Abstract:
A wristwatch linear time display (32) is disclosed which can be read at a glance and requires very little display space. Additional functions are described which use the remaining surplus display space. These functions substantially increase the usefulness of wristwatches. Devices for the wearer to interact with the added functions are disclosed. 
     The compact time display (32) may be located where it can be seen without turning a wrist. It may also be combined with other temporal displays to improve display clarity by eliminating clutter.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates to wristwatch display of information providing the time, display showing other than the time, and the interaction of the wearer with the displays unrelated to time. 
     Conventional analog watches with hands can be read at a glance if accuracy is not desired. Conventional digital watches povide accuracy but do not graphically show the current moment&#39;s position in the time span. Watches with both analog and digital displays require the wearer to ignore the digital display when glancing and observe both displays when accuracy is desired. 
     Analog watches with hands use almost all of the display space available. Adding digital and calendar data display to them substantially detracts from their clarity. Digital watches with multiple displays are cluttered. Those with calculator and memo functions increase the clutter to the degree that concentration is required when looking for the time. 
     Diversional displays presenting random shapes are not available. Game displays for the wearer to interact with are not available. Data processing is not available. Data transfer with external storage during wearer interaction with the display is not available. 
     OBJECTS AND ADVANTAGES OF THE INVENTION 
     It is the general object of this invention to make it possible to add useful functions to wristwatches. This has been done by improving the time display and decreasing the space required to display it. This improved compact time display is the prerequisite for the following objectives: 
     1. To provide display space for games and other amusements with random action that the wearer can interact with. 
     2. To provide: Display space for data and data processing. 
     Watchband data and energy storage. 
     A receptacle for connecting to external storage. 
     3. To provide an interactive control keyboard that fits within the limited space available on a wristwatch with a large display. 
     4. To provide a time display that the wearer can see without turning a wrist. 
     5. To provide additional temporal displays alongside the basic time display in an uncluttered and easily read arrangement. 
     These objects substantially increase the services a wristwatch supplies to the wearer in addition to simplifying the reading of time. Further objects and advantages of my invention will become apparent from a consideration of the drawings and ensuing description. 
     SUMMARY 
     This simple idea of displaying an indicator that traverses a linear path each hour, and thereby shows the time remaining in an hour at a glance, provides the opportunity to increase the usefulness of a wristwatch. A digital time display in line with the linear hourly traverse display supplies accuracy in the smallest possible space. 
     This compact linear time display can be located along one side of the display surface or on the periphery of the watchcase. It can be seen by the wearer without turning a wrist if it is located on the periphery facing the wearer. The remaining unused display surface is available for other displays. 
     If no additional display is desired the linear time display with a narrow watchband provides the minimum in wristwatch size. Adding a parallel linear analog hour display and a parallel linear analog day display eliminates the clutter evident on current watches with multiple displays. 
     The compact size of the linear time display makes it possible to provide practical wearer watch interaction since the display and keyboard space required for it is available. Some of the functions that can be added are: 
     Entertainment- games, aphorisms, activities. 
     Business &amp; technology- data display &amp; storage, computing. 
     Travel- dictionaries, schedules, names, exchange rates. 
     Random action displays with provisions for the wearer to interact with them are possible. Watchband data storage, devices to use it, and a receptacle to connect with external stores are provided.

     DESCRIPTION 
     FIG. 1 is a plan view of the simplest of the embodiments showing a wristwatch having a watch face 8 containing a relatively narrow compact time display 10, enclosed by a surround or border 11 and including a digital time display provided as hour digits 18 and minute digits 16 at opposite ends of and in line with an analog hour progress display 12. The analog hour progress display 12 includes an analog hour progress indicator 14 which moves along a substantially straight route 13 from one end to the other end of the analog progress display 12. As seen in the figure, analog hour progress indicator 14 is close to the end of its traverse from the hour digits 18 to the minute digits 16. The space between it and the minute digits shows the portion of the hour remaining. Indicator 14 in the liquid crystal display shown moves from electrode to electrode in steps. All of the displayed steps can be retained if desired. Bar graph displays are available if preferred. Accuracy is supplied with the minute digits. The LCD alphanumeric displays can be switched to seconds or calendar display when desired. As seen in the figure, indicator 14 has a dimension traverse to route 13. Hour digits 18 and minute digits 16 adjoin analog progress display 12 at opposite ends thereof and have substantially the same dimension as indicator 14 transverse to route 13. 
     FIG. 2 is a plan view of a multiple display linear digital-analog wristwatch. The hour progress display 12 includes route 13 and an indicator 14, which traverses along route 13 as described for FIG. 1. The hour digit 18 display is no longer aligned with analog hour progress display 12, but traverses along a second linear display 19 from top to bottom every twelve hours, thereby continuously displaying the current hour and the portion of the day that has elapsed and the portion that remains. A day of the week display 20 similarly traverses along a third linear display 21. The date is shown digitally below the day. The linear watch displays the progression of the week in an orderly uncluttered manner. 
     The linear displays shown are straight. They can be curved in an arc, an &#34;S&#34; shape, or free form for aesthetic reasons or for conformance with the watchcase. The reduction in space required is the same. 
     FIG. 3 is a plan view of a multiple display linear digital-analog interactive wristwatch. Compact time display 10 is positioned on a sloped surface 32, adjoins a portion of the periphery 9 of watch face 8 at one side thereof and extends over only a minor portion of the watch face. This makes the remaining major portion of the watch face, which is unencumbered by compact time display 10, available for other functions as shown at 24 and 28. The displays in this view are foreshortened because they are not parallel with the plane of the view. The time display 10 is readable even though it is foreshortened. The nontemporal display 28 space is clearly not needed for time display. 
     FIG. 4 is a side view of the watch of FIG. 3. The time display on slope 32 is on the periphery of the watch where it faces the wearer without turning a wrist. All of the displays are placed at 45 degrees. The angle chosen is optional. 
     FIG. 5 is the wearer&#39;s view of the watch of FIG. 3. The bottom display shows the time display on slope 32 with the analog hour progress indicator 14 traversing the space between the hour digit 18 and the and the minute digits 16. The simplicity of this time display is most apparent here. You have it if you separate the hours 18 from the minutes 16 in a conventional digital display and use the blinking colon as the traversing hour progress indicator 14. 
     The center temporal display 48 shows the day, month, and date. It can be a second nontemporal display 28 or added to the top nontemporal display 28 since the complete time display on slope 32 is provided below it. 
     The dancers in the top display appear at random; singly or in multiples. Their limbs can move by switching electrodes in an LCD. The wearer can alter tempo, rhythm, or the sequence of appearance with an interactive control 52. Basketball displays can be provided with interactive blocking and sinking of shots. 
     FIG. 6 is a plan view of a compact time display 10, incorporating analog hour progress display 12 adjoining digital hour display 18 and digital minute display 16, on a mechanical wristwatch. The ancillary temporal display 48 such as day, date, and seconds are under a flip up cover 54. The analog hour progress indicator 14, an arc, is clearly visible as is the hour digit 18. Compact time display 10 adjoins a portion of the periphery 9 of the watch face 8 at one side thereof and extends over only a minor portion of the watch face. This makes the remaining major portion of the watch face, which is unencumbered by compact time display 10, available for other functions, such as the ancillary temporal display 48. 
     The peripherally located linear digital-analog time display can be included as an additional feature on a conventional analog wristwatch. A roulette wheel can be put under the cover. 
     FIG. 7 is the side view of the watch of FIG. 6 showing the peripherally located time display on slope 32. The display is less exposed to damage and is therefore a better choice than conventional watches for those wearers who are physically active. A protective ridge or hood above the display can be added to further decrease the chance of damage. 
     FIG. 8, the wearer&#39;s view of the watch of FIG. 6, shows the hour digit 18 centered in the display. The hour display 18 moves in jumps of an hour. Several mechanisms are available to do this. 
     The analog hour progress indicator 14 can visually standout by contrast and color from the background display so that it can be read at a glance. The minute index mark 46 is used for accuracy. The mechanical drive for the coned disks bearing the time display on slope 32 present no challenge for anyone familiar with mechanical time pieces. 
     FIG. 9 is the preferred embodiment of the linear digital-analog interactive wristwatch. The relatively narrow compact time display 10 is located horizontally on sloped surface 32 and comprises analog hour progress display 12 having analog hour progress indicator 14 extending across straight route 13, which extends from one end of compact time display 10 to the other end thereof. Digital hour display 18 and digital minute display 16 adjoin analog hour progress display 12 and are positioned just above route 13 so that the effective width of compact time display 10 is established by the combined height of indicator 14 and digital displays 18 and 16. Compact time display 10 adjoins the lower side of the periphery 9 of the watch face 8 and extends over only a minor portion of the watch face, the remaining major portion of the watch face being unencumbered by compact time display 10 and being available for other functions. 
     These include a keyboard 38, a display screen 34, and mode keys 40. The keyboard 38 has the full alphabet, ten digits, and + -× +. Mode keys 40 can switch keys to different functions. Other mode keys can input and access storage, actuate remote storage, and set the time. The time display on slope 32 in this plan view is foreshortened but still readable. 
     FIG. 10 is a side view of the watch of FIG. 9. The time display on slope 32 is located on the periphery of the watchcase facing the wearer. The watchband 26 shown would be custom fitted to the wearer. The data storage can also be contained in small packets attached to a conventional watchband. The external connector receptacle 42 is shown. 
     FIG. 11A and FIG. 11B show the recessed keys 36 of the watch of FIG. 9. The keys are designed to be depressed with a pointed probe inserted into the recess shown. Keys 36 have a sloped surface 37 on which key identification 50 is located above the probe&#39;s contact point to prevent wear from decreasing legibility. By placing key identification 50 on sloped key surface 37, the area of the watch face needed for the identification of the keys is reduced. The higher location is also more visible to the wearer. Keys 36 with more than one identification have dual functions which are activated with mode keys 40. There are forty input keys 36 shown and four mode keys. This provides the potential for 160 different inputs. The interactive performance of the wearer with the watch during data processing is substantially enhanced by using a pointed probe and recessed keys. Data processing on a wristwatch is impractical without them. 
     FIG. 12 shows the wearer&#39;s view of the time display 32 on the watch of FIG. 9. The analog hour progress indicator 14 is a series of dashes in this display. There is space above the dashes to momentarily show calendar data 48. 
     While my above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of the embodiments thereof. Many other variations are possible. For example, the mechanical watch of FIG. 6 can have an LCD linear time display as described herein on the periphery facing the wearer. Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
