AN INTERACTIVE DISPLAY SYSTEM
Field of the Invention
The present invention relates to advertising display panels .
Background to the Invention
Advertising display panels are used in a variety of public places, such as bus shelters, petrol stations and train stations, usually in the form of posters or panelled billboards. Some of these displays have mechanisms which allow multiple images to be displayed by scrolling a continuous roll of images on a timed cycle. Similarly, advertisement panels formed by rotating slats, with a different image on each side of the slats are known. Electronic displays which display a digital image also have been used. The different images available on these, electronic displays are stored in a memory in the display panel itself. A great deal of research is carried out to determine where particular advertisements or groups of advertisements should be located in order to be most effective. An important factor in deciding where to place advertisements is how many of the target audience will actually be exposed to the advertisement at a particular location.
Whilst electronic display panels and mechanical scrolling mechanisms allow for different advertisements to be displayed at the same location at different times, typically changing advertisements on a set cycle, these displays are not responsive to a changing local environment i.e. a change in the type of people close to the display panel at any given time .
A further problem is that, in all of the above cases, if it is desired to change or add a particular image to the
images available at particular display panel then a person has to visit the site of the display panel in order to do so.
Summary of the Invention
According to a first aspect of the present invention, an interactive display system comprises: a display panel capable of displaying a number of different images; detection means for determining the proximity of mobile communication devices to the display panel, wherein the mobile communication devices each have associated profile data, and the display panel displays a particular image in response to a data profile associated with a proximate mobile communication device.
The present invention allows advertisements which are tailored to a particular socio-economic group to be displayed when one or more members of that group is close to the display panel. The data profile preferably contains information about the purchasing habits of the user. This means that advertisements for products of the type which nearby users are known to purchase can be displayed. Alternatively or additionally the data profile can be indicative of the type of mobile device, which is itself indicative of the user.
Preferably, an interactive display system further comprises : an image receiving means connected to the display panel for receiving image data from a remote source over a cellular network; and, a transmitting means for transmitting image data from an image store to the image receiving means .
The present invention allows a new image to displayed on one or a number of different image display panels
without the need for an operator to visit the site of each display panel. This allows for numerous predetermined display programmes to be implemented cheaply and efficiently. For example, different images can be displayed at different times of day or a series of related images could be displayed on a single display panel, a new image being displayed each day of the week.
Cellular technology allows the location of cellular telephones within a cellular network to be known. The cell in which a telephone is located is easily ascertained. More complex techniques using triangulation allow the location of a telephone within a cellular system to be known more accurately. The location of a stationary advertising display panel within a cellular network is known and therefore it is possible to ascertain the proximity of particular cellular telephones to particular advertising display panels.
Each cellular telephone typically has a data profile corresponding to its owner or its type, either stored on the telephone itself or in a central database. In one example, the detection means for determining the proximity of mobile communication devices to the display panel is a means for determining the proximity of cellular telephones to the display panel in a cellular network. In this example the profile data is stored in a central database. In another example, the detection means for determining the proximity of mobile communication devices to the display panel is a Bluetooth system.
Bluetooth is a universal short-range radio technology that can be used to provide customer premises wireless links for voice, data and multimedia applications. Bluetooth technology allows for the replacement of the many proprietary cables that connect one device with another. For instance, Bluetooth radio technology built into both a
cellular telephone and a laptop would replace the cumbersome cable used to connect them. Printers, PDAs, desktops, fax machines, keyboards, joysticks and virtually any other digital device can be part of a Bluetooth system. Bluetooth provides an interface with existing data networks and a mechanism to form small, private ad hoc groupings of connected devices away from fixed network infrastructures. Bluetooth technology enables high-speed communication between devices that are within 10 metres of each other. This distance can be increased to 100 metres with amplifiers or by increasing the transmission power.
Bluetooth radios operate in the unlicensed ISM (Industrial, Scientific and Medical) radio-band at 2.4GHz. The radio-band is available for worldwide use without licence. Designed to operate in a noisy radio frequency environment, the Bluetooth radio uses a fast acknowledgement and frequency hopping scheme to make the link robust. Bluetooth radio modules can be arranged in a group called a piconet, one of which is the piconet master and the others are slaves.
A single blue tooth radio can support asynchronous data channels, up to three simultaneous synchronous voice channels, or a channel which simultaneously supports asynchronous data and synchronous voice . The asynchronous channel can support an asymmetric link of maximally 721 kb/s in either direction while permitting 57.6 kb/s in the return direction, or a 432,6 kb/s symmetric link. Many Bluetooth radios can operate in the same space and using different radio hopping sequences delivering aggregate delivery rates of over 6 Mb/s.
A full specification of the Bluetooth standard is available from the Bluetooth Special Interest Group (SIG) .
Preferably, the Bluetooth system comprises a Bluetooth radio which is able to form data links with other Bluetooth
enabled devices, having associated data profiles, when the other devices are within range of the Bluetooth radio .
Preferably, the display panel is adapted to display a particular image in response to the data profile associated with a Bluetooth enabled device which has formed a link with the Bluetooth radio.
Preferably, the Bluetooth data link transmits SIM card details to the display panel.
According to second aspect of the present invention, an interactive display system comprises: a display panel capable of displaying a number of different images; a Bluetooth radio able to form data links with other Bluetooth enabled devices,- a display controller for selecting a particular image to be displayed; and, an image store, wherein the display controller selects an image for display from the image store based on one or more data profiles received by the Bluetooth radio from other
Bluetooth enabled devices .
When a Bluetooth enabled electronic device, containing a data profile, enters within range of the Bluetooth radio in the display panel, a connection between the electronic device and the Bluetooth radio in the display panel is established. The data profile is transmitted from the electronic device to the display panel. The display controller receives the profile data and selects an appropriate image based on the profile data. The user of the Bluetooth enabled electronic device may request further information about the image on display to be sent to the electronic device via the Bluetooth link.
If more than one Bluetooth enabled electronic device is within range of the Bluetooth radio in the display panel
then the image that is to be displayed may be determined on a predetermined hierarchical basis, either based on the profile data or on the images.
Brief Description of the Drawings
Examples of the present invention will now be described in detail with reference to the accompanying drawings, in which:
Figure 1 is a schematic diagram of an advertising system according to a first aspect of the present invention; and
Figure 2 is a schematic diagram of an advertising system according to a second aspect of the present invention.
Detailed Description
Figure 1 shows a system according to a first aspect of the present invention, which uses cellular technology. A display panel 1 has an image receiving means 6 which is part of a cellular network. A central image store 8 which is connected to a display controller 2 is connected in turn to an image transmitting means 7. The image transmitting means also forms part of a cellular network and transmits image data to the receiving means 6 so that the image on the display panel 1 can be altered remotely.
A cellular telephone 5, carried by a user, is in communication with a base station containing a location determining means 4. The location determining means is connected to a profile database 3 and the display controller 2.
The location determining means 4 determines the location of cellular telephones in a cellular network according to known techniques . The location of advertisement display panels are stored in the location
determining means so that the location of cellular telephones can be compared with the location of the advertising display panels and when a cellular telephone enters within a certain range of a display panel profile data for that cellular telephone is sent to the display controller 2 from the database 3. The display controller 2 then selects an image to be displayed at the display panel 1 from the image store 8 based on the profile data, and sends appropriate image data to the display panel 1. If more than one cellular telephone, each with a respective data profile, is found to be in range of a particular display panel then image to be displayed is determined by distance from the display panel or hierarchically based on profile data or the available images themselves .
Figure 2 shows a system according to a second aspect of the present invention, using Bluetooth technology. A display panel 11 is provided with a Bluetooth radio 14 having a range of 10 metres. Up to seven other Bluetooth devices 15 entering an area within 10m of Bluetooth radio 14 are able to set up a link with the Bluetooth radio 14, to form a piconet. Devices 16 outside this range cannot form a link with Bluetooth radio 14. Data profiles stored on these other Bluetooth devices 15 are transmitted to and received by the Bluetooth radio 14. The profile data is processed at a display panel controller 12. The display panel controller 12 selects an image for display from an image store in response to the data profile that it receives . A image schedule recorder 13 , for recording the time for which each image in the image store is displayed, is connected to the controller 12. The link is continuously established until the Bluetooth device 15 is out of range, the image on the display panel remains on display until another Bluetooth device- 15 establishes a link. The image
for display is then determined according to the new received data profile as before.
When more than one Bluetooth enabled device 15 enters the range of Bluetooth radio 14, and hence more than one data profile is received by the display controller 12, the display controller selects an advertisement matched to one of the data profiles, giving priority based on a premium paid by the advertisers . Alternatively, the display controller selects one set of data profiles and displays an image on the basis of the chosen data. The choice of data profile is made based on ranking information contained in the profile data. A predetermined number of criteria are used to assign an individual to a "consumer class" so that adverts directed to individuals considered to be high spenders are given priority.
The display panel 11 also contains a data store holding further information about the products and services advertised. A user of a Bluetooth enabled device which is within range of the Bluetooth radio 14 can request further information about the product or service displayed to be sent from the data store via the Bluetooth link to his or her device.
