     DETAILED DESCRIPTION 
       [0023]    The invention will now be described more fully with reference to the accompanying drawings, in which certain embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout the description. 
         [0024]    There is today an interest in being able to capture additional information of how end users use specific medicament delivery devices. On one hand, this is important information, when it comes to the development of new medicament delivery devices, e.g. high volume injections. On the other hand, the technology can fulfil current market needs, as starting a completely new generation of connected training devices as well as supporting better compliance and adherence. 
         [0025]    Smart sensors, including temperature, motion logging and other ways of tracking physical parameters are today available. In this context, especially by implementation of the new BLE (Bluetooth Low Energy)/Bluetooth Smart technology, data logging systems may be developed, that survive for a very long time period, with a coin size battery. 
         [0026]    The design of a medicament delivery device impacts the functionality and behaviour of a user performing an injection. It is desirable to know how a modification of a design of a medicament delivery device has direct impact on the user&#39; s behaviour and on the performance of the medicament delivery device. 
         [0027]    To visualize and to capture such data may be advantageous for a deeper evaluation of the behaviour of the customers in combination with a specific product. 
         [0028]    A real time, high precision logging system may be provided by use of a sensor device which comprises one or more of the following sensors: a gyroscope, an accelerometer and/or a magnetometer. Using the sensor device for real time visualization, software may be provided, that shows real time visualization on a computer device external of the medicament delivery. The computer device external of the medicament delivery device comprises a display device. Examples of such computer device may be such as a lap-top, a smart mobile device, a tablet or similar. 
         [0029]    Further, a communication device is also provided and configured to transmit data from the logging device to the computer device external of the medicament delivery device. The transmissions of the real time data may be performed wirelessly and/or wired. It can also be desirable to transmit to a remote location. The communication device shall be configured to perform such a transmission using known technologies to transmit to remote locations. 
         [0030]    Sometime it could be desirable to store the data for later analysis. Thus, a memory device may be provided where data received from the logging system may be stored and from which that stored data may be retrieved at a later stage for analysis. The memory device may be a non-volatile memory. 
         [0031]    The system would not only allow motion tracking, but by the smart sensors also allow recording information about the activation status of the medicament delivery device, or even further information, 
         [0032]    This could happen, e.g. by sensing the electromagnetic field of an auto injector spring. The electromagnetic field is for instance different for a spring that has been deployed vs. a non-deployed spring. 
         [0033]    By direct feedback, a system of an app, such as a smartphone application or software, and a medicament delivery device may become a tool providing immediate feedback to analyse a user&#39;s handling behaviour. 
         [0034]      FIG. 1  is a schematic diagram illustrating a medicament delivery device for an embodiment presented herein. 
         [0035]    The medicament delivery device  1  comprises: 
         [0036]    a sensor device  2  configured to detect a motion of the medicament delivery device  1 ; and 
         [0037]    a logging device  3  configured to track user behaviour of the medicament delivery device  1 , which user behaviour is based on a motion detected by the sensor device  2 . 
         [0038]    By motion of the medicament delivery device  1 , movement of the whole device is meant. 
         [0039]    The sensor device  2  may comprise one or more of the following sensors: a magnetometer, a gyroscope, and/or an accelerometer. A magnetometer may by used to detect the position of an auto injector needle of the medicament delivery device  1 . A gyroscope may be used to detect the position of the medicament delivery device  1 . An accelerometer may be used to detect movement in a direction. By use of a combination of a gyroscope and three accelerometers, a high precision tracking may be provided. 
         [0040]    The medicament delivery device  1  may further comprise a memory device such as a non-volatile memory to store data from the sensor device  2  and/or from the logging device  3 . The non-volatile memory may e.g. be a read-only memory, flash memory, ferroelectric RAM (F-RAM), most types of magnetic computer storage devices (e.g. hard disks, floppy disks, and magnetic tape), optical discs. The non-volatile memory may be removable, to be inserted into a reader of an external device. The medicament delivery device  1  may further be provided with a contact interface, allowing stored data to be uploaded to an external device through a cable connection. Further, the medicament delivery device  1  may be provided with a communication device allowing real data and/or stored data to be uploaded to the external device. The communication device is configured to wirelessly and/or wired transmit real time data from the logging device or to transmit stored data from the memory device. The communication device may be provided with e.g. wi-fi, Bluetooth or BLE. 
         [0041]    The logging device  3  may be configured to start tracking user behaviour when the medicament delivery device  1  is removed from a transportation box or when a protective cap is removed from the medicament delivery device. The user behaviour data will be stored in the memory device e.g. in a non-volatile memory in the medicament delivery device. A user will in this case not need to remember to start any initiations, or try to figure out how to connect the medicament delivery device to an external device, wired or wirelessly. I.e. the user does not have to do anything different than he does with a conventional device. The device may automatically log, e.g. within a time period of more than a week from taking the product out of the box, the use of the device and behaviour of the user. To start tracking when the device is removed from the transportation box or when the protective cap is removed from the medicament delivery device, a disconnected battery may be included in the device. When the device is removed from the box or when the protective cap is removed from the medicament delivery device, an insulation sheet may be removed from between the battery and a contact pad. 
         [0042]    The medicament delivery device  1  may be an actual delivery device  1  for delivery of a medicament. By tracking the user behaviour, it is possible to later identify if a user have been using the medicament delivery device  1  in a correct manner or not. By transmitting real time data to an external device, visualization of direct feedback may be provided. 
         [0043]    The medicament delivery device may be a mock-up demo device for human factors study or for training. 
         [0044]    The medicament delivery device may be provided with both a data storage as well as a real time data transmitter. By being directly connected via e.g. Bluetooth to a tablet computer to sense real time data, human factor/patient study in real time can be made to see what a patient does with the device/how he handles it. With a data storage, the same data may be provided for further evaluation in the future, by comparison to future data. 
         [0045]    For human factors study, a multi-device may be provided, that would allow tracking patients&#39; behaviour with different devices or devices that have been equipped with modified parts (e.g. different activation button, different surface of device etc,). 
         [0046]    For training, a patient may use a medicament delivery training device at home. Once he returns the device to a study organizer, the organizer will be able to evaluate the data, e.g. together with the patient, to understand, if the patient had any issues and if he complied with the handling instructions. 
         [0047]      FIG. 2  is a flow chart illustrating a method for an embodiment presented herein. 
         [0048]    The method for user behaviour tracking of a medicament delivery device  1 , comprises the steps of: 
         [0049]    detecting  10  a motion of the medicament delivery device  2 ; and 
         [0050]    tracking  11  a user behaviour of the medicament delivery device  1  based on the detected motion. 
         [0051]      FIG. 3  is a schematic diagram illustrating a medicament delivery system for an embodiment presented herein. 
         [0052]    The medicament delivery system comprises: 
         [0053]    a medicament delivery device  1 , a computer device external of the medicament delivery device  1  having a display device  4 , 
         [0054]    the medicament delivery device comprises:
       a sensor device  2  configured to detect a motion of the medicament delivery device  1 ;   a logging device  3  configured to track user behaviour of the medicament delivery device  1 , which user behaviour is based on a motion detected by the sensor device  2 ; and   communication device configured to transmit wirelessly or wired real time data from the logging device or data stored in a memory device from the logging device to the display device  4 .       
 
         [0058]    The invention has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the invention, as defined by the appended patent claims.
