Design Considerations

The existing design of ultrasound real-time scanners is not satisfactory from the standpoint of operator comfort or efficient use. As currently configured, these units are cumbersome and fatiguing to use and require unnecessarily complex and time-consuming movements on the part of the operator. Redesigning ultrasound scanners so that they conform to accepted principles of ergonomics or human-factor engineering should make it possible to achieve increased efficiency and improved study quality.

The Internet Of Things

Design and development of systems for delivering real-time information to people with disabilities and elderly persons need to be based on defined user requirements. For this purpose, the user requirements have been defined in this paper according to the everyday needs of people who use traffic networks and move in closed spaces. The logical presentation of the functionality of the informing system operation and its subsystems includes all the information (data) important for designing a user information delivery system. The paper presents a conceptual architecture system for delivering user informing services related to the environment based on the Internet of Things concept. The aim of the user informing service is an increase in the level of mobility of persons with disabilities and the senior age groups of users. In order to check the operation of the proposed architecture, the informing system operation was monitored on Arduino Uno and Raspberry Pi platforms in laboratory conditions. A simulation confirmed the interdependence of individual data from different subsystems in order to provide real-time information to the system user. The proposed conceptual architecture can contribute to a more efficient approach to the modeling of assistive technologies (with the aim of informing the users) based on dew/fog/cloud technologies in the Internet of Things  environment.

Today, components and Component Based Development (CBD) is seen as one of the important events in the evolution of information technology. Components and CBD offer the promise of a software marketplace where components may be built, bought, or sold in a manner similar to components in other industries. In the light of the ongoing developments, in the manner and art of developing software systems, it is important to consider how the Computer Aided Systems Engineering (CASE) environment that supports building these systems can be produced on a CBD approach. In spite of the fact that CASE environments have been around since the ’70s, there are still many problems with these environments. Among the problems of CASE environments are the lack of conceptual models to help understand the technology, the poor state of user requirements specification, inflexible method, support and complicated integration facilities, which contribute to the dissatisfaction in CASE users.
