How ICT effects a person with special needs Essay

All of these Keystrokes will save Paddy the hassle of going to the icons by using the mouse, which he can hardly see anyway. But, there is a problem the Keystroke commands. That is that they differ between each software package and if you learn one set of Keystrokes for, say Supernova, on computers in one department, and then you will have to learn a completely different one for Zoomtext, a different magnifier and Keystroke package, and it can result in a lot of confusion and frustration. There is also a piece of software that allows Paddy to talk into a microphone connected to the computer and it writes out what he says. A few years ago things like this would have been very unreliable and it would have resulted in him having to repeat a lot of words just to get a sentence complete. But now days they are very reliable once you have ‘worn them in’ and used them enough to get your voice recognised. This can take a long time and will result a lot of mistakes in work at first, but all in all they will become very, very useful in the future. As well as using computers to do work, Paddy also uses it to talk to his friends in the Royal National College for the Blind internally and also talk to people outside the college. To do this he uses Windows Messenger (or MSN Messenger to most), which is favoured by the students at the college because it has the ability to speak to friends directly without having to type. This means he can talk faster and be more precise. Although, the screen for msn is a lot smaller than other screens so it may be hard to read who is online and whom you are talking to. It is also mainly comprises of colour and images, and if the colours are reversed, then it may be too dark and Paddy may be unable to see it on the screen. Computers are not the only technology that has features, which enables blind and partially sighted people to use them. There are many household appliances that Paddy uses such as talking microwave ovens and cookers, which are very useful. As well as it being a fire hazard using a cooking appliance whilst unable to see what is being pressed, it also means that Paddy will be able to cook his own food and not relying on someone else to do things for him. But it is not only the only thing that limits his ability to cook and eat food. Many different foods come in similar or even the same shapes and sizes as one another, so for a blind or partially sighted person it could be almost impossible for them to distinguish between, say, dog food and beans. This is where Paddy would use mini magnifiers, which allow he to magnify the text in a small area, like a packet of food, and he’ll know what he has in his hand. It is compact so it could be taken anywhere with him, such as when he wants to read a bus timetable, or shopping in a supermarket. It is also relatively cheap, as all it really is a piece of magnifying glass and a casing. Not that he would be able to take it home, but there are magnifiers available in a larger size known as a CCTV. These are like the small magnifiers mentioned, but are a lot larger and will enable you to read a much bigger area. This can be used to read letters (as most blind people have to rely on others to read things to them such as confidential letters and even bank statements) and newspapers. They can also be linked up to a computer to magnify a piece of text and show it on screen, and at the Royal National College for the Blind Eye-Tech Exhibition they have CCTV’s where half the screen is what is magnified and the other half is what it being typed. This allows people like Paddy to, if they are copying something from a book, to do so without turning their head or having to go over it with a smaller magnifier. As well as college, Paddy has a social life with both friends and family. So, he bought himself a mobile phone. But he could not get just any mobile phone, because some of the new phones are almost impossible to use if you cannot properly see the key. A lot of the newer mobiles are made to be smaller so because of this the keys are getting flatter. Paddy bought himself a Motorola mobile phone like the one on the right. He chose this phone because of a few features on it that would make it a lot easier to use. He obviously cannot read texts, but that wasn’t a problem because he couldn’t write them easier. It has big keys, which as well as being easy to see, are easier to type with when typing in phone numbers. It also ha a feature a bit like a computer key board called hotkeys, where you simply hold a certain button and it rings a number. The phone has a built in radio so he does not have to get a compact radio which usually has small buttons which are impossible for Paddy to press. And the phone has voice dialling, which is what it says it is; you talk into the phone and it dials the person that you said. Firstly, you have to record the tag for each person, but once you’ve done it, the voice dialling would be very useful to Paddy when dialling his friends and family. There are speaking phones, though, but these can cost at least i 200, so the cost outweighs the benefits of it. Paddy, as some may think, is not just someone who lazes around the home, he is a very fit person. He evens works and trains in the Royal National College for the Blind gymnasium. In the gym, there are many specially adapted pieces of equipment that allows Paddy and others to use the gym as any others would. There are talking watches, talking stopwatches and even talking Blood Pressure and Heart Rate Monitors. These will let the people at the Royal National College for the Blind to use the gym as well, and sometimes better, than people in other gyms. The college even lets people come to the gym where they can be given a health and fitness assessment by a blind person. All of this technology means that a blind or partially sighted person is able to do everything someone with perfect sight. They can, in some circumstances, do it better. All they need is a bit of help to do it, and as technology evolves for you and I, it also evolves for those who have disabilities both physically and mentally.
