comparing, via the processor, the gesture data to a predetermined gesture, the predetermined gesture being created by transitioning a hand from a first position to a second position, one of the first position and the second position being a closed fist, a remainder of the first position and the second position being an open palm; determining, via the processor, whether the gesture data matches the predetermined gesture; and commanding, via the processor, the electrically activated device to change from a first state to a second state. ## Claims ### Claim 1 A method of touchless activation of an electrically activated device, comprising: receiving, via a processor and through a sensor in an armrest of a seat in an aircraft cabin of an aircraft, exclusively touchless gesture data from a user, wherein the touchless gesture data is a first and only data received from the user; comparing, via the processor, the touchless gesture data to a predetermined gesture, the predetermined gesture being created by transitioning a hand from a first position to a second position, wherein if the first position is a closed fist, the second position is an open palm, and wherein if the first position is the open palm, the second position is the closed fist; determining, via the processor, whether the touchless gesture data matches the predetermined gesture; and commanding, via the processor, the electrically activated device to change from a first state to a second state. ### Claim 2 (depends on 1) The method of claim 1, further comprising polling, via the processor, the touchless gesture data. ### Claim 3 (depends on 1) The method of claim 1, further comprising testing a confidence level of the touchless gesture data matching the predetermined gesture. ### Claim 4 (depends on 3) The method of claim 3, wherein testing the confidence level of the touchless gesture data matching the predetermined gesture includes determining a probability the touchless gesture data matches the predetermined gesture. ### Claim 5 (depends on 4) The method of claim 4, wherein the confidence level is greater than 80%. ### Claim 6 (depends on 1) The method of claim 1, wherein the predetermined gesture further comprises fingers of the user being spread apart and extended distally from the open palm. ### Claim 7 (depends on 1) The method of claim 1, wherein the sensor is a motion sensor. ### Claim 8 A gesture-based system, comprising: an armrest in an aircraft cabin of an aircraft; a sensor coupled to the armrest and oriented orthogonal to a ground surface in the aircraft cabin; a controller in operable communication with the sensor, the controller configured to: receive, via a processor and through the sensor, exclusively touchless gesture data from a user, wherein the touchless gesture data is a first and only data received from the user; compare, via the processor, the touchless gesture data to a predetermined gesture, the predetermined gesture being created by transitioning a hand from a first position to a second position, wherein if the first position is a closed fist, the second position is an open palm, and wherein if the first position is the open palm, the second position is the closed fist; determine, via the processor, whether the touchless gesture data matches the predetermined gesture; and command, via the processor, an electrically activated device to change from a first state to a second state, wherein the gesture-based system is configured to allow a passenger to activate the electrically activated device in an entirely touchless fashion. ### Claim 9 (depends on 8) The gesture-based system of claim 8, wherein the predetermined gesture further comprises fingers of the user being spread apart. ### Claim 10 (depends on 8) The gesture-based system of claim 8, further comprising the electrically activated device in operable communication with the controller, the electrically activated device configured to transition from the first state to the second state in response to the command. ### Claim 11 (depends on 8) The gesture-based system of claim 8, further comprising a passenger service unit (PSU), the controller in operable communication with the PSU. ### Claim 12 (depends on 8) The gesture-based system of claim 8, wherein the controller is further configured to test a confidence level of the touchless gesture data matching the predetermined gesture. ### Claim 13 (depends on 12) The gesture-based system of claim 12, wherein testing the confidence level of the touchless gesture data matching the predetermined gesture includes determining a probability the touchless gesture data matches the predetermined gesture, wherein the touchless gesture data matches the predetermined gesture in response to the probability being greater than 80%. ### Claim 14 An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by a processor, cause the processor to perform operations comprising: receiving, via the processor and through a sensor in an armrest of a seat in an aircraft cabin, exclusively touchless gesture data from a user, wherein the touchless gesture data is a first and only data received from the user; comparing, via the processor, the touchless gesture data to a predetermined gesture, the predetermined gesture being created by transitioning a hand from a first position to a second position, wherein if the first position is a closed fist, the second position is an open palm, and wherein if the first position is the open palm, the second position is the closed fist; determining, via the processor, whether the touchless gesture data matches the predetermined gesture; and commanding, via the processor, an electrically activated device to change from a first state to a second state. ### Claim 15 (depends on 14) The article of manufacture of claim 14, wherein the operations further comprise testing a confidence level of the touchless gesture data matching the predetermined gesture. ### Claim 16 (depends on 15) The article of manufacture of claim 15, wherein testing the confidence level of the touchless gesture data matching the predetermined gesture includes determining a probability the touchless gesture data matches the predetermined gesture. ### Claim 17 (depends on 14) The article of manufacture of claim 14, wherein the predetermined gesture further comprises fingers of the user being spread apart. ### Claim 18 (depends on 14) The article of manufacture of claim 14, wherein the operations further comprise polling, via the processor, the touchless gesture data. ### Claim 19 (depends on 14) The article of manufacture of claim 14, wherein the sensor comprises a motion sensor.
