This invention relates to a device that can be controlled by the movement of a user. It is increasing common for people to possess a smartphone, or other mobile device, that can be used for a variety of functions. These devices can be carried by the user and used whilst the user is moving around. The device may also communicate with accessories carried by the user, such as (i) sensors attached to another device located on the user, perhaps in the form of a wristband that can sense movement and other data about the user; or (ii) headphones so that the device can transmit audio to the user's ears.

The functions on the device that are used by the user may change depending on the location and activity of the user. For example, when the user is on a train, the user may use the smartphone to check emails or browse websites, however when the user is walking in the street the user may play music to the headphones from the device or use a mapping function in combination with the device's satellite positioning sensor to navigate to a given location. The control of those functions may be problematic depending on the activity that the user is performing. If the device is in the user's pocket, and the user is walking, it can be difficult to interact with one of the functions that the device may be performing at that time. For instance, the user may want to switch to the next song in an album, or pause the audio. Also, the user can become distracted by operating the device in situations where the user's concentration should be focused on the environment around them. For instance, the user may be looking at the screen of the device operating the device, whilst walking along the street, when the user's concentration should be focused on traffic around them.

Various control mechanisms are in use to control a device which can be used to help solve the problems associated with controlling the device whilst the user is active. For instance, the user's voice can be used to control the device, or buttons can be provided on an accessory, such as the headphones. However, these control mechanisms may still not provide an acceptable level of control depending on the user's activity. For instance, initiating voice control generally requires direct user interaction with the device and may not be suitable in noisy environments or whilst the user is unable to speak clearly. The user may also find it difficult to use the buttons because the size of the device that they are present on is small or the way they function means that they are not easily used in all situations. It is therefore desirable for there to be improved ways for a user to interact with a device.

The present invention will now be described by way of example with reference to the accompanying drawings. In the drawings: Figure 1 shows a schematic diagram of a device and accompanying sensor devices.

The following description is presented to enable any person skilled in the art to make and use the invention, and is provided in the context of a particular application. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art.

The general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

Figure 1 shows an example device that can be controlled in dependence on the movement of one or more other devices that are connected to the example device. The example device may be a mobile device 10. The mobile device may be connected to one or more sensor devices 1 1 , 12. In figure 1 , two sensor devices are shown but it will be appreciated that only one or more than two may be present and in the following description reference to one sensor device may equally be applied to multiple sensor devices. The mobile device may be configured to implement a set of predefined functions. These functions may be initiated, selected and/or interacted with, or otherwise controlled, by a user. The user may use a user interface present on the device to control those functions. The mobile device is configured to receive user pose data and/or sensor movement data from the one or more sensor devices 1 1 , 12. The mobile device is configured to modify the implementation of one or more of the set of predefined functions in response to at least one of the user pose data and sensor movement data. For instance, the sensor movement data may be indicative of the user removing the sensor devices from their ears and so the mobile device may pause the streaming of audio data to the sensor devices.

The mobile device 10 of figure 1 comprises a housing 20. Within the housing are a battery 21 , a processing section 22 and a memory 28. The mobile device 10 also comprises a user interface constituted by a display 23 and a series of user-actuable switches 24 which are exposed on the exterior of the housing. The display and switches could be combined into a touchscreen device. The mobile device 10 comprises a first wireless communication device 25 for communicating with the sensor devices 1 1 , 12. The mobile device 10 may use the first wireless communication device 25 to also communicate with other devices. The wireless communication devices may be known as transceivers.

The battery 21 stores energy for powering the other components.

The mobile device 10 may be capable of performing a plurality of functions. These functions may be implemented and controlled by the processing section 22. The processing section could perform its functions using dedicated hardware, using a general purpose processor executing software code, or using a combination of the two. A processor 26 executes software code stored in a non-transient way in software memory 27 in order to perform its functions. The processing section 22 can read/write data from/to memory 28.

The mobile device 10 could include other interfaces and sensors. For example, it could include any one or more of:

a satellite positioning sensor which could provide information on the location and/or altitude of the mobile device 10 to the processing section 22; a wired or wireless communication interface for allowing communication between the processing section 22 and a remote device, for example a cellular telephony interface, a Wi-Fi (IEEE 802.1 1 ) interface, a Bluetooth interface or a USB (universal serial bus) interface;

an environmental sensor such as a temperature sensor or a humidity sensor, which could provide information on the environment around the mobile device 10 to the processing section 22;

a loudspeaker, by which alerts could be provided to a user; and

a microphone, which in combination with the loudspeaker could permit the mobile device 10 to function as a telephone.

It will be appreciated that, although the device 10 is described as a mobile device in many of the examples given herein, the device 10 could also be a device that is not easily portable by the user, such as a desktop computer.

In figure 1 , the sensor devices 1 1 , 12 are each in the form of an earpiece. The sensor devices 1 1 , 12 may each comprise accelerometers 30, 31 , a local battery 32, 33, and a wireless communication device 34, 35 for communicating with the first wireless communication device 25 of the mobile device 10. Alternatively, only one sensor device 1 1 may be present, or first sensor device 1 1 may use second wireless communication device 34 to communicate with the first wireless communication device 25 of the mobile device, and the second sensor device 12 may communicate with the first sensor device 1 1 . The first sensor device 1 1 may communicate with the mobile device 10 on behalf of second sensor device 12. First sensor device 1 1 and second sensor device 12 may be connected together by wire rather than by wireless connection. The sensor devices may communicate with the mobile device 10 by a wired connection rather than by wireless connection. The sensor devices 1 1 , 12 could include other sensors. For example, the sensor devices 1 1 , 12 could include gyroscopic sensors, for example one or more rate gyro sensors.

Collectively, the accelerometers 30, 31 are preferably capable of sensing acceleration in any direction. To that end the accelerometers could be provided by set of three integrated or discrete accelerometers arranged to sense acceleration along respective orthogonal axes. Alternatively, the accelerometers could be arranged to sense acceleration along one or more specific axes that are orientated in a predetermined fashion with respect to the user's body: for example there could be only a single accelerometer, which could be arranged with respect to the user's body so as to sense acceleration in a vertical or substantially vertical direction when the user is walking or running; or there could be only two accelerometers, which could be arranged with respect to the user's body so as to sense acceleration in a vertical or substantially vertical direction and in a lateral or substantially lateral direction when the user is walking or running. In a preferred example the accelerometers provide a time series of acceleration values. The accelerometers could be mechanical accelerometers. Preferably the accelerometers measure acceleration directly.

The earpieces 1 1 and 12 can also each include a loudspeaker 36, 37. The processing unit 22 of the mobile device 10 may be capable of replaying audio from data stored in the memory 28 to the loudspeaker(s) 36, 37 via a wireless communication link between transceivers 25 and 34, 35. Alternatively the earpiece itself may be capable of replaying audio through the loudspeaker, using an audio processor integrated in the earpiece. The mobile device 10 may transfer an audio file stored in memory 28 to the earpiece for processing by the audio processor integrated in the earpiece. The ear piece may attach to the user's ear by a formation 40, 41 of its housing that wraps around the ear of a wearer and/or by virtue of an ear bud 38, 39 that can be inserted into and lodge in the ear canal of the wearer. These mechanisms allow the earpiece 1 1 , 12 to be attached firmly to the user's head, so that they move with the user's head. This allows the accelerometers 30, 31 in the earpiece to gather accurate data about the motion of the user's head. It has been found that mounting the accelerometers in an earpiece is a particularly convenient approach since it provides good data about the user's gait and because many users find an earpiece to be a convenient form in which to carry a device attached firmly to their body. Furthermore, when the earpiece can also replay audio, for example, music, to a user, the user can enjoy that audio whilst exercising.

The sensor devices 1 1 , 12 can each transmit sensed data using their respective wireless communication devices 34, 35 to the first wireless communication device 25 of the mobile device 10. The sensor device 1 1 , 12 may be capable of processing the outputs of the accelerometers 30, 31 and, if present, gyroscopic sensors 30, 31 . The sensor device 1 1 , 12 may incorporate processing sections that are similar in function to the processing section 22 of mobile device 10. The processing sections in sensor devices 1 1 , 12 may have a lower processing capability to reduce power consumption. The processing section of the sensors may undertake the processing of the outputs of the accelerometers 30, 31 and, if present gyroscopic sensors 30, 31 to detect elements of interest in the live acceleration being sensed from the motion of a user. The current pose of the user may be detected from the live acceleration data. An example set of methods and equipment of processing acceleration data and, if present, gyroscopic data to determine the current pose of the user is described in copending UK patent application no. GB1422847.2. Where permitted, GB1422847.2 is herein incorporated by reference. These methods and equipment involve the sensing of accelerations at a series of moments over time a time-series of accelerations is produced. Accelerations sensed most recently (e.g. during a window extending back between 1 and 10 seconds from the latest sensed acceleration) can be compared with one or both of: (i) specific acceleration features derived from the analysis of previously logged data for the same and/or other users and identified as correlating with certain gait artefacts; and (ii) comparisons between assessments of the recently sensed accelerations according to one or more metrics and predetermined thresholds for those assessments.

The live acceleration data may also be processed to generalise the acceleration of the sensor to reduce the data rate of the acceleration data. The live acceleration data may be processed to produce time-series acceleration data with a greater time between each acceleration data value. The acceleration data may form part of the sensor motion data that is derived by the sensor. The orientation data provided by the gyroscopic sensor may also be processed to derive sensor motion data. The user pose data and/or the sensor motion data can be transmitted by the sensor to the mobile device 10. The user pose data and/or sensor motion data may be transmitted continuously, periodically or when a change in the data is detected. For instance, the sensor device may detect that there has been a change in the user's pose and send an update to the user pose data at that point.

The user pose data may indicate the user's current pose is one of the following: - sitting;

- standing;

- walking;

- running;

- lying down;

- sleeping;

- cycling; and/or

- swimming. The sensor device may be capable of detecting that the user's current pose is one of a subset of those poses listed above.

The user pose data may also indicate the attitude of a user's head, or changes thereof. The sensor device may keep an estimate of the current position of the user's head and update that estimate when acceleration is sensed. The sensor device can then provide the mobile device with user pose data that indicates the current attitude of their head about either or both axes.

The operation of the mobile device 10 in dependence on the user pose data and/or sensor movement data will now be described using a number of examples. It will be appreciated that these examples may be generalised and/or may be used in any combination with each other.
