The object of this paper is to present a set of techniques integrated into two low-cost human computer interfaces. Although the interfaces have many potential applications, one main application is to help the disabled persons to attain or regain some degree of independent communications and control. The first interface is a voice-controlled mouse and the second one is an accelerometer-based mouse.

Housing Facilities

455 physically disabled persons were surveyed regarding their attitudes toward moving to housing facilities designed to give more independence to the disabled. While the majority were satisfied with their present living arrangements, one-third (134) of the total group expressed a desire to move to such a facility. Those willing to move were younger, had more severe disabilities and were more dependent upon others for daily needs. They were more often city dwellers who had lived in their present homes for a shorter period of time than those not willing to move.

Force Myography

A low-cost optical fiber force myography sensor for noninvasive hand posture identification is proposed. The transducers are comprised of 10 mm periodicity silica multimode fiber microbending devices mounted in PVC plates, providing 0.05 N−1 sensitivity over ~20 N range. Next, the transducers were attached to the user forearm by means of straps in order to monitor the posterior proximal radial, the anterior medial ulnar, and the posterior distal radial muscles, and the acquired FMG optical signals were correlated to the performed gestures using a 5 hidden layers, 20-neuron artificial neural network classifier with backpropagation architecture, followed by a competitive layer. The overall results for 9 postures and 6 subjects indicated a 98.4% sensitivity and 99.7% average accuracy, being comparable to the electromyographic approaches. Moreover, in contrast to the current setups, the proposed methodology allows the identification of poses characterized by different configurations of fingers and wrist joint displacements with the utilization of only 3 transducers and a simple interrogation scheme, being suitable to further applications in human-computer interfaces.

Wearable Electronic

Wearable electronics can be integrated with the human body for monitoring physical activities and health conditions, for human-computer interfaces, and for virtual/augmented reality. We here report a multifunctional wearable electronic system that combines advances in materials, chemistry, and mechanics to enable superior stretchability, self-healability, recyclability, and reconfigurability. This electronic system heterogeneously integrates rigid, soft, and liquid materials through a low-cost fabrication method. The properties reported in this wearable electronic system can find applications in many areas, including health care, robotics, and prosthetics, and can benefit the well-being, economy, and sustainability of our society.

The Impact

The purpose of this chapter is to analyze the history of technology and its founding purposes. The evolution of technology resulted in the creation and development of assistive technology. The impact of interactivity of human-computer interfaces on independence, employment, and organizations is analyzed and addressed in relations to disabilities. The utilization of assistive technology, in the disabled community, as well as in relations to the independence of the disabled are covered via the paradigms of assistive technology trainer and job developer for the disabled in the United States of America—capital of technology—Google, Yahoo, Microsoft, Cisco Systems—and capital of assistive technology.

Bci System

Brain–computer interfaces (BCI) are systems that use signals recorded from the brain to enable communication and control applications. One of the most important applications of BCI technology is that enables people who are severely paralyzed by amyotrophic lateral sclerosis, brainstem stroke, or other disorders to communicate, operate computer programs, or even control numerous devices. Moreover, elevators are probably the best option for disabled persons to expand their access and mobility within a house or a building. In this study, a prototype application is presented, together with an experimental setup of a BCI system that attempts to control an elevator. Practical application Many researchers are dealing with BCI systems that give the possibility to disabled people to control a variety of devices from wheelchairs to different home appliances, using the signals of their brain and forming a smart home services framework. This work comes to support this effort by presenting a case study, as a proof of concept, for an elevator BCI system that could be part of a complete “smart” home BCI system. The presented experimental setup proves that elevators with BCI functionalities are practically feasible and in an affordable cost, and that they could be a significant element within a “smart” residential building.

And Control

A cost-effective and portable Braille printer with low noise is designed in this study. To reach this goal, the compressive printing concept is used and the Braille typesetting, the signal transmission interface module, the signal control module, and the Braille printing cell are designed and integrated. To increase the portability, the Braille printer is designed to use A4 size paper and each page can print at most twenty-four rows and twenty-seven Braille characters in each row. The typesetting of the printing page is designed to contain twenty-seven side-by-side Braille printing cells and each printing cell contains two low cost flapper mechanisms for performing the low noise and cost-effective Braille print. The logic signal control module then controls a total of fifty-four flappers. The logic signals are transmitted through the integrated signal transmission interface module based on two common standard personal computer interfaces: Serial/RS232 and Universal Serial Bus 2.0. Subsequently, the pre-processing software is programmed based on the hardware developed. The integration of the software and hardware is successfully validated, and this newly designed Braille printer can be further used by the visually impaired for self-printing.

The Disabled

Environmental control units play a role in enabling disabled people to carry out routine and repetitive tasks (e.g. watching TV, making a phone call, etc.) in their home environments. Unfortunately, most commercially available environmental control units are either too expensive or they require the disabled persons' home environments to be remodelled. In this paper we report the development of a low-cost environmental control unit which enables disabled people to control mostly existing consumer electronics with an infrared remote control functionality. Finally, we use a simple scenario to evaluate the performance of the proposed environmental control unit.

The object of this paper is to present a set of techniques integrated into a low-lost eye tracking system. Eye tracking systems have many potential applications such as learning emotion monitoring systems, drivers' fatigue detection systems, etc. In this paper, we report how we use an eye tracking system to implement an "eye mouse" to provide computer access for people with severe disabilities. The proposed eye mouse allows people with severe disabilities to use their eye movements to manipulate computers. It requires only one low-cost Web camera and a personal computer. A five-stage algorithm is developed to estimate the directions of eye movements and then use the direction information to manipulate the computer. Several experiments were conducted to test the performance of the eye tracking system.
