Abstract

A chair can be configured for synchronized movement with visual content, such as a video game or movie, presented on a display. The chair can include a seat portion. A plurality of actuators can be operatively positioned to cause a movement of the seat portion. The actuators can include one or more shape memory material members. Each of the actuators being configured such that, when an activation input is provided to the one or more shape memory material members, the one or more shape memory material members change from a first configuration to a second configuration and cause the actuator to morph into an activated configuration. One or more processors operatively connected to selectively activate one or more of the actuators by causing the activation input to be provided to the one or more shape memory material members of at least one of the actuators.

First claim

What is claimed is:

1. A chair, comprising:
a platform;
a seat portion supported on the platform; and
actuators operatively connected to the platform, each actuator including a shape memory material member, each actuator being configured such that, when an activation input is provided to the shape memory material member, the shape memory material member contracts to cause the actuator to morph into an activated configuration in which a height of the actuator increases, the actuators being operatively positioned to cause a movement of the entire seat portion by engaging the platform when selectively activated, each actuator including a rib on an inner side thereof.

2. The chair of claim 1 , wherein the actuators are arranged in a substantially rectangular pattern.

3. The chair of claim 1 , wherein the actuators are arranged in an offsetting substantially parallel pattern.

4. The chair of claim 1 , wherein the actuators are arranged in a substantially radial pattern.

5. The chair of claim 1 , wherein the shape memory material member is a shape memory alloy wire.

6. The chair of claim 1 , wherein each actuator includes:
a first endcap;
a second endcap positioned opposite the first endcap, wherein the shape memory material member is operatively connected to the first endcap and the second endcap;
a first outer member, the first outer member being bowed, the first outer member including a first end and a second end, the first end being operatively connected to the first endcap and the second end being operatively connected to the second endcap; and
a second outer member, the second outer member being bowed, the second outer member including a first end and a second end, the first end being operatively connected to the first endcap and the second end being operatively connected to the second endcap,
wherein the first and second outer members are made of a flexible material and are arranged on opposite sides of the shape memory material member, the first outer member is located above the second outer member.

7. The chair of claim 6 , wherein the platform is supported on the actuators, wherein the platform includes apertures, wherein each of the apertures receives a protrusion of a respective one of the actuators, and wherein the protrusion extends from the first outer member.

8. The chair of claim 6 , wherein the actuator includes a base, and wherein the base is operatively connected to the second outer member.

9. The chair of claim 1 , wherein the chair is a gaming chair.

10. A system, comprising:
a chair including a platform and a seat portion supported on the platform;
actuators operatively connected to the platform, each actuator including a shape memory material member, each actuator being configured such that, when an activation input is provided to the shape memory material member, the shape memory material contracts to cause the actuator to morph into an activated configuration in which a height of the actuator increases, the actuators being selectively actuatable and operatively positioned to cause a movement of the entire seat portion by engaging the platform, each actuator including a rib on an inner side thereof; and
a processor configured to selectively activate one or more of the actuators by causing the activation input to be provided to the shape memory material member of at least one of the actuators.

11. The system of claim 10 , further including:
a display operatively connected to the processor, the display being configured to present visual content thereon.

12. The system of claim 11 , wherein the processor is further configured to:
analyze visual content to determine a corresponding chair movement, the corresponding chair movement being synchronized with at least a portion of the visual content;
select one or more of the actuators to achieve the corresponding chair movement; and
causing an activation input to be provided to the selected one or more of the actuators, whereby the selected one or more of the actuators are activated to cause the seat portion to move according to the corresponding chair movement.

13. The system of claim 10 , further including:
a power source operatively connected to supply electrical energy to the shape memory material member of each actuator, wherein the processor is operatively connected to the power source, wherein the processor is configured to selectively control a supply of electrical energy to the shape memory material member.

14. The system of claim 10 , wherein the actuators are arranged in one of: a substantially rectangular pattern, an offsetting substantially parallel pattern, and a substantially radial pattern.

15. The system of claim 10 , wherein the shape memory material member is a shape memory alloy wire.

16. The system of claim 10 , wherein each actuator includes:
a first endcap;
a second endcap positioned opposite the first endcap, wherein the shape memory material member is operatively connected to the first endcap and the second endcap;
a first outer member, the first outer member being bowed, the first outer member including a first end and a second end, the first end being operatively connected to the first endcap and the second end being operatively connected to the second endcap; and
a second outer member, the second outer member being bowed, the second outer member including a first end and a second end, the first end being operatively connected to the first endcap and the second end being operatively connected to the second endcap,
wherein the first and second outer members are made of a flexible material and are arranged on opposite sides of the shape memory material member, the first outer member is located above the second outer member.

17. The system of claim 10 , wherein the chair is a gaming chair.

18. A method of moving a portion of a chair synchronized with visual content, the chair including a platform, a seat portion supported on the platform, and actuators operatively connected to the platform, the method comprising:
analyzing visual content to determine a corresponding chair movement, the corresponding chair movement being synchronized with at least a portion of the visual content;
selecting one or more of the actuators to achieve the corresponding chair movement; and
causing an activation input to be provided to the selected one or more of the actuators, whereby the selected one or more of the actuators are activated to cause the entire seat portion to move according to the corresponding chair movement,
each actuator including a shape memory material member, each actuator being configured such that, when an activation input is provided to the shape memory material member, the shape memory material member contracts to cause the actuator to morph into an activated configuration in which a height of the actuator increases, the actuators being operatively positioned to cause a movement of the entire seat portion by engaging the platform when selectively activated, each actuator including a rib on an inner side thereof.

19. The method of claim 18 , wherein causing the activation input to be provided to the selected one or more of the actuators includes causing electrical energy from a power source to be supplied to the shape memory material member.

20. The method of claim 18 , further including:
discontinuing the activation input to the selected one or more of the actuators.

21. A system, comprising:
a chair including a platform including apertures and a seat portion supported on the plat
