FIG. 1 depicts one embodiment of a user experience adjustment system in accordance with a preferred embodiment of the present invention;

FIG. 2 is a flow chart of one embodiment of a process for user experience adjustment in accordance with a preferred embodiment of the present invention; and

FIG. 3 is a flow chart of one embodiment of a process for user experience adjustment in accordance with a preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, an embodiment of a user experience adjustment system 10 in accordance with the present invention is shown. A user 12 may interact with a controllable event 14. Both the user 12 and the controllable event 14 interact with a computer system 16 that includes the user experience adjustment system 10. At least one physiological sensor 18 detects physiological data of the user 12 and provides the physiological data to the computer system 16. At least one environmental sensor 20 detects environmental data and provides the environmental data to the computer system 16. The user experience adjustment system 10 is provided to adjust the user's experience of the controllable event 14. User experience adjustment system 10 may be implemented as a software program product that can be stored in memory 22 and be executed on any type of computer system 16. A person skilled in the art will recognize that the invention may be implemented on one or more computer systems and this disclosure is not intended to limit such potential embodiments. In this illustrative embodiment, user experience adjustment system 10 includes: a somatic system 24, a mitigation system 26, a cognitive system 28, a user experience model system 30, an adjustment system 32, a community experience model system 34, a proximity system 36, an aggregation system 38, a mixing system 40, and a recommendation system 42.

Continuing to refer to FIG. 1 and referring to FIGS. 2 and 3, one embodiment of a process for user experience adjustment is shown. At SI the user 12 experiences the controllable event 14. Experiences may include pre-event experiences, during-event experiences, and post-event experiences of user. Controllable event 14 includes any event that may be modulated in a way that the user's experience of the controllable event 14 is adjusted.

Examples include, amusement park rides, movies, video games, virtual realities, immersive environments, building environmental systems, automobiles, and mass transportation. A person skilled in the art will readily recognize many user 12 interactions with controllable events 14. Modulating a controllable event 14 may include adjusting any parameter of the controllable event 14 that is experienced by the user 12. Examples of adjustable parameters may include, temperatures, G-forces, vibration, lighting levels, sound levels, olfactory levels, and other sensory parameters. A person skilled in the art will readily recognize many adjustable parameters for controllable events 14.

At least one physiological sensor 18 may detect physiological data of user 12 such as skin temperature, skin tone, degree of skin moisture (i.e. sweating), body temperature, degree of muscle tension, pupil size, eye movement, sounds, blood pressure, heart rate, respiration rate, brain activity, and any other physiological data of user. Physiological sensor 18 may be a hyperspectral collection device, acoustical collection device, heart rate monitor, spirometer, pupillometer, sphygmomanometer, electroencephalograph, and any other now known or to be developed physiological sensor 18. Physiological sensor 18 may be non- invasive wherein the physiological sensor 18 either does not make contact with the user 12 or does not break the skin of the user 12; or invasive wherein the physiological sensor 18 makes contact by breaking the skin of the user 12. A person skilled in the art will readily recognize that any number of now known or to be developed physiological sensors 18 may be utilized.

In one embodiment, somatic system 24 may receive physiological data from at least one physiological sensor 18. At S2, somatic system 24 may determine a user somatic state. Somatic system 24 may correlate physiological data with experiences of user 12 in interaction with the controllable event 14.

In one embodiment, mitigation system 26 may receive environmental data from at least one environmental sensor 20. Mitigation system 26 may interpret the environmental data and send mitigation data to somatic system 24 to adjust physiological data for environmental factors. For example, environmental data may include ambient temperature of the controllable event 14. Comparatively hot ambient temperatures may saturate infrared wavelength collection. If the ambient temperature is comparatively hot for the user 12 then readings of skin temperature as a measure of the user's experience of the controllable event 14 would be mitigated for the hot ambient temperature. In an embodiment using more than one physiological sensor 18, mitigation system 26 may compare signals from each physiological sensor 18 and may boost one or more of the signals for proportionate measurements. For example, mitigation system 26 may evaluate the quality of each respective signal and band. Mitigation system 26 may boost signal quality proportionately within each modality as well as between each modality.

In one embodiment, cognitive system 28 may receive reports of experience from user 12 in interaction with the controllable event. For example, the user 12 may answer questions on how he or she is feeling before, during, and after an amusement park ride. At S3, cognitive system may determine a user cognitive state.

User experience model system 30 may receive the user cognitive state and the user somatic state. At S4, user experience model system 30 may determine a user experience model for the user 12 based upon the user cognitive state and the user somatic state. For example, user experience model system 30 may correlate a report from the user 12 of being frightened with a specific detected heart rate of the user 12.

At S5, user experience model system 30 may correlate at least one user hypothesis with the user experience model. A plurality of user hypotheses may be stored in a user experience database 44. Each user hypothesis may be a potential experience for a user 12. Each hypothesis may be created from user experience history (i.e., one or more previous user experiences). In one embodiment, each hypothesis may be generated through supervised and offline learning by the user 12. Each previous user experience correlates a previous user cognitive state and a previous user somatic state. For example, after the user 12 experiences each controllable event 14 the user 12 may label the experience. For example, the label may indicate if the user 12 liked the experience or not, whether the experience was frightening or not, pleasing or not, and any other user experience assessments.

At S6, adjustment system 32 may receive at least one user hypothesis and may adjust the controllable event 14 in order to adjust the user's 12 experience of the controllable event 14. Alternatively, user 12 may receive at least one hypothesis and may instruct adjustment system 32 to adjust the user's 12 experience of the controllable event 14.

User experience model, user cognitive state, user somatic state, and user hypotheses may be stored in a user experience database 44. It should be readily apparent that one user 12 may experience a plurality of different controllable events or the same controllable event a plurality of times.

A plurality of additional users 46 may experience a plurality of different controllable events or the same controllable event a plurality of times. For each additional user 46 and each controllable event experienced by each additional user 46, user experience adjustment system 10 may determine and store an additional user experience model, an additional user cognitive state, an additional user somatic state, and at least one additional user hypothesis. At S7, community experience model system 34 may determine one or more community experience models and, at S8, correlate additional user hypotheses with each community experience model.

Proximity system 36 may receive the user hypotheses and the additional user hypotheses. At S9, proximity system 36 compares the user hypotheses with the additional user's hypotheses and, as a result of the comparing, at S10, determines a set of exploratory hypotheses and, at SI 1, determines a set of constrained hypotheses. Constrained hypotheses may predict similar user experiences and are likely to be experiences that the user 12 is accustomed to. Exploratory hypotheses may predict different user experiences and are likely to be experiences that are new for the user 12. At SI 2, aggregation system 38 aggregates hypotheses from the constrained hypotheses and the exploratory hypotheses. In one embodiment, prior to aggregation, mixing system 40 may apply a mixing coefficient to the constrained hypotheses and the exploratory

hypotheses. Mixing coefficient may be set by user to reflect the degree the user 12 wants each experience to be adjusted towards exploratory hypotheses or towards constrained hypotheses. For example, the more the user 12 wants to adjust experiences towards predictable and known, then the mixing coefficient would favor constrained hypotheses and the more the user 12 wants to adjust experiences towards adventuresome and unknown, then the mixing coefficient would favor exploratory hypotheses. Aggregate hypotheses with mixes of a larger proportion of constrained hypotheses may be familiar to the user 12.

Aggregate hypotheses with mixes of a larger proportion of exploratory hypotheses may be newer to the user 12.

At SI 3, recommendation system 42 receives the aggregate hypotheses and recommends adjustment to the controlled event based upon the received aggregate hypotheses. User 12 may select a recommendation or recommendation system 42 may select a recommendation based upon a user profile. At SI 4, adjustment system adjusts the controllable event 14 based on the selected recommendation. In FIG. 1, computer system 16 includes a user experience adjustment system 10 stored in a memory 22 and described herein. Computer system 16 is shown including a central processing unit (CPU) 52 (e.g., one or more processors), an input/output (I/O) component 54 (e.g., one or more I/O interfaces and/or devices), and a communications pathway 56. In one embodiment, CPU 52 executes program code, such as user experience adjustment system 10, which is at least partially embodied in memory 22. While executing program code, CPU 52 can process data, which can result in reading and/or writing the data to/from memory 22 and/or I/O component 54 for further processing. Communications pathway 56 provides a communications link between each of the components in computer system 16. I/O component 54 can comprise one or more human I/O devices or storage devices, which enable user 12 to interact with computer system 16 and/or one or more communications devices to enable user 12 to communicate with computer system 16 using any type of communications link. To this extent, user experience adjustment system 10 can manage a set of interfaces (e.g., graphical user interface(s), application program interface, and/or the like) that enable human and/or system interaction with user experience adjustment system 10. In any event, computer system 16 can comprise one or more general purpose computing articles of manufacture (e.g., computing devices) capable of executing program code installed thereon. As used herein, it is understood that "program code" means any collection of instructions, in any language, code or notation, that cause a computing device having an information processing capability to perform a particular function either directly or after any combination of the following: (a) conversion to another language, code or notation; (b) reproduction in a different material form; and/or (c) decompression. To this extent, user experience adjustment system 10 can be embodied as any combination of system software and/or application software. In any event, the technical effect of computer system 16 is to adjust a user's experience of a controllable event.

Further, user experience adjustment system 10 can be implemented using a set of modules 50. In this case, a module 50 can enable computer system 16 to perform a set of tasks used by user experience adjustment system 10, and can be separately developed and/or implemented apart from other portions of user experience adjustment system 10. User experience adjustment system 10 may include modules 50 which comprise a specific use machine/hardware and/or software. Regardless, it is understood that two or more modules 50, and/or systems may share some/all of their respective hardware and/or software.

Further, it is understood that some of the functionality discussed herein may not be implemented or additional functionality may be included as part of computer system 16.

When computer system 16 comprises multiple computing devices, each computing device may have only a portion of user experience adjustment system 10 embodied thereon (e.g., one or more modules 50). However, it is understood that computer system 16 and user adjustment system 10 are only representative of various possible equivalent computer systems that may perform a process described herein. To this extent, in other embodiments, the functionality provided by computer system 16 and user experience adjustment system 10 can be at least partially implemented by one or more computing devices that include any combination of general and/or specific purpose hardware with or without program code. In each embodiment, the hardware and program code, if included, can be created using standard engineering and programming techniques, respectively. Regardless, when computer system 16 includes multiple computing devices, the computing devices can communicate over any type of communications link. Further, while performing a process described herein, computer system 16 can communicate with one or more other computer systems using any type of communications link. In either case, the

communications link can comprise any combination of various types of wired and/or wireless links; comprise any combination of one or more types of networks; and/or utilize any combination of various types of transmission techniques and protocols.

As discussed herein, user experience adjustment system 10 enables computer system 16 to provide processing instructions for adjusting a user's experience of a controllable event. User experience adjustment system 10 may include logic, which may include the following functions: somatic system 24, mitigation system 26, cognitive system 28, user experience model system 30, adjustment system 32, community experience model system 34, proximity system 36, aggregation system 38, mixing system 40, and recommendation system 42. In one embodiment, user experience adjustment system 10 may include logic to perform the above-stated functions. Structurally, the logic may take any of a variety of forms such as a field programmable gate array (FPGA), a microprocessor, a digital signal processor, an application specific integrated circuit (ASIC) or any other specific use machine structure capable of carrying out the functions described herein. Logic may take any of a variety of forms, such as software and/or hardware. However, for illustrative purposes, user experience adjustment system 10 and logic included therein will be described herein as a specific use machine.
