     SUMMARY OF THE INVENTION 
     The present invention, at least from one viewpoint, is an electronic device, which may take many forms as herein disclosed, but all including a combination of a electronic visual display in or on a housing, electronic circuitry in the housing, and including at least one human user depressible surface with associated analog pressure-sensitive element for output of a signal of variable value utilized by the circuitry to control or manipulate a function(s) of the device. The at least one analog pressure-sensitive element receives pressure applied by a user&#39;s finger (the word finger or fingers or digit can be herein used to include the thumb) to the depressible surface, varied pressure applied by the user determines varied value of the signal, and this allows the user to select rates of change, the rate of change in some way being displayed on the display to allow the user to choose more or less pressure, or to terminate pressure on the finger depressible surface. The resultant control manipulation from the analog variable value is in some manner indicated or made visually detectable as feedback 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. Some examples of functions which can be manipulated, controlled or changed, and at variable rates dependant upon user applied pressure, include menus or lists displayed on telephones, television program menus and the like, numeric settings such as related to time, temperature or number of units, such as number of copies to be made by a photocopy machine for example. Some additional examples of electronic devices described in accordance with the invention include desktop displays, hand-held game systems, personal digital assistants (PDA), electronic books, wireless web browsers, time display clocks/watches, cooking ovens, pagers, remote controller such as used with TVs stereos, etc., and coffee makers all with displays. The displays can be CRT, non-CRT, LCD, LED or any other suitable type and in many applications are seven-element numeric displays such as are commonly used to display number of units or time. 
     An object of the present invention is to provide an electronic device including a combination of an electronic visual display in or on a housing, electronic circuitry in the housing, and at least one analog sensor comprising a finger or thumb depressible surface with associated analog pressure-sensitive element for output of a signal of variable value utilized by the circuitry to manipulate one or more functions of the electronic device at varied rates, the manipulation in some manner indicated on the display at least at the time the user is pressing the depressible surface, thereby the human user is provided data allowing the intelligent increase, decrease or termination of the finger pressure to effect a rate of change.

     With reference now to the drawings for a more detailed description. 
     FIGS. 3-5 show various diagrams of general image displays that may be utilized with a variety of consumer electronic devices, such as a remote controller having a feedback screen, 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&#39;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&#39;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&#39;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 a hand holdable remote controller  6  in accordance with the present invention. In general a hand holdable remote controller is a device that is utilized to control a local parent device from a distance that is within the operable signal range of the remote controller, such as for example, a TV, radio, VCR, DVD, game console, garage door or the like. Shown is a housing  11  and a display  22  mounted within the housing  11 . At the central left of the housing is shown a 4-way analog rocker  18 . Shown at the mid-center of the housing is a 2-way analog rocker  16 , which can serve as an X-axis, horizontal control or scroller. Shown at the left side of the display on the housing is a 2-way analog rocker  14 , which can serve as a Y-axis, vertical control or scroller. Also shown, at the right adjacent the 4-way rocker are single buttons  19  and  20 . 
     A mix of analog sensors and simple switches can be applied as desired in any of the illustrated embodiments, hybrids, combinations or modifications of the embodiments shown herein. 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&#39;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 H invention should be defined by the broadest possible interpretation of the claims.
