The present invention relates to languages and devices for visual representation of the passage of time, and specifically to a clock that is especially suited to children.
Devices for the visual portrayal of the passage of time range from concrete instantiations of slow-moving physical phenomena such as sundials and hourglasses, to more arbitrary paradigms developed along with specific motion or display technologies, i.e. dial clocks and digital clocks. These arbitrary representations have long survived the original mechanism that generated them and moved into the realm of language, retaining their meaning in relation to the time of day regardless of how the visual image is generated. Thus we may prefer a “digital” or “dial” clock interface on the screen of our computer or on our wrist, as a matter of taste and legibility. The mechanism that generates the changes in the visual portrayal can be based on atomic decay, piezoelectric pulses, mechanical action or any other phenomenon without affecting the resulting language of representation. The two dominant languages of dial and digital clocks, though arbitrary, are well enough accepted to perform the role of semiotic sign or marker throughout most of the world.
There have been many suggestions for variations on and alternatives to the two dominant languages, to improve legibility, aesthetics, or other factors. The prior art includes novel ways of representing hours, minutes, and other accepted divisions of time. Conceivably, displays could be based on other divisions of time or represent the flow of time without representing divisions per se.
The standard systems of representing time are dependent on familiarity with visual representations of numbers and comprehension of the clock hands as indicators within an otherwise static interface. Such interfaces are a priori unsuitable for children. Understanding the standard time representations requires a stage in child development more advanced than the stage at which a child can grasp the concept of the passage of time. Due to this misalignment, there is typically a protracted stage during which a child can grasp some of the concepts of time, but is prevented from doing this due to the difficulties of parsing written numerals and understanding the meaning of the position of the hands.
In the prior art are known devices and methods that attempt to make time telling easier for children. A review of earlier art will serve to illustrate their respective and collective lacunae.
U.S. Pat. No. 2,493,138 to Hathaway describes a time teaching device in the form of a standard clock with an attached verse-inscribed panel. The numeral indicia are augmented with pictures of animals and familiar objects and the hands of the clock are fashioned in the form of the storybook characters Jack and Jill. Hathaway teaches a working version with clockwork driven hands as well as a demonstration version in which the hands are only turned manually. The verses inscribed on the device refer to the pictures and the characters on the hands of the clock, relating them in storybook fashion to the hours of a child's day. Hathaway does not teach a new method of representing time, but merely attaches additional recognizable shapes to the sectors of the clock and to its hands. The cognitive steps necessary to differentiate between the two hands of the clock and to associate the location of the hand with a particular sector of the clock face are retained.
U.S. Pat. No. 5,526,327 to Cordova, Jr. describes a display and method for depicting the passage of time by selectively and progressively “filling” predetermined areas representing hours, minutes, seconds, and tenths of seconds. A user tells time by noting how much of a given area is filled. The display is configured in a variety of shapes with the possibility of assigning different parts of the shapes to the various time divisions. While Cordova teaches a new method of representing the passage of time, no improvement in legibility or comprehensibility is achieved.
A further disadvantage of Cordova is the inherent inaccuracy of depiction. The user is expected to calculate the relation of part to whole in determining hours on a 12 or 24 hour scale. This is cognitively difficult and can easily result in reading inaccuracies of one or two hours. A further disadvantage is in the depiction of small time divisions such as proposed for seconds or tenths of seconds. A device according to Cordova represents the passage of time over short intervals by rapidly flashing lights, detracting from the legibility and clarity of the entire display.
U.S. Pat. No. 5,044,961 to Bruskewitz describes a portable child activity timer designed to be comprehensible by children. A device according to Bruskewitz indicates pictorially what activity is being timed or what the child is waiting for, in addition to showing numerically how much time is left and indicating by means of a sound when a timed period is over. A device according to Bruskewitz is useful only for timing specific intervals and does not propose a new method of representing the time divisions of a day. The pictures on the timer relate to specific situations or events and are not associated with the time of day in a general sense.
Other devices configured to teach children time telling skills are found in Swiss Patent 540 542 to Ingold, U.S. Pat. No. 3,608,214 to Rancati, U.S. Pat. No. 3,967,389 to Brooks, U.S. Pat. No. 4,124,945 to Totten, and U.S. Pat. No. 4,219,943 to Grimes, all of which describe variations on the concept of time telling teaching devices or teaching clocks. These devices are not actual clocks, but rather teaching aids consisting of various discs, rings, and hands with printing, pictures and colors on them which are rotated manually around a central pivot in order to display a simulacrum of a clock face. Although colors are used to represent the various hours in a day, the devices teach no new time-telling language.
Thus, there is a need for, and it would be greatly advantageous to have a clock designed for children that familiarized them with the concepts of the passage of time, telling time, and associating given visual images with times of the day, using familiar images and colors to represent time. In addition, there is a need for, and it would be greatly advantageous to have a method of representing and telling time that is comprehensible and accessible to any person that is developmentally able to recognize images and colors.
The current invention provides a device that uses an alternative language of visual representation of the passage of time that is readable and comprehensible by any user, and in particular readable at the earliest possible stage of child development.
The current invention is of a clock that uses color and recognizable images to represent both the passage of time and the time of day in a form that is comprehensible to young children. For example, sections representing the 12 or 24 hours are arrayed around the circumference of a circular face as in a conventional clock face. However, instead of using hands to indicate the hour, the appropriate hour is indicated by an area of color that appears in an appropriate section. Each section of roughly 30° representing an hour has a graphic representation, for example of a recognizable character such as an animal, which remains fixed in place.
At least part of each graphic representation is transparent, such that a part of a colored disc placed behind the clock face is visible through these transparent sections or windows. The term “window”, when used within this specification and subsequent claims, refers to a section of a component of the embodiment through which a more distant component is visible, irrespective of whether the more distant component is viewed through an open perforation in the nearer component or through a transparent section of the nearer component.
This colored disc is divided into areas of various colors which represent minutes or other subdivisions of time. The colored disk rotates, bringing successive colored areas into view through each of the windows of the characters. In this way, a time of day is represented by the association of a particular color with a particular recognizable character, for example, a yellow dolphin or a blue cat. The time resolution of the clock of the present invention as represented by the change of colors may vary. One embodiment of the invention is described where the colors change every 10 minutes, but it is clear that these intervals could be 5 minutes, 12 minutes, or any other period of time (but generally at least half of a long time period: thus if a long period was 1 hour, each short time period would be about 30 minutes or less). A further increase in resolution may be achieved by varying the pattern or intensity of the color on the color wheel or by progressively filling the area with color. In any case, the accuracy and precision of the timekeeping mechanism of the clock will be on the order of seconds or fractions of seconds in keeping with standard clock technology, and options will exist for displaying a concurrent readout of the time at a finer resolution than is represented by color alone. This concurrent readout enables proper setting of the clock, and offers a higher precision to those able to read it. A preferred embodiment of the current embodiment supplements the color-based display with an accurate minute display indicated by one or more sets of numbers printed on the color wheel.
In one preferred embodiment of the invention, a third separately rotating masking disc is disposed, for example, between the rotating colored disc and the fixed character disc, alternately screening and revealing the rotating colored disc in successive characters. This selective revealing could also be accomplished by placing the third masking disc behind translucent or transparent front discs and providing for natural or artificial lighting from behind the clock. This selective revealing could also be accomplished by other electrical or electrochemical or mechanical means.
In another preferred embodiment of the invention, a fourth activity disc, situated, for example, in the center of the clock face, is divided into sections with depictions of activities appropriate to different times of the day. This disc is also partially masked by the clock face, and rotates to consecutively reveal successive depictions. The rotation of the activity disc is continuous or discrete and, in some preferred embodiments, is programmable. At any moment, the activity disc shows one of a series of activities associated with a particular time of day.
Another preferred embodiment of the invention is readable by blind or visually impaired persons of all ages, while particularly adapted to children. In this preferred embodiment, the color disc is replaced by a texture disc that has varying tactile properties in separate areas. The masking disc and front face of the clock are necessarily perforated in this embodiment such that a person touching the face of the clock can feel the varying tactile properties of the texture disc behind. In this preferred embodiment, the characters on the face of the clock have a three-dimensional or otherwise tactilely distinguishable nature. As a further feature, auditory cues associated with particular times could be added to this or other embodiments.
The current invention overcomes the shortcomings noted in the prior art and provides a clock readable by anyone who has the ability to remember and recognize colors and figures such as animals. It is particularly suited for children and designed to provide both a useful representation of time, and a transitional educational tool to facilitate telling time with other methods. Unlike some previous examples, the current invention provides an actual functional clock that is accurate and consistent from day to day.
In addition, the present invention provides a clock for children that consistently associates a given recognizable image with a certain time such that the image/time sign or association is recognizable outside of the context of the clock face. Such an image can be used in other media directed towards preliterate children. For example, advertisements for upcoming television programs could carry an image indicating the time according to the time telling language of the present invention.
As is the case with any two-dimensional visual portrayal, the proposed language and its varying signs can be implemented on a computer display. Without ruling out computer displays or other electronic displays as a means of representing the proposed time telling language, a preferred embodiment of the present invention provides a stand-alone mechanism that represents the passage of time using the language of the present invention.
In addition, the proposed language is suitable for reproduction and use in other conventional methods of printing and publishing. Some of the more useful instances of such publishing are as a bulletin board or magnetic board with movable figures designed to teach the proposed language. A book that teaches the proposed language could be static or include moving parts that reproduce the rotary mechanism of the proposed invention. Likewise, a nonfunctional mock-up of a clock according to the current invention could be produced for use as an educational tool.
Any of these solutions could also use standard revolving clock hands as in those of a standard timepiece in addition to the described language as a transition device between the two languages of portraying time. The phrase “standard timepiece”, when used within this specification and subsequent claims, refers to a rotary dial clock or watch that uses the familiar method of revolving hour and minute hand indicators to point to sectors of the clock face.
An additional preferred embodiment of the invention provides in addition to the main clock, a second device that uses two or more conventional clock hands to indicate an active graphic representation and an active color. The second device is useful for translating between the two systems of portraying time (the standard clock system and the system of the present invention), and is especially well suited for use as a parent's watch to aid in quick translation of time concepts between the two portrayals.
Thus the present invention provides for a second device which is substantially a standard timepiece having a face, an hour hand and a minute hand with a plurality of graphic representations radially distributed about the face, each graphic representation associated with an hour wherein the distribution of graphic representations is such that at any moment the hour hand substantially indicates a single individual graphic representation. In such a way, an adult user of the second device sees that the hour hand substantially points at, for example, a lion in the proximity of 12 o'clock and recognize that a lion is associated with the time period between 12:00 and 12:59. Further the second device of the present invention has a color-indication system associated with the minute hand, wherein a distinct color is associated with a time division, the time division being less than one hour. It is clear that the time division corresponding to each color of the second device is of a length equivalent to a corresponding children's clock of the present invention.
In one feature of the present invention, the association of the color indication system with the minute hand is a change of color of a part of the second device and the change of color is dependent on an orientation of the minute hand. For example, a LED capable of producing four different colors lights-up in a color according to the orientation of the minute hand, a first color for when the minute hand indicates the first quarter of an hour, a second color when the minute hand indicates the second quarter of an hour, a third color for when the minute hand indicates the third quarter of an hour, and a fourth color when the minute hand indicates the fourth quarter of an hour. Advantageously, the color change is of the minute hand itself.
In another feature of the present invention, the association of the color indication system with the minute hand is by an arrangement of colors radially distributed about the face of the second device (see
According to the teachings of the present invention there is provided a device for indicating the association of times of day with events having a display substrate (e.g. an electronic displays, a bulletin boards a magnetic board (a board to which magnets stick) or a board which allows mechanical attachment of other objects) and a graphic representation in which a color is dominant, wherein the graphic representation indicates a long time period (according to the teachings of the present invention), and the dominant color of the graphic representation indicates a subdivision of the long time period, and a graphic representation of an event. Thus on the substrate is attached an event and the time it is done, where the time is indicated using the time-telling language of the present invention.
A further preferred embodiment of the current invention uses the proposed language over a shorter time period and is useful as an activity timer.
The invention is herein described, by way of example only, with reference to the accompanying drawings, wherein:
