Description

Technical area

The present invention relates to a wristwatch, in particular an electronic wristwatch having a high-resolution display screen.

State of the art

Wristwatches can be classified into two main families depending on the type of movement used. Electronic watches, most often regulated by a quartz, have the advantage of high precision and moderate cost thanks to industrial manufacturing techniques. The time calculated by electronic watches is most often displayed digitally on a liquid crystal segment display, or sometimes by means of hands driven by a step-by-step motor whose operation is regulated by the quartz. Liquid crystal segment displays have the disadvantage of limited contrast making reading the digital symbols formed by the segments uncomfortable, especially in low ambient light. Stepper motors generally cause the needles to move jerkily, judged not to be very quiet and not very representative of the continuous flow of time.

The mechanical movements allow the time to be displayed by means of hands or other indicators moving almost continuously while allowing a comfortable reading even in low ambient light. Furthermore, the extraordinary ingenuity of certain mechanical movements and the possibility of visualizing their components is considered fascinating by many users, especially in the case of skeleton watches allowing parts of the movement to be admired, through the crystal and the dial. Mechanical watches therefore arouse considerable enthusiasm and there is an established commercial need for mechanical watches with a dial driven by moving movement elements.

The manufacture of mechanical movements, however, is complex so that mechanical watches are generally more expensive than electronic movements. This is particularly the case with mechanical movements with major complications or when the movement must be decorated or machined to be permanently visible behind the glass. Mechanical watches displaying their complications are therefore almost exclusively reserved for the upper segment of the luxury watch market. In addition, only a small portion of the potentially interested clientele can have access to the collection of mechanical watches that are necessary to appreciate the multitude of different complications offered by watchmakers.

Moreover, the precision of mechanical movements is generally less good than that of electronic movements of comparable price. This results in a certain disappointment from part of the clientele who expects high precision from a luxury watch.

GB2425370 describes a table clock comprising a video screen for displaying a looped film with representations of humans. This solution is not suitable for a wristwatch. US20050278757 describes a system for downloading watch faces displayed on a device. US20030214885 describes a watch whose dial is replaced by a screen allowing the time to be represented in different ways. None of these solutions of the prior art makes it possible to display the movement of the watch. These solutions do not offer the fascination of beautiful mechanical watches, and are intended for lovers of electronic watches. WO2011000893 , which comes under Art 54 (3) EPC, discloses a wristwatch comprising a microcontroller arranged to reproduce on an electronic display the simulation of a mechanical watch movement.

There is therefore a long-established need for a watch which makes it possible to resolve these problems of the prior art and to meet the sometimes contradictory expectations of the market.

In particular, there is a need for a watch allowing its user to admire the operation of the mechanical movement, while offering precision and a price comparable to those of a quartz watch.

There is also a need for a more economical complication watch than ordinary mechanical watches.

There is also a need for a watch that makes it possible to easily replace the movement viewed, in order to admire, for example, different types of mechanical complications.

There is also a need for a wristwatch making it possible to display a large number of different indications without however cluttering the display.

There is also a need for a wristwatch making it possible to personalize the type of information displayed, and the manner of presenting this information.

Brief summary of the invention

An object of the present invention is to provide a wristwatch combining the advantages of watches with mechanical movements and those of electronic watches.

According to the invention, these aims and these needs are achieved in particular by means of a wristwatch as defined in independent claim 1. Preferred embodiments are defined in dependent claims 2 to 12.

In addition, independent claim 13 defines a corresponding method of displaying information in an electronic watch. The dependent claims 14 and 15 define particular embodiments of this process.

This watch thus makes it possible to display a simulated mechanical movement as complex as desired while avoiding the costs of manufacturing a real, physical and tangible mechanical movement. In addition, the precision of this watch can be as high as that of an electronic watch while offering the animations of a higher category mechanical watch.

The invention starts in particular from the observation that modern electronic displays allow sufficient realism to display a credible simulation of a complex mechanical movement; the necessary resolution would have been impossible to obtain a few years ago, or would have required power consumption incompatible with integration into a wristwatch.

The invention also starts from the observation that the computing power of current watchmaking microcontrollers (that is to say microcontrollers of size and consumption compatible with a watchmaking application) makes it possible to calculate and display in real time a realistic simulation. of a complex mechanical movement.

The simulated mechanical movement is advantageously displayed over the entire surface of the electronic display, which is mounted edge to edge against the internal face of the flange or the bezel. In this way, the simulated mechanical movement occupies the position and dimensions of an actual mechanical movement. Indicating members, for example needles, discs, cylinders etc. can be displayed on the display. Control means make it possible to modify the display and to select a mechanical movement from among several available movements. It is also possible to display a simulated dial, or a real dial, totally or partially covering the simulated mechanical movement.

In a preferred embodiment, the display is a display associated with a touch sensor, for example a display associated with a multi-touch or single-touch touch sensor. This increases the realism of the representation; the user can for example influence the position or displacement of a component of the movement by pressing or moving the representation of this component. For example, it is possible to perform a simulated virtual movement in which the user can turn or stop the hands, or certain gears, or other elements, by pressing on their representation or by moving this representation with a trajectory of the finger on the screen.

In one embodiment, the watch comprises a crown outside the case and a representation of the virtual and simulated crown stem displayed on the screen opposite this crown. The position of the crown stem is modified by the microcontroller of the watch when this microcontroller detects an actuation of the crown, so as to simulate a direct action of the crown on the simulated crown stem. This crown can also be used for setting the time or for winding the simulated mechanical movement; this movement can for example stop after some time if it is not wound up by the physical crown.

Similarly, the action of the physical push buttons on the movement can be simulated by displaying a simulated organ next to the push button, the position of which is modified when the push button is actuated, so as to simulate a direct action. on said member simulated by said push-button.

In a preferred embodiment, the wristwatch further comprises an accelerometer used for example to increase the realism of the representation, by making it dependent on the accelerations undergone by the watch. For example, the position of at least one element of the movement depends on an output signal from the accelerometer. It is so possible to simulate the displacement of an oscillating weight for winding the simulated movement according to the watch, to visualize the deformations of the hairspring or the displacements of a tourbillon or of the balance according to gravity, or to show the oscillations of the train gear or other components when the watch is shaken.

In order to make the effect of these accelerations realistic, at least some elements of the movement have a virtual mass used for the simulation. The microcontroller therefore calculates the forces and the displacement undergone by these elements as a function of the measured acceleration, for example gravity or a shock, and displays these displacements or deformations. At least some elements, for example the springs or the hairspring also have virtual rigidity and deform as a function of the measured accelerations or the displacements of other components of the simulated movement. The acceleration can for example be measured along 3 axes. It is also possible to measure rotations along one or more axes with a gyroscope.

In one embodiment, the rate of movement depends on the measured accelerations. For example, it is possible to take into account the effect of gravity and of shocks on the regulating member in order to affect the rate of this regulating member or the position of a tourbillon. A simulated barrel can discharge if the accelerometer does not detect any acceleration to move the oscillating mass, and mechanical motion can slow down and then stop if discharged.

The time displayed by the displayed movement therefore preferably depends on the results of the simulation, taking into account the rigidity of the parts or the measured accelerations. According to the invention, the time of the simulated movement is synchronized with the time determined by the quartz movement, in order to reset the simulated mechanical movement. This synchronization can be performed automatically, for example periodically or in the event of a variation. exceeding a predetermined threshold, and / or at the request of the user by an appropriate command.

One advantage of the present solution is that it makes it possible to simulate and display mechanical movements which would be impossible or very expensive to manufacture in practice. For example, it is possible to display virtual mechanical movements, simulated with a regulating organ oscillating at a much higher frequency than in a classical movement, and with organs which rotate much faster, producing a more interesting animation. For example, according to the invention, oscillating masses or balances are simulated with a very high density, and other moving parts with a density that is on the contrary lower than that permitted by ordinary materials. Furthermore, it is possible to simulate parts with very low, or even zero, coefficients of friction and with very high, or even infinite, stiffness and solidity. Finally, barrel or hairspring springs can be simulated with much greater return stresses than in the prior art. In an advantageous embodiment, the simulation is however always a “realistic” simulation, calculated taking into account correct physical laws even if it is based on properties of non-existent materials.

In an advantageous embodiment, the display does not reproduce a simple animated image or a video previously recorded and displayed in a loop, but a calculated simulation of the position of the elements displayed taking into account for example the shape and the simulated mass. of these elements and of the environment (for example buttons, acceleration, etc.). Each successive image is therefore calculated in real time by the microcontroller and generated dynamically taking into account external parameters. This increases the realism.

The display is preferably a display associated with a two-dimensional touch sensor making it possible to detect the movements of at least one finger in at least two different directions, the watch comprising a processing circuit specifically designed to interpret signals from the touch sensor, to select a screen from among several screens available as a function of these signals, and to display this screen over the whole of said display. The processing circuit is specifically designed so as to cause scrolling of screens in order to permanently replace the map initially displayed by another screen, the direction and the direction of scrolling depending on the direction and direction of said displacement. Each screen displayed can be associated with an application determining the animated image displayed.

The wristwatch also has the advantage of switching from one screen to another very simply, by simple horizontal or vertical movements of the finger on the crystal, taking into account the direction and direction of movement of the finger on the screen.

Scrolling from one screen to another can for example correspond to a change of watch mode. For example, the replacement of a simulated mechanical display is done by scrolling through screens, and by replacing the entire image displayed on the watch with the image of another screen.

Example (s) of embodiment of the invention

The figure 1 schematically illustrates various components of a simulated mechanical watch 1 according to the invention. In this example, it comprises a housing 5 housing a microcontroller 10 displaying indications on a high-resolution digital display 4 which occupies almost the entire surface under the glass, and thus serves both as a watch face and as a time indicator. . In a preferred embodiment, the display consists of a color liquid crystal matrix display (LCD or TFT) with at least 150 × 150 pixels. Other types of displays, including displays based on OLED technology for example, can be employed. Furthermore, the watch could also include several displays, for example several digital displays, or a digital matrix display combined with hands or other mechanical indicators.

The microcontroller makes it possible to execute different applications in order on the one hand to determine the current time and other chronological indications as a function of the output signals of a quartz oscillator 11 in the housing, or of another reference signal. temporal. On the other hand, the microcontroller runs computer applications stored in a semi-permanent memory in order to control the indications displayed on the display 4 according to the time indications and the commands of the user or of various sensors. The applications executed by the microcontroller can be updated for example through a wireless interface not shown, or a micro-USB type connector for example, in order to load other portions of codes making it possible to display other indications or the same indications in a different way.

The watch can also include several microcontrollers, for example a microcontroller to control the matrix display, another microcontroller to control the touch interface, and a general microcontroller to determine the indications to be displayed at each moment, according to the selected card. These different microcontrollers can also be grouped together differently.

The display 4 is preferably a display associated with a touch sensor, for example a display associated with a single touch or multitouch touch sensor. By multi-touch sensor is meant in the present application a touch sensor capable of detecting several simultaneous contact points, for example the simultaneous movements of several fingers on the touch surface. It is surprising to use a multitouch screen on the small surface of a wristwatch, despite all expectations this technology is however effective in entering complex commands more quickly than with a single touch screen. The electrodes of this equipment are preferably associated with a circuit or with software which interprets these simultaneous contacts and which converts them into commands executed by the microcontroller 10.

Regardless of the single-touch or multi-touch aspect, the watch is characterized by displaying a single icon or card at a time, with each card filling the entire screen. The different cards are arranged on a single plane and the choice of a screen is made only by horizontal or vertical movements, in the same plane, without ever switch to a different plan. The risk of losing the user in navigating between several planes of icons or superimposed maps is thus avoided.

The course of the programs executed by the microcontroller 10 can also be modified by acting on monostable pushbuttons 41 and / or on the axial and / or angular position of a crown 42 (optional). Reference numeral 43 denotes additional light indicators, for example light diodes on the outer surface of the case 5 or the bracelet. The user interface can also include a loudspeaker (not shown) to reproduce sounds generated or stored by the microcontroller, a wireless interface (not shown) of the ZigBee or Bluetooth type for example, a microphone, etc.

The watch can also include a speaker which can be used to reproduce sounds. In one embodiment, the sounds generated and reproduced depend on the simulation displayed, for example in order to reproduce a “tick tock” synchronized with the oscillations of the simulated regulating organ.

The power supply of the watch is advantageously done by means of a rechargeable battery through a micro- or nano-USB connector, a specific or proprietary connector or, in a variant, through a radiofrequency interface. .

The wristwatch of the invention also advantageously comprises an accelerometer 12 capable of measuring the acceleration undergone by the watch and of supplying a signal to the microcontroller 10 depending on this acceleration. The accelerometer is preferably a 3D accelerometer capable of measuring acceleration in three dimensions, and of determining the vertical direction during periods of immobility. This acceleration is for example useful for controlling and rotating the display according to the orientation of the watch, and for simulating the effect of the acceleration on the parts shown on the screen, in particular the deformation of the hairspring, as in will see it below. It is also possible to use an accelerometer combined with a gyroscope to measure angular acceleration along one or more axes, and to simulate the effect of rotations on the displayed representation.

The figures 2 to 5 illustrate various display examples on a wristwatch 1 according to the invention. The illustrated watch comprises in particular a bracelet 2 and a case 5 provided with a crystal 3 covering a digital matrix display 4. It integrates for example the circuit of the figure 1 .

The box 5 may include control members, for example push-buttons 41, a crown 42, etc., which are however not essential for handling; on the figures 2 , 3 and 5 , the watch has no crown and only has pushbuttons 41 for switching the screen on or off, for adjusting its brightness or for controlling applications. It is also possible, in an option, to produce a watch without a push-button and / or in which the screen is turned on or off via the touch screen, for example by long pressing on a predetermined area of the touch screen. . As an option, a light sensor (not shown) automatically adapts the intensity of the screen to the ambient light. This sensor can also be used to adapt the intensity and direction of shadows simulated and drawn on the display according to the intensity and direction of the ambient light.

The crystal 3 closes the upper surface of the case and covers the digital matrix display 4. It is preferably made of sapphire or another scratch-resistant material, and covered with an antireflection treatment. In a preferred embodiment, the crystal is convex cylindrical, or possibly convex spherical.

Transparent electrodes, not shown, are placed in or under the glass 3 in order to detect the presence of a finger or a stylus. The detection technology preferably uses methods known in the state of the art, for example capacitive detection.

The microcontroller 10 makes it possible to interpret the signals coming from the electrodes and to display on the matrix display 4 indications which depend on these signals.

The user can switch from one display mode to another, and for example replace the display of the figure 2 by that of one of the figures 3, 4 or 5 , or by another display, simply by scrolling through the displays on the screen by moving your finger on the screen in the desired scrolling direction.

The figure 2 illustrates a display mode in which the time is displayed by means of a simulated virtual mechanical movement and displayed on screen 4. In this example, the hours, respectively the minutes, are displayed by means of simulated jumping cylinders 15 , 16 indexed almost instantaneously at each change of hour or minute. The seconds are displayed by means of a simulated linear retrograde seconds hand 17 moving at 6 o'clock at the bottom of the screen. The movement illustrated here is of the skeleton type and reveals part of the cogs and other components of the movement. In this example, most of the wheels and pinions are arranged around horizontal axes (parallel to the dial).

The wristwatch therefore displays the simulated movement and the indicators 15, 16, 17 over the entire surface of the electronic display, so that it occupies the position and dimensions of an actual mechanical movement in a skeleton watch. for example. The user thus has the impression of wearing a real mechanical watch. In order to enhance the realism and the impression of three-dimensional depth, the microcontroller 10 can display shadows on the organs of the simulated movement; the intensity and direction of shadows may also depend on ambient light measurements taken by one or more light sensors.

The user can replace a displayed simulated movement with another available movement. The figure 3 illustrates the display of a movement allowing the display of the date, respectively of the day of the week by means of jumping rollers 18 and of a retrograde linear hand 19 respectively. These elements can be represented on the same display 4 instead of the indications on the figure 2 , the user being able to switch freely from one representation to another and replace the display of the first movement with that of the second movement.

The figure 4 illustrates another way of displaying the time by means of hands 20 of the hours and minutes displayed on the screen 4. In this representation, the hands 20 rotate in front of a simulated skeleton movement comprising in particular cogs 30 and other elements not shown, for example a regulating organ, a barrel, an oscillating weight, or other simulated complications.

The physical crown 42 on the outside of the watch can be manipulated to wind or time this simulated movement. In an advantageous embodiment, a simulated crown rod 420 is displayed on the screen 4 opposite the crown 42; this rod is controlled by the microprocessor so as to follow the manipulations of the physical crown 42, giving the user the impression of actually manipulating this crown rod 420 and the organs which are linked to it.

Likewise, the action on the push-buttons 41 outside the housing 5 advantageously has repercussions on the corresponding members 410 displayed on the screen 4, giving the user the impression of manipulating these members.

The user can also interact with the elements of the simulated movement through the touchscreen 40. For example, in one embodiment, he can move or block the hands 20, or other components, simply by moving or pressing the button. finger on the displayed representation of these components. Advantageously, this displacement causes a modification of the rate of the movement. For example, if the user moves a hand with the finger, the displayed time is permanently modified, and the hand starts again from the location where the user left it. Likewise, if a user prevents a wheel or pinion from turning, the simulated movement is stopped for the duration of the lockup, and the watch is thus delayed. In one embodiment, the user can also temporarily remove components from the movement, for example cogs, bridges etc., by means of the finger; this allows for example to observe parts in the background that would be hidden by others.

In one embodiment, the watch comprises an accelerometer 12 generating an output signal which influences the rate of the simulated movement which is displayed. For example, jerks measured by the accelerometer can impact the gear train which can be shown vibrating in their simulated bearings. If the movement has a simulated oscillating mass (not shown), the oscillations of the watch may cause this displayed oscillating mass to oscillate, which can be used to reload a simulated virtual barrel and wind the watch. Likewise, the influence of gravity and other accelerations on the shape of the virtual hairspring and on the oscillations of the virtual balance can be simulated and displayed, as can the movements of a simulated vortex for example.

In an advantageous embodiment, the movement shown is a real simulation of a mechanical movement. The simulated components represented therefore have a virtual mass, and simulated torques or forces are transmitted from one component to another, for example through the gear train. Likewise, some components such as springs have virtual rigidity. The microcontroller thus calculates and displays at all times a simulation of the position of each component based on interactions with other components, acceleration and user interactions on crown 42, pushbuttons or crystal for example .

The time displayed at all times therefore results from this simulation, and can for example be disturbed by the accelerations of the simulated regulating organ or by imperfections in the movement. This time can therefore differ from the generally more precise time calculated by the microcontroller 10 on the basis of the indications of the quartz oscillator 11. In one embodiment, the time displayed by the simulated and displayed mechanical movement is therefore synchronized. with the quartz time, either automatically at regular intervals or when the difference exceeds a threshold, or manually by user interaction on one of the push buttons 41 or on the touch sensor.

It is also possible, in a variant that is simpler to produce but less realistic, to display a pure image of a movement on the screen, with a position of each component and of the hands which is directly determined from the time. quartz 11. Moreover, the same watch can offer both types of display, for example on two display modes selectable by the user.

The watch of the invention can also be used to display indications other than simulated mechanical movements. For example, the figure 5 illustrates a mode of digital representation of the current time on the screen 4. Other indications, for example other digital displays or virtual hands, calendars, images, photos, text, multimedia pages, etc. can be displayed on display 4.

The figure 6 schematically illustrates a possible arrangement of screens which allow different indications or images to be displayed. At least one screen corresponds according to the invention to the display of a simulated mechanical movement. Other screens can be selected to display other mechanical movements, or other indications related or not to the time indication.

The size of each selectable screen corresponds to the size of display 4. The user can modify the current display by permanently replacing, until the next replacement, the screen displayed by any other selected screen. .

In this arrangement, the selectable screens are virtually arranged to form a row 22 and a virtual column 21. The user can scroll through the screens in the horizontal direction, in order to replace the current screen 23 with any other. screen 220 to 225 in row 22. In the same way, the user can scroll through the screens vertically in order to choose one of screens 210 to 213 in column 21. All the available information can therefore be displayed by simply scrolling horizontally or vertically .

The scrolling of the screens in the horizontal or vertical direction is obtained by moving the finger on the glass in the corresponding direction and in the corresponding direction. Thus the user can easily consult the available screens, and choose a particular screen with simple movements of the finger in the horizontal or vertical direction.

Advantageously, the user can add screens, delete screens, modify the order of the screens in the row and the column, etc., from a particular menu of the watch or from a personal computer connected to the watch. A user can thus update a mechanical movement, or add an additional representation of a mechanical movement in an existing watch.

Each screen can be associated with a computer program or module to calculate the displayed data, and with data used by this module, for example in order to calculate and display the position of each of the components of a simulated virtual mechanical movement. For example, different screens corresponding to different mechanical movements can be associated with different computer programs making it possible to simulate these movements and display the corresponding simulations.

As indicated, each screen may display a different indication or correspond to a particular operating mode of the watch. For example, screens 220, 221, and 222 are used to display the current time in the Tokyo, New York, and Los Angeles time zones. The screens 210, 211, 212 and 213 make it possible to display the number of days, respectively hours, since a given moment, for example since birth, since marriage, quitting smoking, etc. Other maps or screens may be used to display moon phases, a calendar, or other hourly or non-hourly indications.
