Development of a Dual Control System Applied to a Smart Wheelchair, using Magnetic and Speech Control

Using Self-Reliance Factors to Decide How to Share Control Between Human Powered Wheelchair Drivers and Ultrasonic Sensors

“…Robots can perform some tasks without any human involvement [5] but in many situations, a wheelchair driver can benefit from intervention by the sorts of sensor system used by mobile robots [6]. Wheelchair control has been extensively studied [7][8][9][10][11]. Despite that, powered wheelchair control is still challenging because the driver is disabled [12], the environment is largely unknown and complicated, and it is often difficult to understand what (and how much) assistance is really needed [13].…”

Smart Wheelchair with Dual Control using Touchpad and Android Mobile Device

“…The proponents prepared a survey questionnaire to examine the user's perception about the specific functions of the Androidbased touchpad controlled electronic wheelchair. Five questions were prepared to eva luate the touchpad controlled android based electronic wheelchair, namely: (1) the touchpad controller is easy to use; (2) the Android software is easy to use; (3) the sensors work properly; (4) the path finding system works properly; (5) and the electronic wheelchair is easy to use. Each question was rated on how the respondents find the electronic wheelchair efficient and user-friendly using Table 1 as reference.…”

“…This wheelchair project offers people with disabilities [2][3], people who with various degrees of paralysis [4] a chance to navigate. The degree of the paralysis must only be limited either from the lower body, the upper body, except from the fingers, the wrist and the hand [5][6]. Otherwise, the person cannot control it.…”

Development of Universal Wheelchair Transporter

“…Utilization of wheelchair is common in the hospital to ease the movement of the patient from one point to another point. Most hospitals used the conventional wheelchair that needs full assistance from the caretaker to transport the patient even for a simple short straight movement to reach the desired destination [1]. 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].…”

“…Improvements had been done on the controlled system by upgraded from manually to semi auto and fully autonomous controlled system. 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].…”
