Design and Development of Assistive Device for Person with Disabilities

Assistive technology advances more prominent autonomy by empowering individuals to perform tasks that they were once in the past not able to fulfill, or had extraordinary trouble finishing it, by giving upgrades to, or changing methods for interacting with the technology expected to finish such tasks. Our aim of this project is to design an assistive device for physically disabled persons. People with disabilities may utilize assistive device all alone or with the backing of other individuals. To design and develop a new assistive device, we need to know the sorts of disabilities and the current existing assistive devices. There are numerous sorts of assistive devices, all of which have a real part in enhancing individuals' lives, for example, wheelchairs, scooters, walkers, canes, crutches, prosthetic devices to upgrade their mobility. Our primary aim is to design assistive device with considerably more enhanced base. We have chosen to design and develop a motorized, voice-operated wheelchair. A standard wheelchair will be altered to meet our project's objectives. Finally, a working model will be submitte

Comics, robots, fashion and programming: outlining the concept of actDresses

This paper concerns the design of physical languages for controlling and programming robotic consumer products. For this purpose we explore basic theories of semiotics represented in the two separate fields of comics and fashion, and how these could be used as resources in the development of new physical languages. Based on these theories, the design concept of actDresses is defined, and supplemented by three example scenarios of how the concept can be used for controlling, programming, and predicting the behaviour of robotic systems

The digital architecture of time management

This article explores how the shift from print to electronic calendars materializes and exacerbates a distinctively quantitative, “spreadsheet” orientation to time. Drawing on interviews with engineers, I argue that calendaring systems are emblematic of a larger design rationale in Silicon Valley to mechanize human thought and action in order to make them more efficient and reliable. The belief that technology can be profitably employed to control and manage time has a long history and continues to animate contemporary sociotechnical imaginaries of what automation will deliver. In the current moment we live in the age of the algorithm and machine learning, so it is no wonder, then, that the contemporary design of digital calendars is driven by a vision of intelligent time management. As I go on to show in the second part of the article, this vision is increasingly realized in the form of intelligent digital assistants whose tracking capacities and behavioral algorithms aim to solve life’s existential problem—how best to organize the time of our lives. This article contributes to STS scholarship on the role of technological artifacts in generating new temporalities that shape people’s perception of time, how they act in the world, and how they understand themselves

A novel collaboratively designed robot to assist carers

© Springer International Publishing Switzerland 2014. This paper presents a co-design process and an assisted navigation strategy that enables a novel assistive robot, Smart Hoist, to aid carers transferring non-ambulatory residents. Smart Hoist was codesigned with residents and carers at IRT Woonona residential care facility to ensure that the device can coexist in the facility, while providing assistance to carers with the primary aim of reducing lower back injuries, and improving the safety of carers and patients during transfers.The Smart Hoist is equipped with simple interfaces to capture user intention in order to provide assisted manoeuvring. Using the RGB-D sensor attached to the device, we propose a method of generating a repulsive force that can be combined with the motion controller’s output to allow for intuitive manoeuvring of the Smart Hoist, while negotiating with the environment.Extensive user trials were conducted on the premises of IRTWoonona residential care facility and feedback from end users confirm its intended purpose of intuitive behaviour, improved performance and ease of use

Learning shared control by demonstration for personalized wheelchair assistance

An emerging research problem in assistive robotics is the design of methodologies that allow robots to provide personalized assistance to users. For this purpose, we present a method to learn shared control policies from demonstrations offered by a human assistant. We train a Gaussian process (GP) regression model to continuously regulate the level of assistance between the user and the robot, given the user's previous and current actions and the state of the environment. The assistance policy is learned after only a single human demonstration, i.e. in one-shot. Our technique is evaluated in a one-of-a-kind experimental study, where the machine-learned shared control policy is compared to human assistance. Our analyses show that our technique is successful in emulating human shared control, by matching the location and amount of offered assistance on different trajectories. We observed that the effort requirement of the users were comparable between human-robot and human-human settings. Under the learned policy, the jerkiness of the user's joystick movements dropped significantly, despite a significant increase in the jerkiness of the robot assistant's commands. In terms of performance, even though the robotic assistance increased task completion time, the average distance to obstacles stayed in similar ranges to human assistance

Human-Robot Interaction for Children with Cerebral Palsy: Reflection and Suggestion for Interactive Scenario Design

AbstractThis paper explains how a humanoid robot NAO can be used as an assistive technology in specific therapy for children with cerebral palsy (CP). The role of the robot is to motivate the children as to keep them engaged in therapy. To achieve this, the robot must have appropriate appearance to be able to establish affective engagement between child and robot. In addition, the robot should exhibit the right therapeutic approach of managing children with CP. How the humanoid robot NAO acts as a tool to assist in improving the outcome of conventional therapy especially by imitation learning will also be explained. Four interactive scenarios in human-robot interaction (HRI) were designed based on the measurement items in Gross Motor Functional Measure (GMFM). The scenarios will then be constructed based on suitability that will be executed by the robot. As a result from the discussions between clinicians, therapists and engineers, four interactive scenarios consists of introductory rapport, sit to stand, body balancing and ball kicking activity have been formulated. The study has been performed in collaboration between the Faculty of Medicine and the Faculty of Mechanical Engineering at the Medical Specialist Centre, Discipline of Rehabilitation Medicine, Faculty of Medicine, UiTM Sungai Buloh, Selangor, Malaysia

Exploring Assistive Technology for Assistance Dog Owners in Emergency Situations

Many vulnerable individuals own an assistance dog. Previous work has shown that a domestic alarm, Ringsel, allows assistance dogs to "call for help" via a canine interface that they interact with by pulling a detachment off with their mouths. Here we discuss the potential for systems like the Ringsel to leverage distinct behavioral patterns exhibited by the canine users to aid the automatic detection of emergencies by being used in coordination with existing assistive technologies for emergency detection and response
