FIGS. 3a and 3b are cross-section views showing operation of the control mechanism according to embodiments of the present invention;
FIGS. 3a and 3b show in more detail the control device 36 according to some embodiments, when positioned on a control screen 30, 34.
The screen 30, 34 comprises a display 64 which can be used to display a graphical user interface for controlling the system 10 as will be described below. None of the display circuitry is illustrated for clarity. A plurality of elements are arranged beneath the display 64, and these cooperate with the one or more magnetic elements 60 in the device 36 to determine the angle of rotation and tilt of the device 36, and to secure the device 36 to the screen 30, 34. For example, a magnetic element 66 is disposed beneath the device 36, with its polarity arranged so as to attract the one or more magnetic elements 60 in the device 36. In this way the device is secured to the screen 30, 34 (recalling that the screen 30, 34 may be placed at an angle as shown in FIGS. 1 and 2). Further, a plurality of magnetic sensors 68 are provided in order to detect the magnetic field generated by the one or more magnetic elements 60 and so determine the orientation of the device 36. This aspect is covered more fully in FIGS. 3b and 4. In an alternative or additional embodiment, resistive or capacitive touch or proximity sensors may be disposed in the vicinity of the device, which can be used to determine the tilt and/or position of the device.
The magnetic field generated by the first magnet 60 a is asymmetric in the plane of the sensors 68, and thus data from the sensors can be used to determine the angle of rotation of the device, i.e. the angle of rotation about the axis II. Further, as can be seen with respect to FIG. 3a , tilting the device 36 moves the ends of the first magnet 60 a nearer and further from corresponding sensors of a sensor pair 68 a. This tilt can therefore be detected by comparing the magnetic field sensed by corresponding sensors of the sensor pair 68 a.
As use of the device 36 can grant access to certain parts of the system 10, depending on the identity of the user, in some embodiments a mechanism is provided to ensure the device 36 remains attached to or within a certain distance of the user. For example, in one embodiment (see FIG. 6) the device 36 comprises two parts 36 a, 36 b. The first part 36 a corresponds to the device as described in the embodiments of FIGS. 3a and 3b . The second part 36 b comprises a cord 80 and a transceiver 82, and is detachably connected to the first part 36 a. The cord 80 allows the device 36 to be worn around the user's neck or wrist so that the second part 36 b at least remains attached to the user at all times. Those skilled in the art will appreciate that alternative means may be provided to attach the second part 36 b to the user. In use, the first part 36 a can be detached from the second part 36 b, to allow the first part 36 a to be placed on the control screens 30, 34 and used to control the system 10 in the manner described above. To ensure the first part 36 a remains within the control of the user, the transceiver 82 may periodically transmit a polling signal to the first part 36 a, and particularly the beacon 58. In response to the polling signal, the beacon 58 may transmit an answer signal which is received by the transceiver 82, thus ensuring that the first part 36 a is not too distant from the second part 36 b (and implicitly the user). If the answer signal is not received, or the signal is received with a signal strength which is below a threshold, the second part 36 b may deem that the first part 36 a is too distant from the user, and issue an alarm. For example, the second part 36 b may vibrate, sound an alarm noise, or provide visual feedback.
