`WRSTWATCH WITH A TOUCH SCREEN
`AND METHOD FOR DISPLAYING ON A
`TOUCH-SCREEN WATCH
`
`The present application is a continuation of international
`patent application PCT/EP2011/000893 filed 30 Jun. 2010,
`the contents of which are incorporated herewith by refer
`ence. It claims priority of Swiss patent application CH2009/
`1036, filed 3 Jul. 2009, the contents of which are incorpo
`rated herewith by reference.

`
`TECHNICAL FIELD
`
`The present invention concerns a wristwatch, in particular
`an electronic wristwatch having a high-resolution display
`screen and a haptic Surface.
`
`15
`
`STATE OF THE ART
`
`Usual watches with a numeric display have several seg
`ments of liquid crystals controlled selectively in order to
`display the digits or symbols corresponding for example to
`the current time. The number of symbols that can be
`displayed is limited by the configuration of the segments.
`Wristwatches with a matrix display, i.e. a display formed
`of a matrix of pixels, are also known. These displays are
`more flexible than the segment displays and enable any
`symbols or images to be displayed. The present invention is
`more particularly concerned with Such watches with a
`matrix display.
`Furthermore, wristwatches with a sheet of touch-sensitive
`glass allowing it to react to the user's finger on clearly
`identified portions of the glass are also known. Thus, U.S.
`Pat. No. 6,967,903 describes a method for controlling the
`different functions of a watch by pressing on predefined
`haptic Zones on the glass. These Zones are operated like
`buttons to trigger particular functions. This is called Zero
`dimension navigation: the haptic Surface reacts only to
`contacts on precise Zones of the glass. As the haptic Zones
`are generally transparent, it is necessary to indicate their
`position on the dial or on the bezel; the number of haptic
`Zones is thus necessarily limited by the space required for
`these indications.
`EP1394.640 describes another watch with haptic control
`having twelve sensors around the glass. The order in which
`the sensors are activated is recognized. This watch Suffers
`from the same disadvantages and enables at most twelve
`different commands to be entered.
`WO2006 111481 describes a watch with a touch screen
`presenting juxtaposed Zones that can be selectively dis
`played and that are sensible to the touch. The haptic Zones
`have the shape of the display Surfaces, which constitutes a
`serious technological limitation. In practice, one often
`wishes to promote Small-size display Zones to increase
`resolution and much wider haptic Surfaces to reduce the
`energy consumption and facilitate the connection between
`the tactile glass and the movement.
`WO03056397 pertains to a watch wherein the time is
`displayed in numeric and/or analog fashion by a liquid
`crystal display. The watch comprises several electrodes on
`the periphery of the glass and which can be activated
`separately by the finger.
`EP1511178 describes a method for manufacturing a watch
`glass with invisible electrodes forming the sensors of a touch
`SCC.
`U.S. Pat. No. 6,477,117 describes a portable device with
`a touch screen. Access to different available applications is

`gained by selecting with the finger an icon of the application
`on a virtual desktop—in the same manner as on a computer
`screen. The size of the icons that can be displayed on a watch
`screen is necessarily very limited, which causes a problem
`of ergonomics in particular for people Suffering from
`reduced visual acuity.
`One-dimensional touch screens that react to the move
`ment or position of the finger along a linear axis are also
`known. CH627615 describes for example a watch with a
`triangular-shaped capacitive electrode. The electronic circuit
`is capable of detecting the finger's position along this
`electrode. Such linear screens are typically used for control
`ling linear buttons or regulating elements, for example for
`unlocking a device or adjusting the Sound Volume.
`Finally, two-dimensional touch screens are also known
`that are capable of detecting and reacting to movements of
`the finger along two distinct directions on the screen Surface.
`By comparison with Zero-dimensional systems that react to
`the absolute position of the finger, haptic systems detecting
`the movement and/or the trajectory of the finger afford the
`advantage of a more ergonomic use. The finger can thus be
`moved to any place of the screen; it is not necessary to
`indicate the Zone that is to be activated.
`Two-dimensional touch screens use electrodes that are
`very close together, nearly contiguous. A finger laid on the
`haptic Surface generally covers variable portions of several
`adjacent electrodes. A Software computes the finger's center
`of gravity from signals Supplied by several electrodes and
`determines the finger's movement from the variation in the
`position of this center of gravity through time.
`Two-dimensional touch screens thus require electrodes
`and a signal processing circuit that are clearly more complex
`than Zero- or one-dimensional Screens; they are generally
`reserved to devices having Sufficient processing power and
`energy Supply, for example portable computers, PDAs and
`more recently many portable telephones. These devices have
`screens with a clearly greater Surface than that of a watch
`glass; even a mobile telephone has a considerably greater
`surface than that of the largest conceivable watches. These
`large screen sizes enable graphical interface elements, for
`example several icons, menu bars etc., to be displayed,
`which it is nearly impossible to represent on a wristwatch.
`The navigation between the different programs or docu
`ments in the graphical interface of a wristwatch raises very
`specific problems that are different than those that arise with
`a screen that is even slightly larger.
`Watches are usually considered too small to allow or
`require a movement of the finger to be detected. Further
`more, there is a bias in the watch-making industry against
`Sophisticated touch screens, whose necessary energy con
`Sumption, refresh time or computer power are dreaded.
`Furthermore, watch screens are generally considered too
`small to allow functions to be selected by means of icons or
`other widgets that are frequently found in graphic user
`interfaces of computers or mobile telephones.
`Because of these biases, and because the usefulness of
`detecting a movement on a watch glass with a reduced
`Surface is not obvious, watches with digital displays are not
`provided with two-dimensional haptic surfaces nor with
`Software enabling a movement of the finger along two
`directions to be detected.
`Furthermore, one also distinguishes between single touch
`haptic Surfaces (mono-haptic) and multi-touch (or multi
`haptic) surfaces. A multi-touch Surface is understood in the
`present application to refer to a haptic Surface or touch
`screen capable of detecting several simultaneous contact
`points, for example simultaneous movements of several
`
`

`

`US 9,651,922 B2
`
`3
`fingers on the haptic surface. The electrodes of these devices
`are usually associated to a circuit or a software that interprets
`these simultaneous contacts and converts them into com
`mands for a graphical user interface.
`Thus, EP1808751 describes a watch with L-shaped
`capacitive haptic keys that are dimensioned so as to allow
`the finger to select simultaneously one or two adjacent keys.
`This watch enables the contact of one finger on two adjacent
`electrodes to be detected, but not the contact of two distinct
`fingers on electrodes further apart; it is thus not a multi
`touch screen.
`There is also a bias in the state of the art against using
`multi-touch screens in wristwatches, whose glass is gener
`ally considered too small to allow the contact, or even more
`the simultaneous movement, of several fingers.
`A limited number of documents however describe wrist
`watches that allow commands to be entered by moving the
`finger on a tactile glass.
`U.S. Pat. No. 7,170,996 describes a data input system for
`a compact electronic apparatus enabling notably characters
`to be selected in a matrix with the aid of different move
`ments of the finger. The proposed solution only makes it
`possible to navigate in a specific menu prepared to this
`effect; data entry requires tedious training.
`U.S. Pat. App. No. 2006/0092.177 describes a watch with
`a sensor in each corner allowing different commands to be
`entered by selecting one of the sensors or a sequence of
`sensors actuated in a particular order. One of the commands
`makes it possible to display a "card' presenting comple
`mentary information, for example a list of received mes
`sages, a list of alarms, etc. This card is displayed during a
`30
`limited period of time and disappears automatically after a
`short while. However, the arrangement of non-contiguous
`electrodes suggested in this document makes the command
`inputting less intuitive; this is not a two-dimensional haptic
`Surface. The user must move his finger accurately on the
`haptic Surfaces and a finger moving across the center of the
`glass will not be detected. Complex and hard-to-remember
`selection sequences must be used to access the different
`functions offered. The number of subsidiary functions that
`can be displayed is limited by the number of sensors.
`There is thus a need in the prior art for a wristwatch
`provided with a tactile (i.e., touch-sensitive) glass making it
`possible to enter commands without having to press on a
`particular Zone of the glass.
`There is in particular a need for a wristwatch allowing
`movements of a finger on a touch screen to be detected.
`In particular, there is a need for a wristwatch of which at
`least certain elements, including the haptic Surface, the
`signal processing circuit coming from the electrodes of this
`Surface, the processor and the graphical interface, are
`adapted to the particular constraints of a wristwatch, in
`particular the reduced surface of the screen and the very
`strict requirements in terms of electric consumption and
`computation power available.
`There is also a need for a wristwatch enabling a large
`number of different indications to be displayed without
`however cluttering up the display. This watch should fur
`thermore afford easy and intuitive access to different avail
`able items of information by means of commands that are
`easy to learn and to enter on a touch-sensitive (tactile) glass.
`There is also a need for a wristwatch that allows the type
`of information displayed and the manner in which this
`information is presented to be customized.

`
`a digital matrix display;
`a sheet of touch-sensitive glass provided with a plurality
`of electrodes;
`a processing circuit laid out so as to interpret the signals
`from said electrodes, for selecting a card from among
`several available cards depending on these signals and for
`displaying said card on the entire digital matrix display;
`wherein said touch-sensitive glass is a two-dimensional
`touch-sensitive glass for detecting the movements of at least
`one finger along at least two different directions;
`wherein the processing circuit is programmed so as to
`cause cards to scroll past in order to lastingly replace the
`initially displayed card with another card,
`wherein the scrolling direction depends on the direction of
`said movement.
`In the present description, the term “card” describes a
`control, or widget, displayed on the watch's graphical inter
`face to represent on the entire screen a unit Such as the
`current time, a phase of the moon, a chronograph display etc.
`A card comprises a screen background image designed to
`occupy the entire watch screen; this image can be fixed, for
`example for displaying a photograph, or periodically
`refreshed, for example for displaying the current time. The
`card can furthermore be associated to a function (computer
`program or module) determining the indications displayed
`on the screen background; for example, a card can be
`associated to a program computing and displaying, in a text
`or graphic form, the phase of the moon. A card can further
`more define the behavior of the haptic interface and the
`functions or modules that are to be launched depending on
`the movements of the finger on the screen.
`Thus, navigating in the watch's graphical interface is
`achieved by having virtually juxtaposed cards scroll past, so
`as to replace the entire image of one card by another image
`corresponding for example to a card and for displaying
`another function. It is thus possible to avoid the disadvan
`tages of conventional graphical interfaces in which the
`launching of programs or functions is achieved by selecting
`a minuscule icon of the program on the screen background.
`Here, the icons are replaced by cards that generally occupy
`the entire screen and that display the useful information.
`These cards can be customized by the user, who also has
`the option of adding new cards from an external computer
`connected to the watch, in order to add new functions and/or
`to modify the way in which an indication is displayed.
`The invention is also based on the observation that the
`number of different movements the users are able and
`willing to learn in order to operate the watch is limited. To
`this effect, the watch's Software is advantageously con
`trolled mainly or even exclusively with the aid of horizontal
`or vertical movements of the finger on the glass. Most of the
`watch's functions, or even all its functions, can thus be
`accessed with these two very simple commands.
`The touch-sensitive glass enables the movements of the
`finger in a horizontal or vertical direction to be detected in
`a reliable manner without the user having to go over specific
`electrodes to enter a given command.
`In one embodiment, tap commands (brief contact of the
`finger on the glass) or double tap commands (two brief
`contacts in quick Succession) can also be entered, for
`example to confirm a command or launch a function, in a
`manner similar to the click and double click performed with
`the mouse of a computer graphical interface. These com
`mands can, depending on the case, be entered on clearly
`displayed Zones of the screen for example on a “START
`button in chronograph mode—or anywhere on the screen.

`
`BRIEF SUMMARY OF THE INVENTION
`
`According to the invention, these aims are achieved
`notably by means of a wristwatch having:
`

`
`

`

`US 9,651,922 B2
`
`5
`The wristwatch also has the advantage that it is very easy
`to switch from one card to another by simple horizontal or
`vertical movements of the finger on the glass in order to
`cause juxtaposed cards to scroll past.
`The scrolling past from one card to another can for
`example correspond to a mode switch of the watch. For
`example, the switch from a “display of the current time'
`mode to a “display of another time Zone' mode is achieved
`by cards scrolling past and by replacing the entire image
`displayed on the watch screen with the image of another
`card.
`The present invention also concerns the organization of
`the cards and the method used for the card Scrolling so as to
`render the operation as quick and intuitive as possible.
`In the present text, the “horizontal direction of the watch
`corresponds to the 9 o'clock-3 o'clock direction on the
`dial of a traditional watch; the “vertical direction is parallel
`to the 6 o'clock-12 o'clock direction.

`
`EXAMPLE(S) OF EMBODIMENTS OF THE
`INVENTION
`
`6
`The bracelet 2 can for example be made of rubber or of
`any other suitable material. In one embodiment, it comprises
`additional indicators, for example LEDs or an LCD screen,
`embedded in the bracelets material and enabling comple
`mentary indications to those of the matrix display 4 to be
`shown. The indicators are preferably powered and con
`trolled by the watch's processing circuit (not illustrated) and
`allow for example indications relative to the state of the
`watch (for example the battery charge level) or time indi
`cations depending on the current display (for example a
`number of timed laps) to be displayed. There is thus an
`electric connection between the bracelet's indicators and the
`electronic watch movement.
`The glass 3 closes the upper Surface of the case and covers
`the digital matrix display 4. It is preferably made of sapphire
`or of another scratchproof material and is coated with an
`anti-glare treatment. In a preferred embodiment, the glass is
`cylindrically, or possibly spherically, cambered.
`Transparent electrodes are placed in or under the glass 3
`in order to detect the presence of a finger or of a stylus. The
`detection technology preferably uses methods known in the
`state of the art, for example a capacitive detection.
`A high-resolution digital matrix display 4 occupies nearly
`the entire surface under the glass 3 and thus serves both as
`watch dial and as time indicator. In a preferred embodiment,
`the display is constituted by a color liquid crystal display
`(LCD or TFT-LCD) with at least 150x150 pixels. Other
`types of display, including displays based on the OLED
`technology for example, can also be used. Furthermore, the
`watch could also have several displays, for example several
`digital displays, or a digital matrix display combined with
`hands or other mechanical indicators.
`The mentioned processing circuit enables the signals
`coming from the electrodes to be interpreted and indications
`depending on these signals to be displayed on the matrix
`display 4. The processing circuit typically comprises a
`microcontroller for controlling the matrix display, another
`microcontroller for controlling the haptic interface, and a
`general microcontroller for determining the indications to be
`displayed at each instant, depending on the card selected.
`These microcontrollers can also be grouped differently.
`An input-output circuit, for example a USB decoder or a
`BLUETOOTH (US registered trademark) or ZIGBEE (In
`ternational registered trademark) receiver, can also be pro
`vided.
`The processing circuit is specifically arranged to interpret
`the signals from said electrodes, to select a card from among
`several available cards depending on these signals, and to
`display said card on the whole of said digital matrix display;
`this arrangement is preferably achieved by storing in the
`microcontroller's memory a computer program (firmware)
`allowing this specific operation to be controlled. The firm
`ware causes the cards to be displayed including images
`stored in a memory and that are reproduced on the display
`4. Advantageously, the Software and/or data used by this
`software can be modified or updated by the user, for example
`through the USB, BLUETOOTH (US registered trademark),
`ZIGBEE (International registered trademark) or other inter
`face mentioned further above. This interface makes it pos
`sible for example to load new cards or new images used on
`these cards and to thus customize the cards and the graphic
`elements represented on these cards.
`The size and the resolution of the display 4 are sufficient
`for displaying simultaneously several indications on the
`same card, for example the current time in FIG. 1A or the
`current time and the phase of the moon in FIG. 1B. In order
`to extend the watch's functionalities, the user can switch

`FIGS. 1a and 1b illustrate two embodiments of a wrist
`watch 1 according to the invention. The illustrated watch
`comprises notably a bracelet 2 and a case 5 provided with a
`glass 3 covering a digital matrix display 4.
`The case 5 can comprise control elements, for example
`push-buttons, a crown etc., that are however not indispens
`able to the operation; in a preferred embodiment, the watch
`has no crown and is provided only with push-buttons (not
`represented) for Switching the screen on or off or to adjust
`its luminosity. A luminosity sensor enabling the intensity of
`the screen to be automatically adapted to the Surrounding
`luminosity can also be used as an option. The watch can
`switch nearly instantly from a stand-by mode, where the
`display is switched off or at least less luminous, to a “time
`reading and/or navigation mode, for example as soon as the
`glass is touched or following a tap or double tap on the touch
`SCC.
`The case 5 can also comprise a connector to connect the
`watch to an external computer, for example a micro or nano
`USB connector on the bottom or in one of the watch's sides.
`Wireless connection means, for example a ZIGBEE (Inter
`national registered trademark) or BLUETOOTH (US regis
`tered trademark) module, can also be provided.
`The watch is advantageously powered electrically by
`means of a rechargeable accumulator through a micro or
`nano USE connector, of a specific or proprietary connector
`or, in a variant embodiment, through a radiofrequency
`interface.

`from one display mode to another and for example replace
`the card displayed in FIG. 1A by the card of FIG. 1B.
`FIG. 2 illustrates diagrammatically a possible arrange
`ment of cards according to one embodiment of the invention.
`Each card corresponds to a virtual screen and enables
`indications and/or images depending on the card to be
`displayed. The size of the card corresponds to the size of the
`display; the total surface available thus corresponds to the
`sum of the surface of the cards, i.e. a multiple of the display
`Surface. The user can modify the current display by replac
`ing lastingly, or until the next replacement, the displayed
`card with any other card selected from the list of available
`cards.
`In this arrangement, the cards are arranged virtually so as
`to constitute a row 22 and a virtual column 21 of cards. The
`user can make the cards Scroll in the horizontal direction, in
`order to replace the current card 23 with any other card 220
`to 225 of the row 22. In the same way, the user can make the
`cards scroll vertically in order to select one of the cards 210
`to 213 of the column 21.
`Scrolling the cards in the horizontal or vertical direction
`is achieved by moving the finger on the glass in the
`corresponding direction. Thus, the user can easily consult
`the cards available and choose a particular card with simple
`movements of the finger in the horizontal or vertical direc
`tion. The number of cards in the column 21 and in the row
`22 is limited only by the memory capacity of the watch.
`The user can advantageously add cards, delete cards,
`modify the order of the cards in the row and in the column
`etc. from a particular menu of the watch or from a personal
`computer connected to the card. Each card can be associated
`to a computer program or module for computing the data
`displayed and to data used by this module, for example a
`screen background image or user preferences stored in the
`watch. The user can also add his own images as background
`35
`or illustration in existing cards or add cards with his own
`images.
`As indicated, each card can display a different indication
`or correspond to a particular mode of operation of the watch.
`For example, the cards 220, 221 and 222 are used for
`40
`displaying the current time in the time Zones of Tokyo, New
`York and Los Angeles. The cards 210, 211, 212 and 213
`make it possible to display the number of days, respectively
`of hours, since a given instant, for example since birth, a
`wedding, the last cigarette etc. Other cards can be used for
`displaying the phases of the moon, a calendar or further
`indications of time or other. Furthermore, different cards can
`be distinguished only by graphical characteristics, for
`example a background image, or a particular representation
`of the displayed data. For example, a card could display the
`time with alphanumeric symbols as in FIG. 1A, another card
`the same time with hands drawn with pixels on the display,
`and a third card with a graphic representation by means of
`sequences of colored symbols whose number corresponds to
`the hour and to the minutes of the current time.
`Organizing the cards in a cross shape makes it easier to
`scroll and search the cards. Advantageously, when the cards
`of the column 21 Scroll past Successively on the display, the
`row 22 is not altered; the user can thus always switch to card
`223 by simply scrolling to the left, whatever the card
`currently displayed within the single vertical column 21. In
`the same way, the user can always access directly, with a
`single vertical command, any card of the column 21, what
`ever the card currently displayed within the single row 22.
`As the cards Scroll past very quickly, this organization
`enables any card to be found easily, even if the number of
`proposed cards is high. By comparison with a matrix orga

`nization, it is thus possible to avoid the risk of the user
`having to perform several Successive Scrolling operations or
`of him failing to find again a particular card.
`Exceptions are however possible, for example if they
`make it easier to switch from one card to another related
`card. Thus, in the example of FIG. 2, selecting the card 224
`from within the horizontal row 22 allows the related card
`2240 to be reached directly with a vertical scrolling com
`mand. This exception is useful for example to display
`successively different weeks or different months of a calen
`dar from a particular page of the calendar.
`Other card arrangements are also possible; for example, it
`would also be conceivable to have a card matrix with for
`example all functions linked to birthdays in one column, all
`functions linked to the moon in another column etc. and a
`horizontal navigation on the central row for the main menu.
`In another embodiment, switching from the card 224 to
`the card 2240 (for example) is achieved with a different
`touch command—for example an oblique movement, a tap,
`a double tap or a long pressure that can be made anywhere
`on the glass, or by selecting a particular Zone of the image.
`The cards of the row 22 and/or of the column 21 can
`advantageously be organized in closed loops; continuing to
`scroll beyond the last card will thus lead back to the first one
`and vice-versa. The user therefore has the impression of
`cyclically running through cards arranged on the Surface of
`a rotating cylinder or sphere.
`In another embodiment, entering a scroll command on the
`touch screen always causes a return to
