Abstract
Abstract A system is described for measuring the response of selected members of an audience, averaging the selected responses and presenting the average to the presenter as the presentation is being made to enable the presenter to adjust his presentation accordingly or respond to the audience response. The system includes a plurality of electrical response circuits having variable resistance manually operable devices individually distributable to the audience. Input resistors are included in each response circuit having resistance values at least 10 times greater than the maximum resistance of its variable resistance devices. The system includes switching means for placing selected response circuits in parallel with each other to a common line in series with an operational amplifier. The system includes a plurality of feedback resistors corresponding to the response circuits with the corresponding feedback resistors being placed in parallel with the amplifier to provide an output signal from the amplifier equal to the average of the selected response signals. It is important that the total feedback resistance placed in parallel with the operational amplifier is substantially equal to the total resistance of the selected response circuits. The output signal is transmitted to a readout device at the presenter''s console or lectern to provide the presenter with a continuous reading of the audience''s reaction to his presentation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
214 words
A participation presenter-audience response system for selectively measuring the response of an audience to a presentation given by a presenter and for displaying the measured response within the visual view of the presenter as the presentation is being Made to enable the presenter to adjust his presentation accordingly or respond to the response of the audience, said system comprising: a plurality of electrical response circuits; each of said response circuits having manually operable means individually distributable to separate members of the audience for producing an electrical response signal, the voltage magnitude of which is indicative of the relative response of the member of the presentation; control and processing means for selecting one or more of the electrical response circuits and for averaging the electrical response signals of the selected circuits and producing an output electrical signal having a voltage magnitude that is the average of the voltage magnitudes of the selected response signals; and a display means positionable in the visual view of the presenter and coupled to the control and processing means for receiving the electrical output signal and producing a visual representation depicting the average response of one or more members of the audience to the presentation as the presentation is being given to enable the presenter to adjust his presentation accordingly.
Claim 2
Dependent Claim
214 words
A participation presenter-audience response system for selectively measuring the response of an audience to a presentation given by a presenter and for displaying the measured response within the visual view of the presenter as the presentation is being Made to enable the presenter to adjust his presentation accordingly or respond to the response of the audience, said system comprising: a plurality of electrical response circuits; each of said response circuits having manually operable means individually distributable to separate members of the audience for producing an electrical response signal, the voltage magnitude of which is indicative of the relative response of the member of the presentation; control and processing means for selecting one or more of the electrical response circuits and for averaging the electrical response signals of the selected circuits and producing an output electrical signal having a voltage magnitude that is the average of the voltage magnitudes of the selected response signals; and a display means positionable in the visual view of the presenter and coupled to the control and processing means for receiving the electrical output signal and producing a visual representation depicting the average response of one or more members of the audience to the presentation as the presentation is being given to enable the presenter to adjust his presentation accordingly.
Claim 3
Dependent Claim
54 words
The response system as defined in claim 1 wherein the control and processing means includes switching means for coupling the selected response circuits in parallel so that the reciprocal of the total resistance of the selected response circuits is equal to the sum of the reciprocal of the resistance of each selected response circuits.
Claim 4
Dependent Claim
93 words
The audience response system as defined in claim 2 wherein the control and processing means includes (1) an amplified means for receiving the selected response signals and producing the output signal and (2) a plurality of feedback resistors corresponding to the response circuits; and wherein the switching means selectively couples the feedback resistors in parallel with the amplifying means so that the total resistance in parallel with the amplifying means equal the total resistance of the selected response circuits to produce an output signal that is the average of the selected response signals.
Claim 5
Dependent Claim
28 words
The audience response system as defined in claim 3 wherein each feedback resistor has a resistance value substantially equal to the resistance value of a corresponding response circuit.
Claim 6
Dependent Claim
54 words
The audience response system as defined in claim 1 wherein each response circuit includes a manually operable variable resistance device connected in series with an input reference resistor in which the resistance value of the input reference resistor is at least 10 times greater than the maximum resistance value of the variable resistance device.
Claim 7
Dependent Claim
39 words
The audience response system as defined in claim 1 wherein the display means includes a readout device mountable on a lectern positioned in front of the presenter for enabling the presenter to monitor the audience response to his presentation.
Claim 8
Dependent Claim
27 words
The audience response system as defined in claim 6 wherein the control and processing means is mounted in a control console that is separate from the lectern.
Claim 9
Dependent Claim
97 words
The audience response system as defined in claim 7 further comprising a dummy response circuit mounted in the control console having a manually operable variable resistance device for producing a dummy response signal and a selector switch mounted in the control console electrically between the control and processing means and the display means to enable an operator of the control console to terminate the output electrical signal and apply the dummy electrical signal to the display means to provide a visual representation to the presenter that is not an authentic response of any member of the audience.
