Definitions

  • the present invention relates to aerosol generation devices and the use of gestures to operate such devices.
  • An aerosol generation device such as an electronic cigarette is typically easily operated, for example by providing negative pressure to a mouthpiece, i.e. inhaling, or by pressing a button.
  • the ease with which the aerosol generation device may be operated can be beneficial to a user, but there may be situations in which a higher level of security is desired, such as when the user is around children. Accidental usage may be avoided by increasing the security level of the device.
  • An aspect of the invention provides an aerosol generation device, comprising: a sensor that comprises a capacitive unit having a plurality of capacitive cells configured to detect user gestures; locking control circuitry configured to lock or unlock the aerosol generation device upon detection of a first gesture by the sensor; and lock enable control circuitry configured to enable or disable the locking control circuitry upon detection of a second gesture by the sensor, wherein the sensor is configured to remain active for the detection of user gestures irrespective of the lock state of the aerosol generation device, and irrespective of whether the lock enable control circuitry is enabled or disabled.
  • locking control circuity and lock enable control circuity in the device advantageously provides flexible levels of device security which can be adapted based on user preference and a particular user situation. If the locking control circuity is enabled, a locked device can be unlocked in order to use it, and an unlocked device can be locked in order to prevent accidental input or use, for example by a child. Alternatively, if the locking control circuitry is disabled, the device can be used freely. A user may prefer to disable the locking control circuitry for convenience during a period of frequent use in which the device is unlikely to be tampered with. Advantageously, this can be achieved using a single sensor that can detect both the first and second gestures.
  • the sensor is preferably arranged to be continuously monitoring user gestures whenever power is supplied from a power source.
  • the sensor is used for unlocking the device and additionally for enabling or disabling the locking control functionality. Thus, the sensor itself cannot be locked or disabled.
  • the sensor of the aerosol generation device is configured to detect user gestures.
  • the particular type or types of sensor used may depend on the type of user gesture.
  • the user gesture may involve motion, touch, other forms of input, or any combination of these.
  • the sensor comprises a capacitive unit having a plurality of capacitive cells, preferably positioned on a surface of the outer body of the aerosol generation device.
  • the sensor may comprise one or more buttons which can be used for touch input.
  • a capacitive unit having a plurality of capacitive cells as a sensor can advantageously be used to detect a variety of different touch inputs such as tapping, touching and holding, swiping, or any combination of these in sequence.
  • the capacitive cells may be arranged linearly within the capacitive unit. This advantageously simplifies the available user gestures.
  • a user gesture can beneficially be entered in a natural way without a high level of precision.
  • the first and second gestures can be programmed to comprise any form of user gesture or sequence of user gestures.
  • the first or second gesture comprises: holding a first capacitive cell for a predetermined time period; and swiping along a length of the plurality of capacitive cells.
  • the locking control circuitry is configured to lock or unlock the aerosol generation device upon detection of a first or second gesture by the sensor.
  • a touch and hold gesture followed by a swipe gesture is advantageously difficult to input inadvertently whilst each component of the first or second gesture is a natural gesture for a user to perform. This beneficially results in a gesture which is easy to perform with a low risk of accidental input. Therefore the user can easily change the lock state on demand.
  • the first or second gesture comprises: holding a first capacitive cell and a second capacitive cell for a predetermined time period; and swiping along a length of the plurality of capacitive cells.
  • this typically requires two hands, or the careful placement of adjacent digits on a single hand, and therefore adds security to the gesture.
  • the first or second gesture includes one or more swipe actions.
  • Each of the one or more swipe actions may comprise swiping along the length of the plurality of capacitive cells.
  • Each of the one or more swipe actions may be performed in any direction.
  • each of the one or more swipe actions may be performed in the same direction, or in alternating directions, or in a predefined sequence of directions.
  • the first or second gesture comprises: swiping in a first direction along the length of the plurality of capacitive cells; and swiping in a second direction along the length of the plurality of capacitive cells.
  • the first and second direction may be substantially the same direction.
  • the second direction is substantially opposite to the first direction.
  • the first direction may be left to right, or top to bottom, and the second direction may be right to left, or bottom to top.
  • the absolute direction of the swipe will depend on the orientation of the aerosol generation device.
  • the sensor is preferably configured to detect the relative difference between the first and second directions.
  • the senor may be configured to detect the second gesture when the first direction is from a first end of the capacitive unit to a second end of the capacitive unit and when the second direction is from the second end to the first end.
  • the sensor may also be configured to detect the second gesture when the first direction is from the second end to the first end and the second direction is from the first end to the second end. This may beneficially provide flexibility to the user, as the user would not have to remember to start the gesture at a particular end.
  • the senor may be configured to only detect the second gesture when the first direction is a particular direction such as from the first end of the capacitive unit to the second end of the capacitive unit. This more limited detection by the user may beneficially help to avoid accidental input.
  • the second gesture comprises elements which are easy to input, but the particular sequence of individual gestures is difficult to perform by accident. Accordingly, the second gesture also beneficially results in a gesture which is easy to input with a low risk of accidental input. Therefore the user can easily enable or disable the locking control circuitry on demand.
  • the device may be configured to provide feedback to the user upon initial recognition of, during, or after completion of, one or more user gestures.
  • the aerosol generation device includes a feedback unit configured to provide sensory feedback to a user.
  • the feedback unit optionally comprises a haptic unit, a photic unit, an aural unit, or a combination of these.
  • the feedback unit may provide feedback using vibrations, lights, or sounds. This advantageously can communicate information to the user about the success, failure, duration, or other status of the user gesture.
  • the feedback unit may be activated by the locking control circuitry upon detection of the first gesture. This may provide confirmation to the user that the aerosol generation device has successfully been locked or unlocked.
  • the feedback unit may be activated by the lock enable control circuitry upon detection of the second gesture in order to communicate to the user that the locking control circuitry has been enabled or disabled.
  • Feedback may also be provided to the user in the process of entering the first and/or second gestures.
  • this provides feedback to the user which allows the user to re-enter a gesture, stop entering a gesture, start entering a gesture, perform the next gesture in a sequence, or otherwise interact with the device according to the received sensory feedback.
  • the present approach can assist the user in performing a technical task, which is the locking or unlocking of the aerosol generation device or the enabling/disabling of the locking control circuitry.
  • the feedback can guide a user through this human-machine interaction while providing the first or second gesture. If the user attempts to complete the first or second gesture but does not receive any sensory feedback they can understand that there was an error in the detection or performance of the gesture. The absence of expected feedback can therefore guide the user to re-enter the gesture.
  • the aerosol generation device is connected to an electronic device, and the lock enable control circuitry is further configured to enable or disable the locking control circuitry upon receipt of a control command sent to the aerosol generation device by the connected electronic device.
  • the electronic device which may be a smartphone for example, allows the locking control circuitry to be enabled or disabled remotely. This advantageously provides additional flexibility for the user. However, it does not replace the direct control that the user has using the sensor that is located on the device.
  • the lock enable control circuitry is configured to enable or disable the locking control circuitry.
  • the lock enable control circuitry is further configured to unlock the aerosol generation device when the locking control circuitry is disabled. Accordingly, if the locking control circuitry is enabled and the device is locked, the lock enable control circuitry may be configured to disable the locking control circuitry and unlock the aerosol generation device upon detection of the second gesture. Alternatively, if the locking control circuitry is enabled and the device is unlocked, the lock enable control circuitry may be configured to disable the locking control circuitry and leave the aerosol generation device unlocked. This beneficially allows the device to be used freely when desired.
  • the aerosol generation device comprises a sensor including a capacitive unit having a plurality of capacitive cells, locking control circuitry and lock enable circuitry.
  • the method comprises: detecting a first gesture by the sensor, wherein upon the detection of the first gesture the locking control circuitry locks or unlocks the device if the locking control circuitry is enabled; and detecting a second gesture by the sensor, wherein upon the detection of the second gesture the lock enable circuitry enables or disables the locking control circuitry, wherein the sensor is configured to remain active for the detection of user gestures irrespective of the lock state of the aerosol generation device, and irrespective of whether the lock enable control circuitry is enabled or disabled.
  • the method can be used to lock or unlock the device when the locking control circuitry is enabled.
  • An advantage of the method is the convenience with which the security state of the device can be changed, allowing the settings to match the requirements of a particular situation.
  • the sensor is a capacitive sensor.
  • the first or second gesture may include a sequence of a touch and hold gesture followed by a swipe gesture.
  • the first or second gesture may include a sequence of multiple swipe actions.
  • the gestures may be input by a user.
  • the hold action and swipe action are natural gestures for a user, but the particular sequence of gestures is unlikely to be performed accidentally, adding security.
  • Another aspect of the invention provides a computer readable medium comprising instructions which when executed on a controller in an aerosol generation device as defined above, cause the controller to carry out steps according to the method defined above.
  • this two-level locking capability provides added flexibility to the user. Different lock states can easily and conveniently be switched between using the sequence of natural gestures.
