Designing Software Application for Visually Impaired Clients

Questions: 1.As a Software Developer, you are required to Develop Programs that can be readily accessed by a Wide range of Clients.2.Discuss3 Ways in which you, Can use ICT to reduce your Carbon Footprint, and Contribute to Green ICT.3.Which of the Following are Projects, and which are Processes? Explain your answer. (i)Building a Computer, on a Production Line of Identical Computers (ii)Building a House, as One of a Series of Identical houses all over Australia (iii)Upgrading a Computer from Windows 7 to Windows 10 (vi)Upgrading all 120 Computers from Windows 7 to Windows 10 Answers: Designing Software application for Visually Impaired Clients For designing the software application for Visually impaired persons following considerations are took as they cannot control computers through eyes- Using the consistent and standard user Interface Elements This will help the visually impaired persons to use application easily, this can be done by using the operating system supplied controls, toolbars, menus, cursors and other elements. The screen readers are also applied for these kind of applications. Creating a Flexible User Interface This can be done by providing the contrast, cursor blink, sound effects , touch control and other elements to provide the accessibility to the users. Allowing the Full Keyboard Navigation This will help these peoples to control the system functionalities easily, with this applications that are fully keyboard driven with no or minimum pointing device requirement. Label all Icons and Graphics readable through Braille This will help these people to recognize elements easily. Provide adequate time and Sound Messages for support This will help these peoples to work easily. Designing Software application for Hearing Impaired Clients In order to provide support the Hearing Impaired peoples by using following steps- By providing the Library of sign language for the functions and utilities of the application in the software. By providing this facility to these people , these people can understand functionalities easily. By providing hearing aid in the applications . This can be done by providing the hearing aid facility to them according to their capability. By providing system that vibrates on alerting for any fault or any kind of message. This can be done by connecting devices to the system. Most importantly providing more text messages rather than any sound. These peoples will read and can work in better way. 2.Green ICT is the concept of implementing the computing or processing of Information technology in a manner so that it is Environmental Friendly. The objectives of this application is similar to green chemistry. In fact the actual percentage of transferring the co2 by IT Department is 0.2% of total co2 produced in environment. The main Equipments used in the IT are- Desktops and Laptops Printers , scanners , copier, projectors Smart phones, desktop phones Wireless connecting devices Networking Devices Data centre and their devices The factors, that effect the environment in IT are as follows- The way in which the equipments are manufactured. The conditions in which they are manufactured. What type of transport is used to transport them to other places . How much energy is consumed by them . The procedure of disposal of these equipments. The Green ICT is concerned about following issues in concern of environment- The equipments are sustainably manufactured with environment friendly conditions. The equipments should be developed that lasts longer. The equipments consume and waste less energy. The IT equipments should be used in the best way. The disposal of the System should be done in environment friendly way. The Methods to reduce carbon foot print are as follows- By using Systems with centrally connected data centre . By using Pen Drives, CDS and other digital storing devices to store data. By using Email, Fax and other modern methods to reduce paper work. 3.(i)It is a process as production of computers is a project, building a computer in this series is part of this project so this is a process of whole project (ii).Again it is a process as a developing the series of identical houses all over Australia is a project and building a house is a process. (iii)This is a project as it will consist of various processes in it. (vi)This is a project as consist of various processes in it.
