Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates generally to audience participation and identification devices, and more particularly to a system, article, and method for providing one or more positional spotlights to identify and sequence audience participation during question and answer sessions. 
     2. Description of the Related Art 
     It is common practice to follow speaking presentations to medium to large audiences with a period of time reserved for a question and answer session. Quite often, during the presentation itself, the house lights are dimmed so that attention is focused on the speaker or presentation materials. During the question and answer session however, the house lights must be turned on so that the speaker or facilitator is able to identify and select audience members to ask their questions. Audience members who are not initially selected must either keep their hands in the air, or risk losing priority in the arbitrary sequence of questions asked. If a wired or wireless microphone is available, a facilitator must physically hand-deliver the wireless microphone to the audience member&#39;s general location. Otherwise, if a microphone is not available, the speaker must repeat the question asked for the benefit of other audience members who may not have heard the current question. In addition, audience members who interrupt or proceed with a question without raising their hands occasionally disrupt the sequential flow of questions.

     DETAILED DESCRIPTION 
     Embodiments of the invention provide a method, article and system for providing one or more positional spotlights to identify and sequence audience participation during question and answer sessions. 
     Embodiments of the system of the invention provide one or more narrow-beam focused spotlights that may be repositioned in response to computer control signals to indicate a sequence of audience members who wish to participate in question and answer sessions at the end of presentations. The computer signals are generated utilizing trigonometric algorithms and relationships to calculate positional offsets. The positional offsets are applied to the current position of the spotlight(s), beginning with a known starting default position of the spotlight(s), using a vertical angle adjustment and a horizontal angle adjustment to move and position the one or more spotlights to focus on the next audience participant in the sequence. Inputs to the trigonometric algorithm are drawn from seat location field values stored in a small-footprint database in the application system. 
     Audience members utilize embodiments of the invention to indicate their desire to ask a question by pressing an indicator control at their seat location. The sequence of audience member participation in the question and answer session is determined by the chronological order in which the seat-side indicators have been pressed. The audience members have access to a wired or wireless microphone, positioned near their seat location, which is activated when an audience member&#39;s turn to ask a question occurs. In addition, all other audience seat-side microphones are deactivated, which reduces the possibility of the designated audience member being interrupted. The presenter or lecturer at the podium may manage the queue of audience members waiting to ask questions through the use of a laptop, workstation, or some other user interface device to see how many (if any) audience members are waiting to ask questions. The ability of the presenter or lecturer to identifying the number and proper order of questions to address, aids in the efficient management and pace of answering audience member questions. 
     In embodiments of the invention, the one or more narrow-beam spotlights may be fixed or mobile and portable, and may dynamically determine where they are in the room in relation to the seating or audience member locations. The narrow-beam spotlights may also be integrated with cameras, which are also pointing at the audience member asking the question. The cameras feed video of the person asking the question to a presentation screen. In an alternative embodiment, the spotlights may work in tandem with separately located and mounted video cameras, which are repositioned using the same trigonometric algorithms and relationships that are used to aim the spotlights. In a further embodiment, the auditorium lights may not be dimmed, and the spotlight may not be used, instead a series of user interfaces at the audience member seats indicates which audience member in the sequence has their turn to speak, while all other audience microphones are deactivated. 
       FIG. 1  is a top down view of an auditorium  100  for illustrating the positional identification of audience members according to embodiments of the invention. The auditorium  100  is set up for a presentation with a podium, stage, or dais  102  to accommodate one or more speakers or presenters, and a series of rows of seats  104 . A control panel of indicators  118  is available at each seat  104 , and includes a set of buttons that may be pressed by audience members wishing to ask or retract a question. The control panel of indicators  118  at each seat contains a wireless microphone connected to an audio amplification system  116  in the auditorium. When an audience member indicates a desire to ask a question, a transaction is transmitted to a computer system  112  which records the seat location and sequential order of receiving the request in a database table  114 . 
     The database table (a small portion of which is illustrated in Table 1 records the positions of each of the seats  104  based on a three dimensional coordinate system with an X and Y axis in a horizontal plane that is parallel to the floor of the auditorium  100 , and a Z axis (see  FIG. 2 ) that is perpendicular to the auditorium floor. The coordinates of the seat locations are determined relative to fixed point(s) in the auditorium; usually a set of distances measured from the front and left walls of the auditorium. In the exemplary embodiment of  FIGS. 1 and 2  the origin of the three dimensional coordinate system coincides with the spotlight/camera  106 . As seen in Table 1, each of the chairs  104  of row A are offset from each other along the X axis, with a lager separation between the chair at location A 4  and A 5  accounting for the passageway between A 4  and A 5 . The Y coordinate is the same for the entire row A. Similarly, row B has the same X coordinates as row A; however the Y coordinate is shifted relative to row A. In addition, the seats in row B have a Z coordinate other than zero that indicates that row B is higher than row A, thereby implying there is a slope or terraced arrangement of the rows in the auditorium  100 . In  FIGS. 1 and 2  spotlight  108  is positioned to point at seat location B 2   110 .

     In  FIGS. 1 and 2  the computer system  112  is attached to, and controls via application system software, the movable narrow-beam low-wattage spotlight/camera  106  that changes direction/position corresponding to a set of coordinates received from the computer system  112 . The computer system  112  may be connected to the one or more spotlight/cameras  106  in a wired or wireless manner. The application system software processes transactions in the order in which they are received, repositioning the spotlight  108  to the seat location of the next person to ask a question, and activates the wireless microphone so that the question can be heard. Optionally, a video camera may be affixed below the movable spotlight  106  so that a video feed of the person asking the question can be included in the multimedia presentation so that the audience can see who is asking the current question. The movable spotlight  106  may be in a fixed position in the auditorium, or may be portable to cover alternative locations as necessary. If the movable spotlight  106  is not in a fixed location, the database  114  on the computer system  112  will be updated to contain the accurate location of the movable spotlight  106  with respect to fixed points in the room relative to unmoving objects, such as the front or left side wall. 
       FIG. 3  illustrates the trigonometric relationships for calculating a horizontal adjustment angle theta (θ) in the X-Y plane for aiming a spotlight or other audience identifiers according to embodiments of the invention. The formula for calculating the horizontal adjustment angle theta (θ) is arctan (|Y−Y 0 |/|X−X 0 |). 
       FIG. 4  illustrates the trigonometric relationships for calculating a vertical adjustment angle phi (Φ) in the Z plane for aiming a spotlight or other audience identifiers according to embodiments of the invention. The formula for calculating the vertical adjustment angle phi (Φ) is arctan ((Z 1 −H)/(√(|Y−Y 0 | 2 +|X−X 0 | 2 )), where H is the height above Z=0, and Z 1  is the height of the spotlight. The height H may correspond to a typical audience member height, or to the elevation of a row. 
       FIG. 5  illustrates a flowchart for implementing embodiments of the invention. The process starts (block  500 ) with the computer system running the application software receiving audience requests to ask question to the moderator or speaker (block  502 ). The computer system records the order in which the audience question requests were received in a sequential list (block  504 ) with their respective position identifiers (block  506 ). The computer system utilizes the position identifiers to recall coordinates of audience member seats from a position database (block  508 ). The computer system sends the sequential list of audience requests to answer questions to the moderator or speaker (block  510 ). The computer system calculates movement commands to actuate one or more spotlight/cameras, based on the coordinates of audience member seat locations, in response to audience member recognition by the moderator or speaker (block  512 ) that actuates the spotlight/cameras to highlight or focus on the audience member recognized by the moderator or speaker (block  514 ). The computer system turns on the microphone of the recognized audience member (block  516 ). If there are no further audience members in the sequential list wishing to ask questions (decision block  518  is No) the process ends (block  522 ). 
     However, if there are additional audience members in the sequential list awaiting to ask questions (decision block  518  is Yes) the microphone of the current recognized audience member is turned off in response to the recognition of the next sequential audience member by the moderator or speaker (block  520 ), and the computer system sends the coordinates of next sequential audience member seat location to one or more spotlight/cameras in response to recognition of the next audience member by the moderator or speaker (block  512 ), to actuate the spotlight/cameras to highlight or focus on the next audience member recognized by the moderator or speaker (block  514 ). The computer system turns on the microphone of the recognized audience member (block  516 ). If there are no further audience members in the sequential list wishing to ask questions (decision block  518  is No) the process ends (block  522 ). If there are further audience members in the sequential list awaiting their turn to ask a question (decision block  518  is Yes) the process continues until the sequential list is exhausted and the end point is reached (block  522 ). 
     The capabilities of the present invention can be implemented in software, firmware, hardware or some combination thereof. 
     As one example, one or more aspects of the present invention can be included in an article of manufacture (e.g., one or more computer program products) having, for instance, computer usable media.
