Abstract

The invention relates substantially to a system having cross-linked interactive whiteboards each having interfaces to a common communications network, such that each whiteboard is associated with a network address in a configuration phase, wherein said address is then saved in all whiteboards, and such that a whiteboard having an image change transfers the information of said image change to the other whiteboards in the operating phase with the aid of the saved network addresses, and such that the corresponding image changes are also performed on the remaining whiteboards in a corresponding manner with the aid of said information.

Description

Beschreibung description
System mit interaktiven Whiteboards Die Erfindung betrifft ein System mit interaktiven Whiteboards . Interactive whiteboard system The invention relates to a system with interactive whiteboards.
In vielen Berufszweigen werden in Pro ektbesprechungen, Systemplanungen etc. gemeinsame, spontane Skizzen an einem Whi- teboard, also einer weißen Tafel, als wichtiges Hilfsmittel zur effizienten Kommunikation und Ideenfindung bzw. - strukturierung genutzt. In vielen Fällen sind die Projektmitarbeiter jedoch auf diverse Standorte weltweit verteilt und die Kommunikation entsprechend erschwert. In many occupational sectors, e ect meetings, system planning etc. use common, spontaneous sketches on a whiteboard, ie a white board, as an important aid for efficient communication and brainstorming or structuring ideas. In many cases, however, the project staff are distributed to various locations worldwide and communication is made more difficult.
Es existieren bereits diverse Ansätze für interaktive Nutzung von Whiteboards am Markt. Diese zielen jedoch alle auf die Anbindung an einen PC/Laptop ab, mit dessen Hilfe Präsentati¬ onen bzw. interaktive Elemente am Whiteboard betrachtet und beeinflusst werden können. There are already various approaches for the interactive use of whiteboards on the market. These all aim of connectivity to a PC / laptop by means of which considered PRESENTATI ¬ tions or interactive elements on the whiteboard and can be affected.
Die der Erfindung zu Grunde liegende Aufgabe besteht nun dar¬ in, ein System von interaktiven Whiteboards anzugeben, bei dem mit möglichst geringem Zusatzaufwand praktisch zum glei- chen Zeitpunkt auf allen zum System gehörigen Whiteboards immer das gleiche Bild dargestellt wird, insbesondere auch dann wenn an einem beliebigen Whiteboard des Systems lokal eine Änderung erfolgt. Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 erfindungsgemäß gelöst. Die weiteren Ansprüche betreffen be¬ vorzugte Ausgestaltungen der Erfindung. Which the invention is based task now consists represents ¬ in, to provide a system of interactive whiteboards, wherein with the lowest possible overhead practically on all belonging to the system whiteboards always the same image is displayed for the same possible time, especially even if at Any system whiteboard changes locally. This object is achieved by the features of claim 1 according to the invention. The other claims relate to ¬ preferred embodiments of the invention.
Die Erfindung betrifft im Wesentlichen ein System mit ver- netzten interaktiven Whiteboards mit jeweiligen Schnittstellen zu einem gemeinsamen Kommunikationsnetz, derart dass jedem Whiteboard in einer Konfigurationsphase eine Netzadresse zugewiesen wird, wobei diese Adressen danach in allen White- boards gespeichert werden, dass in der Betriebsphase ein Whi teboard mit einer Bildänderung die Informationen zu dieser Bildänderung mit Hilfe der gespeicherten Netzadressen an die anderen Whiteboards übergibt und dass dort mit Hilfe dieser Informationen die entsprechenden Bildänderungen auch auf den restlichen Whiteboards in entsprechender Weise vorgenommen werden . The invention relates in general to a system with networked interactive whiteboards having respective interfaces to a common communication network, such that a network address is assigned to each whiteboard in a configuration phase, which addresses are then used in all white pages. In the operating phase, a whiteboard with a picture change transfers the information relating to this picture change to the other whiteboards with the aid of the stored network addresses, and with the aid of this information, the corresponding picture changes are also made on the remaining whiteboards in a corresponding manner.
Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. The invention will be explained in more detail with reference to an embodiment shown in the drawing.
Die Zeichnung zeigt dabei ein Minimalsystem mit zwei Interak tiven Whiteboards IWB1 und IWB2, wobei das Whiteboard IWB1 eine Netzschnittstelle IPI1 und das weitere Whiteboard IWB2 eine Netzschnittstelle IPI2 zu einem Netz NE T aufweist. Bei dem Netz handelt es sich typischerweise um das Internet oder ein Intranet oder ein VPN (Virtual private network) . The drawing shows a minimal system with two interactive whiteboards IWB1 and IWB2, wherein the whiteboard IWB1 has a network interface IPI1 and the further whiteboard IWB2 has a network interface IPI2 to a network NE T. The network is typically the Internet or an intranet or virtual private network (VPN).
Die beiden interaktiven Whiteboards IWB1 und IWB2 sind hier in einer Ausführung mit teildurchlässigen Pro ektionsoberflä chen und rückseitigen Beamern Bl und B2 dargestellt. Diese Aus führungs form hat gegenüber einer Beamer-Anordnung von der Anwenderseite bspw. die Vorteile, dass kein Schattenwurf durch den Anwender erzeugt wird und dass der Anwender nicht geblendet wird, wenn er sich bei einer Präsentation den Zuhö rern zuwendet. The two interactive whiteboards IWB1 and IWB2 are here shown in a version with partially transparent pro ektionsoberflä surfaces and rear projectors Bl and B2. This embodiment has the advantages over a projector arrangement from the user side, for example, that no shadows are created by the user and that the user is not dazzled when he turns to listeners in a presentation.
Bei den interaktiven Whiteboards wird bspw. die Position per Triangulation eines speziellen Stiftes kapazitiv, induktiv, per Infrarot, Ultraschall oder Funk ermittelt oder aber bspw auch die Position des ausgestreckten Zeigefingers eines An- wenders per Kamera erfasst. In interactive whiteboards, for example, the position is determined by triangulation of a special stylus capacitively, inductively, by infrared, ultrasound or radio or, for example, the position of the outstretched index finger of a user is recorded by camera.
Bevor die Whiteboards über das Netz NE T kommunizieren können wird in einer Konfigurationsphase zunächst eine Netzadresse zugewiesen. Dies kann bspw. durch manuelle Einstellung einer festen Netzwerkadresse oder aber bspw. dynamisch nach dem Protokoll DHCP erfolgen. Nach der Konfiguration sind allen Schnittstellen der Whiteboards neben der eigenen Adresse auch alle Adressen der weiteren Whiteboards bekannt bzw. dort ge¬ speichert . Before the whiteboards can communicate via the network NE T, a network address is first assigned in a configuration phase. This can be done, for example, by manually setting a fixed network address or, for example, dynamically according to the DHCP protocol. After the configuration are all Interfaces of whiteboards next to their own address and all addresses of the other whiteboards known or ge ¬ stores.
Die Organisation des Informationsaustausches, also welches Whiteboard gerade die Rolle eines Senders und damit gleich¬ zeitig auch welche Whiteboards gerade die Rolle als Empfänger haben, kann auf unterschiedliche Weise gelöst sein. The organization of information exchange, so that whiteboard just have the role as a receiver just the role of a transmitter and thus equal ¬ time also what whiteboards, can be solved in different ways.
In einem einfachen Ausführungsbeispiel werden in der Betriebsphase alle zum System gehörigen Whiteboards bzw. deren Schnittstellen der Reihe nach in einer fest vorgegebenen Reihenfolge zyklisch immer wieder zum Sender. In a simple embodiment, all the whiteboards belonging to the system or their interfaces in the operating phase are cyclically repeatedly returned to the sender in sequence in a fixed sequence.
Der Sender, also das jeweilige sendende Whiteboard bzw. die zugehörige Netzschnittstelle, sendet an die anderen Whitebo¬ ards seine seit dem letzten Senden aktuell vorliegenden Änderungen, sofern solche vorhanden sind, oder aber nur ein Signal zur Synchronisierung der Whiteboards. The transmitter, ie the respective sending whiteboard or the associated network interface sends his since the last transmission date present changes to the other Whitebo ¬ ARDS, where they exist, or only one signal to synchronize the whiteboard.
