ABSTRACT Electronic aids to daily living (EADLs) are devices that facilitate the operation of electrical appliances in a given environment for a person with a severe physical disability. These specialized devices can provide tremendous psychological and functional benefits to someone with a severe disability, their family members and caregivers. This article provides an overview of the utility, functionality, access, acquisition, and evaluation of EADLs. It also highlights challenges in obtaining and measuring the benefits of these devices.

    ABSTRACT: An electronic aid for daily living, using Morse code as an adapted access communication tool, is presented in this study. The study aim is to help quadriplegics operate appliances, allowing them to live more independently. This system consists of four modules: the assistive computer input device, application software, communication control board, and the appliance control nodes. ZigBee is used to avoid the problem of "line of sight" encountered with infrared transmission to permit long-distance transmission without space limitation. Also, a visual design methodology reduces the burden of operating the application software. Users can easily click control buttons on the application software through the assistive computer input device. Within a one-month evaluation, three subjects, quadriplegics who were users well-trained on operating the assistive computer input device, could smoothly manipulate the system from the beginning and became dependent on the system progressively. Data based on system activity was recorded. Also, the subjects and care-givers were questioned about their experience with the system during the evaluation period. According to the results, the three subjects totally agreed that the system changed their life significantly and the most used function was the control of television. Finally, care-givers of the three subjects appreciated the benefit of this system. They experienced fewer interruptions of their daily routine.
