Omnidirectional Assistive Wheelchair: Design and Control with Isometric Myoelectric Based Intention Classification

Myoelectric Interfaces and Related Applications: Current State of EMG Signal Processing–A Systematic Review

“…The number of channels used in an EMG signal acquisition system is related to the muscles intended to be analyzed. [39], [40] and [45], Prosthetics control [29], [33] and [34] and 10, 12, 16 y 24 channels [27], [28] and [30]- [32].…”

“…The number of channels documented in applications for the interpretation of command gestures is four [27], [28]. These applications are typically used in electrical powered wheelchairs to control functionalities as: moving, stopping, moving forward and reversing.…”

“…• Electric powered wheelchair control: Gain of 455 [28]. From the works that do not specify the amplifier gain, 5 of them are related to prosthetic control applications, 1 to muscular activation monitoring, 2 to exoskeleton activation, 3 to writing recognition, 1 to myoelectric bracelet, 1 to electric powered wheelchair control, and 1 to silent speech recognition.…”

Development of Universal Wheelchair Transporter

“…The improvement started with the transformation of the conventional wheelchair to electrical wheelchair that used the joystick as the movement controller, but this will only compatible for the patient with lower extremity motor impairments [2]. To overcome this issue many inventions of a powered wheelchair with intelligent control system are created to improve the mobility of patient with severe disability [3]. Therefore, the patient with both upper and lower extremity motor impairment can benefit from the improvement of technology used on the wheelchair.…”

“…For example, wheelchair is controlled using vision based controlled [4], speech controlled [2], brain-controlled interfaces [5], and hybrid (gesture and speech) controlled system [1] to run the wheelchair. Most of the researcher are focusing on the control system of the wheelchair including the maneuverability, navigational intelligence, and multi-modal control interfaces [3]. The enhancement of technology has resulted in many developed smart wheelchair and some of the wheelchairs are being commercialized for instance NavChair [6], Smart Power Assistance Module (SPAM) [7] and Mobility Aid for and disabled people (MAid) [8].…”
