the user interface.

In a further advantageous embodiment, the charging device is arranged inside and / or on the steering wheel and set up to charge the user interface wirelessly while the means of locomotion is driving. For this purpose, a magnetic alternating field for an inductive charging process of the user interface can be generated for example in the area of a main contact surface of a left hand of the user and / or in the area of a main contact surface of a right hand of the user on the steering wheel.
