A dual-position switch (14) simulating a safety latch is again manipulated by the forefinger, this time to turn the television ON or OFF.An array of manually-actuable switches (151 - 160) is located on a side of the barrel of the handgun-shaped device. <IMAGE>

Description

ERGONOMETRIC REMOTE CONTROL DEVICE FIELD OF THE INVENTION This invention relates generally to remote control devices for electronic appliances such as televisions and, more specifically, to manually-manipulated remote control devices that are ergonometrically configured for (a) simplicity of operation, (b) logical and intuitive function, and (c) sensory feedback.

BACKGROUND OF THE INVENTION Modern electronic appliances, such as televisions and video tape recorders (VCR's), commonly incorporate low-cost microprocessor-based controls. The microprocessor control imparts a degree of "intelligence" to such electronic appliances, having the capability to read and write memory stored with parameters that are developed and used during the course of appliance operation.

Modern electronic appliances are often remotely controllable in their operation. Remote control of the appliance permits a user to conveniently control the appliance's operating condition frcm any position. The remote control device may be of various levels of sophistication in its electronic circuitry and nay also be controlled in the performance of its functions by a microprocessor executing a firmware control program.

Remote control devices have been constructed with many different types and numbers of electrical switches arrayed in commensurate patterns. Both the numbers and organization of the switches reflect the control function sophistication. The standard remote control device for common television is typically in the shape of a small parallelepiped body or elongate rectangular box.

It has approximately twenty to forty (20-40) push-button switches arrayed over one major surface or panel.

Certain remote control devices are of the "universal" type that functionally replace a number of dedicated remote control devices using preprogrammed infrared light remote control signals.

Of such "universal" remote control devices, the "Pre-programmed Four-In-One Universal Replacement Remote Control" available from Radio Shack Division of Tandy Corporation is typical. It permits the remote control of devices such as televisions, VCRs, CD and video disk players, stereo systems, and/or satellite systems that use infrared remote control. Similar reconfigurable remote control devices are taught in U.S. patents 4,825,200 for a "Reconfigurable Remote Control Transmitter"; 4,855,746 entitled "Multiple Device Remote Control Transmitter"; and 4,856,081 for a "Reconfigurable Remote Control Apparatus And Method Of Using Same." The contents of these patents are fully incorporated herein by reference.

This standard shape and switch layout of a television remote control device as mentioned above, permits manipulation of the device's functionality by the fingers of a single hand. However, the standard remote control device conforms poorly to both the shape and the dexterity of the human hand and fingers. Its box design is ergonomically deficient because it does not fit the hand well. The switch layout known in the art is ergonomically defective because the switches are generally too numerous, too small, or too closely spaced. The switches are often undesirably devoid of any sensory reference, including the shape or feel of the switch itself as well as nearby markers or contours, and/or devoid of any sensory feedback upon switch actuation. Further, the switches are not logically located to the extent that the switch most frequently used is the easiest to actuate by the operator.

Deficiencies in the ergonomic design of a conventionalsremote control device frequently require that even a regular user of the remote control device who is completely familiar with its-operation must visually search for, acquire, and identify the particular switches that are to be actuated. Namely, the fingertips often have to be visually positioned upon the desired switches or else the user may push switches incorrectly. In a darkened room, this can be very inconvenient and, at times, exasperating.

The remote control device is often difficult to both grasp and manipulate, and is frequently fumbled to a various extent during use. As a result of the deficient ergonomics of a typical boxshaped remote control device, either both hands and/or both eyes, as well as the fingers, must frequently be used for effective manipulation.

Manufacturers of television remote control devices apparently recognize that such devices are not intuitively obvious in their operation and that they are often difficult to manipulate for the results intended by the user. Accordingly, practitioners in the art have proposed some "helps" for incorporation in the control.

Frequently-used switches on the remote controller, such as the power ON/OFF and/or CHANNEL UP/CHANNEL DOWN and/or VOLUME UP/VOLtn4E DOWN switches on a television remote controller, are often enccded by shape, enlarged in size and/or positioned at a separation or in a distinctive pattern from other arrayed switches. Despite these modifications, there is little or no current industry standardization nor research based logic applied to the placement, relationship, shape or size of even the most common switches.

Because of the large number of switches, it is rare that the owner of a television has the exact placement of all the push button (or other) switches of his/her remote control device memorized so as to be capable of manipulating such switches without visual reference (such as in the dark). It is even rarer that a person can feel such confidence so as to pick up a television remote control device with which he or she is unfamiliar (such as a remote control device located in the home of a friend) and attempt to manipulate it in order to control a television without careful visual study of the switch labels and of the digital manipulations of the switches.

Users of remote control devices typically accept the awkwardness in their use as inherent. Compared to the bewildering complexities of the control panels of the electronic appliances themselves and the sophisticated functionality and control of appliances such as video cassette recorders (VCR's), a typical remote control device is comfortably benign. However, the ergonomics of a remote control device can be improved.

Existing remote control devices generally suffer from a number of particular disadvantages.

First, the box-shaped construction of the standard remote control device is difficult to both hold and manipulate with one hand, frequently requiring one hand to support the body of the device while the other hand presses its switches. If two hands are not used, then the remote control device is susceptible to being fumbled.

Second, the box-shaped construction of the standard remote control device does not present suitable tactile reference points permitting precise hand/brain localization and identification of the (typically many) switches. The planar surfaces of the parallelepiped body provide no distinct spatial reference to the hand nor to the fingers. Significant spatial tactile reference is provided only at the corners of the device. Insignificant tactile references are provided at other locations. The corners are in large part too distant from the typically small switches for effective tactile location or identification of switches solely by reference to the geometry of the box. Indeed, the elongate box shape of most remote control devices commonly makes it very difficult to properly spatially orient the remote control device during use while simultaneously feeling both a corner (fcr positional reference) and a switch (for actuation) with the fingers of a single hand.

Third, the switches of a box-shaped remote control device are necessarily small. Additionally, they are often tactually indistinguishable when located in a grid array upon a singlè tajor surface of the box. When the box-shaped device is held with one hand, the thumb is used to selectively press one or more small push button switches located at close spacing. The poor dexterity in the thumb compared, for example, with the index finger, frecuently results in actuation of the wrong push button switch.

Fourth, the box-shaped construction of a standard remote control device often requires the user to see the device to successfully manipulate it with the fingers. Looking at the device temporarily impairs the user's proper visual attention to the effects of his/her switch manipulations on the television or other controlled electronic appliance, diverts the user's attention from the television, and diminishes the enjoyment of television viewing.

Fifth, the box-shaped control does not have a handle. This contributes to ineffective user control or manipulation of the control features of the device. Any user attempt to manually grasp and pick up a remote control device with the hand may result in unwanted push-button switch operation, especially if the device is at a far reach.

Manual input devices that permit sophisticated control by hand and fingers are known in the art. A keyboard is one such device.

A keyboard is, however, an unsuitable model for a television remote control device. It requires "typing" skills to operate and is unsuitably- large for use in the television-viewing environment.

One class of devices that is highly ergonomically evolved for sophisticated control by the hands and fingers is firearms. The operational controls and the operative relationship of parts of common firearms, and particularly the semi-automatic action pistol, are extremely well-adapted for permitting the reliable user control of the firearm with minimal training and minimal chance of error.

Moreover, the way that pistols function, and are controlled to function, is almost universally recognized in modern American society. All but the youngest children will, by experience and familiarization, pick up a pistol or anything shaped as a pistol, by its grip and not by its barrel. Almost no one ever holds the grip of a pistol backward with the barrel pointing toward oneself.

Instead, a person picking up a pistol invariably recognizes that the operative muzzle end of the pistol must be pointed and correctly holds the pistol properly by its grip.

The pistol's trigger, its most important, controllable, functioning element, is located at an optimal location for easy repetitive manipulation by the index or trigger finger. The safety of an automatic pistol is generally located on the body of the pistol where it can be manipulated by either (a) the same index finger that is otherise used to squeeze the trigger, or (b) the thumb. This simple relationship is profound in its significance: the automatic pistol is not to be discharged simultaneously that its safety is being manipulated (in either sense) because this would represent an illogical, nondeterministic, sequence of events.

Even the hammer of a revolver or automatic pistol represents, in its various cocked and decocked positions, an ergonomically superior site for a control input, this time using the thumb of the hand that holds the revolver or pistol. Alternatively, the thumb may be used in still another position to actuate the slide release lever of an automatic pistol (or the release of a revolver). Both of these control sites may be easily, and unambiguously located by and reached with a user's thumb even while the user holds the pistol by its grip and rests his/her index finger upon the trigger.

When a second hand is called into play in the manipulation of a pistol or revolver, then this hand deals with control sites on the pistol and performs manipulations that are distinctly different and separate from those control sites and manipulations performed by the hand that grasps the pistol or revolver.

The human sense of vision is not ignored in the design of the automatic pistol. It is simply put to a better use than simply locating the control sites of the pistol. Indeed, the eyes are used to acquire the target at which the pistol is aimed.

The result of the evolved ergometric design of a pistol is a device that is quickly learned, seldom forgotten, and successfully manipulatable with a single hand by all but the clumsy or disabled.

Certain previous devices in the shape of pistols have peen used to directionally emit light under trigger control and to perform other simple functions, but without relationship to the problem of how one might best employ the superior ergonomics of a pistol to the design of a television remote control device. One example of such a device is shown in U.S. patent 4,171,toll for a "Light Gun With Photodetector And Counter." A toy gun emits light under trigger control and also collects in a parabolic deflector light that is reflected from a target. If sufficient reflected light is detected, an audible indication of a "hit" is made.

U.S. patent 4,147,355 for a "Target Shooting Apparatus" shows an operator-controlled simulated gun projecting a light beam toward a target each time a trigger is actuated.

U.S. patent 3,426,475 for a "Toy Gun Having Electromagnetic Radiation Means" shows a toy gun that emits electromagnetic waves suitable for television reception (not television control) under trigger control. A visual, and an audible, effect on the television's picture and sound are produced by the gun's emission.

These and other previous devices show that it is known to emit signals used for (remote) control from electronic devices in the shape of firearms, including pistols. These previous devices do not show the adaptation of the ergonomic principles of pistols to the relatively complex, multi-faceted, control tasks performed by a standard electronic appliance, and particularly a television, remote control device.

SUNMARY OF THE INVENTION This invention contemplates an ergonomically-designed remote control device in the shape of a handgun that is designed to be held by a human hand and manipulated by the fingers in order to control a remotely-located electronic appliance, and particularly a television, that is responsive to received signals for adjusting the parameters of its operation.

A plural-position switch is located in a trigger region of the simulated-handgun body member. This plural-position switch is manipulatable to each of several positions by a trigger finger, normally the forefinger of the human hand that normally grasps and holds the body member. The plural-position switch may be implemented as either (a) a number of closely-linearly-arrayed push button switches; (b) a single multi-function push button switch; (c) two trigger switches, one forward and one rearward, visually similar to the dual triggers of a derringer pistol and which may be actuated by movement in either the forward or rearward direction, or preferably, (d) a rocker switch having a neutral position and two opposite.rocked positions.This switch is associated with the most used functions of the remote control device, normally the CHANNEL UP/CHANNEL DONfflN functions. Because it is ergonomically correct, this most used switch is actuated in the easiest manner by the operator -- by means of the trigger finger.

A remote control transmitter affixed within the body is responsive to each of the several positions of the plural-position switch. In the preferred embodiment and by way of example, the transmitter is responsive to a first position of the pluralposition switch to emit a first signal that is detectable by a remotely-located electronic appliance in order to effect a CHANNEL UP function. Conversely, the transmitter is responsive to a second position of the switch to emit a second signal to effect a CHANNEL DOWN function.Particularly when the plural-position switch is, as is preferred, a rocker switch so that its first rocked position is disposed toward the barrel of the simulated handgun body member, and so that its second rocked position is disposed toward the butt of the simulated-handgun body member, then the CHANNEL UP-CHANNEL DOWN control is naturally, simply and easily accomplished.

Further in accordance with the present invention, the pistolshaped remote control device includes another second pluralposition switch. This plural position-switch is located in a hammer region of the simulated-handgun body member. It is manipulated to each of the plurality of positions by a thumb of the same human hand that holds the body member at its grip region. The second most used control function is thus located in the second easiest location for the operator to actuate.

Similarly to the alternative implementations of the first arrayed as (a) a VOLUME UP switch located closest to the top of the barrel of the simulated-handgun body member and at the tip of the "L", (b) a VOLUME DOWN switch located-closest to the butt of the grip of the simulated-handgun body member and at the corner of the "L", and (c) a MUTE switch located to the side of the other two switches, and at the tip of the leg of the "L". The actuations of these three switches by the thumb, as signaled to the soundemitting electronic appliance by the transmitter, are used to adjust the single parameter of sound output level.

Additionally, the pistol-shaped remote control device includes a dual-position switch that simulates a safety latch to the body member. This switch is manipulated in the manner of a pistol's safety latch to each of two positions by the forefinger of the human hand that holds the body member in its grip region. The transmitter is responsive to each of the two positions of the dualposition switch for momentarily emitting signals, that turn the appliance ON or OFF when detected by the remotely-located electronic appliance.

Further, an array of manually-actuable switches is located on a side of the barrel of the handgun-shaped body member. In this position each such switch is actuable by a forefinger of the same human hand that grasps the grip of the body member. The transmitter again functions in response to the forefinger's actuation of one of the array of manually-actuable switches to emit a corresponding one of a number of control signals. The signals are detectable by the remotely-located electronic appliance to adjust several operational parameters.

When the remotely-controlled appliance is a television, the arrayed switches typically permit channel selection, previous channel recall, cable/broadcast input signal selection, and various other inputs as are common for the remote control of televisions.

Still further in accordance with this invention is an indicator light located at the front sight position of the handgunshaped body member. The indicator light is responsive to the transmitter for illuminating over the duration of any signal emission by the transmitter.

The collective result of the various switches and switch placements upon the handgun-shaped body member is to realize an ergonomically-superior remote control device that is both conceptually and physically very easy to hold, learn and use. Most people who have used the device but a few times never again have to visually reference the locations of at least the more common control switches for control of the CHANNEL UP/CHANNEL DOWN and the VOLUME UP/VOLUME DOWN functions. This invention is the result of ergonomic research whereby the most used switches are actuated by the most easily and naturally manipulable digits of the operator's hand, and other switches are arranged in a hierarchical order based on frequency of use coupled with ease and naturalness of actuations.

BRIEF DESCRIPTION OF THE DRAWING The objects advantages and features of the inventions will be more readily perceived from the following detailed description, when read in conjunction with the accompanying drawing, in which: Fig. 1 is a side view showing a preferred embodiment of pistol-shaped remote control device, particularly for a television, in accordance with this invention; Fig. 2 is a partial side view of a detail of an alternative configuration of a plural-position switch, located at the hammer region of the device in accordance with the invention; Fig. 3 is a partial side view of a detail of an alternative configuration of a plural-position switch located at the trigger region of the remote control device of this invention; and Fig. 4 is a schematic diagram of a control circuit suitable for use in the remote control device of this invention; DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawing, and more particularly to Fig. 1 thereof, there is shown pistol-shaped remote control device 1 and electronic appliance 2, normally a television receiver, which is shown in phantom lines because it is not a part of this invention.

The link between remote control device 1 and television receiver 2, which are not illustrated to scale, is symbolically indicated by arrow 3. Whether the link uses waves (e.g., ultrasound, infrared waves) or any other means is immaterial to this invention. The remote control device in accordance with this invention could even use a physical cable or a focused electromagnetic beam, such as a laser, as its communication link to the controlled device. It will be appreciated that the remote control may be adapted to control the television receiver through link 3 by means of a narrow focused beam of light, whether visible or infrared, suitable for designating individual pixels in a television screen display, as well as effecting control of television receiver channel, sound and the like.

Remote control device 1 includes a generally handgun-, or pistol-shaped housing member 11 on which are mounted a number of electrical switches. It is within the contemplation of this invention that various pistol, machine gun, or rifle styles may be used for housing member 11 without deviating from the spirit of the invention. The material used to construct the housing member is generally plastic. However, other suitable material can be used to construct the housing member, including but not limited to various metals, plastics, or even natural materials such as wood. The housing member can be variously colored, including but not limited to black, green camouflage, or "Desert Storm" camouflage.However, if the housing member is colored any metallic or other color such as might tend to deceive a person perceiving the housing member at a distance and/or under poor lighting conditions into believing that is was real weapon, then the laws of various states require that the muzzle region of housing member 11 should be brightly colored, such as in safety orange or yellow. The housing member and/or any of its switches such as will be discussed, can particularly be colored in "neon" fluorescent colors such as bright orange and chartreuse. When the plastic material of the housing is appropriately impregnated with florescent agents (such as are common in the plastic fabrication arts), the remote control device will glow in the dark, facilitating both its identification and use.

In accordance with this invention, several external switches and interior electronic elements of remote controller 1 have the preferred configurations, and placements, that are generally illustrated in Figs. 1-3. Control circuit 20 and energy source 21, normally a battery, are preferably located within the handle, or grip, region 110 of housing member 11. Integrated signal emitter and transmitting lens 103, normally an encapsulated photo or laser diode and accompanying lens, is preferably located at distal end or muzzle 104 of barrel region 111 of the housing member. Activity light 24, normally one or more integrally-packaged light emitting diodes (LEDs), is located generally at the position of a front sight on the handgun-shaped housing member.

A first plural-position switch 12 is located generally at a trigger region 113 of housing member 11. This switch is manipulatable to each of several positions by a forefinger (not shown) of the human hand as it grasps the housing member in its grip region. Switch 12 is preferably implemented as rocker switch 121 shown in Fig. 1. If not subjected to force, rocker switch 121 assumes its illustrated neutral position. Under force of 'the forefinger the rocker switch will assume two additional opposite rocked positions.

Plural-position switch 12 nay alternatively be implemented as the two, forward and rearward, trigger switches 122, 123 shown in Fig. 3. These switches are similar in appearance, and in operation, to the dual triggers of a derringer pistol. Finally, plural-position switch 12 nay be implemented as a number of closely-linearly-arrayed push button switches, in the manner of the switches 13 (to be explained below).

Control circuit 20 is responsive to each of the several positions of plural-position switch 12 to transmit a first signal in response to a first finger-actuated position of the switch, and a second signal in response to a second position of the switch.

These signals are detectable by a remotely-located electronic appliance, normally television receiver 2, in order to respectively adjust a first operational parameter in a first UP or in a second DOWN direction.

Research has shown that the switch or switches having the CHANNEL UP and CHANNEL DOWN functions are most frequently actuated when using a TV remote control. This invention exploits that knowledge by locating the channel changing switch ergonomically, that is, at the place where -t is most easily and naturally actuated by the operator. For a pistol shaped device, that location is the trigger switch area, designed to be operated by the operator's trigger finger, a very natural motion.

When plural-position switch 12 is implemented as the rocker switch 121 shown in Fig. 1, the - -Sl rocked position is preferably disposed toward barrel region 111 of the housing, and the second rocked position is preferably disposed oppositely, toward butt region 114 of the housing. By this switch placement and orientation, the CHANNEL UP-CHUNNEL DOWN channel control of television receiver 2 is most naturally, and simply, accomplished.

Another, second, plural-position switch 13 is located in a hammer region 115 of housing ember 11. This plural-posXition switch 13 is manipulatable to each of the plurality of positions by a thumb of the operator's hand (-.ot shown) which holds body member 11 at its grip region 110.

Similarly to the plural-position switch discussed above, switch 13 may be implemented in several alternative configurations.

This plural-position switch may be implemented as a rocker switch 134 (shown in Fig. 2), which is equivalent in action and orientation to rocker switch 121. It is, however, preferred that switch 13 should be implemented as an array, normally three in number, of small push button switches 131-133. The arrayed push button switches are preferably located in the shape of an '1L1'.

Just as with switch 12 located in the trigger region, control circuit 20 is responsive to each of the several positions of second switch 13 located in hammer region 115 to transmit signals in response to thumb-actuated positions of the second switch. These further signals are detectable by the remotely-located electronic appliance to adjust one or more of its operational parameters, and preferably just one such parameter.

Research shows that the second most used remote TV control switch is that which controls volume. After the trigger finger, the second easiest and most natural control motion is with the thumb of a pistol holding hand. Thus, the volume control switch is placed for ease and natural actuation by the operator's thumb. In addition to a TV, any audio appliance has a volume variable function to which the principles of this invention are applicable.

Preferably push button switch 131 located closest to the top cf the barrel region Ill of the housing member, and at the tip cf the "L", serves as a VOLUME UP switch. Push button switch 132 located closest to the butt region 114 of the housing member, and t the corner of the "L", serves as a VOLUME DOWN switch. Finally, switch 133, located to the side of switches 131, 132, and at the tip of the leg of the "L", preferably serves as a ìCUTE switch. Thumb actuations of these three switches, one switch at a time, as is signaled to the sound emitting electronic appliance by the transmitter within the control circuit 20, are used bp the appliance to adjust the single parameter of its sound output level.

A dual-position switch 14 simulates a - safety latch to simulated-handgun housing member 11. This dual-position switch is manipulatable in the manner of the safety latch of an automatic pistol to each of two positions by the forefinger (not shown) of the operator's hand that holds the remote controller. Switch 14 is normally a slide switch. The transmitter within the control circuit 20 is responsive to the two positions of switch 14 for emitting momentary signals, that when detected by the remotelylocated electronic appliance, turn the appliance either ON or OFF.

Ergonomically, this is a switch position that is easily accessible and the slide-type switch is easily actuated. The ON/OFF functions are normally the third most used on a remote controller.

Note that switch 14 is described as "dual-position" whereas switches 12 and 13 are described as "plural-position". The distinction is rooted not so much in the physical type of the switch, of which many different 2-, 3- or more-position switches will suffice in each application, as what control signal(s) each switch, and the control circuit 20 (Fig. ,2) should produce in combination. The several positions that each switch 12-14 will physically assume, whether or not each switch is spring-loaded and will maintain the assumed position once the force of the fingers is released, and the numbers and durations of the control signals that will be emitted in response to switch actuation and repetitive actuation, is a matter of choice.

It is preferred that the plural-position switches 12 and 13 should be spring-loaded, and should cause the continuous emission of a control signal upon which the electronic appliance will respectively act for the duration of switch actuation.

However, dual-position switch 14 is normally not springloaded, and will maintain either of two stable positions once assumed. Upon initial assumption of each position only one control signal is emitted for a predetermined period, normally in order to direct the electronic appliance to power ON or power OFF. If the appliance misses the controlled signal then switch l must be recycled. Note that this operation is slightly different than the standard two, ON and OFF, push button switches typically found on previous remote control devices.

An array 15 of manually-actuable switches 151-165 is located on a side of the barrel region 111 of housing member 11 in a position where each such switch is actuable by a forefinger (not shown) of the operator's same hand that grasps grip region 110 of the body member. The transmitter within control circuit 20 again functions in response to the forefinger's actuation of one of the array of manually-actuable switches to emit a corresponding signal that is detectable by the remotely-located electronic appliance, in order to adjust a corresponding one of its several operational parameters. The arrayed switches 151-160 typically signal the digits 0-9 to permit channel selection.Switch 161 is actuated to signal previous channel recall, switch 162 to cause the display of the present channel number, and switches 163-165 are to select between various combinations of signal sources to the television receiver. Still other switches, and switch functions, as are commonly used for the remote control of televisions and other electronic appliances are clearly adaptable to housing member 11, and are compatible with the principles and spirit of this invention.

The collective result of the various switches, and switch placements, upon a handgun-shaped body member is an ergonomically- superior remote control device that is both conceptually and physically very easy to hold, learn and use. Most people who have used the device but a few times never again have to visually reference the locations of at least the more common control switches for control of the CHANNEL UP/DOWN and the VOLUTE uP/rO'.S functions.

Variations in switch type, configuration and/or placement are each possible. It is possible to have and use a moveable slide and/or a moveable hammer to perform an electrical switching function. A slide locking lever (not shcwn) may be used as an electrical switch. Push button switches, or arrayed push button switches may be placed on both sides of the simulated gun. The push button switches may be recessed below the surface of housing member 11 in order so that they should be not actuated by accident.

The tops of the switches may be fluorescent, or may contain LEDs that light when the switch, or a particular switch position, is actuated. The tops of the switches may vary in texture, size and particularly, in shape.

As is best seen by the indicia adjacent the keys 151-165 on the housing member 11, each switch is generally associated with a separate one" of the control functions that is common to the different controlled devices. However, the functions of the individual switches are a matter of choice. An arrayed plurality of switches may include one or more switches that, while being used to provide a control input to a particular controlled device (e.g., a television), may also be used to control a different device (e.g., a cable box, VCR, CD player, telephones in various configurations, among others).

Although this invention has been explained in the context of a television remote control device, it is clear that a variety of electronic apparatus can be controlled with the same remote controller either separately or simultaneously.

It will be appreciated that the arrangement of switches for operation is a matter of ergonomic design. The word "ergonomic" is used herein in its general sense to mean not only the design of human work environment, but also the broader, general, human environment in which the remote controller in accordance with this invention is commonly used. Thus, only a rudimentary illustration, and description, of the invention is made. Details of the implementation, such as a possible mechanical interlock between one or more of the switches as are shown is well within the capabilities of those skilled in the electromechanical design arts.

It will also be appreciated that pistol-shaped housing member 11 in Fig. 1 provides ergonometric advantages primarily because of the availability of switches on opposing sides of the housing.

Opposing switch groups such as switches 12 and groups 13 and 15 offer ease of access to the digits when grasped in the human hand that are not normally available on remote control devices known in the art. Although the pistol-shape is the preferred ergonometric shape, other similar housing shapes offering the same opposing switch locations may also be ergonometrically advantageous in accordance with this invention.

The manner of operationally using gun shaped remote controller 1 to control an electronic apparatus, and particularly television receiver 2, is similar to that for remote controllers in widespread present use; Namely, one first holds the controller in the hand, normally the right hand. The index finger is then first used to press the dual-position switch 14 serving as an ON/OFF switch, and then to assume a position on plural-position "trigger" switch 12.

Any pressed key will cause function light 104 located at the sight on the end of the barrel to briefly illuminate.

To change the channel in a ascending fashion, the user simply squeezes the upper-half of rocker switch 121, toggling the switch to its first rocked position. To change the channel in a descending fashion, the user simply squeezes the lower-half of rocker switch 121. Dual-trigger switches 122, 123 function commensurately.

To make a specific channel selection, the user reaches to the side of barrel region 111 of the housing with the index finger and presses the appropriate key sequence. For example, to select channel 10, the user presses push button switch 152 ("1") and then push button switch 151 ("0"). To recall a channel, the user simply presses recall push button switch 161 with the right index finger All these functions can be accomplished with the pstol-shaped controller gripped in normal fashion.

To change the volume in an ascending fashion, the user simply presses VOLUME UP push button switch 131 with the thumb. To change the volume in a descending fashion, the user presses VOLUME DOWN push button switch 132. To mute the volume, the user presses MUTE push button switch 133.

To display any current status, the user can press display push button switch 162 with the right index finger.

Still other control functions inputted in the switches of the preferred embodiment of remote controller 1 shown in Fig. 1, and other control functions that may augment these control functions, are realized by equivalent movements of the hand and fingers. Most control movements are both intuitively obvious and physically easy to make.

Remote controller 1 comprises, as an integral component, control circuit 20 for controlling its operations, and for commanding remotely-located television receiver 2. A schematic block diagram of a typical such control circuit 20 is shown in Fig.

Control circuit 20 is based on microprocessor 35. The microprocessor includes a central processing unit (CPU) 22; random access memory (RAM) 23 that is used, for example, by the CPU during its data processing operations; read only memory (ROM) 24 for storing predetermined remote control codes for controlling respective operations of television receiver 2; nonvolatile memory 25 which, for example, is of the metal-nitride-oxide semiconductor (MNOS) type, and is hereinafter further described in detail; input/output ports 26, 27, 28 and 29; and connecting bus 30.

Control circuit 20 further includes photo-electric, or light, transmitter and encoder 31 that is adapted to transmit an infrared or other control signal SR to remotely controlled appliance 2.

Under command of CPU 22, photo-electric transmitter and encoder 31 receives respective remote control code RC to modulate the emitted signal. Transmitter 31 is particularly intended for use with a particular, compatible television receiver 2. Both remote controller 1 and television receiver 2 employ a particular set of emote control codes for controlling corresponding operations of the television.

Remote controller 1 and its transmitter 2 may be of the universal programmable type capable of learning a distinct remote control code that is, subsequent to the learning, to be transmitted upon actuation of each of its several push button switches. Such a programmable remote control transmitter is, for example, taught within U.S. patent 4,769,643 for a "Transmitter Driver For Programmable Remote Control Transmitter," the contents of which are entirely incorporated herein by reference. Meanwhile, and potentially simultaneously as remote controller 1 learns an individualized repertoire of remote control codes, the television learns the identical codes.Such learning, implemented by control circuit 20, may occur in accordance with U.S. patent 4,807,052 for a "Remotely Controllable Electronic Apparatus," the contents of which are entirely incorporated herein by reference. Each serialized television and its remote control transmitter may be characterized with an individual repertory of control codes, and linked thereby at a time that is characteristically shortly before packaging and shipping. This can occur if necessary data is in the possession of the manufacturer to permit such a particular television, or a particular remote controller, to be created.

Push button switches 151-155 mounted on remote controller 1 and electrically connected to control circuit 20 are selectively manually actuable by a user. When one of these switches is closed or turned "ON", corresponding key-in data is supplied through input port 28 and bus 30 to CPU 22. CPU 22 responds thereto by providing a corresponding control signal for control of the respective function or operation. For example, switch 165 may be used for controlling that "CABLE" should be selected as an input signal source for the remotel-controlled appliance, or television receiver. More specifically, in response to closing of switch 165, a control signal is supplied from CPU 22 through bus 30 and port 26 to photo-electric transmitter and encoder circuit 31 which is operative to send an infrared light signal causing television receiver 2 to gate the television signal appearing at "CABLE" terminals (not shown) to ts tuner (not shown).

As stated previously, first multi-position switch 12 is preferably used for changing the TV channel. More specifically, each time switch 12 is closed in one sense, CPU 22 receives an up signal CHup through bus 30 and port 29. An analog to this signal is broadcast by the photo-electric transmitter and decoder so that the channel to which the television receiver is tuned is incrementally changed to the next higher numbered channel. Similarly, each time switch 12 is actuated in its other sense, CPU 22 receives a down signal CHdfl through bus 30 and port 29. Microcomputer 35 then causes encoder 31 to transmit an infrared signal that will cause the television receiver to incrementally change the channel to which it is tuned to the next lower numbered channel.

Again reiterating, second plural-position switch 13 is commonly used for controlling the volume of the television receiver sound. More specifically, when switch 13 is closed in a first sense, CPU 22 receives an up signal Vup through bus 30 and port 29.

Responsive to the receipt of this signal, CPU 22 causes transmitter 31 to send a signal which, as received by the television, will cause a volume control circuit in the television to increase the sound volume. On the other hand, closing of switch 13 in an alternate sense causes CPU 22 to receiver a down signal Vdn through bus 30 and port 29. The same volume control circuit will decrease the volume of the sound emanating from the television receiver.

MUTE switch 133 may be considered to be part of multi-position volume control switch 13 (as is illustrated in Fig. 2), or its physical structure and its function may be relatively more separated, -as is illustrated in Fig. 1.

Control circuit 20 is further shown to include light-emitting diodes 34 connected through input/output port 27 and bus 30 with CPU 22. LEDs 34 may be of the same or different colors, (e.g., yellow and green). They may be individually or ccllectively selectively supplied with energizing current from CPU 22 for indicating when an operation or other activity is started, and when such an operation is terminated.

The details of the integrated circuitry for generating the coded infrared or other remote control signals, the battery power source and the infrared or other transmitter, all situated in housing member 10 of remote controller 1, are not shown in xFig. 2 for the purpose of clarity.

Although the description above contains many specifics, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Additional Indicators both visual and audible, and even displays, may be placed on remote control device 1. For example, a small display, typically an LED display, may show, under microprocessor control, the number of the channel that is currently selected. In this manner, a current channel number by be known even if it is not currently displayed upon a television~screen, or even if it is incapable of being so displayed. Audible indicators are particularly useful for the blind or the elderly.Although common knowledge is that remote controllers for TV's should not emit sounds because it could interfere with or distract the viewer's attention, this invention is in part and preferably, for a noveLty device with valuable and practical functions. As such, audible. indicators can not only be fun, but have utility, as mentioned above. Of course, the controller of this invention need not be a novelty item.

The remote controller in the general shape of a handgun may be configured for, and used with, either the right of left hand.

However, any easily grasped, ergonomically positive shape is contemplated by this invention. The light indicator shown may be placed in a different location on the simulated handgun. The operative or indication buttons or switches may be clear or translucent and be illuminated from a light inside the body remover.

A light may be affixed to the remote controller to illuminate the switches or other objects. The operative buttons and switches may have any desired or practical shape.

The remote controller of this Invention is compatible with all types of reconfigurable technology. It may produce progra=mable flashes or responses which appear on the television screen. t may produce a focused beam to write upon the television image. t may, either independently of or incident to its transmissions (simulating firing), produce a noise, a flash of light, and/or a directed beam of light, including laser light, cr display mechanical motion.

Accordingly, in light of these possible modifications, this invention should be perceived to be embodied in a very simple, relatively easy to operate, remote controller incorporating many of the ergonomic principles of firearms, and particularly handguns, in order to permit sophisticated user control of a number of remotelysituated devices with minimal potential for error.

In accordance with these and other obvious adaptations and alterations to this invention, the scope of the invention should be considered to be defined by the following claims only and not solely by that preferred embodiment within which the invention has been taught.
