ANALYSIS OF THE USABILITY AND ACCESSIBILITY OF WEBSITES IN VIEW OF THEIR UNIVERSAL DESIGN PRINCIPLES

Universal design is a strategic approach for planning and designing both the products and their environment, aimed at making a given product available to the widest number of possible users. It ensures equality for all of them and the opportunity to participate in the society. This concept is also crucial in the process of designing and developing software. The research was conducted with the use of four services, three of them were implemented for the purpose of this study. Two of them took into consideration the principles of universal design, while the others did not. The aim of the study was verification of the level of usability and accessibility of services by means of three independent methods: the LUT (Lublin University of Technology) checklist, an assessment taking into account WCAG 2.0 (Web Content Accessibility Guidelines) standards using the automatic WAVE evaluation tool (Web Accessibility Evaluation Tool) and a device allowing to track the movement of the eye while performing various tasks on websites. The websites were assessed by twenty experts in the field of creating web application interfaces, using the LUT checklist. The time to the first fixation (TTFF) that it took respondents to look at  specific website elements was measured using the eye tracker device and iMotions software. All websites were checked by means of the WAVE tool to detect irregularities and non-compliance with universal design standards. The analysis performed clearly indicated that websites that follow the universal design guidelines were more useful, intuitive and accessible for users. It might be concluded that interfaces allow to find necessary information and perform desired actions in a shorter time when prepared in accordance with the principles of universal design

Cyber Physical System for Continuous Evaluation of Fall Risks to Enable Aging-In-Place

Every year, one out of three adults over the age of 65 falls, and about 30% of the falls result in moderate to severe injuries. The high rate of fall-related hospitalizations and the fact that falls are a major source of morbidity and mortality in older adults have motivated extensive interdisciplinary clinical and engineering research with a focus on fall prevention. This research is aimed at developing a medical Cyber Physical System (CPS) composed of a human supervised mobile robot and ambient intelligence sensors to provide continuous evaluation of environmental risks in the home. As a preventive measure to avoid falls, we propose use of mobile robots to detect possible fall risks inside a house. As a step-up to that, we also define a control framework for intelligent, networked mobile robots to semi-autonomously perform assistive and preventive tasks. This framework is integrated in a smart home that provides monitoring and control capabilities of environmental conditions such as objects blocking pathways or uneven surfaces. The main outcome of this work is the realization of this system at Worcester Polytechnic Institute\u27s (WPI) @Home testbed

Web Portal Development Issues: Usability, Site Managementand Content Management

This paper is written with the aim to present the concept of integration between usability, content management and site management in order to design an effective tourism website. The study is based on the common problems that surrounds most of the web developers such as useless contents plus poor design that did not reflect the audience needs and poor site management such as broken links and unsorted web pages that are hard to be keep track. The study will cover on the application of the usability techniques to describe what is right and what is wrong with websites seen by millions. It will also covers on how the site management and content management play important roles in achieving high usability of the website. Assessing usability through case studies and following some guidelines on achieving effective site management and good content management will be part of the methods use in this project. The findings from this study highlight the importance of these existing guidelines and the need to modify or implement some of them to suit the requirement of a good tourism website through a prototype developed in this project

There is a positive relation between the communications system and the Quality of Workers Relations, in addition to that communications system plays the role of mediator in the relations between the availability of TQM requirements as a whole and The Quality of Workers Relations as a whole, However, the result of the multiple regression analysis of the dimensions of TQM on The Quality of Workers Relations in the existence of a Communications system as a mediator has shown that the relations is not significant for the "focus on clients and senior management support", The study recommended a group of recommendations: The need for senior management to apply the dimensions of TQM in all departments, Focusing on customers and developing communication methods between employees, and take care of enhancing the Quality of Workers Relations, and set customers’ needs as the main goal.صديق بلل إبراهي

RETAIL HEALTH & SAFETY DIGITAL MANAGEMENT SYSTEM

Health and Safety procedures and documentations are one of the many tasks that need to be done by a small retail shop, they are also one of the most difficult things to manage daily as all those can build up during the day/week. Inside Health and Safety there are many subcategories that need to be administered (maintenances, trainings and checklists for example) which can be very overwhelming for any management team notably in small retail shops as they do not have the permanent personnel to be able to maintain an organised system. This project aims to create a management software to assist a business to conduct all those procedures in an easier and more efficient manner

Programmable Vibration Table Retrofit with Eagle Medical

This project aimed to repair and upgrade a vibration table used for package testing for the sponsor, Eagle Medical - a medical packaging and sterilization company based in Paso Robles, California. The current vibration table is not programmable and lacks circuit diagrams, making it difficult to repair. In addition, it is not functional due to internal circuitry issues and power requirements. To address these issues, the team will implement several upgrades to improve the product and allow for better random cyclic vibration testing. A full assessment of the existing vibration table will be conducted to ensure the viability of these proposed modifications for a successful outcome. The document provides information on the project\u27s background, objectives, and project management, including the design process, project timeline, and Gantt chart. Additionally, the document will provide information regarding our morphology, conceptual designs/evaluation, and failure analysis. This document also includes the detailed design, manufacturing plans, testing plans, and testing data/analysis, and instructions for use. We followed a 5-phase design process typically employed in industry: product discovery, project planning, product definition, conceptual design, and product development. During the Winter Quarter, we went through the first 4 phases, and all of Spring Quarter was spent in product development. In product discovery, we identified the needs of Eagle Medical and investigated other vibration tables on the market. During project planning, we mapped out our key deadlines using a Gantt chart. In product definition, we created the scope of the project and began creating our engineering specifications. In conceptual design, we took those specifications and started evaluating possible concepts using morphology. During product development, we built our prototype and tested it against our engineering specifications. The key customer requirements were that the new vibration table vibrates according to given standards, outputs frequency data, has vibration schedules, uses microcontrollers, has easily accessible data, updated/reliable electronics, and has a human-machine interface. The customer additionally wanted a circuit diagram, an easily serviceable table, and asked that we salvaged as much of the old table as possible. Our test plan revealed key results. The aesthetic satisfaction scored a 10. The vibration table achieved our max vibration goal of 18 m/s^2. We showed that the vibration table does have accurate control of the rotations per minute. We also showed that the motor wire temperature did not change, indicating that our wires are properly specified. We showed that the power supply had very little variance, so our electronics should be safe from voltage spikes. We showed that it takes approximately 5.2 seconds to upload a vibration test. We also showed that the emergency stop works with 100% certainty. Finally, we performed GUI unit testing and all units passed
