Description
BACKGROUND AND SUMMARY OF THE INVENTION

The present invention relates to a self-adjusting chair that uses measurements of an occupant to automatically adjust at least one property of the chair. Professional and amateur gamers often sit in a gaming chair for long hours while playing video games. This extended duration of sitting may cause short-term fatigue and lead to long-term problems such as diabetes. However, the only current solution is to pause the game and take a break, which may cause the player to lose momentum or give up time-critical opportunities within the game.


Exemplary embodiments of the invention provide systems and methods for automatically adjusting a chair in response to measurements of the occupant. The measurements may include biometric measurements. Various sensors may be used to obtain the measurements. Some non-limiting examples of the sensors may include visible cameras, infrared cameras, skin conductance sensors, pressure sensors, temperature sensors, humidity sensors, lidar systems, accelerometers, and magnetometers. Some non-limiting examples of the biometric measurements may include the pressure of the occupant on different sections of the chair, the temperature of the occupant, the humidity of the occupant, the heart rate of the occupant, the skin conductance of the occupant, the posture of the occupant, and the facial expression of the occupant. Some non-limiting examples of other measurements may include the distance from the occupant to a component outside of the chair, such as a table or a monitor.


The measurements may be provided to a processor that uses the measurements to assess the condition of the occupant and provide instructions to actuators to adjust the chair. In some examples the processor may provide the data to a trained artificial intelligence model. The instructions may cause the actuators to adjust various properties of the chair, such as the position, orientation, height, hardness, motion, and/or climate of different sections of the chair. These adjustments may be selected to stimulate the blood circulation of the occupant, provide physical support to the occupant, and/or correct the posture of the occupant. These adjustments may be small and unnoticeable by the occupant; however, they may keep the occupant alert and reduce detrimental health effects due to poor posture and extended periods of sitting in the chair.

The master control server 715 may include various components such as a Modbus Transmission Control Protocol (TCP), a MySQL database, a media player, a Message Queuing Telemetry Transport (MQTT) broker, a virtual network computing (VNC) system, and an application programming interface (API). Third parties may access the master control server 715 via the API, which may be shielded by a firewall 730. The cloud services 725 may include a spectator cloud API and a service API. The application 720 may be hosted on a device such as a smartphone or a tablet, and may provide an interface to the master control server 715 for the occupant or a presenter.


The controller 710 may be a programmable logic controller (PLC), and may include a processor that receives signals from the sensors that indicate the various characteristics of the occupant discussed above. The processor may analyze the data within the signals to determine the condition of the occupant and/or to determine instructions to send to the actuators to adjust at least one property of the self-adjusting chair 100. The condition of the occupant may include the occupant's blood circulation, body temperature, posture, muscle strain, electrical conductivity, and/or sweating. In some examples, the processor may input the data into a trained artificial intelligence model. Various training methods may be used, such as supervised learning, unsupervised learning, and reinforcement learning. Further, various models may be trained, such as artificial neural networks, decision trees, support-vector machines, Bayesian networks, and genetic algorithms. In other examples, the processor may refer to pre-programmed modes for the occupant that indicate how to adjust the self-adjusting chair 100 based on at least one characteristic of the occupant. The processor may then send the instructions to at least one of the actuators to implement the adjustment or adjustments. In one example, if the temperature, humidity, and/or skin conductance of the occupant exceeds a threshold, the processor may instruct a valve that is assigned to at least one of the air nozzles HN, BN, or SN to provide cooled air to the occupant. In another example, if the distance of the occupant from the edge of the table 215 exceeds a threshold, the processor may instruct a motor that is assigned to the self-adjusting chair 100 to move the self-adjusting chair 100 closer to the table 215 along the longitudinal direction 1. Alternatively, the processor may instruct a motor that is assigned to the table 215 to move the table 215 closer to the self-adjusting chair 100 along the longitudinal direction 12.

FIGS. 8A and 8B show a schematic diagram of a method for adjusting a property of the self-adjusting chair 100 based on a measured characteristic of the occupant. As shown in FIG. 8A, the occupant 810 is bending over and has poor posture for playing a video game. For example, the posture of the occupant 810 may be detected by a camera or the lidar system L. The controller 710 may receive a signal from the camera and/or the lidar system L that indicates the posture of the occupant 810. The controller 710 may then analyze the data within the signal to determine at least one adjustment to be made to the self-adjusting chair 100 to correct the posture of the occupant 810. As shown in FIG. 8B, the heights of pneumatic pads 815 in the backrest and seat of the self-adjusting chair may be reduced. In addition, the positions and/or the elasticity profiles of the pneumatic pads 815 may be changed in order to realign the back and/or legs of the occupant 810 to a more upright orientation.



FIGS. 9A and 9B show a schematic diagram of a method for adjusting another property of the self-adjusting chair 100 based on a measured characteristic of the occupant. As shown in FIG. 9A, the occupant 810 is in a relaxed mode while taking a short break from playing a video game. The controller 710 may identify the relaxed mode based on information provided by the pressure sensors P, the camera, and/or the lidar system L. Accordingly, the controller 710 may send a signal to a motor instructing the motor to partially recline the backrest of the self-adjusting chair 100. As shown in FIG. 9B, the occupant 810 has moved to a sleep mode. Again, the controller 710 may identify the sleep mode based on information provided by the pressure sensors P, the camera, and/or the lidar system L. Accordingly, the controller 710 may send a signal to a motor instructing the motor to fully recline the backrest of the self-adjusting chair 100, and the controller may send a signal to the valves 120a-120e to soften the pneumatic pads 815 in order to provide for a more comfortable sleeping position. Here the pneumatic pads 815 may correspond to some or all of the pneumatic pads SE, SI, and LU shown in FIG. 4.



FIG. 10 shows an example of a method 1000 for automatically adjusting at least one property of the self-adjusting chair 100. As shown in FIG. 10, the method begins at block 1010, where a characteristic of an occupant of a chair is measured. A single characteristic or a plurality of characteristics may be measured by a single sensor or a plurality of sensors. For example, a pressure sensor may measure a pressure applied by the occupant to a region of the chair, a temperature sensor may measure a temperature of the occupant, a humidity sensor may measure a humidity of the occupant, a skin conductance sensor may measure a skin conductance of the occupant, an accelerometer may measure a motion of the occupant, a magnetometer may measure an orientation of the occupant, a lidar system may measure a posture of the occupant and/or a distance of the occupant from an object outside of the chair, and/or a camera may measure a posture and/or a facial expression of the occupant.


The sensor then transmits a signal that indicates the characteristic of the occupant at block 1015. The signal may indicate the characteristic of the occupant at a single point in time or over a period of time. Alternatively, the sensor may transmit a plurality of signals over time that indicate the characteristic of the occupant over time. If the sensor measures more than one characteristic of the occupant, the signal may indicate some or all of the characteristics that were measured by the sensor.


The controller then receives the signal from the sensor at block 1020. The controller may receive a plurality of signals from one sensor. Alternatively or in addition, the controller may receive one signal or a plurality of signals from a plurality of sensors. Each signal may indicate one characteristic of the occupant or a plurality of characteristics of the occupant that were measured by the sensor.


The controller then instructs at least one actuator to adjust at least one property of the chair based on the characteristic of the occupant at block 1025. The controller may analyze the measured characteristic or characteristics of the occupant to assess the condition of the occupant and determine instructions to send to at least one actuator based on the condition of the occupant. Alternatively or in addition, the controller may refer to the measured characteristic or characteristics of the occupant and determine instructions to send to at least one actuator by using a look-up table or another reference method. Further, the controller may determine the instructions by providing the measured characteristic or characteristics of the occupant to a trained artificial intelligence model and receiving the instructions from the trained artificial intelligence model. The controller may then send the instructions to at least one of the actuators to implement the adjustment or adjustments to the chair. The controller may also send instructions to other components, such as a table or monitor within the system, to adjust a property or properties of the other components based on the measured characteristic or characteristics of the occupant.
