     Communications media may typically embody computer-readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and include any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communications media include wired media, such as a wired network and a direct-wired connection, and wireless media such as acoustic, RF, optical, and infrared media. 
     The system memory  130  includes computer storage media in the form of volatile and nonvolatile memory such as ROM  131  and RAM  132 . A RAM may include at least one of a DRAM, an EDO DRAM, a SDRAM, a RDRAM, a VRAM, and/or a DDR DRAM. A basic input/output system (BIOS)  133 , containing the basic routines that help to transfer information between elements within the computing device  110 , such as during start-up, is typically stored in ROM  131 . RAM  132  typically contains data and program modules that are immediately accessible to or presently being operated on by processing unit  120 . By way of example, and not limitation,  FIG. 2  illustrates an operating system  134 , application programs  135 , other program modules  136 , and program data  137 . Often, the operating system  134  offers services to applications programs  135  by way of one or more application programming interfaces (APIs) (not shown). Because the operating system  134  incorporates these services, developers of applications programs  135  need not redevelop code to use the services. Examples of APIs provided by operating systems such as Microsoft&#39;s “WINDOWS” are well known in the art. 
     The computing device  110  may also include other removable/non-removable, volatile/nonvolatile computer storage media products. By way of example only,  FIG. 2  illustrates a non-removable non-volatile memory interface (hard disk interface)  140  that reads from and writes for example to non-removable, non-volatile magnetic media.  FIG. 2  also illustrates a removable non-volatile memory interface  150  that, for example, is coupled to a magnetic disk drive  151  that reads from and writes to a removable, non-volatile magnetic disk  152 , and/or is coupled to an optical disk drive  155  that reads from and writes to a removable, non-volatile optical disk  156 , such as a CD ROM. Other removable/nonremovable, volatile/non-volatile computer storage media that can be used in the exemplary operating environment include, but are not limited to, magnetic tape cassettes, memory cards, flash memory cards, DVDs, digital video tape, solid state RAM, and solid state ROM. The hard disk drive  141  is typically connected to the system bus  121  through a non-removable memory interface, such as the interface  140 , and magnetic disk drive  151  and optical disk drive  155  are typically connected to the system bus  121  by a removable non-volatile memory interface, such as interface  150 . 
     The drives and their associated computer storage media discussed above and illustrated in  FIG. 2  provide storage of computer-readable instructions, data structures, program modules, and other data for the computing device  110 . In  FIG. 2 , for example, hard disk drive  141  is illustrated as storing an operating system  144 , application programs  145 , other program modules  146 , and program data  147 . Note that these components can either be the same as or different from the operating system  134 , application programs  135 , other program modules  136 , and program data  137 . The operating system  144 , application programs  145 , other program modules  146 , and program data  147  are given different numbers here to illustrate that, at a minimum, they are different copies. A user may enter commands and information into the computing device  110  through input devices such as a microphone  163 , keyboard  162 , and pointing device  161 , commonly referred to as a mouse, trackball, or touch pad. Other input devices (not shown) may include a joystick, game pad, satellite dish, and scanner. These and other input devices are often connected to the processing unit  120  through a user input interface  160  that is coupled to the system bus, but may be connected by other interface and bus structures, such as a parallel port, game port, or a universal serial bus (USB). A monitor  191  or other type of display device is also connected to the system bus  121  via an interface, such as a video interface  190 . In addition to the monitor, computers may also include other peripheral output devices such as speakers  197  and printer  196 , which may be connected through an output peripheral interface  195 . 
     The computing system environment  100  may operate in a networked environment using logical connections to one or more remote computers, such as a remote computer  180 . The remote computer  180  may be a personal computer, a server, a router, a network PC, a peer device, or other common network node, and typically includes many or all of the elements described above relative to the computing device  110 , although only a memory storage device  181  has been illustrated in  FIG. 2 . The network logical connections depicted in  FIG. 2  include a local area network (LAN) and a wide area network (WAN), and may also include other networks such as a personal area network (PAN) (not shown). Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets, and the Internet.

       FIG. 4  illustrates an example of an operational flow  400  implemented in an environment that includes a person interacting with an electronic device using a user direct-input device. In an alternative embodiment, the environment that includes a person interacting with an electronic device using a user direct-input device further includes environment that includes a person viewing content displayed by an electronic device and directly interacting with the electronic device using a user direct-input device.  FIG. 4  and several following figures may include various examples of operational flows, discussions, and explanations with respect to the above-described environment  200  of  FIG. 3 , and/or with respect to other examples and contexts. However, it should be understood that the operational flows may be executed in a number of other environments and contexts, and/or in modified versions of  FIG. 3 . Also, although the various operational flows are illustrated in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, and/or may be performed concurrently. 
     After a start operation implemented in the environment that includes a person viewing content displayed by an electronic device using a user direct-input device, the operational flow  400  includes an observation operation  410 . The observation operation detects a reaction by the person to a displayed first content. The observation operation may be implemented using the reaction detector circuit  210 , and/or the response sensing apparatus  206 . An analytical operation  450  determines a content attribute of the displayed first content. The analytical operation may be implemented using the analytic circuit  250 . A query operation  460  facilitates a search for a second content based on the detected reaction by the observation operation and on the determined content attribute by the investigation operation. The query operation may be implemented using the query circuit  260 . A broadcast operation  480  displays the second content in a manner perceivable by the person. The broadcast operation may be implemented using the display circuit  280 . The operational flow  400  then proceeds to an end operation. 
     In an embodiment, the observation operation  410  may be implemented using the reaction detector circuit  210  of  FIG. 3 . For example, optically based observation data of the person  205  may be acquired by the sensor  206 A, and/or sensor  206 B. Physiological based data of the person may be acquired by the wearable/mountable sensor  206 C. A circuit in the response sensing apparatus  206  may transform data acquired by the sensors  206 A- 206 C into data indicative of a response by the person to the displayed first content. For example, a response may include at least one of a change in breathing rate, a change in heart rate, eye movements, facial movements, gaze direction and/or time, or a brain wave pattern. Another circuit in the response sensing circuit may detect a reaction by the person to a displayed first content based on the data indicative of a response by the person to the displayed first content. For example, a facial response that includes the person moving the ends of their lips above the center portion of the lips may be detected as a “smile” reaction or a “positive” reaction. A facial response that includes the person moving the ends of the lips below the center portion of the lips may be detected as a “frown” reaction or a “negative” reaction. The observation operation does not include data directly inputted by the person  205  using the user direct-input device  208 , such as keyboard, mouse, and voice commands entered by the user through the user direct-input device. However, in an alternative embodiment, the observation operation may include at least one of a quality, or a manner of the person&#39;s input of data using the direct-input device. For example, the observation operation may acquire data indicative of the person shouting a voice command without regard to a nature of the voice command, or the person striking keys of the keyboard particularly hard without regard to the keyed command or text. In a further embodiment, the observation operation may acquire sensor data indicative of the person shouting a voice command and associate a reaction with the nature of the voice command. For example, data indicative of a loud voice response may be associated with a spoken command “Delete this Web page” as a negative reaction to the content of the Web page. 
     In an embodiment, data indicative of a response may include data indicative of at least one of a person&#39;s gaze, attention, gaze dwell time, facial movements, eye movements, pupil dilation, physiological parameters (heart rate, respiration rate, etc.), stance, sub-vocalization (and other non-word audio), P-300 response, brain waves, brain patterns, or other detectable aspects. In another embodiment, data indicative of a response may include data indicative of at least one of a person&#39;s physiological, behavioral, emotional, voluntary, or involuntary response. In a further embodiment, data indicative of a response may include data acquired by functional near-infrared spectroscopy (fNIRS) indicative of a response. fNIRS data may be acquired by a fNIRS device, an embodiment of which is illustrated as the wearable/mountable sensor  206 C. 
     In another embodiment, the observation operation  410  detects a reaction by the person to a displayed first content by applying pattern recognition to the data indicative of a response by the person to the displayed first content. For example, a reaction may include a response that reveals the person  205 &#39;s feelings or attitude toward the displayed first content. In a further embodiment, the observation operation detects a reaction by the person to a displayed first content by applying pattern matching to the data indicative of a response by the person to the displayed first content. 
     In use, an embodiment of the operational flow  400  may illustrated by reference to  FIG. 3 . For example, a first content may be displayed to the person  205  on a portion of the display surface  209 , such as a screen of BlackBerry® or other PDA electronic device. In this example, the displayed first content may be a picture of a new car from a brother of the person  205 . Data indicative of a response by the person  205  to the displayed new car is acquired using at least one of sensors  206 A- 206 C. The observation operation  410  determines a reaction by the person to the displayed new car based on the data indicative of a response. If, for example, the data indicates an upward movement of the ends of the person&#39;s lips and an opening of their eyes, a positive reaction may be detected. The analytical operation  450  determines a content attribute of the displayed picture of the brother&#39;s new car. A content attribute may include at least one of a manufacturer of the new car, a color of the new car, or a body style of the new car, such as a convertible, coupe, four-door, or SUV. The query operation  460  facilitates a search for a second content based on the detected reaction (positive) and on the determined content attribute (convertible sports car). The search may be facilitated by communicating with an Internet based search service, such as Google, Yahoo, and/or Live Search. The broadcast operation  480  displays a second content in a manner perceivable by the person by receiving a result of the facilitated search that includes an indication of the second content, and displaying the second content using the display surface  209 . For example, the second content may include a picture of next year&#39;s model of the same car as the brother&#39;s new car.

     The foregoing detailed description has set forth various embodiments of the systems, apparatus, devices, computer program products, and/or processes using block diagrams, flow diagrams, operation diagrams, flowcharts, illustrations, and/or examples. A particular block diagram, operation diagram, flowchart, illustration, environment, and/or example should not be interpreted as having any dependency or requirement relating to any one or combination of components illustrated therein. For example, in certain instances, one or more elements of an environment may be deemed not necessary and omitted. In other instances, one or more other elements may be deemed necessary and added. 
     Insofar as such block diagrams, operation diagrams, flowcharts, illustrations, and/or examples contain one or more functions and/or operations, it will be understood that each function and/or operation within such block diagrams, operation diagrams, flowcharts, illustrations, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof unless otherwise indicated. In an embodiment, several portions of the subject matter described herein may be implemented via Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), digital signal processors (DSPs), or other integrated formats. However, those skilled in the art will recognize that some aspects of the embodiments disclosed herein, in whole or in part, can be equivalently implemented in circuits, as one or more computer programs running on one or more computers (e.g., as one or more programs running on one or more computer systems), as one or more programs running on one or more processors (e.g., as one or more programs running on one or more microprocessors), as firmware, or as virtually any combination thereof, and that designing the circuitry and/or writing the code for the software and or firmware would be well within the skill of one of skill in the art in light of this disclosure. In addition, those skilled in the art will appreciate that the mechanisms of the subject matter described herein are capable of being distributed as a program product in a variety of forms, and that an illustrative embodiment of the subject matter described herein applies regardless of the particular type of signal bearing medium used to actually carry out the distribution. Examples of a signal bearing medium include, but are not limited to, the following: a recordable type medium such as a floppy disk, a hard disk drive, a Compact Disc (CD), a Digital Video Disk (DVD), a digital tape, a computer memory, etc.; and a transmission type medium such as a digital and/or an analog communication medium (e.g., a fiber optic cable, a waveguide, a wired communications link, a wireless communication link, etc.). 
     Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware. 
     In a general sense, those skilled in the art will recognize that the various aspects described herein which can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or any combination thereof can be viewed as being composed of various types of “electrical circuitry.” Consequently, as used herein “electrical circuitry” includes, but is not limited to, electrical circuitry having at least one discrete electrical circuit, electrical circuitry having at least one integrated circuit, electrical circuitry having at least one application specific integrated circuit, electrical circuitry forming a general purpose computing device configured by a computer program (e.g., a general purpose computer configured by a computer program which at least partially carries out processes and/or devices described herein, or a microprocessor configured by a computer program which at least partially carries out processes and/or devices described herein), electrical circuitry forming a memory device (e.g., forms of random access memory), and/or electrical circuitry forming a communications device (e.g., a modem, communications switch, or optical-electrical equipment). Those having skill in the art will recognize that the subject matter described herein may be implemented in an analog or digital fashion or some combination thereof. 
     It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). 
     It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). 
     Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.” 
     The herein described aspects depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality. Any two components capable of being so associated can also be viewed as being “operably couplable” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components. 
     While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
