Abstract: This study is based on the human-machine interaction that is the way of communication between automatic systems and people. The HMI process allows humans to control the machine through initiatives behaviours and natural. Those factors also lead to building the established communication process with the technology and digital system as well. From this study, it has been seen that H2M devices include a sensor for measuring the comments signal such as voice, touch, and gestures for constructing an updated system to control and a measurement system to measure the electrophysiological signals. This study has also focused on the Sensor HMI that can help to detect the temperature and strain pressure. It can provide the opportunity to monitor and mimic human senses and it also can improve machine control by graphene, carbon nanotubes, hydrogel composites, and Ag nanowires. These kinds of elements give the provision to build a stretchable sensor for developing the structure's stretchability. Accordingly, it can be said that the mechanical sensor process assists to apply the attachment of the enabling strain sensors in the finger joints for measuring the movements of the figure and using the pressure sensor for improving the analysis of grasping activities. This study has also shed light on the Actuators of HMI that helps to deliver all kinds of human output and also have the ability to mimic the sense of people or individual for the desired outcome of human and machine interaction. It can help to stimulate the senses of humans mechanically. In this context, it can be said that wearable gloves use the benefits of soft actuators for rehabilitation. It helps to support the force of grasping. On the other hand, the mechanical vibration process helps to stimulate the human sense that helps to provide certain information as well. Intelligence-aided devices usage is one of the other critical parts of this study and from this portion, it has been seen that the advancement of actuators and sensors in machine intelligence help to get higher detectability in soft sensors, coping with chronic problems, and decoupling unwanted stimuli in sensor process. This factor helps human hands to provide the highest degree of freedom in the body for performing a range of tasks with the development of detecting hand motions. This study has chosen a secondary process to get the data for the study and it also helps to make a proper conclusion for the study. At last, it can be said that HMI is a blessing for the world population and future generations.
