Introduction

Transfer-Encoding: chunked ´╗┐Task 4 ? M3 & D2 Introduction My recommendations for the new PCs and software have been accepted by the senior leaders at Feltham Community College. I have been asked to set up the new computer system and ensure that all items are installed correctly. The computers needed to be suitable for pupils who are visually impaired as asked by the SEN department. Meaning I had to change the user settings to make using the computer suitable and easy for the pupils to use. Mouse I changed the mouse settings in many different ways. Firstly, I changed the size and colour of the mouse. I did this by going to the control panel and then to ease of access. I chose to go for the extra-large black colour. This is because it makes the mouse easy to see as it is large and bold. This will make it easy for the user to use and will be able to navigate easily around the screen. In addition, I changed the mouse visibility to long. This is because if the pointer was short it may be difficult for the user to be able to use the computer; they have vision problems therefore if it disappears too quickly they won?t be able to see it. ...read more.

Resolution Furthermore, I changed the screen resolution to the largest setting which was 1440 X 900. I also changed the settings to a larger screen. This makes the screen larger making icons and text bigger. This is good for the user as it will be easier to see. I also enabled the magnifier to allow the user to focus on certain places where they may find it hard to see. Maintenance I have competed many maintenance tasks and tests to ensure the computer will work efficiently. I defragmented the disk. Disk Defragmenter rearranges fragmented data so your disks and drives can work more efficiently. Doing this will improve the computers performance because the user will be able to access files more easily due to them being organised in one place. In addition, the computer will run faster because it doesn?t need to work as hard to access files which are scattered throughout the drive. In addition, I ran a disk clean up. Disk clean up can help find unused files that can be deleted. It gives you the option to safely remove the unused files to help improve the performance of the computer by making it run faster or frees spaces so that more used files can be saved. ...read more.

Conclusion

Some may also have features to provide a calendar, phone book, the internet, e-mail and run windows based operating systems. They feedback information by speech output. This would be better for the visually impaired because it relies on speech and not sight. However, note takers are expensive therefore it may not be suitable to purchase one for the pupils. The price for a note taker can vary from £90 to £200. Despite it being expensive, it is beneficial for the user. It may be beneficial to use ClaroRead V6 software. This software, will read back letters, words and sentences as they are typed, so that struggling writers can listen for mistakes whilst writing. Clicking anywhere in a Word document and pressing the play button on the toolbar will read out the text, highlighting each sentence as it is spoken, and each individual word spoken in a contrasting colour. ClaroRead will also grey or dim out sentences not being spoken out to allow the user to concentrate on the sentence being read. It can convert text into an audio file that can be transferred to an MP3 player, iPod or mobile phone and played back. This would be very beneficial and will make it easier for the user to use the computer. This software is user £50 therefore would be suitable to purchase to improve performance for the user. ...read more.
