“…wearable devices(exoskeletons) can be used to feel forces of mechanical systems like in the TESLAGLOVE which is used in teaching simulators. Some Haptic devices can even be assembled as a training itself, and used to teach dynamics and controls when used in simulation [28] [29]. video games joystick can be reprogmmed to work with developed simulations to teach engineering students about moment of inertia, internal forces diagrams, and statics reaction problems [30].…”

Teaching STEM subjects requires making concepts as intuitive as possible, a student must relate between mathematical expressions and what he can feel and observe in real life. The golden rule for teaching is to make students participate and use as many sensations as possible (Active learning). Computers and teaching simulations have been the perfect tool for educators, but for so long they have been heavily relying on audition and sight only (passive learning). The integration of Haptic technology (Perception via touch) into these teaching simulations has helped revolutionize the educational system. the advantage of using haptic devices is that it converts passive learning into active learning, which is considered to be the core of teaching STEM subjects, as they rely on lots of practical(hands-on) work.it offers a physical interaction between students and the phenomena required to comprehend. This review introduces haptic technology and how it can be utilized in education, discuss the benefits of active learning and its advantages over passive learning, Covers the latest haptic devices used in the different educational fields, Covers the challenges facing the wide spread usage of this technology, and finally Gives hints on how this technology can be further utilized.

“…The motion of the device and operator are coupled, and the operator dynamics close the force loop, creating additional feedback. A simple one-degree-of-freedom haptic paddle [71,72,73,74,75,76] was produced for the purpose of implementation and testing, shown in Figure 7. This design was chosen for versatility and low cost, and was scaled up for increased force capability.…”

Improved stability of haptic human–robot interfaces using measurement of human arm stiffness

Necessary physical contact between an operator and a force feedback haptic device creates a coupled system consisting of human and machine. This contact, combined with the natural human tendency to increase arm stiffness to attempt to stabilize its motion, can reduce the stability of the system. This paper proposes a method to increase stability on demand while maintaining speed and performance. Operator arm stiffness is not directly measurable, so controllers cannot typically account for this issue. The causes of arm end-point stiffness are examined as related to system stability, and a method for estimating changes in arm stiffness based on arm muscle activity was designed to provide a robotic controller with additional information about the operator. This was accomplished using EMGs to measure muscle activities and estimating the level of arm stiffness, which was used to adjust the dynamic characteristics of an impedance controller. To support this design, the correlation between EMGs and arm stiffness was validated experimentally. Further experiments characterized the effects of the designed system on operator performance. This showed increased stability and faster, more accurate movements using the compensating system. Such a system could be used in many applications, including force assisting devices in industrial facilities.

“…Grounded interfaces are able to display forces that come from grounded sources without ambiguity. As the literature shows, they are able to display an object's geometric characteristics such as size, shape and texture (Minsky et al, 1990), as well as a system's dynamic characteristics such as mass, stiffness and friction (MacLean, 1996;Richard et al, 1997).…”

Two haptic interfaces, each able to provide either grounded or ungrounded haptic feedback, were constructed. Tests were conducted to compare a subject’s ability to perform boundary detection and object size discrimination tasks with grounded or ungrounded haptic feedback, with or without vision. Not surprisingly, grounded feedback is better than ungrounded feedback in displaying forces that stem from grounded sources. However, ungrounded haptic feedback can give comparable results in boundary detection tests. Subjects also reported that the application of forces to the fingertips by a moving paddle, as employed in the ungrounded tests and in some of the grounded tests, enhanced the realism of the virtual boundary contacts. Additional results concerning the synchronization of different feedback mechanisms and the use of a brake for grounded feedback are discussed in terms of their implications for the design of haptic interfaces.
