Figs. 3-5 show various diagrams of general image displays that may be utilized with a variety of consumer electronic devices, such as an electronic book, and having a housing 11, a display 22 associated with housing 11, i.e. mounted on or in the housing 11, and at least one analog sensor 26 having a depressible surface area associated with the display. Analog sensors 26 can be ganged in 2-way and 4-way units such as rockers 14, 16 and 18, or can be in single button or surface form such as shown at 19 in some of the drawings. The analog sensor 26 in a preferred structure has a pressure-sensitive variable-conductance material for providing a variable signal varying with differing amounts of user finger applied pressure, however, the associated circuitry can be structured to additionally read a rapid press and release on the sensor as a momentary-On used to supply a single increment signal, e.g., single step numeric increase/decrease or scroll up/down. As the user's finger depresses the sensor material, its conductivity is read by associated circuitry, such as a microcontroller, reading the time of charge or discharge of a capacitor as determined by the conductivity of the analog sensor material. The devices that may be utilized with the present invention already have internal microcontrollers or even more complex circuitry, and one of average skill in the art can readily apply the analog buttons/sensors/analog rockers/analog membrane sensors to the indicated art with an understanding of this disclosure . Fig. 1 shows an exploded view of a 2-way analog rocker 14 or 16 as may be employed in embodiments of the invention as an analog sensor 26. Shown is a circuit board 40 with exposed interdigitated circuit traces 44 as a common, 42, 46 as outs or switch legs; two "pills" or disks of pressure- sensitive variable-conductance material 38; two rubber-dome caps 36 positioned beneath a 2-way rocker member 30. The 2-^' way rocker member 30 has a first depressible surface 32 and a second depressible surface 34. Each finger depressible surface 32, 34 for functioning by depression with the shown respective dome-caps 36, pills 38 and the circuit traces 42, 44, 46. It does not require a rocker to electrically achieve that which is accomplished with a 2-way or 4-way, 14, 16, 18 rocker, as two separate or four separate depressible buttons or surfaces (see Fig. 2) can be used although I prefer the rocker format for ease of locating desired direction oriented depressible surfaces simply by feel without having to look.

Fig. 2 shows an exploded view of a 4-way analog rocker 18 as may be employed in the embodiments of the current invention. Shown is a circuit board 40 with exposed circuit traces indicated at 62 for four sensors 26. Also shown are four pressure-sensitive variable-conductance pills or elements 38; a 4-way rubber-dome cap unit 56 with each of the 4 dome caps 60 support by base 58 over a "pill" or disk of pressure-sensitive variable-conductance material 38; and a 4-way rocker member having a first surface 48, a second surface 50, and third surface 52, and a fourth depressible surface 54. Each surface for functioning by depression with the shown respective dome-caps 60, pills 38 and circuitry 62 of the board 40. This disclosure discloses that which can be viewed from numerous points, but clearly herein described are improved methods, structures, and also methods of manufacturing in accordance with the present invention. Figs. 3-5 show block diagrams in accordance with the invention. Illustrated is a housing 11 containing two sensors 26, one sensor 26 having depressible surface 80 and the other sensor 26 having depressible surface 82. The sensors 26 are connected to circuitry 53 connected to a display 22. Also illustrated is a box representing a human user 72 with the user's eye 74 receiving visual feedback from display 22. The visual feedback received by the eye 74 at least in part influences the depressive pressure exerted by the user's finger 76 against sensor 26 which in turn is read by circuitry 53 which controls the visual feedback displayed on display 22, thus a closed loop feedback system is established in which the user 72 receives immediate feedback concerning the control of the electronic device according to the invention. The state of circuitry 53, as controlled by the user, can control other functions 78 of the electronic device.

Fig. 3 shows display 22 as a general image display. The general image display 22 includes an upper area and a lower area, thus a user may scroll data at varying rates from the lower area to the upper area by pressing surface 80, and from the upper area to the lower area by pressing surface 82.

Fig. 4 shows display 22 having two seven segment numeric displays 28, thus the user may select numbers at a variable rate by varying depression on sensors 26. For example, such selection may be for number of copies to be made by a photocopy machine, temperature setting of a thermostat, channel number on a television and the like. Depression of surface 80 is arranged in this example to cause a variable rate of ascending numbers according to the level of depressive pressure applied to surface 80. Depression of surface 82 is arranged in this example to cause a variable rate of descending numbers according to the level of depressive pressure applied to surface 82.

Fig. 5 shows display 22 having three seven segment numeric displays 28 as are commonly used in time displays. Thus the user may select at a variable rate, numbers representing timing, by varying depression on sensors 26. In Fig. 5, depression of surface 80 is arranged in this example to cause a variable rate of ascending numbers representing time according to the level of depressive pressure applied to surface 80, and depression of surface 82 is arranged in this example to cause a variable rate of descending numbers according to the level of depressive pressure applied to surface 82, or surfaces 80 and 82 can be arranged to control hours and minutes individually. Clearly a clock can be greatly advantaged by ascending and descending sensors 26 for both hours and minutes adjustments.

Fig. 6 shows an electronic book 4 or the like and modified in accordance with the present invention. U.S. Class 434 contains prior art patents describing electronic books for those wishing more information thereon. Shown in Fig. 6 is a housing 11 and a display 22 mounted within the housing 11. At the lower left corner of the housing is shown a 4-way analog Rocker 18. Shown at the left center of the housing is a 2-way analog rocker 14, which can serve as an Y-axis or vertical control or scroller. Although not shown, a 2-way X-axis or horizontal analog rocker can be mounted any place on the housing. Also shown in broken lines is a 2-way analog rocker 14 on the back side of the housing 11 which may be located anywhere on the back side of the housing. The analog rockers can be used for variable control of imagery or other functions. Also shown are two analog buttons 19.

The present electronic devices utilize analog sensors and circuitry for reading at least three readable states, analog values or conductance levels of each of the analog sensors; the states, values, levels or the like may be or can be varied voltages or currents (example only) , and are varied dependant upon depressive pressure applied to a finger depressible button associated with each analog sensor. Button may be ^■ herein treated as the finger depressible area of a rocker member such as a 2-way or 4-way or the like. The associated circuitry is structured to read an immediate, instant or current state or value of the analog sensors and to communicate representative control signals. The at least three states of the active element (analog sensor) can represent at least: 1) no pressure, 2) low pressure, and 3) high pressure applied to the depressible surface by the human user's finger or thumb (digit), the 3 level equating to rates of change. The analog sensor and circuitry arrangement can be employed in a manner wherein not just three but many states are read, thus ensuring high resolution reading of a variably changing depressive button pressure input. Preferably, many different user determinable rates (many different states rate by the circuitry) are provided between low and high pressure on the associated button so that the user is provided, for example, very slow, slow, medium, fast and very fast change rates. With the analog sensors, the user is provided variable change rate control dependant upon the degree of depressive pressure he or she applies to the button associated with the analog sensor (s) which is indicated or made visually detectable on the display at least at the time the analog sensor is being depressed, and this to allow the intelligent application of finger pressure by the user to the analog sensor. Based on the information shown on the associated display, the user can choose to increase, decrease or terminate finger pressure on the analog sensor. Such an arrangement provides the user vastly improved control by allowing the user to apply low pressure to have a slow rate of change, or to apply high pressure to initiate very rapid change, and then to reduce the applied pressure to the button to reduce the rate of change in order to stop easily and precisely on a desired target or within a desired area, such precise control is clearly advantageous and desirable.

The invention can be viewed or defined in numerous ways including structure and methods as those skilled in the art will realize upon a reading of this disclosure presented to exemplify rather than limit the invention. Thus, the invention should be defined by the broadest possible interpretation of the claims.
