Definitions

  • This invention relates to a new information delivery system and a method of providing information delivery.
  • Cellular telephone systems currently provide the operators thereof with information about the geographic position of a user to within the accuracy of one "cell", which is often several square kilometres in size, or one sector of a cell.
  • Systems now in development will soon enhance the positioning resolution down to a few metres or better, either by integrating GPS (the satellite-based Global Positioning System) receivers into each telephone, or by taking advantage of the existing cellular radio signal through measurement of time of arrival, time difference of arrival (for example the CURSOR system designed by Cambridge Positioning Systems Ltd.) or angle of arrival (for example the TeleSentinel system from KSI Inc.)
  • Portable devices which act as audio guides for museums, providing audio appropriate to the item that a visitor is viewing, or room in which he or she is standing (referred to hereafter simply as a "location"). These work in one of several ways:
  • Cassette player The most common type is simply an audio-cassette player controlled manually by the visitor, talking him or her through the various locations. The user may pause or rewind the programme.
  • Radio station A very low-power radio station broadcasts from each location (possibly with low-frequency magnetic fields or infra-red), and a receiver carried by the visitor receives only the information local to the item he or she is viewing (the user may possibly be able to tune to different radio channels for different languages).
  • An example is the Easy Guide device produced by ColourArt.
  • the guide narrations are stored on the portable device itself, for example in solid-state memory or on disc, and coded radio transmitters in each location trigger the device to play back the appropriate narration - an example is the Easy Guide device with optional Flash card.
  • the "cassette player” approach has the following limitations: • It is entirely manual - the device tells the user where to walk next and the user must follow the directions to hear audio that is relevant.
  • Audio playback is not context-sensitive.
  • the "radio station” approach has the following limitations:
  • a local information delivery system comprising either a low-power transmitter placed at each of a plurality of locations and a receiver and processor attached to a standard wireless communications device, or a low-power transmitter attached to a standard wireless communications device and a receiver and processor placed at each of a plurality of locations, the processor in either case being adapted to distinguish a unique code transmitted by the transmitter and thereby to send a message to a central control system identifying and locating the wireless communications device and thereby to deliver location-specific information to the wireless communications device.
  • Such a system is advantageous because it combines a familiar, standard, low-cost wireless communications device (which a visitor may already own) together with a low-cost device which controls the flow of information to the wireless communications device, providing a low-cost, location-sensitive solution to information delivery, with potentially very high spatial resolution.
  • a wireless communications device in which:
  • a low-power transmitter is attached to the wireless communications device
  • a plurality of receivers each including a processor is distributed over a plurality of locations;
  • the low-power transmitter transmits a code unique to that transmitter to at least the nearest of said receivers;
  • the processor of said receiver sends a signal to a central control system including both the code and information regarding the location of the wireless communications device with reference to the locations of said plurality of receivers;
  • the central control system identifies and locates the wireless communications device by way of the code and the location information provided by the processor and delivers location-specific information to the wireless communications device.
  • a wireless communications device in which:
  • a receiver including a processor is attached to the wireless communications device
  • each of the plurality of low-power transmitters transmits a code unique to that transmitter, the code being receivable by said receiver;
  • the processor upon reception of said code from said receiver, sends a signal to a central control system including both the code and information regarding the location of the wireless communications device with reference to the locations of said plurality of transmitters;
  • the central control system identifies and locates the wireless communications device by way of the code and the location information provided by the processor and delivers location-specific information to the wireless communications device.
  • the wireless communications device may be of any common type, being for the purposes of this invention any system which provides its user with information received from a network. It may for example provide information via audio (possibly via a headset), or text (possibly via Short Message Service (SMS), Wireless Application Protocol (WAP), HTML or other network protocol), or even video. It may additionally allow some form of user-input back to the central control system (including, but not limited to, DTMF (Dual-Tone Multi-Frequency) keypad tones).
  • DTMF Dual-Tone Multi-Frequency
  • the low-power transmitter may be of any type, accepting digital data and transmitting it either as electromagnetic waves in the visible, infra-red or radio- frequency parts of the spectrum, or emitting audible tones, possibly ultrasonic, and using any modulation scheme including but not limited to amplitude-keying, amplitude modulation, frequency-keying, frequency-modulation, frequency-hopping or spread-spectrum.
  • the transmitter may operate by modulating an existing form of radiation, for example a light bulb.
  • the receiver is matched to the characteristics of transmissions from the transmitter, translating the received data back into digital form.
  • a microprocessor or microcontroller adapted for use with the system and methods hereinbefore described, the microprocessor or microcontroller being operable to process data received by the receiver and to cause data regarding a location of the wireless communications device to be sent to the central control system.
  • the processor is attached to the receiver and may be any type of microcontroller or microprocessor, running a software program which interprets the data from the receiver and sends a message to the central control system informing it of the location of the wireless communications device.
  • the location-based receiver sends information about nearby transmitters (users) to the central control station, possibly by wires, radio transmission or other means.
  • the user-based receiver sends information about nearby transmitters (locations) to the central control station, possibly by sending DTMF tones or other signalling either carried over the wireless communications device's voice, data or network control bands.
  • the central control system is interfaced to each user's wireless communications device via the device's normal network, which might be a dialled-up cellular connection, local wireless network, or some other networking protocol such as Wireless Application Protocol (WAP), point-to-point infra-red data transfer possibly using the Infra-red Data Association protocol or Bluetooth (a short-range radio- frequency protocol from Ericsson et al. which enables two or more wireless devices to be networked together in a "scatternet"), possibly also travelling via the Public Switched Telephone Network (PSTN).
  • WAP Wireless Application Protocol
  • Bluetooth a short-range radio- frequency protocol from Ericsson et al. which enables two or more wireless devices to be networked together in a "scatternet"
  • PSTN Public Switched Telephone Network
  • the central control system receives messages from the processing means attached to the receiver, it modifies the data that it delivers to the wireless communications device.

  • a wireless headset e.g. using the Bluetooth wireless protocol
  • audio information by way of earphones and, optionally, visual information by way of a head-up display device.
  • Each receiver may optionally have a means to compare the signal- strength or time-of- arrival of transmissions from several transmitters, allowing the system to determine the location of the user to a greater resolution than simply to the nearest transmitter or receiver.
  • the system may be partly controlled by the location system described, and partly by the user, allowing the user to operate either in “automatic” mode with the system providing appropriate information as he or she moves about, or to take “manual" control at any point, for example to hear information paused or repeated, or to hear more or different information.
  • the transmitter or receiver attached to the wireless communications device may:
  • the receiver may optionally be adapted to enter a state of very low power- consumption until a new transmission is detected.
  • Each location may be fixed or may be mobile, with a system potentially comprising some fixed and some mobile locations.
  • Both a transmitter and receiver may optionally be attached to the wireless communications device, allowing two-way information transfer independent of the wireless communications device's network. This effectively makes every "user” also a “location”, allowing users to obtain information about each other (social systems).
  • the system may detect attempts to take the attached device away from the zone of operation (for example, the museum) and remind the user to return the device.
  • the zone of operation for example, the museum
  • the central control system may be provided with a means for users to leave a message about each location, in either voice, text or other formats, which will then be available to other users.
  • the central control system may provide information about the location of users, to a central display, or to other users or groups of users, or to an external network such as the Internet, providing a useful means of finding lost children, parents etc., and of tracking customer behaviour.
  • the transmitting means of this invention may be any transmitting means already incorporated into the wireless communications device, such as those described hereinabove, including Bluetooth and IrDA.
  • the processor of this invention may be a processor already incorporated into the wireless communications device.
  • the receiver of this invention may be any receiver already incorporated into the wireless communications device, such as those described hereinabove, including Bluetooth and IrDA.
  • the wireless communications device may be used in conjunction with a "hands-free" earpiece or headset. In such a case, any directionality-sensing apparatus may be incorporated into the "hands-free" equipment rather than the wireless communications device itself, thus better sensing the direction in which the user's attention is focussed.
