In some embodiments, the reference gestures may be customized for a particular user or group of users. cause at least one door of an elevator car to be controlled based on the second gesture.

The external image capture device 132 may communicate captured image information to the media device 102 using any suitable communication medium, including physical wires, light, or radio frequency . In practice, the output of the classification process will be a continuous real value, where high values indicate high confidence that the gesture was made. For example, when detecting a sub-action that is a combination of six sub-vectors from each frame, it is possible that only 4 are detected meaning a weaker detection was made.

The technical effects and benefits of the detection system 200 include gesture based door operations that improves a passenger experience, along with implementing gesture based hall call capabilities. The technical effects and benefits of the detection system 200 include eliminating door stuck problems, which are responsible for major service turn-backs, based on improper passenger use of the tactile sensors. Although shown and described with a roping system including tension member 107, elevator systems that employ other methods and mechanisms of moving an elevator car within an elevator shaft may employ embodiments of the present disclosure. For example, embodiments may be employed in ropeless elevator systems using a linear motor to impart motion to an elevator car. Embodiments may also be employed in ropeless elevator systems using a hydraulic lift to impart motion to an elevator car. 1 is merely a non-limiting example presented for illustrative and explanatory purposes. The controller 115 is located, as shown, in a controller room 121 of the elevator shaft 117 and is configured to control the operation of the elevator system 101, and particularly the elevator car 103.

When activated, it follows hand movements by using three sensors to do depth analysis, and by doing so, can understand a human’s position in a room and a particular body part’s movement. However, if interaction technologies are overly obtrusive or constraining, then the user’s experience with this synthetic automation world will be severely degraded. If the interaction draws attention to the technology, rather than the task, or imposes a high cognitive load on the user, it becomes a burden and obstacle to the process. Sometimes traditional mouse/keyboard-oriented graphical interfaces are not well suited to large, complex tasks. As a result, speech and gesture-based inputs are making industrial plant and process automation faster and more efficient by providing natural, efficient, powerful, and flexible interactions. Human gestures and languages are natural and flexible and may often be efficient and powerful, especially as compared with alternative interaction modes.

It consists of building a spatial-temporal descriptor of a high order function , obtained by concatenating the feature vectors at consecutive frames of the sequence. The concatenated feature vector is then passed to a classifier which determines if it corresponds to the target gesture. 8 illustrates the second type of approach, where one makes use of a state machine that allows one to account for the recognition of the different sub-actions in the sequence. Each state applies a classifier that is specifically trained to recognize one of the sub-actions. 7 depicts a two-part user gesture (sub-action 1 and sub-action 2) that is made up of two sub-actions in accordance with one or more embodiments.
One or more program content streams 136 are received by the program content stream interface 104. One or more tuners 104 a in the program content stream interface 104 selectively tune to one of the program content streams 136 in accordance with instructions received from the processor system 106. The program content stream 136 typically comprises a plurality of programs multiplexed together. The processor system 106, Gesture Control for elevator based upon a request for a program of interest specified by the user 128, parses out program content associated with the program of interest. The program content is then assembled into a stream of video and/or audio information which may be saved into the program buffer 110 such that the program content can be streamed out to the media presentation device, such as the television 134, via the device interface 114.

In some embodiments, the gesture interface 206 may include one or more feedback devices 224 to provide an affirmative indication to the user that the gesture has been recognized. In some embodiments, the feedback may simply indicate that a gesture has been recognized. In some embodiments, the feedback may indicate the type of action that the gesture interface 206 recognized. A user may be able, or may be required, to confirm the feedback before elevator resources are provisioned for the requested service/functionality.
The hospital is also implementing a robotic porter system where fleets of robot workers carry clinical waste, deliver food, clean the operation theatres, and dispense drugs by recognizing speech commands. Staff use handheld PDAs to call robots—which also respond to voice commands—to move meal trays, linen, or other supplies. The robot comes up in a service lift by itself, picks up the item, and returns to the lift by following a system of pre-programmed routes that use laser beams to tell the robot where it is and where it needs to go. Computers onboard the robots tell doors to open and sensors instruct the robots to stop if anything, or anyone, is in the way.
Alternatively, or additionally, the parsed out program content may be saved into the DVR 112 for later presentation. Further, it is appreciated that the other hand 130 b of the user 128 may, or may not be, moved with the intention of generating a command.

If the elevator door status is closed, the process flow 400 returns to block 410 where the elevator door status is read again. If the elevator door status is open, the process flow 400 proceeds to decision block 430 where the gesture detection unit determines if a door closed command has been generated by the door control subsystem. If the door closed command has not been generated, the process flow 400 returns to decision block 430 . If the door closed command has been generated, the process flow 400 proceeds to block 440 . 3, the one or more gesture sensors 305 generate a detection zone 350 in front of the set of hall doors 307. For instance, the user A is detected by the gesture sensors 305.1, 305.2, and 305.3, and thus is determined to be within the detection zone 350.
Because the mechanic frequently encountered the same types of problems, he had developed a set of ‘habitualized’ gestures he used when faced with familiar problems. These gestures had similar forms every time he used them and were closely based on the motor patterns he used when solving the problems in the real world. These types of routinized gestures lie somewhere between iconic representational gestures and conventional gestures because they use the same movement pattern every time. Excella Electronics specialises in manufacturing and supplying motion control devices, industrial electronic instruments, elevator control and safety systems and automation products. Through a strategy of continuous improvement and teamwork, we are dedicated to establishing the highest industry standards for quality, value, service and technology. While limiting gestures on a system that requires quick adoption is incredibly important, it is worth also considering use cases where users can be trained over time.
The cameras 210.1-210.3 can provide the location of the user 260 and the gesture from user 260 that can be processed to determine a call to an elevator 250. Processing the location and gesture can be used to generate a user path 270 through the building floor to the elevator. This generated path 270 estimate can be used to provide an estimate time of arrival at the elevators.

Further, the position of the user's hand at the initial location 302 during the first, channel up hand gesture has the user's index finger extending in an upwards direction (similar to the position of the user's hand at the ending location 306). During the second hand gesture, the closed hand or first position of the user's hand is used . Thus, in this example, the position of the user's hand while at the initial location 302 is relevant to determination of the intended command of the user 128. A plurality of exemplary control buttons and their associated functionality are described in Table 1 below.
If a future standard could specify additional measurement data, sensing accuracy would improve. Meanwhile, the technology’s efficiency stands to benefit by exposing each device’s sensing capabilities at the medium access control layer. Connected light fixtures, multi-room audio, and climate control systems could come alive and then fade to black as family members enter and leave rooms—all without the cost or complexity of passive infrared sensors for motion detection.
Although shown in a controller room 121, those of skill in the art will appreciate that the controller 115 can be located and/or configured in other locations or positions within the elevator system 101. In one embodiment, the controller may be located remotely or in the cloud. According to one or more embodiments or any of the above elevator system embodiments, the one or more gesture sensors can generate a detection zone for detecting at least one user. According to one or more embodiments or any of the above detection system embodiments, at least two of the one or more gesture sensors can detect the at least one user before motion detection is enabled. The elevator system of claim 8, wherein the gesture detection unit applies digital filters to the motion to output a pattern that is compared to a list of motions formats to determine whether the pre-determined hand gesture format is found within the motion. The elevator system of claim 11, wherein at least two of the one or more gesture sensors detect the at least one user before motion detection is enabled.
