Definitions

  • the invention relates to a remote control device for controlling a number of electronic devices.
  • the present invention will mainly be described in conjunction with remote controlling multi-media devices, like e.g. TV sets.
  • Modern multi-media installations may comprise a plurality of electronic devices, like e.g. a TV set, a set-top box, a DVD player, a streaming unit, a cable or satellite receiver and the like.
  • electronic devices like e.g. a TV set, a set-top box, a DVD player, a streaming unit, a cable or satellite receiver and the like.
  • the present invention provides a remote control device with the features of claim 1 and a remote control method with the features of claim 12.
  • the present invention is based on the finding that common remote control devices for electronic devices are uncomfortable because one remote control is required for every device, a universal remote control has to be configured for every device or because they are easily lost.
  • the present invention therefore provides the remote control device that may be integrated into any type of flat surface, like e.g. a table surface or a side surface of a couch or shelf. This allows providing a table, e.g. in a living room, that at the same time may operate as a remote control device. It is understood, that the remote control device of the present invention may e.g. be provided only in a specific section of such a surface, i.e. the surface of the remote control device is smaller than the respective surface, e.g. the surface of the table.
  • the remote control device provides users with input elements.
  • the input elements of the present invention are dynamically formed on demand by the vertically movable input pixel elements.
  • the vertically movable input pixel elements may be seen as single pixels of the surface of the remote control device that may individually be elevated and retracted.
  • the control unit may therefore in a control mode recreate respective input patterns by controlling the respective input pixel elements.
  • the input pattern may e.g. comprise a binary pattern, where a "1" indicates an elevated input pixel element and a "0" indicates a retracted input pixel element.
  • the input patterns may therefore be seen as a kind of black-and-white image of the surface of a remote control device. Different input sections may therefore be created by elevating fields of input pixel elements. It is understood, that at least one input pattern may be provided in the control unit. However, more than one input pattern may also be provided, e.g. for selection by the user.
  • the control unit further monitors the recreated input pattern for any user interaction and controls an electronic device accordingly.
  • User interaction may refer to a user pressing down at least one of the elevated input pixel elements.
  • single ones of the elevated input pixel elements or groups of the elevated input pixel elements may be monitored for a downwards movement to detect the user input.
  • Every one of the elevated input pixel elements or groups of elevated input pixel elements may be assigned a respective control function. Therefore, the control unit may perform the respective control function to control the respective electronic device, e.g. by emitting a corresponding command to the electronic device.
  • control unit may retract all input pixel elements in a passive mode. In the passive mode, no control of any electronic device is performed by the remote control device.
  • the remote control device may be integrated into any surface, like e.g. a table surface and can therefore not get lost.
  • the input pixel elements may comprise magnetic actuators arranged under a ferromagnetic cap.
  • the control unit may be coupled to the magnetic actuators and may be configured to control the magnetic actuators to elevate the respective magnetic caps.
  • Electromagnetic actuators may e.g. be provided in the form of discrete wire coils or in the form of integrated coils that may e.g. be provided as traces on a printed circuit board.
  • Using electromagnetic actuators provides for a mechanically very simple arrangement that allows individually elevating single input pixel elements.
  • the ferromagnetic caps may e.g. be provided in a sliding mechanism, e.g. with respective guides. Driving an electric current through the magnetic actuators will then create a magnetic field that in turn applies a magnetic force to the ferromagnetic caps. The magnetic force then elevates the ferromagnetic caps.
  • the control unit may e.g. comprise a dedicated switching element for every one of the input pixel elements. It is further possible to control the elevation altitude of the single input pixel elements by modulating the driving current of the respective magnetic actuators, e.g. via a PWM modulation of the driving current.
  • the electromagnetic actuators may further be used to detect user input, e.g. a downward movement of the input pixel elements.
  • the control unit may e.g. measure or determine the inductance of the single electromagnetic actuators, e.g. by applying signals with specific frequencies or frequency patterns and analyzing the response of the electromagnetic actuator. A respective change of the inductance may then be used to detect the user input.
  • the input pixel elements may each comprise a pixel cap and a motor actuator coupled to the respective pixel cap.
  • the control unit may be coupled to the motor actuators and may be configured to control the motor actuators to elevate the respective pixel caps.
  • the motor actuators may e.g. comprise electric motors like e.g. miniature servo motors, linear motors or rotational motors. If rotational motors are used, a mechanical arrangement e.g. with levers and hinges may be used to translate a rotation into the lifting movement for the input pixel elements.
  • actuators for elevating the single input pixel elements may e.g. comprise ultrasonic actuators, pneumatic actuators and the like.
  • the remote control device may comprise actuation sensors arranged under the input pixel elements and configured to monitor the input pixel elements for actuation by a user and to provide respective actuation signals.
  • the control unit may be coupled to the actuation sensors and may be configured to detect the user input based on the actuation signals.
  • the actuation sensors may comprise single, dedicated actuation sensing elements or a spatially extended sensor device, like e.g. a sensor matt or the like.
  • the actuation sensors may comprise a sensing technology that is capable of detecting the user's hand or finger, i.e. the user's skin, though the input pixel elements.
  • the actuation sensors may be sensors that may detect movement of the input pixel elements. A downward movement of an elevated input pixel element may then e.g. be interpreted as a respective user input.
  • the actuation sensors may comprise hall-effect based sensors and/or capacitive sensors.
  • the actuation sensors may comprise a dedicated sensing element for every one of the input pixel elements.
  • Hall-effect and capacitive sensors are contactless sensors that may sense the user actuation through the input pixel elements.
  • control unit may be configured to select the input pattern based on a user selection of the electronic device to be controlled.
  • different electronic devices may be controlled with the remote control device. Further, the different electronic devices may require different input elements. For example a TV set may require a volume up/down input element, while a DVD player may require a forward/backward input element.
  • Every input pattern may e.g. define specific input fields.
  • the input fields may comprise groups of input pixel elements or single ones of the input pixel elements.
  • the input pattern may define for every input field a respective control function.
  • the control functions define which type of control, i.e. which function, is controlled in the respective electronic device.
  • Exemplary control functions may e.g. comprise an "increase volume”, a "decrease volume”, an "increase channel”, a “decrease channel”, a single number input function, or the like.
  • control unit If the control unit detects a user input on an input field that for example is provided for the "increase volume” function, the control unit will then emit the respective control command to the electronic device and the respective function will be performed in the electronic device.
  • the user selection may e.g. be performed via dedicated switches or buttons.
  • respective selection fields may be created with the input pixel elements.
  • different locations of the surface formed by the input pixel elements may be reserved for different electronic devices. If the user's hand is detected over one of the reserved locations, the respective input pattern may be generated by the control unit. It is understood, that the locations may be defined as areas on the surface.
  • the remote control device may comprise a control signal output device coupled to the control unit. Further, the control unit may be configured to control the electronic devices via the control signal output device.
  • the control signal output device serves to transmit control signals to the electronic devices.
