Description
Die Erfindung geht aus von einem Informationsanzeigesystem, vorzugsweise einem Head-up-display in einem Fahrzeug, mit einer virtuellen Eingabezone, wobei eine PMD-Kamera die Eingabezone überwacht und eine Auswerteeinheit des Systems derart ausgestaltet ist, dass eine Geste nur dann als Eingabe in der virtuellen Eingabezone erfasst wird, wenn die Geste innerhalb eines definierten Raumbereichs erfolgt.The invention relates to an information display system, preferably a head-up display in a vehicle, having a virtual input zone, wherein a PMD camera monitors the input zone and an evaluation unit of the system is configured such that a gesture only as input in the virtual input zone is detected when the gesture is within a defined space area.

Aufgabe der Erfindung ist es ein Informationsanzeigesystem, insbesondere Head-up-display, in Hinblick auf eine zuverlässige und sichere Eingabe zu verbessern. Die Aufgabe wird durch das erfindungsgemäße Informationsanzeigesystem, dass eine virtuelle Eingabezone aufweist, dadurch vorteilhaft gelöst, dass eine PMD-Kamera die Eingabezone überwacht und eine Geste nur dann als Eingabe in der virtuellen Eingabezone erfasst wird, wenn die Geste innerhalb eines definierten Raumbereichs erfasst wird, wobei das Licht der PMD-Lichtquelle über ein Optik des Informationsanzeigesystems geleitet wird.The object of the invention is an information display system, in particular a head-up display, to improve in terms of reliable and safe input. The object is advantageously solved by the information display system according to the invention, which has a virtual input zone, in that a PMD camera monitors the input zone and a gesture is detected as input in the virtual input zone only if the gesture is detected within a defined spatial region, wherein the light of the PMD light source is passed through an optic of the information display system.
Dieses Vorgehen hat den besonderen Vorteil, dass die Informationsprojektion und das Licht der PMD-Lichtquelle im Wesentlichen denselben Strahlengang aufweisen, so dass zuverlässig eine Dejustierung der Projektionslichtquelle und der PMD-Lichtquelle vermieden werden kann. Ferner erlaubt eine derartige Anordnung der PMD- und Projektionslichtquelle einen größeren Spielraum in der Anordnung der PMD-Kamera. Im Weiteren wird die virtuelle Eingabezone optimal beleuchtet, so dass gültige Gesteneingaben in der Eingabezone zuverlässig erkannt werden können.This approach has the particular advantage that the information projection and the light of the PMD light source have substantially the same beam path, so that reliably a misalignment of the projection light source and the PMD light source can be avoided. Furthermore, such an arrangement of the PMD and projection light source allows greater latitude in the arrangement of the PMD camera. Furthermore, the virtual input zone is optimally illuminated, so that valid gesture inputs in the input zone can be reliably detected.
Bevorzugt ist die PMD-Lichtquelle ein integraler Bestandteil der Projektionslichtquelle des Informationsanzeigesystems. Durch dieses Vorgehen ist es möglich in einfacher Art und Weise ein Beleuchtungspanel bereitzustellen, das unterschiedliche Systeme mit funktionsadäquatem Licht versorgt.Preferably, the PMD light source is an integral part of the projection light source of the information display system. By doing so, it is possible to easily provide a lighting panel that supplies different systems with functionally adequate light.
Besonders praktisch ist es, die PMD-Kamera bzw. die PMD-Lichtquelle und den PMD-Sensor in einem Gehäuse des Informationsanzeigesystems anzuordnen.It is particularly convenient to arrange the PMD camera or the PMD light source and the PMD sensor in a housing of the information display system.
In einem bevorzugten Ausführungsbeispiel ist das Informationsanzeigesystem als Head-up-Display in einem Fahrzeug ausgebildet wobei sich die virtuelle Eingabezone vorzugsweise in einem Raumbereich oberhalb des Lenkrades erstreckt. Dies hat den Vorteil, dass die Gesten in einen Raumbereich erfolgen, der typischerweise beim Führen des Fahrzeugs im Blickwinkel des Fahrers liegen. Somit braucht der Blick des Fahrers, trotz Bedienung der virtuellen Eingabezone, nicht vom Fahrgeschehen abgewendet werden.In a preferred embodiment, the information display system is designed as a head-up display in a vehicle, wherein the virtual input zone preferably extends in a space above the steering wheel. This has the advantage that the gestures are carried out in a spatial area, which are typically in the driver's perspective when the vehicle is being guided. Thus, the driver's gaze, despite the operation of the virtual input zone, does not need to be averted from the driving situation.
Vorteilhaft ist auch möglich die PMD-Kamera im Bereich des Fahrzeugscockpits angeordnet. Aufgrund der Trennung von Kamera und Beleuchtung ist es möglich, die PMD-Kamera in einer sehr kleinen Bauform zu realisieren und an geeigneten Positionen im Fahrgastraum zu platzieren.Advantageously, the PMD camera is also possible in the area of the vehicle cockpit. Due to the separation of camera and lighting, it is possible to realize the PMD camera in a very small design and to place it in suitable positions in the passenger compartment.
Bevorzugt ist der Erfassungsbereich der PMD-Kamera derart ausgelegt, dass sowohl die virtuelle Eingabezone als zumindest auch der Kopf des Fahrers erfasst wird. Vorzugsweise wird neben der Kopfposition auch die Augenposition des Fahrers erfasst. Durch dieses Vorgehen werden nicht nur die Eingaben des Fahrers, sondern auch die Aufmerksamkeit bzw. der Wachzustand des Fahrers überwacht. Darüber hinaus kann durch die bekannte Kopf und/oder Augenposition auch die Darstellung der Informationsanzeige optimiert werden, insbesondere bei autostereoskopischen Projektionen.Preferably, the detection range of the PMD camera is designed such that both the virtual input zone and at least the head of the driver is detected. Preferably, in addition to the head position and the eye position of the driver is detected. By doing so, not only the driver's input but also the driver's attention and waking state are monitored. In addition, the representation of the information display can be optimized by the known head and / or eye position, especially in autostereoscopic projections.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnungen näher erläutert.The invention will be explained in more detail by means of embodiments with reference to the drawings.
