DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] Detailed Description The configurations described herein relate to the use of shape memory material based actuators in association with currently known or later developed chairs used for viewing visual content, such as gaming chairs, movie chairs, theater chairs, or any other similar seating structures. The chairs can be configured to move in synchronization with visual content presented to an occupant of the chair. The chairs can include a number of actuators operatively positioned relative to a seating portion of the chair. The actuators can include one or more shape memory material members. Selected actuators can be actuated to move the seating portion in a manner synchronized with the visual content.

[0008] Although detailed embodiments are disclosed herein, it should be understood that the disclosed embodiments are intended as examples only. Therefore, the specific structural and functional details disclosed herein should not be interpreted as limitations, but merely as a basis for the claims, and should be interpreted as a representative basis for teaching those skilled in the art to use the aspects herein in substantially any appropriately detailed structure. Furthermore, the terms and phrases used herein are not intended to be limiting, but rather to provide an understandable description of possible embodiments. Although various embodiments are shown in Figures 1-11, the embodiments are not limited to the illustrated structures or applications.

[0009] It will be understood that for brevity and clarity of description, where necessary, reference numerals have been repeated among the different figures to indicate corresponding or similar elements. Furthermore, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those skilled in the art that the embodiments described herein may be practiced without these specific details.

[0010] With reference to FIG. 1 , an example of a chair 100 is shown. Chair 100 may be any type of seat now known or later developed. Chair 100 may have any suitable configuration. For example, chair 100 may include a back portion 102 and a seat portion 104. In some configurations, chair 100 may include a headrest 106 and / or armrests 108. In some configurations, chair 100 may be an office chair, a gaming chair, a cinema chair, a recliner, or any other type of seat or chair now known or later developed.

[0011] The chair 100 may include a base portion 110 located below the seat portion 104. The seat portion 104 may include a cushion. The base portion 110 may include an upper platform 112 and a lower platform 114. In an inoperative state, the upper platform 112 and the lower platform 114 may be substantially parallel to one another.

[0012] In some configurations, the base portion 110 can include one or more sidewalls 116. The sidewalls 116 may be operably connected to the lower platform 114. In some configurations, the sidewalls 116 may be a rigid structure. In such cases, the sidewalls 116 may not be attached to the upper platform 112. When one or more of the actuators 200 are actuated, a portion of the upper platform 112 may move away from the sidewalls 116. In some configurations, the sidewalls 116 may be configured to expand and contract, such as in a bellows-like configuration. In such cases, the sidewalls 116 may be operably connected to the upper platform 112. Thus, when one or more of the actuators 200 are actuated, the upper platform 112 may remain connected to the sidewalls 116.

[0013] 2 is a view of the chair 100 with the base portion 110 cut away. A plurality of actuators 200 may be located within the base portion 110. The plurality of actuators 200 may be operably positioned between the upper platform 112 and the lower platform 114. When unactuated, the upper platform 112 and the lower platform 114 may be substantially parallel to one another. It will be understood that the terms "upper" and "lower" are used for convenience to refer to the relative positions of the structures when used in their intended operating positions, and that these terms are not intended to be limiting. The actuators 200 may be operably connected to one or both of the upper platform 112 and the lower platform 114.

[0014] The lower platform 114 may be substantially fixed. As a result, activation and deactivation of the actuator 200 does not essentially affect the orientation or position of the lower platform 114.

[0015] On the other hand, the upper platform 112 may be configured to be movable in response to activation or deactivation of the actuator 200. As a result, the actuator 200 may cause movement of the seating portion 104 or the remainder of the chair 100 located above the upper platform 112. The seating portion 104 may be supported by the upper platform 112.

[0016] The plurality of actuators 200 may be arranged in any of a number of ways. Several example arrangements are shown in Figures 3-5. With reference to Figure 3, an example of a first arrangement 300 of the plurality of actuators 200 is shown. In this example, the actuators 200 may be arranged in a substantially rectangular pattern. Each actuator 200 may be oriented at substantially 90 degrees relative to adjacent actuators 200.

[0017] 4, an example of a second arrangement 400 of the plurality of actuators 200 is shown. In this example, the plurality of actuators 200 may be arranged in an offset substantially parallel pattern. As shown, there may be two groups of actuators 200. In each group, the actuators 200 may be offset from one another. Also, the actuators 200 may be substantially parallel to one another.

[0018] 5 is an example of a third arrangement 500 of a plurality of actuators 200. In this example, the actuators 200 may be arranged in a radial pattern around a central point or region. The actuators 200 may be substantially equally spaced, or one or more of the actuators 200 may be non-equally spaced from the other actuators 200.

[0019] While the above examples show various configurations in which there are four actuators, it will be appreciated that the configurations described herein are not limited to the presence of four actuators, and indeed there may be more than four actuators, or fewer than three actuators.

[0020] Figures 7 and 8 show an example of the actuator 200. Figure 7 shows an example of the actuator 200 in an unactuated state, and Figure 8 shows an example of the actuator 200 in an actuated state.

[0021] The actuator 200 may include a first end cap 210 and a second end cap 220. The first end cap 210 and the second end cap 220 may be spaced apart. The first end cap 210 and the second end cap 220 may face each other.

[0022] The first end cap 210 and the second end cap 220 can have any suitable size, shape, and / or configuration. In one or more configurations, the first end cap 210 and the second end cap 220 can be substantially mirror images of one another. In one or more configurations, the first end cap 210 can have three prongs, including an upper prong 212, a middle prong 214, and a lower prong 216. Similarly, the second end cap 220 can have three prongs, including an upper prong 222, a middle prong 224, and a lower prong 226.

[0023] The first end cap 210 and the second end cap 220 may be made of any suitable material. The first end cap 210 and the second end cap 220 may be of substantially rigid construction. In some configurations, the upper prongs 212, 222 and the lower prongs 216, 226 of the first and second end caps 210, 220 may be flexible to accommodate changes in the actuator 200 when actuated and unactuated. The first and second end caps 210, 220 may be oriented such that the central prong 214 of the first end cap 210 is substantially aligned with the central prong 224 of the second end cap 220.

[0024] The actuator 200 can include a first outer member 240. The first outer member 240 can have a curved shape. The first outer member 240 can have a convex side 242 and a concave side 244. In some configurations, the first outer member 240 can be made of a single piece of material. In other configurations, the first outer member 240 can be made of multiple pieces of material. In some configurations, the first outer member 240 can be made of multiple layers. The first end cap 210 and the second end cap 220 can be made of any suitable material. In some configurations, the first outer member 240 can be made flexible to accommodate changes in the actuator 200 when actuated and unactuated.

[0025] The first outer member 240 can include one or more protrusions 246. The protrusions 246 can be used to properly position another structure over the plurality of actuators 200. In some configurations, the protrusions 246 can be substantially centrally located on the convex side 242 of the first outer member 240. In some configurations, the protrusions 246 can be formed separately and operably connected to the convex side 242 of the first outer member 240. Any suitable manner of operable connection can be provided, such as one or more fasteners, one or more adhesives, one or more welds, one or more brazes, one or more forms of mechanical engagement, or any combination thereof. In other configurations, the protrusions 246 and the first outer member 240 can be formed together as a unitary structure.

[0026] The first outer member 240 may be operably connected to the first end cap 210 and the second end cap 220. For example, the first outer member 240 may be operably connected to the upper prong 212 of the first end cap 210 and the upper prong 222 of the second end cap 220. Any suitable manner of operable connection may be provided, such as one or more fasteners, one or more adhesives, one or more welds, one or more brazes, one or more forms of mechanical engagement, or any combination thereof. In some configurations, one or more portions of the first outer member 240, such as the ends, may be operably connected to the central prong 214 of the first end cap 210 and the central prong 224 of the second end cap 220.

[0027] The actuator 200 can include a second outer member 250. The second outer member 250 can have a curved shape. The second outer member 250 can have a convex side 252 and a concave side 254. In some configurations, the second outer member 250 can be made of a single piece of material. In other configurations, the second outer member 250 can be made of multiple pieces of material. In some configurations, the second outer member 250 can be made of multiple layers. The first end cap 210 and the second end cap 220 can be made of any suitable material. In some configurations, the second outer member 250 can be made flexible to accommodate changes in the actuator 200 when actuated and unactuated.

[0028] The actuator 200 can include a base 260. The base 260 can provide stability to the actuator 200. In some configurations, the base 260 can be operably connected to the convex side 252 of the second outer member 250. Any suitable manner of operable connection can be provided, such as one or more fasteners, one or more adhesives, one or more welds, one or more brazes, one or more forms of mechanical engagement, or any combination thereof. In other configurations, the base 260 and the second outer member 250 can be formed together as a unitary structure. The base 260 can have any suitable size, shape, and / or configuration. The base 260 can be a substantially flat structure. In one or more configurations, the base 260 can be substantially rectangular. The base 260 can be made of any suitable material. The base 260 can be made of the same material as the second outer member 250, or the base 260 can be made of a different material.

[0029] The actuator 200 can include one or more ribs 256. The ribs 256 can prevent the first outer member 240 from collapsing. In some configurations, the ribs 256 can be operably connected to the concave side 254 of the second outer member 250. Any suitable manner of operable connection can be provided, such as one or more fasteners, one or more adhesives, one or more welds, one or more brazes, one or more forms of mechanical engagement, or any combination thereof. In other configurations, the ribs 256 and the second outer member 250 can be formed together as a unitary structure. The ribs 256 can have any suitable size, shape, and / or configuration. In one or more configurations, the ribs 256 can be substantially rectangular. The ribs 256 can be made of any suitable material. The ribs 256 can be made of the same material as the second outer member 250, or the ribs 256 can be made of a different material.

[0030] The second outer member 250 may be operably connected to the first end cap 210 and the second end cap 220. For example, the second outer member 250 may be operably connected to the lower prong 216 of the first end cap 210 and the lower prong 226 of the second end cap 220. Any suitable manner of operable connection may be provided, such as one or more fasteners, one or more adhesives, one or more welds, one or more brazes, one or more forms of mechanical engagement, or any combination thereof. In some configurations, one or more portions of the second outer member 250, such as the ends, may be operably connected to the central prong 214 of the first end cap 210 and the central prong 224 of the second end cap 220.

[0031] The first outer member 240 and the second outer member 250 may be constructed of or may include a substantially flexible material. The first outer member 240 and the second outer member 250 may be reversibly deformable, such that the first outer member 240 and the second outer member 250 do not suffer damage upon deformation. Damage may include cracking, breaking, shattering, or other forms of inelastic deformation. In some embodiments, the flexible material is a flexible polymer. Specific examples of flexible polymers that may be used in various embodiments include rubber (natural rubber, styrene-butadiene, polybutadiene, neoprene, ethylene-propylene, butyl, nitrile, silicone, etc.), polycarbonate, acrylic, polyester, polyethylene, polypropylene, nylon, polyvinyl chloride, polystyrene, elastomers, polyolefins, and other flexible polymers known to those skilled in the art. In some embodiments, the flexible material can be exposed to a degree of stretch selected within a range of about 1% to about 1300%, such as about 10% to about 1300% or about 100% to about 1300%, without mechanical failure (e.g., tearing, cracking, or inelastic deformation). In further embodiments, the flexible material can be deformed to a radius of curvature selected within a range of 100 micrometers (μm) to 3 meters (m) without mechanical failure.

[0032] The first outer member 240 and the second outer member 250 may be oriented with their concave sides 244, 254 facing one another. The first outer member 240 and the second outer member 250 may define a cavity 270.

[0033] The actuator 200 may include one or more shape memory material members 280. The shape memory material members 280 may be operably connected to the first end cap 210 and the second end cap 220. More specifically, the shape memory material members 280 may be operably connected to the central prongs 214 and 224 of the first end cap 210 and the second end cap 220. Any suitable manner of operative connection may be provided, such as one or more fasteners, one or more adhesives, one or more welds, one or more brazes, one or more forms of mechanical engagement, or any combination thereof. The shape memory material members 280 may be located within the cavity 270.

[0034] In some configurations, there can be a single shape memory material member 280. In such cases, the shape memory material member 280 can extend, for example, straight across the cavity from the first end cap 210 and the second end cap 220. In another example, the shape memory material member 280 can extend in a zigzag or serpentine pattern between the first end cap 210 and the second end cap 220.

[0035] In some configurations, there can be multiple shape memory material members 280. In such cases, the shape memory material members 280 can be distributed, positioned, and / or oriented in any suitable manner. For example, the shape memory material members 280 can extend substantially parallel to one another. In other configurations, one or more of the shape memory material members 280 can extend non-parallel to the other shape memory material members 280. In some cases, some of the multiple shape memory material members 280 may cross one another.

[0036] The phrase "shape memory material" includes materials that change shape when an actuation input is applied to the shape memory material, and when the actuation input is discontinued, the material substantially returns to its original shape. Examples of shape memory materials include shape memory alloys (SMA) and shape memory polymers (SMP).

[0037] In one or more configurations, the shape memory material member 280 may be a shape memory material wire. As an example, the shape memory material member 280 may be a shape memory alloy wire. Thus, when an actuation input (i.e., heat) is provided to the shape memory alloy wire, the wire can contract. The shape memory alloy wire can be heated in any suitable manner now known or later developed. For example, the shape memory alloy wire can be heated by Joule effect by passing an electric current through the wire. In some cases, a configuration for cooling the shape memory alloy wire can be provided to facilitate the return of the wire to the non-actuated configuration, if necessary.

[0038] The wire can have any suitable characteristics. For example, the wire can be a high temperature wire having an austenite finish temperature of about 80 degrees Celsius to about 110 degrees Celsius. The wire can have any suitable diameter. For example, the wire can be about 0.2 millimeters (mm) to about 0.7 mm, about 0.3 mm to about 0.5 mm, or about 0.375 mm to about 0.5 mm in diameter. In some configurations, the wire can have a stiffness of up to about 70 gigapascals. The tensile strength of the SMA wire can be about 250 MPA to about 400 MPa. The wire can be configured to provide an initial moment of about 300 to about 600 N·mm, or greater than about 500 N·mm, where the unit of newton millimeter (N·mm) is the unit of torque (also called moment) in the SI system. One newton meter is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm one meter in length. In various embodiments, the wire can be configured to change phase to transition the shape memory material member 280 from the unactuated position to the actuated position in about 3 seconds or less, about 2 seconds or less, about 1 second or less, or about 0.5 seconds or less.

[0039] The wire can be made of any suitable shape memory material now known or later developed. Different materials can be used to achieve different balances, characteristics, properties, and / or qualities. By way of example, the SMA wire can include nickel-titanium (Ni-Ti, or Nitinol). One example of a nickel-titanium shape memory alloy is FLEXINOL, available from Dynaolloy, Inc., Irvine, Calif. By way of further example, the SMA wire can be made of Cu-Al-Ni, Fe-Mn-Si, or Cu-Zn-Al.

[0040] The SMA wire is then heated to a temperature, e.g., SMAThe SMA wire can be configured to increase or decrease in length upon a phase change by being heated to a temperature of 1000° C. Exploiting the unique properties of the SMA wire can be achieved by using heat, for example, by passing an electric current through the SMA wire to cause heat to be generated by electrical resistance, to change the phase or crystal structure transformation (i.e., twinned martensite, non-twinned martensite, and austenite) resulting in an elongation or shortening of the SMA wire. In some embodiments, upon a phase change, the SMA wire changes to a temperature of 1000° C. SMA From temperatures lower than T SMA When heated to temperatures above 100° C., the cellulose fiber may undergo a reduction in length of from about 2 to about 8%, or from about 3 to about 6%, and in certain embodiments, about 3.5%.

[0041] Other active materials may be used in conjunction with the configurations described herein. For example, other shape memory materials may be used. Shape memory materials, a class of active materials sometimes referred to as smart materials, include materials or compositions that have the ability to remember their original shape, which can later be recalled by application of an external stimulus, such as an actuation signal.

[0042] Although the shape memory material member 280 is described as being a wire in some embodiments, it will be understood that the shape memory material member 280 is not limited to being a wire. Indeed, it is envisioned that suitable shape memory materials may be used in a variety of other forms, such as sheets, plates, panels, strips, cables, tubes, or combinations thereof. In some configurations, the single shape memory material member 280 may include an insulating coating.

[0043] The actuator 200 may include a first dimension 290 and a second dimension 295. The first dimension 290 may represent a width of the actuator 200, and the second dimension 205 may represent a height of the actuator 200. The first dimension 290 and the second dimension 295 may be substantially perpendicular to one another.

[0044] 8 is an example of the actuator 200 in an actuated state. When an actuation input (e.g., electrical energy) is provided to the shape memory material member 280, the shape memory material member 280 can contract. This contraction causes the shape memory material member 280 to pull the first end cap 210 and the second end cap 220 toward each other in a direction corresponding to the first dimension 290.

[0045] This allows the ends of the first outer member 240 to be drawn toward one another in a direction corresponding to the first dimension 290, and the ends of the second outer member 250 to be drawn toward one another in a direction corresponding to the first dimension 290. As a result, the first outer member 240 and the second outer member 250 can be flexed outwardly and away from one another in a direction corresponding to the second dimension 295. It will be appreciated that the first dimension 290 (i.e., width) of the actuator 200 can be decreased and the second dimension 295 (i.e., height) of the actuator 200 can be increased.

[0046] It will be understood that the actuator 200 shown in Figures 7 and 8 is just one example of an actuator that can be used in conjunction with the configurations described herein. Other actuator configurations are possible. Further non-limiting examples of actuators having shape memory material members are described in U.S. Patent No. 10,960,793, U.S. Patent No. 11,285,844, and U.S. Patent Application Publication No. 2020 / 0298732, which are incorporated by reference in their entireties.

[0047] 6 is a diagram of a portion of chair 100 showing upper platform 112 resting on a number of actuators 200. As described above, upper platform 112 may be supported by actuators 200. In some configurations, upper platform 112 may be a plate-like structure. Upper platform 112 may be made of any suitable material, such as, for example, metal, alloy, plastic, polymer, acrylic, or wood, to name a few possibilities. Upper platform 112 may have any suitable size, shape, and / or configuration. In one or more configurations, upper platform 112 may be substantially rectangular.

[0048] The upper platform 112 may be operatively connected to a number of actuators 200. Any suitable form of operative connection may be provided. For example, the upper platform 112 may include a number of openings 113. Each of the openings 113 may receive a respective one of the protrusions 246 on the actuator 200. In this manner, the upper platform 112 may be properly positioned on the actuator 200. It will be appreciated that the upper platform 112 may be substantially horizontal when the actuator 200 is not actuated. When the actuator 200 is actuated, the upper platform 112 may be non-horizontal. When the actuator 200 is actuated, the protrusions 246 may remain in the openings 113 of the upper platform 112.

[0049] Alternatively, or in addition, other forms of operative connection between the upper platform 112 and the actuator 200 may be provided. For example, the upper platform 112 may be operatively connected to the actuator 200 by one or more fasteners, one or more adhesives, one or more forms of mechanical engagement, or any combination thereof.

[0050] FIG. 11 illustrates an example of a system 1100. The system 1100 can include various elements. Some of the possible elements of the system 1100 are illustrated in FIG. 11 and described herein.

The processor 1110 may be implemented with one or more general-purpose processors and / or one or more special-purpose processors. Examples of suitable processors include microprocessors, microcontrollers, DSP processors, and other circuits capable of executing software. Further examples of suitable processors include, but are not limited to, central processing units (CPUs), array processors, vector processors, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), application specific integrated circuits (ASICs), programmable logic circuits, and controllers. The processor 1110 may include at least one hardware circuit (e.g., an integrated circuit) configured to execute instructions contained in a program code. In configurations where multiple processors 1110 are present, such processors may operate independently of one another, or one or more processors may operate in combination with one another.

[0053] The system 1100 may include one or more data stores 1120 for storing one or more types of data. The data stores 1120 may include volatile and / or non-volatile memory. Examples of suitable data stores 1120 include RAM (Random Access Memory), flash memory, ROM (Read Only Memory), PROM (Programmable Read-Only Memory), EPROM (Erasable Programmable Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage medium, or any combination thereof. The data stores 1120 may be components of the processor 1110, or the data stores 1120 may be operably connected to the processor 1110 for use by the processor 1110. As used throughout this specification, the term "operably connected" can include direct or indirect connections, including connections without direct physical contact.

[0054] In some configurations, the data store 1120 can include one or more actuation profiles 1122. An actuation profile 1122 can be a predetermined pattern of activation and deactivation of one or more of the actuators 200 to achieve a desired movement of the chair 100. Examples of actuation profiles 1122 can include tilt forward, tilt back, tilt right, tilt left, rock forward, rock left, rock up, down, vibrate, or any combination thereof. An actuation profile 1122 can be for any time period. In some cases, an actuation profile 1122 can be for a moment in time.

[0055] The system 1100 can use the actuation profile 1122 to actuate the actuators 200 without having to determine in real time which actuators 200 will achieve the desired movement of the chair 100. It should be noted that the actuation profile 1122 can take into account one or more characteristics of the occupant of the chair 100. For example, the actuation and de-actuation of the actuators 200 can be varied based on one or more characteristics of the occupant of the chair 100, such as the weight of the occupant of the chair. If the person is heavier than a predetermined base weight or weight range, the actuation and de-actuation of the actuators 200 can be performed with a greater degree of force. In contrast, if the occupant of the chair is lighter than a predetermined weight level or weight range, the actuation and de-actuation of the actuators 200 can be performed with a lesser degree of force.

[0056] The system 1100 can include one or more sensors 1130. A "sensor" means any device, component, and / or system that can detect, determine, evaluate, monitor, measure, quantify, obtain, and / or sense something. One or more sensors can detect, determine, evaluate, monitor, measure, quantify, obtain, and / or sense in real time. As used herein, the term "real time" refers to a level of processing responsiveness that a user or system perceives as immediate enough to make a particular process or decision, or that allows a processor to keep up with some external process.

[0057] In configurations in which the system 1100 includes multiple sensors 1130, the sensors may operate independently of one another. Alternatively, two or more of the sensors may operate in combination with one another. In such cases, the two or more sensors may form a sensor network. The sensors 1130 may be operatively connected to the processor 1110, the data store 1120, and / or other elements of the system 1100 (including any of the elements shown in FIG. 1).

[0058] The sensors 1130 may include any suitable type of sensor. Various examples of different types of sensors are described herein. However, it will be understood that embodiments are not limited to the particular sensors described.

[0059] The sensors 1130 can include one or more chair occupant sensors 1132. In some configurations, the chair occupant sensors 1132 can include a weight sensor. The weight sensor can be any suitable sensor now known or later developed.

[0060] In some configurations, the chair occupant sensor 1132 may include one or more gaze sensors. The gaze sensor may be any suitable sensor currently known or later developed. In one or more configurations, the gaze sensor may include one or more cameras, one or more eye sensors, one or more head sensors, one or more face sensors, one or more eye movement sensors, one or more gaze tracking sensors, one or more eye position sensors, one or more eye direction sensors, one or more head movement sensors, one or more head tracking sensors, one or more head position sensors, one or more head direction sensors, and / or one or more gaze tracking sensors, to name a few possibilities. The gaze sensor and / or the processor 1110 may be configured to determine the gaze of the chair occupant, e.g., the direction in which the chair occupant is looking. In some configurations, the gaze sensor may be incorporated into the display 1165 and / or the device in which the display 1165 is incorporated. In some configurations, the gaze sensor may include optical components that can be moved (e.g., rotated and / or translated) to identify eye angle, head angle, eye position, head position, and / or eyelid position.

[0061] As mentioned above, the system 1100 can include one or more power sources 1140. The power source 1140 can be any power source capable of and / or configured to operate the shape memory material member 280 of the actuator 200. For example, the power source 1140 can include one or more batteries, one or more fuel cells, one or more generators, one or more alternators, one or more solar cells, and combinations thereof.

[0062] The system 1100 can include one or more input interfaces 1150. An "input interface" includes any device, component, system, element, or arrangement, or grouping thereof, that allows information / data to be input into a machine. The input interface 1150 can receive input from a chair occupant. Any suitable input interface 1150 can be used, such as, for example, a keypad, a display, a touch screen, a multi-touch screen, a button, a joystick, a mouse, a trackball, a microphone, and / or combinations thereof.

[0063] The system 1100 can include one or more output interfaces 1155. An "output interface" includes any device, component, system, element, or arrangement, or grouping thereof, that allows for information / data to be presented to a chair occupant. The output interface 1155 can present information / data to a chair occupant. The output interface 1155 can include a display, earphones, and / or speakers. Some components of the system 1100 can function as both components of the input interface 1150 and components of the output interface 1155.

[0064] The system 1100 may include one or more displays 1165. The display 1165 may be any suitable type of display now known or later developed. The display 1165 may be configured to present visual content thereon. In some configurations, the display may be a monitor, a television, a laptop, a tablet computer, a smartphone, or other device including a display. In some configurations, the display 1165 may be formed by a projector that projects visual content onto a surface. In some configurations, the display 1165 may be part of a head-mounted display. As an example, the head-mounted display may be an extended reality (XR) headset. The XR headset may be any type of XR headset now known or later developed. Examples of XR headsets include augmented reality (AR), mixed reality (MR), and virtual reality (VR) headsets.

[0065] The system 1100 may include one or more visual content devices 1160. The visual content device 1160 may be any suitable device capable of presenting or causing visual content to be presented. The visual content device 1160 may be any type of visual content device now known or later developed. In some configurations, the visual content device 1160 may be a separate device operably connected to a display 1165. Non-limiting examples of such visual content devices include a gaming system, a Blu-ray player, a DVD player, an online or cloud streaming service, or a plug-and-play device, to name a few possibilities. In some configurations, the visual content device 1160 and the display 1165 may be integrated into the same device, such as a laptop.

[0066] The visual content presented by the visual content device(s) 1160 may be interactive, such as in a video game. One or more input devices may be operatively connected to the visual content device(s) 1160 to enable interaction with the visual content for a user. Examples of input devices may include any type of joystick, button, keyboard, keypad, switch, pedal, foot pedal, steering wheel, voice recognition, gesture recognition, motion recognition, or eye tracking now known or later developed. The input device may include any of the input interfaces 1150 described above. In such cases, the visual content device(s) 1160 may be responsive to input from a player or content viewer provided by the input device. In some cases, the visual content presented by the visual content device(s) 1160 may not be interactive, such as a movie. In such cases, the user may not be able to provide input to affect motion, perspective, and / or action in the visual content. However, basic visual controls (e.g., on / off, color, brightness, contrast, sharpness, tint, etc.) may be available to the user. In some cases, the visual content device 1160 can be configured to send a signal to one or more elements of the system 1100 (eg, the content analysis module 1170).

[0067] The system 1100 may include one or more modules, at least some of which are described herein. The modules may be implemented as computer-readable program code that, when executed by a processor, performs one or more of the various processes described herein. One or more of the modules may be components of the processor 1110, or one or more of the modules may execute on and / or be distributed among other processing systems to which the processor 1110 is operably connected. The modules may include instructions (e.g., program logic) executable by one or more processors 1110. Alternatively, or in addition, one or more data stores 1120 may include such instructions.

[0068] In one or more configurations, the modules described herein may include artificial or computational intelligence elements, such as neural networks, fuzzy logic, or other machine learning algorithms. Additionally, in one or more configurations, the modules may be distributed across multiple modules. In one or more configurations, two or more of the modules described herein may be combined into a single module.

[0069] The system 1100 may include one or more content analysis modules 1170. The content analysis module 1170 may be configured to receive visual content, signals, information, and / or data from the visual content device 1160. The content analysis module 1170 may be configured to analyze the visual content, signals, information, and / or data received from the visual content device 1160. In particular, the content analysis module 1170 may be configured to analyze the received visual content, signals, information, and / or data to identify motion within the visual content. The content analysis module 1170 may do this in any suitable manner now known or later developed. The content analysis module 1170 may incorporate any type of ride simulator or motion simulator technology now known or later developed.

[0070] For example, the content analysis module 1170 may be configured to analyze the motion of the visual content as a whole or based on the motion of one or more objects or items within the visual content. In some configurations, the content analysis module 1170 may be configured to analyze signals, information, or data associated with the visual content representing motion. The content analysis module 1170 may include any suitable hardware and / or software for receiving and processing signals from the visual content device 1160.

[0071] The content analysis module 1170 can be configured to determine a corresponding chair motion. Such a determination can be performed in real time based on the visual content presented on the display 1165. The corresponding chair motion can be a motion of the seat portion 104 or the remaining portion of the chair 100 located above the upper platform 112. The corresponding chair motion can be synchronized with at least a portion of the visual content. For example, if the content analysis module 1170 determines that the visual content includes a motion corresponding to the chair 100 leaning to the right. As another example, if the content analysis module 1170 determines that the visual content includes movement on uneven ground or train tracks, the content analysis module 1170 can determine that a vibration motion of the chair 100 is the corresponding chair motion.

[0072] The content analysis module 1170 can be configured to take into account the viewpoint of the visual content presented on the display 1165. For example, the content analysis module 1170 can evaluate whether the visual content is presented in a point of view (POV) manner. In such a case, the content analysis module 1170 can determine a corresponding movement that aligns with the movement presented on the display 1165. The content analysis module 1170 can evaluate whether the visual content is presented from some other viewpoint. In some cases, the corresponding chair movement may not necessarily align (e.g., in the same direction or on the same side) with the movement presented on the display 1165. The content analysis module 1170 can be configured to take into account human physiological processes and responses to movement.

[0073] The system 1100 may include one or more chair control modules 1180. The chair control module 1180 may be configured to receive signals, data, information, and / or other inputs from the content analysis module 1170. The chair control module 1180 may be configured to analyze these signals, data, information, and / or other inputs. The chair control module 1180 may be configured to select one or more actuators of the plurality of actuators 200 to be activated or deactivated to achieve a corresponding chair movement. In some configurations, the chair control module 1180 may be configured to select an appropriate one of the actuation profiles 1122 in the data store 1120 to achieve a corresponding chair movement. Alternatively or additionally, the chair control module 1180 may be configured to detect a user input (e.g., a command) provided to the input interface 1150.

[0074] The chair control module 1180 can activate or deactivate one or more selected actuators by activating or deactivating the respective shape memory material members 280 associated with the selected actuators 200. As used herein, "cause" or "causing" means to directly or indirectly configure, force, direct, command, order, and / or enable an event or action to occur or at least render such an event or action possible. The chair control module 1180 can selectively provide actuation inputs to the actuators 200, and more specifically to the shape memory material members 280 associated with the selected actuators 200. The chair control module 1180 can selectively allow or prevent the flow of electrical energy from the power source 1140. The chair control module 1180 can be configured to send control signals or commands to the shape memory material members 280 via the communication network 1190.

[0075] The chair control module 1180 can selectively activate or deactivate the shape memory material member 280 at a time that substantially coincides with the visual content. For example, if the visual content is a car racing game, the chair control module 1180 can selectively activate or deactivate the shape memory material member 280 to coincide with in-game events, such as the turning of the car.

[0076] The actuators 200 can be operatively positioned to cause movement of the chair 100 or any portion thereof. In some configurations, the actuators 200 can be responsive to signals received from the visual content device 1160, from an input device operatively connected to the visual content device 1160, and / or provided on the input interface 1150. The actuators 200 can expand and contract in an order or manner that supports a desired simulated movement presented in the visual content during, for example, a game play or movie, or otherwise requested by an occupant of the chair. The actuators 200 can provide various types of movement, including, but not limited to, upward and downward movement, forward and backward tilt, and / or side-to-side tilt. In some configurations, the actuators 200 can be configured to provide other movement, including linear forward and backward movement, linear side-to-side movement, and / or rotation about a vertical axis. In some configurations, the actuators 200 can be configured to provide six degrees of freedom (e.g., surge, sway, heave, roll, pitch, and yaw movement). Additionally, chair 100 can be configured to provide other haptic motions, such as vibration, rocking, pulsation, and the like.

[0077] The various elements of the system 1100 may be communicatively coupled to one another or to one or more other elements via one or more communications networks 1190. As used herein, the term "communicatively coupled" may include a direct or indirect connection via a communications channel, bus, path, or another component or system. A "communications network" refers to one or more components designed to transmit and / or receive information between one source and another. The data store 1120 and / or one or more other elements of the system 1100 may include and / or execute appropriate communications software that enables the various elements to communicate with one another via the communications network to perform the functions disclosed herein.

[0078] The one or more communications networks 1190 may be implemented as or may include, but are not limited to, a wide area network (WAN), a local area network (LAN), a Public Switched Telephone Network (PSTN), a wireless network, a mobile network, a Virtual Private Network (VPN), the Internet, a hardwired communications bus, and / or one or more intranets. Additionally, the communications network may be implemented as or may include one or more wireless networks, whether short-range (e.g., Bluetooth or a local wireless network built using one of the IEEE 802 wireless communication protocols, e.g., 802.11a / b / g / i, 802.15, 802.16, 802.20, Wi-Fi Protected Access (WPA), or WPA2) or long-range (e.g., mobile, cellular, and / or satellite-based wireless networks; GSM, TDMA, CDMA, WCDMA networks, etc.). The communications network may include wired and / or wireless communications links, and may include any combination of the above networks and / or other types of networks.

[0079] Having described various possible systems, devices, elements, and / or components for the chair 100 and the system 1100, an example of a method for moving a portion of a chair in synchronization with visual content will now be described. While the described methods may be applicable to the configurations described above, it will be understood that the methods may be performed in other suitable systems and configurations. Furthermore, the methods may include other steps not shown here, and indeed the methods are not limited to including all steps shown. The blocks shown here as part of the methods are not limited to a particular chronological order. Indeed, some of the blocks may be performed in a different order than shown, and / or at least some of the blocks shown may occur simultaneously.

[0080] 10, an example of a method 1000 is shown. At block 1010, visual content may be analyzed to determine a corresponding chair movement. The corresponding chair movement may be synchronized with at least a portion of the visual content. The analysis may be performed by the content analysis module 1170 and / or the processor 1110.

[0081] The analysis of the visual content may be performed continuously, periodically, or at any suitable time. If the visual content does not include a corresponding chair movement, method 1000 may return to block 1010 or some other block. If a corresponding chair movement is determined, method 1000 may continue to block 1020.

[0082] At block 1020, one or more of the multiple actuators may be selected to achieve a corresponding chair movement. Such selection may be performed by the chair control module 1180 and / or the processor 1110. The method may continue to block 1030.

[0083] In block 1030, the selected actuator may be actuated. For example, an actuation input may be provided to the selected actuator. As a result, the selected actuator may be actuated, thereby causing the chair to move according to a corresponding chair motion. Providing the actuation input may be performed by the chair control module 1180 and / or the processor 1110. For example, the chair control module 1180 and / or the processor 1110 may cause or enable a flow of electrical energy from the power source 1140 to the shape memory material member of the selected actuator.

[0084] The method 1000 may end, or the method 1000 may return to block 1010 or some other block.

[0085] A non-limiting example of the operation of the arrangement described herein will now be provided with reference to Figures 2 and 9. Figure 2 shows an example of a chair in an unactuated state, and Figure 9 shows an example of a chair in an actuated state. For the sake of clarity, no human is shown in these figures, although typically a human would be seated in the chair. For purposes of this example, the actuators may be arranged in a substantially rectangular arrangement, such as the arrangement shown in Figure 3.

[0086] The chair occupant may be playing a video game. The video game may be in the nature of a flight simulator presented from the player's point of view. When a human plays the game, the player may manipulate the aircraft to pitch to the left. As a result, in the game, the aircraft may pitch to the left and a corresponding view of the display shows such a movement. Such a movement during game play may be detected by a content analysis module and / or processor. As a result, the content analysis module and / or processor may determine that there should be a corresponding chair movement to synchronize with the displayed visual content.

[0087] The content analysis module 1170 and / or the processor 1110 may select an appropriate actuator 200 to achieve the corresponding chair movement. In this case, the content analysis module 1170 and / or the processor 1110 may select the actuator 201 to be actuated.

[0088] The content analysis module 1170 can inform the chair control module 1180 of the selected actuator 201. The chair control module 1180 can cause the provision of an actuation input to the selected actuator 201. Here, the chair control module 1180 can enable the supply of electrical energy from the power source 1140 to the shape memory material member 280 of the selected actuator 201. As a result, the actuator 201 can be transformed into an actuated configuration as shown in FIG. 9 (see also FIG. 8). The second dimension 295 corresponding to the height of the actuator 201 becomes larger than the height of the other actuators 200. This can cause the chair 100 to tilt to the left as shown in FIG. 9. The chair control module 1180 can cause such tilting in a manner synchronized with the video game. Thus, the tilting can occur substantially simultaneously with the tilting in the video game. Furthermore, the degree and / or duration of the tilting can correspond to the degree and / or duration of the tilting in the video game. In some configurations, the actuator 200 can be configured to provide a lifting force of greater than 38 Newtons (N).

[0089] It will be appreciated that the configurations described herein can provide many advantages, including one or more of the advantages mentioned herein. For example, the configurations described herein can provide an enhanced visual content experience. The configurations described herein can provide a haptic "fourth dimensional experience" to the chair occupant. The configurations described herein can provide chair movement timed to movement in visual content presented to the human. The configurations described herein can cause chair movement to be triggered by a video game or movie being watched. The configurations described herein can enable simpler products. The configurations described herein do not require motors or air compressor systems that include gears.

In this regard, each block in the flowcharts or block diagrams may represent a module, segment, or portion of code that includes one or more executable instructions for implementing the specified logical function(s). It should also be noted that in some alternative implementations, the functions noted in the blocks may occur in an order different from the order noted in the figures. For example, two blocks shown in succession may in fact be executed substantially simultaneously, or the blocks may sometimes be executed in the reverse order, depending on the functionality involved.

[0091] The above-mentioned systems, components, and / or processes can be realized in hardware or a combination of hardware and software, and can be realized in a centralized manner in one processing system or in a distributed manner where different elements are distributed across several interconnected processing systems. Any kind of processing system or other device adapted to perform the methods described herein is suitable. A typical combination of hardware and software can be a processing system including a computer usable program code that, when loaded and executed, controls the processing system to perform the methods described herein. The systems, components, and / or processes can also be embedded in a computer readable storage device, such as a machine readable computer program product or other data program storage device, tangibly embodying a program of instructions executable by a machine to perform the methods and processes described herein. Furthermore, these elements can be embedded in an application product that includes all the features enabling the implementation of the methods described herein and that can execute these methods when loaded into a processing system.

[0092] As used herein, the terms "a" and "an" are defined as one or more. As used herein, the term "multiple" is defined as two or more. As used herein, the term "another" is defined as at least a second or more. As used herein, the terms "including" and / or "having" are defined as "comprising" (i.e., open-ended language). The term "or" is intended to mean an inclusive "or" rather than an exclusive "or". As used herein, the phrase "at least one of and" refers to and encompasses any and all possible combinations of one or more of the items listed therein. As an example, the phrase "at least one of A, B, and C" includes only A, only B, only C, or any combination thereof (e.g., AB, AC, BC, or ABC). As used herein, the terms "substantially" or "about" include the term it modifies and slight variations therefrom. Thus, the term "substantially parallel" means exact parallelism and slight variations therefrom. "Slight variations therefrom" can include 15 degrees / percent / unit or less, 14 degrees / percent / unit or less, 13 degrees / percent / unit or less, 12 degrees / percent / unit or less, 11 degrees / percent / unit or less, 10 degrees / percent / unit or less, 9 degrees / percent / unit or less, 8 degrees / percent / unit or less, 7 degrees / percent / unit or less, 6 degrees / percent / unit or less, 5 degrees / percent / unit or less, 4 degrees / percent / unit or less, 3 degrees / percent / unit or less, 2 degrees / percent / unit or less, or 1 degree / percent / unit or less. In some cases, "substantially" can include being within normal manufacturing tolerances.
