DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings, which form a part thereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
Referring to the figures generally, various embodiments disclosed herein relate to a feedback system (e.g., a haptic feedback system, an audible/visual feedback system, combinations thereof, etc.) intended to enhance the situational awareness of a user in a given situation (e.g., in a video game, in a real-world application, etc.). When a threat or other object (e.g., opponent, enemy, etc.) is within the proximity of a user (or virtual character) of the feedback system, feedback (e.g., haptic feedback, audible feedback, visual feedback, etc.) is provided to the user to make him/her aware of objects not in his/her field of view or to identify an object in the user's field of view as a threat. Ideally, the feedback becomes second nature to the user of the feedback system such that he/she develops an intuitive sense of the surroundings or a virtual environment. The feedback may be haptic, audible, visual, or combinations thereof, among other possibilities.
For example, video game players are not always aware of objects, other players, and/or threats within a video game, due to limitations of field of vision, distractions, skill, etc. The systems disclosed herein in accordance with various embodiments provide players with feedback regarding a primary object (e.g., a character used by the video game player, a vehicle driven by the video game player, etc.) and a secondary object (e.g., other virtual characters, vehicles, dangers, remote from the primary object, a distal object, etc.). The feedback may be generated based on various data regarding the primary object, secondary objects, a surrounding virtual environment, etc., and may be provided so as to provide an indication of a virtual distance, a virtual direction, an affiliation, a threat level (or nature of the secondary object), a relative velocity, an absolute velocity, a relative acceleration, an absolute acceleration, and the like between the primary object and the secondary object.
Similarly, users may likewise use the systems disclosed herein for real-world applications such as driving, treatment for sight or hearing-impaired persons, aviation, sports, combat, etc. For example, a paintball player may not always recognize/see other players of an opposing team or may have an opposing player sneak up from a side or rearward position. The systems disclosed herein in accordance with various embodiments are configured to provide a user of the feedback system with feedback (e.g., haptic feedback, audible feedback, visual feedback, etc.), thereby increasing the user's awareness of potential threats or other information that may be conveyed through audible, tactile, and/or visual stimulation.
According to the example embodiment shown in FIGS. 1-5C, feedback system 10 (e.g., situational awareness system, etc.) is configured as a video game/electronic game feedback system. In one embodiment, feedback system 10 is configured to provide feedback to a user playing a video game (e.g., a first person shooter game, a racing game, a fighting game, a console game, a computer game, a mobile game, etc.).

In some embodiments, sensor system 90 is configured to acquire and provide user data regarding the user of the primary object to sensor module 50. Sensor system 90 may communicate with sensor module 50 in a variety of ways, using any suitable wired and/or wireless communications protocols. According to an example embodiment, sensor system 90 includes a sensor, such as a camera, motion sensor, and/or another device, configured to acquire the user data. In one embodiment, sensor system 90 includes an external sensor system (e.g., located remote from the user, etc.). In other embodiments, sensor system 90 includes a wearable sensor system. The user data may include data regarding an orientation and a movement of at least one of a head, a torso, an arm, and a leg of the user. In one embodiment, the first data of the primary object is based on the user data. For example, the orientation and the movement of the user may be used to control the orientation and movement of a virtual character in a virtual environment.
Referring still to FIG. 1, input device 80 is configured to receive an input from the user during the video game. The first data of the primary object is based on the input from input device 80, according to an example embodiment. By way of example, input device 80 may be configured to receive at least one of touch inputs, audible inputs, and motion inputs provided though the movement of input device 80 such that a virtual character performs some action (e.g., moves, turns, shoots, etc.). As shown in FIGS. 5A-5C, input device 80 may include a variety of input devices. As shown in FIG. 5A, input device 80 may include or be a hand-held input device, shown as controller 82. In one embodiment, controller 82 is configured to receive touch inputs in the form of button commands. Additionally or alternatively, controller 82 is configured to receive motion inputs through the user repositioning the controller 82 (e.g., a throwing motion, a punching motion, etc.). As shown in FIG. 5B, input device 80 may include or be a voice recognition device (e.g., a headset/microphone device, etc.), shown as headset 84. Headset 84 may be configured to receive voice commands (e.g., audible inputs, etc.) from the user. As shown in FIG. 5C, input device 80 may include or be a touch sensitive input device, shown as touch sensitive device 86. As shown in FIG. 5C, touch sensitive device 86 is hemispheric in shape. In other embodiments, touch sensitive device 86 is another shape. A user of feedback system 10 may provide touch inputs to the exterior of the touch sensitive device 86 for providing input to control the primary object. In some embodiments, touch sensitive device 86 is configured to provide feedback to a user of feedback system 10. For example, portions of the exterior of touch sensitive device may vibrate or illuminate to provide a user with an enhanced awareness of the virtual environment. In another embodiment, input device 80 includes a wearable input device configured to receive motion inputs from the movement of the user and/or touch inputs. In an alternative embodiment, input device 80 and feedback device 100 are included in a single device, as is described more fully herein.
Processing circuit 30 is configured to control operation of feedback device 100 via feedback module 60 based on the data (e.g., first data, second data, event data, etc.) received by sensor module 50. As shown in FIGS. 3A-3C, feedback device 100 may include a variety of wearable feedback devices. The wearable feedback devices include a plurality of feedback elements, shown as elements 102. In one embodiment, elements 102 are configured to provide haptic feedback to the user such that a user has an enhanced situational awareness. Referring to FIG. 3A, in one embodiment, feedback device 100 includes a wearable headgear device, shown as headgear 104, configured to rest on the head of the user of feedback system 10. As shown in FIG. 3A, headgear 104 includes a plurality of elements 102 disposed about headgear 104. In one embodiment, the plurality of elements 102 are equally spaced about headgear 104. In other embodiments, the plurality of elements 102 are selectively positioned around headgear 104 so as to correspond in location to desired anatomical features (e.g., ears, temple, forehead, nape, crown, etc.) of the user. The size of headgear 104 may be varied to fit various users and to accommodate various types of elements 102 (e.g., haptic, visual, audible, etc.).
Referring now to FIG. 3B, feedback device 100 includes a band, shown as band 106, in some embodiments. Band 106 may include one or more elements 102. In one embodiment, band 106 includes a single element 102. In other embodiments, band 106 includes a plurality of elements 102. In one embodiment, elements 102 are equally spaced about band 106. In other embodiments, elements 102 are selectively positioned along band 106 so as to correspond in location to desired parts of a user's body (e.g., an ear or temple area of the head, a wrist, etc.). The size of band 106 may be varied to fit various users or body parts (e.g., a head, a wrist, an ankle, a waist, etc.) and/or to accommodate various types of elements 102. In one embodiment, band 106 is a head band. In other embodiments, band 106 may be a wrist band (e.g., a watch, a bracelet, etc.), an ankle band, an arm band, a leg band, a torso band (e.g., a belt, etc.), or a band to extend about another portion of a user's body.
Referring to FIG. 3C, in other embodiments, feedback device 100 includes an article of clothing, shown as article of clothing 108. As shown in FIG. 3C, article of clothing 108 is a shirt. In other embodiments, article of clothing 108 may be pants, a sock, a shoe, or a glove. In one embodiment, the plurality of elements 102 are equally spaced about article of clothing 108. In other embodiments, the plurality of elements 102 are selectively positioned around article of clothing 108 so as to correspond in location to desired anatomical features (e.g., chest, back, etc.) of the user. The size of article of clothing 108 may be varied to fit various users and to accommodate various types of haptic elements 102. In further embodiments, feedback device 100 includes a combination of articles of clothing 108, including a shirt, pants, a sock, a shoe, and/or a glove. In yet further embodiments, feedback device 100 includes a combination of devices, including headgear 104, one or more bands 106, and/or one or more articles of clothing 108.
According to an example embodiment, elements 102 may be or include a vibratory element configured to provide haptic feedback (e.g., vibrations, mechanical stimulations, etc.) to a user regarding a secondary object or event. For example, element 102 in some embodiments is or includes a vibration device or similar component. In another embodiment, elements 102 of feedback device 100 include an audible element configured to provide audible feedback to a user regarding a secondary object or event. For example, in some embodiments, element 102 is or includes a speaker or similar component. In further embodiments, elements 102 of feedback device 100 include a visual element configured to provide visual feedback to a user regarding a secondary object or event. For example, in some embodiments, element 102 is or includes a light source (e.g., an LED, etc.). In yet further embodiments, feedback device 100 includes a combination of feedback elements, including one or more of haptic, audible, visual, and the like.
Feedback device 100 may provide a user of feedback system 10 with enhanced awareness of his/her surroundings such that he/she may provide an input to input device 80 that corresponds with the feedback. For example, the user may provide a touch input and/or motion input to controller 82 to move a virtual character a certain direction, perform a specific task, or the like based on the feedback received. By way of another example, the user may provide a voice command to headset 84 to control the actions of the primary object, provide team members with information regarding enemies (e.g., players on another team, etc.) based on the feedback, and the like based on the received feedback from feedback device 100. By way of yet another example, the user may provide touch sensitive inputs to touch sensitive device 86. The relative locations of touch sensitive device 86 may substantially correspond to the feedback provided by feedback device 100. For example, the user may feel a vibratory sensation on the back of his/her head from headgear 104. The user may associate the location of the haptic feedback on their head to the near side (i.e., the side closest to the user, etc.) of touch sensitive device 86. By touching the corresponding location on touch sensitive device 86, the virtual character may move accordingly. For example, the virtual character may turn towards the inputted direction, begin moving in the inputted direction, or start shooting in the inputted direction, among other alternatives.
In alternative embodiments, feedback device 100 and input device 80 are provided by a single device such that the single device provides both input to processing circuit 30 (e.g., to control the virtual character, etc.) and output/feedback to the user (e.g., to provide enhanced situational awareness, etc.). For example, touch sensitive device 86 may be integrated into headgear 104 such that a user may provide a touch input directly in the location the feedback is experienced. By way of example, if haptic feedback is provided to the temple of the user (e.g., indicating an enemy to their side, etc.), the user may touch the temple location on their head, and touch sensitive device 86 may take appropriate action (e.g., turn in the direction of the touch input, etc.). In some embodiments, feedback devices 100 such as headgear 104, band(s) 106, and/or article(s) of clothing 108 are configured to provide input to feedback system 10 through motion/movement of the user. By way of example, feedback devices 100 may include motion sensors that track the movement of a portion of the user (e.g., an arm, a leg, etc.). For example, a user may turn his/her head and headgear 104 may track the motion and provide input such that the virtual character turns or looks accordingly. By way of another example, the user may be wearing bands 106 on his/her wrists such that bands 106 provide input regarding the location of the virtual characters hands/arms based on the movement of the users hands/arms (e.g., such as the motion of the user's arm when throwing a punch in a fighting game, etc.). In some embodiments, both sensor system 90 (e.g., via a camera system, etc.) and feedback device 100 (e.g., headgear 104, bands 106, clothing 108, etc.) track the movement of the user. Feedback system 10 may then compare the motion data gathered by both sensor system 90 and feedback device 100 to provide a more accurate input to control movements and actions of the primary object.
Referring now to FIG. 2, elements 102 are configured to be selectively and dynamically activated and deactivated based on an orientation of the head of the primary object (e.g., P1, etc.) relative to the secondary object(s) (e.g., O1, O2, etc.). As shown in FIG. 2, secondary objects O1 and O2 are in close proximity (e.g., pose a possible threat, etc.) to primary object P1 within virtual environment 76, while secondary object O3 is not within close proximity (e.g., does not pose a threat, substantially far from primary object P1, etc.). In one embodiment, feedback device 100 provides the user with feedback such that the user has a heightened awareness of the secondary objects and/or threats outside of his/her field of view. For example, as shown in FIG. 2, secondary object O2 is not within the field of view of primary object P1 such that user is not able to see secondary object O2 on display device 70. In other embodiments, feedback device 100 further provides the user with feedback for secondary objects within the user's field of view to reinforce the intuitive understanding of what each vibration (or other feedback signal such as audible or visual) represents as described more fully herein. For example, as shown in FIG. 2, secondary object O1 is within the field of view of primary object P1 such that user is able to see secondary object O1 on display device 70. In one embodiment, feedback device 100 provides the user with feedback when the primary object P1 and a secondary object are not in contact. In some embodiments, feedback device 100 also provides the user with feedback when the primary object P1 and a secondary object are in contact (e.g., a punch or kick hitting the primary object, etc.).
According to one embodiment, feedback device 100 provides two dimensional information (e.g., left, right, front, back, etc.) to a user regarding the position of the secondary object in relation to the primary object. For example, if the secondary object is behind the primary object, feedback device 100 may provide haptic feedback (or another type of feedback) via elements 102 to a rear portion of the user (e.g., back, rear of head, rear of neck, etc.) to make the user aware of the unseen secondary object behind the primary object. In other embodiments, feedback device 100 provides three dimensional information (e.g., up, down, up at an angle, etc.) to the user regarding the position of the secondary object in relation to the primary object. For example, if the secondary object is to the side and above the primary object, feedback device 100 may provide haptic feedback via elements 102 to a side portion of the user (e.g., between the top and side of the user's head, etc.). In another example, the feedback system 100 may provide visual feedback via elements 102 by flashing a light in the users peripheral vision (e.g., on the side the secondary object is located, etc.) or emitting an audible tone in an ear corresponding to a location of the secondary object with respect to the users view of the virtual environment (e.g., emitting an audible tone in the right ear of a user when a secondary object is located somewhere on the right side of the users view of the virtual environment, etc.).
According to an example embodiment, elements 102 of feedback device 100 provide metadata denoting situations within the video game (i.e., not only directional information, etc.). By way of example, feedback module 60 may be configured to vary the frequency, amplitude, and/or waveform of vibrations of elements 102 to provide indications of different types of information to the user regarding the primary object and/or the secondary object based on the first data, the second data, and/or the event data. In one embodiment, elements 102 denote a change in relative position between the primary object and the secondary object. In further embodiments, the feedback is configured to provide an indication of a relative distance, a relative velocity, an absolute velocity, a relative acceleration, and/or an absolute acceleration between the primary object and the secondary object. For example, the frequency of vibratory feedback may be increased or decreased with the relative velocity of the secondary object (e.g., another user controlled character, computer controller character or object, etc.), and the amplitude of the vibratory feedback may be increased/decreased with the relative distance between or proximity of potentially threatening objects. As such, in one embodiment, as the relative velocity between the primary object and the secondary object increases and the distance decreases, the vibratory feedback may increase in frequency and amplitude. Conversely, should the user take action to avoid the secondary object (e.g., by slowing down, changing direction, etc.) to decrease the relative velocity between users and/or increase the distance, the vibratory warning may decrease in frequency and amplitude.
In yet further embodiments, the feedback is configured to provide an indication of an affiliation and/or a threat level/nature of the secondary object. For example, non-threatening objects (e.g., allies, teammates, etc.) may be ignored (e.g., no feedback is provided, etc.). On the other hand, threatening objects (e.g., enemies, players on other team, opponents, etc.) may cause control system 20 to provide feedback to the user via feedback device 100. Likewise, the feedback may vary in amplitude, frequency, and/or waveform based on a threat intensity. For example, a high threat object (e.g., a boss character, a high skilled player, etc.) may cause a more frequent and higher amplitude vibratory response from elements 102. Conversely, a low threat object (e.g., low skilled player, minion, etc.) may cause a less frequent and lower amplitude vibratory response. In some embodiments, feedback device 100 further provides the user with various intensities of feedback based on the direction between the primary object and the secondary object relative to an orientation of the primary object and/or an orientation of the secondary object. For example, a secondary object may be classified as a high threat object if the secondary object is looking at the primary object or a low threat object if the secondary object is looking away from the primary object. As another example, a secondary object may be classified as a high threat object if the primary object is not looking at the secondary object or a low threat object if the primary object is looking at the secondary object.
In some embodiments, feedback device 100 is configured to provide directional information to the user. In one embodiment, the directional information indicates a proposed direction of movement of the primary object. By way of example, in a racing game, feedback device 100 may provide directional cues to notify the user of an upcoming turn in a race track. By way of another example, feedback device 100 may provide the user with haptic feedback to propose a direction of travel such that the user leads a virtual character along a certain path, towards a secondary object, away from a threat, among other possibilities. In other embodiments, the directional information indicates a direction of virtual gravity. For example, in some games, a virtual character may become disoriented (e.g., from an explosion, etc.) and not be able to gain bearing for a certain amount of time. In this instance, feedback device 100 may provide directional cues to reorient the user of the virtual character with the virtual environment (e.g., such as the direction of virtual gravity, etc.). In additional embodiment, the directional information provides an indication of a specific point or locations of interest. For example, the points may be static points such as a home base or planet, or the points may be moving such as targets (e.g., enemies, etc.) that the user may be tracking or being tracked by. The static points may be valuable during combat or other types of play to orient the user with where the user is headed or with what the user is guarding during moments of disorientation.
In some embodiments, feedback system 10 is configured to recognize boundaries and provide feedback through feedback device 100 based on the respective boundary. For example, feedback device 100 may warn a user of an upcoming cliff or obstacle. By way of another example, feedback device 100 may lead a user to a doorway or passage. By way of yet another example, feedback device 100 may recognize and notify a user of walls or virtual boundaries (e.g., such as in dark caves, holorooms, etc.) that the user may or may not be able to see.
In some embodiments, feedback system 10 monitors the status of a user's team or enemy team and relays information regarding the status to each user. For example, feedback system 10 may provide feedback to a user when a player is killed via feedback device 100. In one embodiment, feedback device 100 provides haptic feedback to inform the players of how many players are alive or dead via a number of vibrations. In other embodiments, the feedback may be an auditory message (e.g., such as “player X has been killed”, “five players remain”, etc.).
Parameters in which the feedback is provided to a user may be modified by at least one of the user based on preference and control system 20 based on a chosen difficulty setting (e.g., easy, medium, hard, etc.), according to an example embodiment. For example, a range (e.g., distance, etc.) in which the user is first alerted of a secondary object may be altered via a user chosen setting or predefined by the game difficulty selected by the user. Similarly, the user may choose the type of objects for which to be alerted about (e.g., enemies, friendlies, based on threat level, nature, etc.). In one embodiment, a squelch function is used to tune out (e.g., suppress, etc.) excess noise (e.g., non-threatening objects, etc.).
In other embodiments, feedback device 100 includes a speaker (e.g., external speaker, head phones, ear buds, etc.) configured to provide audible feedback (e.g., an audible warning or notification, etc.) to a user. The speaker may be implemented in any suitable location, and any suitable number of speakers may be utilized. In some embodiments, multiple speakers may be utilized. The speakers may be worn on or within one or both ears of a user. In one embodiment, the speakers are stereophonic such that a stereophonic warning is provided to users by way of feedback device 100. While in some embodiments the speakers are worn by a user (e.g., on an ear, etc.), in other embodiments, the speakers are carried by another piece of equipment, such as headgear 104, a vehicle, etc. The pitch, volume, tone, frequency, and other characteristics of an audible warning/notification may be varied to provide indications of direction, relative position, relative velocity, absolute velocity, relative acceleration, absolute acceleration, affiliation, threat level, nature, and the like to the user.
In some embodiments, feedback system 10 uses multi-channel audio information to localize the origin of sounds in a game and converts the sound information to feedback (e.g., haptic feedback, etc.) that indicates the virtual spatial location of the audio to the user. Feedback device 100 may connect (via any suitable wireless or wired protocol) to an audio output of the machine (e.g., game console, computer, smart phone, tablet, audio receiver, etc.) and obtain three-dimensional audio information. Multi-channel audio operates by varying the intensity and timing of sounds to create the illusion that the sounds are being generated from a specific spatial location relative to the hearer. Feedback system 10, via processing circuit 30, may interpret raw multi-channel audio information and determine where sounds are arising from relative to the user. Processing circuit 30 may then convert the audio information into feedback to help the user better identify where the sounds are coming from. In turn, processing circuit 30 is configured to provide, for example, haptic feedback to a user via feedback device 100 to indicate specific range, elevation, and/or bearing information that may be substantially easier to interpret than audio coming from headphones or a surround sound system. This may be particularly useful in an electronic game that outputs multi-channel (e.g., 6-channel, etc.) audio where the user is only using stereo headphones. Converting the multi-channel audio information into haptic feedback may substantially increase a user's competitive advantage in the electronic game. The user may be able to more quickly identify, for example in a first-person shooter game, where shots are coming from than if the user were solely using the stereo headphones. For example, if a virtual character is being shot at in a first-person shooter game, and the user cannot locate where it is coming from, feedback device 100 may provide the user with haptic feedback to allow the user to identify the origin (i.e., the location relative to the virtual character, etc.) of the sound (e.g., a gunshot, etc.). This also facilitates the integration of feedback system 10 with an electronic game without the electronic game's source code supporting feedback system 10.
The same general concept may be generalized to convert many different types of in-game information into feedback. For example, many electronic games display a “bird's eye view” map, showing the location and/or orientation of the primary object, team members of the user of the primary object, and/or secondary objects (e.g., opponents, enemies, etc.) within a virtual environment. Processing circuit 30 may interpret this visual information and convert it to feedback, thereby not requiring the user to actually look at the in-game map. There are numerous other features expressed visually within an electronic game that may also be converted to feedback to be provided to a user of feedback system 10.
In further embodiments, feedback device 100 includes one or more lights configured to provide visual warnings or notifications to a user. For example, one or more lights (e.g., LEDs, etc.) may be provided within headgear 104 (e.g., to the peripheral side of each eye, etc.). A brightness, a color, a blinking frequency, or other characteristic of the light may be varied to provide indications of direction, relative position, relative velocity, absolute velocity, relative acceleration, absolute acceleration, affiliation, threat level, nature, and the like to the user.
According to an example embodiment, elements 102 of feedback device 100 (e.g., haptic elements, visual elements, audible elements, etc.) are activated based on conditions or settings within the game corresponding with the event data and/or actions taken by the primary and secondary object (e.g., indicated by the first data and the second data, etc.). The use and/or availability of feedback with a game may be controlled by control system 20 responsive to the event data, the first data, and/or the second data. In one embodiment, the availability of feedback is based on the game level/situation or a change thereof. By way of example, feedback may be disabled or scrambled (e.g., false feedback provided, miscalibrated, etc.) by control system 20 during a portion of a game to increase the difficulty. By way of another example, feedback may be disabled during a situation where the primary object (e.g., virtual character) becomes disoriented (e.g., from a flash bang grenade in a war game, etc.). By way of yet another example, as the user progresses through the game and reaches new checkpoints, milestones, and/or levels, the availability of the feedback may change (e.g., decrease, increase, etc.). For example, feedback may be disabled or hindered during a portion of the game when the primary object controlled by the user is facing a boss character or a character with a feature/ability/perk to disable/hinder feedback abilities.
In another embodiment, the availability of feedback is based on a primary object's or a user's experience, performance, and/or skills. For example, a virtual character with better attributes (e.g., strength, speed, aim, etc.), perks (e.g., special weapons, powers, etc.), and/or skills than other virtual characters may not be compatible with a feedback feature. In another example, a user may be rewarded the ability to activate feedback based on a level of skill (e.g., reaching a certain rank, level, prestige, etc.). In other embodiments, the availability of feedback is based on the performance of other users or secondary objects within the game. For example, if a secondary object is outperforming the primary object, the user of the primary object may be allowed to implement feedback capabilities, while the user of the secondary object may have feedback capabilities reduced or disabled.
In some embodiments, the availability of feedback is based on a current virtual environment. By way of example, feedback may be disabled in a harsh environment of the electronic game (e.g., during a storm, in a dark cave, etc.). In additional embodiments, the availability of feedback is based on a difficulty setting of the game. By way of example, a user playing a game on a relatively easy setting may be provided substantial amounts of feedback to enhance their awareness within the game and aid in the reduction of the difficulty. While a user playing a game on a relatively difficult setting may be provided with minimal amounts of feedback or none at all to increase the difficulty. In further embodiments, the availability of feedback is based on the purchase or acquisition of feedback within the game or from a game marketplace (e.g., an app store, etc.). For example, feedback may be treated like a special item or skill that is purchasable (e.g., via points/virtual money earned during game play, etc.) within the game to increase the awareness of the virtual character (i.e., the user of the virtual character, etc.) regarding the surrounding virtual environment and secondary objects. In another example, feedback may require an additional purchase not included with the game from a store (e.g., an electronics retail store, etc.) or online game marketplace. In other embodiments, the availability of feedback is based on an operational mode of feedback device 100 (e.g., on, off, an active state, an inactive state, etc.). In some embodiments, the availability of feedback is based on any combination of the aforementioned event data (e.g., a level, a situation, a difficulty setting, a current virtual environment, a performance level of the user, a performance level of other users, etc.).
In an alternative embodiment, the availability of feedback is based on an operational mode of feedback device 100. According to an example embodiment, feedback device 100 is operable in a first mode of operation (e.g., an active state, an on state, etc.) and a second mode of operation (e.g., an inactive state, a standby state, an off state, etc.). In one embodiment, the first operational mode and/or the second operational mode indicate a specified sensitivity setting for feedback device 100. The specified sensitivity setting may be user defined or processor controlled. The specified sensitivity setting may indicate an amount of feedback output for a given input (e.g., distance based, threat based, etc.). In another embodiment, the first operational mode and/or the second operational mode indicate a specified event responsiveness for feedback device 100 (e.g., an amount of feedback for certain events or situations, etc.). In other embodiments, the first operational mode and/or the second operational mode indicate a specified feedback presentation for feedback device 100 to provide to a user (e.g., visual, audible, or tactile feedback; a frequency, amplitude, etc.). In some embodiments, the first operational mode and/or the second operational mode indicate a specified availability for feedback device 100 to provide feedback to a user.
In one embodiment, the operational mode of feedback device 100 is controlled by a user (e.g., by pressing an on/off button, etc.). In another embodiment, the operational mode of feedback device 100 is controlled by control system 20. Control system 20 may be configured to reconfigure feedback device 100 between the active state and the inactive state based on at least one of the event data, the first data, user data, and the second data (as described above with regards to the availability of the feedback). In one embodiment, the possession, settings, or operational mode of the feedback device is represented within an electronic game by a tertiary object (e.g., an item the user may pick up or obtain with the primary object, etc.). For example, control system 20 may activate feedback capabilities in response to a user obtaining a certain item (representing feedback device 100) within a game.
According to another example embodiment, feedback device 100 is controlled by control system 20 to operate better (e.g., be more sensitive to surroundings, etc.) for some primary or secondary objects than others. For example, some enemies (e.g., other players, virtual characters, etc.) may not be detected as well as others, such as ninjas or leopards. In one embodiment, a user is able to purchase or acquire an invisibility/sneakiness skill or ability for a primary object such that an opponent's feedback device 100 does not notify the opponent of the user's primary object. In another embodiment, a user is able to purchase or acquire a disruption skill for a primary object such that an opponent's feedback device 100 provides false feedback (e.g., provides corrupt directional feedback, introduces fake objects, etc.) to the opponent. In still another embodiment, a user may choose to use another character's perspective (e.g., of a teammate or opponent with or without permission, etc.). For example, a user may use a teammate's virtual character's perspective to gain a greater awareness of threats ahead or in another location of the virtual environment.
According to yet another example embodiment, processing circuit 30 is configured to control the operation of elements 102 to provide a sense of at least one of a presence, a distance, and a direction of an object relative to the user of feedback device 100. The feedback may be based on at least one of a distance of an object (e.g., secondary object, another person, etc.) relative to the user (or primary object), a direction of the object relative to the user, a nature/threat level of the object, and a user response to previously-provided feedback. The feedback provided by elements 102 may include, but are not limited to, a vibration, a stroke or swipe, an acoustic stimulation, a visual stimulation, a temperature change, a moisture change, a lubrication, and/or an electrical stimulation. The vibration may be provided by a vibratory element. The stroke or swipe may be provided by a plurality of vibratory elements actuated in succession, simultaneously, and/or in a specific pattern (e.g., the vibratory elements are arranged in a linear pattern such that each may provide vibratory feedback to a user along the pattern, etc.). The temperature change may be provided by a heating/cooling element (e.g., a resistive heating element, a heating element that utilizes a chemical reaction, a fan, etc.). The moisture or lubrication may be provided by a nozzle attached to a fluid reservoir (e.g., a water tank, etc.) or a humidifying material or device. The electrical stimulation may be provided by a device configured to provide electrical impulses (e.g., electrical muscle stimulation, etc.).
In one embodiment, the feedback is derived from, modulated by, and/or accompanied by audio information. By way of example, using audio information, feedback device 100 may provide a user with feedback derived from the audio information indicating where a sound is coming from. By way of another example, in a situation where music within an electronic game changes, processing circuit 30 may modulate the feedback based on the music. For example, a change in the background music may indicate an intense or more difficult portion of the electronic game is occurring, where processing circuit 30 may adjust the feedback based on the situation. By way of yet another example, the feedback may be provided in the form of or accompanied by an audio output (e.g., audible feedback, from a speaker, etc.), as described above. The audio information may include a musical score, a tone, a notification, etc. In another embodiment, the feedback is accompanied by visual information supplied to the user of feedback system 10 or visual information is withdrawn from the user. By way of example, feedback device 100 may include a visual element, such as an LED light, configured to provide visual feedback. By way of another example, processing circuit 30 may provide a visual indication on display device 70 or remove the visual indication from display device 70. For example, processing circuit 30 may provide visual feedback in the form of a message (e.g., a warning, an update, etc.) or direction arrow (e.g., indicating a direction of an object, etc.) on display device 70.
In one embodiment, processing circuit 30 is configured to provide feedback to the user of feedback device 100 based on a feedback actuation function. The feedback actuation function may include a presence actuation function, a distance actuation function, and/or a direction actuation function. The presence actuation function is configured to provide a sense of a presence of an object (e.g. another person, a secondary object, within a proximity of the user or primary object, etc.). The sense of the presence may include a sense of a scale, an energy, a mass, a movement capability, a nature, and a threat level of the object, among other possibilities. The presence actuation function may provide a user or give the user the ability to provide a sense of a threat or friendliness. For example, a user may receive feedback from another person, such as a stroke along the back or a hugging sensation, to provide a sense of comfort. This may be implemented in situations such as a parent providing comfort to his/her premature baby that is isolated from physical contact or family members living apart from one another and being able to give a loved one a simulated hug, among other examples.
The distance actuation function is configured to provide a sense of a distance of an object relative to the user or primary object. The direction actuation function is configured to provide a sense of a direction of an object relative to the user or primary object. The relative priority of the presence actuation function, the distance actuation function, and the direction actuation function may vary responsive to the distance, the direction, and the nature of the object relative to the user or primary object. In some embodiments, the feedback actuation function is based on the relative position of elements 102 on the user of haptic feedback device 100, the relative position of the user, and/or the relative position of the object. By way of example, feedback may need to be provided in a desired location, however the position of elements 102 may not facilitate the application of feedback in the desired location. Therefore, the feedback actuation function may actuate various elements 102 around the desired location. For example, processing circuit 30 may actuate elements 102 in a circular pattern around the desired location to indicate the location in which feedback is desired to be provided.
The feedback actuation function may be a continuous function, a discrete function, a linear function, a non-linear function, or any combination thereof By way of example, the distance actuation function may increase an amplitude of the feedback linearly as an object (e.g., another person, a secondary object, etc.) gets closer to the user or primary object, or vice versa (e.g., inversely proportional to the distance, etc.). By way of another example, the distance actuation function may increase the amplitude of the feedback non-linearly (e.g., exponentially, quadratically, etc.) as an object (e.g., another person, a secondary object, etc.) gets closer to the user or primary object, or vice versa.
In one embodiment, processing circuit 30 is configured to modify the feedback actuation function responsive to a user response to previously-provided feedback (e.g., reduce, amplify, alter, etc.). The user response may include, but is not limited to, a body movement, a head movement, a temperature, a heart rate, a skin conductivity, a facial expression, a vocal expression, pupil dilation, brain waves, and/or a brain state. By way of example, processing circuit 30 may actuate various elements 102 as a user of feedback device 100 rotates his/her head. For example, processing circuit 30 may provide a vibration to a side of a user's head to indicate an object is to the user's side. As the user turns his/her head, the direction actuation function may modify which elements 102 provide feedback to the user such that the vibrations move as the user's head turns until the user's head is facing the indicated direction (e.g., the vibrations may move counter-clockwise as the user turn his/her head clockwise, etc.). The various functions disclosed herein may be embodied as instructions or programs implemented on or accessed by feedback system 10. In one embodiment, the instructions and/or programs are stored locally in memory (e.g., memory 38, etc.) of feedback system 10. In another embodiment, the instructions and/or programs are accessed via any suitable wired or wireless communication protocol to an external memory or via the Internet. Access to the Internet may provide for the ability to update the instructions and/or programs of feedback system 10 (e.g., periodically, when an update is released, etc.).
According to the example embodiment shown in FIGS. 1 and 6-8C, feedback system 10 (e.g., situational awareness system, etc.) is configured to provide feedback for real-world applications. For example, feedback system 10 may be used for driving, treatment for sight or hearing-impaired persons, aviation, sports, combat, etc.
Referring now to FIG. 6, area 200, usable in connection with feedback system 10, is shown according to one embodiment. As shown in FIG. 6, area 200 includes a ground surface 202 upon which a user, such as user P1 (e.g., an athlete, a motor vehicle operator, a military personnel, etc.), is moving. In some embodiments, user P1 is participating in an athletic event (e.g., a paintball game, football game, an automotive race, etc.) where opponents (e.g., other users, other vehicles, etc.), such as opponents O1, O2, and O3, or other obstacles (e.g., walls, posts, vehicles, etc.) are present.
In one embodiment, area 200 includes one or more external sensors 92 (e.g., remote sensors, etc.) configured to acquire external data (e.g., second data, etc.). External sensors 92 are positioned around or within area 200, and configured to acquire various data regarding area 200, the user P1, and/or opponents O1, O2, and O3. External sensors 92 may include any suitable sensors configured to detect the position, movement (e.g., velocity, acceleration, etc.), identity (e.g., team affiliation, etc.), etc. of the user P1 and/or opponents O1, O2, and O3. As discussed in further detail below, additional sensors may be worn by user P1 (e.g., as part of a head protection device, torso protection device, leg protection device, one or more head, wrist or ankle bands, as part of a team uniform, etc.) and used to acquire data regarding various users, objects, or a surrounding area.
Referring now to FIG. 7, user P1 is a paintball player. In other embodiments, user P may be a racecar driver, a football player, a soldier, or another person using feedback system 10. As shown in FIG. 7, user sensors 94 are configured to be worn by, carried by, or travel with a user such as user P1. User sensors 94 may be positioned at various locations about one or more pieces of equipment or clothing worn by user P1. In one embodiment, user sensors 94 are provided in or on headgear 104 (e.g., a helmet, a head protection device, etc.). In some embodiments, user sensors 94 are provided on one or more articles of clothing 108 or bands 106, such as a uniform, jersey, shirt, pants, or a head or wrist band, etc. In other embodiments, opponents O1, O2, and/or O3 wear at least one of headgear 104, bands 106, and clothing 108 including user sensor 94 and use feedback system 10.
User sensors 94 may be or include a wide variety of sensors configured to acquire various types of data regarding user P1 (e.g., user data, first data, etc.), area 200, opponents O1, O2, and O3 (e.g., second data, etc.), and the like. For example, in one embodiment user sensors 94 are configured to acquire user data regarding a user wearing user sensors 94. The user data may include a position of the user, an acceleration and/or velocity of the user, positions and/or orientations of various body parts of the user, and so on. In some embodiments, user sensors 94 are configured to acquire user data regarding other users or objects (e.g., in addition to or rather than the user wearing sensors 94). The user data may include a position of another user, an acceleration and/or velocity of the other user, positions and/or orientations of various body parts of the other user, an affiliation of the other user, and so on. In addition, various data may be obtained in absolute terms (e.g., position, velocity, acceleration) and transformed into relative terms for two or more users (e.g., by comparing absolute values of various users, etc.).
In one embodiment, user sensors 94 are or include an inertial sensing device, such as an accelerometer, a gyroscope, and the like. In other embodiments, user sensors 94 are or include an image capture device, such as a still image and/or video camera. In further embodiments, user sensors 94 include a GPS receiver. In addition to such passive sensors, user sensors 94 may in some embodiments be or include an active sensor, such as a lidar system, radar system, sonar system (e.g., an ultrasonic sonar or sensing system), etc.
In other embodiments, user sensors 94 are configured to provide data regarding team affiliations of various users. For example, user sensors 94 in some embodiments are or include a beacon, such as an RFID tag, that may be carried by each user. The RFID tags may provide team affiliation data, and may provide user-specific data, such as a user height, weight, etc. (e.g., through near field communication, etc.). In one embodiment, the beacons communicate with one another. In other embodiments, signals from the beacons are received by external sensors 92 to be provided to control system 20.
In one embodiment, user sensors 94 are configured to determine an orientation of a user's head (e.g., a direction in which the user is facing, a tilt of the head relative to the horizon, etc.). As such, user sensors 94 may be spaced about the user's head to form a sensor array configured to acquire positional data regarding the orientation of the user's head.
In some embodiments, feedback system 10 is implemented as part of a vehicle operator system, such that one or more user sensors 94 are provided as part of a vehicle. For example, a vehicle may include one or more user sensors 94 configured to provide sensor data to control system 20 regarding other vehicles or objects. Furthermore, the vehicle (e.g., a vehicle computer or control system, etc.) may be configured to provide additional data regarding operation of the vehicle, such as information regarding velocity, acceleration, braking conditions, and the like. A user (e.g., a motorcycle operator, a racecar driver, a bicycle rider, etc.) may wear a head protection device such as headgear 104 (e.g., helmet such as a football, baseball, or hockey helmet, a motorcycle or bicycle helmet, a soldier helmet, a ski helmet, etc.) configured to house additional user sensors 94 and/or portions of control system 20 and provide feedback. For example, feedback may be provided to a driver of a first vehicle to indicate that a driver of a second vehicle is in the blind spot of the driver of the first vehicle. As a result, the feedback may substantially reduce the likelihood of a collision between the two vehicles.
Referring back to FIG. 6, the various sensors (e.g., external sensors 92, user sensors 94, etc.) acquire data regarding user P1, opponents O1, O2, O3, and/or area 200 and provide the data to control system 20. Control system 20 is configured to control operation of feedback device 100 to provide haptic feedback to user P1 based on the data received from senor system 90 (e.g., external sensors 92, user sensors 94, etc.). For example, referring further to FIG. 6, user P1 is shown to be within area 200, along with opponents O1 and O2. Opponents O1 and O2 are in close proximity (e.g., pose a possible threat, etc.) to user P1, while opponent O3 is not within a close proximity (e.g., does not pose a threat, substantially far from user P1, not in play, etc.). As such, based on sensor data (e.g., head orientation, affiliation, position, movement, external data, user data, etc.) from sensor system 90, control system 20 is configured to provide feedback to user P1 via feedback device 100. In one embodiment, feedback device 100 provides the user with feedback such that the user has a heightened awareness of the opponents and/or threats outside of his/her field of view. For example, opponent O2 is not within the field of view of user P1 such that user P1 is unable to see opponent O2. In other embodiments, feedback device 100 further provides the user with feedback for opponents within the user's field of view to reinforce the intuitive understanding of what each vibration or other type of feedback (e.g., audible, visual, etc.) represents or to establish an affiliation of the person in the user's field of view. For example, opponent O1 is within the field of view of user P1 such that user P1 is able to see opponent O1.
Referring now to FIGS. 8A-8C, user P1, opponents O1 and O1, sensor system 90, and/or control system 20 may communicate with each other in a variety of ways, using any suitable wired and/or wireless communications protocols. User P1 generally includes one or more user sensors 94 and one or more feedback devices 100 (see, e.g., FIG. 7). In one embodiment, control system 20 is implemented as a remote system configured to communicate with one or more users of feedback system 10 (e.g., via corresponding feedback devices 100, etc.). For example, referring to FIG. 8A, user P1, opponent O1, and opponent O2 are configured to communicate user data to control system 20, which is in turn configured to receive external data from external sensors 92. Control system 20 is configured to provide feedback to each user based on at least one of user data and external data to increase the awareness of each user regarding threats around them (e.g., opponents, etc.).
In other embodiments, control system 20 is implemented into equipment worn, carried, or otherwise moving with the users of feedback system 10, such that the devices of user P1 and opponents O1 and O2 can communicate directly with one another. For example, referring to FIG. 8B, user sensors 94 are configured to acquire user data regarding user P1 and/or opponents O1 and O2. Based on the user data, control system 20 of the respective user (e.g., user P1, opponent O1, etc.) is configured to provide feedback to the user. In one embodiment, users with the same affiliation (e.g., same team, etc.) communicate with one another (e.g., regarding feedback received, etc.) such that a user may receive advanced notification of opponents/enemies near other users with the same affiliation. This example embodiment is able to be used in ad hoc environments (e.g., unfamiliar environments, hostile environments, environments without external sensors 92, etc.). For example, the configuration shown in FIG. 8B may be implemented with soldiers in hostile environments or for training purposes.
In further embodiments, user P1, opponent O1, and/or opponent O2 are configured to communicate user data to at least one of control system 20 and other users/opponents, which are in turn configured to receive external data from external sensors 92. For example, referring to FIG. 8C, control system 20 is configured to provide feedback to each user based on at least one of the user data and the external data to increase the awareness of each user regarding threats around them (e.g., opponents, etc.). In one embodiment, users with the same affiliation (e.g., same team, etc.) communicate with one another (e.g., regarding feedback received, etc.) such that a user may receive advanced notification of opponents/enemies near other users with the same affiliation.

For example, a color of a lit light 536 may indicate a team with which a user is associated (such as a red team, a blue team, or the like). As further examples, on-or-off condition or color of a light 536 may indicate condition of a user, whether the electronic system 10 is on or off, which haptic element 102 is actuated, or the like. A lamp control unit 538 is operatively coupled to the interface connection circuit 530. The lamp control unit 538 is any suitable electronic controller configured to receive and process output from the electronic system 10 (via the interface connection circuit 530) and generate signals accordingly for each of the lights 536 to be actuated. In some embodiments, the lamp control unit 538 may be a separate component from the haptic element control unit 532. In some other embodiments, the lamp control unit 538 may be implemented by the haptic element control unit 532. Lamp drivers 540 are operatively coupled between the lamp control unit 538 and the lights 536 (that is, each light 536 is operatively coupled to its own associated lamp driver 540). The lamp drivers 540 are suitable drivers that receive output from the lamp control unit 538 and generate electronic signals suitable for driving the lights 536.
