BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Exoskeletons are structures of rigid links mounted on a body that restore, rehabilitate, or enhance the human motor function. Effective use of exoskeletons for restoration or enhancement of motor function has potentially widespread applications in areas such as rehabilitation robotics, injury prevention, performance enhancement, and in helping humans with disabilities or compromised neuromuscular function. However, conventional exoskeleton systems are at an early stage of development, with some progress having been made in the field of rehabilitation.
[0004] Conventional methods of operating the exoskeletons include brain reading techniques to detect the pulses sent out by the brain for desired movements. But no such sensor or instrument is currently available to perfectly identify the desired movement of a person we can read the type of brain wave (alpha, beta, etc.) but extracting information of the desired task from that data is a very difficult and cumbersome process as a lot of computing is required and after that the results are not very accurate. The prediction of desired action is not very accurate in the process EEG which is the main requirement in an exoskeleton suit designed to support the user. There also exist some other techniques such as the use of electrodes embedded inside the human skin in order to obtain more precise data but this is very harmful as it damages the brain tissues which may cause a temporary or permanent memory loss. Also, the above described methods involve very complex computations and thus increase the cost of exoskeleton.
[0005] There is, therefore, a requirement to have a technique of controlling the movement of different limbs of the exoskeleton at a reduced cost and complexity.

[0042] FIG. 2 illustrates an exemplary module diagram 200 of systemfor controlling the Exoskeleton, in accordance with an embodiment of the present disclosure.
[0043] As illustrated, the module diagram 200of the system may comprise one or more processor(s) 202. The one or more processor(s) 202 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and/or any devices that manipulate data based on operational instructions. Among other capabilities, the one or more processor(s) 202 are configured to fetch and execute computer-readable instructions stored in a memory 206 of the system 102. The memory 204 may store one or more computer-readable instructions or routines, which may be fetched and executed to create or share the data units over a network service. The memory 204 may comprise any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as EPROM, flash memory, and the like.
[0044] The system may also comprise an interface(s) 206. The interface(s) 206 may comprise a variety of interfaces, for example, interfaces for data input and output devices, referred to as I/O devices, storage devices, and the like.

Examples of such components include, but are not limited to, processing engine(s) 208 and data 210. For example,
[0045] The processing engine(s) 208 may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processing engine(s) 208. In examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processing engine(s) 208 may be processor executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processing engine(s) 208 may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the machine-readable storage medium may store instructions that, when executed by the processing resource, implement the processing engine(s) 208. In such examples, the system may comprise the machine-readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium may be separate but accessible to system and the processing resource. In other examples, the processing engine(s) 208 may be implemented by electronic circuitry.
[0046] The data 210 may comprise data that is either stored or generated as a result of functionalities implemented by any of the components of the processing engine(s) 208 or the system. With reference to FIG. 1, the present disclosure relates to a system for controlling a exoskeleton using one or more eye parameters. A pre-defined eye-parameters and the respective limb operation cab be stored in the dataset which can be used by the system to detect the desired operation of the limbs by tracking the eye parameters. For example two consecutive blinks of left eyelid within an interval of two seconds for a pre-defined interval time can be associated with movement of right arm or right leg. Similarly, a number of eye parameters can be associated with movement (also referred as dataset, herein) of one of more limbs 108 of the exoskeleton, and can be stored in the memory. The system can include an eyewear 102 that can be worn by a user. The eyewear can be used to track the eye parameters of the user, and generate a set of first signals representing the eye parameters (also referred as one or more eye parameters, herein). The set of first signals can be send to one or more processing units 104 having one or more processors 202 associated with memory 208. The set of first signals can be received by the one or more processing units 104 using a receiving engine 212. The
[0047] In an embodiment, the processors 202 can extract the eye parameters from the set of first signals using an extraction engine 214, and then the extracted eye parameters can be matched, using the matching engine 216, with the dataset to identify the associated limb movement with the extracted eye parameters. Based on the matching results, a set of control signals are generated representing desired or associated limb movement. The set of controls signals are sent to one or more actuating devices 106 for moving the associated limbs of the exoskeleton.
[0048] FIG. 3 illustrates an exemplary method 300 for controlling the Exoskeleton, in accordance with an embodiment of the present disclosure.
[0049] As illustrated, in step 302one or more eye parameters of a user wearing the eyewear 102 can be detected by an imaging device, and a sensing device present in the eyewear 102. In step 304, a set of signals based on detected the one or more eye parameters can be generated by the imaging device and the sensing device. In step 306, the set of first signals are received by the one or more processing unit operatively coupled with the imaging device and the sensing device. In step 308, the one or more eye parameters from the set of first signals are extracted by the one or more processing unit. In step 310, the extracted one or more parameters are matched by the one or more processing device, with a pre-defined parameters stored in a dataset. In step 312, a set of control signals representing the movement of one or more limbs of the exoskeleton, are generated by the one or more processing device. In step 314, the one or more limbs of the exoskeleton are moved by the one or more actuating device that are operatively coupled with the one or more processing units, based on received the set of control signals.
[0050] In an embodiment, the proposed exoskeleton can help a differently abled person in moving his/her skeleton by using his/her eyes only, unlike the conventional exoskeleton system that used complex brain signals instead. Eye movement (based on user’s ease) and the corresponding required action of a particular limb can be pre-stored in a database. At the time of using his particular limb, the used can perform a specific eye movement such as contraction the pupil etc. The eye movement can be captured by the imaging device mounted on an eyewear worn by the user. The imaging device can send a corresponding signal (also referred as set of first signals, herein) to processing unit. The associated action of a particular limb (such as gripping a glass, sitting, moving an arm etc.) can be detected and the exoskeleton can be signaled for performing the associated action. In this way the proposed system can simply the functioning of the exoskeleton.
