HCP M1

M1 –Explain how an HCI could be adjusted for specialist needs.

There are many reasons for creating specialist interfaces for example for people with major disabilities. For people with these disabilities a designer must consider if the interface he is going to design must be speech-activated for visually impaired people.

Visual impairment is a difficulty in seeing images or texts clearly depending on their colours and size.
Therefore designers must adapt to these difficulties by researching and developing their designs. Bright colours are difficult to be seen on bright backgrounds for example if it was yellow text applied onto a white background. Dark coloured texts must be used on bright backgrounds in order for them to be clear and stand out.

Specialist HCI is also used with Text-to-Voice interface. It allows people who have reading difficulties and pronunciation difficulties to be able to hear the text instead of reading it. This could however be used to learn a different language or the way words are pronounced in different languages. A good program that uses this interface is the Google translator, it can be used to translate other languages and then turn them into speech or simply turn any text into speech.

Voice recognition is a type of specialist HCI that allows people to speak instead of typing. It works by recording words and converting them into text. It is highly beneficial for users with disabilities. It is useful for those who have problems while using their hands, either because of Arthritis, Stress or Depression. There is a big chance that some people who use keyboards now will suffer from Repetitive Strain Injury and some users CTS (Carpel Tunnel Syndrome).

The input and output I designed to a specialists needs is the Database, as the text and background are very visible to the eye, visually impaired may be able to view it, if not access is a simple program and will feature a voice recognition. White and black are very easy colours to understand and seen as though I have done my database on cars, it has to help every customer that comes in and out so when they are completing their forms they must at all times be able to read and input data.
