Description

[0001] The present invention relates to an educational system comprising a wall clock and a control device for the wall clock, the system having a clockwork with continuous time comprising date and time, the wall clock having a display device for visually displaying the time.

[0002] Routines often make everyday life easier. Especially for families with young children between the ages of 2 and 10, established routines can be made easier and even more enriching. However, in the stress of everyday life, even well-established routines are sometimes forgotten.

[0003] From around the age of 3-4, children also begin to develop an interest in the passage of time, such as the time of day and the seasons, and learn to tell the time. This interest often requires encouragement. However, everyday family stress can also lead to neglected child interest.

[0004] It is therefore an object of the present invention to provide an educational system with which both the adherence to routines in everyday life and the interest of children in time and clock reading can be promoted.

[0005] This object is achieved by a system comprising a wall clock and a control device for the wall clock, wherein the system has a clockwork, wherein the wall clock has a display device for visually displaying a time defined by the clockwork, wherein the system has a loudspeaker device for acoustically reproducing audio voice messages, wherein the control device comprises at least a first interaction device, wherein the first interaction device is designed such that at least a first interaction with a user and a second interaction with a user that differs from the first interaction can be detected by the interaction device, wherein the system is designed and configured such that the first detected interaction with a user causes the acoustic reproduction of a first audio voice message by the loudspeaker device,wherein the system is designed and configured such that the first audio voice message is an acoustic reproduction of a time visually displayed by the wall clock at the time of reproduction, wherein the system is designed and configured such that the second detected interaction with the user causes the acoustic reproduction of a second audio voice message by the loudspeaker device, wherein the system has a digital data memory and a computer processor, wherein the system is designed and configured such that digital voice information linked to digital time information can be stored by a user on the data memory, wherein the system is designed and configured such thatthat, at least within predefined time periods, the second audio voice message provides an acoustic reproduction of the stored voice information linked to digital time information. In particular, the wall clock can have a microcontroller that includes the computer processor and the digital data memory.

[0006] This enables the user to be informed about both the current time and an event through interactions with the control device, such as pressing a button or touching a touchscreen.

[0007] The clockwork can be mechanical, electromechanical, electronic, or fully digital, for example. In particular, the clockwork can display information about a continuous time, including the date and time.

[0008] The clockwork can, in particular, be a real-time clock (RTC). In this case, the time information can be stored as RTC values ​​in a data storage device designed as an RTC memory. The computer processor then links each RTC value stored in this way with an audio file, for example, with an assignment table to link the time information (here: RTC value) with the speech information (here: audio file).

[0009] For the purposes of the present invention, digital voice information is understood to mean information that can be reproduced acoustically and written in a language understandable to humans. The voice information can be stored in the data storage device, for example, in the form of an audio file, for example, in mp3, mp4, or wave format, or initially as a simple string variable or multiple character variables.

[0010] Digital time information is defined as a variable or data packet that can be stored on a computer and from which a date and time can be clearly read. For example, the system can be designed and configured such that the digital time information can be stored on the data storage as a Unix time, particularly with a signed 64-bit number. The use of a 64-bit system can enable particularly stable and long-lasting use of the system.

[0011] For the purposes of the present invention, an interaction is understood to be a goal-oriented action by a human. In the case of an interaction device comprising multiple actuating devices, such as mechanical buttons, the actuation of a first actuating device constitutes a first interaction, and the actuation of a second actuating device constitutes a distinct second interaction. An interaction therefore always consists of the human's action and the machine's goal of the action.

[0012] According to one embodiment of the system according to the invention, the wall clock has a single clockwork mechanism, so that the clockwork mechanism is connected to the display device in such a way that the display device visually displays the time defined by the clockwork mechanism. At the same time, the display device is connected to the data storage device and the computer processor in such a way that the processor reads the time defined by the clockwork mechanism and compares it with the time contained in the stored time information. This ensures, to the greatest extent possible, that the time information behind the audio voice messages is synchronized.

[0013] The individual clockwork can be designed, in particular, as a hardware real-time clock, for example, with a quartz oscillator. Alternatively, the individual clockwork can also be designed as a software real-time clock. The clockwork can be time-adjusted via a direct radio connection (radio clock) between the clockwork and a radio network or by occasionally connecting the computer processor to a user's radio-enabled device, such as a smartphone, via a data interface between the computer processor and the device.

[0014] According to an alternative embodiment of the system according to the invention, the wall clock has a first clockwork, wherein the first clockwork is connected to the display device in such a way that the display device visually displays the time defined by the clockwork, and wherein the wall clock has a second clockwork in addition to the first clockwork, wherein the second clockwork is connected to the data memory and the computer processor in such a way that the processor reads out the time defined by the second clockwork and compares it with the times contained in the stored time information.

[0015] If the second clockwork is not a radio-controlled clock, the second clockwork can be adjusted via a radio connection, for example, whenever a user connects to the wall clock's computer processor via a data interface such as a Bluetooth interface. The second clockwork can be designed, in particular, as a hardware real-time clock or a software real-time clock. This embodiment is particularly easy to integrate into existing clock designs and is therefore particularly cost-effective.

[0016] According to one embodiment of the system according to the invention, the wall clock and the control device are two spatially separable elements that are not physically connected to each other. This enables wireless remote control of the system, so that the wall clock can be mounted, for example, at an elevated location in a room, and the control device can be mounted in an easily accessible location, particularly for children.

[0017] According to one embodiment of the system according to the invention, the display device comprises an analog clock face with at least one tangible hour hand and one tangible minute hand, wherein the wall clock is designed and configured such that the hour hand and the minute hand visually indicate the time. It has been shown that such a design is particularly advantageous for children to learn to tell time.

[0018] According to one embodiment of the system according to the invention, the display device comprises a screen with a digital time display. In particular, the display device can comprise both an analog clock face as described above and, in addition, a screen with a digital time display. This allows the system to be used both to improve children's skills in learning to read analog clock faces and to improve their skills in understanding digital displays.

[0019] According to one embodiment of the system according to the invention, the system is designed and configured such that a plurality of digital voice information items, each linked to a respective digital time information item, can be stored by the user on the data memory, wherein the system is designed and configured such that with the second audio voice message an acoustic reproduction takes place at least once of that voice information whose linked time information defines a point in time which, with respect to the current time of the clockwork, lies no more than a time horizon of 60 minutes, preferably of 30 minutes and particularly preferably of 15 minutes, in the past and, with respect to all stored voice information and its linked time information, has the smallest time interval from the current time of the clockwork.

[0020] In particular, the second audio message can be designed in such a way that it acoustically reproduces both the speech information and the time information associated with the speech information. This makes it easier for the user to develop a sense of temporal perception.

[0021] According to one embodiment of the system according to the invention, the system is designed and configured such that the voice information linked to a time information item is automatically played back when the time, in particular the clock time, contained in the time information is reached. In this sense, the system also performs a reminder function.

[0022] According to one embodiment of the system according to the invention, the system is further designed and configured such that a user can store further digital voice information on the data storage device, which is not necessarily linked to time information. The second audio voice message provides acoustic playback of the further voice information, which is not necessarily linked to time information, if the second interaction with a user occurs outside the time horizon. In particular, this allows multiple positive voice messages to be stored, for example, statements such as "It's great that you're here." One voice message is selected randomly and played over the loudspeakers if the second interaction with a user occurs outside the time horizon described above.Furthermore, the system can be designed and configured such that, in the case of two interactions occurring close together in time, according to the second interaction within the time horizon, for example if a second interaction occurs twice within 10 seconds, preferably 5 seconds, in the latter second interaction, speech information that is not necessarily linked to time information, in particular positively charged speech information, is reproduced as an audio voice message.

[0023] According to one embodiment of the system according to the invention, the system comprises a light source, in particular an LED light, wherein the light source emits light with a first brightness as long as the time of the clockwork is within the time horizon, wherein the light source emits light with a second brightness that is lower than the first brightness, or no light at all, as long as the time of the clockwork is outside the time horizon. This also makes it visually apparent to the user within the time horizon that a time has been reached that is linked to voice information. This voice information can be queried through the second interaction, since the system reproduces the voice information as an audio voice message.

[0024] According to an alternative embodiment of the system according to the invention, the system is designed and configured such that a plurality of digital voice information items, each linked to a respective digital time information item, can be stored by the user on the data storage device, wherein the system is designed and configured such that the second audio voice message acoustically reproduces that voice information whose linked time information defines a point in time that lies in the future with respect to the current time of the clockwork and has the shortest time interval from the current time of the clockwork with respect to all stored voice information items and their linked time information items. The voice information items can in particular be stored as recurring voice information items, for example, repeated daily or weekly.This allows routines to be stored in the form of repetitive voice information. The second interaction then allows the user to be acoustically informed by the system about the next upcoming routine.

[0025] In particular, the second audio message can also be designed in such a way that it acoustically reproduces both the speech information and the time information associated with the speech information. This makes it easier for the user to develop a sense of temporal perception.

[0026] Additionally or alternatively, the system can also be designed and configured such that the second audio message acoustically reproduces the voice information and the time span between the current time of the clockwork and the time associated with the event. This can facilitate the estimation of the time still available for other tasks and promote the ability to learn to calculate time differences.

[0027] According to a further embodiment of the system according to the invention, the interaction device comprises a first tangible, physical mechanical actuating device, such as a first button, a first lever, a first rotary control, a first slide control, or a first switch, so that actuating the first mechanical actuating device represents the first interaction with a user. This enables particularly simple and thus child-friendly operation of the control device. In particular, the physicality of the actuating device can address the sense of touch of adolescents, which in turn can be very beneficial for sensory development.

[0028] According to one embodiment of the system according to the invention, the interaction device comprises, in addition to the first mechanical actuating device, a second tangible-physical mechanical actuating device such as a second button, a second lever, a second rotary control, a second slide control or a second switch, so that actuation of the second mechanical actuating device is the second interaction with a user.

[0029] In particular, the interaction device may consist of the first actuating device and the second actuating device.

[0030] For example, the first actuating device can be a first button and the second actuating device a second button. In this case, the interaction device preferably only has these two buttons. Particularly preferably, the entire control device then only has these two buttons. This enables particularly easy operation, since no other confusing elements are provided on the control device.

[0031] According to one embodiment of the system according to the invention, the wall clock includes the loudspeaker device. This enables particularly good acoustics in the room, since the wall clock can often be mounted in an acoustically optimal position in the room.

[0032] In particular, the loudspeaker device can have loudspeaker outputs arranged on a rear and / or side surfaces of the wall clock. This enables a particularly simple and cost-effective manufacturing process.

[0033] Additionally or alternatively, the speaker outputs can also be integrated into the front of the wall clock, particularly the clock face. This, in turn, ensures particularly rich acoustics.

[0034] According to an alternative embodiment of the system according to the invention, the control device comprises the loudspeaker device. This enables a particularly energy-efficient design of the system.

[0035] Furthermore, according to a further embodiment, the system can also comprise, in addition to the loudspeaker device, a further loudspeaker device that is designed, configured, and integrated into the system in such a way that the further loudspeaker device can be spatially separated from the actual loudspeaker device at least up to a maximum distance—for example, within a Bluetooth radius—and audio voice messages played by the actual loudspeaker device are also played by the further loudspeaker device essentially simultaneously. This enables the stationing of a "satellite" in a different room than the room in which the wall clock hangs.

[0036] According to one embodiment of the system according to the invention, the wall clock has an integrated wall mount, and the control device has an integrated wall mount. This allows the user to attach it to an interior or exterior wall particularly easily.

[0037] According to one embodiment of the system according to the invention, the control device has a first wireless data communication interface, in particular a first infrared interface, wherein the loudspeaker device has a second wireless data communication interface, in particular a second infrared interface, wherein the control device and the loudspeaker device are designed and configured such that at least the first interaction with the interaction device and the second interaction with the interaction device effect wireless data communication between the first data communication interface and the second data communication interface.This makes it possible for an interaction with the control device, such as pressing a button in the sense of the first actuating device, to cause the transmission of a communication signal, for example the transmission of an infrared signal, from the control device to the wall clock, which in turn causes the acoustic reproduction of the first audio voice message.

[0038] According to one embodiment of the system according to the invention, the wall clock comprises the data storage device, wherein the wall clock comprises a third communication interface, in particular a Bluetooth interface and / or WLAN interface and / or USB interface, wherein the system is designed such that the digital voice information can be stored on the data storage device via the third communication interface. This enables - apart from the initialization of the voice information - autonomous operation of the wall clock and control device in terms of data communication technology. This is because retrieving the voice information does not require a permanent data connection, for example to a WLAN network or the Internet. This keeps the intensity and radiation duration of the electromagnetic radiation emitted by the wall clock and the control device as low as possible.

[0039] According to one embodiment of the system according to the invention, the system, preferably the wall clock or the control device, comprises an activation device, wherein the activation device is designed such that a user can selectively put the third data communication interface into an operating state and into a standby state by interacting with the activation device, wherein the third data communication interface emits essentially no electromagnetic radiation in the standby state, wherein the activation device is preferably a third tangible-physical mechanical actuating device such as a third button, a third switch or third lever, so that actuating the third actuating device is the interaction with the activation device.This allows the user to ensure that during normal operation - when no initialisation of the voice information takes place - the intensity and duration of the electromagnetic radiation emitted by the wall clock and the control device is kept as low as possible.

[0040] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged relative to each other in an installed state such that the spatial distance between the wall clock and the control device is at least 30 cm. An installed state is understood to mean a state in which both the wall clock and the control device are firmly attached to a wall, for example, by means of a wall mount.

[0041] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged in an installed state such that the spatial distance between the wall clock and the control device is at least 50 cm.

[0042] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged in an installed state such that the spatial distance between the wall clock and the control device is at least 100 cm.

[0043] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged in an installed state such that the spatial distance between the wall clock and the control device is a maximum of 250 cm.

[0044] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged in an installed state such that the spatial distance between the wall clock and the control device is a maximum of 200 cm.

[0045] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged in an installed state such that the spatial distance between the wall clock and the control device is a maximum of 180 cm.

[0046] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged in an installed state such that the spatial distance between the wall clock and the control device is at least 30 cm and a maximum of 250 cm.

[0047] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged in an installed state such that the spatial distance between the wall clock and the control device is at least 50 and a maximum of 200 cm.

[0048] According to one embodiment of the system according to the invention, the wall clock and the control device are arranged in an installed state such that the spatial distance between the wall clock and the control device is at least 100 cm and a maximum of 180 cm.

[0049] It has been found that for the above-mentioned minimum values, maximum values ​​and parameter ranges, particularly advantageous communication solutions between the wall clock and the control device result, which are particularly low in radiation.

[0050] According to one embodiment of the system according to the invention, the front of the wall clock extends over an area of ​​at least 15 cm and a maximum of 50 cm, preferably at least 20 cm and a maximum of 40 cm. This ensures good visibility of the clock face, especially for children.

[0051] According to one embodiment of the system according to the invention, the front of the control device extends over an area of ​​at least 50cm 2 and a maximum of 200cm 2 This simplifies wall mounting and provides a tactile, user-friendly experience, especially for children.

[0052] According to one embodiment of the system according to the invention, the system comprises a computer-implemented control algorithm, wherein the third data communication interface and the control algorithm are configured such that a user can store voice information and associated time information on the data storage device via Bluetooth or WLAN using the control algorithm implemented on a Bluetooth- or WLAN-enabled terminal. This enables app-supported initialization of the voice information. The system can also be configured in particular such that the control algorithm causes an acoustic signal to be output via the loudspeakers of a terminal on which the control algorithm is installed and / or causes this terminal to vibrate when a point in time is reached that is contained in time information linked to stored voice information.

[0053] According to one embodiment of the system according to the invention, the system comprises an electrical energy storage device, preferably a lithium iron phosphate accumulator, wherein the energy storage device is designed and arranged such that it supplies the loudspeaker device with electrical current. In particular, the energy storage device is integrated into the wall clock if the wall clock has the loudspeaker device, or integrated into the control device if the control device has the loudspeaker device.

[0054] The wall clock or the control device can then in particular have a charging interface, in particular a USB or mini-USB interface, via which the energy storage device can be connected to a power grid and charged.

[0055] According to one embodiment of the system according to the invention, the energy storage device has a capacity of 10Wh to 50Wh.

[0056] According to one embodiment of the system according to the invention, the wall clock comprises a plastic housing on the back, preferably an injection-molded plastic housing. In particular, the wall clock can comprise only a single plastic housing on the back. This facilitates the production of the wall clock.

[0057] All previously described embodiments can be combined within the meaning of the present invention, as long as a combination is logically possible.

[0058] Further features, advantages, and possible applications of the present invention will become clear from the following description of a preferred embodiment and the accompanying figures. They show: Fig. 1: a schematic representation of the electronics of an embodiment of the system according to the invention, Fig. 2: a frontal view of the Fig. 1 shown embodiment.

[0059] In the Fig. The system 1 shown in Figure 1 comprises a wall clock 2 and a box-shaped control device 3. The wall clock has an electronic clockwork 4, which is powered by a battery 24. The clockwork 4 is designed as a radio-controlled clock and includes a quartz clock. The radio-controlled clock receives a time signal transmitted by radio from a time signal transmitter and uses this time signal to adjust the quartz clock. The clockwork shown here is an electronic hardware real-time clock and can provide not only the current time but also the current date as an output signal.

[0060] With an integrated wall mount 13, the wall clock can be attached to a wall. As shown in Fig. 2, the clockwork also mechanically drives an hour hand 20 and a minute hand 21, so that a user and especially children can read the current time from the clock face 19 of the wall clock 2 or can learn to read it, especially when the wall clock 2 is attached to a wall.

[0061] In addition, the wall clock has a back - as in Fig. 1, a microcontroller 14' with a computer processor, which is powered by a lithium iron phosphate accumulator 10. The microcontroller 14' comprises a digital data storage device 14, on which audio files can be stored, and a Bluetooth interface that can be selectively activated and deactivated via a mechanical switch 16. When the Bluetooth interface is activated, a user can load voice information in the form of audio files, along with associated time information in the form of a digital time stamp, for example, a Unix time, or as an RTC file, onto the digital data storage device using a Bluetooth-enabled terminal device such as a smartphone and a control algorithm installed thereon—an app.

[0062] The microcontroller shown here also contains an additional clock mechanism, also in the form of a hardware real-time clock, which is time-adjusted via the Bluetooth interface as soon as a wireless connection is established via a smartphone connected to the Bluetooth interface. This ensures sufficient time synchronization between the two clock mechanisms.

[0063] The wall clock therefore stores both the time currently displayed by the wall clock and the corresponding date, as well as the voice information linked to the time information - date and time. For example, a user can use a smartphone to continuously store the event called "Eat a healthy snack" as voice information on the data storage device 14 for each weekday at 4 p.m. In such a routine, the voice information, which essentially consists of an audio file with which, among other things, the statement "A healthy snack is eaten" can be acoustically reproduced via the loudspeaker device 5, can also be linked to multiple pieces of time information. In this way, a routine fixed for weekdays can be stored as voice information on the data storage device 14 - here in the form of an audio file linked to digital time stamps (e.g. RTC file).As soon as the user has completed the initialization of this routine on the wall clock 2, he or she can deactivate the Bluetooth interface again via the mechanical switch 16, so that the wall clock 2 operates in a state with the Bluetooth interface deactivated - particularly low-radiation.

[0064] The loudspeaker device 5 is in the Fig. 1 and Fig. 2 shown system 1 is integrated into the wall clock 2 on the back as shown in Fig. 1. The loudspeaker device 5 is connected to the microcontroller 14', so that it can also be powered by the accumulator 10 and acoustically reproduce the audio files stored on the data storage device 14.

[0065] In the system shown here, the wall clock 2 also has an on / off switch 17, with which the microcontroller 14' and thus also the loudspeaker device 5 can be put into a power-saving standby state (off), in which they no longer perform any functions. This can save power, for example, during storage.

[0066] A charging interface 11 is also integrated into the frame of the wall clock 2, which is connected to the accumulator 10 via the microcontroller 14'. The accumulator 10 can be charged by connecting this charging interface 11 to the household power supply.

[0067] The educational function of the system is achieved through the interaction of the wall clock 2, described in detail so far, with the control device 3. The control device 3 is advantageously also mounted on the wall - at a height accessible to children aged 2 to 10 years and substantially below the wall clock 2. In the system shown here, the control device 3 has an interaction device 18 with precisely two actuating devices 6 and 7 in the form of two buttons. By pressing the first actuating device 6, a first infrared signal can be generated, which is sent via the first infrared interface 8 to the infrared interface 9 of the wall clock. For the transmission of infrared signals, the Fig. 1 and Fig.The vertical alignment of wall clock 2 and control device 3 shown in Figure 2 is advantageous but not absolutely necessary. This first signal received by the wall clock causes the first audio message to be played back via loudspeakers 5, with which the time currently displayed by wall clock 2 is acoustically reproduced. Thus, children in particular can acoustically learn—by pressing button 6—what time can be read from the analog clock face 19 in conjunction with the hour hand 20 and minute hand 21.

[0068] If a time is reached that is linked to voice information in the form of time information, the voice information is automatically played back acoustically via the loudspeakers in the form of the corresponding audio voice message.

[0069] Within a predefined time horizon after reaching the time linked to the time information, pressing the second actuating device 7, the second button, can cause the second audio voice message to be played back via the loudspeakers 5, namely the audio voice message contained in the audio file of the voice information whose time stamp contains the time that, of all the stored voice information, is closest in time - looking back in time - to the current time of the clockwork.If a child presses button 7 on a weekday at around 4:10 p.m. - in the example described above - and no further voice information is stored between 4 p.m. and 4:00 p.m., the wall clock would play the audio voice message "a healthy snack is being eaten" via the loudspeaker device 5, together with the corresponding time information "at 4 p.m.", i.e. together "a healthy snack is being eaten at 4 p.m." or "a healthy snack is being eaten now.". This tells the child which routine is currently in progress and at what time this routine should be performed.

[0070] During the time horizon, i.e. in the example from 4:00 p.m. to 4:15 p.m., LED 15 also lights up to indicate that a routine is currently pending and the user can find out about the routine by pressing the second button.

[0071] Outside of a time horizon, the second audio voice message, which is output by the loudspeaker device when the second button is pressed, is, in the embodiment shown here, a general and untime-related statement such as "Today is a great day to start an adventure. Go for it!" Outside of a time horizon, LED 15 also does not light up.

[0072] A button battery 12 can be used to power the control device. This has proven sufficient.
