Abstract: Mobile device localization using audio signals is described. In an example, a mobile device is localized by receiving a first audio signal captured by a microphone located at the mobile device and a second audio signal captured from a further microphone. A correlation value between the first audio signal and second audio signal is computed, and this is used to determine whether the mobile device is in proximity to the further microphone. In one example, the mobile device can receive the audio signals from the further microphone and calculate the correlation value. In another example, a server can receive the audio signals from the mobile device and the further microphone and calculate the correlation value. In examples, the further microphone can be a fixed microphone at a predetermined location, or the further microphone can be a microphone located in another mobile device.

Abstract: Methods and apparatus for displaying and interacting with messages are described. Messages are displayed using one of a number of different visualization schemes provided. A user can interact with messages or change the selected visualization scheme using gestures and the mapping of gestures to particular actions is different for different visualization schemes. In an embodiment the messages are received via integrated messaging channels and messages are classified using a number of properties. Each of the visualization schemes has a different way of graphically representing messages and each scheme is adapted to emphasize a different combination of message properties.

Abstract: Methods and apparatus for linking captured images using short range communications or a personal area network are described. In an embodiment, an image capture device is described which detects devices in proximity to the device and stores data identifying the devices and the times when they were in proximity. In another embodiment, a computing-based device is described which uses the data stored by an image capture device to identify sequences of images which were captured by a group of devices in proximity to each other and to present these sequences to a viewer concurrently and in temporal alignment.

Abstract: Proximity-based mobile message delivery is described. In an embodiment, a first user stores a message intended for a second user on a first mobile terminal, while the first mobile terminal is located remote from a second mobile terminal of the second user. Subsequent to this, the first mobile terminal detects that it is now in proximity with the second mobile terminal, and this triggers the first mobile terminal to transmit the message to the second mobile terminal. In embodiments, authentication of the second mobile terminal can be performed before transmitting the message. In another embodiment, a mobile terminal comprises a short-range wireless transceiver that can detect that a further mobile terminal is in proximity, and trigger the transmission of a pre-stored message to the further mobile terminal.

Abstract: A social networking tool is described for use with a display. In an embodiment, the display is permanently located in an enterprise office and facilitates social interaction between users some of whom are remote of the display and at least one of whom is physically local to the display. In an embodiment messages comprising content are received from remote users and the content displayed. One display region for each remote user is displayed concurrently and content received from any particular remote user is only displayed in the display region for that remote user. In an embodiment a user local to the display is able to send a message to a remote user by selecting the appropriate display region. In another embodiment a user local to the display is able to change the position of the display regions on the display and may also annotate the display.

Abstract: A method for wireless discovery of devices is described. In an embodiment, a Wireless Personal Area Networking (WPAN) device advertises its presence to other WPAN devices by transmitting a beacon which includes its identity. The beacon may include a header and/or footer. This message is picked up by other WPAN devices in proximity to the transmitting device and these receiving devices store data identifying the transmitting device. In some embodiments, a database of beacons received by WPAN devices is maintained. This database may be used to associate data which is relevant to transmitting WPAN devices (or to a user thereof) with a WPAN identity.
