Detailed Description of Embodiments of the Invention

It will be appreciated that embodiments of the present invention can be realised in the form of hardware, software or a combination of hardware and software. Any such software may be stored in the form of volatile or non-volatile storage such as, for example, a storage device like a ROM, whether erasable or rewritable or not, or in the form of memory such as, for example, RAM, memory chips, device or integrated circuits or on an optically or magnetically readable medium such as, for example, a CD, DVD, magnetic disk or magnetic tape. It will be appreciated that the storage devices and storage media are embodiments of machine-readable storage that are suitable for storing a program or programs that, when executed, implement embodiments of the present invention. Accordingly, embodiments provide a program comprising code for implementing a system or method as claimed in any preceding claim and a machine readable storage storing such a program. Still further, embodiments of the present invention may be conveyed electronically via any medium such as a communication signal carried over a wired or wireless connection and embodiments suitably encompass the same.

Referring to figure 1 there is illustrated a schematic block diagram of circuitry of wearable recording device 100 according to an embodiment of the present invention. The circuitry of the wearable recording device 100 includes a memory unit 102 that may comprise both a Read Only Memory (ROM) and a Random Access Memory (RAM) as will be apparent to a person skilled in the art. There is an audio unit comprising a microphone 104 arranged for outputting audio data in response to a received audio signal, such as speech from a user of the device. In other embodiments, the microphone may be external to the device, and the device may comprise an audio unit for receiving the audio data from the external microphone. The audio unit may be a wired or wireless communication unit. The audio data may comprise an electrical signal. The circuitry for the wearable recording device 100 also includes a user interface unit 106 for receiving input commands from a user. There is a control unit 108 arranged, responsive to a predetermined input command from the user interface unit 106, to store in the memory unit 102, audio data indicative of the output by the microphone 104.

The circuitry of the wearable recording device 100 also Includes a speaker port 110 for outputting the stored audio data. The memory unit 102, microphone 104, user Interface unit 106, and speaker port 110 are coupled to the control unit 108. Also, the control unit 108 Is arranged to automatically control the memory unit 102 to send an indication of the stored audio data to the speaker port 110 after expiration of a predetermined time interval. Typically, the indication of the stored audio data comprises the stored audio data and the speaker port is arranged to transmit a signal (i.e. an audio signal) representing the stored audio data. Thus, a pre-recorded message stored in the memory unit 102 is automatically played to the user after the expiration of the predetermined time interval.

In this embodiment the speaker port 110 is a short range radio transmitter with an antenna 112 for short range coitimunication with an earphone with a radio receiver. However, in other embodiments the speaker port 110 may be a driver coupled to a speaker integrated into the device 100 or a driver coupled to a socket for engaging with a jack-plug or any combinations of the integrated speaker, socket and short range radio transmitter.

In this embodiment there is a removable and re-chargeable battery 120 coupled to the memory unit 102 and control unit 108 powered by the battery 120. In other embodiments the speaker port and/or the user interface unit may also be powered by the battery 120.

In one embodiment the predetermined time interval is one of a plurality of predetermined time intervals and the control unit 108 is arranged to automatically control the memory unit 102 to send the indication of the stored audio data after expiration of each one of the plurality of predetermined time intervals. In one embodiment the predetermined time intervals are incrementally smaller predetermined time intervals and the control unit 108 is arranged to automatically control the memory unit 102 to send the indication of the stored audio data after expiration of each one of predetermined time intervals. Thus, a pre-recorded message stored in the memory unit 102 is automatically played to the user after the expiration of each of the predetermined time intervals.

The control unit 108 can be arranged to cause the memory unit 102 to store the audio data in response to a first user input command from the user interface unit 106, and to stop storing the audio data in the memory unit 102 in response to a second user input command from the user interface unit 106. The control unit 108 can also be arranged to cause the memory unit 102 to send the stored audio data to the speaker port 110 in response to a third user input command from the user interface unit 106. In some embodiments the control unit 108 can also be arranged to cause the memory unit 102 to and skip back (rewind) and then re-send the stored audio data to the speaker port 110 in response to the fourth user input command from the user interface unit 106.

In some embodiments, in response to another user input command from the user interface unit 106, the control unit 108 is arranged to control the memory unit 102 to stop sending the indication of the stored audio data at the predetermined time intervals.

In some embodiment the control unit 108 is arranged to receive a further input command, from the user interface unit 104, to thereby allow a user to set the predetermined time interval or intervals.

Referring to figure 2 there is illustrated an upper perspective view of a wearable recording device 200 according to an embodiment of the present invention. The wearable recording device 200 includes a housing 202 that houses the circuitry of the wearable recording device 100. In one embodiment the device 200 includes an annular biased actuator 204 rotatable about an axis relative to a housing 202. The device comprises a push button actuator 206. In some embodiments the push button actuator is coaxial with, and surrounded by, the annular biased actuator 204. In this embodiment the push button actuator 206 has a concave surface to reduce the possibility of accidental actuation. Furthermore, the push button actuator 206 and annular biased actuator 204 are actuators of the user interface unit 106 as will be apparent to a person skilled in the art. It will be realised, however, that in some embodiments the device 200 only comprises the push button actuator 204.

In this embodiment the wearable recording device 200 includes a microphone aperture 210 in the annular biased actuator 204. The microphone aperture 210 is aligned with the audio unit comprising the microphone 104 that is housed in the housing 202. In other embodiments, the microphone may be external to the device, and the device may comprise an audio unit for receiving the audio data from the external microphone. The audio unit may be a wired or wireless communication unit. The audio data may comprise an electrical signal. There is also an actuator position indicator in the form of a radial groove 212 formed in the annular biased actuator 204 and located on the push button actuator 206 are diametrically opposed play 214 and skip back (rewind) 216 indicators.

In this embodiment the wearable recording device 200 includes a socket 218, which is part of the speaker port 100, mounted in the housing 202 for engaging with a jack-plug. In other embodiments, as a replacement for or in addition to the socket 218, there may be a speaker integrated into the device 200 or a short range radio transmitter that is part of the speaker port 100.

As illustrated in this embodiment, the wearable recording device 200 includes a clip 220, typically a resilient clip, for attaching the wearable recording device 200 to clothing or apparel of a user.

In operation, in some embodiments, when a user presses and holds the push button actuator 206 in an actuated state the control unit 108 determines that this actuation corresponds to the first user input command. As a result the device 200 starts recording and therefore stores in the memory unit 102, audio data Indicative of the audio data output by the microphone 104. The first user input command may alternatively correspond to a single momentary push of the push button actuator 206.

In some embodiments, when the push button actuator 206 is released from the actuated state the control unit 108 determines that this actuation corresponds to the second user input command. As a result, the control unit 108 controls the memory unit 102 to stop storing (stop recording) the audio data. In another embodiment, the second user input command may correspond to a first predetermined number of momentary pushes of the push of the push button actuator 206, such as two momentary pushes .

Referring to figure 3 there is illustrated a plan view of the wearable recording device of 200 when the annular biased actuator 204 is in a neutral operational state. In this illustration the annular biased actuator 204 can be seen to be in the neutral operational state because the radial grove 212 is equidistant from the diametrically opposed play 214 and skip back (rewind) 216 indicators. Also illustrated is a lanyard 310 captured by the clip 220 to allow the wearable recording device of 200 to be suspended from the neck of a user.

Referring to figure 4 there is illustrated a plan view of the wearable recording device of 200 when the annular biased actuator 204 is in a first operational state. This first operational state is achieved, in some embodiments, by a user rotating the annular biased actuator 204 in a first direction D1 so that the radial groove moves towards the play indicator 214. As soon as the user releases the annular biased actuator 204 it will return to the neutral operational state as will be apparent to a person skilled in the art. When the user rotates the annular biased actuator 204 in the first direction D1 the third user input command from the user interface unit 106 is generated. In response, the control unit 108 is arranged to control the memory unit 102 to send the stored audio data to the speaker port speaker port 110 which thereby transmits a signal representing the stored audio data. In other embodiments, the third user input command corresponds to a second predetermined number of momentary pushes of the push of the push button actuator 206, such as three momentary pushes.

Referring to figure 5 there is illustrated a plan view of the wearable recording device of 200 when the annular biased actuator 204 is in a second operational state. This second operational state is achieved by rotating the annular biased actuator 204 in a second direction D2 so that the radial groove moves towards the skip back (rewind) 216 indicator. Again, as soon as the user releases the annular biased actuator 204 it will return to the neutral operational state as will be apparent to a person skilled in the art.

When the user rotates the annular biased actuator 204 in the second direction D2 the fourth user input command from the user interface unit 106 is generated. In response, the control unit 108 is arranged to control the memory unit 102 to skip back (rewind) and then re-send the stored audio data to the speaker port 110. In some embodiments, the fourth user input command corresponds to a third predetermined number of momentary pushes of the push of the push button actuator 206, such as four momentary pushes.

Although not specifically illustrated, in some embodiments the user interface unit may include one or more further actuators. One of the further actuators when actuated may generate another user input command from the user interface unit 106. In response, the control unit 108 is arranged to control the memory unit 102 to stop sending the stored audio data to the speaker port 110. When another one of the further actuators is actuated it may generate a further user input command or commands from the user interface unit 106. In response, the control unit 108 is arranged to adjust the predetermined time interval based on the further user input command or commands.

Referring to figure 6 there is illustrated a lower perspective view of the wearable recording device 200 according to an embodiment of the present invention. The wearable recording device 200 includes a planar surface 610 at a free end of the clip 220. This planar surface 610 provides for a name tag mount that may be used to record the user's name and address.

Referring to figure 7 there is illustrated a plan view of the wearable recording device 700 according to another embodiment of the present invention. The wearable recording device 700 includes a housing 702 that houses the circuitry of the wearable recording device 100. The device 700 includes a single push button actuator 704 biased to a neutral position and is part of the user interface unit 106 as will be apparent to a person skilled in the art.

In this embodiment the wearable recording device 700 includes a socket 718, which is part of the speaker port 100, mounted in the housing 702 for engaging with a jack-plug. In other embodiments, as a replacement for or in addition to the socket 718, there may be a speaker integrated into the device 7 00 or a short range radio transmitter that is part of the speaker port 100. Also shown is a lanyard 722 captured by a clip (not shown) to allow the wearable recording device of 700 to be suspended from the neck of a user.

In this embodiment the wearable recording device 700 includes a microphone aperture 710 in the push button actuator 704. The microphone aperture 710 is aligned with the microphone 104 that is housed in the housing 702. In other embodiments, the microphone may be external to the device, and the device may comprise an audio unit for receiving the audio data from the external microphone. The audio unit may be a wired or wireless communication unit. The audio data may comprise an electrical signal. Displayed on the push button actuator 704 are function indicators which are a record indicator 706, a stop recording indicator 708, a play recording indicator 714 and a skip back (rewind) indicator 716. The push button actuator 704 is arranged to pivot at its centre so that switched aligned with the function indicators 706, 708, 714 and 716 may be actuated by the appropriate pressure applied to the push button actuator 704.

In operation, in this embodiment when a user presses the push button actuator 704 at a location proximal to the record indicator 706 the control unit 108 determines that this actuation corresponds to the first user input command. As a result the device 700 starts recording and therefore stores in the memory unit 102, audio data indicative of the audio data output by the microphone 104. When a user presses the push button actuator 704 at a location proximal to the stop recording indicator 708 the control unit 108 determines that this actuation corresponds to the second user input command. As a result, the control unit 108 controls the memory unit 102 to stop storing (stop recording) the audio data.

When the user presses the push button actuator 704 at a location proximal to the play recording indicator 714 the third user input command from the user interface unit 106 is generated. In response, the control unit 108 is arranged to control the memory unit 102 to send the stored audio data to the speaker port speaker port 110 which thereby outputs a signal representing the stored audio data. When the user presses the push button actuator 704 at a location proximal to the skip back (rewind) indicator 716 the fourth user input command from the user interface unit 106 is generated. In response, the control unit 108 is arranged to control the memory unit 102 to skip back (rewind) and then re-send the stored audio data to the speaker port 110.

Although not specifically illustrated, in some embodiments the user interface unit may include one or more further actuators. One of the further actuators when actuated may generate another user input command from the user interface unit 106. In response, the control unit 108 is arranged to control the memory unit 102 to stop sending the stored audio data to the speaker port 110. When another one of the further actuators is actuated it may generate a further user input command or commands from the user interface unit 106. In response, the control unit 108 is arranged to adjust the predetermined time interval based on the further user input command or commands.

It will also be appreciated be a person skilled in the art that the in some embodiments push button actuator 704 may be replace with a touch sanative pad such as a touch screen.

Referring to figure 8 there is illustrated a plan view of the wearable recording device 800 according to another embodiment of the present invention. The wearable recording device 800 includes a housing 802 that houses the circuitry of the wearable recording device 100. The device 800 includes a push button actuator 804 and is part of the user interface unit 106 as will be apparent to a person skilled in the art.

In this embodiment the wearable recording device 800 includes a socket 818, which is part of the speaker port 100, mounted in the housing 802 for engaging with a jack-plug. In other embodiments, as a replacement for or in addition to the socket 818, there may be a speaker integrated into the device 800 or a short range radio transmitter that is part of the speaker port 100. Also shown is a lanyard 822 captured by a clip (not shown) to allow the wearable recording device of 700 to be suspended from the neck of a user.

In this embodiment the wearable recording device 800 includes a microphone aperture 810 In the push button actuator 804. The microphone aperture 810 is aligned with the microphone 104 that is housed in the housing 802. In other embodiments, the microphone may be external to the device, and the device may comprise an audio unit for receiving the audio data from the external microphone. The audio unit may be a wired or wireless communication unit. The audio data may comprise an electrical signal.

In operation. In this embodiment when a user presses the push button actuator 804 once within a time window the control unit 108 determines that this actuation corresponds to the first user input command. As a result the device 800 starts recording and therefore stores in the memory unit 102, audio data Indicative of the audio data output by the microphone 104. When a user presses the push button actuator 804 twice within the time window the control unit 108 determines that this actuation corresponds to the second user input command. As a result, the control unit 108 controls the memory unit 102 to stop storing (stop recording) the audio data.

When the user presses the push button actuator 804 three times within the time window the third user input command from the user interface unit 106 is generated. In response, the control unit 108 is arranged to control the memory unit 102 to send the stored audio data to the speaker port speaker port 110 which thereby transmits a signal representing the stored audio data. When the user presses the push button actuator 804 four times within the time window the fourth user input command from the user interface unit 106 is generated. In response, the control unit 108 is arranged to control the memory unit 102 to skip back (rewind) and then re-send the stored audio data to the speaker port 110.

Again, although not specifically illustrated, in some embodiments the user interface unit may include one or more further actuators. One of the further actuators when actuated may generate another user input command from the user interface unit 106. In response, the control unit 108 is arranged to control the memory unit 102 to stop sending the stored audio data to the speaker port 110. When another one of the further actuators is actuated it may generate a further user input command or commands from the user interface unit 106. In response, the control unit 108 is arranged to adjust the predetermined time interval based on the further user input command or commands.

Referring to figure 9 there is a flow chart illustrating a method 900 of playing a message stored on in a memory unit of a wearable recording device according to an embodiment of the present invention. By way of illustration only the method 900 will be described with reference to the circuitry of wearable recording device 100 and is thus primarily controlled by the control unit 108.

At a decision block 910 the method 900 waits to receive an input command from the user interface unit 106. Once the command is received, a storing block 920 provides for s storing, in the memory unit 102, audio data indicative of the audio data output by the microphone 104. Next at a time interval test block 930 the control unit 108 determines if a time predetermined interval has expired. When the time interval has expired a block 940 provides for automatically sending from the memory unit 102 an indication of the stored audio data to the speaker port 110. Thus, as will be apparent to a person skilled in the art the automatically sending is performed after an expiration of the predetermined time interval.

At an end decision block 950 it is determined if a user has actuated the user interface 106 to indicate that the user no longer wishes to receive, via the speaker port 110 further identical indications of the stored audio data. If it is determined that the user no longer wishes to receive, via the speaker port 110 further identical indications of the stored audio data then the method 900 returns to the decision block 910. Otherwise, the method repeats blocks 930 to 950. Thus, when blocks 930 to 950 are repeated the predetermined time interval becomes one of a plurality of predetermined time intervals. Furthermore, when block 940 is repeated the automatically sending is repeated thereby sending the indication of the stored audio data after expiration of each one of the plurality of predetermined time intervals. This automatically sending is repeated until it is determined, at end decision block 950, that the user no longer wishes to receive further identical indications of the stored audio data.

In some embodiments the time intervals are incrementally smaller predetermined time intervals thereby assisting in reminding the user to act on the indication of the stored audio data. Also, the indication of the stored audio data may comprise the stored audio data. Consequently, the automatically sending comprises the speaker port outputting a signal representing the stored audio data so that a recorded audio message can be played to the user.

In some embodiments the input command is a first input command of one of a plurality of input commands including a second input command for stopping storing, in the memory unit 102, the audio data. Typically, the method 900 determines the first and second user input commands based on a number of actuations of the user within a time window. Also, the plurality of input commands may include a third user input command for causing the memory unit 102 to send the stored audio data to the speaker port 110. Typically, the method 900 determines the third user input command based on a number of actuations of the user within the time window.
