Mouse for Computer Control from the Joystick of the Wheelchair

DOAJ (DOAJ: Directory of Open Access Journals), 2012

Becoming autonomous is one of the biggest challenges for many people with disabilities. Increasing their autonomy usually involves the use of both a wheelchair and any kind of digital assistant such as a computer or a tablet to communicate, to work or even only for leisure. In such situations, those people are forced to use two different human interfaces, one to move a pointer and the other to drive the wheelchair. A joystick is the most common commercial solution to control a wheelchair whereas there are many different adapted interfaces to emulate the use of a mouse. In this paper we propose the use of a wheelchair joystick as a human interface for electronic devices such as computers, tablets or smartphones. This designed system captures the motion of the joystick on a wheelchair to move the cursor or the pointer of any digital device including an USB port. It avoids any mechanical or electronic change in the joystick to keep its original safety and warranty. This non-invasive mouse is fast and simple to install. In addition, it is fully configurable to meet any potential user needs. Communication between the device and the computer (or any other digital assistant) uses the USB protocol, although it could be easily upgraded to a Bluetooth wireless connection. To verify the designed system it has been tested by different people: users with disabilities, and physiotherapists and other professionals in disabled people with positive results.

Development of a New Intelligent Joystick for People with Reduced Mobility

Applied bionics and biomechanics, 2018

Despite the diversity of electric wheelchairs, many people with physical limitations and seniors have difficulty using their standard joystick. As a result, they cannot meet their needs or ensure safe travel. Recent assistive technologies can help to give them autonomy and independence. This work deals with the real-time implementation of an artificial intelligence device to overcome these problems. Following a review of the literature from previous work, we present the methodology and process for implementing our intelligent control system on an electric wheelchair. The system is based on a neural algorithm that overcomes problems with standard joystick maneuvers such as the inability to move correctly in one direction. However, this implies the need for an appropriate methodology to map the position of the joystick handle. Experiments on a real wheelchair are carried out with real patients of the Mohamed Kassab National Institute Orthopedic, Physical and Functional Rehabilitation ...

Shared control for wheelchair interfaces

2018

Independent mobility is fundamental to the quality of life of people with impairment. Most people with severe mobility impairments, whether congenital, e.g., from cerebral palsy, or acquired, e.g., from spinal cord injury, are prescribed a wheelchair. A small yet significant number of people are unable to use a typical powered wheelchair controlled with a joystick. Instead, some of these people require alternative interfaces such as a head- array or Sip/Puff switch to drive their powered wheelchairs. However, these alternative interfaces do not work for everyone and often cause frustration, fatigue and collisions. This thesis develops a novel technique to help improve the usability of some of these alternative interfaces, in particular, the head-array and Sip/Puff switch. Control is shared between a powered wheelchair user, using an alternative interface and a pow- ered wheelchair fitted with sensors. This shared control then produces a resulting motion that is close to what the use...

Joystick Controlled Wheelchair

2017

A joystick control wheelchair is very important for the physically challenged people. They cannot move anywhere like a normal person. For this reason they always depend on the other people. But the joystick control wheelchair can removed this problem and help them to move anywhere. The movement of wheelchair can be control manually by the joystick. The command is implemented by using joystick and then the command is sent to the Arduino board where the controller ATMega328p will process the command. After processing the controller send the command in the form of digital signal to the motor driving IC and the motor driving IC control the movement of wheelchair.

Intelligent Control Wheelchair Using a New Visual Joystick

Journal of healthcare engineering, 2018

A new control system of a hand gesture-controlled wheelchair (EWC) is proposed. This smart control device is suitable for a large number of patients who cannot manipulate a standard joystick wheelchair. The movement control system uses a camera fixed on the wheelchair. The patient's hand movements are recognized using a visual recognition algorithm and artificial intelligence software; the derived corresponding signals are thus used to control the EWC in real time. One of the main features of this control technique is that it allows the patient to drive the wheelchair with a variable speed similar to that of a standard joystick. The designed device "hand gesture-controlled wheelchair" is performed at low cost and has been tested on real patients and exhibits good results. Before testing the proposed control device, we have created a three-dimensional environment simulator to test its performances with extreme security. These tests were performed on real patients with d...

Interaction design for wheelchair using Nintendo Wiimote controller

2011

Impaired people require additional attention by the people around them and also by the people who design artifacts and tools for them. We investigate the interaction design aspects of a wheelchair controller, developed by embedded software engineers in the laboratory, according to the rules of physicality. The purpose of the study is to facilitate impaired people with ease of use while bridging the gap between human-computer interaction and embedded software engineering. By proposing Nintendo's Wiimote as wheelchair controller, we intend to produce intuitive, simple and natural interaction with the wheelchair.

The project implements wheelchair navigation system which implements a wheelchair which can be navigated via speech and gesture. Along with mundane navigation system such as joystick, wheelchair can be operated by speech, touch-screen as well as gesture. Different modules of voice, gesture and touch screen are connected to centre platform and motors which will navigate the wheelchair. In earlier inventions, joystick and voice module has been implemented, but gesture control acts as innovative approach for wheelchair navigation and helps handicapped people. Apart from navigation, wheelchair also has apt acknowledgment of obstacles and it will avoid collision providing more safety to user.
