The ability to identify the location of human pupil offers us the possibility to know the eye gaze target of a person. This infers the possibility to create new methods of human-machine interaction. Nevertheless there are some barriers and restrictions that are shown in the integrations, as intrusion, robustness, availability and price of the eye track systems. This paper describes the develop and...
Tongue movement ear pressure (TMEP) signals have been used to generate controlling commands in assistive human machine interfaces aimed at people with disabilities. The objective of this study is to classify the controlled movement related signals of an intended action from internally occurring physiological signals which can interfere with the inter-movement classification. TMEP signals were collected,...
The prediction task in national language processing means to guess the missing letter, word, phrase, or sentence that likely follow in a given segment of a text. Since 1980s many systems with different methods were developed for different languages. In this paper an overview of the existing prediction methods that have been used for more than two decades are described and a general classification...
The design details of integration of resistance type exercise machine with embedded computer technologies to obtain fine motion controls is reported. The developed exercise machine is capable to provide low velocity, low resistance and low range of motion in addition to higher levels. Ability to exercise at finest increment of velocity, resistance is incorporated. The user can interact with exercise...
It is widely acknowledged that computer is powerful tool to improve the quality of life of the people with disability. One problem is how the user manipulates the computer using suitable input device designed for him or her. This paper proposes tow pointing devices based on vision for the people with disability as input devices. These devices detect the position of the marks attached on the users...
INSCAPE aims at enabling non computer scientist people to use and master the latest Information Society Technologies for interactively conceiving, authoring, publishing and experiencing interactive applications and particularly in the field of virtual rehabilitation. It integrates a wide range of virtual reality concepts and offers the user with the possibility to bring interactivity to multimedia...
Music therapy addresses physiological, cognitive, and social needs of individuals and employs music to enhance quality of human lives through creation of positive changes. In this paper, we consider applying music therapy to human-computer interfaces, based on quality of life supporters (QLS) of self-explanatory type, and oriented to elderly and disabled people. QLS are multi-modal communicators for...
A robust iris localization and tracking algorithm based on computer vision is presented. The iris localization algorithm acts as a bootstrap for the tracking algorithm, providing it with a set of multiple hypotheses to restart from in the case of a tracking failure. Tracking is performed with a RANSAC-like robust method for ellipse fitting that incorporates search constraints so as to increase the...
The "Brainy Communicator" is a novel state-of-the-art Brain-Computer Interface (BCI) system developed by the Institute for Infocomm Research, Singapore. It allows users to interact with the environment by using just the brain signals. The primary objective of this work is to enhance the quality of life for the people with severe disabilities, by helping them regain some control and communication...
This paper is the continuation of a series of related work about experimentation of alternative ways of interaction with computers for disabled people (concretely with users suffering from cerebral palsy). In order to define an effective methodology to evaluate the usability and/or accessibility levels for this user profile, here, we start studying and evaluating (a) different interactive devices...
This paper describes a software-based system for communication and control by disabled people based on automatic recognition of phonemes. This program allows users to navigate around an alphabet board by making phonemic utterances, thus enabling the user to spell out messages. Phoneme recognition provides an alternative to speech recognition technologies for people who have lost the ability to speak...
